Description:Technology
The present invention relates to combing machines used in the preliminary spinning process of textile manufacturing, and particularly to a top comb locking device suitable for a combing machine.
Background technology
In the textile industry, combing machines are utilized for fiber preparation during the spinning process. They are typically installed in yarn production lines between carding machines and drawing frames. The primary purpose of a combing machine is to remove short fibers from the sliver produced by the carding machine, thereby enhancing the staple length of coarse fiber materials. Additionally, the combing operation improves the parallel orientation of individual fibers within the fiber web extracted from the carding machine. An ancillary effect of the combing operation is the removal of neps and cottonseed hulls from the fiber web.
Generally, textile combing machines consist of six to eight combing heads. Each combing head features a nipper device, a circular comb, and a pair of detaching rollers. The nipper device includes an upper nipper and a lower nipper, which secure the fiber lap fed in each time to a predetermined length. The circular comb combs the fiber fringes of the lap sheet, and the combed fiber web is pushed towards a pair of detaching rollers by the forward movement of the nipper device. As the fiber web moves forward, the pair of detaching rollers rotate in reverse, moving the previously drafted fiber web backwards. Consequently, the trailing end of the previous fiber web overlaps with the leading end of the newly combed fiber web. When the pair of detaching rollers rotate forward, the lap is withdrawn from the nipper device, and the top comb piercing through the fiber web performs the combing. While repeating the above operations, the fiber webs fed in by each combing head are bundled and drafted. Calendar rollers compress the bundled and drafted fiber web, thereby forming a combed sliver.
Typically, the top comb of a combing machine is equipped with a holder comprising multiple linearly stacked comb needles. The top comb at each combing station is supported on a top comb carrier located at both ends of each combing station. A single top comb fixing holder usually secures the ends of two adjacent top combs between combing stations.
In known devices, a spring plate is provided on the top comb carrier to lock adjacent top combs supported on the top comb carrier via a fixing component. The locking and unlocking of the spring plate on the top comb are performed during the disassembly of the top comb for maintenance operations, such as fiber lap feeding after fiber breakage, top comb replacement, etc. Due to the frequent replacement operations of the top comb holder on the top comb carrier, mechanical stress and friction are continually generated between the top comb holder and the spring plate, leading to wear at both ends of the top comb holder. The wear on the top comb holder also affects the effective locking of the spring plate at both ends of the top comb holder.
Furthermore, due to wear on the top comb holder, the position of the top comb on the top comb carrier becomes uneven, and it is locked in place by the spring plate. The existing spring plate fails to provide an effective and reliable locking mechanism for the top comb, ultimately leading to detachment/vibration of the top comb during machine operation. This, in turn, causes severe damage to the top comb and results in component replacement and extended downtime, thereby incurring high costs and production losses. In existing high-speed machines, the likelihood of top comb detachment is even greater if the locking is improper. Therefore, improper locking of the spring plate on the top comb affects the overall quality of the processed fiber material and also leads to inefficiency in the textile combing machine. Consequently, there is a need to improve the top comb locking device for combing machines.

Invention Disclosure
To address the aforementioned technical issues, the present invention provides a top comb locking device suitable for high-speed running combing machines, which effectively locks the top comb. This device prevents unnecessary damage to the operating components of the combing machine due to the detachment of the top comb, thereby overcoming issues of machine downtime and productivity loss.
The technical solution of the present invention is as follows:
A top comb locking device suitable for a combing machine, comprising a top comb holder fixed on the combing machine, characterized in that: a top comb bracket is fixedly connected to the top comb holder through at least one spring plate. Each spring plate includes a fixing portion and a clamping portion fixedly connected to the top end of the fixing portion. The clamping portion of each spring plate is engaged with the upper surface of the top comb bracket, and the fixing portion of each spring plate is connected to the lower end of the top comb bracket. Fasteners fix the lower end of the top comb bracket and the fixing portion of the spring plate adjacent to the lower end of the top comb bracket to the top comb holder.
Furthermore, the fixing portion of the spring plate is a rectangular plate; the clamping portion is fixedly connected to the top end of the rectangular plate and is an arcuate section that bends upwards from the top end of the fixing portion towards the top comb bracket. The curvature of the clamping portion is such that when the upper end of the top comb bracket fits inside the clamping portion, the outer surface of the upper end of the top comb bracket can tightly adhere to the inner surface of the clamping portion.
Furthermore, the clamping portion of the spring plate is divided into two segments. Each segment of the clamping portion extends outward from its central axis in a direction perpendicular to the central axis. The length of each segment of the clamping portion is sufficient to fixedly support one end of the upper portion of adjacent top combs arranged consecutively on the top comb holder.
Furthermore, the fixing portion of the spring plate is also divided into two segments. Each segment of the fixing portion extends outward from its central axis in a direction perpendicular to the central axis. The length of each segment of the fixing portion is sufficient to fixedly support one end of the lower portion of adjacent top comb brackets arranged consecutively on the top comb holder.
Furthermore, the top end of the clamping portion of the spring plate is fixedly connected with an S-shaped second clamping portion. The second clamping portion bends upwards from the top surface of the clamping portion away from the direction of the top comb bracket, forming a bent section, and then extends obliquely upwards away from the direction of the top comb bracket to form a pressing portion. The terminal surface of the pressing portion does not exceed the highest point of the curvature of the clamping portion. The top surface of the pressing portion, which is far away from the top comb bracket, extends obliquely upwards towards the direction of the top comb bracket to form an inclined vertical plate.
Furthermore, the second clamping portion of the spring plate is divided into two segments. Each segment of the second clamping portion extends outward from its central axis in a direction perpendicular to the central axis. The length of each segment of the second clamping portion is sufficient to fixedly support one end of the upper portion of adjacent top combs arranged consecutively on the top comb holder.
Furthermore, the clamping portion of the spring plate has a relatively small flexibility or bending stiffness, while the fixing portion of the spring plate has a relatively large flexibility or bending stiffness. The flexibility and stiffness of the clamping portion are both less than those of the fixing portion.
Furthermore, the clamping portion of the spring plate has a through-hole along its central axis.
Furthermore, the fastener is a concave baffle plate, and the length of the middle concave portion of the concave baffle plate is greater than the length of the fixing portion of the spring plate. The lower end of the concave baffle plate has a fastener fixing hole.
Furthermore, along the lengthwise direction of the fastener, there are fastener side retaining edges on both sides.
Furthermore, the top comb holder includes a holder fixing rod and a bracket docking block on the side top surface of the holder fixing rod facing the fastener. The lower end of the bracket docking block has a holder fixing hole. The middle part of the side surface of the bracket docking block facing the fastener has an inner groove along its lengthwise direction. Both lengthwise side edges of the bracket docking block have an inwardly concave holder groove. The lower end of the top comb bracket is engaged in the holder groove. The connecting locking element passes through the fastener fixing hole and stops at the holder fixing hole, thereby fixing the lower end of the top comb bracket and the fixing portion of the spring plate adjacent to the lower end of the top comb bracket to the top comb holder.
Furthermore, the bottom end of the fixing portion of the spring plate has a holder connecting strip. The holder connecting strip is a columnar body extending along the lengthwise direction of the bottom end of the fixing portion and is rotatably placed in the inner groove.
The beneficial technical effects of the present invention are as follows: The present invention provides a top comb locking device that includes a top comb holder fixed on the combing machine. The top comb bracket is fixed to the top comb holder using spring plates, and the top comb is fixed to the top comb bracket. The spring plate includes a fixing portion, a clamping portion, and a second clamping portion. The fixing portion fixes the lower end of the top comb bracket to the top comb holder, the clamping portion engages with the upper end of the top comb bracket, and the second clamping portion further applies a downward pressure to the upper end of the top comb bracket, thereby effectively locking the top comb bracket and the top comb.
Moreover, due to the relatively small flexibility or bending stiffness of the clamping portion of the present invention, the upper end of the top comb bracket can be securely locked inside the clamping portion, preventing it from loosening. The fixing portion has a relatively large flexibility or bending stiffness. Since the fixing portion is fixedly connected to the lower end of the top comb bracket, and the top comb installation part is fixedly connected with the top comb, the high-speed movement of the top comb will simultaneously cause a certain degree of vibration in the top comb bracket. Configuring the fixing portion with a relatively large flexibility or bending stiffness provides a certain degree of elasticity in the connection between the fixing portion and the top comb installation part of the top comb bracket, making it more stable compared to a rigid connection between the two.
Additionally, the clamping portion of the spring plate in the present invention has a through-hole structure to improve the stress distribution of the clamping portion, offsetting the vibrational force applied to the spring plate by the top comb bracket due to the high-speed movement of the top comb. This makes the connection between the top comb bracket and the spring plate more stable during high-speed operation of the combing machine, preventing unnecessary damage to the operating components of the combing machine due to the detachment of the top comb, and overcoming issues of machine downtime and productivity loss.
Furthermore, since the bottom end of the fixing portion of the spring plate in the present invention also has a holder connecting strip, which is rotatably placed in the inner groove of the top comb holder, when the top comb bracket or the top comb fixedly connected to the top comb bracket needs to be replaced due to wear, simply pulling the spring plate away from the direction of the top comb holder can unlock the top comb bracket, thereby facilitating the replacement of a new top comb bracket or top comb without the need to frequently unlock the top comb holder fixedly connected to the combing machine. This simplifies the replacement steps and improves production efficiency.

Detailed Embodiments
To provide a clearer understanding of the technical means of the present invention and enable its implementation according to the content of the specification, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are used to illustrate the present invention but are not intended to limit its scope.
The present invention provides a top comb locking device suitable for a combing machine, which is applied to the combing machine. As shown in Figure 1, the fiber web 1 in the combing machine 1a is fed to a rotating circular comb 2. During the combing process, the fiber web 1 is fed by a feed roller 3 and held by a set of nippers (an upper nipper 4 and a lower nipper 5). After the combing cycle is completed, the combed fiber tufts are merged with previously combed fibers, and at the same time, they are pulled between separator rollers 8 by engaging with a top comb 6 among the fiber tufts. Meanwhile, the separator rollers 8 pull the combed fiber web away from the feed roller 3 and the combed fibers. During this process, necessary improvements can be made to the removal of short fibers and the parallelization of individual fibers in the fiber web. Typically, the top comb 6 is mounted on a top comb support 7.
Embodiment 1
The present invention discloses a top comb locking device suitable for a combing machine, which includes a top comb bracket 10 fixed on the combing machine 1a. A top comb support 7 is fixedly connected to the top comb bracket 10 via at least one spring plate 9. Fasteners 11 connect and lock the spring plate 9 and the top comb support 7, which is in contact with the spring plate 9, to the top comb bracket 10. A top comb 6 is removably mounted on the top comb support 7.
As shown in Figure 6, the top comb bracket 10 of the present invention includes a bracket fixing rod 14 and a bracket docking block 13 on the side top surface of the bracket fixing rod 17 facing the fasteners 11. The bracket fixing rod 14 is fixedly connected to the combing machine 1a. A bracket fixing hole is provided at the lower end of the bracket docking block 13, and an inner groove 15 is provided along the length direction in the middle of the bracket docking block 13. A bracket clamping slot 16, which is concave towards its central axis, is provided on both sides of the bracket docking block 13 along the length direction. The lower end of the top comb support 7 is clamped in the bracket clamping slot 16.
As shown in Figure 6, the fastener 11 of the present invention is a concave baffle, and the length of the concave portion in the middle of the concave baffle is greater than the length of the fixed portion of the spring plate. A fastener fixing hole is provided at the lower end of the concave baffle. A fastener side baffle 12 is provided on both sides of the concave baffle along its length direction. In this Embodiment 1, each fastener side baffle 12 is cylindrical. When the present invention is assembled and used, the connecting locking element sequentially passes through the fastener fixing hole and stops at the bracket fixing hole, thereby fixing the lower end of the top comb support 7 and the fixed portion of the spring plate 9 in contact with the lower end of the top comb support 7 to the top comb bracket 10. At this time, the outer surfaces on both sides of the top comb bracket 10 along the length direction just abut against the inner surfaces of the corresponding two fastener side baffles 12, thereby further reinforcing the connection with the top comb bracket 10. The connecting locking element used in the present invention is a screw.
In this Embodiment 1, the top comb support 7 includes a top comb mounting portion 18 and a bracket support portion 19. The top comb mounting portion 18 is a rectangular strip, and an inverted V-shaped notch is opened at the bottom edge of one end of the rectangular strip. The opening of the inverted V-shaped notch faces the top comb 6. The inverted V-shaped notch divides the top comb mounting portion into a long side and a short side. The top comb 6 is fixedly connected to the vertical side surface of the long side on one side of the inverted V-shaped notch of the top comb mounting portion and faces the top comb bracket 10. The short side of the top comb mounting portion 18 is vertically inserted into the bracket clamping slot 15 on one side of the bracket docking block 13. An arcuate bracket support portion 19 is integrally formed at the top end of the top comb mounting portion 18, bending upwards and towards the direction of the top comb bracket 10. When the short side of the top comb mounting portion is inserted into the bracket clamping slot 15 on one side of the bracket docking block 13, the bottom end of the bracket support portion 19 just abuts against the top surface of the bracket docking block 13, thereby initially fixing the top comb support 7 to the top comb bracket 10.
As shown in Figures 2 and 3, in this Embodiment 1, the spring plate 9 includes a fixed portion 92 and a clamping portion 91 integrally formed at the top end of the fixed portion 92. The fixed portion 92 of the spring plate 9 is a rectangular plate. A clamping portion 91 is fixedly connected to the top surface of the rectangular plate. The clamping portion 91 is an arcuate portion that bends upwards from the top end of the fixed portion 92 and towards the direction of the top comb support 7. In addition, a bracket connecting strip 17 is provided at the bottom end of the fixed portion 92 of the spring plate 9. The bracket connecting strip 17 is a cylindrical body extending along the length direction at the bottom end of the fixed portion 92.
The bracket connecting strip 17 is placed in the bracket clamping slot 15 on the top comb bracket 10 mentioned above. At this time, the fixed portion 92 of the spring plate 9 is placed on the side surface of the bracket docking block 13 of the top comb bracket 10 facing the fasteners 11.
When the positions of the fastener fixing hole at the lower end of the fastener 11 and the bracket fixing hole at the lower end of the top comb bracket 10 correspond to each other, the two sides of the fastener 11 along its length direction just cover the two ends of the inner groove 15, that is, the bracket connecting strip 17 is just enclosed within the inner groove 15. At this time, the fixed portion 92 of the spring plate 9 is located in the middle concave portion of the fastener 11. A screw sequentially passes through the fastener fixing hole and stops at the bracket fixing hole, thereby initially fixing the top comb support 7 to the top comb bracket 10. At the same time, the clamping portion 91 of the spring plate 9 mentioned above is clamped on the surface of the bracket support portion 19 of the top comb support 7, and the bending curvature of the clamping portion 91 can just accommodate the bracket support portion to be clamped therein. When the outer surface of the bracket support portion of the top comb support 7 can tightly fit against the inner surface of the clamping portion 91, the spring plate is used to finally lock the top comb support 7 to the top comb bracket 10.
In addition, an S-shaped second clamping portion 93 is integrally formed at the top end of the clamping portion 91 of the spring plate 9. The second clamping portion 93 bends upwards from the top surface of the clamping portion 91 and away from the direction of the top comb support 7 to form a bending portion, and then extends obliquely upwards along the direction away from the top comb support 7 to form a pressing portion. The terminal surface of the pressing portion does not exceed the highest point of the curvature of the clamping portion 91. The top surface of the pressing portion mentioned above, which is away from the top comb support 7, extends obliquely upwards and towards the direction of the top comb support 7 to form an inclined vertical plate. The pressing portion of the second clamping portion 93 just abuts against the arcuate segment from the arcuate highest point to the arcuate lowest point of the bracket support portion of the top comb support 7, thereby forming an obliquely downward pressing force on the bracket support portion of the top comb support 7. This further enhances the clamping and locking force of the spring plate 9 on the top comb support 7.
Moreover, the clamping portion 91 has a relatively small flexibility or bending stiffness, which allows the bracket support portion of the top comb support 7 to be firmly locked within the clamping portion 91 and prevents it from loosening. The fixed portion 92 has a relatively large flexibility or bending stiffness. Since the fixed portion 92 is fixedly connected to the top comb mounting portion of the top comb support 7, and the top comb 6 is fixedly connected to the top comb mounting portion, the high-speed movement of the top comb 6 will simultaneously cause a certain degree of vibration in the top comb mounting portion. Configuring the fixed portion 92 with a relatively large flexibility or bending stiffness makes the connection between the fixed portion 92 and the top comb mounting portion of the top comb support 7 have a certain elasticity, which is more stable compared to a rigid connection between the two.
In addition, a through hole can be opened along the central axis of the clamping portion 91 of the spring plate to improve the stress distribution of the clamping portion 91, thereby offsetting the vibrational force generated by the high-speed movement of the top comb 6 on the spring plate to the top comb support 7. This makes the connection between the top comb support 7 and the spring plate more stable when the combing machine operates at high speeds.
When the top comb support 7 is worn and needs to be replaced, the spring plate can be pulled in the direction away from the top comb bracket 10. The bracket connecting strip 17 on the spring plate is stressed and rotates in the inner groove 15 in the direction away from the top comb bracket, thereby unlocking the top comb support. This facilitates the replacement of a new top comb support or top comb without the need to frequently unlock the top comb bracket fixedly connected to the combing machine, thereby simplifying the replacement steps and improving production efficiency.
Embodiment 2
Compared with Embodiment 1, Embodiment 2 differs only in the structure of the clamping portion of the spring plate 9, while the structures and connections of the remaining components are identical and will not be repeated here. In Embodiment 2, the spring plate 9 comprises a fixing portion 9b, a clamping portion 9a, a second clamping portion 9c, and a bracket connecting strip 17a. The structure of the fixing portion 9b and the bracket connecting strip 17a of the aforementioned spring plate 9 are the same as those of the fixing component 92 of the spring plate 9 in Embodiment 1, and will not be repeated here.
As shown in Figure 3, in practical applications, a single top comb bracket 7 is typically fixed between the ends of two adjacent top combs at a workstation of a combing machine 1a. Thus, the aforementioned two adjacent top comb brackets 7 can be fixed onto the same top comb holder 10, thereby reducing the number of parts and saving production costs.
The short sides of the inverted V-shaped notch side of the top comb mounting portion of the aforementioned two adjacent top comb brackets 7 are vertically inserted into the bracket slots 15 on one side of the bracket docking block 13. At this point, the bottom ends of the bracket support portions 19 of the aforementioned two adjacent top comb brackets 7 abut against the top surface of the bracket docking block 13, thereby initially fixing the aforementioned two adjacent top comb brackets 7 onto the top comb holder 10 simultaneously.
When the fastener fixing hole at the lower end of the fastener 11 aligns with the bracket fixing hole at the lower end of the top comb bracket, the two sides of the fastener 11 along its length direction cover the two ends of the inner groove 15, effectively enclosing the bracket connecting strip 17a within the inner groove 15. At this time, the fixing portion 9b of the spring plate 9 is located in the middle concave portion of the fastener 11. A screw is sequentially passed through the fastener fixing hole and stopped at the bracket fixing hole, thereby initially fixing the aforementioned two adjacent top comb brackets 7 onto the top comb holder 10.
As shown in Figure 4, the top end of the fixing portion 9b is integrally formed with the clamping portion 9a, which has the same structure as the clamping portion 91 in Embodiment 1. The difference lies in that the clamping portion 9a is divided into two segments. Each end of the clamping portion 9a, i.e., each clamping component 9a, extends a distance in a direction perpendicular to its central axis centered on its central axis. The length of each segment of the aforementioned clamping portion 9a can fixedly support one end of the bracket support portion of two adjacent top comb brackets 7 arranged continuously on the top comb holder 10. The one end of the bracket support portion of the aforementioned adjacent two top comb brackets 7 is simultaneously engaged within the clamping component 9a, and each one end of the bracket support portion of the adjacent top comb brackets 7 is located within each segment of the clamping component 9a. This achieves the final locking of the two adjacent top comb brackets 7 onto the same top comb holder 10 using the same spring plate 9.
Furthermore, the top end of the clamping portion 9a in this Embodiment 2 is integrally formed with an S-shaped second clamping portion 9c, which has the same structure as the second clamping portion 93 in Embodiment 1. The difference lies in that the second clamping portion 9c is divided into two segments. Each segment of the aforementioned two segments of the second clamping portion, i.e., the second clamping portion 9c, extends a distance in a direction perpendicular to its central axis centered on its central axis. The length of each segment of the aforementioned second clamping portion 9c can fixedly support one end of the bracket support portion of adjacent top comb brackets 7 arranged continuously on the top comb holder 10. That is, each segment of the pressing portion of the second clamping portion 9c abuts against one end of the bracket support portion of the aforementioned adjacent two top comb brackets 7 on the same side as the short side of their top comb mounting portion, thereby exerting an oblique downward compressive force on the bracket support portions of the two adjacent top comb brackets 7. This further enhances the clamping and locking force of the spring plate 9 on the two adjacent top comb brackets 7.
Embodiment 3 for Patent Application
Compared to Embodiment 2, Embodiment 3 features a spring plate 9 with clamping portions 9d, second clamping portions 9f, and bracket connecting strips 17b that are identical in structure and function to the corresponding parts in Embodiment 2 (i.e., clamping portions 92, second clamping portions 93, and bracket connecting strips 17b). The structures and connections of the other components remain the same. The only difference lies in the structure of the fixing portion 9e of the spring plate 9.
As shown in Figure 5, in Embodiment 3, the fixing portion 9e of the spring plate 9 is also a rectangular plate. Compared to Embodiment 2, the distinguishing feature is that the fixing portion 9e is divided into two segments. Each segment of the fixing portion 9e extends in a direction perpendicular to its central axis, centered on this axis. In other words, the length of the fixing portion 9e in Embodiment 3 is greater than that of the fixing portion 9b in Embodiment 2. Compared to Embodiment 2, the structures and functions of the clamping portions 9d and second clamping portions 9f of the spring plate 9 in Embodiment 3 remain unchanged. By dividing the fixing portion 9e into two segments, the contact area between the fixing portion 9e and the butt joint block 13 of the top comb bracket upper support is increased, thereby enhancing the fixed connection between the spring plate 9, the short sides of the top comb mounting portions of two adjacent top comb supports 7, and the same top comb bracket 10.
The above description is merely a preferred embodiment of the invention and is not intended to limit the invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of the invention. These improvements and modifications should also be considered within the scope of protection of the invention.
