Description:technology
This Invention relates to the field of textile machine technology, particularly to a yarn catching device suitable for textile ring spinning machines
Background technology
Spinning machinery is used to convert fiber raw materials into yarn through different stages and processes. The number of machines operating continuously in the textile factory has increased, resulting in improved productivity. At the end of each stage of the spinning process, various final products are produced, such as fiber clusters, cotton rolls, cotton nets, coarse yarns, and yarns. In the spinning machinery of a textile factory, the purpose of a spinning machine is to stretch the coarse yarn to the desired level, add the required number of twists to the fiber bundle, so that the fibers are combined in the yarn and wound onto the spinning tube. The main purpose of a ring spinning machine is to convert coarse yarn into yarn by inserting twisted yarns to reinforce the yarn. The spinning machinery is equipped with an automatic yarn dropping machine. When the yarn degree wound on the tube (on the spindle) reaches a certain length, the fully wound tube will be replaced by an empty tube. After the tube yarn is wound, the steel ring plate moves vertically from the upper part of the winding area to the bottom of the spindle. The yarn with a full tube of yarn must be fixed and pulled out of the spindle assembly. During the spinning process, certain layers/rolls of yarn are wound at the bottom of the spindle, which is called tube bottom winding. The yarn wound in the bottom winding area of the tube is used to maintain the connection between the wire coil and the spindle, and is also used to continue winding the newly inserted tube after replacing the full tube with an empty tube. When the tube yarn is fully wound and dropped, the yarn needs to be wound at least 1 to 2 layers on the surface of the tube bottom winding at the bottom of the spindle, in order to fix the yarn through known spikes on its surface. When a full tube of yarn is pulled out, the blades on the existing type of yarn cutter will cut the yarn, and each time the full tube of yarn is dropped, it will be wrapped at the bottom of the spindle. The surface should be wrapped/wound with a little yarn
Usually, the bottom winding area of the pipe is made of a rigid metal/non-metal part. A polymer material containing a pointed sleeve was used to capture and fix the yarn. A metal protrusion is installed on the spindle, and the top of the protrusion is equipped with a cutting tool/cutter, which is used to separate the yarn between the bottom winding part of the tube and the full tube yarn. The polymer component used to fix the yarn is circular, with intermittent flat and pointed parts on the circular part. When the polymer component is worn or damaged, the entire ring yarn catcher assembly must be replaced. When replacing the yarn catcher, the geometric shape of the top part of the spindle may be affected, so the entire spindle must be replaced. This replacement process requires the use of specialized loading and unloading tools. The time it takes to replace the spindle is very long

Embodiment
In order to have a clearer understanding of the technical means of the present Invention and to implement it according to the content of the manual, the specific implementation methods of the present Invention are further described in detail below, combined with the drawings and embodiments. The following embodiments are used to illustrate the present Invention, but not to limit the scope of the present Invention
As shown in Figures 1-4, the yarn catching device suitable for textile ring spinning machine in Example 1 includes: spindle 1; A yarn catching component that can move back and forth along the length direction of spindle 1; The yarn catching component includes: a metal protrusion 2 that is movable on the outer wall of the spindle 1; Elastic steel ring 3 installed on the metal convex part 2; And a pointed tip 31 arranged on the elastic steel ring 3 in a circumferential direction; There is a gap 32 on the elastic steel ring 3 for disassembly.
The end of the yarn is fixed on the yarn capture assembly and captured through the yarn capture assembly. When a predetermined length of yarn is wound on the tube yarn, the elastic steel ring 3 moves from the top of spindle 1 to the bottom, where the yarn is wound in the elastic steel ring 3 in the bottom winding section of the tube with polymer components. In the bottom winding area of the tube, the elastic steel ring 3 with a pointed end 31 is used to fix and capture the yarn, thereby maintaining the connection between the wire coil and spindle 1. It is also used to continue winding the newly inserted tube after replacing the full tube yarn with an empty tube
During the assembly process, the elastic steel ring 3 component adheres to the metal convex part 2. When the spinning spool is fully wound and the yarn is dropped, the yarn needs to be wound at least 1.25 times per layer on the pointed surface at the bottom of the spindle 1 to fix the yarn. When a full tube of yarn is pulled out, the tip on the yarn cutter will cut the yarn, and every time the full tube of yarn is dropped, it will be wrapped at the bottom of spindle 1.
By setting the gap 32, when the elastic steel ring 3 is damaged, simple tools or gloved hands can be used to remove the elastic steel ring 3 from the metal protrusion 2 located at the bottom of the spindle 1 through this gap 32. Therefore, the time and cost of replacing the pointed 31 sleeve will be reduced, and no other tools are required for installation and disassembly.
Furthermore, the metal outer protrusion 2 is arranged in a circular shape, and the top of the metal outer protrusion 2 is equipped with a circular connecting piece 21. The connecting piece 21 extends a convex block 22 that is inclined inward, and the connecting piece 21 is equipped with a knife ring 23 that is limited by the convex block 22.
The metal convex part 2 is used to fit on the outer surface of the spindle 1, and then the knife ring 23 is limited by the convex block 22, making it convenient for cutting.
Furthermore, the metal outer protrusion 2 is equipped with a groove 24 for positioning with the spindle 1
Furthermore, the pointed end 31 is integrated with the elastic steel ring 3 for molding.
Furthermore, the elastic steel ring 3 is made of polymer.
The use of rubber polymers can extend the lifespan and reduce costs
Furthermore, the elastic steel ring 3 is bonded to the metal protrusion 2 using adhesive.
