CROSS-REFERENCE TO RELATED APPLICATION AND PRIORITY
[01] The present application claims priority from Indian Patent application no. (201821044043) filed on 22nd November, 2018.

TECHNICAL FIELD
[02] The present subject matter described herein, in general, relates to a rolling machine.
BACKGROUND
[03] Generally, a rolling machine is used for rolling a plate in order to form a cylindrical shape or to form a pipe like structure, when the plate is inserted between rollers. Further, the rolling machine comprises a wheel and a threaded screw. In addition, during operation, the threaded screw may be used to apply pressure on the rollers in order to form the cylindrical shape. This operation is implemented by rotating the wheel that is connected to the threaded screw. Furthermore, the wheel is rotated manually, which leads to increase in wastage of time for checking the movement of roller downwards, increase in number of persons working on the rolling machine, and increase in fatigue of operatives.

[05] In one implementation, a rolling machine is disclosed. In one embodiment, the rolling machine comprises a frame, a primary roller, a pair of secondary rollers, a sprocket wheel, and a primary motor. In one embodiment, the primary roller is coupled to the frame, and the primary roller is distributed axially along a length of the frame. In another embodiment, the pair of secondary rollers are coupled to the frame and are distributed axially along the length of the frame, whereas, pair of secondary rollers are located below the primary roller. In one more embodiment, the sprocket wheel is mounted on the frame. In one aspect, the sprocket wheel comprises a vertical threaded screw. In another aspect, the sprocket wheel is coupled to a gearbox via a chain. In yet another embodiment, the primary motor is coupled to the gearbox.

[06] In one another embodiment, during operation, the primary motor may operate the sprocket wheel via the chain, which in turn operates the vertical threaded screw in order to adjust a pressure on the primary roller, thereby adjusting the pressure on a plate, when the plate is passed through the primary roller and the pair of secondary rollers.

The words "comprising," "having," "containing," and "including," and other forms thereof, are intended to be equivalent in meaning and be open ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items. It must also be noted that as used herein and in the appended claims, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. Although a rolling machine, similar or equivalent to those described herein can be used in the practice or testing of embodiments of the present disclosure, is now described. The disclosed embodiments for the rolling machine is merely example of the disclosure, which may be embodied in various forms.

[11] Various modifications to the embodiment will be readily apparent to those skilled in the art and the generic principles herein may be applied to other embodiments for the rolling machine. However, one of ordinary skill in the art will readily recognize that the present disclosure for the rolling machine is not intended to be limited to the embodiments described, but is to be accorded the widest scope consistent with the principles and features described herein.

[12] Now, referring to Figure 1, Figure 1 illustrates a rolling machine 100. Further, the present subject matter is explained with reference to Figure 1. The rolling machine 100 comprises a frame 102, the frame 102 may be made of steel, iron and the like. The rolling machine 100 further comprises a primary roller 104, a pair of secondary rollers 106, a sprocket wheel 108, and a primary motor 114. In one embodiment, the primary roller 104 is coupled to the frame 102 and is distributed axially along a length of the frame 102. The primary roller 104 may be made of steel, iron and the like. Similarly, the pair of secondary rollers 106 are coupled to the frame 102 and are distributed axially along the length of the frame 102. In one aspect, the pair of secondary rollers 106 are located below the primary roller 104, whereas the primary roller 104 may be at a center of the pair of secondary rollers 106. In another aspect, the pair of secondary rollers 106 are parallel to each other, when distributed along the length of the frame 102.

[13] In yet another aspect, the pair of secondary rollers 106 may be made of steel, iron and the like. In another embodiment, the sprocket wheel 108 may be mounted on the frame 102. In one aspect, the sprocket wheel 108 comprises a vertical threaded screw. In another aspect, the sprocket wheel 108 may be coupled to a gearbox 110 via a chain 112. In one another embodiment, the primary motor may be coupled to the gearbox 110. In one aspect, the primary motor 114 may be coupled to the gearbox 110 via a shaft. In another aspect, the primary motor 114 may be coupled to the gearbox 110 via a chain drive mechanism comprising sprocket wheels at each end of the primary motor 114 and the gearbox 110 respectively. In yet another aspect, the primary moto 114r may be coupled to the gearbox 110 by a belt drive mechanism.

[14] In one another aspect, the primary motor 114 may transmit a drive to the gearbox 110 via a belt drive mechanism. In yet another aspect, the primary motor 114 may be mounted on a platform 116. The platform 116 comprises a bottle screw arrangement 118, whereas the bottle screw arrangement 118 may raise or lower the platform 116 in order to remove the chain 112.

[15] In one implementation, for example, when an operator inserts a plate between the primary roller 104 and the pair of secondary rollers 106, and when the operator turns the switch of the primary motor 114 to “ON”, the primary motor 114 may transmit a drive to the sprocket wheel 108 via the chain 112. In another implementation, the transmitted drive to the sprocket wheel 108 is further transmitted to the vertical threaded screw in order to adjust a pressure on the primary roller 104, thereby adjusting the pressure on the plate. The pressure on the plate may be adjusted by controlling a speed of the primary motor 114.

[16] Similarly, the pressure on the plate may be adjusted at both ends of the frame 102. In one aspect, a pressure measuring scale may mounted on the frame 102 to measure the pressure created on the primary roller 104. In one another implementation, for example, when the operator turns the switch of the secondary motor (not shown) to “ON”, the secondary motor may operate the primary roller 104 and the pair of secondary rollers 106. Thus, the inserted plate may bend to form into a cylindrical shape or a pipe like structure by adjusting the pressure on the plate and by operating or rotating the primary roller 104 and the pair of secondary rollers 106 in clockwise and anti-clock wise direction.

[17] Exemplary embodiments discussed above may provide certain advantages, this may include the following.

[18] Some embodiments of the rolling machine reduces the number of persons working at the rolling machine due to the motor operated sprocket wheel.

[19] Some embodiments of the rolling machine eliminates the fatigue of operatives due to the motor operated sprocket wheel.

[20] Although implementations for the rolling machine 100 have been described in language specific to structural features and/or methods, it is to be understood that the appended claims are not necessarily limited to the specific features or methods described. Rather, the specific features and methods are disclosed as examples of implementation for the rolling machine 100.
