An uncoiling assembly for an aluminum sheet stamping equipment

Abstract

This utility model discloses an uncoiling assembly for an aluminum sheet stamping equipment, relating to the field of machining technology. The solution in this application connects the worm gears on both sides of the support roller via a synchronous shaft, with both worm gears designed to rotate in the same direction. When one worm gear rotates, the synchronous shaft drives both worm gears, worm wheels, and lead screws to rotate synchronously, thereby driving the moving blocks on both sides to rise and fall synchronously along the support plate, structurally preventing the support roller from tilting. This design prevents axial displacement of the aluminum sheet during uncoiling due to roller tilting, reduces scratches caused by friction between the aluminum sheet and the equipment, and reduces creases caused by uneven stress. It also eliminates the need for repeated height calibration, improving adjustment efficiency.

Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to an uncoiling assembly for an aluminum plate stamping equipment. Background Technology

[0002] In existing aluminum sheet uncoiling equipment, the height adjustment of the support rollers often adopts a single-sided independent drive structure (such as single-sided manual screw adjustment or single-sided cylinder drive), or a design with no synchronous linkage between the two sides. Because a single aluminum sheet roll is heavy, single-sided adjustment can easily lead to uneven support heights on both sides, causing the support rollers to tilt and resulting in axial displacement of the aluminum sheet roll during uncoiling. Since aluminum sheets are rigid, this displacement can easily cause scratches due to friction with the equipment edges, or creases due to uneven stress, and in severe cases, even render the aluminum sheet unusable. Even when some equipment uses independent motor drives on both sides, issues such as motor speed differences and transmission clearances often prevent precise synchronous adjustment of the height on both sides. The adjustment process requires repeated calibration, which is time-consuming and labor-intensive, impacting production efficiency. Utility Model Content

[0003] In order to solve the problems existing in the current aluminum plate uncoiling equipment, this utility model provides an uncoiling component for an aluminum plate stamping equipment.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: An unwinding assembly for an aluminum plate stamping equipment is provided, including a frame. An unwinding assembly is provided at one end of the frame. The unwinding assembly includes a support roller. Both ends of the support roller are rotatably mounted on a movable block. The movable block is slidably mounted on a support plate in the vertical direction, and a lead screw passes through the movable block in the vertical direction. The lead screw is threadedly engaged with the movable block. A worm wheel is horizontally provided at the lower end of the lead screw, and the worm wheel is fixedly connected to the lead screw. A worm gear meshing with the worm wheel is provided on the side of the worm wheel. The worm gears on both sides of the support roller are connected by a synchronous shaft. By rotating one side of the worm gear, the lead screws on both sides can be driven to rotate synchronously, thereby driving the movable blocks on both sides to rise or fall synchronously.

[0005] The bottom end of the support plate is slidably mounted on the base plate in the horizontal direction. A through hole is opened on the moving block along the axial direction of the support roller. The end of the support roller is inserted into the through hole through a rotating shaft. The other end of the rotating shaft extends to the outside of the through hole to form an extension section. The rotating shaft and the through hole are slidably engaged in the horizontal direction. The worm gears at both moving blocks are hollow. The synchronous shaft slides through the worm gears at both moving blocks in the horizontal direction. The synchronous shaft and the worm gears form a transmission connection. By rotating one side of the synchronous shaft, the two worm gears can be linked to rotate, thereby driving the worm gears at both moving blocks to rotate synchronously.

[0006] The bottom ends of the support plates on both sides of the support roller pass through a bidirectional screw, which is rotatably connected to the base plate. The support plates on both sides are respectively located on the two threaded sections of the bidirectional screw, and the support plates are threadedly engaged with the bidirectional screw.

[0007] The synchronous shaft is a regular polygonal shaft, and the worm gear has a regular polygonal through hole that matches the regular polygonal shaft. The synchronous shaft achieves a transmission connection with the worm gear through the cooperation between the regular polygonal shaft and the regular polygonal through hole.

[0008] The support plate has a vertical groove, and the two ends of the movable block slide into the groove in the vertical direction. The movable block is slidably installed in the vertical direction with the support plate through the groove.

[0009] The beneficial effects of this utility model are as follows:

[0010] The worm gears on both sides of the support roller are connected by a synchronous shaft, with both worm gears rotating in the same direction. When one worm gear rotates, the synchronous shaft drives both worm gears, worm wheels, and lead screws to rotate synchronously, thereby driving the moving blocks on both sides to rise and fall synchronously along the support plate. This structural design prevents the support roller from tilting. This design prevents axial displacement of the aluminum sheet during unwinding due to roller tilting, reduces scratches caused by friction between the aluminum sheet and the equipment, and reduces creases caused by uneven stress. It also eliminates the need for repeated height calibration, improving adjustment efficiency. Attached Figure Description

[0015] The present application will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can better understand and implement the present invention, but the embodiments described are not intended to limit the present invention.

[0016] Example: Figures 1 to 4As shown, an unwinding assembly of an aluminum plate stamping equipment includes a frame 100. An unwinding assembly 200 is provided at one end of the frame 100. The unwinding assembly 200 includes a support roller 300. The two ends of the support roller 300 are respectively rotatably mounted on a movable block 301. The movable block 301 is slidably mounted on a support plate 302 in the vertical direction, and a lead screw 303 passes through the movable block 301 in the vertical direction. The lead screw 303 is threadedly engaged with the movable block 301. A worm gear 304 is horizontally provided at the lower end of the lead screw 303. The worm gear 304 is fixedly connected to the lead screw 303. A worm 305 is provided on the side of the worm gear 304 for meshing and transmission. The worms 305 on both sides of the support roller 300 are connected by a synchronous shaft 306. By rotating one side of the worm 305, the lead screws 303 on both sides can be driven to rotate synchronously, thereby driving the movable blocks 301 on both sides to rise or fall synchronously.

[0017] In this embodiment, one end of the frame 100 is reserved with an installation space for the unwinding assembly 200. The support roller 300 is horizontally arranged in the installation space to support the roll material (aluminum plate roll material) to be unwound. The support roller 300 can rotate around its own axis to realize the unwinding action of the roll material.

[0018] Both ends of the support roller 300 are connected to the movable block 301 through a rotating connection structure (such as a bearing) to ensure that the support roller 300 can rotate flexibly relative to the movable block 301. The movable block 301 is slidably mounted on the support plate 302 in the vertical direction. Specifically, a strip groove is provided on the inner side wall of the support plate 302 in the vertical direction. The movable block 301 is inserted into the groove and can slide along the length of the groove. Through the cooperation of the groove and the slider, the movable block 301 is restricted to move only in the vertical direction to avoid the movable block 301 from shifting in the horizontal direction.

[0019] Each movable block 301 has a threaded hole in the middle along the vertical direction. A lead screw 303 passes vertically through the threaded hole and forms a threaded engagement with the threaded hole. When the lead screw 303 rotates, the movable block 301 can be driven to rise or fall along the axis of the lead screw 303 (i.e., the vertical direction) through the threaded transmission action, thereby realizing the adjustment of the height of the support roller 300.

[0020] Specifically, the worm gears 305 on both sides must rotate in the same direction to ensure synchronous driving of the lead screw 303 to raise and lower the moving block 301. Simultaneously, the worm wheel 304 and worm gear 305 must be self-locking to prevent the support roller 300 from sinking due to the heavy pressure of the aluminum sheet coil. It is preferable that both worm gears 305 and lead screw 303 on both sides are right-handed. Rotating the right worm gear 305 clockwise (viewed from the end) causes the worm wheel 304 to drive the lead screw 303 clockwise, raising the moving block 301. Reversing the rotation lowers it, and both sides must rotate synchronously.

[0021] The bottom end of the support plate 302 is slidably mounted on the base plate in the horizontal direction. The moving block 301 has a through hole 307 along the axial direction of the support roller 300. The end of the support roller 300 is inserted into the through hole 307 through a rotating shaft 308. The other end of the rotating shaft 308 extends to the outside of the through hole 307 to form an extension section. The rotating shaft 308 and the through hole 307 are slidably engaged in the horizontal direction. The worm gears 305 at both moving blocks 301 are hollow. The synchronous shaft 306 slides through the worm gears 305 at both moving blocks 301 in the horizontal direction. The synchronous shaft 306 and the worm gears 305 form a transmission connection. By rotating one side of the synchronous shaft 306, the two worm gears 305 can be rotated in tandem to drive the worm gears 305 at both moving blocks 301 to rotate synchronously.

[0022] The bottom ends of the support plates 302 on both sides of the support roller 300 pass through a bidirectional screw. The bidirectional screw is rotatably connected to the base plate. The support plates 302 on both sides are respectively located on the two threaded sections of the bidirectional screw, and the support plates 302 are threadedly engaged with the bidirectional screw.

[0023] The synchronous shaft 306 is a regular polygonal shaft, and the worm gear 305 has a regular polygonal through hole 307 that is adapted to the regular polygonal shaft. The synchronous shaft 306 achieves a transmission connection with the worm gear 305 through the cooperation between the regular polygonal shaft and the regular polygonal through hole 307.

[0024] To achieve synchronous rotation of the lead screws 303 on both sides, the worms 305 on both sides of the support roller 300 are connected by a synchronous shaft 306. In this embodiment, the synchronous shaft 306 is a regular polygonal shaft (such as a regular hexagonal shaft). Correspondingly, the ends of the worms 305 on both sides are hollow, and the hollow holes of the worms 305 are regular polygonal through holes 307 that are adapted to the regular polygonal shaft. The two ends of the synchronous shaft 306 are respectively inserted into the regular polygonal through holes 307 of the worms 305 on both sides. Through the shape matching of the regular polygonal shaft and the regular polygonal through holes 307, it is ensured that there is no relative rotation between the synchronous shaft 306 and the worms 305. That is, when the synchronous shaft 306 rotates, it can drive the worms 305 on both sides to rotate synchronously. At the same time, the regular polygonal matching structure of the synchronous shaft 306 and the worms 305 also allows the synchronous shaft 306 to slide relative to the worms 305 along its own axial direction, reserving movement space for the subsequent horizontal adjustment of the support plate 302.

[0025] When the height of the support roller 300 needs to be adjusted, the operator can drive one side of the worm gear 305 (or directly drive the synchronous shaft 306) to rotate using a wrench or motor. Due to the synchronous transmission effect of the synchronous shaft 306, the two worm gears 305 will rotate synchronously, which in turn drives the two worm wheels 304 and the lead screw 303 to rotate synchronously. Ultimately, the two moving blocks 301 on both sides will rise or fall synchronously, ensuring that the support roller 300 remains horizontal during the height adjustment process and avoiding the unwinding deviation of the roll material due to the inconsistent height on both sides.

[0026] The support plate 302 has a sliding groove along the vertical direction. The two ends of the moving block 301 slide into the sliding groove along the vertical direction. The moving block 301 is slidably installed with the support plate 302 along the vertical direction through the sliding groove.

[0027] In one possible implementation, a horizontal base plate is fixedly installed at the bottom of the frame 100. The upper surface of the base plate is provided with a guide groove along the axial direction (i.e., horizontal direction) of the support roller 300. The bottom ends of the support plates 302 on both sides of the support roller 300 are slidably engaged with the guide groove by sliders to ensure that the support plates 302 can slide along the length direction (horizontal direction) of the guide groove. A bidirectional screw is horizontally set on the base plate. The two ends of the bidirectional screw are rotatably connected to the base plate through bearing seats. Two sections of external threads with opposite directions of rotation are machined on the body of the bidirectional screw (i.e., the left thread section and the right thread section have opposite directions of rotation).

[0028] Both sides of the support plate 302 have threaded holes at their bottom ends that are adapted to the bidirectional screw. The bidirectional screw passes through the threaded holes of the two support plates 302. The left support plate 302 is engaged with the left threaded section of the bidirectional screw, and the right support plate 302 is engaged with the right threaded section of the bidirectional screw. When the bidirectional screw is rotated, since the two threads rotate in opposite directions, the two support plates 302 will move towards or away from each other along the axis of the bidirectional screw, thereby adjusting the distance between the two support plates 302 to accommodate the installation requirements of support rollers 300 of different widths.

[0029] When the distance between the two support plates 302 is adjusted, the rotating shafts 308 at both ends of the support roller 300 will slide horizontally along the through holes 307 on the moving block 301 (the through holes 307 on the moving block 301 are opened along the axial direction of the support roller 300, the rotating shaft 308 and the through holes 307 are in clearance fit, and the extension of the rotating shaft 308 extending out of the through holes 307 can slide synchronously with the movement of the support plate 302). At the same time, the synchronous shaft 306 will slide horizontally along the regular polygonal through hole 307 of the worm 305, ensuring that the meshing relationship of the worm wheel 304 and the worm 305 and the synchronous transmission relationship of the synchronous shaft 306 are not affected during the horizontal adjustment of the support plate 302.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
