[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model incorporates a lifting mechanism. When encountering leather of varying thicknesses, the operator rotates the hand crank clockwise. The hand crank rotates the connecting column one, which in turn rotates the worm gears on both sides. Simultaneously, the worm gears rotate, causing the threaded rod one to slide upward within the connecting column two, moving the sleeve column upward and thus the grinding shell upward. This allows thicker leather to pass through for grinding. When rotated counterclockwise, the hand crank engages various components, causing the sleeve column to slide downward and the grinding shell to move downward, allowing thinner leather to pass through and be ground. This design achieves precise matching and grinding of leathers of different thicknesses. This flexibility not only broadens the equipment's applicability but also makes it more adept at handling complex and diverse leather products, significantly improving work efficiency.

[0022] 2. This utility model incorporates a moving mechanism. After the leather is polished, the conveyor belt carries the leather into the dust removal area. Motor 2 is activated, driving output shaft 2 to rotate. Output shaft 2 then drives threaded rod 2 to rotate, causing the moving block to move on threaded rod 2 and the moving rod to move on the sliding rod. Simultaneously, the broom moves, sweeping away debris from the leather and directing it into collection bin 1. At the same time, pulley 1 is activated, causing connecting column 5 to drive pulley 3 on the right side to rotate. Pulley 3 then drives belt 2 to rotate, causing connecting column 6 to drive conveyor plate 2 to rotate, allowing debris to fall from collection bin 1 on the right side into the conveyor belt. After being fed into the first collection chamber, the waste is transported to the second collection chamber. The coordinated operation of various components allows the waste from both sides to be transported to the second collection chamber simultaneously. When the equipment stops, the operator pulls out the second collection chamber, which slides along the guide rail, allowing the collected waste to be processed. This design effectively guides the waste from both sides to the second collection chamber simultaneously, preventing waste from scattering or accumulating around the equipment, reducing the complexity and time cost of cleaning, and preventing waste from polluting the working environment, maintaining the cleanliness and safety of the work area, thereby improving work efficiency.
