[0003] For example, the national patent publication number CN214361459U discloses a new type of leather-specific polishing device, including a conveying operation table, the top of the conveying operation table is fixedly connected to a polishing box, the bottom of the two side surfaces of the polishing box is provided with an inlet and outlet, and the top of the inner cavity of the conveying operation table is fixedly connected to a slide rail. Through the mutual cooperation between the designed polishing box, inlet and outlet, slide rail, stepper motor, electric telescopic rod, polishing motor, motor output shaft, polishing tool and other structures, the reinforced leather can be delivered to the surface of the conveying operation table, and then the leather can be polished quickly and effectively, which improves the working efficiency of the equipment for leather polishing, increases the use effect and practical performance of the equipment, and effectively solves the problem that when the existing equipment is working, the operator needs to manually transport the leather to the inside of the polishing equipment, which reduces the working efficiency of the equipment.

At the same time, the present invention installs a limited tooth groove 38 on the connecting blade 16. When the connecting blade 16 rotates to generate flowing wind, the high-speed moving limited tooth groove 38 will also magnetically attract the passing connecting magnet 2 39, so that the connecting magnet 2 39 drives the extension plate 21 to vibrate. The plate 21 is shaken at a high frequency, and the shaking of the connecting magnet 2 39 further increases the vibration frequency of the grinding wheel 25, thereby improving the polishing effect and work efficiency of the device. In the present invention, while the vertical motor 7 drives the polishing device to and fro, the connecting gear 35 will mesh and rotate on the outer wall of 37, and the connecting gear 35 and the threaded rod 34 will rotate synchronously. The meshing connection of the threaded groove 36 and the threaded rod 34 allows the limit bearing 26 to move back and forth, thereby driving the end of the limit support frame 19 to be pressed down, so that the limit support frame 19 can be opened and closed and retracted to the surface of the mounting sleeve 10, and the opening and closing of the limit support frame 19 can increase the moving range of the grinding wheel 25, thereby further improving the polishing effect and work efficiency of the device.
