[0012] Beneficial effects of the utility model:

[0013] 1. Compared with traditional polishing devices, the surface area of ​​the material used for polishing is smaller, which is easily worn out during use and affects its use. It needs to be replaced frequently, which not only wastes working time, but also causes differences in the surface finish of the same batch or even the same polishing rod, which affects the use of the cylinder and reduces the service life of the cylinder. By increasing the surface area of ​​the polishing material, the polishing material can be used for a longer time, the number of replacements can be reduced, and the waste of working time can be reduced;

[0014] 2. During polishing, the rotating motor drives the clamping block to rotate, so that the workpiece rotates. At the same time, the belt-discharging motor drives the belt-discharging roller to rotate, and the belt-receiving motor drives the belt-receiving roller to rotate, so that the sandpaper belt moves. The moving sandpaper belt polishes the rotating workpiece surface. The transverse motor drives the transverse threaded rod to make the threaded seat move smoothly with the cooperation of the transverse slider, driving the sandpaper belt to move and polish the surface of the workpiece. In this process, since the surface area of ​​the sandpaper belt that can be used for polishing is large, the number of polishing times per unit area is small, and the wear is also small. A roll of sandpaper belt can be used for a long time, so as to solve the problem that the surface area of ​​the material used for polishing in most polishing devices is small, it is easy to be worn during use, and needs to be replaced frequently, thereby enhancing the practical value of the device;

[0015] 3. Before polishing, the fixed motor drives the fixed threaded rod to rotate. The threads at both ends of the fixed threaded rod are divided into left-handed and right-handed, driving the two sets of brackets to approach each other, thereby driving the clamping block and the rotating motor to move, and adjusting the spacing between the two sets of clamping blocks so that the clamping block fixes the workpiece. The transverse motor drives the transverse threaded rod to make the transverse sliding block slide in the transverse sliding groove, driving the threaded seat to move smoothly, and moving the sandpaper belt to one end of the workpiece. The adjusting motor drives the adjusting threaded rod to rotate, making the adjusting slider slide in the adjusting groove, driving the threaded seat to move smoothly, thereby driving the support rod and the mounting frame to move, and then driving the polishing roller and the sandpaper belt to move, so that the sandpaper belt is close to the surface of the workpiece.
