[0036] The working principle of the utility model is as follows: when in use, according to the thickness of the metal plate, start the reduction motor 61, drive the adjusting screw 54 to rotate, adjust the height of the conveyor belt 5, and then put the metal plate on the conveyor belt 5, so that the conveyor belt 5 transports the plate to the bottom of the sanding belt 4, and the driving motor 41 drives the active roller 2 to rotate, so that the sanding belt 4 grinds and polishes the top surface of the plate. When the sanding belt 4 is severely worn and needs to be replaced, rotate the support tube 24 to make it rise, then retract the electric push rod 32, and lower the driven roller 3, so that the sanding belt 4 can be easily taken out from the gap between the support tube 24 and the support plate 25, and then install the new sanding belt 4 on the surface of the active roller 2 and the driven roller 3, extend the electric push rod 32, raise the driven roller 3, and tighten the sanding belt 4.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The support rod 33 supports the driven roller 3 through the electric push rod 32 and the U-shaped frame 31. The support rod 33 supports one end of the active roller 2 through the support seat 22. Therefore, one end of the active roller 2 and the driven roller 3 is in a suspended state, and cooperates with the electric push rod 32. When replacing the sanding belt 4, the electric push rod 32 is retracted, the driven roller 3 is lowered, and the sanding belt 4 will be loosened. Then, the sanding belt 4 is taken out from one side, and a new sanding belt 4 is put on the surface of the active roller 2 and the driven roller 3. The electric push rod 32 is extended, and the new sanding belt 4 is tightened to complete the replacement. The operation is simple and saves time and effort.

[0039] 2. By setting a support screw 23 at the bottom of one end of the support rod 33, and threading the support tube 24 on the outer surface of the support screw 23, the support tube 24 is rotated to lower it, and the bottom contacts the support plate 25, so that the end of the support rod 33 can be supported, which can reinforce the support rod 33 and avoid the problem of breakage at the connection between it and the frame 1. The reliability of the structure is ensured without affecting the easy disassembly of the sanding belt 4.

[0040] 3. By starting the reduction motor 61 and driving the adjusting screw 54 to rotate, the lifting plate 53 can be raised or lowered. Therefore, the lifting plate 53 can drive the conveyor belt 5 to be raised or lowered through the lifting rod 52, thereby achieving the purpose of adjusting the distance between the conveyor belt 5 and the sanding belt 4. Therefore, it can be suitable for grinding plates of different thicknesses, thereby improving practicality.
