When the plate needs to be polished, the plate is first placed on the upper end of the base plate 1, and the worm 6 is rotated according to the thickness of the plate, so that the worm wheel 5 and the lead screw 4 rotate. At this time, the slider 8 moves up and down on the outside of the lead screw 4. When the outer surface of the polishing roller 12 contacts the plate, the worm 6 is stopped, and the self-locking function of the worm 6 controls the position of the slider 8 to remain stationary, so that the polishing roller 12 stops moving at the upper end of the plate.

As shown in Figures 1, 2 and 3, the motor 3 is fixedly mounted on the inner side of the slider 8, the outer end of the connecting rod 9 is rotatably connected to the inner side of the lower part of the slider 8, and the inner end of the connecting rod 9 is fixedly connected to the first clamping plate 10, the upper end of the second clamping plate 11 is rotatably connected to the upper end of the first clamping plate 10, and the inner sides of the first clamping plate 10 and the second clamping plate 11 are provided with rectangular grooves, the grinding roller 12 is mounted on the inner sides of the first clamping plate 10 and the second clamping plate 11, and the outer end longitudinal section of the grinding roller 12 is square, the mounting block 13 is fixedly mounted on the lower rear end of the second clamping plate 11, the mounting block 13 is slidably connected to the inner side of the first clamping plate 10, and a through hole is provided inside the mounting block 13, the insertion rod 14 is slidably connected to the inner sides of the first clamping plate 10 and the mounting block 13, the spring 15 is arranged inside the first clamping plate 10, and the two ends of the spring 15 are respectively fixedly connected to the first clamping plate 10 and the insertion rod 14;

When the surface of the grinding roller 12 is worn after the device has been used for a period of time, the rod 14 is pulled downward so that the upper end of the rod 14 slides out of the mounting block 13, and the connection between the rod 14 and the mounting block 13 is released. At this time, the spring 15 is elastically deformed, and the second clamping plate 11 is pulled outward so that the mounting block 13 slides out of the first clamping plate 10, and the grinding roller 12 is removed from the device, and a new grinding roller 12 is placed between the first clamping plate 10 and the second clamping plate 11, and the second clamping plate 11 is lowered to connect the mounting block 13 with the first clamping plate 10 again, and the rod 14 is loosened. Under the elastic action of the spring 15, the rod 14 is reinserted into the mounting block 13 to fix the position of the grinding roller 12, and the motor 3 is turned on. The belt arranged on the outer side of the output end of the motor 3 causes the connecting rod 9 to rotate, thereby driving the grinding roller 12 to rotate, and the plate placed on the upper side of the bottom plate 1 is ground;
