[0002] When producing furniture, the boards used need to be ground and polished to make their surfaces smooth and shiny, and the defects of the boards need to be modified and concealed to enhance the beauty of the furniture.
[0003] Nowadays, furniture is often polished by driving polishing rollers. Commonly used polishing rollers are mostly provided with abrasives on the surface, or sandpaper is wrapped around the surface to polish furniture. When the polishing roller is polished by setting abrasives on the surface, the abrasives are consumed with use, resulting in a decrease in the polishing effect, and the polishing roller needs to be replaced, resulting in a high cost of use. When sandpaper is wrapped around the roller for polishing, the sandpaper is usually pasted on the roller, and after the sandpaper is consumed with use, only the sandpaper is replaced, thereby reducing the cost of use. However, due to the unstable fixation of the sandpaper, the sandpaper becomes loose and displaced during the polishing process, which affects the polishing efficiency and polishing effect, and the replacement of the sandpaper is inconvenient.
[0004] At the same time, during the grinding and polishing process, the floating dust generated during the grinding process will adhere to the surface of the polishing roller. The floating dust will contact the surface of the plate as the polishing roller runs, thereby affecting the grinding and polishing effect of the polishing roller. Utility Model Content
