Technical Field

[0001] The utility model relates to the field of wood processing, in particular to a grinding and polishing device for wood processing. Background Art

[0002] The polishing process in wood processing is a very important step, which is directly related to the surface quality and appearance of wood products. Polishing can not only remove burrs and defects on the surface of wood, but also improve the texture and appearance of wood. According to different needs and processing stages, wood polishing can adopt a variety of methods and tools.

[0003] The existing wood grinding and polishing devices often have fixed grinding structures, so when facing wood of different specifications, the grinding ability is often greatly reduced, and the fixation of the grinding structure will also affect its grinding efficiency. Because the grinding structure is fixed in one place, when grinding, it is often necessary to repeatedly grind the poorly polished wood, which in turn affects the grinding effect and grinding efficiency of the grinding device.

By adding a reciprocating displacement structure and an elastic-assisted clamping structure to the grinding device, the device can achieve the effect of efficiently grinding wood of different specifications.
