Description

Technical Field

[0001] This utility model relates to a sanding device for plywood production, belonging to the technical field of sanding equipment for plywood production. Background Technology

[0002] During the production and processing of plywood, burrs are present on the surface of the boards. In order to achieve a high degree of surface smoothness, the surface of the plywood generally needs to be sanded to remove the burrs. When removing burrs from some smaller plywood boards, a grinding wheel is used.

[0003] Many existing factories use manual grinding wheels to polish the surface of plates. This method is flexible and allows for targeted polishing of specific areas. However, manual polishing often involves placing the plates directly on a platform, which generates a lot of dust, pollutes the environment, and can harm the health of polishing workers in the long run. Placing industrial fans on-site is not effective and can also cause dust to spread.

[0004] Therefore, this utility model proposes a new solution. Utility Model Content
