Description
TECHNICAL FIELD
[0001] The utility model relates to wood processing machinery technical field, concretely is a wooden board polishing device. BACKGROUND
[0002] In the wood board processing industry, polishing is a key process, and its purpose is to make the board surface smooth and flat to meet various production needs and quality standards. At present, the common polishing method is to manually hold a polisher to operate on the wooden board. The polisher is provided with a detachable polishing disc, and the polishing effect is achieved by high-speed friction between the polishing disc and the wood surface.
[0003] As a consumable directly acting on the wood, the polishing disc inevitably wears out due to frequent contact with the wood surface, frictional heat generation and other factors during continuous polishing. As the polishing time increases, the degree of wear of the polishing disc gradually increases, and the polishing efficiency and quality will decrease significantly, thereby affecting the polishing effect of the entire board. In order to ensure the smooth progress of the polishing work and the stability of the polishing quality, the polishing disc on the polisher must be replaced after a period of polishing.
[0004] However, it is found in actual production that the replacement frequency of the existing polishing disc is too high. This not only leads to a substantial increase in labor costs, because frequent replacement of the polishing disc requires the operator to interrupt the normal polishing work process, consuming additional time and effort; and frequent replacement of the polishing disc also reduces production efficiency.
