Description

Technical Field

[0001] This utility model relates to the field of bamboo product processing technology, specifically to a bamboo skewer polishing and finishing mechanism. Background Technology

[0002] Bamboo skewers are slender bamboo sticks widely used in food skewer manufacturing. During bamboo skewer processing, the bamboo is sliced ​​using a slicer, the nodes are removed, and then it is drawn into bamboo strips using a wire drawing machine. Afterward, the bamboo skewers undergo polishing to remove burrs. Polishing refers to the mechanical process of reducing the roughness of a material's surface, making it smoother. Many products require polishing during production, including bamboo and wood products. Traditional bamboo skewer polishing machines place the bamboo skewers inside a cylindrical polishing disc driven by an electric motor. The surface is polished by the skewers rotating, falling, and colliding within the disc. However, existing bamboo skewer processing methods suffer from variations in skewer size, preventing some skewers from making close contact with the polishing structure, thus affecting the polishing quality. Therefore, appropriate dust collection devices should be installed to absorb the dust generated during the polishing process, preventing large amounts of dust from spreading in the production workshop, which is beneficial to employee health and workshop safety. Therefore, in order to improve and optimize processing technology and production environment, and to process bamboo skewer products accurately, efficiently and safely, a device is needed that can polish and finish bamboo skewers.
