Description

Technical Field

[0001] This utility model relates to the field of dust removal device technology, specifically a dust removal device for furniture sanding. Background Technology

[0002] Sanding plays a crucial role in furniture production, directly impacting the quality of the coating. Firstly, sanding removes burrs, rust, oil, dust, and other impurities from the substrate, laying the foundation for subsequent coating work. Secondly, sanding reduces the roughness of the workpiece's surface to be painted, making the putty-coated surface smoother and improving the mechanical adhesion of the coating. While dust is collected during sanding, some dust adhering to the furniture surface and remaining in crevices requires manual removal by workers. Existing furniture sanding dust removal devices suffer from drawbacks such as inconvenient filter removal and replacement, and difficulty in cleaning dust, making them inconvenient to use. Therefore, this project was developed to address these issues through in-depth research. Utility Model Content
