AI Technical Summary

Technical Problem

Existing technologies rely on manual sanding, which is inefficient and cannot flexibly switch between coarse and fine sanding processes when processing wood products with curved surfaces or arcs.

Method used

It adopts a double-sided polishing structure, combined with an air pressure adjustment component and a coarse-fine switching structure. The airbag carries the polishing belt to fit closely to the surface of the wood product, and the rotation direction of the polishing belt is changed by a gear combination, so as to achieve flexible polishing of curved and flat surfaces.

Benefits of technology

It achieves efficient grinding of curved and flat surfaces, and can automatically adjust the tension and rotation direction of the grinding and polishing belt, improving grinding efficiency and flexibility and reducing manual intervention.
