Description

Technical Field

[0001] This utility model relates to the field of edge banding equipment for sheet metal, and in particular to an edge banding machine for sheet metal. Background Technology

[0002] In the furniture manufacturing industry, wood panels and aluminum honeycomb panels are widely used. To achieve a refined and aesthetically pleasing finish, the edges of the panels need to be sealed after processing to conceal the internal structure and achieve a beautiful, dust-proof, and moisture-proof effect. An edge banding machine is a mechanical device that performs edge banding on the panels, automating the traditional manual edge banding process. It is widely used in furniture manufacturing, interior decoration, and wooden door manufacturing industries. The edge banding machine mainly includes processes such as gluing, edge banding, trimming, edge finishing, and polishing. The panels are conveyed by a conveyor belt and pass through all the above processes in one go, ultimately completing the edge banding.

[0003] The adhesive used in the board edge banding machine is hot melt adhesive, which cures quickly. After the board is coated with adhesive and the edge strip is bonded, it can be cured within seconds, allowing for rapid processing of subsequent processes such as trimming, edge trimming, and polishing. However, existing board edge banding machines have problems with uneven adhesive application and insufficient adhesive amount, which can easily lead to weak bonding of the edge banding tape and affect the quality of board edge banding.
