Description

Technical Field

[0001] This utility model relates to the technical field of edge banding equipment for sheet metal, and in particular to a pre-milling device for a small edge banding machine. Background Technology

[0002] In the furniture manufacturing industry, most products use wood panels or compressed boards. 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 edges of wood panels. It automates the traditional manual edge banding process and is widely used in furniture manufacturing, interior decoration, and wooden door manufacturing industries. Existing small edge banding machines generally only have edge banding functionality. For example, the Dongwei series of small edge banding machines, including models DW102, DW702, DWS-210, DW-802, ZX-201, DW770, and XZ-130, etc., will result in poor edge banding effects or even prevent the edge banding operation from being completed when the edges of the panels are uneven or jagged.
