Description

[0001] The invention relates to the technical field of plywood processing, in particular to a grinding device for plywood processing and production. Background Art

[0002] Plywood is one of the commonly used materials for furniture. It is a man-made board. Plywood is a three-layer or multi-layer plate-like material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them together with adhesives. Usually, an odd number of veneers are used, and the fibers of adjacent layers of veneers are glued perpendicular to each other. During the processing of plywood, a polishing process is required to process the board surface and edges to meet quality standards.
