[0001] The utility model belongs to the technical field of plywood processing, and in particular relates to a device for removing burrs from the surface of plywood. Background Art

[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesive. It usually uses an odd number of veneers, and glues the fibers of adjacent veneers perpendicular to each other. Plywood is one of the commonly used materials for furniture, one of the three major artificial boards, and can also be used as material for airplanes, ships, trains, cars, buildings, and packaging boxes. A group of veneers is usually assembled and glued in such a way that the grain directions of adjacent layers are perpendicular to each other. Usually, the surface board and the inner layer board are symmetrically arranged on both sides of the center layer or the core.

[0003] In the production process of plywood, it is usually necessary to remove burrs on the surface of the plywood. However, in the prior art, the burr removal device can usually only grind and remove burrs on plywood of one size, and the burr removal device cannot be adjusted according to the size of the plywood, so the scope of use is limited.
