Technical Field

[0001] The utility model relates to the technical field of plywood processing, in particular to an edge grinding device for plywood production. Background Art

[0002] Plywood is a three-layer or multi-layer board made of veneer or thin wood bonded by adhesive. It is made by criss-crossing the veneer coated with glue in the direction of the wood grain to form a slab, which is pressed under heating or unheating conditions. It has a wide range of uses and is mostly used as material for aircraft, ships, trains, cars, buildings and packaging boxes. When producing plywood, it is usually necessary to grind the edges of the board.

[0003] According to patent number CN 216179196 U, a plywood production edge grinding device is disclosed, which relates to the field of plywood.

In addition, when the fixing clamp moves on the surface of the plywood, it may cause a certain degree of scratches on the surface of the plywood, thereby affecting the smoothness and beauty of the surface of the plywood. Therefore, the technical scheme needs to be improved. Utility Model Content
