[0002] Plywood is a board made of multiple layers of thin wood boards glued together. It has excellent performance and a wide range of uses. These veneers are usually sliced ​​into thin sheets from wood segments or planed into veneers from wood blocks, and then dried. During the manufacturing process, these veneers are stacked in a certain order, and usually the fiber directions of adjacent layers are perpendicular to each other to enhance the strength and stability of the board.

[0003] The existing plywood conveying is to place the plywood on a conveyor belt for various conveying processes. When the plywood after heat processing is cooled, uneven cooling may occur. The plywood may cause local bulges due to thermal stress, thereby affecting the production quality of the plywood, which is relatively inconvenient.

[0004] Therefore, it is necessary to design a plywood conveying and leveling auxiliary device that can locally level the plywood during conveying, ensure that the plywood remains flat during conveying, and ensure the production quality of the plywood. Utility Model Content
