The upper surface of the workbench is concave downward to form a first slide groove and a second slide groove that are parallel to each other, and the first slide groove and the second slide groove are respectively provided with a clamping plate. A knife groove is also provided through the workbench, and the cutting knife is provided in the knife groove. The plane where the cutting knife is located is parallel to the length direction of the first slide groove, and the cutting knife extends out of the upper surface of the workbench. The cutting knife is also connected to a driving mechanism; a clamping groove is formed on the clamping plate, and the plate to be cut is placed between the clamping groove and the cutting knife. A threaded rod is also provided on the clamping plate, and the threaded rod is screwed into the clamping plate in the vertical direction, and the lower end of the threaded rod is to the clamping groove. The plate cutting machine overcomes the problem in the prior art that the plate is offset at the cutting position, resulting in processing failure, and because the texture of the plate is hard, the plate is prone to shaking, affecting the accuracy of plate cutting.

[0004] However, when the existing plywood is cut, the flying wood chips easily enter the eyes and mouth of the personnel, resulting in low safety during the operation; therefore, it does not meet the existing needs. In this regard, we propose a plywood processing and cutting protective device. Utility Model Content
