Description
TECHNICAL FIELD
[0001] The utility model relates to plywood manufacturing field, concretely is plywood production is used sanding device. BACKGROUND
[0002] Plywood is composed of multiple thin wood veneer layers, which are usually rotary cut or sliced from logs. The thickness of each veneer layer is usually between 1-3 millimeters, and the number of layers of the plywood is usually odd, such as 3 layers, 5 layers, 7 layers, etc. This is to make the plywood have a symmetrical structure, thereby enhancing its stability and bending strength. The fiber direction of each veneer layer is usually perpendicular to each other, and then they are bonded together using synthetic resin adhesive. Hot pressing is carried out under high temperature and high pressure to make the adhesive solidify and the veneers firmly bonded into a whole.
[0003] During the manufacturing process of the plywood, the thickness and surface of each veneer layer may not be uniform, resulting in uneven and concave-convex board surface, which causes the overall quality of the plywood to deteriorate. At the same time, some impurities, burrs or glue residues may be left on the surface of the plywood, which reduces the aesthetic appearance. SUMMARY
