Machine work in plywood manufacturing process
Plywood manufacturing is a key link in the field of wood processing, and its process relies on the precise coordination of multiple machines. After the logs are cut into appropriate lengths by the wood cutting machine, the rotary cutting machine cuts the wood into uniform veneers. This process requires precise control of the tool angle and feed speed to ensure uniform veneer thickness and clear texture.
In the drying process, the automated drying equipment uses a hot air circulation system to reduce the moisture content of the veneer to the process standard within 7 to 10 minutes, avoiding subsequent deformation. The gluing process adopts a 48 foot gluing machine, which achieves uniform distribution of glue solution through precision measuring devices. The adjustable spacing between rubber rollers ensures stable gluing amount for different thicknesses of veneer.
The assembly process is completed by an automatic board arranging line, and the mechanical arm arranges the veneers in a criss cross pattern according to the wood grain direction, forming a stable laminated structure. The cold press machine pre presses with a pressure of 400 to 500 tons to preliminarily solidify the adhesive layer and prevent misplacement during transportation. As the core equipment, the hot press machine fully solidifies the adhesive at a high temperature of 120 ℃ to 150 ℃ and a specific pressure, forming a high-strength bond.
The subsequent sanding machine gradually eliminates the unevenness on the surface of the board through a combination of multi-stage sanding belts, and finally the edge cutting machine completes the size shaping. Throughout the entire production process, each machine is controlled by a PLC system to achieve parameter linkage, ensuring product dimensional accuracy of ± 0.5mm and adhesive strength in accordance with national standards.
