Analysis of Efficient Rotary Cutting Technology of Single-plate Rotary Peeling Machine
As the core equipment of plywood production, veneer spinning machine has high efficient rotary cutting technology which directly determines veneer quality and production efficiency. The current technological breakthrough is mainly reflected in the application of the integration of the spin-free cutting and the numerical control system.
Through the coordinated movement of driving roller and extrusion roller, the non-carding-free rotary cutting technology abandons the traditional carding-shaft structure and enables the wood section to complete the rotary cutting under full pressure. This design not only reduces the diameter of the wood core to less than 40mm, but also significantly improves the wood utilization rate. It also realizes the millimeter-level feed control of the tool rest through the servo motor driving the lead screw, so as to ensure that the thickness error of the single plate is controlled within ± 0.05mm.
The introduction of numerical control system further improves the rotary cutting accuracy. Monitor the diameter change of the wood section in real time through the grating ruler, and the system automatically adjusts the feed speed of the extrusion roller and the angle of the rotary cutter. With the automatic switching function of the hydraulic double clamp shaft, the wood section with the diameter of 500mm to 40mm can be processed continuously. The numerical control rotary cutting machine developed by Weihai Hanwei and other enterprises has achieved the output speed of 30-100m/min. With the self-adaptive adjustment technology of cutter back angle changing with the diameter, the cracks on the back of the veneer are effectively reduced.
Through the collaborative innovation of mechanical structure optimization and intelligent control, the technical system improves the production efficiency by more than 40% while guaranteeing the surface finish of veneer, and provides an efficient and accurate rotary cutting solution for the plywood industry.
