How to ensure accuracy in the production process of plywood machinery
The production of plywood requires strict indicators such as board thickness, flatness, and bonding strength, and the precision of mechanical processing directly affects product quality. To ensure production stability, it is necessary to systematically control accuracy from three aspects: equipment, process, and operation
1、 Equipment precision maintenance
Regular calibration: Regularly calibrate the pressure sensors, temperature controllers, and thickness gauges of core equipment such as hot press machines and rotary cutting machines to ensure parameter errors of ≤± 0.1mm.
Key component maintenance: Daily inspection of tool wear and timely replacement of passivated blades; Regularly lubricate the transmission chain and guide rail to reduce the impact of mechanical vibration on machining accuracy.
2、 Optimization of process parameters
Dynamic adjustment: Real time adjustment of hot pressing temperature (120-150 ℃) and pressure (1.5-2.5MPa) based on wood moisture content (8% -12%) and veneer thickness (0.8-3mm) to avoid deformation of the board due to parameter deviations.
Closed loop control: Introducing a laser positioning system in processes such as edge cutting and sanding, providing real-time feedback on dimensional data and automatically correcting deviations to control thickness tolerances within ± 0.05mm.
3、 Standardized operation management
Develop equipment operating procedures and require operators to undergo training before taking up their posts to reduce human errors. Through the above measures, stable precision can be achieved throughout the entire production process of plywood, and the product qualification rate can be improved to over 98%.
