Veneer hot press is a kind of equipment commonly used for processing wood, wood-based board and other materials, its main function is to glue materials and plates together under high temperature and high pressure conditions. In order to ensure the quality and effect of the veneer process, it is necessary to adjust and control the pressure of the hot press. The following are several common pressure adjustment methods of veneer hot press:

1. Manual adjustment: Manual adjustment is one of the basic pressure adjustment methods, by manually rotating the regulator or pressing the button to change the working pressure of the hydraulic system. This method is simple to operate, but requires constant human monitoring and adjustments as needed.

2. Controller adjustment: The veneer hot press is often equipped with PID controller. By setting the expected pressure value and control parameters, the controller will adjust the hydraulic system according to the real-time pressure signal to keep it within the set range. This method has the characteristics of high automation and good stability, and can improve the production efficiency and veneer quality of the hot press.

3. Pressure sensor feedback: Pressure sensors can be installed on the veneer hot press to monitor the working pressure of the machine in real time, and adjust the pressure through the feedback control system. When the pressure deviates from the set value, the control system will automatically adjust the working state of the hot press to keep it within the set pressure range. This method has the advantages of fast response speed and small error, and can achieve more accurate pressure control.

4. Hydraulic system adjustment: The hydraulic system of the veneer hot press has a certain adjustment range, and the output pressure of the hydraulic system can be changed by adjusting the working parameters of the hydraulic system, such as the displacement of the hydraulic pump and the piston area of the hydraulic cylinder. In this way, the pressure can be adjusted by adjusting the hardware structure of the hydraulic system, but the working principle and parameters of the hydraulic system need to have a certain understanding.

5. Mechanical structure adjustment: The mechanical structure of the veneer hot press can also be used to adjust the pressure of the hot press. For example, by adjusting the distance between the upper and lower heating plates, adjusting the thickness of the heating plate, etc., the pressure of the plate can be changed during the veneer process. This method is relatively simple, but it requires a certain understanding of the mechanical structure of the veneer hot press and operational experience.

The above are several common pressure adjustment methods of veneer hot press. According to the different models and actual needs of the veneer hot press, the appropriate pressure adjustment mode can be selected to achieve the accurate control of the pressure during the veneer process.
