What are the layers of commonly used plywood hot press machines
In the field of plywood production, the hot press machine is one of the crucial equipment, and the selection of its layers has a significant impact on production efficiency and product quality.
1、 The number of layers in commonly used plywood hot press machines
The commonly used plywood hot press is usually 15 layers. This layer setting has wide applicability in plywood production and can meet most production needs. It performs well in balancing production scale and cost-effectiveness, ensuring a certain output without excessively occupying space and resources.
2、 Composition and characteristics of periodic multi-layer hot press machine
Homework method
The commonly used method in China is the periodic multi-layer hot press machine. It is divided into two types according to the homework method: periodic and continuous. The characteristic of periodic is that its workflow is phased. Complete a series of operations such as loading, pressurization, heating, holding, and depressurization within one work cycle, and then proceed to the next cycle. This method is suitable for the production of plywood in various specifications and batches, and has high flexibility.
component
The periodic multi-layer hot press is composed of three main parts: the hot press body, the control and drive parts (hydraulic system and electronic control system), and the heating system.
The hot press body is the core component for achieving plywood pressing, and its structural stability and accuracy directly affect the quality of plywood. The multi-layered design allows for simultaneous hot pressing treatment of multiple sets of veneers, improving production efficiency.
The hydraulic system provides strong pressure for the hot press machine, ensuring that the veneers can be tightly bonded during the hot pressing process. The electronic control system is responsible for precise control of the entire hot pressing process, including setting and adjusting parameters such as temperature, pressure, and time, to ensure the stability and consistency of the production process.
The heating system is a key part that provides the required heat for hot pressing. Through reasonable heating methods and temperature control, the glue can be fully cured, achieving a firm bonding of the plywood.
Adaptability to different plywood types
Different types of plywood have different requirements for the performance of the press. The pressure requirements for ordinary plywood in production are relatively conventional, and a 15 layer periodic multi-layer hot press can usually meet its production needs well. Due to the special nature of its usage environment, aviation plywood requires extremely high quality and performance, requiring higher pressure and more precise control. After appropriate parameter adjustment and process optimization, this hot press can also be used for the production of aviation plywood, but may require stricter quality monitoring. Due to the characteristics of the material, plastic veneer panels require different temperature and pressure conditions during the hot pressing process, which puts higher demands on the heating system and pressure control system of the hot press machine. However, the periodic multi-layer hot press machine can also adapt to the production of plastic veneer panels through reasonable configuration and adjustment.
The 15 layer periodic multi-layer hot press plays an important role in plywood production. Through a reasonable structure and system composition, it can meet the production needs of various types of plywood, while continuously adapting to the development of the industry and the requirements of product quality improvement, providing reliable equipment support for plywood production enterprises.
