The key point in the lamination process is pressure control. The greater the pressure, the better the product quality. The specific requirements are: the pressure rise must be stable, the pressure control accuracy must be high, the constant pressure time must be accurately controlled, and the product pressure must be uniform in all directions. In order to meet the requirements of lamination process and product production, the main design of the equipment should include four parts: loading and unloading system, heating system, pressure system and protection system. Based on the above ideas, the working process of designing the laminator is: 1) Heat the water in the container to reach a certain constant temperature; 2) Load the product, and the sealing head will drop; 3) Set the working pressure and constant pressure time, and Carry out pressure and pressure holding; 4) After the pressure holding is completed, the pressure is automatically released; 5) The sealing pressure head rises and the product is taken out.
