The structural system of the high-speed extrusion laminator mainly includes four parts: loading and unloading system, heating system, pressure system and protection system. The heating system consists of a measuring element, a controller, and a heater. Its function is to heat and control the water in the container, and the heat is evenly heated by water conduction.
The heating element of the high-speed extrusion laminator is a stainless steel electric heating plate wrapped around the outer surface of the sealed container. After the electric current is applied, the electric heating plate generates heat, and the heat is transferred to the water in the container to raise the temperature. In practice, in order to ensure that the water temperature can meet the process requirements, it is usually heated before feeding, and the water temperature is directly measured by a temperature detecting instrument.
The container is in a high-pressure sealed state during operation, and the water temperature can only be measured and controlled by an intelligent digital display temperature controller. The temperature measuring component cannot directly measure the temperature of the liquid in the container, and only indirect measurement is adopted. Therefore, it is required to reduce the measurement error and the control lag in the selection and installation of the component.
The pressure system of the high-speed extrusion laminator consists of a pressure transmitter, a pressure control instrument, a booster pump, a manual valve, a pneumatic valve, and the like. Its function is mainly: the pressure transmitter detects the pressure in the sealed container, converts the pressure value into a standard signal of 4~20 mA, and transmits it to the signal input end of the pressure control instrument.
