PE film blower extruder is mainly composed of screw, barrel feeding hopper, deceleration and drive motor. The drive motor adopts electromagnetic speed regulating motor (or frequency conversion common motor), which drives the screw to rotate in the barrel through belt drive, and melts plastic particles in the hopper under external heating. The three way filter is extruded from the die mouth, and consists of three parts: filter screen, filter plate and three way gland.
Cooling device consists of cooling air ring, air duct, blower and so on; traction is composed of traction frame, herringbone, traction roll, coiling mechanism and traction motor; electrical control part, general unit is equipped with unit operating cabinet, which is controlled by the main button to press the main power supply and turn on the main switch of the motor, respectively, through the button switch. The fuselage and three links, each button of the mouth die.
The key part of the two coils is thermocouple automatic temperature measurement and automatic temperature control. In normal production process, the temperature can be automatically controlled to ensure that the production process is stable and reliable. Take Guoyan Brand PP film blower as an example: the barrel and screw of extruder are made of high quality alloy steel, which has good hardness and corrosion resistance after nitriding and precision processing.
