ABA film blower is widely used in blowing high and low pressure polyethylene. The products are widely used in composite film, packaging film, agricultural covering film, textiles, clothing bags or film packaging. The main motor adopts frequency conversion speed regulation, which increases the stability of speed regulation of the main engine and saves 30% electricity. The screw barrel adopts 38 chromium molybdenum and aluminium. After nitriding treatment, the tractor rack adopts lifting. No matter big or small size film, the cooling effect can be better.
Traction auxiliary machine: traction frame, herringbone splint, traction roll (2-3), transmission shaft, winding roll and other components. Driven by traction motor, the extruded tubular film is pulled up and stretched through herringbone splint, traction roll, transmission roll to the roll and then rolled into a film drum. All parts are equipped with adjusting devices for adjustment when used.
The upper and lower two parts are assisted by air inlet pipes and fans. The fan feeds the air into the air duct and the air ring, blows the cold air evenly to the outlet of the die, and cools the tubular bad film. The air ring has an adjusting device to adjust the air volume. The temperature of the main engine is adjusted by electric heating, and the temperature is controlled by an automatic control instrument. It depends on the type, performance, plasticizing index of the raw material and the speed of the whole machine. The adjustment of the temperature of the main engine is usually gradually increased from the feed port to the three pass, and the temperature of the die is slightly lower than that of the three one.
