The die of ABA film blower is covered from top to bottom. That is to say, loosen the screw when it is thicker. This is called an in-line die head. If there is a big mouth below and the top die is put in, it is to loosen the thin side and tighten the thick side. This is called reverse adjustment.


There are four or six adjusting bolts in the die head, which are usually hexagonal. At the upper edge of the die, they can be adjusted. As for the tightness or looseness, different moulds from different origins are different, it is necessary to know after operation. Clean the head and spirochete, use paraffin or methyl silicone oil to smear when cleaning, and then gently wipe the paste with 1000 mesh sandpaper until clean.


When changing material, the temperature should be adjusted according to material property (there is difference between return material and pure material temperature). After changing mesh, the extrusion quantity should be increased to extrude paste. The main structure of film blower is mainly composed of extruder, die, cooling device, foam stabilizer, herringbone, traction roll and coiling device. 1. Extruder is mainly composed of screw, barrel feeding hopper, deceleration and driving motor. The driving motor adopts electromagnetic speed regulating motor (also can use frequency conversion ordinary motor).


The belt drive reducer drives the screw to rotate in the barrel; the plastic melted in the hopper under external heating is extruded 2:3 through three filters from the die mouth; the three parts of the filter screen, the filter plate and the three-way pressure cover are composed of 3:4:cooling device; the cooling air ring, the air duct, the blower, etc. are composed of 5:traction, and the traction frame, the herringbone plate and the traction roll.
