大連ABA film blowing machine

Film blowing machine manufacturers mainly produce various PE film blowing machines, three-layer coextrusion film blowing machines, ABA film blowing machines, various multi-layer coextrusion composite film units, etc. It has strong technical force, perfect management and product quality assurance system. Welcome to inquire. This group is suitable for blowing low density polyethylene (LDPE), high density polyethylene (HDPE) and linear low density polyethylene (LLDPE) and other plastic films are widely used in the internal and external packaging design of civil and industrial products such as fruits, food, clothing, textiles, strain planting and daily necessities. The film blowing machine is mainly composed of extruder, head, die head, cooling device, foam stabilizing frame, herringbone plate, traction roller, winding device, etc.

ABA film blowing machine uses two film blowing machines and a three-layer coextrusion die to blow plastic film. The surface layer and bottom layer share one extruder, which we call a. the other extruder extrudes the middle layer of the film, which we call B. in this way, the blown film forms a, B and a three-layer coextrusion film.

The extruder is mainly composed of screw, barrel, feeding hopper, reducer and driving motor; the reducer is driven by belt, and the reducer drives the screw to rotate in the barrel; the screw adopts special structure, that is, a special mixing device is equipped at a certain section of the screw, which is supported and centered by the surrounding plastic during operation, and the axial force of the screw shaft is determined by 7310 or 7614 installed between the reducer and the screw The feeding port of the barrel is designed according to the characteristics of raw materials, which is conducive to entering the screw groove smoothly and being sent away, so as to ensure the conveying capacity and stable extrusion quality.
