Ziplock blown film machine adopts unique structure

The production process and production principle of the zipper bag blown film machine: The dry polyethylene particles are added into the lower hopper, and the weight of the particles enters the screw from the hopper. After the pellets come into contact with the inclined bevel, the rotating oblique ribs face the plastic. Produces a thrust that is perpendicular to the beveled face, pushing the plastic particles forward.

During the transition, due to the friction between the plastic and the screw, the plastic and the barrel, and the friction between the particles, it is gradually dissolved due to the external heating of the barrel. The melted plastic is filtered through the machine head to remove impurities from the die orifice, cooled by the air ring, blown through the herringbone, and pulled and rolled to wind the finished film into a drum. Uses and characteristics The equipment adopts double frequency conversion speed regulation, which can save electricity for you. The extruder, barrel and screw of this unit are all made of high quality alloy steel, tightly nitrided and precision machined, with the best hardness and corrosion resistance. , Specially designed screw output is high, plasticization is good. Suitable for blowing low density polyethylene (HDPE) linear low density polyethylene (LLDPE) and other plastic films, widely used in food and clothing, garbage bags, vest bags and other civilian and industrial packaging.

Low-pressure polyethylene (HDPE) and linear low-density polyethylene (JJDPE) are new varieties of polyethylene that have been mass-produced on the international market in recent years. Because it has excellent impact strength, puncture resistance, resistance to environmental stress cracking, low temperature resistance, in particular, can be made of micro-film (1.5 thread thick film strength can be reached on the 3 wire thickness of high-pressure polyethylene film) . The use of low cost, so a large number of blown film. It can blow low pressure, high pressure, linear low density three kinds of polyethylene film, not only adapt to their new material blown film, but also suitable for their regenerated plastic blown film, stable performance, reliable quality, this film blowing machine adopts special structure spiral Rod Extruder, Advanced Spiral Die Head, Adjustable Flexible Cooling Air Ring, Reasonable Aperture Stabilized Bubble Structure, Guaranteed Uniformity of Three Kinds of Polyethylene and Different Ratios of Mixed Plastics.
