PE film blower pushes plastic particles forward

PE film blower for fine printing PE film blower opportunity is more complex, for non-printing intimal bag HDPE film blower opportunity is simpler, two models should pay attention to, is the output and thickness uniformity, the first type of film blower to determine the size of the die lip based on the general thickness of the film produced, generally with a rotating die. When the grain contacts the screw bevel, the rotating bevel produces a force perpendicular to the plastics bevel.

The plastic particles are pushed forward, during which they are gradually dissolved due to friction between the plastic and the screw, between the plastic and the barrel, as well as collision and friction between the particles, as well as due to heating outside the barrel. Drive the decelerator by belt drive to rotate the screw in the barrel. The plastic melted by the hopper plastic particles heated externally is extruded from the die by three filters.

The particles are blown out with new ingredients, uniformly colored, clean and stretched. Others use recycled plastic bags to make particles, which are often called old materials and are usually grey when they are made. They usually add colors when they are made into bags, which are unevenly colored, crisp and breakable and have a lower price. Film blower produces film for all kinds of high-grade film packaging.

Because of its good barrier, freshness-keeping, moisture-proof, frost-proof, oxygen-proof and oil-resistant, this kind of membrane can be widely used in light and heavy packaging. Such as a variety of fresh fruits, meat, pickles, fresh milk, liquid drinks, medical supplies and so on. The air volume of the cooling air ring is unstable and the cooling of the film bubbles is uneven. Check the cooling air ring to ensure uniform air flow around it. The main reason for this is that there is a wear gap in the middle of the upper traction roller. The gas in the film vesicle leaks little by little from this gap. Remove the roll of the roller and grind it in the upper grinder.
