PE Film Blower Moves Plastic Particles Forward

Release date:2019-06-28 10:09 Source: Click:

  PE film blower for fine printing has more complicated opportunities. HDPE film blower for non-printing inner film bag has simpler opportunities. Both models should pay attention to the output and thickness uniformity. The first type of film blower is to determine the size of die lip according to the thickness of the film produced, and it is usually equipped with rotating die. When the grain is in contact with the screw bevel, the rotating bevel produces thrust perpendicular to the plastics bevel.


  The plastic particles are pushed forward. During the pushing process, the friction between the plastic and the screw, the friction between the plastic and the barrel, the collision and friction between the particles, and the gradual melting due to the external heating of the barrel. The screw rotates in the barrel by belt drive, and the melted plastic particles in the hopper are extruded from the die through three filters under the condition of external heating.


  The new material is blown out by the particles, the color is uniform, clean and the bag is well stretched. Others use recycled plastic bags to make particles, which are generally called used materials. When they are made into particles, they are usually grey. When they are made into bags, they usually need to add pigments. The bags are uneven in color, brittle and fragile, and the price is low. Blowing film machine produces film which is suitable for all kinds of high-grade film packaging.


  Because of its good barrier, fresh-keeping, moisture-proof, frost-proof, oxygen-proof and oil-proof, the film can be widely used in light and heavy packaging. Such as all kinds of fresh fruits, meat products, pickles, fresh milk, liquid drinks, medical supplies and so on. The air volume of the cooling air ring is unstable and the film bubble is not uniform; check the cooling air ring to ensure that the air supply around is uniform and consistent; the main reason is that there is a wear gap in the upper traction pinch roll, and the gas in the film bubble leaks out bit by bit from this gap. Remove the rubber roll of the pinch roll and grind it on the grinder. Okay!
