The production process and principle of PE film blowing machine add dry polyethylene particles into the hopper, and enter the screw from the hopper by the weight of the particles themselves. When the particles contact with the screw oblique edge, the rotating oblique edge produces a vertical thrust to the plastics oblique edge, pushing the plastics particles forward, in the process of pushing, blowing through the herringbone plate, pulling roll, coiling the finished film into a drum.
Frequency converter of film blower. The extruder consists of screw, barrel feeding hopper, deceleration and drive motor, air duct, blower, etc. 5: traction, which consists of traction frame, herringbone plate, traction roll, coiling mechanism and traction motor. The new material is blown out with brand new 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 particles are made, they are usually grey. ABA film blower produces films suitable for various 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.
Plastic particles are heated, melted and blown into thin films. There are many kinds of film blowing machines, such as PE, POF, PVC and so on. The new material is blown out with brand new particles. The color is uniform, clean and the bag is well stretched. The cold air is blown into the membrane bubble by the intake fan, and the hot air is discharged by the exhaust fan. The gas in and out of the membrane bubble is continuously exchanged to achieve a dynamic balance.
Rotation means adding a rotating head on the basis of a common film blower. Lifting film blower refers to the coiling height can be raised and lowered. Some factories are relatively short, which can reduce the thickness of the film. Generally, wind rings and traction speed have a great impact on the thickness of the film. You have not clearly stated what the thickness of the film is, the thickness of the single point or the whole film? The thickness of the single point should go to the screw of the film-adjusting head, and the whole thickness depends on the speed of traction.
