The PE film blowing machine heats and melts polyethylene plastic particles and blows them into films.
It is mainly composed of extruder, machine head, die head, cooling device, bubble stabilizer, herringbone plate, traction roller, coiling device, etc.
The extruder is mainly composed of a screw, a barrel, a hopper, a speed reducer and a drive motor. The drive motor adopts a frequency conversion motor, and the reducer is driven by a belt to make the screw rotate in the barrel; the plastic particles in the hopper are heated externally . The molten plastic is extruded from the die opening through three-pass filtering.
The unit has two options of fixed die head and rotary die head structure.
Composed of cooling air ring, air duct, blower, etc.
It consists of main components such as traction frame, herringbone plate, traction roller, coiling mechanism and traction motor .
Generally, the unit is equipped with a unit operation cabinet. Press the main button to turn on the main power supply, turn on the main switch of the motor, and control the fuselage and the three-way through the sub-button switch. Each button of the die is electrically heated, and the two sets of coils in the key part are made of thermocouples. Automatic temperature measurement and automatic temperature control . During normal production process, the temperature can be automatically controlled to ensure stable and reliable production process. The material blown out with brand new particles has uniform color and luster, clean, and the bag stretches well.
Some people also use recycled plastic bags to make granules. This kind of granules are generally called old materials. When they are made into granules, they are usually gray. When they are made into bags, pigments are usually added. The resulting bags are unevenly colored, brittle and easy to break. , the price is also lower.
The film produced by the film blowing machine is suitable for various high-grade film packaging. This film can be widely used in light and heavy packaging due to its good barrier properties, freshness preservation, moisture resistance, frost resistance, oxygen barrier and oil resistance. Such as various fresh fruits, meat products, pickles, fresh milk, liquid beverages, medical supplies, etc.
