When ABA film blower contacts with the screw oblique edge, the rotating oblique edge produces a vertical thrust on the plastics, pushing the plastics particles forward. In the process of pushing, the friction between the plastics and the screw, between the plastics and the barrel, as well as the collision and friction between the particles, and gradually melts due to the external heating of the barrel. The main structure of film blower is composed of extruder, die, cooling device, foam stabilizer, herringbone, traction roll and coiling device. Extruder, extruder is mainly composed of screw, barrel hopper, deceleration and drive motor, electrical control part.
General units are equipped with unit operating cabinet. The main power supply is pushed by the main button, and the main switch of the motor is turned on. The fuselage and tee can be controlled by the button switch, and the electric heating of each button of the die can be controlled separately. The key parts of the two groups of coils are thermocouple automatic temperature measurement and automatic temperature control. In normal production process, the temperature can be automatically controlled to ensure the stability and reliability of the production process. 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 melted plastic is filtered by the die to remove impurities from the die mouth and cooled by the air ring.
ABA blown film machineThe regular hoist shape of the three-layer co-extrusion film blower is due to the clamping force of the traction roll. The film blown out with the new material has a uniform color and is clean, and the finished product is well stretched. If the plastic particles made from recycled waste plastics are usually added pigments to the film, the film may be uneven coloring, brittle and fragile, and the price is low. Various fresh fruits, meat products, pickles, fresh milk, liquid drinks, medical supplies, etc. If the non-professional blower or blower does not use the correct method in the processing, then the film material may be inferior. Universal low density PE (LDPE) or linear low density PE (LLDPE) are available. HDPE film grade is generally used in areas requiring superior tensile properties and good impermeability.
