One, Blowing Film machine is the plastic particles melt blown film and mechanical equipment. ( 1), production process and production principle of dried polyethylene particles joined under the hopper, on the particle itself weight from the hopper into the screw, when the pellet with the screw oblique edge contact, rotary oblique edge face plastic production and the oblique edge which is perpendicular to the thrust, the plastic particles moving over, passing process, as a result of plastic and plastic screw and barrel, the friction between the friction and collision among the particles, but also because the barrel externally heated and melted gradually. The molten plastic through the handpiece filter to impurities from the die head die out, the wind ring cooling, blown by the herringbone plate, the traction roller, coiling the finished film rolled into a tube. Film blowing machine with inverter

( 2), film blowing machine mainly consists of extruder, die, die, cooling device, a foam frame, lambdoidal board, a traction roller, coiling device and so on . 1: extruder, extruding machine is mainly composed of a screw, barrel hopper, deceleration and a driving motor, driving motor with electromagnetic speed regulation motor (also available frequency General Motors ), through a belt drive reducer made of screw in barrel to rotate; the hopper of plastic particles in an external heating in the case of molten plastic through the three via filtered from the die head die extrusion to 2: three, a filter net, filter plates, three the gland is composed of three parts 3: die head 4: cooling device, the cooling air ring, the wind pipe, blower, 5: traction, the traction frame, lambdoidal board, a traction roller, a winding mechanism and a traction motor and other main parts 6: electrical control part, the general units are equipped with operating cabinet, composed of total button press the total power, open the motor switch, button switch control can be respectively through the fuselage and three, die each button electric, a key part of which two groups of coil with automatic thermocouple temperature measurement and automatic temperature control, the normal production process, automatic temperature control, to ensure that the production process stability Set, reliable. There are different kinds of film blowing machine, PE, POF etc.. With new particles blown is new material, color are known, clean, good bag tensile. Some people use recycled plastic bags made of particles, the particles are generally called the old material, made of particles is usually grey, in bags are usually made of pigment, coloring made bag unevenness, brittle and easily broken, the price is lower. Although recycles the plastic bags but is generally a bag in the process of waste bag and waste plastic in the usual sense still has very big difference. Film blowing machine production is a film for a variety of high-grade packaging film. This film because of its good barrier, preservation, waterproof, anti frost, oxygen separation, oil resistance, and can be widely used for heavy package. Such as a variety of fresh fruit, meat products, pickles, fresh milk, liquid beverage, medicine and other supplies.
