Main Structure Of Film Blowing Machine

- Sep 27, 2017 -

Extruder

Extruder is mainly composed of screw, barrel and hopper, deceleration and drive motor, the drive motor adopts the electromagnetic speed-regulating motor (also can be used as frequency conversion ordinary motor), through the belt drive drive the reducer to make the screw in the barrel rotation movement; so that the plastic pellets of the hopper are heated externally, the molten plastic is filtered through a tee and squeezed from the die mouth.

Die Head

This unit selects the Advanced Helix mold head structure, according to the high pressure, the low pressure, the mixture, the recycled raw materials polyethylene material particularity, comprehensively considers, has designed the helix angle, the this angle, the shape angle length, the mold opening degree and so on the main technical parameter, after several times contrast experiment carries on the optimized

Cooling device

Composed of cooling air ring, duct, blower, etc.

Traction

The main components of traction frame, herringbone board, Traction Roller, take-up mechanism and traction motor are made

Electrical control

General units are equipped with a unit operating cabinet, by the total button according to the total power supply, open the total motor switch, respectively, through the button switch control fuselage and tee, the mouth mold each button electrothermal, the key part of the two groups of coils using automatic thermocouple temperature measurement and automatic temperature control, normal production process, the temperature can be automatically controlled to ensure that the production process is stable and reliable. Film Blowing machine is divided into many kinds, there is PE, POF and so on.

New particles are blown out with fresh material, the color is said to be clean, the bag is stretched well.

Some people also use recycled plastic bags to make particles, which are generally called old materials, made of particles are usually gray, in the making of bags usually add pigment, made of bag coloring unevenness, brittle and easy to break, the price is lower.
