Blown film machine main performance and characteristics

Guanhua Plastic made film blowing machine technical feature

Film blowing machine mainly consists of extruder, head, die head, cooling device, foam stabiliser, herringbone plate, haul-off rollers, winding device and so on.1.Extruder:One screw adopts advanced alloy spraying technology, higher hardness. Better corrosion resistance. Longer service life. 2~3 times longer than nitriding screws Peculiar screw L/D ratio is large. Strong plasticising ability. Uniform temperature distribution. Automatic temperature control. Blown film is bright and even. Good product performance.

The extruder is mainly composed of screw, barrel, feed hopper, reducer and driving motor. The reducer is driven through the belt. The reducer drives the screw to rotate in the barrel; the screw adopts a special structure. That is, in a section of the screw is equipped with a special mixing device. When working, it relies on the surrounding plastic to support and centre. The axial force of the screw shaft is borne by the 7310 or 7614 bearing installed between the reducer and the screw. The barrel inlet is designed according to the characteristics of the raw material. It facilitates smooth entry into the screw chute and feeding out. Ensure conveying capacity and stable extrusion quality.

2.Die-head:The head consists of three parts: screen, filter plate and head gland. In order to adapt to the production of plastic raw materials containing more impurities, this unit adopts the right-angle head structure with larger filter area. Considering the high pressure, low pressure, mixture and recycling materials with large mechanical viscosity. Reasonable choice of material flow channel design. Extrude the filter plate by using the drive motor of the extruder. It can be adapted to single screen change operation.

3. Compact structure of the whole machine. Stable operation. Single arm structure. Economical and practical. One piece of traction device,Self-adjustable.

4. Adopt advanced frequency conversion technology. Energy saving.

5.Be careful with the air pot in various forms. Can be chosen arbitrarily.

6. The rotary head can be configured according to user requirements.

7.Suitable for blow moulding polyethylene, high density polyethylene and linear polyethylene (LLDPE). Widely used for internal and external packaging of civil and industrial products such as fruits, foodstuffs, garments, textiles, strain cultivation and daily necessities.
