PVC food fresh-keeping film blowing machine

This paper introduces the advantages of PVC fresh-keeping Film Blowing Machine.

1. The machine is firm, the use of H steel + track reinforced is firm and stable, the production process will not shake

2. The motor of extruder is Shanghai Dedong variable frequency motor with stable performance;

3. The reducer is equipped with plate cooling oil pump to keep the thrust shaft bearing lubricated and increase the service life. The barrel screw is designed according to the performance of PVC material (good plasticizing effect, no raw material, high extrusion volume); Ceramic heater (fast heating and heat dissipation) and fan made in Taiwan have good cooling effect;

4. The hopper is made of stainless steel and equipped with automatic feeder.

5. Sj75 main engine electric control box 7 groups of temperature control instrument independent display (5 groups of barrel and 2 groups of mold temperature), and equipped with independent display motor tachometer (R / min) and current (a); Each group had its own display;

6. The mould is designed and produced by ourselves, processed by imported CNC lathe, made of 42gm gold material, heat treated and vacuum quenched, with high precision of roundness, coaxiality and perpendicularity. After three injection standard test, it is equipped with 360 ºC rotating mould center feeding (250) and high-pressure rotating integral rotating air ring, with 6 air inlets rotating and distributing to make the material plasticize evenly and ensure uniform thickness (good film transparency), The high-pressure centrifugal fan is used for frequency control, the air volume is balanced, and the disassembly is equipped with a special die wrench;

7. The traction system consists of three layers of auxiliary machine, one layer of main machine, 160 * 160 square tube of traction frame body, two layers of foam stabilizing device, three layers of herringbone splint, and a bridge between auxiliary machine and winder;

8. A group of traction (3 layers) stainless steel herringbone splint traction roller 1600mm. Three phase asynchronous motor turbine reducer

9. Two groups of traction: fully automatic friction winding, with 2 transverse knives, 4 longitudinal knives, double-layer film winding, longitudinal online cutting single piece;

10. Three groups of traction double position automatic film cutting, automatic coil changing and automatic unloading, with a linear speed of 60m / min;

11. Equipped with surplus edge winder;

12. Size: 10M long, 3M wide, 7.5m high, installed capacity: 72kw. Normal power consumption: 50KW. Output: 110kg per hour;

11. The three groups of traction rollers have independent speed regulation, display, and synchronous speed regulation at the same time. The electrical appliances are of well-known brands (with three guarantees service),

This machine has the advantages of simple operation, stable performance, less waste, high qualified rate, reasonable design, beautiful appearance, high quality material selection and collocation to increase the texture and service life of the machine.
