The plastic particles are heated to melt and then blown into a film blowing unit.

The dalian blowing film unit is a plastic particle heated to melt and blown into a film. There are many kinds of blowing machine, PE,POF,PVC and so on. The new particles blow out the new material, the color is said to be clean, the bag is stretched. The energy saving of the film blowing machine can be divided into two parts: one is the power part and the other is the heating part.

Energy-saving power parts: mostly adopts frequency converter, motor energy saving way is by saving more energy, the real power of the motor is 50 hz, for example, and in production, in fact, you only need 30 hz enough production, that extra energy is wasted, the inverter is to change the motor power output to achieve the effect of energy saving. Heating part energy saving: most of the energy saving of heating is energy-saving with electromagnetic heater, and the energy saving rate is about 30% to 70% of the old resistance circle.

Will dry polyethylene particles added to the hopper, depend on the weight of the particles themselves from the hopper into the screw, when the aggregate after contact with thread oblique edge rotating slant edge face plastic produce and inclined faces the vertical edges of thrust, plastic particles move, goes on in the process, because the plastic and screw, plastic and barrel friction between the friction and collision between particles, but also gradually melt due to external heating cylinder. The molten plastic is filtered through the head to remove impurities from the die head, through the wind ring cooling, blowing through the human word board, drawing roll, and winding the finished film into a tube.

Complete inspection of equipment. Check whether the connections are correct and firm; Check whether the movement of each drive and moving parts is flexible, whether it is safe and reliable, whether the movement is correct or not, and the fault is eliminated in time. Carefully check the clearance of the die with a feeler to make the circumference uniform, and the clearance value should meet the technical requirements.

Check whether the electrical system is grounded, safe and reliable, and whether the water supply system and compressed air system are smooth and free of leakage. Check whether the fan is normal, and the cooling water of the screw and barrel is clear.

The film is produced by the film blowing machine, which is widely used in various fields according to the different materials and characteristics. Suitable for all kinds of high-grade film packaging, plastic bag film, protective film and so on. The film is widely used for heavy and heavy packaging because of its good barrier properties, fresh, moisture-proof, frost-proof, oxygen resistant and oil resistant. If all kinds of fresh fruit, meat food, pickles, fresh milk, liquid beverage, medical supplies, etc.
