At present, the film blowing machine is mainly applicable to the packaging of food, medicinal materials, industrial products and export plastic packaging, fruit, food and so on. Since the film blowing machine is so popular, do you need to know its structure during production?
It is mainly composed of extruder, head, die, cooling device, bubble stabilizer, herringbone plate, traction roller and coiling device
1: Extruder: the extruder is mainly composed of screw, barrel and hopper, speed reduction and drive motor. The drive motor is an electromagnetic speed regulating motor (or a frequency conversion ordinary motor), which drives the reducer through belt drive to make the screw rotate in the barrel; When the plastic particles in the hopper are heated externally, the molten plastic is extruded from the die mouth of the die through three-way filtration
2: Tee, consisting of filter screen, filter plate and tee gland
3: Die
4: Cooling device, composed of cooling air ring, air duct, blower, etc
5: Traction, consisting of traction frame, herringbone plate, traction roller, coiling mechanism, traction motor and other main components
6: In the electrical control part, the general unit is equipped with the unit operation cabinet. The main button is used to turn on the main power supply and turn on the main switch of the motor. The main body and tee can be controlled by the sub button switch, and the electric heating of each button of the die. The two groups of coils in the key part are automatically measured and controlled by thermocouples. In the normal production process, the temperature can be automatically controlled to ensure the stability and reliability of the production process.
