Main structure of film blowing machine
Release time：2024-06-06
It is mainly composed of extruder, head, die head, cooling device, foam stabilization rack, herringbone plate, traction roller, coiling device, etc.
Main structure
It is mainly composed of extruder, head, die head, cooling device, foam stabilization rack, herringbone plate, traction roller, winding device, etc.
Extruder
The extruder is mainly composed of screw, barrel, hopper, deceleration and drive motor. The drive motor adopts electromagnetic speed regulating motor (frequency conversion ordinary motor can also be used), and the reducer is driven by belt transmission to make the screw rotate in the barrel. The molten plastic of the hopper plastic particles is extruded from the die mouth through three-way filtration under the condition of external heating.
Die head
The unit selects advanced spiral die head structure, according to the particularity of high pressure, low pressure, mixture, recycled polyethylene materials, comprehensive consideration, the design of the spiral angle, back slope angle, shaping angle length, die opening and other main technical parameters, through many comparative tests to select the best shaping,
Cooling device
Composed of cooling air ring, air duct, blower, etc.
Elastics
It is composed of traction frame, herringbone plate, traction roller, winding mechanism and traction motor.
Electrical control
Generally, the unit is equipped with a unit operation cabinet. The main power supply is turned on by the main button, and the main switch of the motor is turned on. The main body and the three-way joint can be controlled by the sub-button switch respectively. The buttons of the mouth die are electrically heated. The two sets of coils of the key parts use thermocouples to automatically measure temperature andautomatic temperature controlIn the normal production process, the temperature can be automatically controlled to ensure that the production process is stable and reliable. There are many kinds of film blowing machine, PE,POF and so on.
Blowing out with brand new particles is a new material, the color is all said, clean, the bag stretches well.
Some people also use recycled plastic bags to make particles, which are generally called old materials. When made into particles, they are usually gray. When made into bags, pigments are usually added to make bags with uneven coloring, crisp and easy to break, and the price is lower.
Use
Although it is a recycled plastic bag, there is a big difference between the waste bag in the bag making process and the garbage plastic in the usual sense.
Blown film machine production is suitable for all kinds of high-grade film packaging. This film can be widely used in light and heavy packaging due to its good barrier properties, preservation, moisture resistance, frost resistance, oxygen barrier and oil resistance. Such as all kinds of fresh fruit, meat food, pickles, fresh milk, liquid drinks, medical supplies, etc.
