The production process and principle of ABA film blower add dry polyethylene particles into the hopper, and enter the screw from the hopper by the weight of the particles. When the particles contact with the screw oblique edge, the rotating oblique edge produces a vertical thrust against the plastics oblique edge, pushing the plastics particles forward. The main structure of the film blower is extruder, machine head, die head, cooling device and stabilization. Bubble frame, herringbone, traction roll, coiling device and other components. 1: Extruder, Extruder mainly by screw.
The barrel feeding hopper, deceleration and driving motor are made up of electromagnetic speed regulating motor (or frequency conversion common motor), which can control the fuselage and tee, and the electric heating of each button of the die through button switch respectively. The key part of the two coils is thermocouple automatic temperature measurement and automatic temperature control. In normal production process, the temperature can be automatically controlled to ensure the stability and reliability of the production process.
There are many kinds of film blowing machines, such as PE, POF and so on. This kind of particle is usually called used material. When it is made into particles, it is usually grey. When it is made into bags, pigments are usually added to make bags. The bags are unevenly colored, brittle and fragile, and the price is low.
Especially make thin bags. Main engine speed, traction speed, uncoordinated winding speed will break film. Check that the temperature automatic control is in good condition, and the heating appliances are in good condition. Pay attention to timely adjusting the heating temperature at all points within the target range.
Operators should not stand in front of the machine in order to avoid accidental injuries and operators. When feeding, it is strictly prevented that hard materials with metal impurities and operating tools that damage the machine fall into the barrel. Never wear gloves when operating a rotating machine to prevent involvement. In the range of film forming conditions, the forming temperature, cooling air temperature and blowing ratio are increased.
Then the film turbidity increases, the gloss decreases, and vice versa. It can not only break the billet, but also ensure the symmetry and stability of the membrane tube, which relatively ensures the quality of production. The function of the rotating head is to make the film look good when the thickness of the film is uniform. The lifting blower refers to the height of the coiled film can be raised or lowered. Some factories can be lowered if they are relatively short.
