Film blowing machine production process is firstly added polyethylene particles drying hopper, then particles by their own weight from the hopper into the screw thread, when the screw and the oblique edge contact, the rotation of the face of the plastic face aslant vertical thrust and aslant, the particle goes forward.
In the push process, the friction between the plastic and the screw and the plastic and the cylinder, as well as the collision and friction between the particles, is also melted by the external heating of the cylinder. Three layer co extrusion film blowing machine using the new production line with high efficiency and low energy consumption extrusion unit, IBC internal bubble cooling system, rotation traction system + 360 degrees horizontal, photoelectric automatic correction device, automatic tension control and roll film, advanced technology and automatic control system of computer screen.
In order to meet the needs of plastic film packaging material some special features of the production process, the various properties of the material (e.g., breathable, waterproof, thermal insulation and toughness) and co extrusion film together, plastic film formation function, development of multi-layer co extrusion film blowing machine.
In industry, it is often applied to many machines, and there are many kinds of machines. In plastic bags, packaging and other production will often be applied to a machine, that is, three layer co extrusion film blowing machine. Before using the machine, it is necessary to check the power supply of the machine, whether there is a break, leakage, etc., if there is such a phenomenon. Leakage and other phenomena will pose a great threat to the safety of construction personnel, so be sure to carefully check. Film blowing machine in the processing process to get quality control of plastic bag products, it is necessary to control the processing link in place.
Under normal circumstances, the processing process of plastic film blowing machine is divided into feeding heating, traction and control of the compressor edge. After the film head blows the air, the gas is added to the middle of the round film, the film is made up in a straight line, the size of the plastic bag is controlled by the blowing amount, and then the film stabilizing device is used to stabilize the membrane.
