he transformation of mechanical manufacturing technology will promote the development of film blowing machine, plastic industry for a long time, the plastics industry is dependent on foreign advanced machinery and equipment, the introduction of foreign technology, will improve the plastic industry and plastic industry production cost, mode of development not only improves the performance of intelligent plastic film blowing machine, can reduce cost, reduce working time will be significantly to improve the plastic industry status quo.
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.
During the pushing process, the friction between plastic and screw and plastic and barrel, as well as the collision and friction between particles, is also due to the melting of plastics due to the external heating of the barrel. The operating technician, as a film blowing machine, checks the temperature of the machine about every 30 minutes to see if it is the standard temperature value at work. If the temperature of the heater is overheated or too low, please adjust the temperature in time so that it will be beneficial to the normal operation of the machine and the quality of the products.
As is known to all, there is a certain gap between domestic mechanization development and developed countries. But with the development of science and technology in China, this gap is also shrinking. At the same time, we can not find that even so, many companies still spend a lot of money to buy foreign machines and equipment.
In order to facilitate the film blowing and normal blowing, the temperature of the blowing machine needs a best temperature, and how the temperature will be controlled. According to the melting theory of plastic, the extruder screw of the blown film is divided into three segments: feeding section, melting section and homogenization section. At the end of the feeding section, when the melting section begins, according to the melting theory, its temperature should be the temperature of the viscous flow.
