The three layer co extrusion thin blowing production line adopts new high efficiency and low energy consumption extruding unit, IBC film bubble cooling system, 360 + horizontal horizontal traction rotary system, photoelectric automatic correction device, automatic roll up and film tension control, computer screen automatic control system and other advanced technology.
Compared with the similar equipment, it has the advantages of higher yield, better plasticization, low energy consumption and simple operation. It solves the problems of thin film lotus leaf and volume size, and makes the product quality go up to a new level. The rapid development of plastic film blowing machine industry has two main factors: the rapid upgrading of equipment and the obsolescence of old equipment, and the rapid development of plastic processing industry, and the demand for plastic film blowing machine. We should make full use of the opportunities brought by China's entry into the WTO and expand the development of China's mechanical industry.
With the internationalization of the domestic market, international oil prices continue to rise, the market is at a high level of plastic raw materials, coupled with the domestic labor wages rise, electricity price increases, which makes the film production costs increase, the domestic film manufacturers in an increase production and profit decline in operating conditions. The three layer coextrusion blowing machine is an important industry in the plastic industry.
At present, most of the domestic manufacturers of thin film blowing machines are not suited to the market demand and the technology that needs to be improved to produce the membrane blower in the market. In order to get the plastic bag product with controllable quality in the process of processing, the processing links should be controlled in place.
In general, the processing process of the film blowing machine is divided into heating, pulling and controlling the edge of the air pressure. After adding gas to the membrane head and adding gas to the middle of the circular membrane, the film is straight up. The size of the plastic bag is controlled by how much air is blown, then the film is stabilized by the film stabilizing device.
