The production principle of three-layer co extrusion blown film machine

Plastic packaging is a large packaging industry in the market, and products made by blow molding machines provide convenience for people's lives. So, in order to meet people's needs and meet environmental standards, what is the relationship between the two? Packaging is an indispensable part of the current popular packaging market, mainly for plastics, paper, and film blow molding machines. The blow molding industry has a large market share, but with the increasingly strict requirements for environmental protection and energy conservation in the paper industry, the cost of expanding paper packaging in the market has increased.

This has led to a corresponding increase in the market share of plastic packaging, promoting the development of the blow molding machine manufacturing machinery industry, and the emphasis on environmental protection and energy-saving technology in the blow molding machine machinery industry, in order to promote the high end level of blow molding machines. The frequency converter adopts Delta M series frequency converters. The Delta M series frequency converter has functions such as automatic torque compensation, slip compensation, and automatic voltage stabilization. In the case of frequent starting and stopping of the motor, it can effectively protect the motor, avoid the impact of starting current on the power grid, and effectively achieve energy conservation and consumption reduction.

The temperature controller adopts Delta DTA4848R. The Delta air conditioner has a self-tuning function, and the temperature error is controlled within 0.1 degrees. The production principle of the three-layer co extrusion blown film machine is to use advanced technologies such as a new high-efficiency and low-energy extrusion unit, IBC film bubble internal cooling system, ± 360 ° horizontal upward traction rotation system, photoelectric automatic correction device, fully automatic winding and film tension control, and computer screen automatic control system. Compared with similar equipment, it has the advantages of higher output, better product plasticization, low energy consumption, and simple operation, completely solving problems such as film ruffles and winding heads, and taking product quality to a new level.

The produced film has high transparency, puncture resistance, high toughness, good low-temperature heat cutting performance, good composite fastness, and anti curling properties. Do not wear gloves when operating a rotating machine to prevent getting caught and injured. Check and add lubricating oil in the gearbox and air compressor, and check the lubrication of various mechanical transmission components. Avoid damaging the machine and making noise during dry operation. Before starting up, it is necessary to check whether the wiring of each power supply is disconnected or has leakage; Check if the instrument is damaged or abnormal. Dalian Blowing Film Unit

Dry polyethylene particles are added to the feeding hopper and enter the screw through the weight of the particles themselves. When the particles come into contact with the threaded edge, the rotating edge generates a thrust perpendicular to the plastic surface, pushing the plastic particles forward. During the pushing process, due to the friction between the plastic material and the screw, the plastic and the machine barrel, as well as the collision and friction between the particles, the particles gradually dissolve due to external heating of the barrel. The molten plastic is filtered by the machine head to remove impurities and comes out of the mold mouth. It is cooled by an air ring, blown and expanded through a herringbone board, pulled by a roller, and rolled into a cylinder to roll the finished film.
