What issues to pay attention to when using a three-layer co extrusion blown film machine

The three-layer co extrusion blown film machine adopts advanced technologies such as a new high-efficiency and low energy consumption 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.

At the beginning of the melting section, the temperature of the three-layer co extrusion blown film machine needs to reach the viscous flow temperature in order to melt. For crystalline resins, the viscous flow temperature is equal to the melting point temperature. Then the melt layer continues to compress and rise, requiring a continuous increase in temperature to change the molecular chain length of the resin. Polymers with different thermal kinetic energies are melted one by one. Therefore, after determining the temperature at the end of the melting section of the three-layer co extrusion blown film machine, it can be determined that the other parts in the middle and upper parts of the section are linearly heating up.

What issues to pay attention to when using a three-layer co extrusion blown film machine

During the heating process of the equipment for 3 to 4 hours, each heating part should be checked for normal operation and the pointer of the voltage and current meter should be checked. If there are any problems, they should be repaired in a timely manner.

2. After starting, the host should be turned on at a speed of 15-20 revolutions per minute. Observe the plasticization of the materials, the pressure and current of the host, and strictly prohibit forced starting before heating (if heating is not reached, it will cause mold misalignment and uneven film thickness).

During the production process, operators are not allowed to stay away from the winding area to prevent unexpected situations from being detected and dealt with in a timely manner. When winding, attention should be paid to the position of the knife and hands to ensure safety first.

4. When cleaning the film mouth and changing the mesh, protective gloves should be worn, and attention should be paid to the exposed parts of the wiring terminals at the machine head to avoid electric shock injuries; When cleaning the film port and changing the screen, a copper shovel must be used to avoid damaging the film port and changing the screen. At the same time, the machine should be stopped for replacement.

The three-layer co extrusion blown film machine is a device that heats and melts plastic particles, and blows them into thin films. There are many types of three-layer co extrusion blown film machines, including PE, POF, etc. The films produced by blow molding machines are widely used in multiple fields based on different materials and characteristics. Suitable for various film packaging, plastic bag film, protective film, etc. This type of film has good barrier properties, freshness, moisture resistance, frost resistance, and antioxidant properties, and can be widely used for barrier properties and oil resistance in light and heavy packaging. Such as various fresh fruits, meat products, Pickled vegetables, fresh milk, liquid drinks, medical supplies, etc.

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;
