Advantages of internal cooling control system for three-layer co extrusion film blowing machine

1) With the rapid development of plastic industry and the emergence of various new raw materials, people have increasingly strict requirements for plastic products. Traditional fans and wind rings have been difficult to meet the requirements, which will lead to instability of membrane bubbles and low output. The appearance of membrane bubble internal cooling system solves the problem of traditional wind ring. One of the advantages of large Z is high product output.

2) Smooth operation of the film bubble ensures good transparency of the film

3) The opening of the film is good

4) The tensile strength and tear strength of the film have also been greatly improved.

The energy saving of the three-layer co extrusion film blowing machine can be divided into two parts: one is the power part, and the other is the heating part.

Power part energy saving: most of them use frequency converters. The way to save energy is by saving the residual energy consumption of the motor. For example, the actual power of the motor is 50 Hz, but you only need 30 Hz in production. The excess energy consumption is wasted. The frequency converter is to change the power output of the motor to save energy.

Energy saving of heating part: Most of the energy saving of heating part is realized by electromagnetic heater, and the energy saving rate is about 30% - 70% of the old resistance coil.

1. Compared with resistance heating, the electromagnetic heater has an additional insulation layer, which increases the utilization rate of heat energy.

2. Compared with resistance heating, the electromagnetic heater directly acts on the material pipe heating, reducing the heat loss of heat transfer.

3. Compared with resistance heating, the heating speed of electromagnetic heater is more than a quarter faster, reducing the heating time.

4. Compared with resistance heating, the electromagnetic heater has a faster heating speed, which improves the production efficiency and makes the motor saturated, reducing the power loss caused by high power and low demand.The above four points are the reasons why we can save energy as much as 30% - 70% on film blowers.
