The correct use of the three layer co-extrusion blown film machine
- Aug 28, 2018 -

The appearance and application of the three layer co-extrusion blown film machine has significantly improved the quality of the finished product, and easily solved the problems of the conventional film ruffle and the size of the winding head. Moreover, the three-layer co-extrusion blown film machine has the advantages of higher output, good plasticization of products, low energy consumption, and easy operation. So what problems should you pay attention to in daily use?


First of all, we need to check and confirm that the temperature automatic control system and heating appliance of the three layer co-extrusion blown film machines are in good condition. Note that the heating temperature of each point is adjusted within the range of the indicator. The second is to check the traction speed and control the film thickness. Then observe whether the thickness of the adjustment film is uniform, and the folding diameter should conform to the standard. Next check the air storage cylinder pressure, not too high, but there should be spare pressure.


In addition, before using the three layer co-extrusion blown film machine, the staff should also confirm that the raw material ratio is appropriate and evenly mixed. At the same time, it is necessary to check whether the raw materials have impurities or not. In particular, the iron should be inspected in time with a magnet. Regularly check the lubrication of the gearbox and the cylinder of the air compressor. Always check the temperature rise and mechanical transmission of each running motor.
