General units of PE film blower are equipped with unit operating cabinet. The main power supply is pushed by the main button, and the main switch of the motor is turned on. The fuselage and tee can be controlled separately by the button switch, and the electric heating of each button of the die can be controlled. The key parts of the two groups of coils are thermocouple automatic temperature measurement and automatic temperature control. In normal production process, the temperature can be controlled automatically. Ensure that the production process is stable and reliable. There are many kinds of blown film machines, such as PE, POF and so on.
Measure the size of the barrel, including the length of the circumference. Calculate the required insulation cotton and estimate the position of the winding according to the power of the original heating ring. The insulation cotton is wrapped on the barrel and tightened with high temperature bandage, so that the thickness of the insulation cotton is kept at 1.5-2.0CM. In order to make the installation more beautiful, a layer of 0.5mm insulation resin board can be wrapped on the insulation cotton. Winding the electromagnetic wire on the wrapped cartridge should be as tight as possible.
Install electromagnetic heating control cabinet. Before starting and stopping the machine, use pure copper scraper to clean the accumulated material, paraffin to clean the film mouth, and reduce the influence of precipitates on the membrane bubbles. Protect the felt in time after shutting down to avoid mold damage. Regularly check the temperature zone and the temperature and current of the heating plug, and correct the temperature difference. Correction of die level and center point matching with traction. Mould screw is disassembled using torque wrench and operated according to specified torque. Molybdenum disulfide grease is used for high temperature part of screw. It is forbidden to weld and cut moulds.
