Dalian blown film correct use of the unit

Polypropylene unit blown film extrusion machine, machine barrel and screw adopt high quality alloy steel, after nitriding processing and precision machining, which has the best of the hardness and corrosion resistance, the special designed screw high output, good plasticification. Main motor adopts frequency control of motor speed, increase the stability of the host speed, screw cylinder aluminum 38 chrome molybdenum, after nitriding process, drawing frame adopts lift, no matter big and small size film can make the best cooling effect. Torque winding winding adopts independent center, with rotary die head blown film is better. General units are fitted with units operation counters, by the button according to the total power supply, open the main switch, motor, respectively through the toggle switch and control the fuselage and tee, mouth mold each knob electric heating, a key part of two sets of coil adopted thermocouple temperature measurement and automatic temperature control automatically, the normal production process, the temperature can be automatically controlled, to ensure stable and reliable production process. Film blowing machine and a lot of kinds, there is PE, POF, and so on. Blow out the new particle is a new material, colour and lustre are, according to clean, good tensile bag. Also somebody made from recycled plastic bags to the particle, the particle generally called the old material, made of particles is usually gray, usually to add pigment, when it made the bag made from bags to uneven color, brittle and break easily, the price is low.

Blown film machine, the correct way of using the first check the temperature control in good condition, heating appliances in good condition, pay attention to timely adjust the heating temperature of each point in the range of indicators. Then check that the drawing speed, control the film thickness. Adjust the film thickness evenly in observation, folding size up to the standard. Check air storage cylinder pressure in turn, can not be too high, but shall have the standby pressure. Check control raw material and mixing ratio. Check whether there is any impurities on raw materials, particularly immediately with the iron mixed with magnetic inspection. Check the reduction space and air compressor cylinder lubricating oil. Regularly check the running motor temperature rise and mechanical transmission.
