Film blowing machine

Film blowing machine set cylinder and screw adopt high quality steel, tight nitriding treatment and precision machining, with the best hardness and corrosion resistance, special design of screw has the advantages of high yield, good plasticization. Suitable for blowing low density polyethylene high density polyethylene linear low density polyethylene and other plastic film, widely used in food, clothing, garbage bags, vest bags and other civilian and industrial packaging. Die material uniform, can wear gloves slow lifting tube, and the tube billet end closed, ajar inlet regulating valve, from the center hole of the mandrel blown into a small amount of compressed air, and then carefully lighted foam frame, lambdoidal board, and penetrates into the traction roller, guide roll until coiling. Film blowing machine installation should pay attention to adjusting extrusion machine head center line and traction roll center to maintain horizontal and vertical, and shall not deviate from the skew. When receiving the volume, the increase of the diameter of the receiving coil, please pay attention to the coordination of the traction speed and the rolling speed. After the host is open, pay close attention to the operation of the host, timely adjustment, correction, electrical instruments, controllers to ensure its normal operation. Main gear box, traction reducer should be refueled frequently, the replacement of gear oil, the new machine please in the use of 10 days or so to replace the new gear oil, to ensure that the rotating parts of the normal operation, filling the attention, prevent jammed and overheat damage, should also check the connecting parts of the fastening situation, to prevent loosening of the bolt Luo. The compressed air in the bubble tube should be kept in proper amount, because the compressed air leakage will be brought out in the process of traction.
