What are the precautions used plastic film blowing machine

  Plastic film blowing machine when operating the machine operator can not stand in front of Yu Zheng, in order to avoid accidentally hurt the operator. Feed film blowing machine prevent hard objects falling into the barrel of raw materials with metal impurities and the damage to the machine tools operation. The operation of rotating machinery is prohibited with gloves, in case of injury. Boot operation must first check the power wiring is disconnected, leakage; check the equipment is damaged is not normal. Before starting to ensure the safety of the various parts of the normal, so as not to affect the production and cause accidents. Die material uniform, can wear gloves slow lifting tube, and the tube billet end closed, ajar inlet regulating valve to from the center hole of the mandrel to add a small amount of compressed air, and carefully lighted foam frame, lambdoidal board, and penetrates into the traction roller, guide roll until coiling.

  Film blowing machine maintenance and maintenance work is very important, general many plastic manufacturers will be regular maintenance work of Dalian plastic film blowing machine. But the maintenance work is like a doctor to treat the same, is always ill before going to do the corresponding treatment measures. Within the scope of the film forming conditions, improve the molding temperature, cooling air temperature and blowing ratio; then the film turbidity increased, gloss decreased; otherwise improve. Boot operation must first check the power wiring is disconnected, leakage; check the equipment is damaged is not normal. Before starting to ensure the safety of the various parts of the normal, so as not to affect the production and cause accidents. Adding plastic material into the feed inlet and heating the main screw and rotary die. To be the temperature value reaches a set value, the machine startup. At this time after high-temperature melting plastic material in the main screw driven by the annular rotary die head extrusion, film extrusion after air cooled and water cooled cited wheel leads, after the embossing wheel a and embossing wheel B embossing cited into the wheel into the crimping wheel, finally by the curling wheel rolls of film is coiled into a finished product.

  For blowing high-low pressure polyethylene, the product is widely used in composite film, packaging film, agricultural covering film, textile, garment bag or film packaging; main motor using VVVF, an increase of host speed stability, and can saving 30%, the screw and barrel by 38 of chromium, molybdenum, aluminum, after nitrogen treatment, the traction frame adopts lift, no matter blow large and small size film can make the best effect of cooling. The extruder screw and barrel are made of high quality alloy steel, the hardness is high, and the corrosion resistance is good. Traction device can be electric or manual lifting, curl type, can be arbitrarily selected. For the wind of low density polyethylene (LDPE), high density polyethylene (HDPE) and linear low density polyethylene (LLDPE) plastic film, widely used in packaging of fruit, food, clothing, textile, daily necessities, such as civil and industrial activities.
