How to Inspect Three-layer Co-extrusion Film Blower

Release date:2018-11-30 10:30 Source: Click:

  The three-layer co-extrusion film blower checks whether the normal voltage and the pump and valve are normal and effective, and checks whether the circuit of each part is correct, checks whether the oil level of the three reducers meets the standard, and timely overhauls and treatments if abnormal conditions occur. After all is normal, the heating begins. First, the die head 1.2 is heated in zone 3 and zone 4, 5 and 6 for about two hours, then the temperature in zone 1, 2 and 3 is heated.


  In accordance with the production instructions, adjust the plug-in board and the herringbone to the standard position, and adjust in time if any abnormalities occur after boot-up. Observe whether the cots are opened (to facilitate the smooth introduction of the membrane bubble into the cots) check whether there are pastes and debris around the die mouth, and clean up. 7. When the temperature reaches the standard, the machine can start.


  Start the main motor, run at low speed, extrude the molten material. After extruding the material, connect the air pump to inflate, and form the film bubbles. Then turn on the fan immediately. The air volume is adjusted according to the frost line of the film bubbles properly. If the air volume is too large, it will float on the film bubbles, and if the air volume is too small, the film cooling is not good and the stiffness is not good. The membrane vesicle tube is fed into the traction roll and coiled along the guide roll.
