The bubble tube of PE film blowing machine has problems such as gourd shape and deflection of bubble tube

Analysis and troubleshooting of gourd shaped failure of bubble tube of PE film blowing machine:

(1) The regular gourd shape of the bubble tube is due to the small clamping force of the traction roller, or the rotating speed of the traction roller is affected by the regular change of mechanical transmission resistance. Therefore, the clamping force of the traction roller shall be appropriately increased, and the mechanical transmission part of the traction device shall be repaired to make the speed of the traction roller stable.

(2) The irregular gourd shape of the bubble tube is due to unstable traction speed and too large wind pressure of the cooling air ring. In this regard, the traction speed shall be adjusted to make it run stably; The wind pressure of the air ring shall be properly reduced.

Analysis and troubleshooting of deflection of PE film blowing machine bubble tube:

(1) The temperature of the body and die is too high. It shall be reduced appropriately.

(2) The head connector temperature is too high. It shall be reduced appropriately.

(3) Uneven die discharge and uneven film thickness. Die clearance and head connector temperature shall be properly adjusted.

Analysis and troubleshooting of bubble tube swing of PE film blowing machine:

(1) The melt temperature is too high. The temperature of fuselage and nose shall be properly reduced.

(2) The cooling efficiency of the cooling air ring is too low. The cooling efficiency of the cooling system shall be improved, and the air pressure and air volume of the air ring can be appropriately increased.

(3) The friction between the bubble tube and the herringbone splint is too large. The included angle of the herringbone plate shall be appropriately increased to reduce the contact area between the bubble tube and the splint.

(4) The head temperature is too low, it is difficult to discharge, and the film bubble jumps. Properly increase the head temperature and screw speed.

Analysis and troubleshooting of film surface blooming of PE film blowing machine:

(1) The temperature of the fuselage or nose is low and the melt plasticization is poor. The temperature of the fuselage or nose shall be properly increased

(2) The screw speed is too fast. Slow down properly.

(3) Screw temperature is too high or too low. The screw temperature shall be controlled within the appropriate temperature range by adjusting the flow of cooling medium in the screw.
