Polyethylene blown film curling equipment

Abstract

The invention relates to the technical field of winding machine equipment, in particular to polyethylene blown film curling equipment which comprises a rack. The two ends of the multiple traction rollers are rotationally connected with the inner wall of the rack; the first motor is used for driving one of the traction rollers fixedly connected with the first motor to rotate; the tracking roller is located behind the thin film conveyed by the traction roller, and the two ends of the tracking roller are rotationally connected with the inner wall of the rack; the second motor is used for driving the tracking roller to rotate; the rolling shaft is located behind the thin film conveyed by the tracking roller, the two ends of the rolling shaft are erected on the rack, and the two ends of the rolling shaft are two fixed shafts; the electric push rod is controlled to push the moving shaft to move in the direction opposite to the film deviation direction, the film deviation state is adjusted, and therefore it is guaranteed that the edges of the film are flush, and the quality of the polyethylene blown film curled and wound film is improved.

Description

technical field [0001] The invention relates to the technical field of winder equipment, in particular to a polyethylene blown film rolling equipment. Background technique [0002] The production of plastic film mainly includes blow molding, stretch molding, drool molding and other methods. The production process of blown film is feeding-extrusion-blowing traction-cooling-herringbone extrusion-traction roller traction- Rewinding - packaging, in which the winding part is one of the factors affecting the quality of the finished film. [0003] In the existing polyethylene film manufacturing process, after the polyethylene film is blown, the film bubble is squeezed through the herringbone splint to form the film and remove the air inside. In the process, the plastic film is affected by various interference forces, such as machine vibration, etc., which will cause the film to shift left and right and cannot keep the centerline conveying, so the film edge is uneven after the film...

AI Technical Summary

Problems solved by technology

[0003] In the existing polyethylene film manufacturing process, after the polyethylene film is blown, the film bubble is extruded by a herringbone splint to form the film and remove the air inside. After being pulled by the traction roller, it reaches the winding area until the end of the winding process. In the process, the plastic film is affected by various disturbing forces, such as machine vibration, etc.; it will cause the film to shift left and right and cannot maintain the centerline conveyance. Therefore, the edge of the film is uneven after the film is wound, which affects the quality of the film and subsequent use.
