The upper rotation of the three-layer co-extrusion blown film machine refers to the 180-degree reciprocating rotation of the primary traction roller and the herringbone splint, and the film runs in radius to eliminate the "burst" phenomenon caused by the thickness of the film bubble. The film blowing die head is always stationary. The lower rotation refers to the 360-degree continuous rotation of the film blowing die head when blowing the film.
The film runs in a 360-degree cycle to eliminate the "burst" phenomenon caused by the thickness of the film bubble. The primary traction and the herringbone splint are always stationary. The three-layer co-extrusion blown film production line adopts a new high-efficiency and low-energy extruder unit, IBC film bubble internal cooling system, and ±360° horizontal upper traction rotation system.
Photoelectric automatic deviation correction device, fully automatic winding and film tension control, computer screen automatic control system and other advanced technologies. Compared with similar equipment, it has the advantages of higher output, good product plasticization, low energy consumption, and easy operation. It completely solves the problems of film ruffles and winding size heads, and takes product quality to a new level.
