Rotation on a three-layer co-extrusion film blower refers to a 180 degree round-trip rotation of the traction roll and the herringbone splint, and the radius operation of the film eliminates the phenomenon of "rebound tendons" caused by the thickness of the membrane vesicles. The film blowing head is always stationary. Down-rotation refers to the continuous 360-degree rotation of the film blowing head during film blowing.

The membrane is circulated 360 degrees to eliminate the phenomenon of "rebound tendons" caused by the thickness of the membrane vesicles. One traction and the herringbone are always stationary. The three-layer co-extrusion thin-blown production line uses a new type of high efficiency and low energy consumption extrusion unit, IBC foam internal cooling system, +360 degree horizontal upward traction rotation system.

Advanced technologies such as photoelectric automatic deviation correction device, automatic winding and film tension control, computer screen automatic control system, etc. Compared with similar equipment, it has the advantages of higher output, better plasticization of products, low energy consumption and easy operation. It thoroughly solves the problems of lotus leaf edge of film and the size of roll-up head, and improves the product quality to a new level.
