Rotation on the 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 "bulging ribs" caused by the thickness of the film bubbles. The film blowing die is always in a static state. The downward rotation refers to the continuous 360 degree rotation of the film blowing die head during the film blowing process.
The membrane circulates 360 degrees to eliminate the phenomenon of "bulging tendons" caused by the thickness of the membrane vesicles. The primary traction and splint are always stationary. The three-layer co-extrusion thin-blown production line adopts a new type of high efficiency and low energy consumption extrusion unit, IBC bubble internal cooling system, +360 degree horizontal upward traction rotary 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, good plasticization, low energy consumption and simple operation. It thoroughly solves the problems of film lotus leaf edge and winding head, and makes the product quality to a new level.
