Frequency conversion application of film blowing machine
Release time：2024-06-06
The dry polyethylene particles are added into the lower hopper, and the weight of the particles themselves enters the screw from the hopper. When the particles contact with the inclined edge of the thread, the rotating inclined edge generates thrust perpendicular to the inclined edge on the plastic, pushing the plastic particles forward. During the pushing process, due to the friction between the plastic and the screw, the plastic and the barrel and the collision friction between the particles, at the same time, it is also gradually melted due to the external heating of the barrel. The molten plastic is filtered by the machine head to remove impurities from the die mouth of the die head, cooled by the air ring, blown through the herringbone plate, traction roller, and wound to roll the finished film into a cylinder.
