       The working principle of the film blowing machine and its structure

       A film blowing machine is a mechanical device that heats and melts plastic granules then making film rolls. The working step is: dry polyethylene granules be added to the hopper, depend on the weight of the particles themselves from the hopper into the screw, when the aggregate after contact with thread oblique edge rotating slant edge face plastic produce and inclined faces the vertical edges of thrust, plastic granules move, goes on in the process, because the plastic and screw, plastic and barrel friction between the friction and collision between particles, but also gradually melt due to external heating cylinder. The molten plastic is filtered through the head of the machine to remove the impurities from the die, through the wind ring cooling, blowing through the collapsing plate, traction roll, and winding the finished film in a roller

      The main structure of the blowing machine

      It consists of extruder, head, die head, cooling device, stabilizer, collapsing plate, traction part, coiling device, etc.
