Production Process Of Film Blowing Machine

The principle of the film blowing machine adds dry polyethylene particles to the lower hopper,and enters the screw from the hopper by the weight of the particles.When the pellets contact the thread bevel,the rotating bevel faces the plastic and is perpendicular to the bevel.The pushing force pushes the plastic particles forward.During the process,due to the friction between the plastic and the screw,the plastic and the barrel,and the collision and friction between the particles,it also gradually melts due to the external heating of the barrel.The molten plastic is filtered out by the machine head to remove imflated through the herringbone plate,the traction roller,and the winding of the finished film into a tube
