The main components of a blown film machine include an extruder, die head, stencil, cooling system, bubble stabilizer, traction auxiliary equipment, winding device, and other auxiliary equipment.
Extruder: Composed of a screw, barrel, and hopper, it melts plastic raw materials into a molten material.
Die Head: Includes a filter screen and filter plate to filter impurities and ensure the purity of the melt.
Die Head: Employs a spiral structure to extrude the melt into a continuous film.
Cooling System: Includes a cooling air ring and blower to regulate film temperature and control film thickness and uniformity.
Bubble Stabilizer: Utilizes an adjustable structure with sizing rings and rods to stabilize the film bubble shape for easier subsequent processing.
Traction Auxiliary Equipment: Composed of a traction frame, herringbone plate, and traction rollers, it pulls the film. The herringbone plate's angle can be adjusted according to the blown film specifications.
Rolling Device: Responsible for winding the film into rolls for easy storage and transportation.
Other Auxiliary Equipment: Such as air compressors, blowers, machine frames, and electrical control boxes, providing necessary compressed air, driving traction, machine support, and electrical control.
