What is the function of the components of the film blowing machine?
The film blowing machine is mainly composed of an extruder, a machine head, a die, a cooling device, a foam stabilization frame, a herringbone plate, a traction roller, a winding device, and the like.
1 The extruder is responsible for melting, plasticizing, and extruding the resin, mainly affecting the plasticization of the film.
2 The inside of the machine head is a spiral body, which is responsible for the cross mixing of the plastic, which has an influence on the tensile strength and strength of the film.
3 die control membrane inflation ratio, on the film strength, stability, etc., generally 1:3.5
4 The cooling device is responsible for cooling the bubble, which has a great influence on the film strength, as well as stability and brightness.
