Main feature and purpose:
Along with the widely use of package film, the plastic film products are even more needed by people from day to day.Our factory collects over 30 years’ experiences to produce plastic machinery series, introduce the similar machines’ characters to produce this machine. The machine is special to blow film, such as HDPE, LDPE, dissoluble plastic and reproducible.
The machine is compact structure, easy operation, less occupation of space, it is the idea equipment to produce plastic film.
Step of the Film Blowing:
Feeding→plastifying→extruding→blowing out and extensing
→cooling and finalizing the design→traction→ traction →rewinding
Feeding Process
Just the equipment start, should put litter material. Until the material is extruded, the machine head is normal and the condition of plastifying is good, then add large quantities of material.
Plastifying process
The raw material goes out from the extruder and it is heated through preheat section, plastifying section and extruding out measurement section, mixed by screw pole, the grain material is plastified into fused mass.
The Extruding out process
The fused material output from the screw pole extruding out section makes the original swirl material becoming the advection through the filter screen in machine head. Then, the material comes into the spiral machine head and flows into the die opening, finally, it becomes the cylinder filming tube, extruded out. After the filming tube is drafted out, the size of film should be controlled well. The main processes are the blowing out and the lengthways drafting. Under the certain extruding machine rotating, the instant temperature and the changeless material discharging, the size (width of breadth ) is decided by the ratio of blowing out, which (the times of film’s transversed drafting ) is easily operated under 3 ~ 6 times.
The thickness of film is decided by the lengthways drafting time, i.e. the ratio between drafting speed and the extruding speed, normally it is 3~7 times. If the drafting ration is too large, the film is easily broken out.
Rewinding part
This machine adopt double friction rewinders and cutting device. It could produce the single layer film and double layers rounded film according to clients’ requirements. It could double rewind in single layer or single rewind in two layers. The film should be rewinded smoothly.
