Main feature and purpose:
Soft plastic package bag can be produced by this machine,with printing on both side,this machine can blow and print at the same time.HD,LD,dissoluble plastic ,biodegradable material and recycling material are all raw material.It will becomes the perfect choice for you to produce the shopping bag ,vest bag and plastic bags.We also can provide the production line for the bag making machine,including the various bag making machine.
1.Wide application, several purposes serving (It can blow HDPE and LDPE, blowing and printing at same time or single blowing or single printing)
2.Advanced structure, easy operation, correct chromatography, easy maintenance
3.Raw material saving, reliable quality. It has following characteristics contrasting to traditional wheel print machine
a. Bright color, more fastness
b. Blow and color-print at same time, correct chromatography
c. Simple maintenance, reliable and stable quality
d. Less power consumption, less labor, work time saving, less cost
Step of the Film Blowing:
Feeding→plastifying→extruding→blowing out and extensing
→cooling and finalizing the design→traction→ corona treatment
→ printing → Drying → traction →rewinding
Feeding Process
Put litter material after the machine starts. Until the material is extruded well, confirm the machine head is normal and the condition of plastifying is fine,then can enlarge the quantities of the 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 is from the screw pole extruding out section. It makes the original swirl material become the advection through the filter screen in machine head and then the material comes into the spiral machine head and flows into the die opening. Finally it becomes the cylinder filming tube and extruded out.
The film's size will be controlled well once the film tube is elongated,it has two main processes, blowing out and the lengthways drafting.
Under the certain extruding machine rotating, the instant temperature and the changeless material discharging, also the dimension (width of breadth ) is decided by the ratio of blowing out and (the times of film’s transversed drafting ) can be easily operated under 3 ~ 6 times.
The thickness depends on the lengthways drafting ,i.e.the ratio is normally from 3 to 7 times between drafting speed and extruding speed.The film is easily broken out under the condition of the too large drafting ration.
Cooling and finalizing the design
The design finalizing is mainly decided by cooling vane(air ring) and air pressure. Its function is to make the film tube extrude out from die opening and the plastics cooled according the designed shape and it is adjusted in fine. The more precision section shape and brightness surface and after the shaped, the material passes the drafting roll, then coming into printing part.
Printing part
The technical flowing is as follows,
traction roller→electronic friction machine→first overprint→dry→second overprint →the same speed roller traction rewind.
The electric compact machine to treat the film
In this machine, the electronic friction machine is adopted to use the high frequency pulse high voltage, make the air bring ionization and the discharge phenomena. When the plastic film passes through the electric discharge space and bears the pulse arc stroke, the original smooth surface of film forms the pores which can be seen by the naked eye, so the printing fastness can be improved.
Printing speed adjustment
The motor is electrically moment motor,its rotate is from 200to 1200rotates/min.The printing plate and roller rotating is kept by the worm wheel at the same speed (it can lock itself when slowdown the worm wheel and worm).Through the mechnism,the printing speedcan be choosen from 8 to 40 meter/min with your needs.
Drying part
The oven drying is used between the front chromatography and the back chromatography to reach the ink drying quality. The time of ink drying effects directly the quality of products.
The lengthways and transverse adjustments of printing.
Because the plate shaft of machine is driven by guild adding straight gear, the transverse adjustment range of plate (Left and Right) is 50mm (adjusted by wheel), the lengthways (front and back) is adjusted by hand wheel to raise or fall down, the chromatography adjustment can be finished, it can be changed.
Printing roll, ink scraping and gravure processes
When printing roll was rolled in the ink channel, the whole cylinder is painted with thicker ink, then you can use the machine scraper, the scraper removes the thicker ink in printing chart. So, some surface of roll becomes blank and the depressed part is filled fully with ink, then under the press roll pressure, the ink at the depressed part (pattern) is transferred and printed to the surface of film.
Rewinding part
This machine applies double friction rewinders with cutting device and it could produce the single layer film and double layers rounded film according to customers’ demands. It could double rewind in single layer or single rewind in two layers, so that the film should be rewinded smoothly.
