Main feature and purpose:
This machine is used for the production of soft plastic bags, which can be printed on both sides simultaneously blowing and printing. The material is HDPE, LDPE, dissoluble plastic, biodegradable material and recycling material. This will be your best choice for production of shopping bags, vest bags and other plastic bags. We will provide you with a whole bag production line, including all kinds of bag making machine.
1. Wide application, several purposes ( It can blowing and printing at the same time, or single blowing and single printing);
2. Advanced structure, user-friendly operation, correct overprint, convenient maintenance;
3. Save raw materials, product quality is stable. It has the following features compared with the traditional process
A) Bright color, good fastness;
B) Blowing and printing at the same time. Correct overprint;
C) Easy maintenance, stable and reliable 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
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 heated through preheat section, plastifying section and extruding out measurement section. It is mixed by screw pole and 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 film tube is drafted out, the size of film should be controlled well and the main processes are the blowing out section and the lengthways drafting section.
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 of film is decided by the lengthways drafting time, i.e. The ratio between drafting speed and the extruding speed and normally 3~7 times. If the drafting ratio is too large, the film can easily broke out.
Cooling and finalizing the design
The design finalizing is mainly decided by cooling vane（air ring） of air pressure. Its function is to make the film tube extrude out from die opening. The plastics finalizing is according to the designed shape and it is adjusted in fine which makes the more precision section shape and brightness surface. After shaping, the material passes the drafting roll and comes 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 to 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 which uses 200~1200 rotates/min. The worm wheel and worm make the printing plate and roller rotating at the same speed (when worm wheel and worm is slow down the rate largely it can lock itself). By the mechnism driving, the printing speed is optional. It is adjusted between 8~40 meter/min.
Drying part
The oven drying is used between the front chromatography and the back chromatography, so can reach the ink drying quality and 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 that some surface of roll becomes blank and the depressed part is fulled with ink.Finally 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 adopt double friction rewinders and cutting device and It could produce the single layer film or double layers rounded film according to customers’ demands. It could double rewind in single layer and also single rewind in two layers，so the film should be rewinded smoothly.
