LDPE: 0.001-0.2mm HDPE: 0.012-0.15mm
Two colors, more colors can be designed
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
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.
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 extrudeding out section, which makes the swirl material turn into the advection by the filter screen in the equipment head. Then ,the materialgoes into the spiral machine head and flows into the die opening. At the last it gets into the film 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.
On the condition of certain extruding machine rotating, the instant temperature and the changeless material discharging, the width is decided by the ratio of blowing out,it is easily operated to control the times of film’s transversed drafting from 3 to 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.
Cooling and finalizing the design
Cooling vane and air pressure decide the final design ,making the film tube extrude out from die opening and the plastics cooled on the basis of the designed shape and it is adjusted in fine,bringing the more correct section and brightness surface,After finishing shape, the material passes the drafting roll and comes into printing system.
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 adopts 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, as a result, the printing fastness is 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 the slowdown of the worm wheel and worm is large it can lock itself). Through the mechnism driving, the printing speed can be adjusted between 8~40 meter/min, at your optional.
Between the front chromatography and the back chromatography the oven drying is used to ensure the ink drying good quality. The time of ink drying effects the quality of products directly.
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.
Double friction rewinders and cutting device are adopted on this machine to produce the single layer film and double rounded film in accordance with clients'needs.It could twin rewind in sigle ayer or rewind in twin layers.The film is rewinded smoothly.
