Defined
Film blowing machine is heated to melt the plastic particles blown film.
Film blowing machine a variety of points, PE, POF, PVC, and so on.
Blown out with the new particle is a new material, the color, the clean, bags stretch.
It was also made from recycled plastic bags made of particles, such particles are generally called old material, made of particles usually gray in color, usually want to add when the bag is made of pigment, bags made of uneven coloring, brittle and easily broken , the price is lower.
Although the recycling of plastic bags garbage plastic waste bags are generally making process and in the usual sense there are still a lot of difference.
Composition:
The composition of the film blowing machine by
① motor motor,
(2) screw and barrel,
(3) mold head Die head
④ inverter Inverter,
⑤ v board,
(6) on the wheel,
(7) flat pulley,
⑧ round 2,
⑨ winding wind
The raw material LLDPE and LDPE temperature is 160 - 180 degrees
The HDPE the temperature is 210-230 degrees
Film blowing machine is the most important thing is the three factors
Temperature (machine temperature, indoor temperature)
Two spirochetes
Three cooling system
Application:
Film blowing machine production film suitable for a variety of high-end film packaging. This film barrier, preservation, moisture-proof, anti-frost, oxygen barrier, oil, and can be widely used for light and heavy packaging. Such as a variety of fresh fruits, meat, pickles, fresh milk, liquid beverage, pharmaceutical and other supplies.
But it is not to do with garbage plastic raw materials, plastic particles as raw material
Right method of application:
1. intact, check the temperature-controlled heating appliances in good condition, pay attention to timely adjust the heating temperature of the points in the target zone.
2. check the traction speed control of film thickness.
3. observation adjust the film thickness uniformity, folding diameter standard.
4. Check the air cylinder reservoir pressure is not too high, but there should be standby pressure.
5. check the ratio of raw materials and mix.
6. check whether the raw materials and impurities, in particular, should be promptly mixed with a magnet to check iron.
7. check gear box bit and air compressor cylinder lubricating.
The periodic inspection
8. run the motor temperature rise and mechanical transmission case.
Film blowing machine using Notes:
1. operate the machine operator can not stand in the front, so as not to the unexpected hurt the operator. Raw material feed to prevent a hard object fall into the barrel with metal impurities and operation of small tools, such as damage to the machine. Prohibit the operation of rotating machinery with gloves, in case involved injuries.
2. check processing good gear box, air compressor lubricants, check the mechanical transmission parts lubrication. Avoid dried up operations damage to the machine and noise.
3. boot operation must check each power supply wiring is disconnected leakage; Inspect the instrument for damage not normal. Before booting the system to ensure the safety of the various components of normal, so as not to affect the production and cause an accident.
4. within the range of the film formation conditions, to improve the molding temperature, the cooling air temperature and blow ratio; film turbidity increases, the reduction in gloss; enhance the contrary.
5. die mouth discharge uniform to wear gloves slowly pulling the tube while the tube ends closed, slightly moved into the gas control valve, put a small amount of compressed air from the center of the mandrel hole, and then carefully to lead stable foam frame, the word board, and penetration of the traction roller, guide roller until the take-up (such as embossing to go through the embossing roll)
Inflation tube
6. compressed air pressure should be appropriate, neither tube can rupture, but also to ensure the stability of the symmetry of the film tube to ensure the quality of the production.
Extruder and die mouth
7. cleanup using copper knives, rods, or compressed air cleaning, but should not damage the smooth surface of the screw and screw.
