The three-layer co-extrusion blow-thinning production line adopts a new type of high-efficiency and low-energy-consumption extrusion unit, IBC film bubble internal cooling system, ±360° horizontal upward traction and rotation system, photoelectric automatic deviation correction device, automatic winding and film tension control, computer screen automatic Advanced technologies such as control systems. Compared with similar equipment, it has the advantages of higher output, good product plasticization, low energy consumption, and simple operation. It completely solves the problems of film ruffles and rewinding size, and brings product quality to a new level. The produced film has high transparency, puncture resistance, high toughness, good low-temperature heat-cutting properties, good composite fastness and anti-curling properties. This kind of film can be widely used in light and heavy packaging due to its good barrier properties, freshness, moisture resistance, frost resistance, oxygen barrier and oil resistance. Such as various fresh fruits, meat products, pickles, fresh milk, liquid beverages, medical supplies, etc.

Precautions for use:
1. The operator cannot stand in front of the machine when operating the machine to avoid accidental injury to the operator. When feeding, strictly prevent the hard objects that contain metal impurities and operating gadgets from falling into the barrel of the machine. It is forbidden to wear gloves when operating the rotating machine to prevent getting involved and injured.
2. Check and add the lubricating oil in the gearbox and air compressor, and check the lubrication of the mechanical transmission parts. Avoid dry operation damage the machine and make noise.
3. Before starting the operation, you must first check whether the power supply wiring is disconnected or leaking; check whether the instrument is damaged or not. Before starting the machine, ensure that all components are safe and normal to avoid affecting production and causing accidents.
4. Within the range of film forming conditions, increase the forming temperature, cooling air temperature and blow up ratio; then the turbidity of the film will increase and the gloss will decrease; vice versa.
5. When the die outlet is uniform and uniform, you can slowly pull up the tube blank while wearing gloves, and at the same time, close the end of the tube blank and slightly open the air intake regulating valve to put a small amount of compressed air into the center hole of the mandrel. Carefully guide through the foam stabilizer and herringbone, and penetrate the traction roller and guide roller until it is taken up (if embossing, it must pass through the embossing roller)
6. The compressed air pressure of the inflated tube blank should be appropriate, not only can not break the tube blank, but also ensure the symmetry and stability of the membrane tube, and relatively ensure the quality of production.
7. When cleaning the extruder and die, you can use copper knives, rods or compressed air to clean, but do not damage the screw and the smooth surface of the screw.
