temperature (machine temperature, indoor temperature) Dipolar III
application of cooling system: the film blowing machine produces film, which is suitable for all kinds of high-grade film packaging
The film can be widely used in light and heavy packaging because of its good barrier, fresh preservation, moisture prevention, frost prevention, oxygen isolation and oil resistance
Such as all kinds of fresh fruits, meat food, pickles, fresh milk, liquid drinks, medical supplies, etc However, it does not use waste plastics as raw materials, but plastic particles Correct usage: film blowing machine: 1
Check that the temperature self-control is intact and the heating appliance is intact
Pay attention to timely adjust the heating temperature of each point within the index range 2
Check the traction speed and control the film thickness 3
Observe and adjust the uniformity of film thickness, and the folding diameter meets the standard 4
Check the air storage cylinder pressure, which shall not be too high, but there shall be standby pressure 5
Check and control the proportion of raw materials and mix them evenly ⒍ check the raw materials for impurities, especially check the mixing of iron with magnets in time ⒎ check the lubricating oil of reduction gearbox and air compressor cylinder 8
Regularly check the temperature rise and mechanical transmission of each running motor Precautions for the use of film blowing machine: 1
When operating the machine, the operator cannot stand in front to avoid accidental injury to the operator
During feeding, strictly prevent the hard objects that damage the machine such as metal impurities and operating gadgets in the raw materials from falling into the barrel
Do not wear gloves when operating the rotating machine to prevent injury caused by entanglement
　  2
Check and add the lubricating oil in the reduction gearbox and air compressor, and check the lubrication of mechanical transmission parts
Avoid dry operation, damage to the machine and noise
　  3
When starting up, check whether the wiring of each power supply is disconnected and leakage; Check whether the instrument is damaged or abnormal
Before starting up, ensure that all parts are safe and normal, so as not to affect production and cause accidents
　  4
Within the range of film forming conditions, increase the forming temperature, cooling air temperature and expansion ratio; Then the film turbidity increases and the gloss decreases; On the contrary, improve
　  5
When the die outlet discharge is uniform, wear gloves and slowly lift the tube blank
At the same time, close the end of the tube blank, slightly open the air inlet regulating valve to put a small amount of compressed air from the central hole of the mandrel, and then carefully guide it through the foam stabilizing frame and herringbone plate, and thread it into the traction roller and guide roller until coiling (if embossing is required, it shall pass through the embossing roller) ⒍ the compressed air pressure of the expanded tube blank shall be appropriate, which can not break the tube blank, but also ensure the symmetry and stability of the membrane tube, so as to relatively ensure the production quality
　  ⒎ copper knife, rod or compressed air can be used to clean the extruder and die mouth, but do not damage the screw and the smooth surface of the screw (1) production process and production principle: add dry polyethylene particles into the lower hopper and enter the screw from the hopper by the weight of the particles
When the particles contact with the inclined edge of the thread, the rotating inclined edge generates a thrust perpendicular to the inclined edge face of the plastic to push the plastic particles forward
In the process of moving, due to the plastic and the screw The friction between the plastic and the barrel and the collision and friction between particles are also gradually melted due to the external heating of the barrel
The molten plastic is filtered by the machine head to remove impurities
It comes out of the die mouth of the die head, is cooled and expanded by the air ring, and is wound into a cylinder through herringbone plate, traction roller and winding (2) the main structure of the film blowing machine is mainly composed of extruder, head, die head, cooling device, foam stabilizing frame, herringbone plate, traction roller, coiling device, etc
1: Extruder: the extruder is mainly composed of screw, barrel, hopper, deceleration and driving motor
The driving motor adopts electromagnetic speed regulating motor (or frequency conversion ordinary motor), which drives the reducer through belt drive to make the screw rotate in the barrel; When the plastic particles in the hopper are heated externally, the molten plastic is squeezed from the die mouth of the die through three-way Filtration 2
The machine head is composed of filter screen, filter plate and machine head gland
In order to adapt to the production of plastic raw materials containing more impurities, the unit adopts the right angle machine head structure with large filtering area
At the same time, considering the high power viscosity of high pressure, low pressure, mixture and recycled materials, the flow channel design of materials is reasonably selected, The drive motor of the extruder is used to extrude the filter plate, so it can adapt to a separate screen change operation 3: Die head the unit adopts advanced spiral die head structure
According to the particularity of high pressure, low pressure, mixture and recycled polyethylene materials, the main technical parameters such as spiral angle, back slope angle, setting angle length and die opening are designed
After many comparative tests, it is optimized and finalized
It has large internal pressure, stable and uniform extrusion and good film strength performance, No stitching and good matching with the extruder of the unit; At the same time, when exchanging the proportion of high and low pressure polyethylene, mixture and recycled material for film blowing production, the die head can not be replaced; Various die heads can be prepared according to the needs of users, and the replacement operation can be completed by one person, which is simple, safe, convenient and fast 4: The cooling device is composed of cooling air ring, air duct, blower, etc
5: Traction consists of traction frame, herringbone plate, traction roller, coiling mechanism, traction motor and other main components 6: Generally, the electrical control unit is equipped with unit operation cabinet
The main button is used to turn on the main power supply and turn on the main switch of the motor
The electric heating of the body, tee and each button of the die can be controlled respectively through the sub button switch
The two groups of coils in the key part adopt thermocouple automatic temperature measurement and automatic temperature control
In the normal production process, the temperature can be controlled automatically to ensure the stability and reliability of the production process
There are many kinds of film blowing machines, such as PE, POF, etc The new material is blown out with brand-new particles
The color is all weighed, clean and the bag is stretched well
　  Some people also use recycled plastic bags to make particles, which are generally called old materials
When making particles, they are usually gray
Pigment is usually added when making bags
The colors of bags are uneven, brittle and easy to break, and the price is low ⑶ although the purpose of the film blowing machine is recycled plastic bags, it is generally waste bags in the process of bag making, which is very different from garbage plastics in the general sense
　  　　  The film blowing machine is suitable for all kinds of high-grade film packaging
The film can be widely used in light and heavy packaging because of its good barrier, fresh preservation, moisture prevention, frost prevention, oxygen isolation and oil resistance
Such as all kinds of fresh fruits, meat food, pickles, fresh milk
