The operation specification of three-layer coextruder film machine is explained

Three-tier co-extrusion blown film machine production line adopts the new type of high efficiency low energy consumption extrusion unit, the IBC film cooling system inside the bubble, + 360 ° for traction on the horizontal rotating system, photoelectric automatic correction device, automatic winding and film tension control, advanced technology such as computer screen automatic control system. Compared with the similar equipment, has a higher yield, good product plasticizing and the advantages of low energy consumption, easy operation, completely solve the film falbala and winding size top problem, make the product quality on a new step.

The produced films have high transparency, puncture, high toughness, low temperature, good compound fastness, and crimp resistance. This membrane is good for its obstructing, preservation, moisture-proof, frost proof, oxygen resistant, oil resistant, can be widely used in weight packaging. If all kinds of fresh fruit, meat, pickles, fresh milk, liquid beverage, medical supplies, etc.

Observe whether vesicular deformation rapidly, after the completion of such as have deformation should be timely adjusted, first check whether the die clearance is adjustable, stable foam board by membrane bubble, whether if there is no problem to check whether there is open the doors and Windows, found after timely treatment. Observe whether the membrane blisters are inclined, and if inclined, use baffle at once. Adjust the speed of the main motor according to the requirement of the production task, adjust the traction speed according to the thickness requirement. Open the rotate button to rotate the die head.

After being membrane bubble stability, was carried out on the thin film thickness and width measurement, see whether to reach the required standard, (if the thickness of the thick, adjust the die clearance or reduced wind ring air volume, make further blowing film, also can improve the traction speed appropriately so that its thickness thinning; if the thickness of the slant thin. Width with air pump to control). It also measures the width of the inserted film to meet the standard, if it does not meet the appropriate adjustment of the insertion plate to reach the qualified. To observe the degree of symmetry of the inserted film, whether there is a dislocation, if there is a dislocation, it should be adjusted in time.

Measure the shrinkage of the transverse longitudinal of the film to see if it is standard so that it can be adjusted in time. (e.g., transverse tensile strength is poor, should be appropriate to reduce traction speed, longitudinal tensile strength is poor, thin film can be appropriately reduce the temperature of the molten resin, or improve the drawing speed, increasing the wind ring air volume, make the membrane bubble fast cooling) after all normal, record the temperature range of the temperature data as well as the host and traction. Do your homework. After the winding diameter reaches the predetermined requirement, the rewinding will be carried out, the spool will be placed on the spool, and the shaft will be removed to the rewinding position to complete the winding. Record the temperature area every three hours, and record each scroll (volume time, weight, width, thickness deviation, shrinkage rate, waste weight)
