The correct operation mode of the three-layer extrusion film machine

Start the main motor, operate at low speed, melt the material extrude, the material is extruded and the gas pump is pumped, forming the membrane bubble. Then the fan is turned on immediately. (appropriately depending on the frost line of the membrane to adjust the air volume, the air volume is too large, and the air volume is too low to cool well. Put the membrane tube into the traction roll, and along the guide roller to the winding. 3. Observe whether vesicular deformation rapidly, after the completion of such as have deformation should be adjusted in a timely manner, to check whether the die clearance 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 tilted, such as tilting at once. Adjust the speed of the main motor according to the requirement of the production task notice, adjust the traction speed according to the thickness requirement. Turn the spin button to rotate the die head. 5. After being membrane bubble is stable, the film thickness and width measurement, look to whether meet required standards, (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) 6. At the same time, measuring the width of the interpolation film conformed to the standard, such as do not meet should be moderate adjustment board to make it reach the qualified. The degree of symmetry of the inserted film is observed, and the dislocations should be adjusted in time.

Dalian's three-layer coextruder film machine is a new product which is developed according to the market demand, and it is designed to absorb the advanced technology of similar products at home and abroad. Suitable for all kinds of high-grade film packaging. This membrane is widely used for weight packaging because of its barrier properties, freshness, moisture, frost, oxygen and oil. Such as fresh fruits, meat, pickled vegetables, fresh milk, liquid beverage, medical supplies, etc.
