In order to obtain plastic bag products with controllable quality in the process of ABA film blower, it is necessary to control all processing links in place. Under normal circumstances, the process of film blowing machine is divided into feed heating, traction and control of compressed air. The size of plastic bags is controlled by how much air is blown, and then the film is stabilized by a film stabilizer. Drawing device of film blower adopts sprayed steel plate herringbone, new type of deceleration and frequency conversion motor, cold pressing pitting point, new type adjustable edge inserter, automatic air filling, LED photoelectric indicator device. Film-forming characteristics: film uniformity, neat insertion edge, pressing pits good-looking, beautiful, neat and film-forming thick, large.
Start each extruder at low speed, observe whether the starting current is normal, and then slowly increase the speed of the extruder. Turn on cooling fan, compressed air, upper traction roller and corona processor. When foaming, the upper traction pinch roll should be opened. After the material head passes through the upper traction pinch roll, the upper traction pinch roll should be clamped. When the bubble is pulled, the corona processor should be turned on, and then the electrical corona machine will be closed after the material passes through the corona machine. Film bubbles are blown with compressed air to the required width of product specifications, and the width of trimming should be controlled within 20 mm. The film bubble passes through the lower traction and enters the winding device to carry out the winding. Adjust the speed of the upper traction, the lower traction and the winding, and control the thickness of the thin film. Start the die rotation.
When the thickness and width are normal, close the power switch of corona processor and adjust the voltage and current of corona processor. It is required to ensure that the intensity of corona treatment on the film surface is greater than 40 dynes. When the thickness and width of the film are normal, the film is divided into slices and rolled. The front and back slices of the film are separately rolled on different rollers for normal production.
