In the installation of the film blowing machine, the center line of the extruder and the center of the traction roll should be adjusted so as to keep the horizontal vertical and not deviate from the deviation. Due to the gradual increase of winding outside diameter, please pay attention to the coordination of traction speed and winding speed, please timely adjust. After the main engine is opened, pay close attention to the operation of the main engine, adjust, modify, electrical instrument and controller to ensure its normal operation.

Host gear box, traction reducer should often come on, change gear oil, new in the use of 10 days or so, please change new gear oil, in order to ensure the normal operation of the rotating parts, pay attention to refuel, prevent damage of stuck and overheating, but should also check the connection parts of tight situation, prevent Luo Shuan is loose. The compressed air in the bubble tube should be kept in proper amount due to the leakage of compressed air during the traction process, please timely supplement.

The low density polyethylene film of the dalian blow molding unit is usually made of two processes: blow molding and flow delay. The thickness of the polyethylene film is symmetrical, but it is seldom used because of the high cost. Blown polyethylene film is made by blow molding machine blown by blow molding machine, the cost is low, so the application is most common. Low density polyethylene film is a semi-transparent, light and soft film with excellent chemical stability, heat sealing, water resistance and moisture resistance. It can be chilled and boiled. The stress is poorly insulated for oxygen, used in the inner membrane of composite flexible packaging material, and also the most prevalent, the current application dosage is one of the biggest plastic packaging film, about 40% of plastic packaging film consumption.

Plastic blown film machine is best of choose and buy yourself directly, because must not a small investment, the formal manufacturers will have a free pick up service, and accompanied him to explain, in the study of entity can not only understand the enterprise culture and the production situation, but also through to the enterprise to observe the effective objective influence make their own judgment to remove the outside world, will greatly reduce the risk of purchase.

Choose the plastic blowing film machine to see the manufacturer, then the brand. Have many years experience of why the manufacturer will also exist because there are in the market, the market is the customer, there is customer's product is relatively satisfactory for the customer, the quality of the products also have safeguard relatively. Secondly, according to the brand choice, the general mainstream brands have a good quality basis and are favored by customers.
