How to operate high speed blown film machine correctly?

High-speed film blowing machine installation notes

When the film blowing machine is installed, care should be taken to adjust the center line of the extruder head and the center of the pulling roller to keep horizontal and vertical, and not to deviate from the skew. When winding up, gradually increase the outside diameter of the winding. Please pay attention to the cooperation between the pulling speed and the winding speed. Please adjust it in time. After the host is turned on, pay close attention to the operation of the host, timely adjust, correct, electrical instrument, controller to ensure its normal operation. Mainframe gearboxes and traction reduction gearboxes should be frequently refueled to replace gear oils. The new machine should be replaced with a new gear oil in about 10 days to ensure normal operation of the rotating parts. Pay attention to refueling to prevent jamming and overheating damage. Also check each one. The tightness of the connection prevents loosening of the bolt. The compressed air in the blister tube should be kept in proper quantity, because the compressed air will be leaked out during the traction process. Please add it in time.

First of all, regardless of the number of equipment, there must be two or more shifts per shift. This is related to the safety of production and should not be taken carelessly.

Films blown below 1200mm can be kept unchanged for 2 people per class in 3 machines (The principle is that the machine needs to be configured, and it is best to configure the feeders together). If there are six machines, each class can be configured with 3-4 individuals, it should be able to meet the needs of the specific look at their own row.

1. If the equipment is not heated, the heating temperature and time are less than the specified requirements, the extruder and rotating die must not be started, otherwise the equipment will be damaged.

2. When the raw material is unpacked, check whether there is wet material. The wet material must not be mixed. It must be dried after drying.

3, die and die mouth cleaning can only use copper to clean the die mouth, not scraping knife blade, iron scrape die mouth, otherwise it will cause die damage.
