How to use the blown film machine correctly?

Matters needing attention when installing the blown film machine:

When installing the blown film machine, care should be taken to adjust the center line of the extruder head to be horizontal and vertical with the center of the pulling roll, and must not deviate from the skew. When winding up, the outer diameter of the winding is gradually increased. Please pay attention to the matching 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, and timely adjust, correct, and electrically instrument and controller to ensure its normal operation. The main gear box and traction reducer should be refueled frequently, and the gear oil should be replaced. Please replace the new gear oil with the new machine for about 10 days to ensure the normal operation of each rotating part. Pay attention to refueling to prevent jamming and overheating damage. Also check each The fastening of the joints prevents the bolts from loosening. The compressed air in the bubble tube should be kept in an appropriate amount, because the compressed air will be leaked out during the traction process, please replenish it in time.

The film blowing machine is generally operated by several people:

First of all, no matter how many equipments, there must be more than 2 people on duty per shift. This is related to the safety of production. Don't care.

Blown film of 1200mm or less, can keep 2 people per shift below 3 machines (the principle is to configure the mixer, it is best to configure the feeder together). If there are 6 machines, each class can be configured with 3-4 people, it should be able to meet the needs, specifically to see their own arrangements.

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

2. When the raw materials are opened, check whether there is wet material. The wet materials should not be mixed. It must be dried after drying in the drying room.

3. When the die and die are cleaned, only the copper piece can be used to clean the die. Do not use a blade or iron to scrape the die. Otherwise, the die will be damaged.

4, the film blowing machine guide roller, including rubber roller and winding roller, can not be cut with a blade, otherwise it will cause the roller to scratch.

5. The filter and corona treatment machine of the extruder must be periodically changed for filtration and cleaning. Generally, it is required to replace the filter and clean the silicone roller of the corona treatment machine with alcohol within 24 hours to 48 hours. Filter specifications: a two-layer 80 mesh, one-layer 100-mesh three-layer filter.

6. The corona treatment machine guide roller does not open the corona treatment machine without film walking. Once the film is broken or stopped, the corona treatment machine should be turned off urgently to avoid the corona treatment machine burning out.

7, no corona treatment or corona treatment film that does not reach 38 dynes or more must not be placed in the finished product, otherwise it will cause a major accident of composite quality.
