Bottle Blowing Machine Repairment and Maintenance

Equipment maintenance and care

Most equipment failures are caused by neglecting maintenance and lack of regular inspections. In addition to avoiding accidents, careful maintenance and regular inspections also play an important role in extending the service life of equipment.

1.The partition should be waterproofed regularly

2.Add xx grade mechanical oil into the oil mist collector, check it regularly, and add oil when there is no oil.

3.Check the travel switch frequently

4.If the equipment is found to be operating disorderly or a single action fails during operation, the equipment should be stopped to check the cause.

5.Keep the device clean and protect internal components from damage

6.The sealing ring should be replaced in time if it is damaged

7.Lubricate moving parts

8.Check the bolts of each component regularly to see if they are loose and correct them.

Abnormal phenomena and treatment methods

1.Q: Bottle mouth agglomeration (similar to crescent shape)
A: Increase the voltage of the first-stage heater, touch the preform with your hand after it leaves the drying oven to see if it is soft and hard enough, and reduce the delay blowing time until the agglomeration at the bottle mouth disappears.

2.Q: There is a hard lump on the bottom of the bottle (similar to a crescent shape)

A: Reduce the voltage of the first-level heater, increase the temperature of the infrared lamp near the bottom of the preform, and touch the preform with your hand after blowing it out to see if it is soft and hard enough. At the same time, reduce the delay blowing time until the hard lump on the bottom of the bottle disappears.

3.Q: There are lumps at the mouth and bottom of the bottle.

A: Please increase the temperature of the infrared lamp at the neck and bottom of the preform, and reduce the temperature of the infrared lamp in the middle part. Feel the feel of the preform according to the above method, and appropriately reduce the delay blowing time.

4.Q: Bottle inflation

A: This phenomenon indicates that the preform temperature has not reached the required temperature, so please increase the temperature of the entire heating zone.

5.Q: The preform is stretched but not formed

A: Check whether the high-pressure blowing valve is open, increase the blowing time, increase the blowing pressure, and check whether the overall temperature of the preform is not high enough.
