Comprehensive list of automatic bottle blowing machine faults

According to the inquiry on Maigou.com, the complete list of faults of the automatic bottle blowing machine is as follows:

1. The bottle mouth of the blown bottle is deformed: it is caused by the transfer chain of the preform during the heating process. The channel drives the bottle base to transmit the temperature to the preform mouth. During the heating process, the temperature continues to accumulate, and the bottle mouth expands and deforms. At this time, the air cooling or water cooling to the bottle mouth can be increased.

2. There is accumulation of material at the bottom of the finished empty bottle: it may be that the stretching rod is not adjusted in place. It is recommended that the stretching ratio between the preform and the bottle body is 1:2.5 (excluding the bottle mouth) part), while adjusting the heating temperature and extending the pre-blow. 3. There is no material in the supply layer of the bottle blowing machine: there is no material in the lower hopper or the control contactor of the elevator is not energized. At this time, you need to check whether the motor is energized and has no load, because the lifting belt may be stuck in the preform. Technical personnel should be contacted promptly for processing.

4. White bottom: The preform is too cold, over-stretched, pre-blowed too early or the pre-blow pressure is too high.

5. There is a magnifying glass at the bottom of the bottle: there is too much material at the bottom of the bottle or the pre-blowing is too late or the pre-blowing pressure is too low.

6. There are wrinkles in the bottom of the bottle: it may be that the bottom temperature is too high (the gate is not cooled well) or the pre-blowing is too late, the pre-blowing pressure is too low, and the flow rate is too small.

7. Partial whitening occurs: it is caused by excessive stretching during bottle blowing, the temperature here is too low, or the pre-blowing is too early, or the stretching rod is hit.
