The supplier of the automatic bottle blowing machine will tell you the common problems and troubleshooting solutions when blowing bottles. Burst.
Reason: 1 Due to the high temperature, the bottom of the bottle is too thin. 2. The blowing time is too short.
Solution: 1 Adjust the temperature at the bottom of the bottle 2 Extend the time for delayed blowing
The dividing line is flat.
The reason is that during the blowing process, the gas cannot be discharged from the exhaust hole in a timely manner, and the thin layer of material forming the bottle wall blocks the exhaust hole
Solution: 1 Correct adjustment of mold clearance 2 Control the air flow rate with a high-pressure air valve 3 Improve design structure
There are wrinkles at the bottom.
Reason: The blowing pressure of the outer wrinkles is not enough, and there are too many stretching rods, which press down the material;
Internal wrinkles are very common. The head end of the bottle preform is overheated or the stretching pressure is delayed at the beginning.
Solution: 1 Ensure that the blowing time on the mold is consistent and stable. 2. Do not overheat the head end of the bottle preform. 3. Ensure that the delay time from stretching to entering blowing 1 is not too long.
Hot bottle.
The reason is that the bottle is overheated, causing recrystallization inside or outside the preform, resulting in bottle explosion
Solution: 1 Excessive stretching time 2 Lower the position of the cooling plate
Segmental weight unevenness (excessive neck length).
Reason: 1. The stretching rod stretches from bottom to top and gradually cools. The material is very thin, and the cooling speed is increased.
Solution: 1 Adjust the position of hotspots and solve the problem of the main body of prefabricated components Adjusting the position of the cooling plate
Eccentricity at the bottom.
What is the reason? 1. Transportation and alignment issues 2 The back door is not aligned with the bottle
Solution: 1 Adjusting the conveying and alignment of bottle preform molds 2 The pressure setting of the stretching rod is too low
3. The pressure of blowing bottle 1 is too high and too early. 4. The setting of the stretching rod pad is not appropriate.
Jewelry - with hair on the feet.
Reason: The root cause is the cold bottle. Stretching beyond the natural stretching limit directly leads to stretching of the surrounding structure of the bottle.
Tearing, the tearing point formed becomes a visible pearl after reflection.
The supplier of the automatic bottle blowing machine tells you the solution: 1 Ensure that the bottom of the bottle is in the middle position; 2. Reduce the speed of the bottle blowing machine;
