1 The bottle of the automatic blow molding machine cannot be taken out of the mold after blowing.

First, open the mold and open and close the mold manually. If it is normal, run it in an empty running state, if it is normal.

Please check your exhaust time setting. If the exhaust setting is normal, and the problem is caused by blowing the bottle every time, then it can be judged that it is a problem with the exhaust valve. Please open the exhaust valve to check its spring and seal. (there is another phenomenon of this problem is that the exhaust sound is relatively large or there is a sound of unclean exhaust).

If you encounter a situation where the mold cannot be opened occasionally due to the normal production of a lot of molds, please check whether the clamping pin has some screws in it, and also check whether the clamping force is too large, if it is too large. Probably re-adjusted according to the specification.


2 The bottle of the automatic blow molding machine is always pinched.

Is the position of the manipulator misplaced?


3 Two manipulators collide.

This situation requires manual reset of the manipulator from scratch, which is caused by misalignment.


4 The feeding position of the automatic blow molding machine does not feed, and several conditions need to be checked:

Is there no material in the hopper now, if so: need to feed quickly.

If No: please check whether the control contactor of the hoist of the automatic blow molding machine is powered on. If it is powered on, check whether the motor is powered on and loaded as soon as possible, because this state is likely to be caused by the preform ( The embryo) is stuck on the lifting belt, and the easiest way at this time is to manually assist the lifting.

If the control contactor of the hoist of the automatic blow molding machine is not energized, please check whether the preform inspection electric eye is not on the same line as the reflector.


5. Feeding the old card feeding tray of the automatic bottle blowing machine: This situation is a question of comparison headache. From the experience, if the length of the preform (embryo) is larger than the length of the cut, then this phenomenon is relatively small.
