Explain the daily maintenance and maintenance of the blow molding machine

Blow molding machine feeding position without feeding: several situations need to be checked: whether there is no material in the hopper, suppose it is: the need for quick feeding is not: please check whether the blow molding machine control contactor is energized, suppose it is energized, Quickly check whether the motor is energized and loaded.

In this case, it is likely that the preform (embryo) is stuck in the progress belt, and the simple method at this time is to assist the progress manually. Assuming that the control contactor of the blow molding machine is not energized, please check whether the preform detection electric eye and the reflector are not in the same straight line.

Feeding old card feeding tray: This situation is a headache. From experience, assuming that the length of the preform (blank) is longer and the weight is larger, then this phenomenon is relatively rare. The mold should be opened, and the mold should be opened and closed manually, assuming that it is normal, and working under empty working conditions, assuming that it is also normal.

Please check your exhaust time setting. Assuming that the exhaust setting is normal, and if you only need to blow the bottle each time, then it can be judged as the problem with the exhaust valve of the blow molding machine. Please open the exhaust valve to check its tension spring. And the situation of the seals (another phenomenon of this shortcoming is that the exhaust movement is relatively large or there is a movement that is not clean).

Suppose you are encountering a situation where many molds are normally produced and occasionally come to the mold cannot be opened. Please check whether the clamping pin has a segmented screw in it. Others, please check whether the clamping force is too large. If it is too large, please follow Standard re-adjustment.
