Maintenance of Bottle Blowing Machine

Views: 647 Author: Site Editor Publish Time: Origin: Site

In the process of using the blow molding machine, we usually encounter some difficulties, which causes the machine to fail to operate normally. This requires us to pay attention to the maintenance of the bottle blowing machine during the usual operation.


I will elaborate for you below:

1. No feeding at the feeding level

Several situations need to be checked: whether the hopper is out of feed, if it is, it needs to be fed as soon as possible. If not, please check whether the control contactor of the hoist is energized. If it is energized, check whether the motor is energized and loaded quickly, because this situation is likely to be stuck by the preform (preform) Lifting belt, at this time the easiest way is to manually help lift.


If you check that the control contactor of the hoist is not energized, please check whether the preform detection electric eye and the reflector are not in the same straight line.

2. Feeding old card feed tray

This situation is a headache. From experience, if the length of the preform (preform) is longer and the weight is larger, then this phenomenon is relatively rare.


3. The bottle cannot be taken out of the mold after being blown

First, you should open the mold, open and close the mold manually, if it is normal, run it in the dry running state, if it is also normal.


Please check your exhaust time setting. If the exhaust setting is normal and it fails as long as you blow the bottle each time, then it can be judged that the problem is with the exhaust valve. Please open the exhaust valve to check the condition of its spring and seal (this Another phenomenon of this failure is that the exhaust sound is relatively loud or there is a sound of dirty exhaust).


If you encounter a situation where many molds are normally produced and accidentally cannot open the mold, please check whether the clamping pin has a segmented screw in it. In addition, please check whether the clamping force is too large. If it is too large, you should follow Standard readjustment.


4. The bottle is always pinched

Whether the position of the manipulator is misaligned.


5. Two manipulators collide

In this case, you need to manually reset the manipulator again, which is caused by misalignment.


Every time you encounter a problem, please read the above common problems and solutions carefully. Nancheng Machinery is online 24 hours a day, always on call to provide you with professional answers.
