Share the maintenance of the blow molding machine

Step 1: Place the preform in the preform container and manually enter the preform positioning device through the conveying device.
Step 2: Put the preform mouth up and automatically load the preform onto the preform holder, and then send it to the drying tunnel.
Step 3: After heating, the preform is sent to the blowing and stretching platform, and then the mold is locked, followed by low-pressure blowing and high-pressure blowing, exhausting, and finally opening the mold.
Step 4: The finished bottle is taken down from the bottle blowing platform by the manual demoulding system.

Such as: 1 No feeding at the feeding position: Several conditions need to be checked:
Whether the hopper is out of feed, if it is: Need to fill up quickly
Never: Please check whether the control contactor of the hoist is in the energized state. If it is in the energized state, quickly check whether the motor is energized and loaded. In this case, it is very likely that the preform (preform) is stuck. The easiest way at this time is to naturally help the lifting belt.
If you check that the control contactor of the hoist is never energized, please check whether the preform detection electric eye and the reflector are never on the same straight line.
2 Feeding old card feeding tray: This situation is a more headache problem. From experience, if the length of the preform (preform) is longer and the weight is larger, then this phenomenon is less.
3 After the bottle is blown, it must not be taken out of the mold.
The mold should be opened first, and the mold should be opened and closed 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 if the two blows fail every time, then it can be judged that the exhaust valve is the problem. Please open the exhaust valve to check the condition of its spring and seal (this Another kind of failure is that the exhaust sound is loud or there is a sound of dirty exhaust).
If you are encountering a situation where many Lie algebras are produced normally and accidentally, the mold cannot be opened. Please check whether the clamping pin has a screw in it. In addition, please check whether the clamping force is very large. If it is too large, you should follow The standards are adjusted again.
