1 No feeding at the feeding position: several situations need to be checked:
  Is there no material in the hopper, if it is: need to add material as soon as possible
No: Please check whether the control contactor of the hoist is energized. If it is energized, quickly check whether the motor is energized and loaded, because in this case it is likely that the preform (embroid) is stuck in the lift. With, the easiest way at this time is to help raise it manually.
   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.PET bottle blow molding machine
  2 Feeding old card feeding 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 After the bottle is blown, it cannot 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 it fails every time you blow the bottle, 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 phenomenon of this kind of 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 produced normally 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.
