1. The plastic extrusion blow molding machine feeding machine does not feed: need to check several situations: Whether the hopper has no material, if it is: need to hurry to feed, if not, please check whether the control contactor of the feeder is in the power state, if It is in the state of power, and it is necessary to check whether the motor is in power and load state.
2. Feeding old card feeding tray: This situation is a headache problem. From the experience point of view, if the length of the preform (embryo) is relatively long and the weight is relatively large, then this phenomenon is relatively small.
3. The bottle cannot be removed from the mold after it has been blown. First, the mold should be opened, and the mold should be opened and closed manually. If it is normal, run it in the empty running state. If the automatic blow molding machine is normal. Please check your exhaust time setting. If the exhaust setting is normal and it will fail every time you blow a bottle, you can judge the problem of the exhaust valve.
