Common problems in the blowing process of the blow molding machine

1. Feeding the 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. 2. No feeding at the feeding level: There are several situations to check: 1) Whether the hopper has run out of material, if so: need to feed quickly; 2) If not: please check whether the control contactor of the hoist is energized. If it is powered on, quickly check whether the motor is powered on and loaded, because in this case it is likely that the preform (preform) is stuck on the lifting belt, and the easiest way is to manually lift it; 3), If the control contactor of the inspection elevator is not energized, please check whether the preform detection electric eye and the reflector are not in the same line. 3. Whether the position of the bottle is always pinched by the manipulator is misplaced. 4. The bottle cannot be taken out of the mold after blowing. 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 it is normal. Please check your exhaust time setting. If the exhaust setting is normal and it fails every time the bottle is blown, then it can be judged that it is the problem of the exhaust valve. Please open the exhaust valve to check the condition of its springs and seals (this There is also a phenomenon that the exhaust sound is relatively loud or there is a sound of unclean exhaust). If you encounter a situation where the mold cannot be opened by chance due to the normal production of many molds, please check whether the clamping pin has a segmented screw in it. In addition, please check whether the clamping force is too large. Standard readjustment. 5. Two manipulators collide: In this case, it is necessary to manually reset the manipulator, which is caused by dislocation.
