Blow molding machine maintenance1
Blow molding machine maintenance 1. Feeding level does not feed: several situations need to be checked: whether there is no material in the hopper, if yes: need to feed quickly No: please check whether the control contactor of the elevator is in the energized state, if If it is energized, quickly check whether the motor is energized and loaded, because in this case, it is likely that the lifting belt is jammed by the preform (preform). At this time, the easiest way is to help lift 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. 2. Feeding old card feeding tray: This situation is a more headache problem. From experience, if the length of the preform (blank) 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. First of all, 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 springs and seals (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 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. Whether the position where the bottle is always pinching the manipulator is misplaced. 5. If two manipulators collide, you need to manually reset the manipulator again, which is caused by misalignment.
