How to maintain and repair the blow molding machine

After the blow molding machine has been used for a period of time, irregular maintenance of the equipment may cause equipment failure and reduce efficiency. Therefore, it is necessary to regularly maintain and repair the equipment to effectively extend the service life of the equipment.

1. There is no material in the feeding layer: several situations need to be checked: whether there is no material in the hopper, if so: the material must be supplied quickly. NO: Make sure the control contactor of the hoist is powered. If there is power, quickly check that the motor is powered and unloaded, because in this case the lift belt may be stuck in the preform (preform). An easy way is to do this manually. Please help to lift. If it has been confirmed that the control contactor of the elevator is not energized, please check whether the electronic ophthalmic reflector for preform detection is not straight.

2. Feeding the old card to the paper tray: This situation is more troublesome, and according to our experience, if the length of the preform (blank) is long and the weight is large, this phenomenon is relatively rare.

3. After blowing the bottle, it cannot be taken out of the mold. Open the mold first, then manually open and close the mold. If normal, do a dry run. Check exhaust time setting. If the vent setting is normal and every blow fails, then it is certain that the vent valve is the problem.

Open the vent valve to check the spring condition and seal. (Another symptom of this failure is that the exhaust sound is relatively loud or the exhaust is dirty). Many molds are produced normally, so if the mold is opened by mistake, check whether the clamping pin has an opening screw. Also check for excessive clamping force. If it is too large, standard readjustment must be followed.
4. Whether the bottle always clamps the manipulator in the wrong position.
In short, in the process of using the blowing equipment, in order to use the equipment better, it is necessary to carry out equipment maintenance and regular inspection and timely maintenance in strict accordance with the prescribed work, so that the equipment can work better. Equipment efficiency.
