Design of High speed Forming of Structure of Fully Automatic High speed Blow Molding Machine


1. Fully automatic blow molding machine preform transfer structure: The unique preform mandrel transfer structure ensures that the preform is not at risk of being reversed during heating.


2. Fully automatic high speed bottle blowing machine with high-speed operation and clamping structure: the arc of the invention patent with independent intellectual property rights is a clamping structure, and a special clamping and pressurizing system, stable and noise-free high-speed operation.


3. Hot-filling bottle forming structure of automatic high-speed bottle blowing machine: when blowing hot-filling bottles, a three-way circulation type specially designed distributor is used to evenly distribute the water/oil temperature of different requirements to different parts of the mold, so that the bottle The crystallinity reaches the best effect.


4. Lightweight and energy-saving bottle blowing system: the double combination of cold air and hot air is used to forcibly cool the bottle mouth and the driving mandrel during heating to achieve the best cooling method. The air induction device is adopted in the heating box to overcome the air convection, ensure the balance of the heating temperature of the preform, and prevent the surface of the preform from overheating.


5. Energy-saving sealing machine air blowing combination valve: the control valve is connected by no pipeline, with compact structure, simple debugging and maintenance, reasonable high and low pressure gas consumption, and achieving the best energy consumption control.


Simple and reliable manipulator: cam link type manipulator for taking blanks and bottles, which is simple, excellent in coordination and low in manufacturing cost.


Closed-loop temperature control method; preform temperature feedback tracking temperature compensation; quickly reach a stable state of preform heating.


6. Clean and safe molding design: The 2l bottle blow molding machine adopts a fully enclosed structure, which ensures a clean molding environment, eliminates the pollution of the molding bottle from the outside world, and ensures the cleanliness of the molding of the large medical infusion bottle. The perfect and reliable safety door system ensures the safety of operators and the long-term operation stability of the pet bottle blowing machine.

Five things to pay attention to in the maintenance of the automatic pet blowing machine:


1 The bottle cannot be taken out of the mold after blowing.


1, the mold should be opened, and the mold should be opened and closed manually. If it is normal, run it in the dry 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.


2 The bottle is always pinched

Whether the position of the manipulator is misplaced.


3 Two manipulators collide

In this case, the manipulator needs to be manually reset again, which is caused by dislocation


4 No feeding at the feeding level: There are several situations to be checked:Whether the hopper has run out of material, if so: need to add material quickly

No: please check whether the control contactor of the hoist is powered on. 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 and lifted. Belt, at this time, the easiest way is to manually help lift.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.


5. 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.
