Technology Development

Application of servo PLC system:

Adopted Omron motion controller system (integration module type), using the PTO (servo positioning module) system for high-

speed positioning, proximity sensors search the orbital target location, sending high-speed signals to the servo system. The

position of the track is detected online by the high precision rotary encoder built-in the servo motor, sending back informations

to the control system, finally, high-speed positioning is carried out by positioning module.

Application of the servo motor

The mould movement mechanism: Adopted the servo motor connect the gear box, synchronical transmission system is

adopted to fulfill the reciprocating up and down motion of the two hinge mechanisms on both sides of the mold hauled by two

linkage rods respectively. In this way, the two mold holding plates in the middle move oppositely or towards each other, which is

generally known as mold opening and closing. The hauling wheel driven by the servo motor makes clockwise rounds

continuously, reducing the power impact and the wearing, makes the mould clamping more smoothly. Each round leads to a

complete cycle of mold holding plates movement------open and close. Also the high pressure air supercharged mold locking

mechanism is applied which buffs the impact between mold plates and effectively protects molds. Besides, it does help to

reduce the visibility of parting lines on finished bottles. The servo motor driven mold movement mechanism is designed and

created upon rigid engineering simulation analysis, which ensures that the series of the mould motions are simple, accurate,

consistent and speedy, making cycle time 0.2~0.4 seconds.

Variable pitch mechanism: This mechanisam is adopted the servo motor to connect the screw directly, the screw turns a

round, the pitch was changed from 63.5mm to 190mm directly, ensures high speed and accurate perform handling between the

two mechanism.

Application of thermostatic heating system

The modularized control system is used in the thermostatic flask blank heating oven, which use infrared lamps and reflector for

heating preform. After setting the temperature value, the equipment can automatically adjust the output voltage according to the

rate without being affected by voltage fluctuation and environmental temperature change. At the same time, it is also cooled by

circulating air controlled by frequency converter, which can effectively guarantee the internal heating temperature and constant

temperature of the heating ovens, and make the surface of each preform and its internal temperature uniformly heated.

Moreover, the bottle rotates 360 degrees in the heating ovens, so that each side of the preform can be heated evenly, which

improves the yield of blown bottle and the adaptability range of the thick-walled preforms.

Easy Maintenance

Omron servo controller system (motion controller, modular) is connected with the machine via particular communicating

cables.The user can manage all the actions of the machine through the motion controller. Once the machine has a fault, the

man-machine interface will provide warning signals and fault diagnosis report to the operator, the operator can quickly find the

cause of the fault and troubleshoot as soon as possible through the fault display.

★ If the bottle is blocked/full in the air conveyor, the function of automatic stop feeding preforms can be set in the program

through photoelectric detection.

★ If the machine after blowing machine stops working for too long time, the heating lamp can be set with the function of

automatically reducing temperature, saving electricity consumption and avoid the excessive temperature in the heating seat.

(Temperature setting is set in touch screen)

Safety

The reciprocating parts of the bottle blowing machine are equipped with protective devices and warning signs.

i. The safety of operators

The machine is totally enclosed with perfect reliable safety door and also equipped with aluminum antislip plate on the principal

surface, which can assure operators' safety to the largest degree.

ii. The safety of the machine

The multiple points detection technique is adopted to ensure the safe running of the positioning system, the clamping system

and the stretching system to the largest degree.

This series is widely used for making PET bottle for drinking water,edible oil, food, daily chemical……ect.
