1.5L Pet Stretch Blow Moulding Machine For 38mm Neck Liquid Milk Drink Bottle

PET Blow Moulding Machine for 38mm Neck Liquid Milk Drinks Bottle , Energy Drinks Bottle

The application of the full closed-loop voltage regulator in preform heating system:

The temperature of the heating ovens are controlled by the full closed-loop voltage regulator (with feedback) which

independently developed by RiBo company. The controller detects and adjusts the output voltage (set value) at the scanning

frequency of 218 times per second, so as to achieve the effect of evenly voltage output and solve the problem of unstable

heating effect caused by the heat fluctuation of heating element (lamps) due to the voltage fluctuation of the power supply. In

addition, the closed-loop control system interacts and cooperates with the original heating ovens’ constant temperature control

system, greatly improving the heating temperature fluctuation caused by environmental temperature change. By application of

the above technology in the bottle blowing machine, the heating uniformity and stability of each preform tend to be completely

consistent, which finally ensures the stability and uniformity of the bottle blowing effect of each cavity. This closed-loop unit has

further improved the overall performance of the bottle blowing equipment.

The machine is equipped with the preform temperature detection at the end of the last heating oven, if the preform temperature

does not reach the blowing temperature, the preforms going into the blow mould but no blowing, saving the air.

Performance and Advantages

1. The man-machine interface is easy to operate. Everything is computerized, including temperature adjustment and preform

distribution.

2. Independent movable operation pannel, make the operation more convenient and flexible.

3. Preform unscrambling, loading, bottle handling and ordering are all operated by stainless steel manipulator automatically

without a second contamination.

4. During the process of the automatic embryo preform feeding system, each preform channel has photoelectric detection,

control the action of the upper motor and the parting cylinder, ensure the uniform distribution of the preform in each embryo

channel, and have the function of alarming the material shortage.

5. The circulating chilling water system as well as the fan with converter controlled can protect the bottle neck against

deformation when the preform is being heated.

6. The homothermal heater adopts auto reflection and closed loop adjusting system which have the power supplied constantly

in proportion, not affected by the fluctuation of voltage. The conveying chain is short pitched and paratactic, which helps to

realize slow heating and low power consumption. As a result, the preform can be heated evenly and easy to blow.

7. The positioned installation of molds makes it possible to change molds easily within one hour,the operator only need to

stand on the ground can finish this job, no need to stand on the machine frame,the safety for person is much higher.

8. All the critical parts we use for the machines, such as the electrical, pneumatic components, servo motor, etc, are famous

branded parts imported from Japan, USA and Europe,which ensures the stability and long life of our equipments.

9. The high pressure blowing valve is equipped with the device of converting to low pressure air, which can ensure the normal

conversion without low pressure air. Machine is equipped with the high pressure air recovery device, in the process of bottle

blowing production, the high pressure air can be recoveried and used for the cylinders/ pre-blow.
