(1) Hopper and elevating system

A certain amount of preforms will be stored in hopper to guarantee the continuous of producing. The preforms will be elevated to the lining device by the belt of hopper and then sent to the oven along the filling rail to be further produced.

Description of equipment’s performance:

Once preforms are loaded into the hopper, they are supervised by the computer. The number of the loading preforms can be automatically adjusted according to the production speed;

The output speed can be freely adjusted according to different preforms to make the number of loading preforms match up with the production speed;

The design of rotary plastic transferring belt ensures preforms avoiding damage and contamination during the transferring;

After being lined, preforms pass the guiding wheel to the dust moving device, then to preform seats, and then go into the oven to be heated. Preforms are heated by seven to ten layers lamps in the oven, every layer lamps can heat separately. The heating circulation of the fan in the bottom of the oven make the average temperature of the inside oven.

(2) Oven

In the oven the preforms move forward and rotate themselves to make every part of the bottle have the same temperature. After heating, the preforms have elastomeric property, so the preforms can be stretched biaxial. For the soft drinking bottles the range of temperature is 90~100℃, while for hot filling bottles the range is 110~120℃. The heat of the oven is controlled by the quantity of the working lamps, the whole setting temperature and the power of the oven.

The structure of oven

The heating control of the infrared lamps adopts the closed loop control. After setting the temperatures of oven and preforms, the computer will automatically monitor and ensure the fluctuate of temperature within the certain value to avoid effecting production because of the different temperature between day and night;

After being heated, preform will be checked by the automatic infrared inspector, its temperature will shown on the computer, which make every preform has the same temperature and further ensure the stability of the blowing technique and high finished goods rate;

When the equipment breaks down, the special designed quickly air cooling device ensures prefroms still staying in the oven be cooled quickly, thus these preforms can be used again;

The special designed preform ejecting device can eject the unqualified performs.

(3) Mainframe of blowing machine

Full Automatic Blow Molding Machine PET Bottle Rotary

After being heated in the oven, the preform will be transferred into the mold by transfer arm. The preform will be sealed by sealing seat, stretched by stretching seat and blown by low pressure air and high pressure air (hot filling bottle will blown by cooling air). According to different technical requirements, the mold will be cooled by cooling water if blows cold filling bottle, the mold will be heated by hot oil if blows hot filling bottle. The whole production process will be monitored by computer.

Bottle’s checkup and output

After being blown, bottle will be transferred out of mold to output rail which can be connected with the air conveyor of the filling production line. Or bottle will be directly transferred on the conveyer belt to the bottle storehouse.

Working theory of bottle blowing machine

The main cam will rotate in high speed. The rotary angle will be tested by the coder on the top of the equipment and the sensor installed on the main cam. Then the information will be sent back to the computer which will send message to the solenoid valve according to the program settled by the operator. The certain action will be carried out to blow in the certain time to finish the double oriented method blowing technique during the rotary of the machine and the conforming bottles will be produced.

(4) Drive and synchronization system

Drive and synchronization system

Setting the speed on the control panel → PCC(programmable control system) → transducer → main electric motor → gear box → belt wheel → toothed belt → speed cam and preform transfer belt wheel → oven belt wheel and bottle transfer belt wheel → preform filling wheel and bottle produced cam

(5) Special mold frame system

Full Automatic Blow Molding Machine PET Bottle Rotary

The special designed mold frame system ensures the possibility of quick and accurate changing mold;

Mold frame with air pressure balance device makes the minimum break line when blowing bottles, which guarantee the quality of the bottles;

The special neck sealing design reduces the pressure between preform neck and sealing to the minimum, thus the neck of preform couldn’t be damaged.

(6) Twice stretching system

The equipment has the special designed twice blowing system (equipment for hot filling bottles has three times blowing system) ------ preblowing, blowing with high pressure to finally make bottle. The blowing pressure and time of the second blowing can be adjusted. The system can guarantee the quality of finished bottle, so some bottles with complicated shapes can be blown;

The system has the special designed pressure over loading and loss protection devices which can prevent the pneumatic parts from damaging;

The system has the special designed stretching rail which guarantees every bottle can be stretched with the same speed and power during the stretching process.

(7) Transfer arm system

The transfer of preforms and bottles are finished by transfer arm, which prevent prefroms and bottles from contamination;

The stainless steel transfer arm is processed precision, softly contacts with prefrom or bottle, which can avoid the scratching of the neck;

The transfer arm has the twisting force over loading protection device which prevent the equipment from damaging when it breaks down

(8) Safe and reliable mechanical transmission

Full Automatic Blow Molding Machine PET Bottle Rotary

All the important parts of the transmission come from the famous brands in Europe and American, so equipment has the reliable quality and long service life,The connection of the key transmission has the soft protection system;

The special designed mechanical protection and automatically replace system: prefrom entering device, oven, transfer arm, rotating blower, main motor, all the above have the twisting force over loading protection system. Even though equipment breaks down, it won’t be damaged;

Torsion clutch of equipment adopts American brand which can easily adjust the grades, with automatic overloading reset functions. After eliminating resistance, the transmission system will automatically rotate by itself, all linked parts will accurately reset to the original position, without the adjusting of the operator. So all the system is convenient and quick;

The transmission of main motor adopts German SEW Company’s frequency conversion motor, positive speed gearbox and transducer, which have characteristics of flexible non-class starter, non-class adjustment, safety and stability;

Accurate connection between toothed belt and toothed belt wheel guarantees the accurate and safe running of every transmission part.

(9) SIEMENS PLC controlling system

The controlling system of automatic blowing machine is made up with SIMATIC HMI (man-machine interface), Siemens industry controlling system (PLC system) and related controlling, checking and executing parts. The turn-on, turn-off and heating adjustment of equipment can be done by the man-machine interface automatically.

SIMATIC HMI(man-machine interface)operating panel contains 36 programme functional keys(28 of them with LED). Bottle blowing machine can be controlled by pressing the keys on the operational panel or by clicking the mouse(USB interface is under the bottom of the panel).

4. Advantages of Sunswell bottle blowing machine

Humanization man-machine interface

It’s easy to learn the operation of man-machine interface, because there will be the breakdown position and explanation. Every solenoid valve and cylinder can be checked to separately control every mold to blow bottles.

Recycle the high blow air, so no need to build low pressure air station.

With perform block inspect device, when any perform blocked, it will reject automatically and recovery automatically.

Less time mold change time, can improve the production.
