Blowing - Filling - Capping Combi-block System

Filling system

- The liquid level is controlled at the diameter line of bottle shoulder: error upper limit +1.5mm, lower limit -1.5mm; The number of filling heads is proportionally configured with the number of blowing stations and cappers to facilitate the abnormal tracing, the filler is equipped with hundred-level laminar cover. The position for the nitrogen dosing system is reserved before the capping.

Washing system

- The rotary disk is fully made of SUS304 stainless steel.
- Using imported special efficient spray nozzle, the washing water will be sprayed in a particular angle, can wash any part of the inner wall, rinse with water thoroughly and save flush bottle.
- Bottle clamp and lifting mechanism of sliding sleeve adopts Germany Igus corrosion resistant bearing without maintenance.
- Washing part moves by a frame in the transmission system through the gear transmission.

Capping system

- Transition wheel: steel wheel is used to lift the bottle neck, not required for equipment height adjustment for bottle changeover;
- Bottle outlet wheel: bottom transfer method is adopted, the bottom supporting plate is a spiral descending curve, not required for equipment and conveyor height adjustment for changeover.
- Magnetic constant torque capper, the capping effect is stable and reliable, the rate of defective capping≤0.2%;
- The cap falling guide is equipped with a mechanism to prevent the reverse cap inlet and reverse cap outlet, a group of photoelectric switches are installed at the same time. When there is no cap on the cap falling guide, the machine will automatically stop running which effectively avoid no-cap bottle.

- Capping effect is stable and reliable, Defective rate ≤0.2%

Washing system

- Heated preform will be transferred to the blowing station by specialized manipulator, which is moving along the cam curve. Preform will be firstly stretched and pre – blew in the mold, thereafter, blew to the bottle by second high pressure compressed air blowing. The bottle afterwards will be taken out from the blowing mold by manipulator (moving) along the cam curve. The high pressure valve sets are made of high-quality products to ensure the stability and reliability of the blow molding process. Independently developed integrated high pressure valve sets and mechanical seals, with smaller dead zone gas space than similar products, better reduce the consumption of high pressure compressed air. The back-pressure structure for the high pressure inside the sealing cylinder uses the high pressure gas in the blowing bottle to directly realize the sealing of the blowing nozzle, which can reduce the impact of the blowing nozzle on the mold and reduce the consumption of the low pressure compressed air. Convenient and accurate mold installation structure, combined with the use of the cooling water quick-plug connector with one-way globe valve, makes the mold replacement more convenient and fast. It only takes two hours to replace the whole mold.
- The new generation of rotary blow molding machine adopts a number of technical and patented functions, with the advantages of stability, reliability, high efficiency, energy saving and environmental protection.
