Product Overview
The entire working procedure is controlled via human-machine interface, realizing fully automatic operation including automatic preform loading, automatic bottle blowing and automatic bottle discharging.
All pneumatic cylinders are fitted with magnetic induction switches. The PLC control system monitors every cylinder action in real time: the next action will only start when the previous stroke reaches the designated position. If any stroke fails to reach position, the system will trigger automatic protection, stop subsequent actions, send out an alarm and display the exact fault location on the PLC screen.
With advanced servo drive system and patented variable center distance design, it delivers outstanding production efficiency and energy-saving performance, and produces bottles with uniform wall thickness and flawless mold lines.
Equipment Features
- High production efficiency The output for water bottles reaches 1800 bottles per hour per cavity. The heating cycle and blowing cycle run independently, and movements of mold clamping, mouth sealing and bottom mold lifting are fully synchronized, ensuring high-speed stable continuous production.
- Remarkable energy saving performance The application of electric servo system significantly reduces low-pressure air consumption. Equipped with patented variable center distance system, the heating oven length is shortened by over 55% compared with fixed center distance systems, delivering outstanding energy saving effect.
- Premium bottle forming quality The high-efficiency mold clamping system ensures perfect flawless mold lines on bottle bodies. Precise bidirectional axial uniform heating guarantees even wall thickness of finished bottles, realizing lightweight bottle production with stable quality.
- Intelligent fully automatic control Human-machine interface enables intuitive operation of the whole production process. All action cylinders are equipped with magnetic induction switches, and the PLC system performs real-time stroke detection. It features automatic fault alarm and fault location display, ensuring safe and reliable operation with low failure rate.
- Precise synchronous operation Mold clamping, mouth sealing and bottom mold lifting/lowering movements run in full synchronization. The dual independent cycles of heating and blowing cooperate smoothly, with accurate operation rhythm and stable long-term running performance.
Working Principle
PET preforms are automatically fed into the machine by the preform loader. They first enter the heating oven, where bidirectional axial uniform heating is applied to bring preforms to the optimal forming temperature.
Heated preforms are then transferred to the blowing mold station. The mold clamping, mouth sealing and bottom mold mechanisms move into position synchronously. High-pressure compressed air is injected into the preform to blow it into the shape of the mold cavity, completing bottle forming.
After forming, the finished bottles are automatically demolded and discharged from the machine. The heating cycle and blowing cycle run independently and cooperate with each other, which greatly improves production efficiency. The servo drive system ensures accurate and consistent movement of each mechanism, guaranteeing stable product quality batch after batch.
