Working principle

Step 1. Automatic Bottle Feeding

Empty PET bottles are transferred into the rinsing system through the air conveyor automatically.

Step 2. Bottle Washing Process

High-pressure stainless steel rinsing nozzles clean the internal bottle surface to remove dust and impurities.

Step 3. Automatic Bottle Transfer

Clean bottles are transferred directly into the filling section through synchronized mechanical grippers.

Step 4. Precision Water Filling

The filling valves inject purified water or mineral water into bottles with controlled liquid levels.

Step 5. Cap Feeding and Placement

Bottle caps are automatically sorted and delivered into the capping unit through the cap elevator.

Step 6. Automatic Bottle Capping

The capping heads tighten bottle caps securely to ensure leak-proof packaging quality.

Step 7. Finished Bottle Output

Completed bottles are discharged to the conveyor system for labeling, packaging, and palletizing.
