Production Process for Bottle Water Packaging Machine

Blow molding → Air conveying → Rinsing, filling, and capping → Inspection → OPP labeling → Bottle conveying → Drying → Coding → PE film heat-shrink packaging → Finished product

Equipment in Liquid Filling Line

Filling Unit

This unit integrates rinsing, filling, and capping functions. It is equipped with 18 rinsing positions, 18 filling valves, and 6 capping heads. The production capacity is 6,000 bottles per hour for 500ml bottles and 3,000 bottles per hour for 1,500ml bottles; actual output depends on factors such as the product and bottle size. It utilizes a “neck-hanging” conveyor design to ensure smooth operation and features automatic liquid level control and variable frequency speed regulation.

Air Conveyor

The air-conveying system suspends PET bottles by gripping their neck rings and transports them to the filling unit using a controlled airflow. The airflow rate is approximately 1,200 m³/h. By conveying the bottles via their neck rings, the system avoids the issue of empty bottles tipping over.

Light Checker

After the filling and capping processes, the bottles pass through the visual inspection station. This station features an illuminated inspection zone, enabling operators to identify visible foreign matter, liquid anomalies, sealing issues, or bottle defects.

Bottle Drying Machine

Drying is a crucial stage in the liquid filling line. The equipment utilizes angled, narrow-slot air nozzles to direct airflow onto the bottle surface to remove residual moisture. It features a 304 stainless steel body, a blower, and an automatic air filter.

Laser Marking Machine

It can print production dates, batch numbers, traceability codes, and other information on the bottle body, cap, or label. The marking machine uses a QR code scanning system, a built-in control screen, photoelectric product detection, and an air-cooling system. Utilizing laser coding technology, it operates without the need for consumables such as ink.

OPP Hot-Melt Glue Labeling Machine

An infeed screw spaces the bottles, a star wheel positions them, and the machine rotates them during labeling. After cutting each label, a vacuum drum transfers it to the bottle body, while hot-melt adhesive secures the label at its leading and trailing edges.

Shrink Wrapping Machine

At the end of the filling line, PE film is used for wrapping. The equipment automatically handles bottle infeed, grouping, film feeding and cutting, heat shrinking, cooling, and finished product discharge. The shrink tunnel utilizes hot-air circulation and a multi-layer thermal insulation design.

Considerations Before Purchasing an Automatic Liquid Filling Line

  • What is the available floor space?
  • What are the bottle and cap specifications?
  • What packaging configuration is used?
  • What is the target output?
  • What is the local supply voltage?
  • What is the water quality?

This production line is primarily used for filling purified water and mineral water. Depending on your specific product and hygiene requirements, it can also be configured for the production of other non-carbonated beverages. Factors determining production output include bottle capacity, label dimensions, packaging format, and staffing levels.
