1–5L Automatic Filling and Capping Line | Efficient Small-Volume Liquid Packaging

1. Working Principle:
To fill 2L square cans, the empty can is manually placed onto the empty can platform. The can is automatically fed and conveyed to the filling station. Four automatic filling heads are used, followed by automatic capping and capping. The system then moves to the finished product packaging platform.

2. Technical Specifications:
2.1. Features an original, fully explosion-proof touchscreen interface, automatic discharge speed adjustment, automatic discharge accuracy calibration, triple protection for emergency stop, power failure, and can transfer, stores hundreds of packaging specifications, automatically alarms for out-of-tolerance conditions, and is equipped with explosion-proof devices.
2.2. Available for 0.5-5L square cans. The touchscreen automatically adapts to the size of the can, eliminating the need for manual adjustment of mechanical components (optional).
2.3. The packaging equipment can be directly connected to production equipment for operation.
2.4. Fully automatic continuous packaging with fully automated cap placement, capping, and weight checking greatly improves work efficiency and reduces worker workload.
2.5. Optional labeling and palletizing systems are available. See the diagram below for specific dimensions.

1–5L automatic filling and capping line is a fully automated system designed for precise filling, capping, and labeling of small containers ranging from 1 to 5 liters. Ideal for paints, chemicals, adhesives, lubricants, and liquid food products, this line streamlines packaging operations, improves accuracy, and enhances production efficiency for small to medium-sized containers.

Key Features of a 1–5L Automatic Filling and Capping Line

• High-Precision Filling – Volumetric or weight-based filling ensures accurate dosing for every container.

• Automated Capping – Secure and consistent capping reduces spillage and ensures product integrity.

• Labeling Integration – Optional labeling stations provide consistent branding and product identification.

• Compact & Space-Saving Design – Suitable for small- to medium-scale production facilities.
