The automatic packaging line for liquid filling and screwing is a fully automated packaging solution that integrates filling, screwing, labeling, coding, and inspection, specifically designed for the large-scale production of various liquid products.

This production line adopts a modular design concept, allowing flexible configuration according to different product characteristics and production capacity requirements. It achieves full-process automation from empty bottle feeding to finished product palletizing, significantly improving production efficiency and packaging quality.

Core components

Automatic bottle loading system: Utilizing conveyor belts or robots for automatic bottle loading, precise positioning ensures that the bottles enter the filling station smoothly.

High-precision filling system: Equipped with servo-driven filling valves, it achieves a filling accuracy of ±0.5%, adapts to liquids of different viscosities, and eliminates dripping and leakage.

Automatic cap screwing system: Automatically completes the orientation, placement, and tightening of caps, with adjustable torque to ensure consistent sealing.

Labeling and coding system: It achieves automatic labeling and precise printing of production date, batch number, and other information.

Online detection system: Integrating functions such as liquid level detection, cap skew detection, and label detection to ensure product quality.

Back-end packaging system: It completes subsequent processes such as cartoning, packing, and palletizing, achieving full automation across the entire line.

Core advantages of equipment

Efficient and stable production: The entire production line can operate at speeds of 80-300 bottles per minute, with 24-hour continuous operation and a failure rate of less than 0.5%.

Precision filling control: Utilizing a flow meter or weight feedback system, the filling accuracy reaches up to 99.5%, reducing material waste.

Rapid production changeover capability: Modular design combined with quick-change structure allows for bottle type and specification switching in just 15-30 minutes.

Intelligent control system: Equipped with PLC and touch screen human-machine interface, it features intuitive and easy parameter setting, as well as a comprehensive fault self-diagnosis function.

Hygienic and safe design: The parts that come into contact with liquids are made of SUS304/316 stainless steel, which complies with GMP/FDA standards and supports CIP/SIP cleaning.

Scope of application industries

Food and beverage industry: packaging of liquid foods such as juice, milk, soy sauce, vinegar, edible oil, alcohol, and beverages.

Daily chemical industry: filling of daily chemical products such as shampoo, body wash, skin care products, detergent, disinfectant, etc.

Pharmaceutical industry: aseptic filling of pharmaceutical products such as oral solutions, injections, liquid medicine, and disinfectant alcohol.

Chemical industry: Packaging of chemical liquids such as lubricants, coatings, adhesives, and pesticides.

Detailed explanation of workflow

Empty bottle feeding → bottle body cleaning → precise filling → automatic cap screwing → tight sealing → labeling and coding → quality inspection → finished product output
