Product Overview

In the cosmetic industry, accurate liquid filling is essential for maintaining product quality, reducing material waste and ensuring consistent consumer experience. Traditional manual filling methods often cause problems such as uneven filling volume, low production speed and unstable product quality.

The Automatic Cosmetic Liquid Filling Machine for Dropper Bottles provides an efficient automation solution for small bottle liquid filling applications. Through precise bottle positioning and advanced metering technology, the machine ensures each bottle receives the correct filling volume with high repeatability.

The equipment is specially designed for cosmetic liquid products with strict filling requirements, including essential oils, serums, facial care products and other premium skincare products. Its compact structure and flexible configuration make it suitable for cosmetic factories, OEM manufacturers and beauty product production lines.

Working Principle

1. Bottle Feeding
Empty dropper bottles are automatically transported into the filling area through the conveyor system.

2. Bottle Positioning
The positioning mechanism accurately aligns each bottle under the filling nozzle.

3. Liquid Filling
The 316 magnetic pump transfers cosmetic liquid into bottles according to preset filling parameters.

4. Filling Volume Control
The control system adjusts filling volume to maintain consistent dosage accuracy.

5. Bottle Transfer
After filling, bottles are automatically moved to the next production process, such as capping or labeling.

6. Production Monitoring
The PLC control system monitors machine operation and allows operators to adjust production parameters easily.

Process Flow:
Bottle Feeding → Bottle Positioning → Precision Filling → Volume Control → Bottle Output → Next Packaging Process
