35-50 pcs/min Liquid Filling Machine for Cosmetic Bottles

Filling Machine for Cosmetic Bottles Product Introduction 

The 35–50 pcs/min liquid filling machine for cosmetic bottles is engineered for high-speed, precise, and hygienic filling of various cosmetic liquids. Utilizing a dual-track system, the machine can continuously fill multiple bottles simultaneously. The system integrates PLC control with a touchscreen interface, allowing adjustment of filling speed, volume, and operation parameters. Adjustable bottle holders and filling nozzles accommodate different bottle sizes. This machine is perfect for hand soap, lotion, shampoo, liquid detergent production lines, OEM cosmetic manufacturing, and automated small to medium production lines.

Working Principle：

The dual-track liquid filling machine operates by continuously feeding bottles along two parallel tracks. Liquids are drawn and dispensed through hygienic pumps controlled by a PLC system, which regulates volume, speed, and timing. Sensors detect bottle presence to prevent overflow or missed filling. The adjustable nozzles and holders accommodate different bottle shapes and sizes, while the dual-track configuration allows simultaneous filling, maximizing throughput and maintaining precision. The system is designed for easy cleaning and minimal cross-contamination.
