20-30 Bottles/min Liquid Filling Machine for Dropper Bottles Line

Liquid Filling Machine Product Introduction

The liquid filling machine is a compact desktop system designed for automatic filling and capping of small volume liquid products. It supports low viscosity liquids such as essential oils, perfumes, and eye drops, and can be equipped with magnetic or peristaltic pumps depending on application needs. The machine integrates bottle sorting, filling, cap feeding, and capping into a single workflow, improving efficiency and reducing manual labor. It addresses challenges such as inconsistent filling, low productivity, and complex operation. Suitable for cosmetic, pharmaceutical, and personal care manufacturers, it provides a flexible and space saving solution for small scale production.

Working principle

The liquid filling machine operates using a turntable system that automatically feeds bottles into different stations. Bottles are first positioned by the feeding device and detected by electric sensors. The filling system then dispenses liquid into each bottle using either a magnetic pump or peristaltic pump. After filling, the cap feeder places caps onto the bottles, and the capping head secures them. The coordinated system ensures accurate filling, proper sealing, and continuous automated production.
