High-Precision Automatic Small Bottle Liquid Filling And Capping Machine
The Automatic Small Bottle Filling and Capping Machine is designed for precise filling and reliable capping of small liquid bottles. It integrates bottle feeding, filling, and capping into one compact system. With servo-driven magnetic gear pump technology, the machine ensures high filling accuracy, stable operation, and easy cleaning, making it ideal for industries such as food, cosmetics, pharmaceuticals, and daily chemicals.
Description
Introduction
This automatic filling and capping machine adopts a rotary indexing system with six working stations driven by a servo motor. Fourteen bottle holders move evenly along the circular chain to complete the filling and capping process efficiently.

Detailed Description:
The machine automatically feeds bottles into the working station. Photoelectric sensors detect the presence of bottles before filling begins, ensuring precise and safe operation. The filling nozzle adopts an insert-type design that moves up and down with a pneumatic cylinder, preventing dripping and improving filling accuracy.
A servo-driven magnetic gear pump is used for liquid metering, achieving a filling accuracy of approximately ±1%. The capping system uses a servo three-claw mechanism with adjustable torque to ensure tight and stable sealing.
The machine is equipped with a vibratory bowl feeder that automatically arranges caps and delivers them to the capping track. All parts in contact with materials are made of high-quality stainless steel and silicone hoses. Quick-release connections allow easy disassembly and cleaning.
For materials that require temperature control, a heating and constant-temperature hopper can be customized.

Machine Details
Intelligent Photoelectric Detection
Equipped with photoelectric sensors that detect bottles and caps. Filling starts only when a bottle is detected, and capping proceeds only when a cap is in place.
Anti-Drip Insert Filling Nozzle
The filling nozzle adopts an insert-type design and moves up and down with a lifting cylinder, effectively preventing dripping and keeping the filling process clean.
Automatic Cap Feeding System
A vibratory bowl feeder automatically arranges caps and transfers them to the capping track, ensuring continuous and efficient cap supply.
Precision Filling System
The servo-driven magnetic gear pump ensures accurate and stable filling with minimal error.
Servo Capping System
The three-claw servo capping head provides adjustable torque for consistent sealing quality.
Food-Grade Materials
All contact parts are made of stainless steel and silicone hoses to ensure hygiene and durability.
Easy Cleaning Structure
Quick-release clamps allow fast disassembly for cleaning and maintenance.
Operation Process
1.Bottles are placed onto the feeding section.
2.Bottles move to the rotary working stations automatically.
3.Photoelectric sensors detect bottles before filling.
4.The filling nozzle inserts into the bottle and performs precise liquid filling.
5.Caps are automatically delivered by the vibratory feeder.
6.The servo three-claw system performs automatic capping.
7.Finished bottles are discharged from the machine.
Common Problem
What bottle sizes can the machine handle?
The machine supports bottle diameters from 15mm to 50mm and heights from 50mm to 250mm. Custom sizes can also be accommodated.
What types of liquids can be filled?
It is suitable for most liquid products, including water-like liquids, oils, cosmetics liquids, and pharmaceutical solutions.
How accurate is the filling system?
The filling accuracy can reach approximately ±1% thanks to the servo-driven magnetic gear pump.
Is the machine easy to clean?
Yes. The filling system and material-contact parts use quick-release clamps, allowing easy removal and cleaning.
