Small automatic liquid filling machine working principle

This 4 head liquid filler uses a piston/pump/overflow filling system, controlled by PLC and touch screen. Bottles are positioned automatically, and each of the 4 nozzles dispenses an accurate volume of liquid, ensuring consistent filling speed and precision.

Bottle feeding stage 

• The bottles or containers are transported to the filling head through a conveyor belt or screw feeding system. A sensor or photoelectric detector confirms whether the bottles are positioned correctly to avoid leakage or overflow during filling.
• Thanks to our advanced design, the filling error of our bottle filling machine is about ±0.1, ensuring high precision and consistency.

 Positioning and cleaning (customizable option)

• For industries such as food and pharmaceuticals, bottles may require an additional cleaning process before filling.
• As a professional filling machine manufacturer, we provide customizable bottle-cleaning modules to ensure containers remain sterile and free from contamination before filling.

Filling process 

• Depending on the liquid’s characteristics, we offer multiple filling methods:

• Gravity filler – Suitable for low-viscosity liquids, using natural liquid flow.

• Pressure filler – Suitable for viscous or carbonated products, using a pressure pump.

• Vacuum filler – Ideal for volatile or foaming liquids, where a vacuum draws the liquid into the bottle.

• Metering filler – For high-precision applications, using flow meters or metering pumps.

Once the filling valve opens, the liquid flows from the reservoir into the bottles. The volume is precisely controlled by time, weight sensor, or flow meter, ensuring accuracy in every fill.

Stop filling & capping stage (customizable option)

After reaching the pre-set volume, the filling valve automatically closes to prevent overflow.

The filled bottles are quickly moved to the capping section, where different cap types—screw caps, press caps, snap caps, etc.—are sealed securely. We integrate automatic capping machines or torque cappers to guarantee tight, reliable sealing for each bottle.
