How the Pressure Overflow liquid Filling Machine works?

Equipped with 16 filling nozzles, this efficient pressure overflow liquid filling machine can easily adjust to fill bottles of various sizes, from 500ml to 5000ml. Its design ensures precise liquid level for each filling, ensuring consistency in bottle filling.

Feeding bottlings on the conveyor and fix the filling postion.Firstly, place the empty bottle on the conveyor belt, which will transport the bottle to the designated filling position and secure it in place. Next, the conveyor stops running and the equipment automatically clamps the bottleneck to ensure that the bottles remain stable during the filling process. At this point, 16 filling nozzles will be immersed into the bottle one by one, starting the filling process.

Conveyor stops ,clamp the bottles neck, nozzles diving into bottles.During the filling process, the variable speed pump is activated to precisely fill the liquid into the bottle. When the liquid level of the bottle reaches the set height, excess liquid will be returned to the supply tank through the overflow pipeline, ensuring that the liquid level of each bottle is completely consistent.

Finally, after the filling is completed, the nozzle will automatically rise from the bottle, the clamping device will be released, and the conveyor belt will restart to drive the already filled bottles away from the filling position and prepare for the next batch of bottle filling work. In this way, the entire process repeats itself in a loop, with high efficiency and precision.
