The bottle filling machine is the most important part of our 5 gallon filling line. It is a rotary filler for bottled water production. It is mainly made of the main transmission unit, filling unit, and the start wheel for bottle loading and unloading. The filling unit of the liquid filling machine consists of the water feeding device, filling buckets, filling valves, and so forth.
Working Principle of the Bottle Filling Machine
This bottled water filling machine makes use of the micro-pressure filling. It uses a water pump to supply water to the filling bucket which should be full during the whole filling process. A pressure sensor is set to the top of the filling bucket. Signals are sent to the transducer via this pressure sensor. Then, the transducer will control the rotation speed of the water pump motor, so as to ensure the constant filling pressure.
Bottles will be fed to the bottle filling machine by the star wheel. Once they arrive at the filling area, they will be lifted up by a roller. The filling valves start to fill the bottles. When the bottles get to the end of the filling area, they will get to the cam lower part along with the roller. Under such condition, the filling valves will automatically shut down. Those filled bottles will be sent out by the star wheels.
Star Wheel AdjustmentThe start wheel is a key component of the bottle filling machine, and functions to load and unload the water bottles. The distance between the star wheel and shaped plate adapts to the filling bucket diameter. The maximum diameter is 3mm. If the star wheels don't work synchronously, you need to loosen the bolts on the middle part of the axle. After you have adjusted the star wheels, screw down the bolts.
