Bottle Washing Machine

Bottle washing machine consists of bottle washing clamp, upper turntable, guide rail, water distributer, protective cover, water spray device, water collecting tray. All parts in contact with the liquid is SS304 or SS316. The bottle wash clamp is integrally molded, and lubricating parts of the active part is from Igus. It is more durable than ordinary bottle washing clamp for 5 years.

Filling Machine

Filling machine consists of filling tank, filling valve, control ring, lifting device, etc. The liquid contact part is SS304 or SS316, and the thickness of the filling tank’s bottom plate is up to 30mm. The filling valve is Germany style and was manufactured by China’s top filling valve company.

Capping Machine

Capping machine consists of bearings, lifting worm gear components, transmission gears, capping heads, cams, machine reducers, etc. It is magnets torque, and the torque is adjustable. This capping machine is stable, and it has low cap scrap rate. When the cap type changes, only need to change capping head and seat. It is easy to adjust machine when change cap type.

Filling Process of Water Filling Machine

Air conveyor/conveyor sends bottles to star wheel. Star wheel sends bottles to bottle washing machine. There are bottle clamps on washing machine. Bottle clamps clamp the bottle neck and flips 180° along the guide rail to let the bottle mouth down. In the specific area of the bottle washing machine, washing nozzle sprays water into bottles to rinse the inner wall of bottles.  

After washing and draining, bottles flip 180° along the guide rail to let bottle mouth up. Star wheel sends washed bottles from washing machine to filling machine. The lifting device raises bottles under the action of the lifting cam. Bottles contact and press the filling valve, and then the filling valve spring opens the filling valve and starts filling. Filling stops automatically when the liquid level reaches the vent.  The lifting device lowers to let bottle leave filling valve.

Star wheel sends bottles to capping machine. The stop knife on the capping machine locks the bottle neck, keeping the bottle upright and preventing rotation. The capping head keeps the revolution and rotation on the capping machine, and realizes the action of cap grabbing, cap covering, cap screwing and cap releasing under the action of the cam. Star wheel sends bottles from the capping machine to the bottle conveyor. Bottle conveyor sends bottles to next machine.

Q1: Where Is The Water From?

Bottled water factories always get raw water from natural springs, boreholes, and tap water. Nowadays, seawater is also a big source because of the use of desalination technology.

natural springs

tap water

boreholes

Desalinated seawater

Q2: How Does Carbonated Beverage Filling Machine Keep Constant Liquid Level in The Bottle?

The length of the vent decides the height of the liquid level. Keep the same vent length, bottle shape, and size, the liquid level is always at the same height.

The filling valve bottle mouth, Filling starts. Air in the bottle returns to the filling tank through the vent inner hole. When the liquid level in the bottle reaches the vent, the air circuit is cut off and stops filling the water. We can adjust the liquid level by changing the length of the vent.

Q3: How to Fill Multiple Bottles at Once?

Bottles with the same neck size, and the bottle diameter difference isn’t more than 5mm, one set of filling machine can fill them all.

If the bottle has the same neck size, but the bottle diameter difference is more than 5mm, we will need the bottle change parts. Each set of bottle change parts is customized according to the bottle size. The bottle change parts include the bottle star wheel and bottle fixing parts.

If the bottle neck size is different, we will need the change parts mentioned earlier. Moreover, all parts in contact with the bottleneck. For example, the bottle neck holder, clamp, the capping head, and the seat.

Q4: Can A Water-Filling Machine Fill Juice, Soda, And Other Drinks?

No. Because the filling principles of different liquids differ. For more information about different filling machines, please click

Q5: Can Plastic, Glass, And Aluminum Bottles Be Filled On One Machine?

No. Because different bottle and cap materials require different filling and capping mechanisms.

For instance, we fill plastic bottles with a bottleneck clamping system and glass bottles with a bottle bottom supporting system.

To customize your machine, in addition to the bottle material and size, you also need to tell us the cap material, such as plastic cap, crown cap, aluminum cap (short aluminum cap or high aluminum cap), twist-off caps, etc.

Q6: What Is The Speed Of The Bottled Water Filling Machine?

Speed range of small-bottle water filling machine: 1000-20000 bottles per hour based on 500ML bottles.

For more details about the components of the 5gallon water filling machine, please check

Filling Process of Water Filling Machine

The internal washing machine can be independent or combined with a filling machine and a capping unit. The conveyor delivers the cleaned empty barrel to the automatic barrel loading and washing process. After the barrel-enter counter detects the quantitative empty barrel, the front barrel cylinder blocks the empty barrels on the conveyor belt, then the barrel-pushing cylinder pushes the empty barrels into the barrel-loading rack, which rises to make the barrels recumbent (the barrel mouth is aligned with the barrel support device), the barrel-enter cylinder then pushes the empty barrels into the barrel support device and resets. The empty barrel moves one station with the spindle motor chain, and in an inverted manner, then the barrel support device sprays water to flush the inside of the barrel mouth and barrel body. The flushing procedure mainly consists of hot alkaline water flushing, disinfectant flushing, circulating water flushing, and purified water/ozone water flushing. The washed barrels arrive at the barrel-out mechanism in a horizontal state.
The cylinder dials the washed barrels to the barrel turnover rack and turns it 90 degrees to make the barrels vertical with the filling conveyor. Once the barrels are in place, the barrel-pushing cylinder pushes the barrels out and resets.

The barrel-pushing mechanism pushes the washed barrels to the filling position, the drinking water enters the water distributors from the water tank via the water pump, and the water distributors distribute it to each filling valve. The filling valve begins to fill with water once the barrel-clamping device has located its center. After filling the water to a certain level, the filling stops, and the empty barrel pushes the full barrel into the conveyor belt to begin the subsequent round of filling.

The caps enter into the caps unscrambler by the caps elevator, after the caps-unscrambler arranges the caps, and delivers the caps into the caps sterilizing tunnel for caps washing. After washing and drying the caps, caps will enter into the caps-sleeving area by the caps tunnel, sleeving caps onto the barrel and pressing. After capping, the barrel water will go through the packing procedure by the conveyor.
