What is Water Filling Machine?

Classification

• Classification by Filling Principle
  • Atmospheric Pressure Filling Machine: Filling is carried out by the self - weight of the liquid under atmospheric pressure. It can be divided into two types: timing filling and constant - volume filling. It is suitable for filling low - viscosity liquids without gas, such as milk and wine.
  • Pressure Filling Machine: Filling is carried out under pressure higher than atmospheric pressure. It can be divided into isobaric filling and differential pressure filling. In isobaric filling, the pressure in the liquid storage tank is equal to the pressure in the bottle, and the liquid flows into the bottle by its own weight. In differential pressure filling, the pressure in the liquid storage tank is higher than the pressure in the bottle, and the liquid flows into the bottle due to the pressure difference. High - speed production lines often adopt this method. It is suitable for filling liquids containing gas, such as beer, soda water, and champagne.
  • Vacuum Filling Machine: Filling is carried out under pressure lower than atmospheric pressure in the bottle. It has a simple structure, high efficiency, and a wide range of adaptability to the viscosity of materials. It can be used for filling oils, syrups, fruit wines, etc.
• Classification by Filling Operation Type
  • Fully Automatic Liquid Filling Machine: It has a high degree of automation. From the entry of bottles to the completion of filling, capping, and packaging, the whole process does not require manual intervention. It usually includes a filling system, a capping system, a conveying system, a cleaning system, a detection system, and a control system, and can operate at a high speed, which is suitable for large - scale production lines.
  • Semi - automatic Liquid Filling Machine: It adopts a single - head plunger - type quantitative filling device, and the quantitative supply of materials is achieved by adjusting the movement distance of the plunger. Some operations, such as loading and unloading, need to be assisted by manual labor.

Structural Composition

• Barrel - type Water Filling Machine
  • Bottle Washing Part: It includes a bottle washing transmission mechanism, bottle holders, a potion bottle washing water pump, a potion water tank, a pure water bottle washing water pump, a transmission chain, etc. The water buckets are disinfected and rinsed through multiple stations.
  • Filling Part: It consists of a filling cylinder, a filling valve, a cap sorting motor and cap - putting device, a capping cylinder and capping device, etc., responsible for filling water into the barrels and completing the operations of putting on and pressing the caps.
  • Electrical Part: It is composed of a micro - computer programmer and an electrical control box to achieve the automatic control of the equipment.
  • Pneumatic Part: It is composed of cylinders, pneumatic solenoid valves, and a pneumatic electrical control box, providing power for the operation of the equipment.
• Small - bottle Water Filling Machine
  • Filling System: The core component is responsible for accurately filling water into small bottles. Usually, constant - pressure or vacuum filling methods are used.
  • Capping System: Automatically aligns the bottle caps with the bottle mouths and tightens them to ensure tightness and prevent secondary pollution.
  • Conveying System: It is used to transport empty bottles into the equipment and send out the filled bottles, including components such as conveyor belts and chains.
  • Cleaning System: It uses pure water or disinfectant to rinse the inside of the bottles to ensure that the bottles are clean and sterile.
  • Detection System: It detects the filling volume, whether the bottle caps are properly sealed, and the integrity of the bottle body, etc., to ensure product quality.
  • Control System: It uses a controller such as a PLC to accurately control all aspects of the equipment and achieve automatic operation.

Working Principle

• Barrel - type Water Filling Machine
  • Bottle Washing: First, the water buckets enter the bottle - washing station. Generally, they are washed and disinfected with a chlorine dioxide solution and then rinsed with pure water for multiple times. Finally, the residual water in the buckets is dried.
  • Filling: The dried buckets are sent to the barrel - supporting mechanism through the chain conveying mechanism. After being uprighted, the filling valve is pressed down to start filling. The filling time is adjusted according to the flow rate of the filling pump.
  • Cap - putting and Capping: After filling, the filled barrels are sent to the cap - sorting machine for cap - putting through the out - barrel transmission mechanism, and then sent to the capping mechanism. The capping cylinder presses the bottle caps tightly to complete a washing - filling cycle.
• Small - bottle Water Filling Machine
  • Bottle Feeding: Empty bottles are automatically sent to the feeding area of the equipment through the conveyor belt, and the equipment automatically distributes the placement positions of the empty bottles.
  • Rinsing: The inside of the bottles is rinsed to remove impurities and bacteria, ensuring that the bottles are clean.
  • Filling: Drinking water or mineral water is injected into the bottles according to the set filling volume. Precise metering technology is used to ensure filling accuracy.
  • Capping: Automatically aligns the bottle caps with the bottle mouths and tightens them to ensure the tightness of the bottles.
  • Detection: Detects the filling volume, the tightness of the bottle caps, the integrity of the bottle body, etc., and rejects unqualified products.
  • Bottle Discharging: The bottles that have completed filling and detection are transported out via the discharging conveyor belt and enter the subsequent labeling and packaging processes.

Application Scenarios

• Mineral Water and Purified Water Factories: Produce small - bottled or barreled mineral water and purified water on a large scale to meet the daily consumption needs of the market.
• Beverage Manufacturers: In addition to being used for filling purified water and mineral water, it can also be used for filling non - carbonated beverages such as fruit juices and tea beverages. Some models can also handle the filling of carbonated beverages.
• Catering and Retail Industries: Provide bottled water for convenience stores, supermarkets, restaurants, etc., to meet the immediate drinking needs of consumers during dining and shopping.
