Functions and Maintenance Methods of Liquid Filling Machines

Functions and Maintenance Methods of Liquid Filling Machines


The manual and automatic switching function: When the machine is in an "automatic" state, the machine will automatically and continuously fill at the set speed. When the machine is in the "manual" state, the operator steps on the pedal to realize the filling, and if he keeps stepping on it, it will become the automatic and continuous filling state.
 
Drip-proof filling system: When filling, the cylinder moves up and down to drive the stuffy head. The material tank and tee are handcuffed, without any special tools, and it is very convenient for loading, unloading and cleaning. Excellent accessories can be selected, and the liquid inlet pipe can be filled several times in the cleaning solution until the cleaning is finished. This series of filling machines are plunger filling machines, which are self-priming. The materials are pumped into the metering cylinder by the piston-driven by the cylinder and then injected into the container by the pneumatic piston through the material pipe. The filling quantity is determined by adjusting the stroke of the cylinder.

Classification of liquid filling machines:
Because of the wide range of liquid filling machinery, there are many kinds of liquid filling machines, and there is corresponding filling equipment according to different classifications. According to the filling principle, liquid filling machines can be divided into normal pressure filling machines, pressure filling machines, vacuum filling machines and automatic quantitative liquid filling machines. According to the type of filling operation, they can be divided into automatic liquid filling machines and semi-automatic liquid filling machines. According to filling types, they can be divided into diluted liquid filling machines, concentrated liquid filling machines and oil filling machines, etc.
 
Atmospheric filling machines
The normal pressure filling machine is filled by the dead weight of liquid under atmospheric pressure. This kind of filling machine is divided into two types: regular filling type and constant volume filling type, which are only suitable for filling low viscosity gas-free liquids such as milk and wine.
 
Pressure filling machines
The pressure filling machine carries out filling at higher than atmospheric pressure. It can be divided into two types: one is that the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the liquid flows into the bottle by its own weight, which is called an isobaric filling. The other is that the pressure in the liquid storage tank is higher than that in the bottle, and the liquid flows into the bottle by pressure difference, which is often used in high-speed production lines. A pressure filling machine is suitable for filling gas-containing liquids, such as beer, soda, champagne, etc.
 
Vacuum filling machines
The vacuum filling machine fills the bottle at a pressure lower than the atmospheric pressure. This filling machine is simple in structure, high in efficiency, and wide in application range for the viscosity of materials, such as oil, syrup, fruit wine, etc.

General working process of liquid filling machines:
Boxes filled with empty bottles are stacked on trays, which are sent to the tray unloader by the conveyor belt, and the trays are unloaded one by one. The empty bottles are taken out of the boxes, and the empty boxes are sent to the box washer by the conveyor belt, cleaned, and then sent to the carton so that bottles containing drinks can be loaded into them. Empty bottles taken out from the box unloader are sent to the bottle washer for disinfection and cleaning by another conveyor belt. After being inspected by the bottle inspection machine, they meet the cleaning standards and then enter the filling machine and the capping machine. The beverage is filled into bottles by a beverage filling machine. Packed bottles of the beverage are sealed by capping machines and delivered to the labeling machine for labeling. After labeling, they are sent to the packing machine for loading into boxes and then sent to the pallet stacking machine for stacking on pallets and then sent to the warehouse.
