Filling process of bag-on-valve filling

The action process of bag-on-valve aerosol filling machine is mainly divided into three parts: inflation – sealing – liquid filling. From a professional point of view, it is to first lift the valve to form a vacuum state in the bottle, and then fill with gas, which is located between the bag and the aerosol tank, then put down the valve equipment to seal the mouth to prevent gas leakage, and finally fill the liquid into the bottle with strong pressure and fill it directly into the bag through the nozzle. At this time, the bag is in an expanded state and the filling work is completed.

Let’s review the workflow of ordinary aerosol filling machine (taking semi-automatic aerosol filling machine as an example):

The valve is poured into the valve machine – manually placing cans in the conveyor belt – automatic filling (set up filling capacity) prototype 3 filling heads (custom-made) – automatic drop valves – automatic valve pressing – automatic stabilization – automatic inflation – automatic spray valve – automatic cover – manual packing – shipment.

The simple aerosol filling machine is mainly composed of filling machine, sealing machine, inflator, booster pump, table, frame and pneumatic components. The filling machine is composed of liquid metering cylinder and filling head, and the inflator is composed of gas metering cylinder and charging head. The liquid metering cylinder and gas metering cylinder are fixed at the back of the table. The liquid filling head, sealing machine and inflation head are installed on the platen of the lifting column to facilitate up and down adjustment according to the height of the tank.
