Automatic 250ml cold soda water carbonated beverage drink canning machine beer can filling sealer production for sale line

The cans enter the filling machine through the inlet star wheel and reach the predetermined center behind the can table, then the filling valve descends along the support cam to align and pre-pressure seal the cans, the sealing pressure is generated by a cylinder pressurized in addition to the weight of the centering cover itself, the air pressure in the cylinder can be adjusted by the pressure reducing valve on the gas control cabinet, the pressure is 0~40KPa (0~0.04MPa), the size of the pressure depends on the material of the cans. While opening the vacuum channel, the back pressure gas in the filling cylinder rushes into the tank and flows into the vacuum channel. Evacuation is used to implement the CO2 flushing procedure to remove the air from the cans. Through this procedure, the material is filled with minimum oxygenation and no negative pressure is generated in the cans, so even aluminum cans with very thin walls can go into the CO2 flushing.

For filling without vacuum, the filling machine can directly use the CO2 gas from the original vacuum channel to flush the cans directly. After the vacuum valve is closed, the can and the cylinder establish equal pressure, the liquid valve is opened by the spring and the filling starts. Through the three inlet slots, the material goes down the can wall, while the gas inside the can returns to the filling cylinder through the gas valve. By changing the length of the gas return pipe, the height of the filling liquid level is changed. When the liquid level of the material reaches the return tube, the return air is blocked and the filling stops, creating an overpressure in the upper gas part of the tank, thus preventing the material from continuing to flow down. Pull fork to close the gas valve and liquid valve, through the exhaust valve, the exhaust makes the pressure in the can balanced with the atmospheric pressure, the exhaust channel is far away from the liquid level, thus preventing the exhaust from bringing out the liquid. During venting, the gas at the top of the tank expands and the material in the return pipe falls back into the tank, emptying the return pipe. At the moment of discharging the can, the centering cover lifts up under the action of the cam, and the can leaves the can table under the action of the inner and outer guards and enters the capping machine delivery chain to the capping machine.
