can filling machine is suitable for filling and sealing effervescent pop can beverages in the industries of pop can beverages (beer) . The filling and seaming are of integral design . The principle of equal pressure filling is adopted . During the filling , after the empty can reaches into the can lifting cylinder after passing through the pneumatic triplex parts , and the empty can is raised and the conical seal gasket under the filling valve is sealed . The position turning block of the filling valve turns the position and opens the valve under the action of another cylinder . The air is filled into the empty can to form equal pressure . From a large material barrel , the beer passes through 14 small conduits and flows into the empty can . When the liquid level in the empty can blocks the gas return pipe mouth , the filling stops . Under the action of ram , the defoaming valve will slowly discharge the air and pressure .
