This machine is developed on the basis of digestion and absorption of domestic and foreign (non-gas) cans filling and sealing machine (sealing machine). According to the principle of atmosric pressure filling, when empty tank enters the lifting tray through the pulley, the filling valve and empty tank are aligned, the empty tank is lifted and sealed, and the valve opening of filling valve is opened automatically. When the filling liquid level blockades the return pipe opening of the valve, the filling stops.
