Auto quantitative filling machine for cream like materials

The utility model discloses an automatic pasty material dozing and filling machine. On a machine frame (1), a feeding stop valve (10), a material tank (9) and a discharge stop valve (11) are linked by pipelines respectively; the piston rod (5) of the material tank is connected with the piston rod (6) of a cylinder on the machine frame; a magnet is arranged in the inner cavity of the cylinder; a magnetic switch (8) is arranged on the outer periphery of the cylinder (7); a proximity switch (12) is arranged on a discharge pipe. The feeding stop valve, the discharge stop-valve, the inlet pipe and the exhaust pipe of the cylinder are respectively communicated with the pneumatic electromagnetic valve, the inlet pipe and the exhaust pipe which are connected with the machine frame. The accurate control of the automatic quantitative filling of the sealant in the packaging barrel by the feeding stop valve, the discharge stop-valve and the material tank is achieved by the accurate switchingover control of the pneumatic
