The invention relates to an efficient filling machine which comprises a bracket, a conveyor belt, a limiting mechanism, filling bottles, an air cylinder I, an air rod I, an air cylinder II, an air rod II, a positioning frame, a filling spray nozzle, an inductor and a metering mechanism, wherein one end of the air rod I is connected to the air cylinder I; the other end of the air rod I is connected to the positioning frame; one end of the air rod II is connected to the air cylinder II; the other end of the air rod II is connected to the positioning frame; the filling spray nozzle is mounted below the air rod I; and the inductor is mounted on the limiting mechanism. The efficient filling machine is characterized in that the front end of the positioning frame is provided with a baffle rod, wherein a sensor is arranged at the rear side of the positioning frame. The efficient filling machine is arranged, so that a liquid is automatically conveyed and filled into the filling bottles, quantitative filling is carried out according to the filling weight, and the plurality of filling bottles are simultaneously positioned for filling the liquid, and therefore, labor power transfer is reduced, production efficiency is improved, and production cost is reduced.
