The utility model discloses a filling host machine capable of conducting rechecking and weighing. The filling host machine capable of conducting rechecking and weighing comprises a machine frame, a bottle feeding idle wheel and a bottle discharging idle wheel, wherein the bottle feeding idle wheel and the bottle discharging idle wheel are arranged on the sides of the machine frame and are driven by a power mechanism to convey bottles. A rotating liquid box is mounted on the machine frame. Multiple filling valves are annularly distributed on the liquid box. The lower portion of the liquid box is connected with filling supporting tables corresponding to the multiple filling valves respectively. Two bottle weighing devices are mounted on the sides of the machine frame. One bottle weighing device is located between the bottle feeding idle wheel and the filling supporting tables. The other bottle weighing device is located between the bottle discharging idle wheel and the filling supporting tables. Bottle transfer idler wheels are further mounted on the bottle weighing devices and the filling supporting tables. Each filling valve comprises a valve body and a valve rod, wherein a filling nozzle is arranged at the bottom of the valve body, a gap between the bottom of the valve rod and the filling nozzle is a filling opening, a double-stroke air cylinder is mounted on the top of the valve body, and the top of the valve rod is in power connection with the double-stroke air cylinder. The filling host machine capable of conducting rechecking and weighing fully guarantees filling accuracy and has the advantages of being high in filling accuracy and capable of greatly lowering the reject ratio of filling.
