The driving force of the filling machine is transmitted from the can sealing machine to the turbine reducer through the universal joint drive shaft, and then directly meshed with the external ring gear of the can support base through the gear on the reducer, so as to realize the normal operation of the filling machine. In addition, the turbine reducer also drives the tank conveyor belt, supply screw, input star wheel, etc. The empty tank is sent by the tank conveyor belt. Through the tank brake, the synchronous supply screw is input into the star wheel to enter the tank filling station. With the transportation of the filling machine, the ideal filling can be realized, and the real tank is sent to the tank sealing machine synchronously by a special conveyor belt.
