The invention discloses a puffing device with double-motion wheels and a middle net guide rod used for accelerating polymer dissolution. The puffing device with the double-motion wheels and the middle net guide rod used for accelerating the polymer dissolution is characterized by comprising a power system, a movement conversion system, a vibration source system and a container. The power system is formed by the connection of a motor, a driving wheel and a driven wheel, the movement conversion system is composed of a beating rod, a contactor, a return spring, a middle net guide rod and a middle net frame, the beating rod is arranged on the driven wheel, the contactor is fixed on middle net frame, the return spring and the middle net guide rod are arranged on two sides of the middle net frame, and the middle net guide rod penetrates through the middle net frame and the return spring and is fixed on the container. The vibration source system is composed of an end net frame and a plurality of metal wires fixed on the end net frame, and the metal wires on the end net frame are tightened on the container by two ends of the end net frame through a digging line and an extension spring. According to the puffing device with the double-motion wheels and the middle net guide rod used for accelerating the polymer dissolution, the polymer dissolution time can be shortened, the size of equipment required by the polymer preparation is reduced, and the occupied space and load-bearing on a marine platform are reduced.
