The stirring blade 25 revolves and the lead screw 10 rotates. Due to the hollow rod 9, the lead screw 10 also moves up and down while rotating, which further allows the strip box 8 and the rotating rod 11 to move up and down. Thus, the rotating rod 11 and the stirring blade 25 can move up and down while revolving. The second motor 24 drives the second gear 20 to rotate, which in turn drives the two third gears 21 to rotate. The rotation of the two third gears 21 drives the two second belts 23 and the four second pulleys 22 to rotate. The rotation of the two second pulleys 22 drives the two rotating rods 11 to rotate on their own axis. Therefore, in use, the rotating rod 11 and the stirring blade 25 can move up and down, rotate on their own axis, and revolve synchronously, thereby improving the efficiency of the equipment.
