When the convex end of the cam 13 is pressed against the bottom side of the mounting frame 12, the cam 13 can push the mounting frame 12 to move upward. When the convex end of the cam 13 is away from the mounting frame 12, the mounting frame 12 moves downward under the action of gravity. Further rotation of the cam 13 can make the mounting frame 12 reciprocate up and down, thereby vibrating the screen 11, thereby effectively performing vibration screening operations on the powdered azobisisobutyronitrile.
