[0004] The above technical solution drives multiple magnetic rods to rotate through a motor, and attracts the magnetic metal in the flux during the rotation. However, the magnetic rods cannot fully contact the flux during the rotation, and the surface of the magnetic rods needs to be cleaned after attracting the metal.

Therefore, the present application provides a flux screening machine to meet the needs. Utility Model Content
