[0045] The top of the sliding plate 3 is fixedly connected with a first support 55, and the top of the first support 55 is fixedly connected with a first bearing 52.

[0046] The outer wall of the first bearing 52 is rotatably connected with a rotating rod 53, and the magnetic attraction block 57 magnetically attracts the iron filings on the rotor, so that the iron filings on the rotor are magnetically attracted down. The second spring 65 is arranged to lift the limiting block 61, so that the lifting roller 62 rises to lift the rotating ring 56. The lifting of the rotating ring 56 in turn causes the magnetic attraction block 57 to approach the rotor. The magnetic attraction block 57 magnetically attracts the iron filings on the rotor, so that the approach of the magnetic attraction block 57 and the rotor in turn increases the effect of magnetic adsorption, accelerates the falling of the iron filings, and the outer wall of the rotating rod 53 is sleeved with a first rotating roller 54. The first rotating roller 54 is fixedly connected with the first spring 51 between the inner wall of the first rotating roller 54 and the outer wall of the rotating rod 53.

[0048] The top of the sliding plate 3 is fixedly connected with a lifting device 6 at the position of the rotating ring 56, the lifting device 6 comprises a limiting plate 64, the inner wall of the limiting plate 64 is inserted with a limiting block 61, the second spring 65 is fixedly connected between the limiting block 61 and the limiting plate 64, the outer wall of the limiting block 61 is fixedly connected with a second bearing 63, and the limiting block 61 is rotatably connected with a lifting roller 62 through the second bearing 63. The lifting roller 62 is in movable contact with the rotating ring 56.

[0049] The outer wall of the sliding plate 3 is fixedly connected with a storage device 9 near the position of the rotating ring 56, the storage device 9 comprises a storage box 95, the storage box 95 is fixedly connected to the outer wall of the sliding plate 3, a hole is formed in the outer wall of the storage box 95, a door plate 94 is hingedly connected to the outer wall of the storage box 95 at the position of the hole, a horizontal rod 93 is fixedly connected to the inner wall of the storage box 95, a fourth spring 92 is fixedly connected to the outer wall of the horizontal rod 93, a cotton scraping piece 91 is fixedly connected to the outer wall of the fourth spring 92, and the cotton scraping piece 91 is in movable contact with the magnetic block 57.

[0050] When in use, the magnetic block 57 is located between the two balancing devices 2, and is located at the bottom of the rotor. The magnetic block 57 is magnetically attracted to the iron filings on the rotor, and the second spring 65 is arranged to lift the limiting block 61, thereby lifting the top roller 62 to lift the rotating ring 56, and the lifting of the rotating ring 56 in turn causes the magnetic block 57 to approach the rotor. The second bearing 63 is arranged to rotate with the rotating ring 56, and the top roller 62 is arranged to keep the rotating ring 56 lifted, thereby causing the magnetic block 57 to continuously magnetically attract the rotor. The magnetic block 57 is made of soft magnetic material, so it can deform. The fourth spring 92 is arranged to cause the scraping cotton 91 to adhere to the rotating ring 56. The scraping cotton 91 is made of sponge material, so when it adheres to the outer wall of the rotating ring 56, it can clean the iron filings on the magnetic block 57.

When the second motor 58 is energized and started, it drives the second rotating roller 59 to rotate, and the first rotating roller 54 is connected through the first spring 51, the rotating rod 53 and the first bearing 52, thereby causing the second rotating roller 59 to drive the rotating ring 56 to rotate, changing the position of the magnetic block 57, so that the scraping cotton 91 can clean the iron filings adhered to the magnetic block 57. Through the arrangement of the groove 8, when the groove 8 rotates to the top position of the rotating rod 53, the first rotating roller 54 descends more under the pressure of the rotating ring 56, so that the left side of the rotating ring 56 is tilted. Then when the rotating rod 53 continues to rotate and the groove 8 rotates to the bottom position of the rotating rod 53, the sinking amplitude of the first rotating roller 54 is smaller than that of the groove 8, so that the rotating ring 56 swings during the rotation of the first rotating roller 54. The swinging of the rotating ring 56 causes the magnetic block 57 to change the direction of magnetic attraction. Different directions of magnetic attraction can vibrate the iron filings in different directions of the rotor gap for magnetic attraction. Moreover, the airflow generated by the fan blade 44 during rotation causes the iron filings to move, which, combined with the magnetism of the magnetic block 57, accelerates the falling of the iron filings.

Any person skilled in the art can make equivalent replacements or changes within the technical scope disclosed by the present application and according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
