[0023] The specific settings and functions of the limiting device 6 and the replacing device 7 will be described in detail below.

[0024] In this embodiment: the limiting device 6 is arranged on the upper surface of the material rack 3, and the limiting device 6 includes a limiting plate 61 and a roller 62. The limiting plate 61 is fixedly connected to the upper surface of the material rack 3, and the roller 62 is located on the upper surface of the material rack 3.

[0025] Specifically, a connecting block 64 is fixedly connected to the side surface of the limiting plate 61 , and a limiting rod 65 is fixedly connected to the upper surface of the sliding block 63 .

[0026] In this embodiment, by providing a limiting plate 61, the roller 62 can be limited, which reduces the situation where the roller 62 is prone to move left and right when the equipment is in use, making it difficult to limit the material.

[0027] Specifically, the limiting rod 65 is slidably connected to the inner wall of the connecting block 64 , and one end of the limiting rod 65 is fixedly connected to the limiting block 67 . The limiting rod 65 is provided to facilitate limiting the slider 63 .

[0028] Specifically, the surface of the limiting rod 65 is sleeved with a first spring 66 , and the two ends of the first spring 66 are fixedly connected to the surface of the connecting block 64 and the surface of the slider 63 respectively. The first spring 66 is provided to facilitate the application of a reset elastic force to the limiting rod 65 .

[0029] In this embodiment: a replacement device 7 is provided on the lower surface of the strong magnet 4, and the replacement device 7 includes a connecting plate 71 and a slide rail 72, the slide rail 72 is fixedly connected to the lower surface of the strong magnet 4, the connecting plate 71 is fixedly connected to the upper surface of the magnetic plate 5, the connecting plate 71 is slidably connected to the inside of the slide rail 72, a pull handle 77 is fixedly connected to the side of the connecting plate 71, a card slot 73 is provided inside the slide rail 72, and a support slot 74 is provided inside the connecting plate 71.

[0030] In this embodiment, the connection plate 71 is provided to connect the magnetic plate 5 and the strong magnet 4, thereby reducing the difficulty of connecting the magnetic plate 5 with the strong magnet 4 when the device is in use.

The magnetic force attracts the metal particles in the fabric to the strong magnetic device. The fabric after demagnetization does not contain metal particles. When the equipment is in use, the user pulls the slider 63, and then the slider 63 moves, which drives the limit rod 65 to move. When the limit rod 65 moves, it drives the first spring 66 to displace and deform to generate elastic force, and then the slider 63 drives the roller 62 to move. By setting the limiting device 6, the material fabric is effectively restricted, which plays a role in restricting the material fabric, reducing the risk that the material fabric will be easily affected by the strong magnet 4 when removing the metal properties when in use, causing wrinkles on the material fabric, thereby improving the practicality of the equipment.

By setting up the replacement device 7, the magnetic plate 5 is effectively replaced, which plays the role of replacing the magnetic plate 5, reduces the situation that when the device is in use, a large amount of metal particles are adsorbed on the magnetic plate 5, which is difficult to replace quickly, making it difficult for the magnetic plate 5 to adsorb metal particles to the cloth, thereby improving the practicality of the device.
