[0015] When implementing: Figure 1-5 As shown, a screening device for the production of NdFeB magnets comprises: a support frame 1, a shell 2 is fixedly connected to the top of the support frame 1, a vibration motor 201 is arranged on one side of the shell 2, two screening material components 3 are arranged inside the shell 2, a dust collecting component 4 is arranged at the bottom of the shell 2, the two screening material components 3 divide the interior of the shell 2 into three material chambers, a discharge pipe 202 in which two of the material chambers are connected is arranged on the surface of the shell 2, and the setting height of the two discharge pipes 202 is respectively located above the two screening material components 3; wherein, the screening material component 3 comprises a partition plate 301 arranged inside the shell 2, and the surface of the partition plate 301 is provided with evenly distributed sieve holes 302.

[0016] Among them, a slot is provided on one side of the outer shell 2 for introducing raw materials to be screened. The waste material is introduced into the top of the uppermost screening component 3 through the slot, and the vibration motor 201 is started to drive the material to vibrate and move inside the outer shell 2. In this process, the sieve hole 302 can be used to screen it, so that it can be screened into materials of various specifications for subsequent use.

[0017] like Figure 1-5 As shown, the partition plate 301 is slidably connected to a connecting plate 303, and two symmetrically distributed mounting rods 305 are fixedly connected to the surface of the connecting plate 303. A baffle plate 306 that is evenly distributed and corresponds to the sieve holes 302 is arranged between the two mounting rods 305. A connecting rod 307 is fixedly connected between two adjacent baffle plates 306, and the baffle plate 306 is fixedly connected to the mounting rod 305 via the connecting rod 307.

[0018] The opening cross section of the baffle 306 is equal to the opening cross section of the sieve hole 302 , and the baffle 306 blocks part of the opening of the adjacent sieve hole 302 .

[0020] By rotating the threaded rod 304, the connecting plate 303 can be driven to slide along the surface of the partition plate 301. In this process, the mounting rod 305 can be driven to move synchronously, thereby changing the interleaving area between the partition plate 301 and the sieve hole 302, and further changing the specifications of the material that can pass through the sieve hole 302. The adjustment can be made according to actual usage, and the operation is simple. The application range of the device is effectively improved.

[0024] When the present invention is in use, the connecting plate 303 can be driven to slide along the surface of the partition plate 301 by rotating the threaded rod 304, and in this process, the mounting rod 305 can be driven to move synchronously, so that the interlaced area between the partition plate 301 and the sieve hole 302 can be changed, and then the specifications of the materials that can pass through the sieve hole 302 can be changed. The device can be adjusted according to actual use conditions, and the operation is simple, which effectively improves the application range of the device. The setting of the guide rod 308 can make the connecting plate 303 more stable during the movement process. By starting the fan 405, the airflow can be guided from the inside of the outer shell 2 through the sieve hole 302 and the discharge shell 401 and through the filter screen 403 into the inside of the installation shell 402, and finally discharged through the through groove 406.
