[0048] Furthermore, a screening method for producing magnetic materials comprises the following steps:

[0049] S1, preliminary screening: put the material into the preliminary screening box 102, turn on the first motor 203a, the output end of the first motor 203a drives the connecting bevel gear 203d and the transmission bevel gear 203e to rotate through the starting bevel gear 203c, and then drives the preliminary screening box 102 to move horizontally along the chute 105 on the working box 101 through the swing rod 208 to perform preliminary screening on the material;

[0050] S2, preventing material clogging: the connecting rod 204a drives the connecting gear 204b to rotate clockwise, and drives the transmission gear 204c to rotate through the meshing block 204e, and then drives the half gear 204f to move synchronously. When the screening is paused or the first motor 203a is driven in reverse, the transmission gear 204c and the connecting gear 204b exit the meshing state, and then the knocking rod 205 is driven by the half gear 204f to knock the primary screening box 102 under the action of the torque spring, and the vibration makes the material stuck in the screen mesh disengage;

[0051] S3. Material return and collection: When the material falls onto the secondary screening plate 301, it will be screened again.

The material remaining on the secondary screening plate 301 will be returned and screened by the threaded elevator 304 to avoid the situation where the material that meets the specifications is not collected due to a large amount of large particles remaining on the screen plate.

[0052] During use, the material is placed in the primary screening box 102, and the first motor 203a is turned on. The output end of the first motor 203a drives the connecting bevel gear 203d and the transmission bevel gear 203e to rotate through the starting bevel gear 203c, and then drives the primary screening box 102 to move horizontally along the slide 105 on the working box 101 through the swing rod 208 to perform preliminary screening of the material. At the same time, the connecting rod 204a drives the connecting gear 204b to rotate clockwise, and drives the transmission gear 204c to rotate through the meshing block 204e, and then drives the half gear 204f to move synchronously. When the screening is paused or the first motor 203a is driven in reverse, the transmission gear 204c and the connecting gear 204d are driven to rotate clockwise. The connecting gear 204b exits the meshing state, and then under the action of the torque spring, the knocking rod 205 is driven by the half gear 204f to knock on the primary screening box 102, and the vibration causes the material stuck in the screen to fall out. When the material falls to the secondary screening plate 301, it will be screened again. The material that meets the specifications will be pushed into the collection box 103 by the collecting plate 307e driven by the first connecting rod 307c and the second connecting rod 307d under the action of the connecting plate 307b. The material remaining on the secondary screening plate 301 will be returned and screened by the threaded elevator 304 to avoid the failure to collect the material that meets the specifications due to the large amount of large particles remaining on the screen plate.
