The utility model discloses recycled tobacco shredding equipment. The equipment comprises a material guiding wheel set, a material limiter, parallel cutting discs, a transverse shredding rolling cutter and a rack. The material guiding wheel set, the material limiter, the parallel cutting discs and the transverse shredding rolling cutter are sequentially installed in the horizontal direction. The material limiter is located on a center line between an upper roller and a lower roller of the material guiding wheel set. The whole device is arranged on the rack. Recycled tobacco is directly cut into long shreds through the parallel cutting discs and cut into short shreds through the transverse shredding rolling cutter, and the cut shreds of the recycled tobacco are uniform in length and width, and can be directly blended and used according to the cigarette formulation design ratio. The equipment simplifies the recycled tobacco shred manufacturing process, reduces tobacco damage in the recycled tobacco shred manufacturing process, and increases the utilization ratio of the recycled tobacco.
