The invention discloses a recycling device of waste leather. The recycling device structurally comprises a supporting frame, a crushing driving wheel, a feeding hopper, a crusher body and a discharging apparatus, wherein the crusher body is welded in the middle part of the top end of the supporting frame in an embedding manner, the left end of the crusher body is connected with the crushing driving wheel in a locking manner, the top end of the crusher body is connected with the feeding hopper in a locking manner, the bottom end of the crusher body is connected with the discharging apparatus ina locking manner, the discharging apparatus comprises a discharging hopper, a discharging material inlet, an air guide apparatus, an absorption apparatus, an air outlet filter plate, an exhaust connecting pipe, a particle collection hopper, a collection hopper supporting plate and a discharging opening. When in use, 1, the leather chippings can be absorbed by virtue of the electrostatic absorption apparatus, so that the chippings produced when the leather is recycled and crushed can be prevented from flying, the chippings can be safely collected, and the inconvenience caused by the flying andadhesion of the chippings can be prevented; and 2, when the electrostatic absorption is performed, the chippings can be guided, so that the backfilling phenomenon of the chippings due to the air flowcan be better prevented, and the use is facilitated.
