The invention relates to a waste material recycling device. The waste material recycling device comprises a base, a worktable, a bracket, a top seat, a drive motor, a first cam set, a second cam set,a transmission shaft, support rods, springs, limiting plates, breaking hammers, guide sleeves, drive balls and drive rods. The top seat is arranged at the top end of the base, the worktable is arranged on the inner end surface of the top seat, and the bracket is arranged at the top end of the top seat. The transmission shaft is fixedly connected with the output end of the drive motor, and the first cam set and the second cam set are both fixedly mounted on the transmission shaft. The guide sleeves are disposed in the bracket through the support rods, the drive rods are located in the guide sleeves, the drive balls are disposed at the top ends of the drive rods, the breaking hammers are fixedly connected with the bottom ends of the drive rods, the limiting plates are arranged on the side end faces of the drive rods, and the limiting plates are tightly connected with the support rods by the springs. According to the design, a driving structure is optimized, and in cooperation with the breaking hammers, reciprocating pressure is applied to waste materials to reduce the size of the waste materials and facilitate recycling.
