The invention provides a recycling dismantling machine for waste wires, comprising a body and a wire core-sheath separation receiving box; the body is of a box-type structure; a speed regulating motor, a feed port, a discharge port and at least one wire trimming mechanism are arranged on the body. According to the technical solution, the degree of automation of the equipment is increased, the working procedure is simplified, in particular, the wire feeding setting and the cutting setting in the prior technical solution are omitted, the equipment structure is more simplified and the performanceis more stable. By adopting the recycling dismantling machine, the disassembled wire sheaths and wire metal cores are automatically separated with high efficiency and automatically enter corresponding containers, thereby completely solving the technical problem that the last link in the wire dismantling production needs manual assistance in separation, really realizing integrated automation of all processes of the wire dismantling production, improving the work efficiency, and saving the labor cost; and the waste cable dismantling device is environment-friendly, energy-saving, simple in structure, easy to manufacture and stable in performance, and can clean waste cables efficiently and quickly.
