The invention relates to a stripping device, particularly relates to a waste cable sheath stripping device, and aims at solving the technical problem of providing the waste cable sheath stripping device. To solve the technical problem, the waste cable sheath stripping device comprises a bottom plate and the like, wherein assembly plates are arranged on front and back sides on the left side of the top of the bottom plate, and a take-up device is arranged between the assembly plates; a first strut is arranged at the top of the bottom plate; a cutting device is arranged at the top of the first strut; a collection groove is formed in the left side of the first strut at the top of the bottom plate; a conductor of the cable is coated with a sheath; the conductor and the sheath of the cable run through the cutting device; and the conductor of the cable winds the take-up device. The waste cable sheath stripping device achieves the effects that the sheath can be quickly and efficiently stripped with machinery instead of manual work, so that work load of workers can be reduced, and air pollution cannot be caused; and the cable sheath can be cleaned due to a cleaning device.
