The invention relates to a winding device, in particular to a waste cable winding device. The technical problem is that the waste cable winding device provided by the invention has the characteristics that waste cable winding is carried out through the device instead of manpower, so that the working efficiency cannot be affected due to the ache of hands, and the hands do not need to be in contact with a waste cable, so that the hands are not easy to be damaged by the waste cable. According to the technical scheme, the waste cable winding device comprises a base, a rear side plate, a first bearing beat, a servo motor, a first rotating shaft, sliding blocks and the like, the rear side plate is arranged on the rear side of the middle of the top of the base, the first bearing beat is embedded in the upper portion of the rear side plate, and the first rotating shaft is arranged on the first bearing beat. According to the device, one end of the waste cable is placed in a containing hole, the servo motor is started to rotate anticlockwise, a pressing plate moves outwards, so that the waste cable is pressed and fixed, and meanwhile, a first contacting plate drives a cylinder to rotate anticlockwise, so that the waste cable is wound up, manual winding of the waste cable is not needed, time and labor are saved, and hands are prevented from being damaged by the waste cable.
