The invention relates to a packaging machine for producing cables. A paying-off end and a taking-up end are sequentially arranged on a support, the paying-off end comprises a weighing machine and a conveying belt, a transitional pulley is arranged above the weighing machine, and the taking-up end comprises a movable block and a rotary shaft; a first through hole is formed in the movable block, a length counter is arranged in the first through hole, through holes are evenly formed in the rotary shaft, and a limiting rod matched with the through holes is arranged; one end of the rotary shaft is connected with a motor, a circular fixed block sheet is fixed to the position close to a motor end, the rotary shaft penetrates through the center of the fixed block sheet, and holes are evenly and circumferentially distributed in the fixed block sheet; and backup rollers are arranged in the holes in a penetrating mode, the ends of the backup rollers are arranged to be spheres, the diameter of each sphere is larger than the diameter of the corresponding hole, and a movable block sheet is arranged corresponding to the fixed block sheet. According to the packaging machine for producing the cables, the structural design is reasonable and simple, the automation degree is high, the operating efficiency is improved, and the production cost is reduced; and meanwhile a coil can be dismounted from one side of a take-up reel at any time, the storage space is saved, environmental protection is achieved, and the packaging machine is easy to promote.
