The invention discloses a transporting device for reel-manufacture composite filaments. The transporting device for the reel-manufacture composite filaments is composed of a drive system, a braking system and a control system and comprises a transmission shaft, a power roller, a pneumatic valve, a control device and the like. A transmission device is installed on a rack which is located at the bottom of a reeling machine. The transmission device is used for transporting yarns when composite filaments are reeled and manufactured. Compared with the traditional transporting device, the transporting device for the reel-manufacture composite filaments has the advantages that after silk yarns are broken, braking is quick, and appearing bar tacks caused by repeatedly winding of the transported yarns is prevented.
