The invention provides a spinning channel for rapidly curing gel fibers. The spinning channel comprises a spinning nozzle arranged at the center of the top of the spinning channel; the spinning channel body is arranged below the spinning nozzle, the spinning channel body comprises a plurality of cylindrical spinning channel sections which are coaxially arranged, each spinning channel section comprises a plurality of air inlets which are annularly arranged on the inner wall of the upper part of each spinning channel section, and hot air flow is supplied into the spinning channel sections through the air inlets; the return air inlets are annularly formed in the inner walls of the lower portions of the channel sections, and hot air flow in the channel sections is exhausted through the return air inlets. The gel fiber spinning device can accelerate the drying and curing of gel fibers, reduce the liquid dropping phenomenon, avoid the problems of adhesion, breakage and the like of fiber tows, improve the spinning s
