The invention discloses a short-process no-drafting wool-gathering spinning device, and the device comprises a feeding part, a combing cleaning part, a conveying and gathering part, and a twisting winding forming part. The feeding part comprises an upper feeding cotton plate, a lower feeding cotton plate, a cotton feeding roller, and an adjustment mechanism which is used for adjusting the distance between the upper and lower feeding cotton plates. The combing cleaning part comprises a cover plate and a carding roller disposed in the cover plate. The cover plate is provided with a feeding port, a discharge hole, and a trash removing port. The conveying and gathering part comprises a fiber conveying tube, a wool gathering notch disposed at the tail end of the fiber conveying tube, a negative pressure tube equipped with an air draft groove, a front roller located at a side of the negative pressure tube, grid rings which sleeve the negative pressure tube and the front roller, and a preliminary roller contacting with the front roller. The device is short in spinning process, is high in efficiency, is small in number of technological control points, saves production cost for a spinning enterprise, makes the most of ceiba, fallen wool, noil, recycle cotton and other super-short fine flexible fiber in an optimized manner. Wool-gathering spinning through the device gives consideration to advantages of the compact spinning and ring spinning.
