The invention relates to a thread fixing device on textile equipment, which comprises a fixed plate, wherein the front side of the fixed plate is provided with a transverse inverted T-shaped chute; aplurality of inverted T-shaped sliding blocks are movably arranged in the inverted T-shaped chute; the inverted T-shaped sliding blocks can respectively slide left and right along the inverted T-shaped chute; adjacent sides of adjacent inverted T-shaped sliding blocks are fixedly connected through a first spring respectively; the front sides of the inverted T-shaped sliding blocks are fixedly connected with the rear side of a connecting plate respectively; the front sides of the connecting plate are fixedly connected with the middle part of the rear side of a mounting plate respectively, and guide plates are respectively arranged in the middle of the upper parts of the adjacent mounting plates. According to the device, yarns and cotton threads with different thicknesses can be combed at the same time; whether the yarns and the cotton threads are inclined or knotted can be automatically distinguished; when the knotting phenomenon occurs, an alarm flash lamp at a corresponding position flashes to alarm, finding out the position of the yarns and the cotton thread quickly for the monitor is facilitated, thereby improving the textile production efficiency, meeting the market demand andbeing suitable for popularization.
