The invention discloses a yarn-breaking-prevention yarn feeding device for textile equipment. A first yarn feeding roller and a second yarn feeding roller are arranged on an installation frame, and a tension adjustment mechanism is arranged between the first yarn feeding roller and the second yarn feeding roller; in the tension adjustment mechanism, an adjusting roller is arranged on an inner pipe body of a telescopic casing pipe, and an oil storage bag is located in an outer pipe body and communicates with the outside through the inner pipe body; and the two ends of an elastic reset piece are connected with a third roller seat and the installation frame correspondingly, and a textile yarn sequentially winds across the first yarn feeding roller, the adjusting roller and the second yarn feeding roller. Through the optimally-designed yarn-breaking-prevention yarn feeding device for the textile equipment, optimization of structural design is reasonable, when tension of the textile yarn is too large and force is applied to the adjusting roller, the telescopic casing pipe is compressed, and under the compressing effect of the inner pipe body, lubricating oil in the oil storage bag is extruded out and lubricate the surface of the adjusting roller through the inner pipe body, so that the textile yarn is lubricated; and friction force between the textile yarn and the adjusting roller is effectively reduced, so that the axial tension of the textile yarn is reduced, and yarn breaking is prevented.
