The invention relates to the technical field of spinning, and discloses a yarn anti-breaking intelligent manufacturing device for spinning. The yarn anti-breaking intelligent manufacturing device comprises a supporting frame, a supporting plate is rotatably connected to the top of the supporting frame, a transmission shaft is fixedly connected to the bottom of the supporting plate, and a transmission bevel gear is fixedly connected to the bottom of the transmission shaft. A main shaft is fixedly connected to the bottom of the transmission bevel gear, a transmission wheel is fixedly connected with the bottom of the main shaft, and a connecting bevel gear is connected to the exterior of the transmission bevel gear in a meshing mode. The transmission shaft, the transmission bevel gear, the main shaft, the transmission wheel, the connecting bevel gear, a movable frame, a connecting gear, a pressure rod, a pressure spring and a brake ring are used in cooperation, so that the effect of braking and buffering is achieved, yarn breakage is effectively avoided, the yarn protection effect during spinning is improved, the situation that the yarn protection degree is insufficient due to the limited buffering stroke is effectively avoided, the spinning quality is improved, the trouble of re-piecing is avoided, and the spinning work efficiency is improved.
