Large yarn throwing and carrying device for three-dimensional weaving of composite material

The invention discloses a composite material three-dimensional weaving large yarn throwing yarn carrier which comprises a yarn storage pipe and a yarn outlet located in the top of the yarn carrier and further comprises a pulley block installed on one side of the yarn carrier and located below the yarn outlet, and the pulley block comprises a fixed pulley close to the yarn outlet and a movable pulley far away from the yarn outlet. A sliding rod is arranged between the fixed pulley and the movable pulley, and the axis of the sliding rod is parallel to the axis of the yarn storage tube; the sliding rod is sleeved with a tension spring, and the movable pulley moves up and down along the sliding rod. During knitting, yarn extends out of the yarn storage tube, penetrates through the yarn storage tube, is wound on the movable pulley and the fixed pulley and then penetrates out of the yarn outlet, and when the movable pulley is located at the position closest to the fixed pulley, the tension spring is compressed, and
