The invention relates to the technical field of sizing machines, in particular to an intelligent high-speed sizing machine which comprises a beam creel, a slurry tank, a drying room, a URM (Ultrasonic Rapid Manufacturing) device, a lease region and a nose. The intelligent high-speed sizing machine is sequentially provided with the beam creel, a yarn guide roller, the slurry tank, the drying room, the URM device, the lease region and the nose along the movement direction of yarns; a pan head and a support plate assembly are arranged on the beam creel, the slurry tank is connected with the yarn guide roller which is connected with a squeezing roller, the drying room is connected with the URM device which is connected with the lease region, the lease region is connected with the nose, the drying room is internally provided with a pre-drying barrel and a main-drying barrel, a smoke hood is arranged above the pre-drying barrel and the main-drying barrel, and the pan head is arranged in the nose. According to the invention, a pressure sensor is arranged on the yarn guide roller, the tension of the yarns entering the slurry tank can be detected; the sizing speed can be regulated at any time through the nose; and thus the sizing rate is ensured and the warp weaving performance is improved.
