The application provides a winding core spinning device based on a calculus principle and a method and application thereof. The device is provided with a negative pressure air suction port on a special-shaped plate, and a corresponding negative pressure airflow guide assembly is arranged above the negative pressure air suction port. Under the mutual cooperation of the diffusion flow guide hole and the negative pressure air suction mechanism, the spread fiber type short fibers with a certain width and uniformly distributed fiber height parallelism are obtained on the grid ring. Meanwhile, the short fiber sliver, core yarn and winding core yarn form a "y" shape structure in the winding core wrapping area. The core yarn self-rotation drives the short fiber sliver to be tightly wrapped and wound to the outer layer of the core yarn in the winding core wrapping area to form the winding core yarn. Then, the winding core yarn passes through the soft reinforcing winding core part, so that the wrapping layer is tightly attached to the yarn body under the action of temperature and pressure to form a good wrapping effect. The winding core yarn has a compact yarn body and a large core yarn proportion, solves the problems of small wrapping tightness, many wrapping exposed cores and low core yarn proportion of the core-spun yarn on the ring spinning machine, and greatly improves the yarn quality.
