Rotary process three-dimensional knitting platform capable of increasing number of carried yarns and knitting method thereof

The invention provides a rotary process three-dimensional knitting platform capable of increasing the number of carried yarns and a knitting method thereof. The knitting platform comprises inner carried yarn trays and outer carried yarn trays which are connected with the inner carried yarn trays located at the edge positions. 2*N notches are evenly formed in the edge of each inner carried yarn tray, N is a natural number which is larger than 1, every time the outer carried yarn trays are rotated by a circle, all the inner carried yarn trays are rotated by the 1/(2N) circle, and the notches in the inner carried yarn trays are sequentially in butt joint with notches in the outer carried yarn trays. By means of the three-dimensional knitting platform and the knitting method thereof, on the premise that the size of the platform is not changed, the number of the carried yarns can be changed into about N times of an original number, and three-dimensional knitting pre-forming pieces of the larger size can be knitted
