The invention relates to the field of textile processing, and discloses an efficient yarn carding machine. The efficient yarn carding machine comprises a rack, a yarn leading mechanism and a yarn combing mechanism, the yarn leading mechanism and the yarn combing mechanism are arranged on the rack, the yarn leading mechanism comprises a closing part, a first traction component, a yarn pressing component and a second traction component, the closing part and the first traction component are arranged on an upper yarn combing frame of the yarn combing mechanism in sequence, and the yarn pressing component and the second traction component are arranged on a lower yarn combing frame of the yarn combing mechanism in sequence; the yarn combing mechanism comprises a yarn combing procedure component in a lower base, a yarn combing restoration component arranged in an upper base, multiple combs which are circularly delivered between the yarn combing procedure component and the yarn combing restoration component, a first upper component which achieves connection of the tail end of the yarn combing procedure component and the initial end of the yarn combing restoration component, and a second upper component which achieves connection of the tail end of the yarn combing restoration component and the initial end of the yarn combing procedure component. The yarn leading mechanism of the efficient yarn carding machine is smooth and efficient in yarn leading, and is not prone to knotting; the circular yarn combing efficiency of the yarn combing mechanism is high.
