Machine head of warp tying machine with high-performance yarn-separating function

The invention discloses a machine head of a warp tying machine with a high-performance yarn-separating function. The machine head comprises a machine head body of the warp tying machine and is equipped with a yarn-separating device, a filament delivery device, a machine head driving device and a knotting and yarn-cutting device. The yarn-separating device comprises an upper yarn-separating rod anda lower yarn-separating rod. The end parts of yarn-separating rods are provided with tapered yarn-separating heads. The outer periphery of each yarn-separating head is equipped with a spiral yarn-separating groove. The two yarn-separating rods are driven by a yarn-separating motor to rotate. The axial direction of the two-separating rods and yarns needing to knot are in the horizontal direction.Through spiral yarn-separating grooves in the two yarn-separating rods, the technical target of separating yarns is achieved. Yarn-separating performance is improved. Technical defects are solved so that a yarn is not poked br
