The yarn dividing rod 10 is of a tubular structure, the yarn dividing rope 35 penetrates through the tube body, the yarn dividing rope 35 separates two yarn layers formed by two shaft head yarns, and the yarn dividing rod 10 rotationally pulls the yarn dividing rope 35 to further improve the yarn dividing effect.

The structure is preferably that the periphery of the yarn separating rod 10 is sequentially sleeved with a large synchronous belt wheel 24, a sensor sheet 22, a first bearing 20 and a second bearing 11; a first sensor 23 is arranged corresponding to the sensor piece 22, and the rotating angle of the yarn separating rod 10 is sensed through the first sensor 23. The first bearing 20 and the second bearing 11 are respectively arranged on two supporting arms on the mounting base 5, and a retaining ring 13 is further arranged on the side edge of the first bearing 20 to prevent the first bearing 20 from moving in a crossing manner. The first sensor 23 is connected with the mounting seat 5 through the sensor seat 21, and the second sensor 19 is further arranged on the side edge of the mounting seat 5, so that the yarn sensing capability is further improved.

Preferably, the large synchronous pulleys 24 are connected to the small synchronous pulleys 30 through synchronous belts 27, tensioning pulleys 28 are arranged between the large synchronous pulleys 24 and the small synchronous pulleys 30, and the tensioning pulleys 28 are connected with the pulley base 26 through mounting shafts 29.
