Automatic skein splitting and binding device of skein reeling machine

The invention discloses an automatic hank yarn splitting and binding device of a hank reeling machine, which comprises a yarn threading rod and a threading device, the yarn threading rod is used for splitting hank yarns on a yarn frame, the threading device comprises an upper spraying and suction nozzle and a lower spraying and suction nozzle which have the same function, two air pipes are respectively introduced into the spraying and suction nozzles, one air pipe is a suction pipe, and the other air pipe is a spraying pipe. One end of the suction pipe is connected to the nozzle opening, the other end of the suction pipe is connected to a negative pressure generator, negative pressure is generated in the suction pipe through the negative pressure generator to suck yarn, the spray pipe is connected to a flow channel facing the nozzle opening, and air sprayed out of the spray pipe can blow out the yarn in the suction pipe when flowing out of the nozzle opening. According to the device, the functions of automati
