The method of parting according to any one of claims 1 to 5, wherein The method comprises the following steps: the operator manually feeds one or more strands of twisted yarn through the tensioner into the broken yarn detection device and clamps the yarn through the yarn feeding finger cylinder device for the first time; and according to the process requirements, the beaming length that needs to be divided is set, and then the equipment is started to run, when the running length reaches the set length, the dividing reed cylinder is lifted to the upper position of the dividing, after the dividing reed is lifted, the front and rear yarn feeding lifting cylinders are lifted to the upper position of the dividing, the yarn feeding linear module and the yarn feeding rod rotary support are simultaneously actuated, and the yarn feeding rod is moved to the front end according to the trajectory of the yarn feeding rod, at this time, the yarn feeding rod cylinder drives the yarn feeding rod to the front end, the first yarn clamping cylinder drives the connecting rod to close the clamp to clamp the twisted yarn between the tensioner and the yarn feeding finger cylinder device, then the yarn feeding rod returns to the original position according to the original path, at this time, the first yarn pulling cylinder is lifted, and the yarn pushing cylinder is extended to push the twisted yarn to the front end; the yarn hooking cylinder is extended, and the yarn pressing cylinder is lowered at the same time, the twisted yarn is pressed into the middle of the two yarn hooking needles, the yarn hooking cylinder is retracted, then the yarn feeding cylinder is lowered to the lower position of the dividing, the dividing cylinder is retracted at the same time, the yarn feeding cylinder is lowered to the lower position of the dividing, the twisted yarn cylinder at the diamond-shaped device is lifted to raise the twisted yarn stop lever, at this time, the diamond-shaped cylinder moves backward, the twisted yarn moves backward to the end under the action of the twisted yarn stop lever, the diamond-shaped action is completed, the yarn feeding rod sends the clamped twisted yarn to the knotting device again according to the original movement trajectory, at this time, the knotting cylinder is extended, and the yarn clamping cylinder clamps the twisted yarn, then the yarn clamping cylinder is retracted to the original position together with the twisted yarn, the clamp at the head of the yarn feeding rod is opened under the action of the connecting rod driven by the yarn clamping cylinder, the twisted yarn is released, the yarn feeding rod returns to the original position according to the original path, at the same time, the yarn clamping device is opened, the suction nozzle is opened, the second yarn pulling cylinder is lifted to cut the twisted yarn at the tensioner, the twisted yarn enters the suction nozzle under the action of the suction nozzle, the yarn feeding finger cylinder device clamps the twisted yarn, the second yarn pulling cylinder is lowered, then the lifting cylinder drives the knotter to lift the yarn into the knotter to complete the twisted yarn knotting, at the same time, the waste yarn suction nozzle is opened, the cut waste twisted yarn is sucked away, thereby completing the dividing action; the dividing reed cylinder returns to the middle position, and the equipment is started to run again.
