The first preset condition may be that the operation duration or the number of operation turns of the double-split drawing machine head 1 reaches a preset value, or that a yarn group wound around the double-split drawing machine head 1 meets a preset condition, for example, the thickness of the yarn group reaches a preset thickness value or the weight of the yarn group reaches a preset weight value.

In the embodiment provided by the invention, the single-head double-split cake winder further comprises a yarn group detection mechanism 6 in signal connection with the controller 5, and the yarn group detection mechanism 6 is used for detecting yarn group signals on the double-split machine head 1 and sending detection results to the controller 5 in real time. The controller 5 controls the orderly operation of the cutting mechanism 4 according to the received detection result of the yarn group detection mechanism 6.

In this embodiment, the first preset condition includes: the detection value of the yarn group detection mechanism 6 satisfies a second preset condition. For example, the detection value of the yarn package detection mechanism 6 is larger or smaller than a preset detection value.

In an alternative embodiment, the yarn group detecting mechanism 6 comprises a pressure sensor or a distance sensor for detecting the yarn group weight of the yarn group of the yarn cake twine on the double-split drawing head 1 or the yarn group diameter of the yarn cake twine on the double-split drawing head 1, and correspondingly, the second preset condition comprises: the detection value of the pressure sensor is greater than the preset pressure value or the detection value of the distance sensor is smaller than the preset distance value.

At this time, if the yarn group detection mechanism 6 detects a distance signal of the surface of the yarn group, that is, when the yarn group detection mechanism 6 detects that the distance of the surface of the yarn group is smaller than a preset value, the controller 5 judges that the diameter of the yarn group reaches the preset diameter according to the detection result, at this time, the controller 5 controls the cutting mechanism 4 to cut off the yarn, and then controls the double-split drawing machine head 1 to stop running. If the yarn group detection mechanism 6 detects a pressure signal, when the extrusion force of the yarn group on the double-split drawing machine head 1 on the yarn group detection mechanism 6 reaches a preset value, the controller 5 can judge that the diameter of the yarn group reaches the preset value or the weight of the yarn group reaches the preset value according to the detection result, so that the controller 5 controls the cutting mechanism 4 to cut off the yarn, and then controls the double-split drawing machine head 1 to stop running.

Practical production verifies that the distance between the two tension rods is 4 cm-5 cm, the practical use effect is the best at present, and the length of the tension rod can be selected to be 15 cm.

Referring to fig. 1, the tension adjusting mechanism 3 further includes a plurality of tension rollers 33, and the yarn sequentially passes around the plurality of tension rollers 33 during the yarn winding process. The yarn is wound around a plurality of tension wheels 33 in sequence so as to obtain the tension of the yarn in the spinning process, thereby judging whether the position of the tension rod 32 needs to be adjusted.
