starting the second winding assembly 20B to enable the second winding assembly 20B to run reversely, so that the second winding assembly 20B does not fix the broken yarn any more, and the waste yarn in the second winding assembly 20B drops, starting the driving part, driving the detection disc 30 to rotate through the driving part, driving the tension sensor 11 and the stretching mechanism 40 to rotate through the detection disc 30, driving the first winding assembly 20A and the second winding assembly 20B to rotate through the tension sensor 11 and the stretching mechanism 40, enabling the first winding assembly 20A to rotate from the point B1 to the point B2, enabling the second winding assembly 20B to rotate from the point B2 to the point B1, and enabling the first winding assembly 20A to pull the yarn fixed in the first winding assembly in the rotating process and drive the yarn in the first winding assembly to move to the point B2;
after the second winding assembly 20B moves from the point B2 to the point B1, the yarn at the point B1 is located inside the second winding assembly 20B, the second winding assembly 20B is started, so that the second winding assembly 20B fixes the yarn inside the second winding assembly 20B, the stretching mechanism 40 is started, the second winding assembly 20B is driven to move by the stretching mechanism 40, and the yarn is tested for the second time under the cooperation of the tension sensor 11;
after the second test is finished, starting the first winding component 20A located at the position B2 to enable broken yarns inside the first winding component 20A to fall off, starting the driving part to enable the detection plate 30 to rotate reversely, further driving the first winding component 20A to return to the point B1 from the point B2, and driving the yarns inside the second winding component 20B to return to the point B2 from the point B1, so that a test process is finished;
the operation is circulated, so that the first winding assembly 20A and the second winding assembly 20B perform intermittent reciprocating motion, and the yarn can be continuously tested under the cooperation of the tension sensor 11, thereby effectively improving the detection efficiency.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention. Structures, devices, and methods of operation not specifically described or illustrated herein are generally practiced in the art without specific recitation or limitation.
