Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A yarn multi-strand cabling mechanism is shown in figures 1 to 5 and comprises a creel 1 for placing single yarns 8, a support rod 2 for providing a steering support point for the single yarns 8, a unwinding device 3 for unwinding the single yarns 8 and feeding the single yarns 8, a broken yarn detection device 5 arranged on the creel 1, a spindle 4 for twisting multi-strand yarns 9 into strands, and a controller 6 arranged on the creel 1.

After being unwound from the bobbin 7 from bottom to top, the single yarn 8 bypasses the support rod 2 and then is folded to the unwinding device 3.

The unwinding device 3 comprises a winch roller 301, a plurality of strands of yarns 9 are sequentially wound on the winch roller 301, the winch roller 301 provides power for the plurality of strands of yarns 9, at the moment, the winch roller 301 drives a single yarn 8 to feed, the single yarn 8 is passively unwound to drive the yarn drum 7 to rotate, the winch roller 301 synthesizes each single yarn 8 into the plurality of strands of yarns 9 and then feeds the plurality of strands of yarns 9 to the spindle 4, and the spindle 4 twists the plurality of strands of yarns 9 into finished yarns. In the process, the winch roller 301 provides stable power for the yarns, so that the tension of a single yarn 8 is uniform and stable during yarn feeding, and the phenomenon of 'ear yarn' of a plurality of strands of yarns 9 in the cabling process, namely strand tightness, is avoided.

The broken yarn detection device 5 comprises a broken yarn detector I501 and a broken yarn detector II 502, the broken yarn detector I501 is arranged on one side of the yarn drum 7, when the yarn drum 7 rotates and retreats yarns, the broken yarn detector I501 detects the rotation of the yarn drum 7 to judge whether a single yarn 8 is broken, and when the single yarn 8 is broken, the broken yarn detector I501 sends an electric signal outwards; the second broken yarn detector 502 is arranged between the winch roller 301 and the spindle 4, the second broken yarn detector 502 is used for the plied yarns to pass through, the second broken yarn detector 502 is used for detecting whether the plied multi-strand yarns 9 are broken or not, and when the plied multi-strand yarns 9 are broken, the second broken yarn detector 502 sends an electric signal outwards.

The controller 6 is electrically connected to the first broken yarn detector 501 and the second broken yarn detector 502 and is used for receiving an electric signal sent by the first broken yarn detector 501 or the second broken yarn detector 502, the controller 6 is electrically connected to the capstan roller 301 and the spindle 4, when the controller 6 receives the electric signal sent by the first broken yarn detector 501 or the second broken yarn detector 502, the capstan roller 301 and the spindle 4 are simultaneously stopped by the controller 6, at the moment, the multi-strand yarn doubling and twisting mechanism stops working, and therefore the phenomenon that the number of strands of the multi-strand yarn 9 after twisting cannot reach the required number is avoided, namely the number of the yarns in the twisted strands cannot reach the required number. After the worker finishes processing the broken yarn, the controller 6 starts the winch roller 301 and the spindle 4, and the yarn multi-strand cabling mechanism starts to work normally.

Therefore, the first broken yarn detector 501, the capstan roller 301, the second broken yarn detector 502 and the spindle 4 are electrically connected to the controller 6, the controller 6 is used for controlling the closing of the doubling and twisting mechanism in a centralized mode, the doubling and twisting mechanism stops automatically when the yarn is broken, and the technical problem that the twisted yarn is easy to have strand missing is solved.
