[0024] In this embodiment, the U-shaped cover 1 serves as the main structure of the entire device. The servo motor 3 drives the lifting plate 6 to perform lifting movement inside the U-shaped cover 1 by accurately controlling the rotation of the screw 2, thereby controlling the multiple first guide wheels 9 and the multiple second guide wheels 15 to approach or move away from each other, so as to facilitate the staff to place the yarn. The lifting plate 6 is guided and limited by multiple limit rods 4 to ensure the stable lifting of the lifting plate 6 driven by the screw 2.

[0025] In summary, the wire breakage detection device of the wire doubling machine of this patent realizes efficient and accurate wire breakage detection of multiple yarns through its unique design and component configuration, and at the same time takes into account the guidance, positioning and dust reduction requirements during the yarn processing process, providing an advanced yarn detection equipment for the textile industry.
