[0027] The threading mechanism 5 includes a hook frame 501, which is fixedly connected to the frame 1. A mounting frame 502 is provided on the hook frame 501. A yarn clamping frame 503 is horizontally slidably connected above the mounting frame 502. A yarn clamp 504 is fixedly connected to the yarn clamping frame 503. A crochet hook frame 505 is slidably connected to one side of the mounting frame 502. A crochet hook body 506 is fixedly connected to the crochet hook frame 505.

Through the arrangement of the trolley guide rail and the trolley body, the sorted wool yarn can be spread flat on the trolley body, and one end of the sorted wool yarn can be passed through the threading plate on the trolley body, which is convenient for subsequent manual pushing of the trolley mechanism 3 to push the sorted wool yarn to the side of the weaving machine, and use the sorted wool yarn to perform weaving operations on the wool yarn.

[0032] A wire pulling cylinder 513 is fixedly connected to the vertical plate 5023, and the piston rod of the wire pulling cylinder 513 is fixedly connected to the yarn clamping frame 503. Through the arrangement of the wire pulling cylinder 513, after the sorted wool yarn is fixed on the yarn clamping device 504, the yarn clamping device 504 is pulled to drive the wool yarn to slide horizontally, so that the wool yarn can be hung on the crochet hook body 506.

[0033] A thread break detector 507 is fixedly connected to one side of the yarn clamping frame 503 above the yarn clamping device 504. Through the thread break detector 507, when the thread pulling mechanism 4 pulls the yarn for sorting, if it is detected that the thread pulling mechanism 4 has not pulled the yarn on the pay-off mechanism, the thread pulling mechanism 4 will be restarted to re-pull the yarn on the pay-off mechanism. When the thread break detector 507 fails to detect the yarn twice, the entire device will be shut down to check whether there is any abnormality in the thread pulling mechanism 4 and the pay-off mechanism.

[0034] An adjustment frame 514 is rotatably connected to the side of the vertical plate 5022 away from the horizontal plate 5021.
