after the knotting knife group 10 is closed, the second swing pin 32 slides in the closing knife holding section 39, and according to different yarn types, in the whole set process, the length of the closing knife holding section 39 can be adjusted correspondingly, so that the knotting knife group 10 clamps the tail yarn to move until the yarn sleeve is pulled tightly, and after the yarn sleeve is pulled tightly, the second swing pin 32 slides to the opening knife holding section 41 along the opening knife inclined plane section 40, so that the second swing rod 24 swings, the second toggle foot 30 drives the switch knife control plate 18 to slide reversely, the switch knife control ring 21 drives the main yarn clamping plate 13 and the main yarn shearing knife 14 to slide reversely through the switch knife control ring clamping groove 22, so that the knotting knife group 10 is opened, and the tail yarn is separated from the knotting knife group 10 to complete knotting, as shown in fig. 30.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
