With the continuous development and improvement of the textile knowledge system and discipline system, especially the emergence of non-woven textile materials and three-dimensional composite weaving technologies, it is no longer just traditional hand spinning and weaving, but also includes non-woven fabric technology, modern three-dimensional weaving technology, modern electrostatic nano-netting technology and other production of clothing, industrial and decorative textiles. In the weaving production process, a drawing-in machine is needed to insert the yarn into the finished product, but when the drawing-in machine pulls the yarn from the coil, the yarn is easy to tangle and it is inconvenient to transport.

[0038] Working principle: When used, Figure 1 and Figure 6 As shown, the yarn on the yarn feeding roller 2 passes through the surface of the guide roller 6, and under the guidance of the fixing ring 7 and the groove 8, the yarn is evenly stuck in the groove 8 for transportation, as shown in FIG. Figure 5 As shown, when the guide roller 6 guides the yarn, the active rod 43 and the limit ring 44 are driven to move downward in the active groove 42 under the action of tension, and the reset spring 45 is squeezed. Under the elastic action of the reset spring 45, the yarn is elastically tightened to prevent the yarn from breaking and to avoid the yarn from being loose and scattered during the conveying process. When the guiding angle of the guide roller 6 needs to be adjusted, as shown in FIG. Figure 2 and Figure 4 As shown, when the guide roller 6 is rotated clockwise, the ratchet 303 is driven to rotate through the connecting rod 41, and the connecting plate 305 is pushed to rotate outward through the limit block 310, so that the first telescopic rod 306 is contracted, and the first spring 307 is squeezed and deformed. After adjustment, under the rebound action of the first spring 307, the limit block 310 is driven to insert into the gap of the ratchet 303.
