[0027] When in use, the thread-adjusting transmission device is first fixedly connected to the frame of the seamless underwear production equipment through the mounting seat 25, and then the yarn is passed through the yarn guide through hole of the yarn guide mechanism 4 and the yarn feeding through hole 11 of the yarn feeding rod 2 from back to front in sequence, and the front end of the yarn is fixedly connected to the yarn feeding mechanism, thereby completing the installation of the thread-adjusting transmission device; the yarn guide mechanism 4 is then manually adjusted, and after the manual adjustment is completed, the sliders in different tracks 6 are driven by the driving mechanism 3 to move toward or in opposite directions along the track 6, thereby controlling the two yarn feeding rods 2 to move toward or in opposite directions, thereby achieving precise speed control and position adjustment, so as to ensure the stability and efficiency of the yarn changing process, and facilitate different hooks of the seamless underwear equipment to hook up the yarn; specifically The bottom end of the first slider 8 and the bottom end of the second slider 9 are connected to the second connecting rod 12 and the rack 13 respectively, and the second connecting rod 12 and the rack 13 are formed in one piece. After starting the motor 14, the motor 14 drives the two racks 13 to move toward or in reverse through the gear 15 at its output end, thereby making the first slider 8 and the second slider 9 in one track 6 move toward or in reverse with the first slider 8 and the second slider 9 in the other track 6. Since the top end of the first slider 8 is connected to the yarn feeding rod 2 through the connecting block 10, the two yarn feeding rods 2 can move toward or in reverse, thereby realizing precise speed control and position adjustment, which is convenient for different hooks of the seamless underwear equipment to hook up the yarn passing through the yarn feeding rod 2.

The relative positions of the yarn guiding rod sleeves 16 and the yarn guiding rods 17 in the yarn guiding mechanism 4 can be adjusted by the bolts 22, so that it can scrape and remove dust for yarns of different thicknesses; specifically, by rotating the bolts 22 to change the length of the bolts 22 penetrating the mounting plate 1, and then changing the horizontal height of the connecting seat 20, when the horizontal height of the connecting seat 20 changes, it will drive the fourth connecting rod 19 to move downward or upward. When the fourth connecting rod 19 moves downward, the angle between the two fourth connecting rods 19 changes. At this time, the two yarn guiding rods 17 slide outward in the two yarn guiding rod sleeves 16, thereby adjusting the size of the channel formed by the staggered first yarn guiding through hole 23 and the second yarn guiding through hole 24, and then the yarn can be passed through the channel; by changing the size of the channel, it can fully contact with yarns of different thicknesses, so that dust and impurities on the surface of the yarn passing through the channel can be scraped off.
