Description

Technical Field

[0002] Traditional wrapped yarns generally use spandex as the yarn core, and other non-elastic fibers are wrapped around the surface of the yarn core in a spiral coil shape with a fixed pitch to form functional yarns with an elastic structure. However, these yarns have a heavy gram weight, and clothes woven with these yarns are also heavy, which makes people feel uncomfortable when wearing them on their bodies.

[0003] Cashmere is a thin layer of fine wool that grows on the outer skin of goats and hides at the root of their coarse hair. Cashmere fibers have irregular, sparse and deep curls, strong elongation and excellent moisture absorption. They are thin, light, soft, smooth and warm. Cashmere fibers are moderately strong, elastic and have a natural soft color.

The first rotating groove 503 and the second rotating groove 504 form a rotating hole. The two unwinding members 54 each include a rotating rod 541 and a bobbin 542 that are detachably connected. The rotating rod 541 is plugged into the plug connector 521 and the rotating hole, and the rotating rod 541 of the other unwinding member 54 is plugged into the rotating head 56 and the rotating hole; the connecting member 53 is rotatably connected to the first rotating hole, and the connecting member 53 includes a coaxial first limiting tube 531, a guide column 532 and a second limiting tube 533, and the two ends of the guide column 532 extend into the first limiting tube 531 and the second limiting tube 533 respectively, and the first limiting tube 531 and the second limiting tube 533 are both provided with limiting plates 534. A spring 535 is provided between the end of the limiting plate 534 and the guide column 532, the first limiting tube 531 is plugged into the rotating rod 541 of one unwinding member 54, the second limiting tube 533 is plugged into the rotating rod 541 of another unwinding member 54, the rotating rod 541 is composed of a coaxial rod body and a tube body, the side wall of the tube body is provided with a positioning groove 506, the length direction of the positioning groove 506 is the same as the axial direction of the rod body, and a positioning strip 57 plugged into the positioning groove 506 is provided on the inner wall of the bobbin 542.

[0058] By removing the clamping plate 552, the rotating hole is opened, and then the connecting member 53 is removed from the rotating hole, and finally the unwinding member 54 is taken out from the first accommodating space 501 and the second space, the yarn loading and unloading can be replaced;

[0059] When the unwinding member 54 is placed in the first accommodating space 501, the two ends of the rotating rod 541 of the unwinding member 54 are respectively plugged into the plug connector 521 and the first position limiting tube 531; when the unwinding member 54 is placed in the second accommodating space 502, the two ends of the rotating rod 541 of the unwinding member 54 are respectively plugged into the second position limiting tube 533 and the rotating head 56; a plurality of accommodating members may be provided on the mounting frame 51 between the first accommodating space 501 and the second accommodating space 502, and the plurality of accommodating spaces may be connected by an intermediate platform 55, and the unwinding members 54 placed in the accommodating spaces may be connected to each other by connecting members 53; a plurality of unwinding members 54 may be synchronously rotated by a motor 52, and may be disassembled and installed on the mounting frame 51 by connecting members 53 and the intermediate platform 55;

[0062] like Figure 2 and Figure 3 As shown, the tension adjustment mechanism 2 includes tension adjustment components corresponding to the two groups of unwinding mechanisms 5, and the tension adjustment components include two tension members 21 corresponding to the two unwinding members 54 one by one.
