Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a yarn concave-convex raising device. Background Art

[0002] Yarn is a kind of textile, which is processed into a certain fineness from various textile fibers and used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short-staple yarn, continuous filament, etc. Wool yarn and wool thread are generally used to weave wool sweaters, wool trousers, wool vests, scarves, hats and gloves, and weave various spring and autumn clothing items. In addition to keeping warm, they also have decorative effects. In order to avoid the woven fabric being monotonous and dull, the yarn often needs to be raised to improve the feel and warmth retention.

[0003] Publication number: CN 209923541 U's patent discloses a yarn raising device, which includes a mounting plate, on which a rotatable rotating rod is inserted, and a rotating head is fixedly installed at the lower end of the rotating rod in the length direction, and the central rotating shaft of the rotating head coincides with the central axis of the rotating rod. The device avoids the disadvantage of too long raising of the yarn by the raising machine, and is not only suitable for ordinary flat yarn, but also for various chemical fiber filaments, twisted yarns, loop yarns, corrugated yarns, etc. It has a wide range of applications and can replace various raising machines. However, the device has the problem that after the yarn to be raised passes through the outlet and the guide wire outlet, the yarn is driven to rotate by the friction wheel, the flat belt pulley and other structures, and then the yarn is rubbed with the conical grinding wheel for raising. The installed perforations make it difficult to quickly install the yarn in the device, and the method of using the rotation of the yarn and the friction of the conical grinding wheel can only raise all positions of the yarn, that is, the raising position of the yarn cannot be controlled according to demand. For this reason, a yarn concave-convex raising device is proposed to solve the problem that the existing yarn raising device is difficult to control the raising position according to demand.
