Description

Technical Field

[0001] The utility model relates to the technical field of yarn guides, in particular to a yarn guide rack for yarn threading. Background Art

[0002] Yarn is a textile product made of various textile fibers and processed into a certain fineness. It is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short-staple yarn, continuous filament, etc. There are many ways to express the fineness of yarn, such as number, metric count, imperial count, denier, etc. (see count); the twist of yarn is expressed by the number of twists per meter or per inch. Wool yarn and wool are generally used to weave wool sweaters, wool trousers, wool vests, scarves, hats and gloves, and to knit various spring and autumn clothing items. In addition to keeping warm, they also have decorative functions.

[0003] After searching, it was found that in a yarn guide frame structure that facilitates yarn threading and has patent publication number CN217577799U, it is proposed that "by providing a yarn guide mechanism, the yarn is effectively introduced into the device through the yarn guide roller, and sequentially passes through the yarn guide hole, between the upper and lower yarn pressure discs, and the yarn threading hole to complete the yarn guiding. At the same time, the upper and lower yarn pressure discs can float up and down under the action of the tower spring to ensure the tension of the guide yarn and limit and press it to avoid the yarn from being entangled due to yarn relaxation during shutdown, thereby improving its use efficiency and enhancing its usability."

[0004] However, the above solution still has certain shortcomings in actual use. In this technical solution, the yarn is guided by a yarn pressing member, but the yarn pressing member uses an upper yarn pressing disc and a lower yarn pressing disc to process the yarn under the action of a tower spring. This processing method is a passive yarn guiding method and cannot actively adjust the tension of the yarn, thereby reducing the practicality of the yarn guide frame. Utility Model Content
