Length-adjustable yarn bobbin

Abstract

The invention relates to the technical field of textile, in particular to a length-adjustable yarn bobbin which comprises a yarn bobbin body. The yarn bobbin yarn is in the shape of a hollow cylinder, an upper retaining plate and a lower retaining plate are arranged at two ends of the yarn bobbin body respectively, the yarn bobbin body is of a structure of three layers including an upper portion, a middle portion and a lower portion from top to bottom, the upper portion comprises the upper retaining plate and an upper bobbin body, the upper retaining plate is fixed at the top end of the upper bobbin body, an internal thread is arranged at the tail end of the side wall of the upper bobbin body, the lower portion comprises the lower retaining plate and a lower bobbin body, the lower retaining plate is fixed at the tail end of the lower bobbin body, an external thread is arranged at the top end of the side wall of the lower bobbin body, the middle portion comprises two through bobbins, the inner diameter of a first through bobbin is equal to the outer diameter of each of the upper bobbin body and the lower bobbin body, an internal thread and an external thread are arranged at two ends of the first through bobbin respectively, and the outer diameter of a second through bobbin is equal to that of each of the upper retaining plate and the lower retaining plate. After adopting the above structure, requirements on diverse and efficient product are met, and normal and efficient running of production is guaranteed.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a length-adjustable yarn drum. Background technique [0002] In textile production, fabrics are woven with yarn, and the yarn is usually wound on the outer wall of the yarn drum. During use, the yarn drum rotates at high speed with the positioning column as the center. With the improvement of people's living standards, the requirements for textile products are getting higher and higher, both in terms of diversity and product quality. In order to meet the requirements of the market, [0003] Invention CN 202808079 U discloses a yarn bobbin, which divides the bobbin body into three parts through the upper and lower spacers left on the bobbin body, and wraps the yarns of three colors in the spacers respectively. On the barrel of the board, the simultaneous use of three colors of yarn is realized. However, due to the lack of structural design in the prior art, the barrel is only ...

Problems solved by technology

However, due to the lack of structural design in the prior art, the barrel is only limited to three-color yarns, which cannot meet larger-scale and more diverse uses, and the practicability is limited.
