Description

Technical Field

[0001] The present application relates to the technical field of textile machinery and equipment, and in particular to a yarn winding device with adjustable tension. Background Art

[0002] Yarn is a kind of textile product, which is processed from various textile fibers into products with a certain fineness and is used for weaving, making ropes, making threads, knitting, embroidery, etc. It is divided into short fiber yarns, continuous filaments, etc. There are various ways to represent the fineness of yarns, such as count, metric count, English count, denier, etc. The twist of yarn is expressed by the number of twists per meter or per inch. In the use of textile machinery, it is usually necessary to process yarns, and winding the yarns is the most common, which can make the yarns neatly wound on a hollow rod, facilitating later use and preventing the yarns from being often wound together, thereby improving the use efficiency of the yarns.

[0003] During the production process of yarns, a yarn winding device with adjustable tension is required. The Chinese utility model patent with the publication number CN220617949U discloses a yarn winding device for textile machinery that can keep the tension of yarns. It relates to the technical field of textile machinery and includes a workbench and an installation box installed on the top of the workbench. A driving roller for conveying yarns is rotatably arranged in the workbench. This utility model uses a driving gear to drive a driving rack meshed on one side of the driving gear to drive a fixed seat to move vertically downward. At this time, a tension adjusting roller rotatably connected to the fixed seat can move vertically downward to press the yarn to increase the tension of the yarn.

[0004] In the process of implementing the present application, there are at least the following problems in this technology. The yarn winding device for textile machinery that can keep the tension of yarns adjusts the tension of the yarn by adjusting the height of the tension adjusting roller. However, this adjustment method causes the force application point of the subsequent wound yarn to continuously increase in tension during the winding process, easily resulting in deformation of the yarn, and it is impossible to flexibly adjust the yarn tension according to actual needs, seriously affecting the quality of yarn winding. Therefore, a yarn winding device with adjustable tension is proposed to solve the problems raised above. Summary of the Utility Model
