Description

Technical Field

[0001] This utility model relates to the field of nanofiber yarn production technology, and in particular to a nanofiber yarn spinning device. Background Technology

[0002] Nanofiber yarn is a textile material with unique properties and wide applications. It is typically composed of fibers with diameters in the nanometer range, exhibiting characteristics such as high specific surface area and high surface energy. These properties make nanofiber yarn excellent in terms of functionality, such as antibacterial, anti-mite, moisture-wicking, and breathable properties.

[0003] Nanofiber yarns can be manufactured using various processes, including electrospinning and melt spinning. Among these, electrospinning, which produces nanofibers with smaller diameters and larger surface areas, is one of the important methods for preparing nanofiber yarns.

[0004] Electrospinning equipment typically consists of several parts, including a fiber material feeding device, a fiber material pretreatment device, a spinning machine, and a yarn winding device. However, the winding components of current spinning equipment struggle to automatically adjust the winding tension of nanofiber yarns. Changes in winding tension after yarn production can easily lead to uneven winding and yarn breakage, significantly reducing the production quality of nanofiber yarns. Utility Model Content

A fixed frame 7 is fixedly connected to the top surface of the fixed frame 1, and a lifting mechanism is provided on the front of the fixed frame 1. The lifting mechanism consists of a fixed ring 8, a threaded rod 9, and a threaded sleeve 10. The fixed ring 8 is connected to the fixed frame 1. The fixed frame 1 is fixedly connected to the front, the threaded rod 9 is rotatably connected to the inner wall of the fixed ring 8, the threaded sleeve 10 is fixedly connected to the front of the limiting slider 4, and the inner wall of the threaded sleeve 10 is threadedly connected to the threaded rod 9, which is used to drive the adjusting roller 6 and the yarn to move up and down, so as to facilitate automatic adjustment of the yarn conveying tension. The fixed frame 7 is equipped with a drive assembly, which consists of a first servo motor 11, a drive wheel 12, a transmission belt 13 and a driven wheel 14. The first servo motor 11 is fixedly connected to the inner wall of the fixed frame 7, the inner wall of the drive wheel 12 is fixedly connected to the output end of the first servo motor 11, the transmission belt 13 meshes with the inner wall of the drive wheel 12, and the inner wall of the driven wheel 14 is fixedly connected to the surface of the threaded rod 9, and the inner wall of the driven wheel 14 meshes with the transmission belt 13, which is used to drive the lifting mechanism to rotate, so as to facilitate the conversion of rotational force into lifting force.

[0023] Specifically, the yarn guiding mechanism consists of a linear motor 15, a yarn guiding plate 16, and a yarn guiding hole 17. The linear motor 15 is fixedly connected to the top surface of the fixed frame 1, and the yarn guiding plate 16 is fixedly connected to the moving end of the linear motor 15. The yarn guiding hole 17 is opened through the left side of the yarn guiding plate 16 to drive the fiber yarn to swing longitudinally back and forth, thereby improving the uniformity of the fiber yarn winding.

[0024] Specifically, the winding assembly consists of a fixed plate 18, a winding roller 19, and a second servo motor 20. The fixed plate 18 is fixedly connected to the left side of the fixed frame 1, the winding roller 19 is rotatably connected to the inner wall of the fixed plate 18, and the second servo motor 20 is fixedly connected to the front of the fixed plate 18.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0026] In use: First, the nanofiber yarn to be wound is pulled along the lower part of the auxiliary roller 2, the upper part of the adjusting roller 6, and the inner wall of the guide hole 17 to the inner wall of the winding roller 19 and fixed. Then, the second servo motor 20 is started to drive the winding roller 19 to rotate along the inner wall of the fixed plate 18. At the same time, the linear motor 15 is started to drive the fiber yarn to swing longitudinally back and forth through the guide plate 16 and the guide hole 17, so that the fiber yarn can be wound evenly.

Through the threaded connection between the threaded rod 9 and the threaded sleeve 10, the limiting slider 4 is driven to slide up and down along the inner wall of the limiting groove 3. The movement of the limiting slider 4 drives the through-shaft tension sensor 5, the adjusting roller 6, and the fiber yarn to move up and down, so as to adjust the winding tension of the fiber yarn.

[0027] In summary, this nanofiber yarn spinning device draws the nanofiber yarn along the lower part of the auxiliary roller 2, the upper part of the adjusting roller 6, and the inner wall of the guide mechanism to the inner wall of the take-up assembly for fixation. Activating the take-up assembly and guide mechanism allows for uniform take-up of the fiber yarn.

Through the threaded connection of the lifting mechanism, the limit slider 4, the through-shaft tension sensor 5, the adjusting roller 6, and the fiber yarn can be moved up and down to adjust the take-up tension. This achieves the goal of automatically detecting and adjusting the tension during take-up of the nanofiber yarn, avoiding yarn breakage and uneven take-up caused by changes in the take-up tension, thus greatly reducing the quality problems in nanofiber yarn production and solving the problems mentioned in the background art.
