Description

Technical Field

[0001] The utility model relates to the technical field of high-strength fiber production, in particular to a device for improving the spinning conditions of high-strength nylon fiber production. Background Art

[0002] High-strength nylon fibers possess excellent strength properties and can withstand significant tension and impact. Generally, high-strength nylon fibers utilize multiple high-draw ratios, resulting in fiber breaking strengths of 6-9 CN / dtex, which is 2-5 CN / dtex higher than the breaking strength of conventional fibers. Therefore, fabrics woven from high-strength fibers exhibit improved wear resistance and are able to maintain stable performance over the long term, making them highly sought after in the textile and industrial sectors. With technological advancements and the continued expansion of the market, their application prospects will become even broader. In the apparel sector, they can be applied to textile and apparel products such as underwear, shirts, stockings, outdoor sportswear, and equipment. In the industrial sector, they can be used to make industrial ropes, cables, and rope nets. Their high strength, wear resistance, and good elasticity make these products more durable and comfortable.

[0003] The multi-pass high-draw ratio process setting can achieve higher breaking strength in the fiber. However, statistical data shows that the production stability of high-strength nylon fiber is significantly worse than that of conventional nylon fiber during production, which is mainly manifested in a higher number of end-breaks. Nearly 80% of the end-breaks are caused by entanglement on the drafting roller GR1. Before the end-break, the tow shakes violently on the drafting roller GR1, and there is unstable adhesion between the yarns. Therefore, we designed a device that can solve the problems of end-breaks caused by entanglement on the drafting roller GR1 and the excessive shaking of the tow on the drafting roller GR1 during production. It improves the uneven tension of the tow entering the godet, thereby reducing the adhesion of the tow caused by tension fluctuations or insufficient tension at GR1, achieving tow stability, and thus improving the production and spinning conditions of high-strength fibers. Utility Model Content

[0004] The utility model aims to provide a device for improving the spinning conditions of high-strength nylon fibers, which can adjust the tension of the filament bundles evenly when the filament bundles enter the godet rollers.

[0005] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0006] The utility model proposes a device for improving the spinning conditions of high-strength nylon fiber production, comprising a base plate and a pre-network device arranged on the base plate for the entry of yarn bundles, wherein a first yarn bundle adjustment component, a yarn bundle guide rod component, a second yarn bundle adjustment component, an SR1 roller and a GR1 roller are sequentially arranged on the base plate below the pre-network device from top to bottom.

[0007] Furthermore, the first tow adjustment assembly, the tow guide rod assembly, and the second tow adjustment assembly each include an adjustment rod, each of which is correspondingly arranged on a rotating support, and each of the adjustment rods is fixed to the base plate via a connecting base.

[0008] Furthermore, a wire guide hook bracket is provided on each of the rotating supports of the first wire bundle adjusting assembly and the second wire bundle adjusting assembly, and a plurality of wire guide hooks are provided on the wire guide hook bracket.

[0009] Furthermore, a wire guide rod is provided on the rotating support of the wire guide rod assembly.

[0010] Furthermore, a scale is provided on the adjusting rod.

[0011] Furthermore, the distance between adjacent adjustment rods is 8 to 12 cm.

[0012] Furthermore, the SR1 roller is located to the upper right of the GR1 roller.

[0013] The beneficial effects of this utility model include: increasing the tension at GR1 by precisely adjusting the relative positions of the three-layer adjustment brackets, while simultaneously reducing the tension deviation of each yarn during the tension increase process. The addition of scales on the adjustment rod allows for tension control of the same variety, enabling process replication and simplifying tension adjustment, thus increasing the practicality and simplicity of the device.
