Description

Technical Field

[0001] The invention belongs to the technical field of yarn guide manufacturing, and in particular relates to a preparation method of a highly durable textile yarn guide and the yarn guide. Background Art

[0002] The textile industry refers to the industry that uses textile equipment and technology to process fiber materials and manufacture textiles. The high-wear-resistant wire guide used in the textile industry is a device used to guide the fiber material to the correct position during the textile process, ensure that the fiber material passes through the processing equipment smoothly, and maintain its stability and wear resistance. The high-wear-resistant wire guide in the textile industry is usually used in looms, rope machines, braiding machines and other equipment to guide fiber materials and maintain the correct position and movement trajectory of fiber materials during the processing process to ensure the production quality and process effect of textiles. Since the fiber materials in the textile industry often have high strength and large friction, the high-wear-resistant wire guide needs to have high wear resistance and stability to maintain its long service life and reliability. Traditional metal wire guides have poor wear resistance and therefore cannot meet the requirements of modern textile machinery. Compared with metal materials, ceramic materials have higher hardness and wear resistance, as well as better corrosion resistance and chemical stability. Therefore, ceramic wire guides with excellent comprehensive performance are increasingly used in the field of textile machinery. Existing processes have limited surface treatment and coating technologies for wire guides, and the wear-resistant layer formed on the surface is not dense and uniform enough, resulting in the inability to effectively improve the wear resistance and service life of the product. Summary of the invention

[0003] Purpose of the invention: The purpose of the present invention is to provide a method for preparing a highly durable textile yarn guide and a yarn guide to solve the above-mentioned technical problems.

[0004] Technical solution: In order to achieve the above-mentioned purpose, the present invention provides a method for preparing a highly durable textile yarn guide, comprising the following steps: S1, material selection: select high-performance wear-resistant metal as the base material; S2, forming processing: using cutting tools (such as laser cutting, mechanical cutting tools, etc.) to cut the raw materials into a rough shape, and then further shaping the basic shape through forging or stamping; S3, finishing: Use turning, milling, grinding and other mechanical processing methods to perform precision processing on the parts to ensure that the dimensional accuracy and surface roughness of each part meet the design requirements; S4: sandblasting: the rotating guide wheel is sandblasted; S5, coating treatment: coating the surface of the rotating guide wheel with a wear-resistant ceramic material; S6, annealing treatment: annealing treatment is performed on the rotating guide wheel coated with the wear-resistant ceramic layer; S7, surface treatment: polish the rotating guide wheel with diamonds, and polish the contact part between the rotating guide wheel and the rotating shaft; S8, assembly and debugging: Assemble the processed rotating guide wheel and the rotating shaft. After assembly, check the rotation flexibility of the wire guide wheel.

[0005] Furthermore, the wear-resistant metal material in step S1 is alloy steel, which has excellent properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, and high temperature resistance.

[0006] Furthermore, the step S3 specifically includes: using a CNC machine tool to process the wire guide groove and the shaft hole on the rotating shaft and the rotating guide wheel.

[0007] Furthermore, in the step S4, the sandblasting is performed by using a dedicated sandblasting device to spray fine abrasive particles onto the surface of the wire guide, and impurities and oxides on the surface are removed by high-speed spraying to ensure good adhesion of the wear-resistant ceramic layer.

[0008] Furthermore, the coating treatment heats and melts the wear-resistant ceramic material, uses a high-speed airflow to atomize the molten ceramic material into extremely fine particles, and sprays them onto the surface of the workpiece at high speed to form a coating. The wear-resistant ceramic coating formed by this process is more uniform, finer, and denser.

[0009] Furthermore, the wear-resistant ceramic material is an alumina ceramic material. Alumina wear-resistant ceramic has high hardness and excellent wear resistance.

[0010] Furthermore, in step S7, the annealing treatment is to heat the rotating guide wheel covered with the wear-resistant ceramic layer in an inert atmosphere, the temperature of which is lower than the temperature of the alumina ceramic, and then keep it warm for a period of time, and slowly cool it to room temperature after the insulation is completed. Through the annealing treatment, the internal stress of the ceramic can be effectively eliminated and the overall stability of the ceramic can be improved; the annealing treatment can make the grains of the alumina ceramic more refined and the grain boundaries more dense, thereby improving the density and mechanical strength of the ceramic. The improvement of density and mechanical strength can not only make the ceramic more stable when subjected to external forces, but also improve its wear resistance and service life; annealing in an inert atmosphere can effectively prevent the alumina ceramic from easily reacting with oxygen at high temperatures; the ceramic is slowly cooled after the annealing is completed to avoid cracks caused by excessive temperature differences. Slow cooling can fully release the stress inside the ceramic and further improve its stability and wear resistance.

[0011] Furthermore, in step S8, the polishing process is to grind the wear-resistant ceramic layer with diamond paste to achieve a higher surface finish; at the same time, the shaft hole and the rotating shaft are polished to reduce friction.

[0012] A highly durable textile yarn guide comprises a rotating guide wheel and a rotating shaft, wherein an annular yarn guide groove is provided on the side of the rotating guide wheel, an axial hole is provided along the center line of the bottom of the rotating guide wheel, a bearing is provided in the axial hole, and the rotating shaft is provided in the axial hole and cooperates with the bearing; and a wear-resistant ceramic layer is provided on the surface of the rotating guide wheel.

[0013] It can be seen from the above technical solution that the present invention has the following beneficial effects: 1. The present invention provides a method for preparing a highly durable textile yarn guide and a yarn guide, which uses a coating treatment technology of atomizing and spraying ceramic materials, releases the internal stress of the ceramic through annealing, and polishes the ceramic layer after annealing, so that the wear-resistant ceramic layer is more uniform and dense, thereby improving its stability and wear resistance.

[0014] 2. Through molding, finishing and other processes, the size and shape can be accurately controlled to improve the accuracy of the wire guide. Sand blasting can enhance the adhesion of the coating and increase its service life. The contact area between the shaft and the rotating guide wheel can be polished to reduce friction, further improving the use effect and service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0018] like Figure 1 As shown, a method for preparing a highly durable textile yarn guide comprises the following steps: S1, material selection: select high-performance wear-resistant metal as the base material; S2, forming processing: using cutting tools such as laser cutting, mechanical cutting tools, etc. to cut the raw materials into a rough shape, and then further shaping the basic shape through forging or stamping; S3, finishing: Use turning, milling, grinding and other mechanical processing methods to perform precision processing on the parts to ensure that the dimensional accuracy and surface roughness of each part meet the design requirements; S4: sandblasting: performing sandblasting on the rotating guide wheel 1; S5, coating treatment: coating the surface of the rotating guide wheel 1 with a wear-resistant ceramic material; S6, annealing treatment: annealing treatment is performed on the rotating guide wheel coated with the wear-resistant ceramic layer; S7, surface treatment: polishing the rotating guide wheel 1 with diamonds, and polishing the contact portion between the rotating guide wheel 1 and the rotating shaft 2; S8, assembly and debugging: Assemble the processed rotating guide wheel 1 and the rotating shaft 2. After the assembly is completed, check the rotation flexibility of the wire guide wheel.

[0019] Wherein, the wear-resistant metal material in step S1 is alloy steel. In addition, other materials such as high manganese steel, wear-resistant chromium cast iron and the like can also be selected as needed.

[0020] Specifically, the step S3 specifically includes: using a CNC machine tool to process the rotating shaft 2 and the wire guide groove 11 and the shaft hole on the rotating guide wheel 1.

[0021] Specifically, in the step S4, the sandblasting is performed by using a dedicated sandblasting device to spray fine abrasive particles on the surface of the wire guide, and impurities and oxides on the surface are removed by high-speed spraying to ensure good adhesion of the wear-resistant ceramic layer.

[0022] In an optional embodiment, the coating treatment heats and melts the wear-resistant ceramic material, uses a high-speed airflow to atomize the molten ceramic material into extremely fine particles, and sprays them onto the surface of the workpiece at a high speed to form a coating.

[0023] Specifically, the wear-resistant ceramic material is an alumina ceramic material.

[0024] In addition, in step S7, the annealing treatment is to heat the rotating guide wheel covered with the wear-resistant ceramic layer in an inert atmosphere, the temperature of which is lower than the temperature of the alumina ceramic, and then keep the temperature for a period of time, and then slowly cool to room temperature after the end of the heat preservation. The inert gas can be hydrogen, carbon monoxide, etc.

[0025] In addition, in step S8, the polishing process is to grind the wear-resistant ceramic layer with diamond paste to achieve a higher surface finish; at the same time, the shaft hole and the rotating shaft 2 are polished to reduce friction. In addition, as an alternative, Al2O3 micropowder less than 1μm can be used for grinding, which can gradually improve the surface finish. Another preferred solution: using a high-energy laser beam to locally heat and melt the surface of the alumina ceramic, thereby achieving surface smoothing and polishing.
