[0002] Textile machine needles, also known as sewing needles or machine needles, are key accessories for textile machinery. Depending on their application and purpose, textile machine needles come in various types. For example, in sewing machines, the type and specifications of the needle are determined by the sewing machine model and the nature of the fabric being sewn. In knitting machines, especially computerized knitting machines, specific types of needles, such as latch needles, may be used.

[0003] In the textile industry, textile machine needles are one of the key components, and their performance directly affects the quality of textile products and production efficiency. Traditional textile machine needles often suffer from problems such as rapid wear, easy deformation, and easy breakage during use. This not only increases production costs but also reduces production efficiency and product quality. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-4A high-performance textile machine needle includes a needle bar assembly 1 and a needle tip assembly 2. The needle tip assembly 2 is fixedly installed at the end of the needle bar assembly 1. The needle bar assembly 1 has a needle eye 31, and the entrance of the needle eye 31 is chamfered 33. The chamfer 33 design reduces friction with the yarn while ensuring smooth yarn passage. Both the chamfer 33 and the inner wall of the needle eye 31 are fixedly coated with a wear-resistant coating 32. The wear-resistant coating 32 enhances the wear resistance of the needle eye 31, extends the service life of the textile machine needle, reduces the replacement frequency due to wear, and thus improves the efficiency and stability of textile production. The needle bar assembly 1 includes a core layer 11, which provides internal strength to the needle, ensuring it does not break during high-speed operation. A hardening layer 12 is fixedly installed on layer 11. The hardening layer 12 provides strength and rigidity to the needle bar, ensuring that the needle does not bend or break under high-speed movement. A reinforcing layer 13 is fixedly installed on the hardening layer 12. The reinforcing layer 13 further enhances the strength and toughness of the needle bar, especially ensuring the stability of the needle bar when subjected to large impacts or tensions. A reinforcing layer 14 is fixedly installed on the reinforcing layer 13. The reinforcing layer 14 enhances the mechanical strength of the entire needle, especially against impacts, vibrations, and overloads that may occur during high-speed operation, preventing breakage or deformation. A smoothing layer 15 is fixedly installed on the reinforcing layer 14. The smoothing layer 15 ensures that the needle surface is smooth and flawless, reducing friction with yarn or fabric and lowering the probability of yarn breakage or damage.

[0020] In detail, the needle tip assembly 2 includes a needle tip body 21, which is conical in shape. The conical needle tip body 21 is designed to reduce friction with the fabric and ensure the sharpness and durability of the needle tip. The needle tip body 21 is fixedly installed at the end of the needle bar assembly 1.

[0021] Furthermore, a needle tip coating 22 is fixedly installed on the needle tip body 21. The needle tip coating 22 is made of titanium alloy. By setting the needle tip coating 22, the wear resistance, corrosion resistance and high temperature resistance of the needle tip are enhanced, and the service life of the needle is extended.

[0022] Furthermore, the wear-resistant coating 32 is made of diamond coating, a coating material with extremely high hardness, excellent wear resistance, and an extremely low coefficient of friction. It significantly improves the wear resistance, hardness, and service life of tools and parts, and is widely used in cutting tools, automotive parts, aerospace, and other fields, demonstrating superior performance and broad application prospects. By incorporating the wear-resistant coating 32, the wear resistance of the needle eye 31 is enhanced, extending the service life of textile machine needles and reducing the frequency of replacement due to wear, thereby improving the efficiency and stability of textile production.

[0023] More specifically, the core layer 11 is made of stainless steel, an alloy steel with excellent corrosion resistance, whose main components are iron, chromium, nickel, and other elements. It has good resistance to weak corrosive media such as air, steam, and water, and is also high in strength, high in temperature, easy to process, and has good weldability. It is widely used in tableware, household appliances, machinery manufacturing, and architectural decoration. The core layer 11 provides internal strength to the needle, ensuring it does not break during high-speed operation.

[0024] In summary, the hardened layer 12 is made of high-speed steel, which has high hardness, high wear resistance and high heat resistance. It is mainly used to manufacture complex thin-bladed and impact-resistant metal cutting tools, and can also be used to manufacture high-temperature bearings and cold extrusion dies. It is an indispensable material in the manufacturing industry. The hardened layer 12 is used to provide strength and rigidity to the needle bar, ensuring that the needle does not bend or break under high-speed movement. The reinforcing layer 13 is made of carbon fiber. The reinforcing layer 13 is used to further enhance the strength and toughness of the needle bar, especially when subjected to large impacts or tensile forces, to ensure the stability of the needle bar.

[0025] Finally, the reinforcing layer 14 enhances the mechanical strength of the entire needle, especially against impacts, vibrations, and overloads that may occur during high-speed operation, preventing breakage or deformation. The smoothing layer 15 is made of nickel-plated coating, ensuring a smooth and flawless needle surface, reducing friction with yarn or fabric, and lowering the probability of yarn breakage or damage.

[0026] Working principle: During operation, a core layer 11 provides internal strength to the needle, ensuring it does not break during high-speed operation. A hardening layer 12 provides strength and rigidity to the needle bar, preventing bending or breakage under high-speed motion. A reinforcing layer 13 further enhances the strength and toughness of the needle bar, ensuring its stability, especially under significant impact or tension. A reinforcing layer 14 strengthens the overall mechanical strength of the needle, particularly against impacts, vibrations, and overloads that may occur during high-speed operation, preventing breakage or deformation. A smoothing layer 15 ensures a smooth and flawless needle surface, reducing friction with yarn or fabric and lowering the likelihood of yarn breakage or damage.

[0027] The wear-resistant coating 32, combined with the chamfer 33, enhances the wear resistance of the needle eye 31, extends the service life of the textile machine needle, reduces the replacement frequency caused by wear, and thus improves the efficiency and stability of textile production. The needle tip coating 22 enhances the wear resistance, corrosion resistance and high temperature resistance of the needle tip, and extends the service life of the needle.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
