Description

Technical Field

[0001] This utility model relates to the technical field of knitting machine accessories, specifically a high-strength knitting machine needle. Background Technology

[0002] Knitting machine needles are a major loop-forming component on knitting machines. They are made of steel wire or steel strip through mechanical processing. Their main function is to weave yarn into loops and connect these loops together to form knitted fabric.

[0003] The needles on some existing knitting machines are generally of average strength. They are prone to breakage when encountering complex working environments or after prolonged use, which affects the normal operation of the knitting machine and requires disassembly and re-threading, thus having certain limitations. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength knitting machine needle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength knitting machine needle, comprising a needle bar, wherein a needle hook is provided at the bottom end of the needle bar;

[0006] The bottom of the needle bar is provided with a set of recovery grooves corresponding to the position of the needle hook, and a set of needle tongues is provided in the recovery grooves.

[0007] Preferably, the inner side of the recycling tank is provided with a metal coating.

[0008] Preferably, the needle hook includes a base, an intermediate layer and an outer layer, wherein the intermediate layer is provided on the outside of the base, and the outer layer is provided on the outside of the intermediate layer.

[0009] Preferably, the outer layer has a thickness of 2-5 micrometers.

[0010] Preferably, the metal coating is a nano-metal coating, and it contains reinforcing ceramic microparticles.

[0011] Preferably, the metal coating is applied to the inside of the recycling tank via an electroplating process.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The needle hook is equipped with a needle bar, with a needle hook connected to the bottom of the needle bar. A collection groove is provided near the needle hook on the outer bottom of the needle bar, and a needle tongue is provided in the collection groove to prevent the yarn from falling off. The needle hook includes components such as a base, an intermediate layer, and an outer layer. The intermediate layer is located on the outside of the base, and the outer layer is connected to the outside of the intermediate layer. The cooperation of these components can significantly improve the strength and service life of the needle hook, making it suitable for different usage scenarios and yarns, and has strong practicality. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model;

[0015] Figure 2 This is a schematic diagram of the metal coating structure of this utility model;

[0016] Figure 3 This is a schematic diagram of the needle hook structure of this utility model.

[0017] In the diagram: needle bar-1, needle hook-2, recovery groove-11, needle tongue-12, metal coating-111, substrate-21, intermediate layer-22, outer layer-23. Detailed Implementation

[0018] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0019] Please see Figure 1-2 This utility model provides a high-strength knitting machine needle, including a needle bar 1, and a needle hook 2 at the bottom end of the needle bar 1;

[0020] A set of recovery grooves 11 is provided at the bottom of the needle bar 1 corresponding to the position of the needle hook 2. A set of needle tongues 12 is provided in the recovery grooves 11. A metal coating 111 is provided on the inner side of the recovery grooves 11. The metal coating 111 is a nano metal coating and contains reinforcing ceramic particles. The material is nano aluminum alloy and boron nitride particles. It is set on the inner side of the recovery grooves 11 by electroplating process. It has the advantages of low density and good corrosion resistance and is suitable for knitting machine parts that are sensitive to weight.

[0021] Please see Figure 3 This utility model provides a high-strength knitting machine needle. The needle hook 2 includes a base 21, an intermediate layer 22, and an outer layer 23. The base 21 is made of martensitic stainless steel, which has high hardness, toughness, and wear resistance, making it suitable for the needle hook 2 to work in complex stress environments. An intermediate layer 22 is provided on the outside of the base 21. The intermediate layer 22 is a tungsten carbide particle layer, which can significantly improve the overall strength of the needle hook 2 and enhance its wear resistance, effectively extending its service life.
