Description

Technical Field

[0001] This utility model relates to the field of knitting machine components, and in particular to an improved knitting needle for a knitting machine. Background Technology

[0002] A coarse knitting machine is a type of knitting machinery primarily used for knitting fabrics with a coarse gauge. Its working principle is based on the fundamental mechanism of a flat knitting machine, where the needles, driven by a cam mechanism, move in a regular up-and-down motion within the needle grooves of the needle plate. Through the coordinated action of the needle hooks and latches, the yarn is knitted into fabric. In this process, the yarn sequentially undergoes stages such as padding, carrying, closing, looping, loop release, and loop formation, ultimately forming the knitted fabric.

[0003] In the actual use of coarse knitting machines, the continuous wear of the knitting needles directly affects their service life. Severely worn needles may fail to maintain their original precision and shape, leading to decreased knitting efficiency and compromised fabric quality. More seriously, excessively worn needles may suddenly spring out during knitting, which not only interrupts the production process but also poses a safety threat to operators. Spring-out needles are particularly prone to causing injury on high-speed knitting machines, significantly increasing the risk. Utility Model Content

[0004] The main objective of this invention is to provide an improved knitting needle for a knitting machine, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An improved needle for a knitting machine includes a needle body shell; an inner needle body is provided inside the needle body shell, and the inner needle body is fixed to the needle body shell by a sleeve and bolts;

[0007] The inner needle body includes an inner shell, a lateral mounting groove, a needle body, and a needle head. The side wall of the inner shell has multiple lateral mounting grooves. The needle body is installed in the lateral mounting grooves, and the needle head is installed at the lower end of the needle body. The lower end of the inner shell is provided with a fixing head. The fixing head and the inner shell are provided with a second ring sleeve and a first ring sleeve. The first ring sleeve and the second ring sleeve enable the needle head on the fixing head to pop out. The first ring sleeve is equipped with a first buffer hook, and the second ring sleeve is equipped with a second buffer hook to prevent the needle head and needle body from popping out.

[0008] As a preferred embodiment of this application, the first buffer hook is welded and fixed to the first ring sleeve, and multiple first buffer hooks are distributed in a ring on the first ring sleeve. The cross-section of the first buffer hook is designed in a "C" shape, and the first buffer hook is made of buffer metal plate.

[0009] As a preferred embodiment of this application, the second buffer hook is welded and fixed to the second ring sleeve, and multiple second buffer hooks are distributed in a ring on the second ring sleeve. The cross-section of the second buffer hook is designed in a "C" shape, and the second buffer hook is made of buffer metal plate.

[0010] As a preferred embodiment of this application, a plurality of the lateral mounting grooves are distributed in a ring on the inner shell, and the lateral mounting grooves extend to the fixing head. The fixing head is integrally designed with the inner shell, and the needle body and the needle head are integrally designed. The extension length of the needle head is changed by the relative rotation of the needle body shell and the inner shell.

[0011] As a preferred embodiment of this application, the first ring sleeve and the second ring sleeve are threadedly fixed to the fixing head, and the upper and lower ends of the first ring sleeve and the second ring sleeve are connected with rubber rings by adhesive.

[0012] As a preferred embodiment of this application, the first buffer hook and the second buffer hook are connected by an elastic ring, and the surfaces of the first buffer hook and the second buffer hook are covered with anti-slip rubber sleeves by an adhesive. The edges of the first buffer hook and the second buffer hook are designed in an arc shape.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The needle assembly features an integrated design of the needle body and needle head, making the knitting machine more flexible and efficient to operate, and capable of meeting the needs of knitted materials of different thicknesses and densities. The length of the needle head extension can be easily adjusted by the relative rotation of the outer and inner shells of the needle body; this adjustment function enhances the applicability and flexibility of the knitting machine.

[0015] The introduction of the circular sleeves (first and second circular sleeves) not only prevents the needle from popping out, facilitating knitting operations, but also enhances the stability and durability of the structure by securing it to the fixed head via threads. The rubber rings bonded to the circular sleeves effectively absorb vibrations and reduce noise, providing the operator with a quieter and more comfortable working environment.

[0016] The design of the cushioning hooks (first and second cushioning hooks) significantly improves the safety and stability of the knitting machine. They are fixed to the ring sleeve by welding and distributed in a ring pattern, effectively preventing the needle head and needle body from accidentally popping out during operation. The "C"-shaped cross-section design of the cushioning hooks and the selection of cushioning metal plates enable them to absorb and disperse impact forces, enhancing the stability of the knitting machine under pressure. Simultaneously, the anti-slip rubber sleeve bonded to the surface of the cushioning hooks effectively prevents the operator from slipping during use, ensuring operational safety.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 - Figure 4 As shown, an improved needle for a knitting machine includes a needle body housing 1. An inner needle body 2 is designed inside the needle body housing 1, and the inner needle body 2 is tightly fixed to the needle body housing 1 by a sleeve and bolts, ensuring structural stability and durability.

[0024] The inner needle body 2 consists of several key parts, including an inner shell 21, lateral mounting grooves 22, needle body 23, and needle head 24. Multiple lateral mounting grooves 22 are formed on the side wall of the inner shell 21 for mounting the needle body 23. The lower end of the needle body 23 is fitted with the needle head 24 for actual knitting. A fixing head 25 is designed at the lower end of the inner shell 21, and a second ring sleeve 28 and a first ring sleeve 26 are respectively provided on the fixing head 25 and the inner shell 21. These two ring sleeves prevent the needle head 24 on the fixing head 25 from popping out, thus facilitating knitting operations.

[0025] To further improve the performance and operational comfort of the knitting machine, a first buffer hook 27 is installed on the first ring sleeve 26, while a second buffer hook 29 is installed on the second ring sleeve 28. These hooks are designed to prevent the needle head 24 and needle body 23 from accidentally popping out during operation, ensuring smooth knitting. The first buffer hook 27 is fixed to the first ring sleeve 26 by welding, and they are distributed in a ring on the first ring sleeve 26. The cross-section of the first buffer hook 27 is designed in a "C" shape, which is not only aesthetically pleasing but also practical, effectively absorbing and dispersing impact force. The first buffer hook 27 is made of a metal sheet with cushioning properties to ensure its elasticity and durability under pressure.

[0026] Similarly, the second cushioning hook 29 is also fixed to the second ring sleeve 28 by welding, and is distributed in a ring on the second ring sleeve 28. The cross-section of the second cushioning hook 29 is also designed in a "C" shape to provide a similar function and effect as the first cushioning hook 27. The second cushioning hook 29 is also made of cushioning metal sheet to ensure its stability and reliability during the knitting process.

[0027] Lateral mounting slots 22 are distributed in a ring on the inner housing 21, extending all the way to the fixing head 25, making the entire structure more compact and integrated. The fixing head 25 and the inner housing 21 are designed as a single unit, which not only simplifies the manufacturing process but also enhances the overall structural integrity. The needle body 23 and the needle head 24 are also designed as a single unit, making the knitting machine more flexible and efficient to operate. By rotating the needle body housing 1 and the inner housing 21 relative to each other, the extension length of the needle head 24 can be easily adjusted to accommodate knitted materials of different thicknesses and densities.

[0028] To further enhance the performance of the knitting machine, the first ring sleeve 26 and the second ring sleeve 28 are threaded onto the fixed head 25. Rubber rings are connected to the upper and lower ends of these two ring sleeves with adhesive; this design effectively absorbs vibration and noise, providing the operator with a quieter and more comfortable working environment. Furthermore, the first buffer hook 27 and the second buffer hook 29 are connected by elastic rings; this connection method not only ensures the flexibility of the hooks but also enhances their stability under pressure. To further improve operational comfort and safety, anti-slip rubber sleeves are adhesively attached to the surfaces of the first buffer hook 27 and the second buffer hook 29. The edges of these rubber sleeves are rounded to effectively prevent the operator from slipping during use, ensuring operational safety.

[0029] The threaded fixing parts on the first ring sleeve 26 and the second ring sleeve 28 need to be loosened to allow for subsequent adjustments. Rotating the needle body outer shell 1 and the inner shell 21 allows adjustment of the extended length of the needle head 24 to achieve the desired setting. After adjustment, carefully check that the length of the needle head 24 meets the requirements to ensure its accuracy satisfies operating standards. Re-secure the threaded parts of the first ring sleeve 26 and the second ring sleeve 28 to ensure the adjusted device is stable and reliable, and that loosening will not affect its performance.

[0030] To reduce vibration and noise during machine operation, rubber rings can be bonded to the upper and lower ends of the first ring sleeve 26 and the second ring sleeve 28. This effectively absorbs vibration and reduces noise. Connecting the first buffer hook 27 and the second buffer hook 29 with elastic rings enhances the stability of the device under pressure, preventing damage caused by vibration. To further improve operational safety, anti-slip rubber sleeves can be bonded to the surfaces of the first buffer hook 27 and the second buffer hook 29. This effectively prevents the operator from slipping during use, ensuring operational safety. After completing all protective measures, all welded and bonded parts must be carefully inspected for firmness, ensuring there is no loosening or damage, to guarantee the long-term stable operation of the equipment.
