Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine yarn guide needle technology, specifically a warp knitting machine yarn guide needle that integrates an anti-vibration needle bar and a bell-shaped guide groove. Background Technology

[0002] The warp knitting machine guide needle, also known as the eye needle, is the core loop-forming component of the warp knitting machine. It is made of alloy steel sheet by stamping. The head has a guide eye for the warp yarn to pass through. The base of the needle bar is thickened to ensure structural rigidity. Multiple guide needles are arranged in an orderly manner and fixed on the strip plate to form the overall structure of the guide bar. During operation, the guide needles move back and forth and laterally in sync with the guide bar. During the needle lifting and lowering process, the needles accurately realize the yarn padding in front of the needle and the lateral movement of the needle back, so as to guide the warp yarn to the needle mouth in an orderly manner to complete the loop-forming process.

[0003] The patent publication number "CN210066088U" discloses "a guide needle for a warp knitting machine, comprising a guide needle body, a water flow device, an installation device, and a guide needle head. The water flow device is connected to the lower part of the guide body, the installation device is connected to the lower part of the water flow device, and the guide needle head is connected to the lower part of the installation device, which can prevent the guide needle from overheating and affecting the knitting effect."

[0004] In the aforementioned patent, the existing warp knitting machine guide needles are not easy to disassemble, and it is troublesome to replace them partially when they are damaged. They also do not have good anti-vibration function and are prone to vibration during use, which will affect the performance.

[0005] To address this issue, the present invention provides a warp knitting machine guide needle that integrates an anti-vibration needle bar and a bell-shaped guide groove. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a warp knitting machine guide needle that integrates an anti-vibration needle bar and a bell-shaped guide groove, solving the problems of inconvenient disassembly and troublesome partial replacement of existing warp knitting machine guide needles when damaged.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a warp knitting machine guide needle integrating an anti-vibration needle bar and a trumpet-shaped guide groove, comprising a mounting frame, an anti-vibration component fixedly mounted on one side of the mounting frame, a guide groove body opened on one side of the mounting frame, and replacement components mounted on both sides of the mounting frame; the replacement components comprise a fixing frame and a disassembly frame one, the fixing frame being fixedly mounted on both sides of the mounting frame, the disassembly frame one being disposed on the top of the mounting frame, and a disassembly frame two being disposed on one side of the disassembly frame one, with guide needle bodies snapped into the inner walls of both the disassembly frame two and the disassembly frame one, a connecting plate one being fixedly mounted on both sides of the disassembly frame one, and a connecting plate two being fixedly mounted on both sides of the disassembly frame two, the connecting plate one and the connecting plate two being snapped into the fixing frame.

[0008] Furthermore, the replacement component also includes a second bolt, which is threadedly connected to one side of the fixing frame, and the second bolt is threadedly connected to both the first connecting plate and the second connecting plate.

[0009] The above technical solution achieves a stable connection, convenient assembly and disassembly, high connection accuracy, and ensures structural reliability during partial replacement.

[0010] Furthermore, the vibration-damping component includes a fixing block and a slot. The fixing block is fixedly installed on one side of the mounting bracket, and the slot is formed on one side of the fixing block. A connecting bracket is engaged with the inner side wall of the slot.

[0011] By adopting the above technical solution, vibration-damping components can be quickly located and installed, significantly improving assembly efficiency and simplifying the installation process.

[0012] Furthermore, the vibration-damping component also includes a locking rod, which is fixedly installed on one side of the connecting frame and is engaged with the yarn guide needle body.

[0013] By adopting the above technical solution, the yarn guide needle body is constrained at multiple points, which enhances installation stability and reduces vibration transmission.

[0014] Furthermore, the vibration-damping component also includes a bolt, which is threadedly connected to one side of the connecting frame, and the bolt is threadedly connected to the fixing block.

[0015] By adopting the above technical solution, the connection between the connecting frame and the fixing block is reinforced to prevent loosening due to vibration and ensure the long-lasting vibration resistance effect.

[0016] Furthermore, there are multiple yarn guide needle bodies, and these multiple yarn guide needle bodies are arranged sequentially among each other.

[0017] By adopting the above technical solution, multiple sets of warp yarns can be guided simultaneously, improving production efficiency and ensuring continuous and regular fabric.

[0018] Beneficial effects This invention provides a warp knitting machine yarn guide needle that integrates an anti-vibration needle bar and a bell-shaped guide groove. Compared with the prior art, it has the following advantages: 1. This warp knitting machine guide needle, which integrates an anti-vibration needle bar and a bell-shaped guide groove, allows for partial replacement of the guide needle by changing components. This reduces replacement costs and eliminates the need to replace the entire guide bar or needle bar assembly, lowering overall expenses for spare parts procurement and downtime maintenance. It also avoids waste of non-faulty parts, improving the economy and flexibility of equipment operation and maintenance. Only the damaged guide needle needs to be replaced individually, without disassembling the entire guide bar structure, shortening maintenance time, reducing the impact of downtime on production schedule, and making spare parts consumption more precise. Long-term use can significantly reduce equipment operating costs.

[0019] 2. This warp knitting machine guide needle, which integrates an anti-vibration needle bar and a bell-shaped guide groove, achieves excellent vibration resistance through its anti-vibration components, resulting in better overall performance. It ensures smoother needle movement during high-speed knitting, more uniform warp yarn tension, and reduces issues such as yarn breakage and yarn padding deviation. This significantly improves fabric texture regularity and surface quality, effectively weakening vibration transmission caused by high-speed oscillation, reducing frictional wear between the guide needle and the tongue needle, extending component lifespan, and ensuring stable loop-forming accuracy. It is suitable for high-speed warp knitting processes, contributing to the production of high-quality fabrics. Attached Figure Description

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0024] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1 to 4 This application provides a warp knitting machine guide needle integrating an anti-vibration needle bar and a bell-shaped guide groove, including a mounting frame 1. An anti-vibration component 2 is fixedly installed on one side of the mounting frame 1, and a guide groove body 3 is opened on one side of the mounting frame 1. Replacement components 4 are respectively installed on both sides of the mounting frame 1. The replacement components 4 include a fixing frame 41 and a disassembly frame 42. The fixing frame 41 is fixedly installed on both sides of the mounting frame 1, and the disassembly frame 42 is located on the top of the mounting frame 1. A disassembly frame 43 is provided on one side of the disassembly frame 42. The disassembly frame 43 and the disassembly frame 42 are connected to each other. Each side wall is fitted with a yarn guide needle body 44. Connecting plates 45 are fixedly installed on both sides of the first disassembly frame 42, and connecting plates 46 are fixedly installed on both sides of the second disassembly frame 43. Connecting plates 45 and 46 are respectively engaged with the fixed frame 41. The replacement component 4 also includes bolts 47. Bolts 47 are threaded to one side of the fixed frame 41. Bolts 47 are threaded to connecting plates 45 and 46 respectively. There are multiple yarn guide needle bodies 44, and the multiple yarn guide needle bodies 44 are arranged sequentially.

[0026] In this embodiment, the fixing frame 41 is threadedly connected to the connecting plate 45 and the connecting plate 46 by bolt 2 47, which firmly fixes the disassembly frame 42 and the disassembly frame 43 to both sides of the mounting frame 1. This ensures that the yarn guide needle body 44 is tightly engaged with the inner sidewall of the disassembly frame 42 and the disassembly frame 43, preventing displacement of the yarn guide needle body 44 during high-speed reciprocating motion. After the yarn is guided by the flared opening of the guide groove body 3, it smoothly enters the yarn guide channel of each yarn guide needle body 44. The clamping rod 24 of the anti-vibration component 2 offsets the vibration impact force of the yarn guide needle body 44 through elastic limiting, avoiding yarn shaking, tangling or breakage. This ultimately achieves high-precision and low-loss yarn guiding operation. When the yarn guide needle body 44 needs maintenance or replacement, simply loosen bolt 2 47 to disassemble the disassembly frame 42 and the disassembly frame 43, and easily remove the yarn guide needle body 44, greatly improving equipment maintenance efficiency.

[0027] Reference Figures 1 to 4 In one aspect of this embodiment, the vibration damping component 2 includes a fixing block 21 and a slot 22. The fixing block 21 is fixedly installed on one side of the mounting frame 1, and the slot 22 is opened on one side of the fixing block 21. A connecting frame 23 is engaged with the inner side wall of the slot 22. The vibration damping component 2 also includes a locking rod 24, which is fixedly installed on one side of the connecting frame 23 and is engaged with the yarn guide needle body 44. The vibration damping component 2 also includes a bolt 25, which is threadedly connected to one side of the connecting frame 23 and threadedly connected to the fixing block 21.

[0028] In this embodiment, the vibration-resistant installation of the yarn guide needle body 44 is first achieved through the vibration-resistant component 2: the connecting frame 23 is aligned with the slot 22 of the fixing block 21 and locked in place, so that the locking rod 24 on one side of the connecting frame 23 is precisely engaged with the yarn guide needle body 44. Then, the bolt 25 on one side of the connecting frame 23 is tightened, and the position of the connecting frame 23 is locked by the threaded connection between the bolt 25 and the fixing block 21, so that the locking rod 24 continuously forms a lateral limit on the yarn guide needle body 44, avoiding the yarn guide needle body 44 from vibrating violently due to high-frequency movement when the warp knitting machine is working. At the same time, the guide groove body 3 opened on one side of the mounting frame 1 adopts a flared structure design to provide a widened guide channel for yarn transmission, ensuring that the yarn is neatly arranged before entering the yarn guide needle body 44, reducing transmission resistance.

[0029] Working principle: First, the anti-vibration installation of the yarn guide needle body 44 is achieved through the anti-vibration component 2: the connecting frame 23 is aligned with the slot 22 of the fixing block 21 and locked in place, so that the locking rod 24 on one side of the connecting frame 23 is precisely engaged with the yarn guide needle body 44. Then, the bolt 25 on one side of the connecting frame 23 is tightened, and the position of the connecting frame 23 is locked by the threaded connection between the bolt 25 and the fixing block 21, so that the locking rod 24 continuously forms a lateral limit on the yarn guide needle body 44, avoiding the yarn guide needle body 44 from vibrating violently due to high-frequency movement when the warp knitting machine is working. At the same time, the guide groove body 3 opened on one side of the mounting frame 1 adopts a flared structure design, providing a widened guide channel for yarn transmission, ensuring that the yarn is neatly arranged before entering the yarn guide needle body 44, and reducing transmission resistance.

[0030] The fixing frame 41 is connected to the connecting plate 45 and the connecting plate 46 by bolt 2 47, which firmly fixes the disassembly frame 42 and the disassembly frame 43 to both sides of the mounting frame 1. This ensures that the yarn guide needle body 44 is tightly engaged with the inner sidewall of the disassembly frame 42 and the disassembly frame 43, preventing displacement of the yarn guide needle body 44 during high-speed reciprocating motion. After the yarn is guided by the flared opening of the guide groove body 3, it smoothly enters the yarn guide channel of each yarn guide needle body 44. The clamping rod 24 of the anti-vibration component 2 offsets the vibration impact force of the yarn guide needle body 44 through elastic limiting, avoiding yarn shaking, tangling or breakage. This ultimately achieves high-precision and low-loss yarn guiding operation. When the yarn guide needle body 44 needs maintenance or replacement, simply loosen bolt 2 47 to disassemble the disassembly frame 42 and the disassembly frame 43, and easily remove the yarn guide needle body 44, greatly improving equipment maintenance efficiency.
