Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, to a weft yarn guiding device and a textile machine. Background Technology

[0002] In the field of textile machinery, optimizing weft yarn guiding devices has always been key to improving weaving efficiency and quality. Traditional yarn guiding mechanisms mostly adopt fixed designs or simple linear reciprocating motions. While this structure is simple and reliable, it suffers from problems such as a single yarn guiding path and uneven yarn tension, easily leading to defects such as uneven density on the fabric surface. As the textile industry continues to demand higher production efficiency and product quality, this simple yarn guiding method is no longer sufficient to meet the needs of modern high-efficiency weaving.

[0003] To address the aforementioned issues, existing technologies employ yarn guiding mechanisms driven by servo motors or pneumatic devices, achieving complex yarn guiding trajectories through programming control. While these solutions improve yarn guiding accuracy, they suffer from drawbacks such as complex structure, high cost, and difficult maintenance. In particular, for small and medium-sized enterprises, the high cost of equipment modification and complex control systems have become major obstacles to technological upgrades. Furthermore, the mechanical reset accuracy of these devices often relies on expensive sensors and control systems, which can easily lead to positioning deviations after long-term use, affecting weaving quality. Therefore, to address the aforementioned technical problems, this paper proposes a weft yarn guiding device and a textile machine. Utility Model Content

[0004] The purpose of this invention is to provide a weft yarn guiding device and a textile machine. It utilizes a rotating plate to push a limiting strip to slide laterally and stretch a tension spring. After the contact is broken, the tension spring automatically resets, causing the weft yarn guiding path to swing regularly from side to side. This, combined with the synchronous movement of the linkage roller, enables dynamic adjustment. The structure is simple and reliable, and the guiding trajectory optimization is achieved solely through mechanical linkage, without the need for complex control. The tension spring and the slot work together to ensure positioning accuracy. It is low in cost and can effectively improve spinning uniformity and efficiency.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Example:

[0026] Please see Figures 1-4 The weft yarn guiding device and textile machine proposed in this application include a spinning machine body 1, crossbars 8, and a fixing plate 15. A mounting frame 2 is fixedly connected to the upper side of the spinning machine body 1, and a spinning device 3 is fixedly connected to one end of the mounting frame 2. There are two sets of crossbars 8, and the two sets of crossbars 8 are respectively fixedly connected to the mounting frame 2 by a first upright plate 6 and a second upright plate 7. The outer side of the crossbar 8 is provided with a mounting groove 9, and the inner side of the mounting groove 9 is connected to a guiding mechanism through a tension spring 14, and the guiding mechanism is slidably connected to the inner side of the mounting groove 9. The fixing plate 15 is fixedly connected to the lower side of the guiding mechanism, and a deflection mechanism is installed between the first upright plate 6 and the second upright plate 7.

[0027] The guiding mechanism includes a limiting strip 10 and a cavity 11. The limiting strip 10 is slidably connected to the inside of the mounting groove 9, and the cavity 11 is formed inside the limiting strip 10. The limiting strip 10 is fixedly connected to the tension spring 14. The cavity 11 provides initial guidance for the weft yarn, preventing it from becoming entangled and disorderly with other weft yarns. The smooth inner wall design of the cavity 11 also reduces frictional resistance during weft yarn operation, improving guiding efficiency.

[0028] The tension springs 14 are arranged in two sets symmetrically. This symmetrical arrangement ensures that the limiting strip 10 is subjected to uniform force during sliding, guaranteeing smooth movement. At the same time, the double tension spring structure provides sufficient restoring force, enabling the limiting strip 10 to return to its initial position quickly and accurately.

[0029] The mounting groove 9 has slots 12 on its upper and lower sides, and locking blocks 13 are fixedly connected to the upper and lower sides of the limiting strip 10, with the locking blocks 13 slidably connected to the inner side of the slots 12. The cooperation between the locking blocks 13 and the slots 12 serves both as a guide and as a means to prevent the limiting strip 10 from falling out of the mounting groove 9. This limiting structure is simple and reliable, and can effectively control the movement trajectory of the limiting strip 10.

[0030] The fixing plate 15 is fixedly connected to the lower side of the limiting strip 10. As a force-bearing component, the fixing plate 15 can transmit the thrust of the rotating plate 18 to the limiting strip 10 to achieve lateral movement. Its flat contact surface ensures stable contact with the rotating plate 18, making the power transmission smoother and more reliable.

[0031] The deflection mechanism includes a rotating shaft 17 and rotating plates 18. The rotating shaft 17 is rotatably connected between the first upright plate 6 and the second upright plate 7. The rotating plates 18 are fixedly connected to the outside of the rotating shaft 17, and there are two sets of rotating plates 18 arranged symmetrically. The ends of the rotating plates 18 abut against the fixed plate 15. The rotational motion of the rotating plates 18 is converted into the linear motion of the limiting strip 10 through abutment against the fixed plate 15. The symmetrical arrangement of the rotating plates 18 can balance the force applied to the limiting strip 10, reducing vibration and noise.

[0032] A drive motor 16 is fixedly connected to the outside of the first upright plate 6, and the drive motor 16 is also fixedly connected to the rotating shaft 17. The drive motor 16 provides a stable and reliable power source for the entire guiding device. The direct connection between the drive motor 16 and the rotating shaft 17 simplifies the transmission structure and improves energy transfer efficiency.

[0033] The mounting frame 2 is laterally slidably connected to a fixed frame 4, and a roller 5 is rotatably connected to the end of the fixed frame 4. A connecting rod 19 is fixedly connected between the limiting strip 10 and the fixed frame 4. The linkage design of the connecting rod 19 allows the roller 5 to move synchronously with the limiting strip 10, realizing the coordinated guidance of the weft yarn. The rotatable connection design of the roller 5 further reduces the frictional resistance during weft yarn operation, protecting the yarn quality.

[0034] A textile machine, including a weft yarn guiding device, is also proposed.

[0035] The working principle of the weft yarn guiding device and textile machine based on the embodiment is as follows: When the device is running, the weft yarn first passes through the cavity 11 opened inside the limiting strip 10 in the guiding mechanism. The limiting effect of the cavity 11 realizes the directional guidance of the weft yarn. When the drive motor 16 starts, it drives the rotating shaft 17 and the symmetrical rotating plates 18 on both sides to rotate synchronously. During the rotation, the end of the rotating plate 18 abuts against the fixed plate 15, pushing the limiting strip 10 connected to it to slide laterally along the mounting groove 9 of the crossbar 8. At this time, the two sets of tension springs 14 symmetrically arranged are stretched and stored. When the rotating plate 18 continues to rotate until it is out of contact with the fixed plate 15, the tension springs 14 are released. The elastic potential energy is released, pulling the limiting strip 10 to slide back and reset. The reset positioning is achieved through the precise contact between the locking blocks 13 on both sides of the limiting strip 10 and the locking groove 12. The reciprocating motion causes the weft yarn to generate a lateral periodic displacement during the guiding process. In conjunction with the fixed frame 4, which is linked to the limiting strip 10 through the connecting rod 19, the roller 5 is driven to slide laterally in sync, forming an optimized guiding path. This structure achieves dynamic adjustment of the guiding trajectory through mechanical linkage, which can improve the spinning uniformity without the need for a complex control system. At the same time, the cooperation between the tension spring 14 and the locking groove 12 ensures the motion accuracy. The overall structure is compact and has low manufacturing cost, effectively improving the spinning efficiency.
