Description

Technical Field

[0001] The utility model relates to the technical field of textile yarn fixed-distance traction, in particular to a fixed-distance traction device for textile yarns. Background Art

[0002] With the development of the production industry and the improvement of people's living standards, people's requirements for textile materials are getting higher and higher. High-quality textile materials can be used to weave high-end textiles to meet people's usage needs. Textile materials refer to fibers and fiber products, specifically manifested as fibers, yarns, fabrics and their composites. In modern textiles, the research and development of new textile materials, especially the development and use of nanofibers, have broken through the traditional concept of textile materials, and textile materials have become an important part of soft matter materials.

[0003] Most of the existing traction devices only rely on a single traction shaft to perform fixed-distance traction on the yarn. In this way, the yarn is changed from a straight line to an oblique line, so it is more cumbersome to calculate the length of the fixed-distance traction. Therefore, it is necessary to design a fixed-distance traction device that can directly obtain the traction length. Summary of the Utility Model

[0004] Based on this, in view of the above technical problems, it is necessary to provide a fixed-distance traction device for textile yarns.

[0005] In order to achieve the above object, the utility model provides a fixed-distance traction device for textile yarns, including a frame and a yarn. Two guide rollers I and II are rotatably installed on the frame. The frame is rotatably connected with a fixed-direction shaft I, a fixed-direction shaft II, a fixed-direction shaft III and a fixed-direction shaft IV which are arranged flush. A moving frame I and a moving frame II are slidably clamped on the frame. Two parallel rotating shafts are rotatably connected to both the moving frame I and the moving frame II. The frame is provided with a driving mechanism for driving the movement of the moving frame I and the moving frame II. The gap between the horizontal projections on the side wall of the frame of the fixed-direction shaft I, the fixed-direction shaft II, the fixed-direction shaft III, the fixed-direction shaft IV and the closest rotating shaft is the same as the diameter of the yarn.

[0006] Preferably, rotating sleeves are movably connected to the fixed-direction shaft I, the fixed-direction shaft II, the fixed-direction shaft III, the fixed-direction shaft IV and the rotating shafts.

[0007] Preferably, limit blocks are installed at the tops of the fixed-direction shaft I, the fixed-direction shaft II, the fixed-direction shaft III, the fixed-direction shaft IV and the rotating shafts, and the limit blocks are arranged in cooperation with the rotating sleeves.

[0008] Preferably, the moving frame I and the moving frame II are symmetrically arranged about the center.

[0009] Preferably, two card slots are provided on the frame, and the moving frame I and the moving frame II are both slidably clamped in the card slots.

[0010] Preferably, the driving mechanism includes a mounting plate and a linear actuator. The mounting plate is mounted on the frame, the linear actuator is mounted on the mounting plate, and the output end of the linear actuator is connected to the first moving frame or the second moving frame.

[0011] Compared with the prior art, the technical solution has at least one of the following beneficial effects:

[0012] Through the cooperative arrangement of the first guiding shaft, the second guiding shaft, the third guiding shaft and the fourth guiding shaft, when the first moving frame or the second moving frame drives the yarn for fixed-distance traction through the rotating shaft, the distance that the yarn is tractioned is twice the distance that the first moving frame or the second moving frame moves, making it easy to obtain the fixed-distance traction distance;

[0013] Through the cooperative arrangement of the first moving frame and the second moving frame, it changes the disadvantage that most fixed-distance traction devices have only one adjusting device with a small adjustment range, increases the fixed-distance traction length, and enlarges the application range of the device;

[0014] Through the arrangement of the rotating sleeve, different rotating sleeves can be replaced to be suitable for yarns of different thicknesses. Description of the Drawings

Detailed Embodiment

[0018] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be made with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0019] Please refer to Figures 1 to 2, an embodiment of the present application provides a fixed - stroke traction device for textile yarns, including a frame 1 and a yarn 101. Two first guide rollers 2 and a second guide roller 3 are rotatably installed on the frame 1. A first fixed - direction shaft 4, a second fixed - direction shaft 5, a third fixed - direction shaft 6, and a fourth fixed - direction shaft 7 are rotatably connected to the frame 1 and are arranged flush. A first moving frame 8 and a second moving frame 9 are slidably clamped on the frame 1. Two parallel rotating shafts 10 are rotatably connected to both the first moving frame 8 and the second moving frame 9. A driving mechanism for driving the first moving frame 8 and the second moving frame 9 to move is installed on the frame 1. The gap between the horizontal projections on the side wall of the frame 1 of the first fixed - direction shaft 4, the second fixed - direction shaft 5, the third fixed - direction shaft 6, the fourth fixed - direction shaft 7 and the closest rotating shaft 10 is the same as the diameter of the yarn 101.

[0020] In this embodiment, the yarn 101 is straightened and guided by the two first guide rollers 2 and the second guide roller 3. The yarn 101 passes through in the order of the first fixed - direction shaft 4, the two rotating shafts 10 on the first guide frame 8, the second fixed - direction shaft 5, the third fixed - direction shaft 6, the two rotating shafts 10 on the second guide frame 9, and the fourth fixed - direction shaft 7. Because the gap between the horizontal projections on the side wall of the frame 1 of the first fixed - direction shaft 4, the second fixed - direction shaft 5, the third fixed - direction shaft 6, the fourth fixed - direction shaft 7 and the closest rotating shaft 10 is the same as the diameter of the yarn 101, when the first moving frame 8 and the second moving frame 9 fixed - stroke traction the yarn through the rotating shafts 10 thereon, the changed length of the yarn is twice the moving distance of the first moving frame 8 and the second moving frame 9, thus facilitating the calculation of the fixed - stroke traction length.

[0021] In some embodiments, to further improve the practicability of the device, rotating sleeves 11 are movably connected to the first fixed - direction shaft 4, the second fixed - direction shaft 5, the third fixed - direction shaft 6, the fourth fixed - direction shaft 7, and the rotating shafts 10. Here, the movable connection means that the rotating sleeve 11 can be rotatably connected and slidably connected thereon, without the situation of gap and shaking, so different rotating sleeves 11 can be replaced to adapt to yarns of different thicknesses. At this time, the gap between the horizontal projection on the side wall of the frame 1 of the rotating sleeve 11 and the closest rotating shaft 10 is the same as the diameter of the yarn 101.

[0022] In some embodiments, to limit the rotating sleeve 11, limit blocks 12 are installed at the tops of the first fixed - direction shaft 4, the second fixed - direction shaft 5, the third fixed - direction shaft 6, the fourth fixed - direction shaft 7, and the rotating shafts 10. The limit blocks 12 are arranged in cooperation with the rotating sleeves 11. The limit blocks 12 can be installed by threads for easy disassembly.

[0023] In some embodiments, to ensure stable adjustment, the first moving frame 8 and the second moving frame 9 are arranged symmetrically about the center. When arranged in the same direction, the yarn 101 should pass through the same side of the second guiding shaft 5 and the third guiding shaft 6. Thus, when the first moving frame 8 and the second moving frame 9 are both adjusted and then reset, the yarn 101 is not stably attached to the second guiding shaft 5 and the third guiding shaft 6, and it is prone to slipping downward. However, when arranged symmetrically about the center, the yarn 101 passes through different sides of the second guiding shaft 5 and the third guiding shaft 6. The larger contact area results in a greater frictional force, making it difficult for the yarn 101 to slip.

[0024] In some embodiments, to facilitate the sliding and clamping connection of the first moving frame 8 and the second moving frame 9 on the frame 1, two slots 15 are provided on the frame 1, and the first moving frame 8 and the second moving frame 9 are both slidably clamped in the slots 15.

[0025] In some embodiments, to facilitate driving the first moving frame 8 and the second moving frame 9 to move for fixed-distance traction, the driving mechanism includes a mounting plate 13 and a linear actuator 14. The mounting plate 13 is mounted on the frame 1, the linear actuator 14 is mounted on the mounting plate 13, and the output end of the linear actuator 14 is connected to the first moving frame 8 or the second moving frame 9.

[0026] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0027] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
