Detailed Implementation
[0024] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0025] See Figures 1 to 3 The thread-drawing device provided by this utility model includes a thread-drawing arm 1 and a drive mechanism 2 for driving the thread-drawing arm 1 to swing laterally at a preset angle. In this embodiment, using... Figure 1 As a spatial reference, the Y-axis is defined as the horizontal direction, and the X-axis as the vertical direction. Based on the fundamental principles of textile technology, the draw arm adopts a symmetrical structure design, with its two arms symmetrically distributed about the X-axis. Therefore, it can be reasonably inferred that the swing angle of the draw arm also exhibits symmetrical characteristics during its swing. The "M"-shaped draw arm design provided in this embodiment helps to achieve specific swing and draw functions. Of course, depending on actual production needs and usage scenarios, the draw arm can also be flexibly set to other symmetrical shapes such as the "Y" shape to meet diverse textile process requirements.
[0026] The following is a detailed explanation using the example of the draw arm swinging towards the positive Y-axis. Drive mechanism 2 first drives the draw arm 1 to rotate clockwise around the first longitudinal axis M by a preset angle (this angle is set according to the required textile width, generally a large angle, such as 80°, 100°, or 120°), completing the initial swing motion. Subsequently, drive mechanism 2 again drives the draw arm 1 to rotate clockwise around the second longitudinal axis N by a preset compensation angle (this angle needs to be determined in conjunction with other textile mechanisms working in conjunction with the draw arm, and is usually a smaller angle value, such as 7°, 10°, or 20°), to compensate for the lateral swing angle of the draw arm.
[0027] The second clockwise rotation precisely compensates for the first oscillation. This unique oscillation method allows the drawing arm to closely and precisely coordinate with the weaving process, achieving high-quality jacquard weaving effects. It not only effectively enhances the pattern diversity of textile products but also significantly improves product quality stability, bringing higher production efficiency and better product output to the textile industry.
[0028] Specifically, the drive mechanism 2 includes two parts: a main drive component 21 and an auxiliary drive component 22. The two work together to achieve precise and stable swinging of the thread-drawing arm 1. The main drive component 21 is responsible for driving the thread-drawing arm 11 to complete a large-angle swing, so that the thread-clamping head 11 of the thread-drawing arm reaches the thread-drawing position in one go. The auxiliary drive component 22 performs fine compensation on the thread-drawing arm 1 after completing the large-angle swing, so that its thread-clamping head can be precisely docked with other textile mechanisms working together.
[0029] It should be noted that the structure and clamping principle of the wire clamping head 11 of the wire drawing arm are the same as those of existing technology, and will not be described again here.
[0030] The main drive assembly 21 includes a driven shaft 211 that is pulverizedly connected to the drawing arm 11, and a main drive motor 212 for driving the driven shaft 211 to oscillate laterally about its first longitudinal axis M. The auxiliary drive assembly 22 includes an auxiliary drive motor 221, a drive gear 222, and a driven gear 223. The drive gear 222 is mounted on the output shaft of the auxiliary drive motor 221 and meshes with the driven gear 223 to achieve transmission. The driven gear 223 is further pulverizedly connected to the driven shaft 211.
[0031] During operation, the auxiliary drive motor 221 drives the drive gear 22 to rotate. Due to the meshing relationship between the drive gear 222 and the driven gear 223, this rotation will cause the driven gear 223 to move laterally. At the same time, due to the transmission connection between the driven gear 223 and the driven shaft 211, the driven shaft 211 will also move laterally, thereby causing the drawing arm to move laterally.
[0032] To ensure stability throughout the oscillation process, the first longitudinal axis M and the second longitudinal axis N are set to be parallel to each other. This not only simplifies the mechanical structure but also improves the accuracy and reliability of the oscillation, enabling the drawing arm 1 to complete the textile task efficiently and accurately.
[0033] Furthermore, the drive mechanism 2 also includes a mounting base 23 and a steering base 24. The steering base 24 is movably connected to the mounting base 23 via a driven gear seat 224, providing swing support for the compensation angle of the drawing arm. The power shaft of the main drive motor 212 passes upward along the second longitudinal axis N through the mounting base 23 and connects to the drive wheel 213. The driven shaft 211 is mounted on the steering base 24 via a driven wheel 214. The driven wheel 214 is connected to the steering base 24 via a bearing, and the driven wheel 214 is connected to the drive wheel 213 via a transmission belt 215. When the drive wheel 213 rotates under the drive of the main drive motor 212, it drives the driven wheel 214 to rotate synchronously via the transmission belt 215, thereby driving the driven shaft 211 to achieve a swinging motion. The entire transmission system is compact and reasonable in design, ensuring high efficiency in power transmission and accuracy in swinging motion.
[0034] Furthermore, the mounting base 23 has a support portion 231 on one end face facing the steering seat 24, which is connected to the driven gear seat 224. The support portion 231 has a steering portion 232 that is coaxially arranged with the second longitudinal axis N and extends upward, providing precise positioning and guidance for subsequent steering and swinging actions.
[0035] The auxiliary drive motor 221 and the main drive motor 212 are arranged in the same direction and both are positioned on the mounting base 23. The power shaft of the auxiliary drive motor 221 passes through the support part 231 and is firmly connected to the drive gear 222 to ensure accurate power transmission. The driven gear seat 224 is movably mounted on the support part 231, ensuring both flexibility and stability of rotation. The steering seat 24 is fixedly connected to the driven gear seat 224, so that the rotation of the driven gear seat 224 can drive the steering seat 24 to rotate synchronously, thereby achieving precise swinging of the entire drawing arm.
[0036] Furthermore, the driven gear seat 224 is provided with an arc-shaped surface 2241 that slides in connection with the steering part 232. This arc-shaped surface 2241 not only conforms to the shape of the steering part 232 to ensure smooth and stable sliding, but also has an annular groove 2242 with an opening facing the steering part 232 in its middle. The driven gear 223 is integrally formed on the driven gear seat 224 as a half-tooth and is arranged on the side wall opposite to the opening of the annular groove 2242. This integrated design saves space, improves the compactness and reliability of the structure, and prevents tooth breakage.
[0037] Furthermore, the cross-sectional height of the driven gear 223 is consistent with that of the driving gear 222 to ensure smoothness and accuracy during meshing transmission. The mounting base 23 has a cylindrical hole 233 for housing the driving gear 222 and providing it with stable rotation space, and a guide groove 234 communicating with the cylindrical hole 233 to allow the driven gear 223 to swing laterally around the second longitudinal axis N, ensuring the flexibility and stability of the gear transmission mechanism.
[0038] Furthermore, the drawing device is equipped with a linkage cover plate 25, which swings synchronously with the driven gear seat 224 to ensure smooth and stable operation of the device, while protecting the transmission components of the motor. One end of the linkage cover plate 25 is coaxial with the second longitudinal axis N and is rotatably connected to the mounting base 23 via a bearing, ensuring both flexibility and precision in rotation. The other end of the linkage cover plate 25 covers the driven gear seat 224 and is fixedly connected to the steering seat 24, thereby achieving tight linkage between the driven gear seat 224, the linkage cover plate 25, and the steering seat 24, providing a strong guarantee for the efficient operation of the drawing device.
[0039] In summary, the thread-drawing device provided by this utility model achieves precise control and compensation of the swing angle of the thread-drawing arm through the coordinated work of the main drive component and the auxiliary drive component. At the same time, the device has a compact and reasonable structure, and the transmission system is efficient and accurate, bringing higher production efficiency and higher quality product output to the textile industry.
