Description

Technical Field

[0001] This utility model relates to the technical field of yarn guiding devices, and more specifically, to a yarn guiding device for a spinning machine. Background Technology

[0002] A ring spinning frame is a spinning machine that takes semi-finished roving or sliver, drafts, twists, and winds it into fine yarn bobbins during the spinning process. Specifically, the sliver is drafted and twisted on a roving frame to produce roving; the roving is drafted and twisted on a ring spinning frame to produce fine yarn; the sliver is drafted and twisted on a roving frame to produce roving; a combing machine combs the fibers to produce combed sliver; a carding machine combines the sliver, and card rows improve the sliver structure; finally, the roving is further twisted and spun into fine yarn on a ring spinning frame. The yarn guiding step is crucial in the ring spinning frame process.

[0003] For example, patent application number 202421464670.4 discloses a yarn guiding device for a spinning machine, including two mounting frames connected by a yarn guiding rod. Several evenly distributed movable plates are mounted on the yarn guiding rod, each with a circular groove outside the guide rod. A pressing and clamping assembly is located within each movable plate, and a mounting cylinder is installed on the top of the movable plate. This device can appropriately adjust the yarn tension. However, the yarn is only guided at the top of the guide wheel during the yarn guiding process, which is too limited. Furthermore, when the yarn tension is unsuitable, the existing structure cannot adjust the yarn trajectory in a timely and effective manner, making the yarn susceptible to tension changes and prone to skipping, thus affecting the normal operation of the spinning machine and the yarn quality.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

By improving stability, flexibility and production efficiency, it can not only ensure the smoothness and accuracy of the yarn guiding process, but also significantly improve the quality of textiles, reduce maintenance costs and resource waste, and provide textile enterprises with an efficient, reliable and economical solution.

[0027] In one embodiment, for the support rod 3 and the fixing mechanism 5, the top end of the support rod 3 is provided with a fixing groove 301 that cooperates with the fixing mechanism 5, and fixing holes 302 are provided on both sides of the fixing groove 301; the fixing mechanism 5 includes a slider 501 disposed inside the fixing groove 301, the slider 501 has a T-shaped cross-section, and both ends of the slider 501 are provided with cavities 502, and a drive rod 503 passing through the top end of the slider 501 is disposed inside the cavity 502. In addition, in a specific application, the top end of the drive rod 503 is provided with a knob, and the bottom end of the drive rod 503 is connected to the cavity 502 by a bearing. A bevel gear 504 is provided on the outer side of the bottom of the drive rod 503; driven rods 505 are provided through both sides of the cavity 502. In addition, in a specific application, the driven rods 505 are connected to the slider 501 by a bearing, and one end of the driven rod 505 is connected to the outer side of the cavity 502 by a bearing. A second bevel gear 506 is provided to mesh with a first bevel gear 504; both ends of the bottom of the slider 501 are fitted with inserts 507 that cooperate with the fixing holes 302. In addition, in specific applications, the two sets of driven rods 505 and the two sets of inserts 507 are arranged in a mirror symmetry; the outer side of the driven rod 505 away from the second bevel gear 506 is provided with a thread 5051; the cross-section of the insert 507 is a directional structure, and one end of the insert 507 is provided with a threaded hole 5071 that cooperates with the thread 5051, thereby realizing the fixation of the anti-skip yarn guiding mechanism 6. With the cooperation of the insert 507 and the fixing hole 302, the anti-skip yarn guiding mechanism 6 can be fixed in different positions, greatly improving the flexibility and adaptability of the device. The anti-skip yarn guiding mechanism 6 can also be easily disassembled and replaced, and different specifications of anti-skip yarn guiding mechanisms 6 can be replaced to adapt to different specifications of yarn or process requirements.

[0028] The working principle of the fixing mechanism 5 is as follows: by rotating the knob, the drive rod 503 is rotated, and then the driven rod 505 is rotated under the action of the meshing of the first bevel gear 504 and the second bevel gear 506. Then, with the cooperation of the thread 5051 and the first threaded hole 5071, the insert block 507 is inserted into the inside of the device fixing hole 302, and then the slider 501 can be fixed, so that the slider 501 can be stably placed inside the support rod 3.

[0029] In one embodiment, the anti-skip yarn guiding mechanism 6 includes a mounting bracket 601 disposed at the top of the slider 501. In practical applications, the mounting bracket 601 is detachably connected to the slider 501. The mounting bracket 601 has a U-shaped cross-section, and a first yarn guide wheel 602 is disposed inside the U-shaped structure. Furthermore, in practical applications, the first yarn guide wheel 602 is connected to the mounting bracket 601 via a pin. Guide rods 603 are symmetrically arranged on one side of the top of the mounting bracket 601. A movable plate 604 is disposed on the outer side of the guide rods 603. A threaded rod 605 penetrates the middle of the top of the movable plate 604. The sidewalls of the movable plate 604... A second yarn guide wheel 606 is provided. In specific applications, the second yarn guide wheel 606 is connected to the moving plate 604 by a pin.

[0030] The working principle of the anti-skip yarn guiding mechanism 6 is as follows: First, rotate the threaded rod 605. Then, with the cooperation of the threaded rod 605 and the threaded hole 6041, the moving plate 604 slides on the outside of the guide rod 603. This drives the guide wheel 606 to move upward, causing the annular plate 6061 to leave the annular groove 6021. The yarn can then be placed in the middle of the guide wheel 602. Then, rotate the threaded rod 605 in the opposite direction, causing the moving plate 604 to drive the guide wheel 606 to move downward, causing the annular plate 6061 to enter the annular groove 6021. This prevents the yarn from skipping during the yarn guiding process and ensures the stability of the yarn guiding process.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In practical applications, firstly, based on the specifications or process requirements of the yarn, different specifications of anti-skip yarn guiding mechanisms 6 are selected and installed on the fixing mechanism 5. Then, the fixing mechanism 5 is installed on the support rod 3. Based on the requirements of the yarn during the conductor guiding process, the fixing mechanism 5 is installed in different positions inside the support rod 3. Then, the yarn is installed into the anti-skip yarn guiding mechanism 6 to achieve the conductor guiding of the yarn.

[0033] In summary, with the help of the above-mentioned technical solution of this utility model, the structure of this utility model is reasonable and reliable. By improving stability, flexibility and production efficiency, it can not only ensure the smoothness and accuracy of the yarn guiding process, but also significantly improve the quality of textiles, reduce maintenance costs and resource waste, and provide textile enterprises with an efficient, reliable and economical solution. By setting the fixing mechanism 5, the anti-skip yarn guiding mechanism 6 is fixed. With the cooperation of the insert block 507 and the fixing hole 302, the anti-skip yarn guiding mechanism 6 can be fixed in different positions, greatly improving the flexibility and adaptability of the device. The anti-skip yarn guiding mechanism 6 can also be easily disassembled and replaced, and different specifications of anti-skip yarn guiding mechanisms 6 can be replaced to adapt to different specifications of yarn or process requirements. By setting the anti-skip yarn guiding mechanism 6, the stability of the yarn during the guiding process is achieved. With the cooperation of the first guide wheel 602 and the second guide wheel 606, the yarn can be effectively prevented from falling off due to external vibration or changes, ensuring the smooth operation of the yarn during the guiding process and avoiding the occurrence of skipped yarn.
