Description

Technical Field

[0001] This utility model relates to the field of yarn combing devices, specifically a yarn combing device for chemical fiber textiles. Background Technology

[0002] In the chemical fiber textile industry, yarn combing is a crucial step in the production process, and its effectiveness directly affects the quality of subsequent textile products. High-quality combing makes the fibers in the yarn more neat and uniform, reduces defects such as fiber knots and impurities, and improves the strength, toughness, and appearance quality of the yarn.

[0003] However, traditional yarn carding devices have many shortcomings in practical applications. On the one hand, for different types and thicknesses of synthetic fiber yarns, traditional devices often have difficulty flexibly adjusting the spacing between carding components, resulting in inappropriate carding force. Either over-carding causes fiber damage, or under-carding leaves the yarn with many messy fibers, failing to meet diverse production needs.

[0004] On the other hand, the design of the carding structure in traditional equipment is not reasonable enough. The guiding and limiting effect on the yarn during the carding process is poor, and the yarn is prone to problems such as deviation and tangling, which not only affects the carding efficiency but also reduces the carding quality. At the same time, some equipment lacks an effective pre-carding mechanism and directly performs fine carding, which makes the carding burden too heavy, makes it difficult to achieve the ideal carding effect, and increases the difficulty of subsequent processes.

[0005] In addition, the adjustment mechanism of traditional devices is complicated to operate, has low adjustment accuracy, and is difficult to adjust parameters quickly and accurately according to production needs. It has poor adaptability and cannot adapt well to the efficient and high-quality production of the modern chemical fiber textile industry. Therefore, we have proposed a yarn combing device for chemical fiber textiles. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a yarn combing device for chemical fiber textiles, which solves the aforementioned problems.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a yarn combing device for chemical fiber textiles, comprising a concave bracket, a bottom combing shaft rotatably mounted on the inner side of the concave bracket, height adjustment components provided on both sides of the concave bracket, a top combing shaft provided between the height adjustment components on both sides, and the top combing shaft corresponding vertically to the bottom combing shaft.

[0008] Preferably, the outer wall surface of the bottom combing shaft has multiple sets of arc-shaped grooves at equal intervals, and the outer wall surface of the top combing shaft has multiple sets of arc-shaped protrusions at equal intervals, the positions of the arc-shaped protrusions and the top combing shaft are aligned.

[0009] Preferably, the height adjustment component includes a concave mounting bracket and a servo cylinder. The concave mounting bracket is disposed on both sides of the concave support, and the servo cylinder is fixedly installed on the bottom inner wall of the concave mounting bracket. The output shaft of the servo cylinder is connected to the motor structure on both sides of the top combing shaft.

[0010] Preferably, the motor structure includes L-shaped motor mounting seats located on both sides of the top combing shaft. A motor is fixedly mounted on the L-shaped motor mounting seat. The output shaft of the motor passes through one side of the L-shaped motor mounting seat and is fixedly connected to the side of the top combing shaft. The bottom of the L-shaped motor mounting seat is fixedly connected to the output shaft of the servo cylinder. The motor is used to drive the top combing shaft to rotate.

[0011] Preferably, a side shaft is provided on both sides of the bottom combing shaft, and a pulling structure is provided at both ends of the side of the side shaft, with the connecting end of the pulling structure connected to both sides of the concave bracket.

[0012] Preferably, side grooves are provided on both sides of the pull structure of the concave bracket, and springs are fixedly installed inside the side grooves.

[0013] Preferably, the pulling structure includes a slider and a concave connecting block. The slider is slidably installed inside the side groove, and the concave connecting block is fixedly installed at one end of the slider extending to the outside of the side groove. The concave connecting block is U-shaped and is rotatably connected to the side shaft around one side of the concave bracket.

[0014] Compared with the prior art, this utility model provides a yarn combing device for chemical fiber textiles, which has the following beneficial effects:

[0015] It can flexibly adjust the carding spacing to adapt to the carding needs of different types of synthetic fiber yarns. Through the servo cylinder in the height adjustment component, the top carding shaft can be precisely driven up and down, thereby quickly and accurately changing the spacing between the top and bottom carding shafts. This effectively avoids the problems of over-carding damaging fibers or under-carding leaving messy fibers due to the fixed spacing in traditional devices, ensuring that appropriate carding force can be applied to various types and thicknesses of synthetic fiber yarns, thus improving the versatility and applicability of the device.

[0016] The combing effect is superior, significantly improving yarn quality. The arc-shaped grooves on the bottom combing shaft and the arc-shaped protrusions on the top combing shaft work together to effectively clamp and comb the yarn during the combing process, making the fibers more neat and uniform, and reducing defects such as fiber knots and impurities. At the same time, the side shafts on both sides, under the action of springs, fit against the bottom combing shaft, providing good guidance and limiting for the yarn, effectively preventing the yarn from shifting or tangling during the combing process, ensuring the stability of the combing process, and further improving the combing quality.

[0017] Equipped with an effective pre-carding function, the device reduces the burden on subsequent processes. Through the arc-shaped grooves on the bottom carding shaft and the cooperation of the side shafts with the bottom carding shaft, the device pre-cards the yarn before it enters the area between the top and bottom carding shafts for primary carding, thus initially straightening the yarn. This avoids the problem of excessive burden when traditional devices directly perform fine carding, making the carding process more orderly and efficient, laying a good foundation for subsequent fine carding processes, and helping to improve overall production efficiency.

[0018] The adjustment operation is simple and highly precise. The height adjustment component is driven by a servo cylinder, which is more convenient to operate and has higher adjustment accuracy compared to the complex adjustment mechanism of traditional devices. It can quickly respond to changes in production needs and adjust combing parameters in a timely manner. This greatly shortens the equipment adjustment time, improves production flexibility and efficiency, and better adapts to the high-efficiency and high-quality production requirements of the modern fiber textile industry.

[0027] Please see Figure 1-6 A yarn combing device for chemical fiber textiles, with the following structure:

[0028] Concave bracket 1: Serves as the basic support structure for the entire device, providing an installation platform for other components. A bottom combing shaft 2 is rotatably mounted on its inner side, and height adjustment components are provided on both sides. It is also connected to the pulling structure on both sides, forming a crucial framework for connecting the various parts of the device.

[0029] Bottom carding shaft 2: Rotatably mounted on the inner side of the concave bracket 1, with multiple sets of arc-shaped grooves 3 evenly spaced on its outer wall. It corresponds vertically to the top carding shaft 4, working together to card the chemical fibers. During operation, the yarn passes between it and the top carding shaft 4, as well as between it and the side shafts 14 on both sides.

[0030] Arc-shaped grooves 3: are equidistantly formed on the outer wall of the bottom combing shaft 2, and are used to guide and pre-sort the yarn during the combing process, so that the yarn can pass through the bottom combing shaft 2 in an orderly manner, preparing for subsequent combing work.

[0031] Top combing shaft 4: Located between the height adjustment components on both sides, corresponding vertically to the bottom combing shaft 2. Its outer wall has multiple sets of arc-shaped protrusions 5 integrally formed at equal intervals, with the positions of the arc-shaped protrusions 5 and the arc-shaped grooves 3 corresponding to each other. Driven by the motor 9, it rotates, and through the interaction between the arc-shaped protrusions 5 and the arc-shaped grooves 3 of the bottom combing shaft 2, it combs the chemical fibers.

[0032] Arc-shaped protrusions 5: Equivalently spaced and integrally formed on the outer wall of the top carding shaft 4, corresponding to the arc-shaped grooves 3 on the bottom carding shaft 2. When the top carding shaft 4 rotates, it cooperates with the arc-shaped grooves 3 to achieve the carding operation of chemical fibers and help to organize the fiber shape.

[0033] Concave mounting bracket 6: Located on both sides of the concave bracket 1, it is an important component of the height adjustment assembly. A servo cylinder 7 is fixedly mounted on its bottom inner wall, providing a stable mounting base for the servo cylinder 7 and ensuring the stability of the height adjustment process.

[0034] Servo cylinder 7: Fixedly installed on the bottom inner wall of the concave mounting bracket 6, with its output shaft fixedly connected to the L-shaped motor mounting seats 8 on both sides of the top combing shaft 4. When it is necessary to adjust the distance between the top combing shaft 4 and the bottom combing shaft 2, the servo cylinder 7 is activated, and the L-shaped motor mounting seats 8 move up and down through the extension and retraction of the output shaft, thereby adjusting the distance between them to adapt to the combing needs of different types of fibers.

[0035] L-shaped motor mounting bracket 8: Located on both sides of the top combing shaft 4, it has a motor 9 fixedly mounted on it, and its bottom is fixedly connected to the output shaft of the servo cylinder 7. It provides a mounting position for the motor 9 and can drive the motor 9 and the top combing shaft 4 to move up and down under the drive of the servo cylinder 7 to achieve height adjustment.

[0036] Motor 9: Fixedly mounted on L-shaped motor mounting base 8, with its output shaft passing through one side of L-shaped motor mounting base 8 and fixedly connected to the side of top combing shaft 4. Its function is to provide power for the rotation of top combing shaft 4, driving it to perform combing work.

[0037] Side groove 10: It is opened on both sides of the concave bracket 1 at the position corresponding to the pulling structure. A spring 12 is fixedly installed inside it, which provides space for the sliding of the slider 11 and is also the installation place of the spring 12.

[0038] Slider 11: Slidably installed inside the side groove 10, with a concave connecting block 13 fixedly installed at one end extending to the outside of the side groove 10. When the spring 12 returns normally, the slider 11 will fit against the inner wall of the side groove 10, and its sliding will drive the concave connecting block 13 and the side shaft 14 to move.

[0039] Spring 12: Fixedly installed inside the side groove 10, it applies elastic force to the slider 11. During normal rebound, it pushes the slider 11 to fit against the inner wall of the side groove 10, thereby causing the side shaft 14 to fit against the outer wall of the bottom combing shaft 2, ensuring the stability of the side shaft 14 during yarn combing.

[0040] The concave connecting block 13 is U-shaped, with one end fixedly connected to the end of the slider 11 that extends to the outside of the side groove 10, and the other end rotatably connected to the side shaft 14 around one side of the concave bracket 1. It serves to connect the slider 11 and the side shaft 14, transmitting the movement of the slider 11 to the side shaft 14.

[0041] Side shaft 14: Both ends of both sides are rotatably connected to the concave connecting block 13 in the pulling structure. When the spring 12 returns normally, the side shaft 14 is in contact with the outer wall of the bottom combing shaft 2. In use, the yarn is guided through the space between the side shaft 14 and the bottom combing shaft 2 on one side, then between the bottom combing shaft 2 and the top combing shaft 4, and finally between the side shaft 14 and the bottom combing shaft 2 on the other side, thus guiding and assisting in combing the yarn.

[0042] The specific connection method is as follows: It includes a concave bracket 1, a bottom combing shaft 2 is rotatably installed on the inner side of the concave bracket 1, height adjustment components are provided on both sides of the concave bracket 1, and a top combing shaft 4 is provided between the height adjustment components on both sides. The top combing shaft 4 corresponds vertically to the bottom combing shaft 2. When it is necessary to comb the chemical fiber, the limit will pass between the bottom combing shaft 2 and the top combing shaft 4. At the same time, according to the different types of chemical fibers, the vertical height of the top combing shaft 4 is adjusted, and the distance between the top combing shaft 4 and the bottom combing shaft 2 is adjusted.

[0043] Furthermore, multiple sets of arc-shaped grooves 3 are equidistantly formed on the outer wall surface of the bottom combing shaft 2, and multiple sets of arc-shaped protrusions 5 are integrally formed on the outer wall surface of the top combing shaft 4. The positions of the arc-shaped protrusions 5 and the top combing shaft 4 are kept in correspondence. When it is necessary to comb the chemical fibers, it is generally necessary to pre-comb the fibers and then perform fine combing. When using this device, the limiter passes through different arc-shaped grooves 3 in sequence, and then the top combing shaft 4 rotates to comb the chemical fibers, and then guides them into the subsequent fine combing equipment.

[0044] Furthermore, the height adjustment component includes a concave mounting bracket 6 and a servo cylinder 7. The concave mounting bracket 6 is disposed on both sides of the concave support 1. The servo cylinder 7 is fixedly installed on the bottom inner wall of the concave mounting bracket 6. The output shaft of the servo cylinder 7 is connected to the motor structure on both sides of the top combing shaft 4. When it is necessary to adjust the distance between the top combing shaft 4 and the bottom combing shaft 2, the servo cylinder 7 is activated, its output shaft extends and retracts, and then the distance between the top combing shaft 4 and the bottom combing shaft 2 is adjusted.

[0045] Furthermore, the motor structure includes L-shaped motor mounting seats 8 located on both sides of the top combing shaft 4. A motor 9 is fixedly mounted on the L-shaped motor mounting seat 8. The output shaft of the motor 9 passes through one side of the L-shaped motor mounting seat 8 and is fixedly connected to the side of the top combing shaft 4. The bottom of the L-shaped motor mounting seat 8 is fixedly connected to the output shaft of the servo cylinder 7. The motor 9 is used to drive the top combing shaft 4 to rotate.

[0046] Furthermore, side shafts 14 are respectively provided on both sides of the bottom combing shaft 2, and both ends of the side of the side shaft 14 are provided with a pulling structure, and the connecting end of the pulling structure is connected to both sides of the concave bracket 1.

[0047] Furthermore, side grooves 10 are respectively provided on the two sides of the pull structure of the concave bracket 1, and springs 12 are fixedly installed inside the side grooves 10.

[0048] Furthermore, the pulling structure includes a slider 11 and a concave connecting block 13. The slider 11 is slidably installed inside the side groove 10. The concave connecting block 13 is fixedly installed at one end of the slider 11 extending to the outside of the side groove 10. The concave connecting block 13 is U-shaped and is rotatably connected to the side shaft 14 around one side of the concave bracket 1. When the spring 12 rebounds normally, the slider 11 will fit against the inner wall of the side groove 10, while the side shaft 14 fits against the outer wall of the bottom combing shaft 2. During use, the yarn to be combed is guided through the side shaft 14 and the bottom combing shaft 2 on the same side, through the arc groove 3, then through the bottom combing shaft 2 and the top combing shaft 4, and then through the side shaft 14 and the bottom combing shaft 2 on the other side.

[0049] Working principle: When chemical fibers need to be combed, they generally need to be pre-combed before fine combing. When using this device, the limiter passes through different arc-shaped grooves 3 in sequence, and then the top combing shaft 4 rotates to comb the chemical fibers. After that, the fibers are guided into the subsequent fine combing equipment. When the spring 12 returns normally, the slider 11 will be attached to the inner wall of the side groove 10, and the side shaft 14 will be attached to the outer wall of the bottom combing shaft 2. When in use, the yarn to be combed is guided through the side shaft 14 and the bottom combing shaft 2 on the same side, through the arc-shaped groove 3, then through the bottom combing shaft 2 and the top combing shaft 4, and then through the side shaft 14 and the bottom combing shaft 2 on the other side.
