Description

Technical Field

[0001] This utility model belongs to the field of air-jet spinning technology, specifically relating to a yarn bobbin transmission and correction mechanism. Background Technology

[0002] Air-jet spinning is an innovative method widely used in the textile industry. It precisely stretches cotton slivers and transforms them into yarn through a cleverly designed airflow within the spinning cup. Compared to traditional ring spinning, air-jet spinning significantly improves production efficiency, reduces energy consumption, and its unique yarn structure gives it remarkable advantages in numerous applications, bringing new vitality and development opportunities to the textile industry.

[0003] In the prior art, the conveying device for air-jet spun yarn uses a rotatable yarn bobbin to transport the yarn. The vibration generated when the yarn bobbin rotates makes the yarn prone to horizontal swaying on the surface of the yarn bobbin during the conveying process, which causes the yarn conveying path to deviate. At the same time, this swaying will increase the friction surface between the yarn and the yarn bobbin, which will lead to the risk of yarn breakage. Utility Model Content

[0004] In view of this, the present invention provides a yarn bobbin conveying correction mechanism, the purpose of which is to reduce the movable range of the yarn during the conveying process in order to correct the yarn conveying path.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A yarn bobbin transmission and correction mechanism includes a correction plate and a guide wheel. The correction plate has a guide groove for guiding the yarn, which extends along the length of the correction plate. The correction plate has fixing frames on both sides for connecting the guide wheel. The tops of the two fixing frames are arranged opposite each other along the width of the correction plate. The guide wheel is rotatably connected between the bottom ends of the two fixing frames. The guide wheel has a retaining ring, and the two retaining rings are distributed opposite each other on the guide wheel to form a groove.

[0007] As a preferred technical solution, the retaining ring has a conical structure, and the side of the two retaining rings facing each other is a conical surface.

[0008] Furthermore, the calibration plate is also provided with an adjustment assembly for adjusting the tension of the guide wheel. The adjustment assembly includes a moving rod and a connecting frame. The two moving rods are horizontally arranged on both sides of the calibration plate, and one end of the two moving rods is connected to two fixed frames respectively. The connecting frame is connected between the other ends of the two moving rods, and the connecting frame is externally connected to a telescopic component.

[0009] Furthermore, a guide post is provided between the connecting frame and the correction plate, wherein one end of the guide post is fixed on the correction plate and the other end of the guide post passes through the connecting frame.

[0010] Furthermore, the correction plate has a groove extending along the length of the correction plate on the side facing the fixing frame, and the top of the fixing frame has a slide rod adapted to the groove.

[0011] Furthermore, the correction plate is provided with a limiting member for supporting the moving rod, the limiting member including a limiting sleeve, the limiting sleeve being sleeved on the moving rod.

[0012] Furthermore, the surface of the movable rod is arrayed with several beaded balls, and the inner wall of the limiting sleeve is provided with holes that are adapted to the beaded balls.

[0013] Furthermore, the calibration plate is provided with several mounting holes.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In existing technologies, air-jet spun yarn conveying devices support and transport the yarn using yarn bobbins. However, the vibration generated during the rotation of the yarn bobbin can easily cause the yarn to oscillate horizontally on the roller surface during conveying, leading to a deviation in the yarn conveying path. Furthermore, this oscillation increases the frictional area between the yarn and the yarn bobbin, thereby increasing the risk of yarn breakage.

[0024] Example 1

[0025] Therefore, in order to solve the above problems and realize the functions of reducing the movable range of yarn during the conveying process and correcting the yarn conveying path, this utility model discloses a yarn bobbin conveying correction mechanism, see reference. Figure 1 and Figure 2 The system includes a correction plate 1 and a guide wheel 7. The correction plate 1 has a guide wire groove 2 for guiding the yarn. The guide wire groove 2 extends along the length of the correction plate 1. The correction plate 1 has fixing frames 5 on both sides for connecting the guide wheel 7. The tops of the two fixing frames 5 are arranged opposite each other along the width of the correction plate 1. The guide wheel 7 is rotatably connected between the bottom ends of the two fixing frames 5. The guide wheel 7 has a retaining ring 12. The two retaining rings 12 are distributed opposite each other on the guide wheel 7 to form a slot 13.

[0026] In this embodiment, the yarn conveying path is corrected by the cooperation of the wire groove 2 and the card slot 13, in order to reduce the swaying amplitude of the yarn and reduce its friction area with the yarn bobbin.

[0027] For example, before the conveying begins, the end of the yarn generated in the spinning cup is passed through the guide groove 2 so that the yarn can fit into the slot 13. Then, the yarn is continuously stretched and wound onto the yarn bobbin. Next, the conveying device is started so that the yarn bobbin rotates to convey the yarn. At this time, the horizontal movement range of the yarn is limited to the width of the guide groove 2 so that the yarn does not sway in a large range. The slot 13 further ensures that the yarn remains stable during the conveying process and prevents the yarn from falling off the guide wheel 7. As the yarn bobbin continues to rotate, the yarn is evenly wound on the surface of the yarn bobbin, thereby achieving precise correction of the yarn conveying path.

[0028] This method makes yarn transport smoother, reduces yarn damage caused by friction and shaking, and improves yarn quality and production efficiency.

[0029] In addition, as the yarn bobbin rotates, the stretched yarn drives the guide wheel 7 to rotate. The rotating guide wheel 7 helps to increase the tension on the yarn, so that the yarn can be tightened and further reduce the deviation of the yarn during the conveying process.

[0030] As a preferred technical solution, the retaining ring 12 has a conical structure, and the side of the two retaining rings 12 facing each other is a conical surface. With this arrangement, the yarn can enter the slot 13 more easily. At the same time, during the yarn feeding process, the conical structure can better adapt to the tension changes of the yarn, which helps to concentrate the stress of the yarn on the guide wheel 7, thereby reducing the friction between the yarn and the retaining ring 12, further ensuring the stability of the yarn in the slot 13, and preventing the yarn from slipping out from the edge of the slot 13.

[0031] In this embodiment, the correction plate 1 is provided with a number of mounting holes. Through these mounting holes, the correction plate 1 can be easily installed on an air-jet spinning machine or other related equipment to ensure the stable installation of the entire yarn bobbin transmission correction mechanism. The mounting holes may be provided with threads so that they can be externally connected to the air-jet spinning machine by screws.

[0032] Example 2

[0033] Based on Example 1, in order to improve the effect of yarn tension adjustment, please refer to... Figures 1-2 The correction plate 1 is also provided with an adjustment assembly for adjusting the tension of the guide wheel 7. Specifically, the adjustment assembly includes a moving rod 4 and a connecting frame 9. The two moving rods 4 are horizontally positioned opposite each other on both sides of the correction plate 1, and one end of each moving rod 4 is connected to two fixed frames 5 respectively. The connecting frame 9 is connected between the other ends of the two moving rods 4 and has an external telescopic component attached to it.

[0034] In this embodiment, the telescopic component includes a telescopic cylinder or an electric push rod. The telescopic movement of the component drives the connecting frame 9 to move horizontally, which in turn drives the moving rod 4 to move along the length of the correction plate 1. This pushes and pulls the fixed frame 5, thereby adjusting the position of the guide wheel 7 and changing the wrap angle of the yarn on the guide wheel 7 to regulate the yarn tension. For example, when increasing the yarn tension, the telescopic component extends, moving the guide wheel 7 forward, increasing the wrap angle of the yarn on the guide wheel 7, and thus increasing the tension. Conversely, when decreasing the yarn tension, the telescopic component shortens, moving the guide wheel 7 backward, decreasing the wrap angle of the yarn, and thus reducing the tension.

[0035] Example 3

[0036] Based on Embodiment 2, in order to improve the stability of the adjustment component during movement, refer to... Figure 1 A guide post 10 is provided between the connecting frame 9 and the correction plate 1, wherein one end of the guide post 10 is fixed on the correction plate 1, and the other end of the guide post 10 passes through the connecting frame 9.

[0037] In this embodiment, the guide post 10 ensures that the connecting frame 9 remains stable during horizontal movement, preventing it from shifting or wobbling, thereby ensuring the accuracy of the guide wheel 7's adjustment position and making the yarn tension adjustment more precise.

[0038] Meanwhile, the correction plate 1 has a groove 8 extending along its length on the side facing the fixing frame 5, and the top of the fixing frame 5 has a sliding rod 11 that matches the groove 8. With this arrangement, when the moving rod 4 moves the fixing frame 5, the sliding rod 11 slides in the groove 8, which not only guides the movement of the fixing frame 5 but also enhances the stability of the movement of the fixing frame 5.

[0039] As a preferred technical solution, the slide 8 is a dovetail groove structure, and the slide rod 11 is a dovetail-shaped structure that is adapted to the slide 8. This structure can improve the tightness of the connection between the fixing frame 5 and the correction plate 1, and help to avoid the situation where the fixing frame 5 and the correction plate 1 become loose in the natural state.

[0040] In addition, the correction plate 1 is provided with a limiting member for supporting the moving rod 4. The limiting member includes a limiting sleeve 3, which is sleeved on the moving rod 4. The surface of the moving rod 4 is arrayed with a plurality of ball bearings 6, and the inner wall of the limiting sleeve 3 is provided with holes that are adapted to the ball bearings 6.

[0041] With this setup, when the telescopic component is activated and the moving rod 4 moves, the abutment 6 will contract due to the compression of the inner wall of the limiting sleeve 3. When the moving rod 4 moves to the appropriate position, the abutment 6 will pop out and lock into the hole in the inner wall of the limiting sleeve 3 to fix the position of the moving rod 4 and prevent the moving rod 4 from moving unexpectedly in its natural state. This improves the support effect on the fixing frame 5 and the guide wheel 7, and further ensures the stability of the yarn tension.

[0042] It should be noted that a ball-bending device typically consists of a bead, a spring, and a casing. The bead is generally spherical and can move freely within the casing, while the spring provides elasticity to keep the bead in a specific position or state. This is existing technology and will not be elaborated further below.

[0043] In summary, based on Embodiments 1 to 3, the working steps of the yarn bobbin transmission correction mechanism are as follows: First, the correction plate 1 is installed through the mounting hole between the spinning cup and the conveying device of the air-jet spinning machine; then, according to actual production needs, the position of the guide wheel 7 is adjusted using the adjustment component to determine the appropriate yarn tension, and the moving rod 4 is supported by the limiting component to prevent the moving rod 4 from moving naturally; next, one end of the yarn generated in the spinning cup is passed through the guide groove 2 so that the yarn fits against the slot 13; then, the yarn is continuously stretched and wound onto the yarn bobbin of the conveying device; finally, the conveying device is started, the yarn bobbin rotates to convey the yarn, and the yarn is stably conveyed along the predetermined path under the combined action of the guide groove 2 and the slot 13, while the guide wheel 7 rotates as the yarn is stretched to maintain the yarn tension, achieving efficient and stable yarn transmission.
