[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 This utility model provides a technical solution:
[0026] A yarn feeding device for multi-colored yarns in flyknit fabrics includes a yarn feeding disc 1, which is circular. The yarn feeding disc 1 has evenly distributed yarn feeding openings 2. Evenly distributed collars 3 are arranged on one side of the yarn feeding disc 1. The number of sets of collars 3 is the same as the number of sets of yarn feeding openings 2, and the inner diameter of the collars 3 is adapted to the size of the yarn feeding openings 2. The collars 3 are directly opposite the yarn feeding openings 2. An electric push rod 4 is fixedly installed on the side of the yarn feeding disc 1 away from the collars 3. A drive column 5 is provided, which is shaped like a frustum. The output shaft end of the electric push rod 4 is fixedly installed to the end of the drive column 5. Movable columns 6 are fixedly installed on the side of the collar 3. The end of the movable column 6 near the drive column 5 is set as an arc surface, and the end of the movable column 6 is in contact with the side of the drive column 5. Springs 7 are evenly distributed and fixedly installed on the wire feeding reel 1. The number of sets of springs 7 is the same as the number of sets of movable columns 6, and the springs 7 are pressed between the wire feeding reel 1 and the movable columns 6.
[0027] During the yarn feeding process of the flyknitted fabric, multiple groups of yarns of different colors pass through the loop 3 and the feeding port 2 of the yarn feeding disc 1 to guide the yarn. The loop 3 and the feeding port 2 limit the yarn to ensure the stability of the yarn.
[0028] When it is necessary to adjust the tension of multiple sets of yarns simultaneously, the electric push rod 4 on the side of the feed plate 1 is activated. The output shaft of the electric push rod 4 drives the frustum-shaped drive column 5 fixed thereto to move. Since the end of the movable column 6 near the drive column 5 is arc-shaped and fits against the side of the drive column 5, the drive column 5 moves while squeezing multiple sets of movable columns 6. The movable column 6 overcomes the elastic force of the spring 7 and drives the collar 3 to move, thereby synchronously changing the angle between multiple sets of collar 3 and the feed port 2, so as to realize the synchronous adjustment of the tension of multiple sets of multi-color yarns.
[0029] This multi-color yarn feeding device for flyknitted fabrics can simultaneously adjust the tension of multiple sets of multi-color yarns, ensuring the uniformity and consistency of yarn tension, significantly improving the finished quality of flyknitted fabrics, and is highly practical.
[0030] The edge of the wire feed reel 1 is fixedly equipped with evenly distributed limiting frames 8. The number of sets of the limiting frames 8 is the same as the number of sets of the collar 3. Each side of the collar 3 is fixedly equipped with a connecting rod 9. Each end of the connecting rod 9 is fixedly equipped with a limiting block 10. The limiting block 10 is slidably arranged on the limiting frame 8.
[0031] When the collar 3 moves horizontally under the drive of the movable column 6, the connecting rod 9 on the side of the collar 3 will move together with the collar 3. The limiting block 10 at the end of the connecting rod 9 will slide synchronously within the limiting frame 8. The limiting frame 8 restricts the movement trajectory of the limiting block 10, so that the collar 3 always maintains stable horizontal movement, avoiding the collar 3 from shifting or shaking during the adjustment process, thereby further ensuring the stability of the tension adjustment of the multi-color yarn.
[0032] The limiting frame 8 is located on the side of the limiting block 10 and has a scale.
[0033] The limiting frame 8 is located on the side of the limiting block 10 and has a scale. The operator can observe the scale value aligned with the edge of the limiting block 10 to intuitively understand the specific displacement of the collar 3, thereby accurately judging the adjustment range of the yarn tension.
[0034] Both sides of the wire feeding port 2 and the collar 3 are set as arc edges;
[0035] Both sides of the feed port 2 and the collar 3 are set as arc edges. The arc edges can effectively reduce the frictional resistance when the yarn comes into contact with the edge, thus protecting it during the yarn conveying process.
[0036] The feeding port 2, the collar 3, and the movable column 6 are provided with at least four evenly distributed sets;
[0037] The feeding port 2, the collar 3, and the movable column 6 are provided with at least four evenly distributed sets, so that the device can guide at least four sets of yarns at the same time, which meets the need for feeding multiple sets of yarns at the same time when weaving multi-color flyknitted fabrics.
[0038] A controller is provided on one side of the electric push rod 4 for the wire feeding reel 1, and the controller is electrically connected to the electric push rod 4;
[0039] The wire feed reel 1 is equipped with a controller on one side of the electric push rod 4. The controller is electrically connected to the electric push rod 4. The operator can send adjustment commands through the controller. The controller will convert the commands into electrical signals and transmit them to the electric push rod 4. After receiving the signal, the electric push rod 4 will start and drive the drive column 5 to move, thereby realizing the automatic adjustment of the collar 3, which improves the convenience and automation of adjustment.
[0040] Working principle:
[0041] During the yarn feeding process of the flyknitted fabric, multiple groups of yarns of different colors pass through the loop 3 and the feeding port 2 of the yarn feeding disc 1 to guide the yarn. The loop 3 and the feeding port 2 limit the yarn to ensure the stability of the yarn.
[0042] When it is necessary to adjust the tension of multiple sets of yarns simultaneously, the electric push rod 4 on the side of the feed plate 1 is activated. The output shaft of the electric push rod 4 drives the frustum-shaped drive column 5 fixed thereto to move. Since the end of the movable column 6 near the drive column 5 is arc-shaped and fits against the side of the drive column 5, the drive column 5 moves while squeezing multiple sets of movable columns 6. The movable column 6 overcomes the elastic force of the spring 7 and drives the collar 3 to move, thereby synchronously changing the angle between multiple sets of collar 3 and the feed port 2, so as to realize the synchronous adjustment of the tension of multiple sets of multi-color yarns.
[0043] When the collar 3 moves horizontally under the drive of the movable column 6, the connecting rod 9 on the side of the collar 3 will move together with the collar 3. The limiting block 10 at the end of the connecting rod 9 will slide synchronously within the limiting frame 8. The limiting frame 8 restricts the movement trajectory of the limiting block 10, so that the collar 3 always maintains stable horizontal movement, avoiding the collar 3 from shifting or shaking during the adjustment process, thereby further ensuring the stability of the multi-color yarn tension adjustment.
[0044] This multi-color yarn feeding device for flyknitted fabrics can simultaneously adjust the tension of multiple sets of multi-color yarns, ensuring the uniformity and consistency of yarn tension, significantly improving the finished quality of flyknitted fabrics, and is highly practical.
[0045] in,
[0046] The limiting frame 8 is set with scale on the side of the limiting block 10. The operator can intuitively understand the specific displacement of the collar 3 by observing the scale value aligned with the edge of the limiting block 10, so as to accurately judge the adjustment range of the yarn tension.
[0047] Both sides of the feed port 2 and the collar 3 are set as arc edges. The arc edges can effectively reduce the frictional resistance when the yarn comes into contact with the edge, thus protecting the yarn during the yarn conveying process.
[0048] The feeding port 2, the collar 3, and the movable column 6 are provided with at least four evenly distributed sets, so that the device can guide at least four sets of yarns at the same time, which meets the need for feeding multiple sets of yarns at the same time when weaving multi-color flyknitted fabrics.
[0049] The wire feed reel 1 is equipped with a controller on one side of the electric push rod 4. The controller is electrically connected to the electric push rod 4. The operator can send adjustment commands through the controller. The controller will convert the commands into electrical signals and transmit them to the electric push rod 4. After receiving the signal, the electric push rod 4 will start and drive the drive column 5 to move, thereby realizing the automatic adjustment of the collar 3, which improves the convenience and automation of adjustment.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
