[0002] A silk knitting circular knitting machine is a textile machine specialized for producing silk knitted fabrics. It weaves silk yarns into a cylindrical fabric through multiple looping systems. It has the characteristics of being applicable to silk yarns, high-precision knitting, and efficient production, and is widely used in fields such as clothing manufacturing and household items. It can achieve complex patterns and meet different design requirements.
[0003] The yarn feeding device of a silk knitting circular knitting machine is used to accurately feed silk yarns. When in use, the yarn bobbin is placed on the yarn rack, and the yarn passes through a guide device and enters the circular knitting machine, which can reduce yarn breakage and faults, improve production efficiency, ensure the quality of the fabric, provide a stable and reliable yarn supply for silk knitting production, and meet different knitting process requirements.
[0004] However, the existing yarn feeding device of a silk knitting circular knitting machine cannot adjust the tension of the yarn during use, so that the silk yarn often becomes too tight or loose during the conveying process. When the yarn is too tight, it is easy to cause the yarn to break, affecting production efficiency, while the loose yarn will make the density of the fabric uneven, seriously affecting the quality and appearance of the silk fabric. Based on the above problems, a yarn feeding device for a silk knitting circular knitting machine is proposed. Summary of the Utility Model

[0023] Refer to Figures 1-6, A silk knitting circular machine yarn feeding device, including a top plate 1, a through hole 2 is provided on the surface of the top plate 1, a first connecting rod 3 and a second connecting rod 4 are fixedly arranged at the bottom of the top plate 1, a first support plate 5 is fixedly arranged at the bottom of the first connecting rod 3, a second support plate 6 is fixedly arranged at the bottom of the second connecting rod 4, a mounting frame 17 is fixedly arranged at the top of the first support plate 5, a mounting shaft 18 is rotatably arranged inside the mounting frame 17, a yarn guiding ring 19 is fixedly arranged at the top end of the mounting shaft 18, a guide 16 is fixedly arranged inside the second support plate 6, a driving component is arranged at the top of the first support plate 5, the driving component includes a driving motor 7 fixedly arranged at the top of the first support plate 5, the output end of the driving motor 7 is fixedly provided with a main shaft 8, the surface of the main shaft 8 is fixedly connected with a rotating plate 9, starting the driving motor 7 makes the main shaft 8 rotate to drive the rotating plate 9 to rotate, and then multiple yarn guiding rollers 11 can be moved, so as to adjust the tension of multiple batches of silk yarns. The first support plate 5 is provided with a rotating plate 9 through the driving component. A rotating shaft 10 is rotatably arranged inside the rotating plate 9, and yarn guiding rollers 11 are fixedly arranged on the surface of the rotating shaft 10. The yarn guiding ring 19 and the yarn guiding rollers 11 are made of the same material, which is stainless steel material with a smooth surface. The smooth yarn guiding ring 19 and yarn guiding rollers 11 can effectively reduce the friction with the silk yarns and reduce the wear of the silk yarns. A rotating component is arranged at the bottom of the rotating plate 9. For this silk knitting circular machine yarn feeding device, starting the driving motor 7 drives the main shaft 8 to rotate, the main shaft 8 rotates to drive the rotating plate 9 to rotate, the rotating plate 9 rotates to drive the yarn guiding rollers 11 at its top to move through the rotating shaft 10, the movement of the yarn guiding rollers 11 drives the silk yarns on their surfaces to move, and the tension of the silk yarns is adjusted. At the same time, the movement of the silk yarns makes the yarn guiding ring 19 rotate, and the rotation of the yarn guiding ring 19 makes the mounting shaft 18 rotate inside the mounting frame 17, avoiding the silk yarns from squeezing the edge of the yarn guiding ring 19. This device can adjust the tension of the silk yarns, and can effectively avoid the situation that the silk yarns are too tight and break or are too loose and uneven during the conveying process, thereby improving the production quality of silk fabrics.
[0024] Specifically, the rotating component includes a bracket 15 fixedly arranged at the bottom of the rotating plate 9, a rotating motor 14 is fixedly arranged inside the bracket 15, the output end of the rotating motor 14 is fixedly provided with a driving gear 13, a driven gear 12 is meshed on the surface of the driving gear 13, the number of the driven gears 12 is multiple, and the multiple driven gears 12 are distributed in a circular array. The driven gear 12 is fixedly connected with the rotating shaft 10. Starting the rotating motor 14 drives the driving gear 13 to rotate, the driving gear 13 rotates to drive the driven gear 12 to rotate, and the rotation of the driven gear 12 drives the yarn guiding roller 11 to rotate through the rotating shaft 10 to assist the movement of the silk yarns. When the silk yarns slide on the surface of the yarn guiding roller 11, the rotation of the yarn guiding roller 11 can reduce the static friction between the silk yarns and the yarn guiding roller 11, avoiding damage or jamming of the silk yarns due to excessive friction.
[0025] Specifically, fixing blocks 20 are fixedly arranged on the surface of the top plate 1. The number of the fixing blocks 20 is multiple, and the multiple fixing blocks 20 are distributed in a circular array. Fixing holes 21 are formed inside the fixing blocks 20.

[0026] The electrical components appearing in this article are all electrically connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.
[0027] During use: Feed the silk yarn into the device through a yarn guide, and it passes through the through hole 2, the yarn guide ring 19, and the surface of the yarn guide roller 11 in sequence. Finally, the silk yarn is fed to a circular knitting machine through the guide 16. When it is necessary to adjust the tension of the yarn, start the drive motor 7 to drive the main shaft 8 to rotate. The rotation of the main shaft 8 drives the rotating plate 9 to rotate. The rotation of the rotating plate 9 drives the yarn guide roller 11 at its top to move through the rotating shaft 10. The movement of the yarn guide roller 11 drives the silk yarn on its surface to move, thereby adjusting the tension of the silk yarn. At the same time, the movement of the silk yarn causes the yarn guide ring 19 to rotate, and the rotation of the yarn guide ring 19 causes the mounting shaft 18 to rotate inside the mounting frame 17. During the conveying process of the silk yarn, start the rotating motor 14 to drive the driving gear 13 to rotate. The rotation of the driving gear 13 drives the driven gear 12 to rotate. The rotation of the driven gear 12 drives the yarn guide roller 11 to rotate through the rotating shaft 10 to assist the movement of the silk yarn.
[0028] To sum up, for this silk circular knitting machine yarn feeding device, start the drive motor 7 to drive the main shaft 8 to rotate. The rotation of the main shaft 8 drives the rotating plate 9 to rotate. The rotation of the rotating plate 9 drives the yarn guide roller 11 at its top to move through the rotating shaft 10. The movement of the yarn guide roller 11 drives the silk yarn on its surface to move, thereby adjusting the tension of the silk yarn. At the same time, the movement of the silk yarn causes the yarn guide ring 19 to rotate, and the rotation of the yarn guide ring 19 causes the mounting shaft 18 to rotate inside the mounting frame 17, avoiding the silk yarn from being squeezed at the edge of the yarn guide ring 19. This device can adjust the tension of the silk yarn, effectively avoiding the situation that the silk yarn breaks due to being too tight or becomes uneven due to slack during the conveying process, thereby improving the production quality of silk fabrics.
