[0046] Example 1:
[0047] Please see Figure 1 - Figure 7 As shown, this embodiment provides a yarn feeding device for a computerized flat knitting machine, including a yarn guiding device 1, and further comprising:
[0048] The first support 2 is fixedly connected to the yarn guiding device 1, and the first guide roller 3 is rotatably connected to the inner wall of the first support 2.
[0049] The first chute 4 is opened inside the yarn guiding device 1 and is connected to the outside. The first slider 5 is slidably connected inside the first chute 4. One end of the first slider 5 is fixedly connected to the second bracket 6. The second guide roller 7 is rotatably connected to the inner wall of the second bracket 6.
[0050] The fixing plate 8 is fixedly connected to the yarn guiding device 1 and located above the second bracket 6. The bottom surface of the fixing plate 8 is provided with a first movable groove 9. Two fixing blocks 10 fixed to the top surface of the second bracket 6 are provided in the first movable groove 9. Two second sliders 11 are slidably connected in the first movable groove 9. Two transmission plates 12 are rotatably connected between the two second sliders 11 and the two fixing blocks 10 respectively.
[0051] The drive assembly is located inside the fixed plate 8 and is used to drive the two second sliders 11 to slide.
[0052] Example 2:
[0053] This embodiment provides a yarn feeding device for a computerized flat knitting machine. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including a driving component comprising:
[0054] The second movable groove 13 is opened in the fixed plate 8 and communicates with the first movable groove 9. Two racks 14 are slidably connected in the second movable groove 13. Two transmission blocks 15 are fixedly connected to the bottom surfaces of the two racks 14 respectively, and one end of the two transmission blocks 15 extends into the first movable groove 9 and is fixed to the top surfaces of the two second sliders 11 respectively. A gear 16 meshes between the two racks 14, and the gear 16 is located on the inner wall of the second movable groove 13 and is rotatably connected to the second movable groove 13.
[0055] The second slide groove 17 is formed on the inner wall of the second movable groove 13. A third slider 18 is slidably connected in the second slide groove 17, and one end of the third slider 18 extends into the second movable groove 13 and is fixed to one of the racks 14. A first threaded rod 19 is threadedly connected in the third slider 18. A rotating rod 20 is fixedly connected to one end of the first threaded rod 19, and one end of the rotating rod 20 passes through the inner wall of the second slide groove 17 and extends to the outside to be rotatably connected to the fixed plate 8.
[0056] A fixing component is located inside the rotating rod 20 and is used to fix the rotating rod 20.
[0057] In operation, the user manually rotates the rotating rod 20, causing the first threaded rod 19 to rotate within the second slide groove 17. This causes the third slider 18 to move along the second slide groove 17 due to the thread action of the first threaded rod 19. One end of the third slider 18 then drives one of the racks 14 to slide within the second movable groove 13. This causes one rack 14 to move through the gear 16, moving the other rack 14 closer to or further away from each other. When the two racks 14 move closer to or further away from each other, they will respectively drive the two transmission blocks 15 to move closer to or further away from each other. This, in turn, causes the two transmission blocks 15 to move the two second sliders 11 closer to or further away from each other, ensuring that the user can control the two second sliders 11 to move closer to or further away from each other.
[0058] Example 3:
[0059] This embodiment provides a yarn feeding device for a computerized flat knitting machine. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including a fixing component:
[0060] The third slide groove 21 is formed inside the rotating rod 20 and is connected to the outside. A fourth slider 22 is slidably connected inside the third slide groove 21. A second threaded rod 23 is threadedly connected inside the fourth slider 22. One end of the second threaded rod 23 passes through the inner wall of the third slide groove 21 and extends to the outside to be rotatably connected to the rotating rod 20. Both ends of the fourth slider 22 are fixedly connected to pressing blocks 24, and the pressing blocks 24 are located on the periphery of the rotating rod 20.
[0061] In use, the user manually rotates the second threaded rod 23, causing the fourth slider 22 to move along the third slide groove 21 under the action of the thread of the second threaded rod 23. This causes the fourth slider 22 to drive the pressing block 24 to move towards the fixed plate 8. When the pressing block 24 moves to a position where it cannot move, the pressing block 24 will press tightly against the fixed plate 8, fixing the rotating rod 20 inside the fixed plate 8 and preventing it from rotating, thus ensuring that the rotating rod 20 will not be affected by external factors.
[0062] Example 4:
[0063] This embodiment provides a computerized flat knitting machine yarn feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the extrusion block 24 is slidably connected to the circumferential side of the rotating rod 20.
[0064] This ensures that the extrusion block 24 can slide normally on the circumference of the rotating rod 20.
[0065] Example 5:
[0066] This embodiment provides a computer flat knitting machine yarn feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: one end of each of the two transmission blocks 15 is slidably connected to the first movable groove 9.
[0067] Specifically, it is ensured that when the two transmission blocks 15 rotate, one end of the two transmission blocks 15 can slide within the first movable groove 9.
[0068] Example 6:
[0069] This embodiment provides a computerized flat knitting machine yarn feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the gear 16 is located on the inner wall of the second movable groove 13 and is rotatably connected to the inner wall of the second movable groove 13.
[0070] This ensures that gear 16 can rotate normally within the second movable groove 13.
[0071] Example 7:
[0072] This embodiment provides a computer flat knitting machine yarn feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: one end of the third slider 18 is slidably connected to the second movable groove 13.
[0073] Specifically, it is ensured that when the third slider 18 slides, one end of the third slider 18 can slide normally within the second movable groove 13.
[0074] In use, the user passes the yarn through the second guide roller 7 from below and the first guide roller 3 from above. The user then manually rotates the rotating rod 20, causing the first threaded rod 19 to rotate within the second slide groove 17. This causes the third slider 18 to move along the second slide groove 17 due to the thread action of the first threaded rod 19. One end of the third slider 18 drives one of the racks 14 to slide within the second movable groove 13. This causes one rack 14 to move through the gear 16, moving the other rack 14 closer to or further apart. When the two racks 14 move closer or further apart, they respectively drive the two transmission blocks 15 to move closer or further apart, causing the two transmission blocks 15 to move the two second sliders 11 closer or further apart. This allows the user to control the movement of the two second sliders 11. When the two second sliders 11 move further apart, they are respectively driven by the two transmission plates. 12 drives the two fixed blocks 10 to move downwards, causing the two fixed blocks 10 to drive the second bracket 6 to move downwards, causing the second bracket 6 to drive the second guide roller 7 to move downwards. When the second bracket 6 moves downwards, it will drive the first slider 5 to slide within the first slide groove 4. When the second guide roller 7 moves downwards, it will press the yarn down. When the second guide roller 7 moves downwards to the appropriate position, the first guide roller 3 and the second guide roller 7 will straighten the yarn, ensuring that the user can adjust the yarn tension. Then, the user manually rotates the second threaded rod 23, causing the fourth slider 22 to be acted upon by the thread of the second threaded rod 23 and move along the third slide groove 21. This causes the fourth slider 22 to drive the extrusion block 24 to move towards the fixed plate 8. When the extrusion block 24 moves to a position where it cannot move, it will press tightly against the fixed plate 8, fixing the rotating rod 20 within the fixed plate 8 and preventing it from rotating, ensuring that the rotating rod 20 will not be affected by external factors.
[0075] The embodiments of this application have been described above with reference to the accompanying drawings.
