When using the warp knitting machine, the warp knitting machine produces warp knitted fabrics by a method of forming loops on the working needles of a group or a set of parallel arranged yarns by unwinding from a bobbin and stably inputting in the machine in the warp direction, so that the yarns can be well woven into a webbing.
[0028] Refer to Figure 2 and Figure 3, the adjusting device 5 includes a support plate 501. An inner wall of the support plate 501 is fixedly connected with a connecting roller 505. An inner wall of the support plate 501 is fixedly connected with a limiting rod 502. A pressing plate 503 is slidably sleeved on a surface of the limiting rod 502. A first spring 504 is sleeved on the surface of the limiting rod 502. A top of the first spring 504 is fixedly connected with a top of an inner wall of the support plate 501. An end of the first spring 504 close to the limiting rod 502 is fixedly connected with a top of the pressing plate 503. When using the adjusting device 5, set the silk thread on tops of the two connecting rollers 505, and press the pressing plate 503 towards the direction close to the support plate 501 through the first spring 504, so that the pressing plate 503 presses on the silk thread, which can straighten the silk thread, automatically adjust the tension of the silk thread to a certain extent, avoid the silk thread from being wound together when entering the machine interior, and further avoid affecting the working of the warp knitting machine to a certain extent. A support block 506 is fixedly connected to a bottom of the pressing plate 503. A clamping rod 507 is fixedly connected to an inner wall of the support block 506. A roller 508 is rotatably sleeved on a surface of the clamping rod 507. When the pressing plate 503 is arranged on top of the silk thread, the roller 508 presses on top of the silk thread, and thus the roller 508 is driven to roll, so that the silk thread can well pass through a bottom of the pressing plate 503. A limiting groove 509 is formed in one side of an inner wall of the support plate 501. A connecting rod 511 is slidably connected to an inner wall of the limiting groove 509. A moving strip 510 is slidably sleeved on a surface of the connecting rod 511. A second spring 512 is sleeved on the surface of the connecting rod 511. A bottom of the second spring 512 is fixedly connected with a bottom of an inner wall of the limiting groove 509. An end of the second spring 512 close to the connecting rod 511 is fixedly connected with a bottom of the moving strip 510. A rotating rod 513 is fixedly connected to a bottom of the moving strip 510. A cylinder 514 is rotatably sleeved on a surface of the rotating rod 513. Control the moving strip 510 to slide downward on the surface of the connecting rod 511, so that the cylinder 514 presses on tops of the connecting rollers 505. Pull the moving strip 510 downward through the second spring 512, and thus well set the cylinder 514 on tops of the connecting rollers 505, so that the silk thread can be well set on tops of the connecting rollers 505. A limiting frame 515 is fixedly connected to a top of the moving strip 510. A first threaded rod 516 is rotatably inserted through one side of the limiting frame 515. An L-shaped plate 517 is threadedly sleeved on a surface of the first threaded rod 516. The L-shaped plate 517 is slidably connected to an inner wall of the limiting frame 515. Thread directions on surfaces of the first threaded rod 516 are opposite from the middle to both sides. Manually rotate the first threaded rod 516. Because the thread directions on surfaces of the first threaded rod 516 are opposite from the middle to both sides, the L-shaped plate 517 threadedly sleeved on the surface of the first threaded rod 516 can move relatively inside the limiting frame 515, and thus the silk thread can be restricted on tops of the connecting rollers 505 through the L-shaped plate 517.
[0029] Refer to Figure 4, the mobile device 6 includes a first sliding frame 601, and the first sliding frame 601 is fixedly connected to the bottom of the inner wall of the support frame 1. The inner wall of the first sliding frame 601 is slidably connected to the connecting frame 7. When using the mobile device 6, manually control the connecting frame 7 to slide on the inner wall of the first sliding frame 601, so that the connecting frame 7 is far away from the support frame 1. In this way, a bobbin with a silk thread wound on its surface can be well placed on the connecting frame 7. A second threaded rod 602 is rotatably inserted through one side of the first sliding frame 601, and the second threaded rod 602 is threadedly inserted through one side of the connecting frame 7. Manually control the rotation of the second threaded rod 602, and then the sliding of the connecting frame 7 on the inner wall of the first sliding frame 601 can be well controlled. A second sliding frame 603 is fixedly connected to the top of the inner wall of the support frame 1. The inner wall of the second sliding frame 603 is slidably connected to the connecting frame 7. A round rod 604 is fixedly connected to the inner wall of the second sliding frame 603, and the round rod 604 is slidably inserted through one side of the connecting frame 7. When the connecting frame 7 moves inside the support frame 1, the connecting frame 7 is restricted inside the second sliding frame 603 through the round rod 604. A receiving groove 605 is formed on one side of the connecting frame 7, and a rectangular strip 606 is slidably connected to the inner wall of the receiving groove 605. A damping rod 607 is fixedly connected to one side of the inner wall of the receiving groove 605. One end of the damping rod 607 away from the receiving groove 605 is fixedly connected to one side of the rectangular strip 606. A third spring 608 is sleeved on the surface of the damping rod 607. One end of the third spring 608 is fixedly connected to one side of the inner wall of the receiving groove 605, and one end of the third spring 608 close to the damping rod 607 is fixedly connected to one end of the rectangular strip 606. After the bobbin with the silk thread wound on it is sleeved on the connecting frame 7 and the rectangular strip 606 is close to one side of the connecting frame 7, the rectangular strip 606 is squeezed away from the receiving groove 605 by the third spring 608, so that the bobbin can be well restricted on the connecting frame 7.
[0030] Working principle: When using a warp knitting machine, the warp knitting machine forms warp knitted fabric by a method of forming loops on the working needles of the machine through a group or a set of parallel arranged yarns. The yarns are fed from the creel and stably input in the warp direction. In this way, the yarns can be well knitted into a webbing (the warp knitting machine has long been on the market, so it will not be elaborated here). When using the adjusting device 5, the silk thread is set on the top of the two connecting rollers 505. Control the moving strip 510 to slide downward on the surface of the connecting rod 511, so that the cylinder 514 is pressed against the top of the connecting roller 505. Pull the moving strip 510 downward through the second spring 512, so that the cylinder 514 is well set on the top of the connecting roller 505. In this way, the silk thread can be well set on the top of the connecting roller 505. Squeeze the pressing plate 503 in the direction close to the support plate 501 through the first spring 504, so that the pressing plate 503 presses on the silk thread. When the pressing plate 503 is set on the top of the silk thread, the roller 508 presses on the top of the silk thread, so that the roller 508 is driven to roll, so that the silk thread can well pass through the bottom of the pressing plate 503. In this way, the silk thread can be straightened, and the tension of the silk thread can be automatically adjusted to a certain extent, avoiding the silk thread from being wound together when entering the machine interior, and thus avoiding affecting the operation of the warp knitting machine to a certain extent. Among them, manually rotate the first threaded rod 516. Because the thread direction on the surface of the first threaded rod 516 is opposite from the middle to both sides, the L-shaped plate 517 sleeved on the thread of the first threaded rod 516 can move relative to each other inside the limit frame 515. In this way, the silk thread can be restricted on the top of the connecting roller 505 through the L-shaped plate 517. When using the moving device 6, manually control the second threaded rod 602 to rotate, so that the connecting frame 7 can be well controlled to slide on the inner wall of the first sliding frame 601, so that the connecting frame 7 moves away from the support frame 1. When the connecting frame 7 moves inside the support frame 1, the connecting frame 7 is restricted inside the second sliding frame 603 through the round rod 604. After the bobbin wound with the silk thread is sleeved on the rectangular strip 606 on the side close to the connecting frame 7, the rectangular strip 606 is squeezed in the direction away from the receiving groove 605 through the third spring 608. In this way, the bobbin can be well restricted on the connecting frame 7, and the bobbin with the silk thread wound on the surface can be well set on the connecting frame 7.
