[0001] This utility model relates to the field of warp knitting machine technology, and in particular to a warp knitting machine fabric tension adjustment device. Background Technology

[0002] A warp knitting machine is a textile machine that feeds parallel yarns into working needles along the warp direction and simultaneously forms loops to create knitted fabrics. Its core function is to efficiently produce warp-knitted fabrics. The warp knitting machine's fabric tension adjustment device is a device used to dynamically adjust the tension of the fabric during the warp knitting process. Its core functions include maintaining the flatness of the fabric surface, preventing wrinkles or breaks, and adapting to the tension requirements of different materials and processes.

[0003] In the existing technology, the tension roller structure of the warp knitting machine fabric tension adjustment device is complex and the adjustment is troublesome. The traditional tension roller relies on a mechanical linkage structure, which requires manual and repeated adjustment of gear teeth or limit rod angles. The operation steps are cumbersome and time-consuming. The complex mechanical structure is prone to tension fluctuations due to component wear or fit errors, which can easily lead to problems such as machine stoppage, fabric shrinkage, etc., affecting the uniformity of the fabric and the quality of the finished product. It involves precision components such as gear teeth and linkage rods. During maintenance, multiple components need to be disassembled to clean the entangled material or replace worn parts, which increases downtime and labor costs. Therefore, it is necessary to improve the warp knitting machine fabric tension adjustment device to solve the above problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 6This utility model provides an embodiment of a warp knitting machine fabric tension adjustment device, including a support connecting seat 1, a first rotating shaft 801, and an adjustment assembly. A connecting mounting plate 2 is fixedly connected to the back of the support connecting seat 1. A guide shaft 3 for guiding the warp knitting machine fabric is rotatably connected to the inner side of the support connecting seat 1. The first rotating shaft 801 is rotatably connected inside the support connecting seat 1. A rotating handle 802 is fixedly connected to the right side of the first rotating shaft 801. A first gear 803 is fixedly connected to the first rotating shaft 801. A second rotating shaft 804 is rotatably connected inside the support connecting seat 1. A second gear 805 is fixedly connected to the second rotating shaft 804 and meshes with the first gear 803. A first guide disk 806 is fixedly connected to the left side of the second rotating shaft 804. A third rotating shaft 807 is rotatably connected inside the support connecting seat 1. A second guide disk 808 is fixedly connected to the right side of the third rotating shaft 807. A first limiting rod 809 and a second limiting rod 810 are slidably connected inside the first guide disk 806 and the second guide disk 808. When warp-knitted fabric is placed between the first limiting rod 809 and the second limiting rod 810, the rotating handle 802 is rotated to drive the first rotating shaft 801 to rotate. The rotation of the first rotating shaft 801 drives the first gear 803 and the second gear 805 to mesh and rotate. The rotation of the second gear 805 drives the second rotating shaft 804 to rotate. The second rotating shaft 804 drives... The first guide plate 806 rotates, and under the limitation of the first limiting rod 809 and the second limiting rod 810, it drives the second guide plate 808 to rotate. Through the cooperation of the second guide plate 808 and the first guide plate 806, the first limiting rod 809 and the second limiting rod 810 rotate, so that the tension of the warp-knitted fabric can be adjusted by adjusting the angle. The support connecting seat 1 has a groove at the corresponding position of the third rotating shaft 807. The third rotating shaft 807 rotates inside the groove. The groove at the corresponding position of the third rotating shaft 807 inside the support connecting seat 1 limits the rotation of the third rotating shaft 807 inside the groove. There are two connecting mounting plates 2, and the two connecting mounting plates 2 are symmetrically fixedly connected to the support connecting seat 1. On the back, two connecting mounting plates 2 are provided to make it more stable when the support connecting seat 1 is connected to the warp knitting machine. A support connecting block 811 is fixedly connected to the right side of the support connecting seat 1. A stop rod 812 is rotatably connected inside the support connecting block 811. The stop rod 812 is engaged inside the first gear 803. A return spring 813 is fixedly connected between the stop rod 812 and the support connecting block 811. When the tension of the warp-knitted fabric reaches the required tension, the return spring 813 pushes the stop rod 812 to engage inside the first gear 803, thereby fixing the rotation angle. A locking block is fixedly connected to the rotating handle 802. The first gear 803 is meshed with the locking block on the stop rod 812.This allows the stop lever 812 to engage with the inner side of the first gear 803, thus fixing the rotation of the first gear 803.

[0022] Please see Figure 5 - Figure 6 In this embodiment, the adjustment component includes a connecting limiting block 901, which is fixedly connected to the outside of the second guide disk 808. A drive motor 902 is fixedly connected to the connecting limiting block 901, and a rotating threaded rod 903 is fixedly connected to the output end of the drive motor 902. A first fixed limiting post 904 is fixedly connected inside the second guide disk 808. A sliding threaded block 905 is threadedly connected to the rotating threaded rod 903, and the sliding threaded block 905 is slidably connected to the first fixed limiting post 904. A first limiting rod 809 and a second limiting rod 810 are fixedly connected to the right side of the sliding threaded block 905. A fixed mounting post 906 is fixedly connected inside the first guide disk 806, and a sliding mounting post 906 is slidably connected to the outside of the fixed mounting post 906. The movable limiting block 907, the first limiting rod 809 and the second limiting rod 810 are fixedly connected to the left side of the first guide plate 806. The drive motor 902 drives the rotating threaded rod 903 to rotate inside the second guide plate 808. When the rotating threaded rod 903 is engaged with the sliding threaded block 905, the sliding threaded block 905 slides inside the second guide plate 808 under the limitation of the first fixed limiting post 904. The second guide plate 808 has a groove at the corresponding position of the sliding threaded block 905. The sliding threaded block 905 slides inside the groove. The groove at the corresponding position of the sliding threaded block 905 inside the second guide plate 808 limits the sliding threaded block 905 when it slides inside the groove.

[0023] During operation, the warp-knitted fabric is placed between the first limiting rod 809 and the second limiting rod 810. The drive motor 902 drives the rotating threaded rod 903 to rotate inside the second guide plate 808. With the rotating threaded rod 903 engaged with the sliding threaded block 905, the sliding threaded block 905 slides inside the second guide plate 808, limited by the first fixed limiting post 904. Rotating the rotating handle 802 causes the first rotating shaft 801 to rotate. The rotation of the first rotating shaft 801 drives the first gear 803 and the second gear 805 to mesh and rotate. The rotation of wheel 805 drives the second rotating shaft 804 to rotate, which in turn drives the first guide plate 806 to rotate. Under the limitation of the first limit rod 809 and the second limit rod 810, the second guide plate 808 is driven to rotate. Through the cooperation of the second guide plate 808 and the first guide plate 806, the first limit rod 809 and the second limit rod 810 are driven to rotate, so that the tension of the warp-knitted fabric can be adjusted according to the angle. When the tension of the warp-knitted fabric reaches the required tension, the set reset spring 813 pushes the stop rod 812 to engage inside the first gear 803, thereby fixing the rotation angle.

[0024] Through the above steps, by rotating the handle 802, the first gear 803 and the second gear 805 are engaged to drive the second rotating shaft 804 and the first guide plate 806 to rotate. The tension is adjusted by the first limit rod 809 and the second limit rod 810. This solves the problem that the complex structure and troublesome adjustment of the fabric tension adjustment device lead to complicated and time-consuming operation steps, which affect the uniformity of the fabric and the quality of the finished product, and increase downtime and labor costs.
