Technical Field
[0001] This utility model belongs to the technical field of tension control devices, and in particular relates to a yarn tension control device for warp knitting machines. Background Technology
[0002] During the operation of a warp knitting machine, precise control of yarn tension plays a decisive role in product quality. Traditional warp knitting machine yarn tension control devices have many shortcomings. On the one hand, their complex mechanical structure makes them prone to wear, resulting in large tension fluctuations that seriously affect the smoothness and uniformity of the fabric. On the other hand, their adjustment response speed is slow, and they cannot adjust to the appropriate tension in time when facing high-speed operation and frequent yarn variety changes, leading to frequent problems such as yarn breakage and defects. In addition, they lack intelligent monitoring and feedback mechanisms, making it difficult to adapt to the needs of modern refined and efficient production. Therefore, it is urgent to develop a new type of warp knitting machine yarn tension control device.
[0003] However, the existing warp knitting machine yarn tension control devices are not convenient to adjust the tension control range during use, making it difficult to meet the tension control range requirements of different yarn materials and complex knitting processes. Utility Model Content
[0004] The purpose of this utility model is to provide a yarn tension control device for warp knitting machines. By setting an adjustment mechanism, it solves the problem that existing yarn tension control devices for warp knitting machines are not convenient to adjust the tension control range during use, which makes it difficult to meet the tension control range requirements of different yarn materials and complex knitting processes.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a yarn tension control device for a warp knitting machine, including a base, on which an adjustment mechanism and an anti-rotation mechanism are provided;
[0007] The adjusting mechanism includes a threaded sleeve rotatably connected to the inner wall of the base. A threaded rod is threadedly connected to the inner wall of the threaded sleeve. A sliding platform is fixedly connected to the top of the threaded rod. Two supports are fixedly connected to the top of the base. The outer wall of the sliding platform is slidably connected to the two supports. Several sliding rods are slidably connected to the inner wall of the base. The sliding rods all penetrate the sliding platform, and the outer walls of the sliding rods are slidably connected to the sliding platform. The anti-rotation mechanism includes a support three fixedly connected to the bottom of the base. A rotating shaft three is rotatably connected to the inner wall of the support three.
[0008] Furthermore, two limiting blocks are fixedly connected to the bottom of several of the sliding rods, and sliders are slidably connected to the inner walls of both brackets.
[0009] Furthermore, each of the sliding rods has a spring sleeved on its outer wall, the top of each spring is fixedly connected to two sliders, the bottom of each spring is fixedly connected to a sliding platform, the inner walls of the two sliders are rotatably connected to a rotating shaft, and the outer wall of the rotating shaft is fixedly connected to a wheel.
[0010] Furthermore, the top of the base is fixedly connected to several brackets II, and the inner walls of the several brackets II are rotatably connected to two rotating shafts II.
[0011] Furthermore, a handle is fixedly connected to the outer wall of the rotating shaft three, and bevel gears are fixedly connected to both the outer wall of the rotating shaft three and the outer wall of the threaded sleeve, with the two bevel gears meshing with each other.
[0012] Furthermore, a ring is fixedly connected to the outer wall of the rotating shaft three, and a plurality of limiting grooves are opened on the outer wall of the ring, and a sliding groove is opened inside the bracket three.
[0013] Furthermore, a second slider is slidably connected to the inner wall of the slide groove, the second slider is adapted to several limiting grooves, a second spring is fixedly connected to the bottom of the inner wall of the slide groove, and the top of the second spring is fixedly connected to the second slider.
[0014] This utility model has the following beneficial effects:
[0015] 1. By setting an adjustment mechanism, when the threaded sleeve rotates, it drives the sliding platform to slide through the threaded rod, and applies pressure to several springs, causing them to undergo elastic deformation and generate elastic force. This changes the elastic coefficient of the springs and the force required to cause them to undergo elastic deformation. After adjusting the elastic coefficient of the springs according to the type of yarn, the yarn can be wound from the bottom of the rotating shaft on the right to the top of the rotating wheel, and then out from the bottom of the rotating shaft on the left. When the tension of the yarn increases, the slider will slide downward through the rotating wheel and the rotating shaft, thereby applying pressure to the springs, causing them to undergo elastic deformation and generate elastic force. Under the action of the elastic force, the tension will be balanced, allowing the tension control amplitude to be adjusted. This ensures that the device can cope with diverse yarn materials and complex weaving processes, meeting the requirements of different yarn materials and weaving processes for tension control amplitude, thus ensuring the stability of the production process.
[0016] 2. By setting an anti-rotation mechanism, before adjustment, press down on slider two to apply pressure to spring two, causing it to undergo elastic deformation and generate elastic force. When slider two slides out of the limit groove, the handle can be turned so that the threaded sleeve can be rotated through the rotating shaft three under the interaction of the two bevel gears. After adjustment, slider two can be released. At this time, under the action of the elastic force of spring two, slider two will be locked into the corresponding limit groove, which can prevent the device from rotating due to vibration when adjustment is not needed. This avoids the situation where rotation affects the operation of the device, thus ensuring the stable operation of the device.

[0028] The anti-rotation mechanism 3 includes a bracket 301 fixedly connected to the bottom of the base 1. A rotating shaft 302 is rotatably connected to the inner wall of the bracket 301. A handle 303 is fixedly connected to the outer wall of the rotating shaft 302. Bevel gears 304 are fixedly connected to both the outer wall of the rotating shaft 302 and the outer wall of the threaded sleeve 201, with the two bevel gears 304 meshing. A ring 305 is fixedly connected to the outer wall of the rotating shaft 302. Several limiting grooves 306 are provided on the outer wall of the ring 305.

When the tension of the yarn increases, the slider 207 will slide downward through the rotating wheel 210 and the rotating shaft 209, thereby applying pressure to springs 208, causing them to undergo elastic deformation and generate elastic force. Under the action of this elastic force, the tension will be balanced.
