Example two
[0033] Please refer to Figures 5-6 , and on the basis of example one, further get the placing mechanism 3.
[0034] The placing mechanism 3 comprises a third fixed frame 31, the third fixed frame 31 is fixedly connected to the top right side of the base 1, the bottom of the third fixed frame 31 is provided with a rotating rod 32 at equal intervals, the surface of the rotating rod 32 is fixedly connected with a second limiting ring 33 close to the bottom end, the surface of the rotating rod 32 is fixedly connected with a third limiting ring 34 above the second limiting ring 33, the surface of the rotating rod 32 is fixedly connected with a fixed disc 35 above the third limiting ring 34, the top end of the rotating rod 32 is fixedly connected with a screw 36, and the surface of the screw 36 is threadedly connected with a lifting disc 37.
[0035] The top of the third fixed frame 31 is provided with a hole matched with the rotating rod 32, and the surface of the rotating rod 32 penetrates and rotationally connects to the hole, the second limiting ring 33 and the third limiting ring 34 limit the rotating rod 32, so that the rotating rod 32 can stably rotate, and the fixed disc 35 and the lifting disc 37 fix the yarn cylinder.
[0036] In actual operation, when the device is in use, before the jacquard machine starts to work, the tension adjusting mechanism 2 is in the initial state. The servo motor 24 is not started, the lead screw 25 is static, the lifting plate 26 is kept in a fixed position under the limiting action of the limiting rod 27, and the second fixed plate 29 is connected with the lifting plate 26 through the lifting column 28 and is also in the initial position. At this time, the spring 215 keeps a certain compression or stretching state between the second fixed plate 29 and the second fixed frame 213, providing elastic force for subsequent adjustment, and the damping rod 216 connects the two, which can inhibit unnecessary vibration. The first rotating roller 217 and the second rotating roller 218 are installed in the inner wall of the first fixed frame 21, used to guide the pile yarn into and out of the tension adjusting area. When it is necessary to adjust the tension of the pile yarn, the control system sends a command to the servo motor 24, and the servo motor 24 starts to rotate, driving the lead screw 25 to rotate. Since the lifting plate 26 is threadedly connected with the lead screw 25 and can only move up and down by being limited by the limiting rod 27, the rotation of the lead screw 25 makes the lifting plate 26 slide up and down along the limiting rod 27. The lifting plate 26 drives the second fixed plate 29 to move synchronously through the lifting column 28, and the second fixed plate 29 changes the distance between the second fixed plate 29 and the second fixed frame 213 during the movement, thereby compressing or stretching the spring 215. The change of the spring force of the spring 215 is transmitted to the adjusting roller 214 through the guide rod 211, so that the pressure of the adjusting roller 214 on the pile yarn changes, thereby realizing the adjustment of the tension of the pile yarn. When the tension of the pile yarn fluctuates, the spring 215 and the damping rod 216 work together, the spring 215 absorbs and releases energy to buffer the tension change, and the damping rod 216 inhibits the rebounding vibration of the spring 215, ensuring that the tension of the pile yarn is stable within the set range. The pile yarn enters the tension adjusting mechanism 2 from the first rotating roller 217, the tension is adjusted after passing through the adjusting roller 214, and then is output from the second rotating roller 218, entering the subsequent weaving link;
[0037] In the placing mechanism 3, the third fixed frame 31 is fixed on the right side of the top of the base 1, providing support for the whole placing structure. When installing the yarn cylinder, the yarn cylinder is sleeved on the rotating rod 32, so that the yarn cylinder is located between the fixed disc 35 and the lifting disc 37. The second limiting ring 33 and the third limiting ring 34 on the surface of the rotating rod 32 limit the position of the yarn cylinder on the rotating rod 32, ensuring the accuracy of the installation position of the yarn cylinder. Then, the lifting disc 37 is rotated and moved downward on the bolt 36 until the lifting disc 37 is in close contact with the top of the yarn cylinder, so that the yarn cylinder is stably fixed on the rotating rod 32. When the jacquard machine works and the yarn is needed, the yarn is unwound from the yarn cylinder. Since the rotating rod 32 is rotationally connected with the third fixed frame 31, under the action of the tension generated by the unwinding of the yarn, the rotating rod 32 can stably rotate around its own axis. The second limiting ring 33 and the third limiting ring 34 prevent the rotating rod 32 from axially moving during rotation, ensuring the stability of the yarn unwinding process. The fixed disc 35 and the lifting disc 37 continuously clamp the yarn cylinder, so that the yarn cylinder does not shake or fall off during rotation and unwinding, ensuring that the yarn can be continuously and stably supplied to the tension adjusting mechanism 2, providing a reliable source of yarn for the weaving work of the jacquard machine.

Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
