[0010] When the yarn is loosened, the tension wheel can be driven downward to press the yarn tightly, thereby realizing adaptive tensioning of the yarn.

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.
[0025] The utility model discloses a tension adjustment structure for a yarn drawing machine, which is mainly used in traditional yarn drawing machines where tension adjustment mostly adopts mechanical or pneumatic structures. The adjustment accuracy is easily affected by factors such as ambient temperature and mechanical wear, resulting in large fluctuations in yarn tension. In addition, some adjustment devices need to stop or slow down when adjusting the tension, affecting the continuity and efficiency of the production line.
[0026] Reference Figure 1 、 Figure 2 and Figure 4 A tension adjustment structure for a yarn warp drawing machine includes an installation box 1, a connecting frame 2 is provided on one side outer wall of the installation box 1, a mounting frame 3 is provided on the top outer wall of the connecting frame 2, and further includes:
[0027] The first adjustment mechanism is located on the inner walls of both sides of the connecting frame 2. The first adjustment mechanism includes a fixing frame 14. The bottom outer wall of the fixing frame 14 is provided with a plurality of guide rods 15 and a plurality of return springs 16. One end of the return spring 16 is fixedly connected to a connecting plate 17. The return spring 16 is wound around the circumferential outer wall of the guide rod 15. The bottom outer wall of the connecting plate 17 is provided with a limiting cylinder 18. The circumferential outer wall of the limiting cylinder 18 is provided with a tensioning wheel 19. The circumferential outer wall of the tensioning wheel 19 is provided with a groove.
[0028] Transmission mechanism: located on one outer wall of the fixed frame 14;
[0029] The second adjustment mechanism is located on the inner walls of both sides of the installation box 1.
[0030] Among them, a limiting opening is opened on the top outer wall of the connecting plate 17, and the interior of the limiting cylinder 18 is a hollow structure. The limiting opening is communicated with the interior of the limiting cylinder 18. When the yarn becomes taut, the connecting plate 17 and the limiting cylinder 18 provide space for vertical movement of the guide rod 15, ensuring stability during the movement.
[0031] During actual use, the plurality of guide rods 15 and the plurality of return springs 16 are distributed at equal distances.
[0032] The bottom of the installation box 1 and the connecting frame 2 are each provided with two supporting columns, thereby providing support for the entire device.
[0033] Specifically, when in use, first install all four support columns on the yarn drawing machine, and then pass one end of multiple yarns through the second adjusting mechanism, the transmission mechanism and the groove of the tensioning wheel 19 in turn, and automatically adjust the tension of the yarn through the provided tensioning wheel 19 and the return spring 16. When the yarn is relaxed, the tensioning wheel 19 can be driven to extend downward under the action of the return spring 16 to press the yarn, thereby realizing adaptive tensioning of the yarn. When the yarn is taut, the tensioning wheel 19 will be subjected to the reaction force from the yarn and slide upward along the guide rod 15 until it reaches a new equilibrium position. In this process, the contact force between the tensioning wheel 19 and the yarn will change, but due to the presence of the return spring 16, this change will be limited to a reasonable range to keep the yarn tension relatively stable. As the tensioning wheel 1 9 rises, the connecting plate 17 will also rise accordingly, thereby compressing the reset spring 16. Due to the elasticity of the spring, it will store a certain amount of potential energy and is ready to release energy when the yarn is relaxed, so that the tensioning wheel 19 moves downward to re-tighten the yarn. The groove design on the tensioning wheel 19 allows the yarn to bypass stably, which not only reduces the friction loss between the yarn and the tensioning wheel 19, but also improves the accuracy of tension adjustment. When the tensioning wheel 19 is pressed down by the action of the reset spring 16, the groove will fit closely to the yarn, thereby increasing the pressing force on the yarn and realizing automatic adjustment of the tension. This device can respond quickly according to changes in yarn tension and realize precise adjustment of tension. It allows tension adjustment without stopping or slowing down, ensuring the continuity and efficiency of the production line, making the adjustment process faster and more flexible, and improving production efficiency.
[0034] Reference Figure 1 In a preferred embodiment, the transmission mechanism includes two transmission rollers 13, which are located on the inner walls of opposite sides of the mounting frame 3. A fixed frame 4 is provided on the outer wall of one side of the mounting frame 3, and a motor 5 is provided on the outer wall of one side of the fixed frame 4. The output shaft of the motor 5 is fixedly connected to one of the transmission rollers 13, and a transmission belt 6 is sleeved on the circumferential outer walls of the two transmission rollers 13.
[0035] The two driving rollers 13 are symmetrically distributed with the straight line where the fixing frame 14 is located as the symmetry axis.
[0036] Specifically, when in use, the motor 5 is started, and the output shaft of the motor 5 drives one of the transmission rollers 13 to rotate, and under the action of the transmission belt 6, the other transmission roller 13 is driven to rotate, thereby realizing the conveying of the yarn.
[0037] Reference Figure 2 and Figure 3In a preferred embodiment, the second adjustment mechanism includes an upper pressing roller 11 and a lower pressing roller 12, and connecting blocks 8 are provided at both ends of the upper pressing roller 11 and the lower pressing roller 12. Connecting grooves are provided on the inner walls of both sides of the installation box 1, and the bottom inner wall of the connecting groove is connected to a threaded rod 10 through a bearing. The two adjacent connecting blocks 8 are connected to the circumferential outer wall of the threaded rod 10 through threads. Two mounting ports 9 are provided on the top outer wall and the bottom outer wall of the installation box 1, and the connecting blocks 8 correspond to the mounting ports 9 one by one.
[0038] Among them, the outer wall of the threaded rod 10 is provided with two threads in opposite directions. This arrangement makes it convenient for the two connecting blocks 8 to move closer to or away from each other when one threaded rod 10 rotates, thereby improving the practicality of the equipment according to the production requirements of yarns of different specifications.
[0039] Specifically, by rotating the threaded rod 10, the two connecting blocks 8 can be moved closer to or farther away from each other on the threaded rod 10, thereby adjusting the distance between the upper pressing roller 11 and the lower pressing roller 12, thereby enabling the equipment to adapt to the production requirements of yarns of different specifications and materials, thereby improving the flexibility and versatility of the equipment. The provided installation port 9 facilitates providing moving space for the connecting block 8.
[0040] Working principle: When in use, first install all four support columns on the yarn drawing machine, and then pass one end of multiple yarns through the second adjustment mechanism, the transmission mechanism and the groove of the tensioning wheel 19 in turn. The tension of the yarn is automatically adjusted by the provided tensioning wheel 19 and the reset spring 16. When the yarn is relaxed, the tensioning wheel 19 can be driven downward by the action of the reset spring 16 to press the yarn to achieve adaptive tensioning of the yarn. When the yarn is taut, the tensioning wheel 19 will be subjected to the reaction force from the yarn and slide upward along the guide rod 15 until it reaches a A new equilibrium position. During this process, the contact force between the tensioning wheel 19 and the yarn will change, but due to the presence of the reset spring 16, this change will be limited to a reasonable range to keep the yarn tension relatively stable. As the tensioning wheel 19 rises, the connecting plate 17 will also rise accordingly, thereby compressing the reset spring 16. Due to the elasticity of the spring, it will store a certain amount of potential energy and is ready to release energy when the yarn is relaxed, so that the tensioning wheel 19 moves downward to re-tighten the yarn, so that it can respond quickly according to the change of yarn tension and realize precise adjustment of the tension.
