Description

Technical Field

[0001] This utility model relates to the field of yarn production technology, specifically to a tension adjustment device for yarn production. Background Technology

[0002] After the yarn passes through the dyeing and printing equipment and undergoes the dyeing process, it is transferred to the take-up device for winding. During this process, excessive tension can easily cause yarn breakage, while insufficient tension can easily cause the yarn to become disordered. Therefore, a tension adjustment device is required.

[0003] However, a utility model patent with authorization announcement number CN215625893U discloses a yarn tension adjustment device for recycled yarn textiles, including a base. From back to front, the top of the base is sequentially equipped with a first mounting frame, a cleaning component, a second mounting frame, and a third mounting frame. A rotating roller is movably installed between the two sets of first mounting frames. Multiple yarn-dividing discs are fixedly sleeved on the outer wall of the rotating roller. A first tensioning roller is movably installed between the two sets of second mounting frames. A top plate is fixedly connected to the top of the two sets of third mounting frames. Grooves are provided on opposite sides of the two sets of third mounting frames, and a lead screw is movably installed within the grooves. A lead screw lifting seat is movably sleeved on the outer wall of the lead screw. A second tensioning roller is movably installed between the two sets of lead screw lifting seats. A transmission component is provided on the top right side of the top plate. This utility model can separate the incoming yarn, making it less prone to tangling and misalignment. It can also clean the yarn, improving its quality.

[0004] Based on existing solutions and practical production applications, current tension adjustment devices for yarn production still have some problems. For example, while two sets of cylinders drive the brushes downward to clean the yarn, cleaning the lower end of the yarn is inconvenient, the structure is relatively complex, and the cleaned impurities remain inside the cleaning box, making removal difficult and reducing work efficiency. Furthermore, the second tension roller is adjusted via two sets of lead screws, a drive motor, pulleys, and belts, but the adjustment structure is also complex. Therefore, we propose a tension adjustment device for yarn production to solve the problems mentioned above. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-7 This utility model provides a technical solution: a tension adjustment device for yarn production, including a workbench 1, a first mounting plate 2, a guide roller 3, a first connecting frame 4, a second connecting frame 5, an adjusting rod 6, a cleaning brush 7, a connecting port 8, a guide rod 9, a first mounting groove 10, a second mounting groove 11, a connector 12, a limiting strip 13, a connecting ear 14, a second mounting plate 15, a first tensioning roller 16, a connecting frame 17, a cylinder 18, a mounting frame 19, a second tensioning roller 20, an adjusting block 21, and a long groove 22.

[0035] Example 1: Existing methods use two sets of cylinders 18 to lower the brush bristles and clean the yarn. However, cleaning the lower end of the yarn is inconvenient and the structure is relatively complex. Therefore, this example uses the following technical solution, as shown in Figures 1 and 2. Figure 3 and Figure 7The cleaning structure includes a first connecting frame 4, a second connecting frame 5, an adjusting rod 6, a cleaning brush 7, a connecting port 8, and a guide rod 9. The outer surface of the adjusting rod 6 has a bidirectional threaded structure. The connecting frame 17 is symmetrically threaded on the adjusting rod 6. The second connecting frame 5 and the left and right walls of the first connecting frame 4 are equally spaced with connecting ports 8. The cleaning brush 7 slides inside the first connecting frame 4 through the adjusting rod 6 and the guide rod 9, so that the yarn is distributed on the guide roller 3 and the yarn passes through and connects to the equally spaced connecting ports 8. Rotating the adjusting rod 6 makes it rotate inside the second connecting frame 5 and the second mounting groove 11. The guide rod 9 drives the symmetrically arranged cleaning brushes 7 to move closer to each other until the inner walls of the symmetrically arranged cleaning brushes 7 abut against the upper and lower ends of the yarn. When the yarn moves, the symmetrically arranged cleaning brushes 7 clean it, which makes it easy to clean yarns of different thicknesses.

[0036] Example 2: Existing methods adjust the lifting and lowering of the second tension roller using two sets of lead screws, a drive motor, pulleys, belts, and other components. However, the adjustment structure is relatively complex. Therefore, this example uses the following technical solution: Figure 1 , Figure 6 As shown in Figure 7, since the front and rear walls of the mounting frame 19 are both inlaid with adjusting blocks 21, and the outer ends of the adjusting blocks 21 are slidably connected to the inside of the long groove 22, the second tension roller 20 is in a lifting structure on the upper side of the worktable 1 through the adjusting blocks 21 and the long groove 22. Therefore, when it is necessary to adjust the tension, the cylinder 18 is activated to drive the mounting frame 19 to move up and down, and the symmetrically arranged adjusting blocks 21 slide up and down in the corresponding long groove 22. The second tension roller 20 is stably lifted and lowered through the cylinder 18, the mounting frame 19, the adjusting blocks 21 and the long groove 22, so that the height of the second tension roller 20 can be easily adjusted. The adjustment structure is simple.

[0037] Example 3: Existing methods leave impurities inside the cleaning box, making removal inconvenient and reducing work efficiency. Therefore, this example addresses this issue by implementing the following technical solution: Figure 2 , Figure 3 , Figure 4 and Figure 5Since the limiting structure includes a first mounting groove 10, a second mounting groove 11, a connector 12, a limiting strip 13, and a connecting ear 14, the lower end of the adjusting rod 6 is nested inside the second mounting groove 11, the lower end of the guide rod 9 is threaded inside the first mounting groove 10, the lower end of the second connecting frame 5 is symmetrically rotatably connected to the connector 12, and the left end of the limiting strip 13 is nested inside the hollow structure of the connecting ear 14, when cleaning the cleaning brush 7, the symmetrically arranged connector 12 is rotated to disengage the symmetrically arranged limiting strip 13 from the hollow structure of the corresponding connecting ear 14. The guide rod 9 is rotated to disengage its lower end from the inside of the first mounting groove 10, and the second connecting frame 5 is pulled upwards to remove the adjusting rod 6 and the cleaning brush 7 from the inside of the first connecting frame 4. The impurities inside the first connecting frame 4 and the impurities on the cleaning brush 7 are removed and collected, thus facilitating disassembly and collection of the cleaned impurities. All the electrical components mentioned above are existing technologies and will not be described in detail here.
