Description

Technical Field

[0001] This disclosure relates to a tension detection and control component, and more particularly to a fabric tension detection and control component. Background Technology

[0002] Conventional techniques for judging the quality of rayon lack objective conditions for assessment. Errors in judging dyeing conditions often arise in different environments or among different inspectors (even those with varying physiological conditions), hindering the improvement of accuracy and efficiency. Furthermore, dyeing conditions are related to the tension of the fabric (e.g., garters). Differences in garter tension cause variations in color depth on the fabric surface, affecting the inspector's perception. However, devices for tension sensing and adjustment are lacking, making it difficult to stabilize product quality, enhance product functionality, and conduct continuous quality monitoring during production.

[0003] Currently, garter belts are woven by adjusting the yarn tension using the yarn feeding device of a sock knitting machine. However, there are variations in yarn tension during the weaving process. These variations can affect the dyeing rate of the garter belts or the color interpretation due to the weaving density. Therefore, it is impossible to adjust the yarn tension of the yarn feeding device or the weaving speed in real time according to the variations in garter belt tension, resulting in unstable tension in the woven garter belts. Summary of the Invention

[0004] According to some embodiments disclosed herein, a fabric tension detection and control assembly includes a detection plate, an elastic element, a first magnetic element, a shaping block, a lifting device, a pressure sensing device, and a second magnetic element. A fabric is fitted onto the detection plate. One end of the elastic element is located on the detection plate. The first magnetic element is located at the other end of the elastic element away from the detection plate and is situated within the fabric. The shaping block covers the first magnetic element and is situated within the fabric, causing the fabric to be stretched open by the shaping block. The lifting device is located below the shaping block. The pressure sensing device is located on the lifting device. The second magnetic element is located on the pressure sensing device. The lifting device is configured to rise or fall to bring the second magnetic element closer to or away from the first magnetic element. The pressure sensing device is configured to sense changes in the repulsive force between the first and second magnetic elements.

[0005] In some embodiments, the shaping block has a first surface facing away from the first magnetic element, and the first surface of the shaping block is in direct contact with the fabric.

[0006] In some embodiments, the first surface of the aforementioned molding block is a convex arc surface.

[0007] In some embodiments, the shaping block has a second surface facing the first magnetic element, and the second surface of the shaping block is in direct contact with the first magnetic element.

[0008] In some embodiments, the shaping block is located between the first magnetic element and the fabric.

[0009] In some embodiments, the pressure sensing device is located between the lifting device and the second magnetic element.

[0010] In some embodiments, the elastic element, the shaping block, and the first magnetic element are located between the detection plate and the fabric.

[0011] In some embodiments, the first magnetic element and the second magnetic element overlap in the vertical direction.

[0012] In some embodiments, the width of the first magnetic element is greater than the width of the second magnetic element.

[0013] In some embodiments, the elastic element is a spring, and the pressure sensing device is an electronic scale.

[0014] In the above-disclosed embodiment, since the two ends of the elastic member are respectively connected to the detection plate and the first magnetic member, and the shaping block covers the first magnetic member, when the fabric is fitted onto the detection plate, the elastic member, the first magnetic member, and the shaping block can be located within the fabric, and the fabric can be stretched open by the shaping block. Furthermore, since the lifting device located below the shaping block can raise and lower the second magnetic member, the distance between the first and second magnetic members can be changed, thereby adjusting the repulsive force between them. Additionally, the pressure sensing device located between the lifting device and the second magnetic member can sense changes in the repulsive force between the first and second magnetic members, and this measurement result, combined with the elastic coefficient (K value) of the elastic member and the weight of the first and second magnetic members, can be used to obtain the fabric tension.

[0036] Figure 1 A top view is shown of a fabric 210 fitted onto a detection plate 110 according to an embodiment of this disclosure. Figure 2 The diagram illustrates a cross-sectional view of a fabric tension detection and control assembly 100 according to an embodiment of this disclosure, wherein the fabric 210 and the detection plate 110 are along... Figure 1 The cross-sectional location of line segment 2-2. See also... Figure 1 and Figure 2The fabric tension detection and control assembly 100 includes a detection plate 110, an elastic element 120, a first magnetic element 130, a shaping block 140, a lifting device 150, a pressure sensing device 160, and a second magnetic element 170. Fabric 210 is fitted onto the detection plate 110. One end of the elastic element 120 (e.g., the upper end of the elastic element 120) is located on the detection plate 110. The first magnetic element 130 is located at the other end of the elastic element 120 away from the detection plate 110 (e.g., the lower end of the elastic element 120). That is, both ends of the elastic element 120 abut against the detection plate 110 and the first magnetic element 130, respectively. The shaping block 140 covers the first magnetic element 130 and the elastic element 120. Figure 2 In the diagram, the molding block 140 is represented by the area surrounded by a thick black line. For clarity, the first magnetic element 130 and the elastic element 120 are represented by solid lines. In reality, the first magnetic element 130 and part of the elastic element 120 are housed within the molding block 140.

[0037] When the fabric 210 is fitted onto the detection plate 110, the elastic element 120, the first magnetic element 130, and the shaping block 140 are all located within the fabric 210, and the fabric 210 is supported by the shaping block 140. Region A is the tension control range of the fabric 210. The lifting device 150 is located below the shaping block 140. The pressure sensing device 160 is located on the lifting device 150. The second magnetic element 170 is located on the pressure sensing device 160. In use, the lifting device 150 can rise to bring the second magnetic element 170 closer to the first magnetic element 130, or the lifting device 150 can fall to move the second magnetic element 170 away from the first magnetic element 130. Furthermore, the pressure sensing device 160 can sense changes in the repulsive force between the first magnetic element 130 and the second magnetic element 170, thereby achieving non-contact transmission and feedback of stress. In this way, the first magnetic element 130 and the second magnetic element 170 can use the principle of like poles repulsion to provide feedback to the pressure sensing device 160 on the tension changes of the fabric 210.

[0038] In some embodiments, fabric 210 may be a dyed garter belt, trouser leg, or similar item. The material of fabric 210 may be rayon, such as polyester. The detection plate 110 may be a dyeing discrimination template with rounded ends to facilitate the application and natural stretching of fabric 210. Furthermore, the elastic element 120 may be a spring with a spring constant (K-value). The first magnetic element 130 and the second magnetic element 170 may be magnets, such as permanent magnets. The pressure sensing device 160 may be an electronic scale with piezoelectric material. The lifting device 150 may be a jack with elements for manual or automatic height adjustment (e.g., a rotating rod or motor).

[0039] Specifically, since the two ends of the elastic member 120 are respectively connected to the detection plate 110 and the first magnetic member 130, and the shaping block 140 covers the first magnetic member 130, when the fabric 210 is fitted onto the detection plate 110, the elastic member 120, the first magnetic member 130, and the shaping block 140 can be located within the fabric 210, and the fabric 210 can be stretched open by the shaping block 140. Furthermore, since the lifting device 150 located below the shaping block 140 can raise and lower the second magnetic member 170, the distance between the first magnetic member 130 and the second magnetic member 170 can be changed, thereby adjusting the repulsive force between the first magnetic member 130 and the second magnetic member 170. In addition, the pressure sensing device 160 located between the lifting device 150 and the second magnetic member 170 can sense the change in repulsive force between the first magnetic member 130 and the second magnetic member 170. This measurement result can be combined with the elastic coefficient (K value) of the elastic member 120 and the weight of the first magnetic member 130 and the second magnetic member 170 to obtain the tension of the fabric 210.

[0040] In this embodiment, the shaping block 140 has a first surface 142 facing away from the first magnetic member 130 and a second surface 144 facing the first magnetic member 130. The first surface 142 of the shaping block 140 directly contacts the fabric 210. For example, the first surface 142 of the shaping block 140 is a convex arc surface, while the second surface 144 is a concave surface. The second surface 144 of the shaping block 140 can directly contact the first magnetic member 130. Furthermore, the shaping block 140 is located between the first magnetic member 130 and the fabric 210. The pressure sensing device 160 is located between the lifting device 150 and the second magnetic member 170. The elastic member 120, the first magnetic member 130, and the shaping block 140 are located between the detection plate 110 and the fabric 210. The first magnetic member 130 and the second magnetic member 170 overlap in the vertical direction, and the width of the first magnetic member 130 is greater than the width of the second magnetic member 170.

[0041] It should be understood that the component connections, materials, and functions already described will not be repeated, but will be stated in advance. In the following description, the state of the fabric tension detection and control component 100 and the fabric 210 will be explained when the lifting device 150 rises.

[0042] Figure 3 Draw Figure 2A cross-sectional view of the lifting device 150 during its ascent. When the lifting device 150 rises in direction D, the second magnetic member 170 approaches the first magnetic member 130, increasing the repulsive force between them. As a result, the elastic member 120 is compressed due to the upward movement of the first magnetic member 130, and the pressure sensing device 160 also senses the increased downward pressure from the second magnetic member 170. Furthermore, because the fabric 210 is elastic, the shaping block 140 moves upward along with the first magnetic member 130, eventually stopping upon contact with the detection plate 110. Figure 3 Fabric 210 in region A compared to Figure 2 It exhibits a relatively relaxed state, meaning it has less tension.

[0043] Conversely, when the lifting device 150 descends in the opposite direction to direction D, it can return to... Figure 2 In this state, the second magnetic member 170 moves away from the first magnetic member 130, reducing the repulsive force between them. As a result, the elastic member 120 elongates due to the downward movement of the first magnetic member 130, and the pressure sensing device 160 also senses the decrease in downward pressure from the second magnetic member 170. Furthermore, because the first magnetic member 130 and the shaping block 140 themselves have weight, the shaping block 140 allows the fabric 210 to bulge downwards. Figure 2 Fabric 210 in region A compared to Figure 3 It exhibits a relatively taut state, meaning it is under considerable tension.

[0044] It should be understood that the lifting device 150, in addition to being able to stop at the aforementioned... Figure 2 and Figure 3 The tension of the fabric 210 can be detected and controlled at various heights, including the height at which it can be stopped, and at other heights, according to user needs, fabric product requirements, or textile equipment requirements. The fabric tension detection and control component 100 has functions such as tension measurement, tension setting, real-time tension adjustment, constant tension control, and tension data feedback.

[0045] In summary, the fabric tension detection and control component facilitates process improvements in yarn grading, preventing color differences in woven fabrics (using garters as an example) and dyed fabrics from being affected by uneven garter tension. As an automated detection device, the component enhances accuracy and efficiency, stabilizing product quality, increasing functionality, and enabling continuous quality monitoring during production. Furthermore, it allows for weaving tension adjustment, further enhancing product functionality. The component detects garter tension in real-time by detecting the pressure feedback from the shaping block restrained by the garter. Combined with a lifting device, it alters the relative position of the shaping block and the garter, applying tension to the fabric surface and adjusting the tension value to achieve controllable tension during garter transport. This controllable tension allows for more objective and accurate post-dyeing garter readings, enabling dyeing and grading under consistent tension conditions, thus leading to more objective and accurate quality grading. Furthermore, the fabric tension detection and control component utilizes the properties of magnetic lines of force, allowing non-metallic materials (such as garters) to pass through the middle region of the magnetic lines of force, and extending the tension from within the garter's surface. This component can be used not only for warp tension control in traditional weaving machines but also for the production or inspection of hollow webbing (such as garters), making it widely applicable. The fabric tension detection and control component can detect changes in garter tension during the weaving process and feed the data (such as measurements from a pressure sensor) back to the knitting machine to adjust the yarn tension of the yarn feeding device or the weaving speed in real time, ensuring stable tension in the woven garters.

Those skilled in the art should understand that they can readily use this disclosure as the basis for designing or modifying other processes and structures to achieve the same purposes and / or advantages as the embodiments described herein.
