Description

Technical Field

[0001] The invention relates to the technical field of cloth detection, and in particular to a device for detecting the anti-ultraviolet performance of textile cloth. Background Art

[0002] Anti-UV textile fabrics are special textile materials that have the function of blocking or reflecting ultraviolet rays, designed to protect the skin from the harm of ultraviolet radiation. This type of fabric achieves anti-UV performance through a variety of methods, including the use of fiber materials with high ultraviolet absorption or reflection capabilities (such as polyester or nylon) and the addition of chemical components such as ultraviolet absorbers and reflectors during the fiber manufacturing process. In addition, the structural design of the fabric, such as increasing the tightness of the fabric or enhancing the ultraviolet blocking effect through special weaving processes, can also significantly improve the anti-UV performance. Some anti-UV fabrics also use post-processing technology, such as coating with anti-UV coating or special dyeing and finishing treatment, to further enhance the protection ability. This type of material is widely used in outdoor clothing, awnings, tents and other fields. It can not only effectively reduce the damage of ultraviolet rays to human skin, but also prevent the textile itself from aging due to ultraviolet radiation. It has good practicality and durability. In order to improve the protection effect, the anti-UV performance of the textile fabric needs to be tested before it leaves the factory. During the test, the textile fabric is generally spread flat and moved, and then the anti-UV light test is performed on the textile fabric in a straight shape.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0023] In the field of textile fabrics, anti-ultraviolet textile fabrics, as a special textile material with the function of blocking or reflecting ultraviolet rays, are widely used in outdoor clothing, awnings, tents and other fields to protect human skin from the harm of ultraviolet radiation. The realization of anti-ultraviolet performance relies on a variety of technical means, including the use of fiber materials with high ultraviolet absorption or reflection ability (such as polyester fiber, nylon, etc.), and the addition of chemical components such as ultraviolet absorbers and reflectors during the fiber manufacturing process. In addition, the structural design of the fabric is also an important factor in achieving the anti-ultraviolet effect, such as increasing the tightness of the textile or using a special weaving process to enhance the ultraviolet blocking ability. Some anti-ultraviolet fabrics will also undergo post-processing technology, such as coating with anti-ultraviolet coating or special dyeing and finishing treatment, to further enhance the protective effect. The combination of these technologies can not only effectively reduce the damage of ultraviolet rays to human skin, but also prevent the aging of textiles under long-term ultraviolet radiation, ensuring the durability and practicality of the materials during use. However, with the development and application of these technologies, the quality control of textile fabrics is particularly critical, especially during factory inspection.

[0024] In order to ensure that the anti-ultraviolet performance of textile fabrics meets the predetermined standards, it is usually necessary to conduct ultraviolet performance testing. During the testing process, textile fabrics are generally laid in a straight state, exposed to ultraviolet rays, and their transmittance, ultraviolet blocking rate and other indicators are tested. This detection method in a straight state is relatively simple. The ultraviolet protection effect of the fabric is evaluated by testing its transmittance, which meets most industry standards. However, with the development of technology and changes in demand, problems gradually emerge. In long-term practice, the inventors found that although textile fabrics can achieve the expected protection effect when they are tested for anti-ultraviolet in a straight state, in actual applications, especially after the fabrics are processed into clothing or other protective products, the fabrics often undergo deformation processes such as bending and folding. Because the ultraviolet transmittance of the fabric may change in a bent state, especially some textile fabrics that show good ultraviolet protection effects in a straight state may significantly decrease in a bent state. This problem has not been effectively solved in the existing detection methods, resulting in certain quality risks. For example, although the ultraviolet transmittance of some anti-ultraviolet fabrics in a straight state meets the standard, the transmittance after bending may be unqualified, thereby affecting the anti-ultraviolet performance of the final product. This problem is particularly prominent in products such as protective clothing and tents that need to be bent and folded. After bending, the UV protection performance of the fabric is insufficient, which may cause workers wearing these protective clothing to be exposed to UV radiation, posing potential health risks.

[0025] At present, most of the existing technologies only perform anti-ultraviolet tests on fabrics in a straight state, and lack a comprehensive assessment of the anti-ultraviolet performance of fabrics in a bent state. For example, Chinese patent application number CN202411443296.4 discloses a device for detecting the anti-ultraviolet performance of textile fabrics. The device can only detect fabrics in a straight state, but cannot effectively detect the ultraviolet transmittance of fabrics in a bent state. The defects of this technology have led to insufficient evaluation of the anti-ultraviolet performance of fabrics in actual use, and thus cannot fully and accurately reflect the actual protective capabilities of the fabrics. Especially when producing protective clothing, tents, and other products that require fabrics to be used in a bent state, traditional detection methods fail to effectively predict whether the fabric can continue to provide sufficient ultraviolet protection after bending.

[0026] Therefore, the main disadvantage of the prior art is that it only considers the UV protection performance of the fabric in a straight state, while ignoring the performance of the fabric in a bent state, resulting in insufficient assessment of the UV radiation risks that may occur in actual use. In order to solve this problem, it is necessary to develop a new detection method or device that can accurately detect the UV resistance of the fabric when it is in a bent state, so as to ensure that even if the fabric is deformed, it can still meet the corresponding UV protection standards. The proposal of this technical problem can not only improve the quality control level of anti-UV textile fabrics, but also ensure the safety and reliability of protective clothing, awnings and other products in actual applications, thereby providing the textile industry with more accurate detection technology and enhancing the market competitiveness of products.

[0027] Based on this, the present application provides a device for detecting the anti-ultraviolet performance of textile fabrics.

[0028] Please refer to Figure 1 to Figure 11 The device comprises an unwinding mechanism 1, a first traversing mechanism 2, a second traversing mechanism 3, an adjusting passing mechanism 4, a linear ultraviolet sensor detection mechanism 5 and an arc ultraviolet sensor detection mechanism 6; wherein, the unwinding mechanism 1 is horizontally spaced apart in two groups, and is used for releasing and rewinding the textile fabric to be detected respectively; the first traversing mechanism 2 and the second traversing mechanism 3 are horizontally spaced apart between the two groups of unwinding mechanisms 1, and are used for allowing the textile fabric to be detected to pass horizontally in sequence.

[0029] At the same time, the adjusting passing mechanism 4 is installed at intervals between the first crossing mechanism 2 and the second crossing mechanism 3. The adjusting passing mechanism 4 is used for the textile fabric to be detected to pass through, and the adjusting passing mechanism 4 has at least a switchable first state and a second state. When the adjusting passing mechanism 4 is in the first state, the textile fabric to be detected that passes through the first crossing mechanism 2, the adjusting passing mechanism 4 and the second crossing mechanism 3 in sequence is in a horizontally extended state; when the adjusting passing mechanism 4 is in the second state, the textile fabric to be detected that passes through the first crossing mechanism 2, the adjusting passing mechanism 4 and the second crossing mechanism 3 in sequence forms a downward arc-shaped concave fabric segment and an upward arc-shaped convex fabric segment.

[0030] Furthermore, a group of linear ultraviolet sensor detection mechanisms 5 are respectively provided on the first traversing mechanism 2 and the second traversing mechanism 3, and the linear ultraviolet sensor detection mechanisms 5 are used to detect the ultraviolet transmittance of the textile fabric in a horizontal straight line state; the arc ultraviolet sensor detection mechanism 6 is provided on the adjusting passing mechanism 4, and the arc ultraviolet sensor detection mechanism 6 is used to respectively detect the ultraviolet transmittance of the concave part of the fabric segment that is concave in a downward arc shape and the convex part of the fabric segment that is convex in an upward arc shape.

[0031] On this basis, by setting the unwinding mechanism 1 and the first and second traversing mechanisms 3, the textile fabric to be tested can be horizontally transported and controlled in the device, thereby ensuring stable testing of the fabric in different states. The horizontal spacing setting of the unwinding mechanism 1 keeps the fabric flat and controllable during the unwinding and winding process, avoiding wrinkles or deformation of the fabric, and ensuring the accuracy of the subsequent testing process.

[0032] Secondly, the design of the adjustment through mechanism 4 has an important technical effect. The mechanism can be switched to the first state and the second state, so that the fabric can be detected in the two states respectively. In the first state, the textile fabric to be detected is in a horizontal extension state. In this state, the ultraviolet transmittance of the fabric is measured by the linear ultraviolet sensor detection mechanism 5. Through this measurement, the ultraviolet protection effect of the fabric in a straight state can be obtained, and accurate detection data can be provided to manufacturers to evaluate the anti-ultraviolet performance of the fabric. At the same time, when the adjustment through mechanism 4 is switched to the second state, the shape of the fabric changes, forming a fabric section with a downward arc depression and an upward arc protrusion, thereby simulating the bending, folding and other states that may occur in the actual use of the fabric, especially in the actual application of protective clothing and sunshade materials, the fabric often needs to be used in a bent state. At this time, the arc ultraviolet sensor detection mechanism 6 comes into play, respectively detecting the ultraviolet transmittance of the downward arc depression part and the upward arc protrusion part. The technical effect of this design is that it can truly reflect the anti-ultraviolet performance of the fabric in a bent state, ensuring that the final product can provide sufficient ultraviolet protection in actual use, and avoiding potential ultraviolet damage due to incomplete detection.

[0033] Furthermore, by providing a linear ultraviolet sensor detection mechanism 5 and an arc ultraviolet sensor detection mechanism 6, the device can accurately detect the ultraviolet transmittance of fabrics in different forms. The linear ultraviolet sensor detection mechanism 5 can effectively detect the ultraviolet blocking performance of the fabric in a straight state, and provide standardized measurement results for the quality control of the fabric. The arc ultraviolet sensor detection mechanism 6 detects the light transmittance of the fabric in a bent state, making up for the deficiency of the prior art that the performance of the fabric after bending cannot be measured. This can comprehensively evaluate the ultraviolet protection ability of the fabric in various application scenarios, thereby improving the quality reliability of the product.

[0034] The technical effect of the present invention is also reflected in the optimization of the production process. Traditional anti-ultraviolet performance testing is limited to the flat state of the fabric, and it is impossible to predict the changes in ultraviolet transmittance that may be caused by changes in the fabric state such as bending and folding during actual use. However, by performing ultraviolet transmittance testing on the fabric in the flat state and the bent state respectively, the present device can provide a more comprehensive and accurate performance evaluation and provide more powerful data support for the quality control of the fabric. In this way, not only the accuracy of the test results is improved, but also the efficiency of the test process is improved, saving the manufacturer time and cost in the fabric testing link.

[0035] In addition, the device of the present invention is simple in design and easy to operate, and can complete the detection of the ultraviolet transmittance of the fabric without excessive processing of the fabric. The structure of the device can be adjusted according to actual needs to meet the detection requirements of textile fabrics of different types, thicknesses, and textures. This flexibility not only enhances the applicability of the equipment, but also improves the versatility of the device, and can meet the detection requirements of a variety of textile fabric products.

[0036] In summary, the textile fabric anti-ultraviolet performance detection device of the present invention realizes comprehensive detection of the ultraviolet transmittance of fabrics under different conditions through innovative structural design, which makes up for the shortcomings of the existing technology, provides more accurate and comprehensive performance evaluation, and ensures the safety and reliability of anti-ultraviolet textile fabrics in actual use. In addition, the device has high operational convenience and applicability, can provide manufacturers with efficient and accurate detection tools, improve the quality control level of products, ensure that the final product can provide effective ultraviolet protection in actual applications, and reduce the quality defects of textile fabrics after leaving the factory.

[0037] In some embodiments, Figure 1~Figure 3 As shown, the first cross-crossing mechanism 2 includes a first bracket 21 and a first cross-crossing tube 22, the first cross-crossing tube 22 is horizontally arranged above the first bracket 21, and the first cross-crossing tube 22 is used for the textile fabric released from the unwinding mechanism 1 to pass horizontally; the second cross-crossing mechanism 3 includes a second bracket 31 and a second cross-crossing tube 32, the second cross-crossing tube 32 is horizontally arranged above the second bracket 31, and the second cross-crossing tube 32 is used for the textile fabric released from the unwinding mechanism 1 to pass horizontally.

[0038] Exemplarily, the first cross-tube 22 and the second cross-tube 32 are horizontally spaced apart and face each other.

[0039] Such an arrangement ensures that the textile fabric to be tested can be smoothly unwound from the unwinding mechanism 1 and transmitted through the intervals of the first transverse tube 22 and the second transverse tube 32 without deviation or entanglement. Through this arrangement, the fabric can remain straight during the detection process, avoiding wrinkles or uneven stretching of the fabric during transportation, thereby ensuring the stability of the fabric shape during the detection process, thereby improving the accuracy of ultraviolet transmittance detection. At the same time, this configuration enables the device to efficiently handle textile fabrics of different specifications and sizes, providing better adaptability and flexibility. In addition, the facing arrangement of the first transverse tube 22 and the second transverse tube 32 ensures uniform stretching of the fabric in the horizontal direction, effectively avoiding deviation or deformation of the fabric during the crossing process, thereby further ensuring accurate measurement of the fabric's anti-ultraviolet performance.

[0040] In some embodiments, in combination Figure 1~Figure 3 The linear ultraviolet sensor detection mechanism 5 includes a first ultraviolet light source emitter 51 and a first ultraviolet light source detection sensor 52. The first ultraviolet light source emitter 51 is arranged at the upper ends of the first transverse tube 22 and the second transverse tube 32, and the emitting end of the first ultraviolet light source emitter 51 is vertically downward toward the first transverse tube 22 and the second transverse tube 32; exemplarily, the first ultraviolet light source detection sensor 52 is arranged at the lower ends of the first transverse tube 22 and the second transverse tube 32, and the receiving end of the first ultraviolet light source detection sensor 52 is vertically opposite to the emitting end of the first ultraviolet light source emitter 51, so that the ultraviolet light emitted by the first ultraviolet light source emitter 51 is incident on the receiving end of the first ultraviolet light source detection sensor 52 after passing through the textile fabric; exemplarily, the area of ​​the receiving end of the first ultraviolet light source detection sensor 52 is larger than the area of ​​the emitting end of the first ultraviolet light source detection sensor 52.

[0041] Exemplarily, an opening is provided on the upper tube wall of the first cross tube 22 and the second cross tube 32 for the emitting end of the first ultraviolet light source emitter 51 to extend into, and the outside of the first ultraviolet light source emitter 51 is sealed to the edge of the opening to minimize the leakage of ultraviolet rays emitted by the first ultraviolet light source emitter 51.

[0042] This arrangement allows the ultraviolet rays to be evenly irradiated to the textile fabric to be tested in a vertical direction. This structure ensures that the ultraviolet rays can penetrate the surface of the textile in a straight line when passing through the fabric, and avoids the deviation of the ultraviolet light source at other angles, thereby improving the accuracy of the detection process.

[0043] At the same time, the first ultraviolet light source detection sensor 52 is arranged at the lower end of the first cross tube 22 and the second cross tube 32, and its receiving end is vertically opposite to the transmitting end of the ultraviolet light source transmitter, ensuring that the ultraviolet light emitted by the ultraviolet light source transmitter can directly penetrate the textile fabric and enter the receiving end of the light source detection sensor. This alignment setting greatly reduces the deviation of the optical path and the measurement error, making the detection of ultraviolet light passing through the fabric more accurate. In particular, the area of ​​the receiving end of the first ultraviolet light source detection sensor 52 is larger than the area of ​​its transmitting end. This design ensures that the sensor can effectively capture ultraviolet light passing through the textile fabric, which not only improves the sensitivity of the received signal, but also enhances the stability of ultraviolet transmittance detection. The larger receiving end area can effectively avoid inaccurate measurements caused by ultraviolet scattering or light source emission angle errors, ensuring the reliability and consistency of the measurement.

[0044] In general, the linear ultraviolet sensor detection mechanism 5 optimizes the ultraviolet emission and receiving system to make the detection process more accurate and efficient. The vertical downward emission of the transmitter and the precise alignment of the sensor ensure the consistency of the optical path between the ultraviolet rays and the textile fabric, and avoid the detection deviation caused by the angle error. At the same time, the design of increasing the receiving end area improves the sensitivity and fault tolerance of the detection sensor, so that the detection system can work stably under different textile fabrics, different thicknesses and different textures, and further improves the adaptability and practicality of the entire detection device. Therefore, the linear ultraviolet sensor detection mechanism 5 effectively improves the detection accuracy, stability and reliability of the device, and provides more scientific and accurate data support for the evaluation of the anti-ultraviolet performance of textile fabrics.

[0045] In some embodiments, in combination Figure 3~Figure 7 The adjusting passing mechanism 4 includes a frame 41, an adjusting passing tube 42, a driving assembly 43 and a pushing assembly 44. The frame 41 is arranged between the first bracket 21 and the second bracket 31, the driving assembly 43 is arranged on the frame 41, and the adjusting passing tube 42 is arranged on the driving assembly 43 and is used for textile fabrics to pass through.

[0046] Exemplarily, the driving assembly 43 is used to drive the adjusting tube 42 to rotate, and a pushing assembly 44 is respectively provided at both ends of the adjusting tube 42. The pushing assembly 44 has a switchable horizontal supporting state and an arc-shaped supporting state. When the pushing assembly 44 switches to the arc-shaped supporting state, the pushing assembly 44 pushes part of the textile fabric located on the outside of the two ends of the adjusting tube 42 to an arc shape, so that part of the textile fabric located on the outside of the two ends of the adjusting tube 42 forms a downward arc-shaped concave fabric segment and an upward arc-shaped convex fabric segment.

[0047] Exemplarily, when the adjusting passing mechanism 4 is in the first state, the adjusting passing tube 42 is in a horizontal state under the action of the driving component 43 and is horizontally opposite to the first cross-tube 22 and the second cross-tube 32, and the pushing component 44 automatically switches to a horizontal supporting state; when the adjusting passing mechanism 4 is in the second state, the adjusting passing tube 42 is in an inclined state under the action of the driving component 43 and is vertically displaced with the first cross-tube 22 and the second cross-tube 32, and the pushing component 44 automatically switches to an arc-shaped supporting state.

[0048] On this basis, the adjustment tube 42 can flexibly adjust its state under the drive of the driving component 43, thereby changing the shape of the textile fabric passing through the adjustment tube 42. Specifically, when the adjustment through mechanism 4 is in the first state, the adjustment tube 42 is in a horizontal state, horizontally facing the first transverse tube 22 and the second transverse tube 32, and the push component 44 automatically switches to a horizontal support state. In this state, the textile fabric to be tested is in a straight shape, which is suitable for measuring the linear ultraviolet transmittance. This design ensures that during the routine detection process, the fabric can smoothly pass through the sensor area, thereby ensuring that the measurement result of the ultraviolet transmittance is accurate.

[0049] When the adjusting through mechanism 4 is switched to the second state, the adjusting through tube 42 is in an inclined state under the action of the driving component 43, and is vertically displaced with the first transverse tube 22 and the second transverse tube 32, and the pushing component 44 automatically switches to an arc-shaped supporting state. In this state, the pushing component 44 pushes part of the textile fabric located outside the two ends of the adjusting through tube 42 to an arc shape, forming a fabric segment that is concave in an arc downward and a fabric segment that is convex in an arc upward. This design simulates the bending state that may occur in the fabric in actual use, especially in the manufacturing process of protective clothing, the fabric may bend or wrinkle due to wearing. Therefore, this design can comprehensively evaluate the anti-ultraviolet performance of the fabric in different states, and ensure its ultraviolet protection effect in actual use.

[0050] Through this switching function, the adjustment through mechanism 4 can accurately detect the ultraviolet transmittance of the fabric in different states, avoiding the limitation of only detecting the fabric in a straight state in the traditional technology. The application of this technology further improves the accuracy, comprehensiveness and practical applicability of the anti-ultraviolet performance detection, ensures the ultraviolet protection effect of the finished products such as protective clothing in actual use, thereby effectively improving the quality inspection level of textile fabrics and providing reliable technical support for product quality assurance in related fields.

[0051] In some embodiments, in combination Figure 5~Figure 8, the driving assembly 43 includes a servo motor 431 and a connecting rod 432, wherein the connecting rod 432 is respectively provided on both sides of the middle part of the adjusting tube 42, and the two connecting rods 432 are axially opposite, wherein one connecting rod 432 is coaxially connected to the output shaft of the servo motor 431, and the connecting rod 432 is perpendicular to the length direction of the adjusting tube 42. Exemplarily, the adjusting tube 42 is in the shape of a rectangle, and the connecting rod 432 is parallel to the center line of the adjusting tube 42. In this way, the servo motor 431 can accurately control the rotation of the adjusting tube 42, so as to freely switch between the horizontal state and the inclined state, thereby realizing the precise adjustment of the textile fabric shape on the side. Through this coaxial connection and vertical arrangement structure, the connecting rod 432 can effectively transmit the driving force of the servo motor 431, ensure the stable movement of the adjusting tube 42, and avoid the deviation or uneven rotation caused by unstable connection.

[0052] At the same time, the application of the servo motor 431 ensures the high-precision adjustment capability of the drive assembly 43, and can adjust the angle and position of the adjustment tube 42 in real time according to the detection needs, thereby realizing accurate testing of the fabric in different forms. In addition, the design of the connecting rod 432 being perpendicular to the length direction of the adjustment tube 42 makes the motion transmission more stable and efficient, effectively preventing the torque deviation or motion resistance that may occur during the connection process, and further improving the stability and reliability of the system. Through these optimized designs, the present invention can achieve precise control of the change in fabric shape, thereby improving the accuracy of ultraviolet transmittance detection and the adaptability to practical applications.

[0053] In some embodiments, in combination Figure 5~Figure 11 The push-pull assembly 44 includes a bent tube body 441, a skin 442, a threading ring 443, a torsion spring 444, a pulling rope 445 and a winding wheel 446. Placement grooves are provided on both sides of the end opening of the adjusting tube 42. The placement groove close to the first cross tube 22 is located above one of the end openings of the adjusting tube 42, and the placement groove close to the second cross tube 32 is located below the other end opening of the adjusting tube 42.

[0054] Exemplary, combined Figure 5~Figure 7 , one part of the bent tube body 441 is located in the placement groove, and the other part extends from the placement groove to the distal end of the end opening of the adjustment tube 42, and the bent tube body 441 is composed of a plurality of axially hinged tubes 4411; Exemplary, combined Figure 7~Figure 9 Three groups of bent tube bodies 441 are arranged in parallel, the first group is connected to the placement groove, the second and third groups of bent tube bodies 441 are located outside the placement groove, and the skin 442 is sleeved on the outer periphery of the three groups of bent tube bodies 441 to form a fitting surface that can be squeezed and fitted with textile fabrics.

[0055] Exemplary, combined Figure 9~Figure 11 The torsion spring 444 is arranged at the hinge of two adjacent trustees 4411. When the torsion spring 444 is in a natural state, it drives the two adjacent trustees 4411 to be parallel in the axial direction, so that the bent tube body 441 is in a straight state in the natural state. Further, the hinge of the two adjacent trustees 4411 is located in the axial middle of the trustee 4411, and there is a rotation gap between the two adjacent trustees 4411. The rotation gap is arranged on both sides of the radial direction of the hinge, and along the radial direction of the trustee 4411, the opening width of the rotation gap gradually increases from the side close to the intersection to the side away from the hinge, so that the two adjacent trustees 4411 can achieve relative bending and rotation.

[0056] Exemplary, combined Figure 10~Figure 11 The threading ring 443 is arranged on the inner wall of the tube 4411. When the bent tube body 441 is in a straight state, the threading rings 443 in the multiple tubes 4411 are axially facing each other. In the three groups of bent tube bodies 441 close to the first transverse tube 22, the threading ring 443 is arranged on the upper inner wall of the tube 4411 in the third group of bent tube bodies 441. In the three groups of bent tube bodies 441 close to the second transverse tube 32, the threading ring 443 is arranged on the lower inner wall of the tube 4411 in the second group of bent tube bodies 441. In this way, the pulling ropes 445 located at both ends of the adjusting tube 42 can drive the bent tube bodies 441 without interfering with each other during the bending process.

[0057] For example, refer to Figure 8 , Fig. 9 The second and third groups of the trolley bodies 441 are connected to the second and third groups of the trolley bodies 442 and 443 respectively.

[0058] On this basis, the push-pull assembly 44 achieves effective control of the shape of the textile fabric through the design of the bent tube body 441. The bent tube body 441 is composed of a plurality of axially hinged tubes 4411, and three groups are arranged in parallel, of which the first group is connected to the placement slot, and the second and third groups are located outside the placement slot. The skin 442 covers the periphery of the three groups of bent tube bodies 441 to form a fitting surface that can be squeezed and fitted with the textile fabric. This design ensures that the fabric can be evenly and accurately in contact with the bent tube body 441 during the bending process, and form a bending shape that meets the actual use conditions. The biggest advantage of this structure is that it can adapt to the dynamic changes of the textile fabric. Whether it is bent into a downward arc-shaped depression or an upward arc-shaped convexity, it can accurately control the shape of the fabric and provide reliable data for subsequent ultraviolet transmittance detection.

[0059] Secondly, the setting of the torsion spring 444 enables the bent tube 441 to maintain a straight state in a natural state, and during the adjustment process, the state of the bent tube 441 changes through the drive of the servo motor 431. The torsion spring 444 plays an important role at the hinge of the adjacent tube 4411. It not only ensures that the bent tube 441 automatically returns to a straight state in a non-working state, but also provides a smooth and resistance-free transition during operation, avoiding the jamming phenomenon caused by friction or excessive force, thereby effectively improving the stability and service life of the device.

[0060] The design of the threading ring 443 increases the precision of the system. Each tube 4411 is provided with a plurality of threading rings 443, and when the bent tube 441 is in a straight state, the axial direction of the threading ring 443 is aligned, ensuring that the pulling rope 445 can move along a predetermined route, avoiding slippage or uneven force between the fabric and the equipment. The reasonable arrangement of the threading ring 443 enables the pulling rope 445 to effectively drive the shape change of the fabric and accurately control the bending state of the fabric.

[0061] The design of the winding wheel 446 is also a highlight of the present invention. Two groups of winding wheels 446 are coaxially arranged on a connecting rod 432, corresponding to the second and third groups of bending tube bodies 441 respectively. The synchronous rotation of the winding wheel 446 can realize the gradual winding of one end of the pulling rope 445, and the shape change of the bending tube body 441 is driven by the pulling rope 445, thereby controlling the bending state of the textile fabric. Under the action of the servo motor 431, the two groups of winding wheels 446 on the connecting rod 432 work together to drive the bending tube body 441 to gradually change from a straight line state to a downward bend or an upward bend, ensuring that the shape of the textile fabric during the detection process meets the actual use conditions. Through this precise control, the bending state of the fabric is closely related to the detection result of the ultraviolet transmittance, thereby improving the reliability of the detection.

[0062] In general, by integrating a series of innovative designs such as the bending tube 441, the torsion spring 444, the pulling rope 445, and the winding wheel 446 in the push-pull assembly 44, the precise control of the textile fabric in different states is ensured, so that the detection device can adjust the shape of the fabric according to actual needs, which not only ensures the accuracy of the detection, but also avoids errors caused by the unstable state of the fabric. This technology breaks through the limitation that the existing detection device can only detect fabrics in a straight state, so that the detection results are more in line with actual use conditions, and has a wider application prospect, especially suitable for outdoor protective clothing, sunshade fabrics, etc., which need to consider the anti-ultraviolet performance detection of the bending shape. At the same time, this design has a simple structure and is easy to operate. It can improve production efficiency and service life while ensuring high precision, and has an important role in supplementing and improving the existing technology.

[0063] It is worth noting that the principle that the pulling rope 445 drives the bent tube body 441 to rotate in a predetermined direction after passing through multiple threading rings 443 is as follows: when the winding wheel 446 pulls the pulling rope 445 on one side, the pulling rope 445 will apply a pulling force to the fixed point connected to the trustee 4411, and this force will generate a torque on the trustee 4411. Due to the torsion of the torsion spring 444, this unbalanced torque will force the trustee 4411 to bend in the direction of the pulling force. At this time, the torsion spring 444 will provide a certain support force for the trustee 4411 to prevent the trustee 4411 from excessive displacement or instability during the bending process. In summary, the core principle of bending the bent tube body 441 by rotating and pulling the pulling rope 445 on one side of the winding wheel 446 lies in the cumulative effect of unilateral moment imbalance and bending angle. By reasonably designing the layout of the pulling rope 445 and the structure of the trustee 4411, it is possible to make the bent tube body 441 bend according to a preset route.

[0064] In some embodiments, reference Figure 3 , Figure 5 and Figure 6 The arc ultraviolet sensor detection mechanism 6 includes a left sensor detection component 61 and a right sensor detection component 62. The left sensor detection component 61 and the right sensor detection component 62 are both arranged between the frame 41 and the adjustment tube 42. The left sensor detection component 61 is used to detect the ultraviolet transmittance of the textile fabric at the downward arc-shaped depression, and the right sensor detection component 62 is used to detect the ultraviolet transmittance of the textile fabric at the upward arc-shaped protrusion.

[0065] Exemplarily, the left-side sensor detection assembly 61 includes a left-side ultraviolet light source emitter 611 and a left-side ultraviolet light source detection sensor 612. A left-side L-shaped bracket 421 is provided at the upper end of the opening of the adjusting tube 42 near the first cross tube 22. The left-side ultraviolet light source emitter 611 is arranged on the left-side L-shaped bracket 421. The left-side ultraviolet light source detection sensor 612 is arranged on the frame 41 and is located below the left-side ultraviolet light source emitter 611. When the servo motor 431 drives the adjusting tube 42 to rotate to a tilted state, the transmitting end of the left-side ultraviolet light source emitter 611 rotates to a receiving end vertically facing the left-side ultraviolet light source emitter 611, and the end face shape of the receiving end of the left-side ultraviolet light source emitter 611 is an arc-shaped depression that matches the downward arc-shaped depression of the textile fabric.

[0066] Exemplarily, the right sensor detection assembly 62 includes a right ultraviolet light source emitter 621, a right ultraviolet light source detection sensor 622 and a cylinder 623. A right L-shaped bracket 422 is provided at the upper end of the opening of the adjusting tube 42 close to the second transverse tube 32. The right ultraviolet light source emitter 621 is provided on the right L-shaped bracket 422. The cylinder 623 is provided on the frame 41 and the piston rod of the cylinder 623 extends vertically upward. The right ultraviolet light source detection sensor 622 is provided on the piston rod of the cylinder 623 and is located below the right ultraviolet light source emitter 621. When the servo motor 431 drives the adjusting tube 42 to rotate to a tilted state, the emitting end of the right ultraviolet light source emitter 621 rotates to be vertically opposite to the receiving end of the right ultraviolet light source emitter 621, and the cylinder 623 drives the receiving end of the right ultraviolet light source emitter 621 to move upward and close to the emitting end of the right ultraviolet light source emitter 621, and the end face shape of the receiving end of the right ultraviolet light source emitter 621 is an arc-shaped protrusion that matches the upward arc-shaped protrusion of the textile fabric.

[0067] In this way, the left sensor detection component 61 and the right sensor detection component 62 are respectively configured to correspond to the UV transmittance detection requirements of the fabric in different bending shapes. The left sensor detection component 61 is used to detect the UV transmittance of the textile fabric when it is in a downward arc-shaped depression, while the right sensor detection component 62 is used to detect the UV transmittance of the fabric when it is in an upward arc-shaped convexity. This design enables the detection device to flexibly adjust the detection position and direction according to the different bending shapes of the fabric, thereby realizing accurate measurement of the UV transmittance of the fabric in different shapes, avoiding measurement errors caused by changes in the shape of the fabric.

[0068] Secondly, in the specific implementation of the left sensor detection component 61, the left ultraviolet light source emitter 611 is arranged on the left L-shaped bracket 421, and the emitted ultraviolet light can accurately irradiate the downward arc-shaped concave part of the cloth. The left ultraviolet light source detection sensor 612 is located below the ultraviolet light source emitter. When the adjustment tube 42 is rotated to the inclined state, the emitting end of the ultraviolet light source emitter is vertically facing the receiving end of the ultraviolet light source detection sensor. At this time, the end face shape of the receiving end is designed to be an arc-shaped concave that matches the downward bending shape of the cloth, thereby ensuring the accurate irradiation and detection of ultraviolet light, and improving the detection accuracy of ultraviolet light transmittance.

[0069] In terms of the right sensor detection component 62, the right ultraviolet light source emitter 621 is fixed by the right L-shaped bracket 422, and the cylinder 623 adjusts the lifting and lowering of the piston rod to achieve precise docking between the ultraviolet light source emitter and the detection sensor. When the servo motor 431 drives the adjustment tube 42 to rotate to the tilted state, the transmitting end of the right ultraviolet light source emitter 621 is vertically facing the receiving end of the ultraviolet light source detection sensor, and the cylinder 623 drives the receiving end of the detection sensor to move upward and close to the ultraviolet light transmitting end. At this time, the end face shape of the receiving end is designed to be an arc-shaped protrusion that matches the upward bending shape of the textile fabric, thereby ensuring that the ultraviolet light emitter and the receiving end can perform effective ultraviolet transmittance detection when the fabric is in an upward arc-shaped protrusion state.

[0070] In summary, the present invention solves the problem of insufficient accuracy in detecting ultraviolet transmittance of textile fabrics in a bent and deformed state in the prior art through the innovative design of the sensor detection assembly. The precise layout of the left and right sensor detection assemblies 62, as well as the adaptive design of the ultraviolet light source and the receiving sensor, ensure that the ultraviolet transmittance under different bending forms can be accurately and comprehensively measured. This not only improves the performance and reliability of the anti-ultraviolet performance detection device, but also broadens its scope of application in practical applications, especially in the detection of outdoor, sunshade and sunscreen textile products, and has significant technical advantages.

[0071] In some embodiments, reference Figure 6 , a limit block 411 is provided on the frame 41. When the servo motor 431 drives the adjusting tube 42 to rotate to the tilted state, the limit block 411 abuts against the outer tube wall of the adjusting tube 42 to limit the continued movement of the adjusting tube 42. Exemplarily, a limit block 411 is staggered and distributed on the upper and lower sides of the adjusting tube 42 on the frame 41. When the adjusting tube 42 rotates to the tilted state, the upper and lower tube walls of the adjusting tube 42 respectively cooperate with a limit block 411 to effectively limit the rotation of the adjusting tube 42.

[0072] In some embodiments, reference Figure 1~Figure 3The unwinding mechanism 1 includes an unwinding frame 11, an unwinding wheel 12 and a rotating motor 13. The unwinding wheel 12 is rotatably arranged on the unwinding frame 11, and the rotating motor 13 is arranged on the unwinding frame 11, and the output shaft of the rotating motor 13 is coaxially connected with the unwinding wheel 12 to drive the unwinding wheel 12 to rotate. The unwinding wheel 12 can be rotated by starting the rotating motor 13, so that one unwinding wheel 12 can release the textile fabric and the other unwinding wheel 12 can synchronously wind the textile fabric. It is worth noting that in the process of adjusting the through mechanism 4 to switch from the first state to the second state, the rotating motor 13 is turned off in advance, so that the two unwinding wheels 12 are in an idling state that is not affected by the rotating motor 13. At this time, when the textile fabric changes from a straight state to a partially bent state, a certain pulling force will be generated on the part of the textile fabric wound on the unwinding wheel 12. At this time, the part of the textile fabric on the unwinding wheel 12 in the idling state can be pulled out to adapt to the shape change of the textile fabric.

[0073] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
