Description

Technical Field

[0001] The invention belongs to a textile fabric anti-ultraviolet radiation detection device, and in particular relates to a textile fabric ultraviolet radiation shielding effect testing device and a testing method thereof. Background Art

[0002] At present, testing the UV blocking effect in textile fabric testing is of great significance, mainly reflected in the following aspects: First, from the perspective of human protection, ultraviolet rays are harmful to human skin. Long-term exposure may cause skin cancer, sunburn, skin aging and other problems. Testing the UV blocking effect of fabrics can ensure that people can effectively block UV rays when wearing related textiles, such as sun-protective clothing, and provide a reliable protective barrier for the human body. Secondly, for some special application scenarios, such as outdoor work, sports equipment and other fields, the good UV blocking performance of fabrics can improve the comfort and safety of users during outdoor activities, reduce the adverse effects of ultraviolet rays on the body, and ensure that people can better perform various outdoor operations and sports;

[0003] Chinese patent publication number "CN212722610U" discloses a device for testing the ultraviolet shielding effect of textile fabrics. The device includes a support mechanism for supporting the device, a test mechanism for testing the ultraviolet shielding effect of the textile fabric, and a control mechanism for controlling the operation of the device. The test mechanism is mounted above the support mechanism, and the control mechanism is fixed above the test mechanism. By providing a test mechanism and adopting a closed environment for testing, the present invention can prevent ultraviolet radiation leakage from posing a health hazard to workers. By providing a control mechanism, a breathable net facilitates heat dissipation in the control box, thereby extending the service life of the controller.

[0004] In the process of textile fabric testing, although the device for testing the UV blocking effect can play a certain detection efficiency, it still exposes many defects and shortcomings in actual application. On the one hand, the device can only perform auxiliary testing on a single piece of fabric to be tested. When facing the needs of large-scale fabric testing, especially for long rolls of textile fabrics, its limitations are particularly obvious. In this case, the device cannot directly test the roll of fabric. The finished textile fabric must be cut into small pieces before being placed in the equipment for testing. On the other hand, the device cannot be integrated into the textile fabric production line to realize real-time detection during the production process. Under the conventional testing process, once it is found that the UV shielding effect of the fabric is unqualified, it is very likely that there are quality problems with the fabrics produced on the entire production line recently. Since the problem cannot be discovered and corrected in time during the production process, this not only leads to a large amount of material waste, but also seriously affects production efficiency and product quality. In addition, during the testing period, the overall elasticity of different fabrics to be tested is different. If they cannot be stably stretched, it is very easy to cause wrinkles on the fabric. At this time, it is impossible to conduct a true and accurate test. In summary, in order to meet the needs of the modern textile industry for efficient and accurate testing, there is an urgent need to improve the design of existing testing equipment.

[0017] A method for testing the ultraviolet light shielding effect of textile fabrics comprises the following steps:

[0018] Step 1: Fabric placement: The fabric to be tested is introduced through the slot on one side of the box, wrapped around the outer surface of the tensioning guide roller and the guide roller, and then led out from the slot on the other side of the box to form a coherent testing path;

[0019] Step 1: Tension adjustment: Start the third motor. The power generated by the motor is transmitted to the second screw. The rotation of the second screw drives the longitudinal movable block to slide up and down, thereby driving the horizontal rail to move synchronously. During this process, the oblique movable block rotates in conjunction with the horizontal movable block. The oblique movable block slides outward along the oblique rail, pushing the elastic component. The elastic component drives the frame and the tensioning guide roller to move downward, increasing the distance between the tensioning guide roller and the guide roller, pulling the fabric to a taut state. At the same time, the buffer spring and the slide cooperate to provide buffering.

[0020] Step 2: Prepare for online testing. Utilize the characteristics of the rotational connection between the tensioning guide roller and the guide roller to integrate the device into the textile fabric production line.

[0021] Step 3: Ultraviolet irradiation: start the ultraviolet emitter and irradiate the fabric to be tested in a targeted manner;

[0022] Step 4: Initial angle adjustment: Start the first motor. The motor output shaft drives the gear to rotate. The gear drives the gear ring meshing with it, which drives the slip ring to rotate in the annular groove in the circular groove, causing the inner rail frame to rotate, and then drives the sphere in the top frame to rotate, achieving the initial angle adjustment of the UV emitter.

[0023] Step 5: Fine angle adjustment: Start the second motor, which drives the first screw in the inner rail frame to rotate, causing the sliding block to slide horizontally. The sliding block drives the sleeve and the slide bar to swing, causing the top sphere to rotate longitudinally while rotating itself, achieving horizontal and vertical angle adjustment of the UV emitter lamp, and comprehensively testing the UV protection ability of the fabric;

[0024] Step 6: Online testing is performed. The finished fabric enters the trough at the input end of the box and is tested in real time with the help of the UV generator and UV intensity detector with adjusted angles. After the test is completed, the fabric is discharged from the trough at the discharge end and wound up by the winding device.

[0025] In summary, the present invention mainly has the following beneficial effects:

[0026] First, this device greatly improves the practicality and accuracy of the textile fabric detection device through the innovative setting of the positioning mechanism. The fabric to be tested can easily pass through the troughs on both sides of the box body and wrap around the tensioning guide roller and the guide roller to form a coherent detection path. After starting the third motor, the power is transmitted through the second screw to drive the longitudinal movable block and the cross rail to move up and down. The oblique movable block and the transverse movable block are rotated and linked through the mechanical structure to push the elastic component and the frame to move the tensioning guide roller downward, increase the distance with the guide roller, and pull the fabric to be taut. At the same time, the buffer spring and the slide cooperate for buffering, and the adjustment mechanism and linkage component accurately adjust the distance to adapt to different fabrics. Moreover, because the tensioning guide roller and the guide roller are rotatably connected, the device can be integrated into the production line to realize real-time online detection and avoid the production of defective products.

[0027] Second, the device is equipped with an ultraviolet generating mechanism, which comprehensively enhances the comprehensiveness and flexibility of the ultraviolet blocking effect test. During the test, the ultraviolet emitter is started to irradiate the fabric to be tested in a direction, and the ultraviolet intensity detector on the top monitors the penetrating light in real time, quickly and accurately detecting the ultraviolet intensity. To simulate different scenarios, the device is carefully designed with an angle adjustment function. The first motor is started to drive the gear drive gear ring, so that the slip ring and the inner rail frame rotate to achieve the initial angle adjustment of the ultraviolet emitter. Then the second motor is started to drive the screw to make the sliding block slide horizontally, driving the sleeve and the slide rod to swing, so that the sphere rotates in all directions, thereby flexibly adjusting the irradiation angle of the ultraviolet emitter to comprehensively test the ultraviolet protection ability of the fabric.

[0028] Third, the device is designed to be seamlessly integrated into the textile fabric production line through the rotational connection of the tensioning guide roller and the guide roller. During the production process, the finished textile fabric enters the trough at the input end of the box, is irradiated by the ultraviolet generating mechanism and detected by the ultraviolet intensity detector, and then is discharged from the discharge end trough and reeled in by the reeling device. This design directly replaces the tensioning mechanism of the reeling device, does not require pre-cutting of the fabric, and can be tested online in real time. Once the ultraviolet shielding effect of the fabric is found to be abnormal, production can be adjusted in time, effectively avoiding the occurrence of a large number of defective products, significantly improving production efficiency, reducing production costs, and meeting the needs of modern textile production.

[0029] Fourth, through the innovative design of the test device for the UV blocking effect of textile fabrics, it can fully meet diverse testing needs. The positioning mechanism ensures stable tension of different elastic fabrics, improves detection accuracy, and is integrated into the design of the production line to achieve real-time detection and reduce the defective rate. The UV generating mechanism can not only detect the UV intensity in real time, but also flexibly change the irradiation angle of the UV emission lamp through a complex and sophisticated dual-motor drive adjustment mechanism, simulate a variety of actual scenarios, and comprehensively and accurately test the UV protection ability of fabrics under UV irradiation at different angles, providing strong support for textile fabric quality control and promoting technological progress in the textile industry.

[0045] A method for testing the ultraviolet light shielding effect of textile fabrics comprises the following steps:

[0046] Step 1: Fabric placement: The fabric to be tested 8 is introduced through the groove body 4 on one side of the box body 3, so that it wraps around the outer surface of the tensioning guide roller 64 and the guide roller 65, and then guided out from the groove body 4 on the other side of the box body 3 to form a coherent detection path;

[0047] Step 1: Tension adjustment: Start the third motor 612. The power generated by the motor is transmitted to the second screw rod 613. The second screw rod 613 rotates to drive the longitudinal movable block 614 to slide up and down, thereby pushing the cross rail 622 to move synchronously. During this process, the oblique movable block 623 and the transverse movable block 625 rotate in conjunction. The oblique movable block 623 slides outward along the oblique rail 621, pushing the elastic component 63. The elastic component 63 drives the frame 632 and the tensioning guide roller 64 to move downward, increasing the distance between the tensioning guide roller 64 and the guide roller 65, pulling the fabric to a taut state. At the same time, the buffer spring 633 and the slide 634 cooperate to provide buffering.

[0048] Step 2: Online testing preparation, utilizing the characteristics of the rotational connection between the tensioning guide roller 64 and the guide roller 65 to integrate the device into the textile fabric production line;

[0049] Step 3: Ultraviolet irradiation: start the ultraviolet emitter to irradiate the fabric 8 to be tested in a targeted manner;

[0050] Step 4: Initial angle adjustment: Start the first motor 753. The motor output shaft drives the gear 754 to rotate. The gear 754 drives the meshing gear ring 752, which drives the slip ring 74 to rotate in the annular groove 73 in the circular groove 71. This causes the inner rail frame 761 to rotate, and then drives the ball 722 in the top frame 721 to rotate, achieving the initial angle adjustment of the UV emitter.

[0051] Step 5: Fine angle adjustment: Start the second motor 765, which drives the first screw 762 in the inner rail frame 761 to rotate, causing the sliding block 763 to slide horizontally. The sliding block 763 drives the sleeve 7642 and the slide bar 7643 to swing, causing the top sphere 722 to rotate longitudinally while rotating itself, achieving horizontal and vertical angle adjustment of the ultraviolet light emitting lamp 723, and comprehensively testing the fabric's UV protection ability.

[0052] Step 6: Online detection is performed. The finished fabric enters the slot 4 at the input end of the box 3 and is tested in real time with the help of the UV generating mechanism 7 and the UV intensity detector 5 with adjusted angles. After the test is completed, the fabric is discharged from the discharge slot 4 and wound up by the winding device.

[0053] Principle and advantages of use: By setting the positioning mechanism 6, the practicability and accuracy of the device in the process of textile fabric detection are significantly improved. In actual operation, the fabric 8 to be tested can be conveniently placed inside the device and wrapped around the outer surface of the tensioning guide roller 64 and the guide roller 65. Specifically, the fabric 8 to be tested is introduced through the groove body 4 on one side of the box body 3 and then led out from the groove body 4 on the other side of the box body 3, forming a coherent detection path.

[0054] When the third motor 612 is started, power is transmitted to the second screw rod 613, driving it to rotate. The rotation of the second screw rod 613 causes the longitudinal movable block 614 to slide up and down in the vertical direction, thereby pushing the cross rail 622 to move up and down synchronously. In this process, the oblique movable block 623, relying on the guiding effect of the oblique rail 621, makes corresponding displacement changes along the oblique rail 621 as the cross rail 622 moves up and down. At the same time, the transverse movable block 625 keeps sliding inside the cross rail 622. The oblique movable block 623 and the transverse movable block 625 realize rotation linkage through an ingenious mechanical structure. This linkage mechanism makes the cross rail 622 move up and down. At the same time, the oblique movable block 623 can slide outward along the inclined rail 621. The sliding of the oblique movable block 623 further pushes the elastic component 63 to move downward. The downward movement of the elastic component 63 drives the two frames 632 to move downward synchronously. The downward movement of the frame 632 prompts the tensioning guide roller 64 to move downward, thereby increasing the distance between the tensioning guide roller 64 and the guide roller 65. This increase in the distance produces a pulling effect on the surrounding fabric to be tested 8, so that the fabric reaches a taut state. When the fabric is stressed, the pressure generated acts on the buffer spring 633, and the slide 634 squeezes the buffer spring 633 accordingly. The buffer spring 633 and the slide 634 work together to achieve a good buffering effect.

[0055] Through the power drive of the adjustment mechanism and the coordinated linkage of the linkage component 62, the distance between the two tensioning guide rollers 64 and the guide roller 65 can be accurately adjusted. Combined with the buffering characteristics of the elastic component 63, the device can stably stretch and tension fabrics of different elastic materials, greatly improving the detection accuracy, being suitable for the detection needs of various types of fabrics, and playing an excellent positioning function. In addition, since the tensioning guide roller 64 and the guide roller 65 are connected in a rotating manner, the device can be seamlessly integrated into the textile fabric production line. During the production process, real-time detection can be carried out with the help of the ultraviolet generating mechanism 7 and the ultraviolet intensity detector 5. The completed textile fabric enters the box 3 from the trough 4 at the input end of the box 3 for detection, and is then discharged from the trough 4 at the discharge end of the box 3 and finally wound by the winding device of the production line. This design allows the device to directly replace the tensioning mechanism of the winding device during the detection process, without the need to pre-cut the textile fabric into small pieces for detection, thus realizing real-time online detection in the production process, effectively avoiding the generation of a large number of defective products, and significantly reducing the defective rate while improving the detection efficiency.

[0056] The ultraviolet light generating mechanism 7 of the device greatly enhances its comprehensiveness and flexibility in the ultraviolet light shielding effect test. During the test, the ultraviolet light emitter is activated to irradiate the fabric 8 to be tested in a targeted manner. The ultraviolet light penetrating the fabric 8 is monitored in real time by the ultraviolet light intensity detector 5 installed on the top. The ultraviolet light intensity can be detected quickly and accurately, providing reliable data support for real-time ultraviolet protection detection.

[0057] In order to more comprehensively simulate the ultraviolet radiation conditions in different actual scenarios, the present device is designed to adjust the ultraviolet radiation angle. When the first motor 753 is started, the motor output shaft drives the gear 754 to rotate. Since the gear 754 and the gear ring 752 are meshed, as the gear 754 continues to rotate, the gear ring 752 is driven, which in turn drives the slip ring 74 to rotate in the annular groove 73 in the circular groove 71. The rotation of the slip ring 74 causes the inner rail frame 761 installed therein to generate rotational motion. The rotation of the inner rail frame 761 further drives the sphere 722 inside its top frame 721 to rotate, thereby achieving preliminary angle adjustment of the ultraviolet emitter.

[0058] On this basis, the second motor 765 is started, and the motor drives the first screw rod 762 in the inner rail frame 761 to rotate. The rotation of the first screw rod 762 causes the sliding block 763 to slide horizontally in the horizontal direction. During the horizontal sliding of the sliding block 763, the sleeve 7642 and the slide bar 7643 connected to the top thereof swing accordingly. The swing of the slide bar 7643 and the sleeve 7642 drives the top ball 722 to rotate longitudinally while rotating itself. During the entire adjustment process, the upper hinge ball 7644 and the lower hinge ball 7641 can rotate adaptively, providing sufficient rotation space for the swing of the sleeve 7642 and the slide bar 7643. At the same time, the sleeve 7642 and the slide bar 76 43 slides with each other, further enhancing the adaptability of the linkage, and through the precise sliding control of the sliding block 763, the slide bar 7643 can effectively drive the sphere 722 to rotate in all directions, and the lateral rotation of the sphere 722 can realize the lateral angle adjustment of the ultraviolet emitting lamp 723, and the longitudinal rotation of the sphere 722 further realizes the longitudinal angle adjustment of the ultraviolet emitting lamp 723. This complex and sophisticated adjustment mechanism enables the ultraviolet emitting lamp 723 to flexibly change its irradiation angle of the fabric 8 to be tested, which significantly improves the overall simulation test performance of the device during the detection process, and can comprehensively and accurately test the ultraviolet protection ability of the fabric when irradiated by ultraviolet lamps at different angles.
