Description

Technical Field

[0001] This application relates to the field of fabric testing equipment technology, and in particular to a sun protection testing device for UV-resistant fabrics. Background Technology

[0002] Ultraviolet (UV) radiation is the primary target of sun protection. People can reduce their exposure to UV rays by wearing sun-protective clothing. The sun protection performance of such clothing largely depends on the fabric used, as different fabrics have different UV-blocking efficiencies. To determine a fabric's UV-blocking ability, testing is required. Existing testing equipment typically includes a light source of a specific power and a sensor probe. The probe first senses the UV intensity of the light source and then places it behind the fabric to test the UV intensity after it is blocked. While this method can roughly determine the UV-blocking efficiency, it is easily affected by ambient light, resulting in significant testing errors. Summary of the Invention

[0003] The purpose of this application is to provide a sun protection testing device for UV-resistant fabrics with higher detection accuracy.

[0004] To achieve the above objectives, this application provides a sun protection testing device for UV-resistant fabrics: including a base, a light transmittance sensor disposed on the upper surface of the base, a support platform disposed above the base for pressing the fabric body against the upper surface of the base, the support platform being open in the middle, a light source intensity sensor disposed on the inner bottom surface of the support platform, and a light cover disposed above the support platform for blocking the open upper end of the support platform while generating ultraviolet rays, which can effectively avoid the influence of external natural light.

[0005] As a preferred embodiment, the base includes a configuration disk, and a temperature sensor is fixedly connected to the upper surface of the configuration disk. There are several light transmittance sensors, all of which are fixedly connected to the upper surface of the configuration disk to detect the intensity of the remaining ultraviolet light after the light source is blocked.

[0006] As a preferred embodiment, the edge of the configuration plate is fixedly connected to a lower magnetic ring, and the bottom of the support platform is an upper magnetic ring, which is suitable for approaching and being attracted to the lower magnetic ring to achieve a clamping function.

[0007] As a preferred embodiment, the inner wall of the upper magnetic ring is fixedly connected to an ear plate, and there are several light source intensity sensors, all of which are fixedly connected to the upper surface of the ear plate; the bottom surface of the configuration plate is fixedly connected to a support leg, which allows the configuration plate to be suspended at a certain height above the placement surface.

[0008] As a preferred embodiment, the edge of the upper magnetic ring is fixedly connected to a positioning hopper, the light cover includes a shielding disc, the lower surface of the shielding disc is fixedly connected to an inner platform, which is suitable for sinking into the positioning hopper, and the bottom surface of the inner platform is provided with an ultraviolet light source for exciting ultraviolet light.

[0009] As a preferred embodiment, a handle and a power distribution box are fixedly connected to the upper surface of the light-shielding disc, and a switch is provided on the power distribution box to control the power supply to and from the ultraviolet light source.

[0010] As a preferred embodiment, the outer side of the positioning bucket has a support plate, which is located near the upper end of the positioning bucket to share the pressure of the photomask borne by the upper end of the positioning bucket.

[0011] As a preferred embodiment, both the light source intensity sensor and the light transmittance sensor are ultraviolet sensors. A processor is also fixedly connected to the bottom surface of the configuration disk. The light source intensity sensor, temperature sensor, and light transmittance sensor are all electrically connected to the processor, thereby realizing centralized data processing.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By setting multiple light source intensity sensors on the upper part of the fabric, the intensity of ultraviolet light source can be detected at multiple locations, which can effectively reduce the detection error of the initial light intensity; by setting multiple light transmission intensity sensors on the lower part of the fabric, the detection error of the remaining light intensity can be effectively reduced, and the accuracy of the ultraviolet light transmittance to the fabric will be relatively high.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] like Figure 1-8 The UV-resistant fabric sun protection testing device shown includes a base 3 at the bottom. A light transmittance sensor 306 is installed on the upper surface of the base 3. The light transmittance sensor 306 is an ultraviolet sensor used to detect the remaining ultraviolet intensity after passing through the fabric 4. The specific structure of the base 3 includes a closed configuration disk 301. The upper and lower surfaces of the configuration disk 301 are not perforated or connected. A temperature sensor 305 is also fixedly connected to the upper surface of the configuration disk 301. The detection probe of the temperature sensor 305 is usually in direct contact with the fabric 4 to detect the temperature rise of the fabric 4 under ultraviolet light irradiation. There are several light transmittance sensors 306, all fixedly connected to the upper surface of the configuration disk 301. In this embodiment, only one temperature sensor 305 is provided, located in the center of the upper surface of the configuration disk 301, while all the light transmittance sensors 306 are evenly arranged around the temperature sensor 305. Simultaneous detection by multiple light transmittance sensors 306 can effectively reduce the error in light transmittance data acquisition.

[0029] A support platform 2 is provided above the base 3 to press the fabric 4 firmly against the upper surface of the base 3, so that the fabric 4 can be flattened to receive ultraviolet light. The edge of the configuration tray 301 is fixedly connected to a lower magnetic ring 303, while the bottom of the support platform 2 is an upper magnetic ring 203, which will be attracted when it is close to the lower magnetic ring 303. In actual configuration, only one of the upper magnetic ring 203 and the lower magnetic ring 303 needs to be magnetic, and the other is made of a magnetically attractive material to achieve the adsorption function. The bottom surface of the configuration tray 301 is also fixedly connected to a support leg 302. There are generally no less than three support legs 302, which are used to suspend the configuration tray 301 at a certain height above the placement surface.

[0030] The center of the support platform 2 is open, allowing ultraviolet light to irradiate from top to bottom. A light source intensity sensor 205 is installed on the inner bottom surface of the support platform 2. A light transmission intensity sensor 306, also an ultraviolet sensor, is used to directly detect the intensity of the ultraviolet light generated by the light source. Ear plates 204 are fixedly connected to the inner wall of the upper magnetic ring 203. The ear plates 204 can be integrally formed with the upper magnetic ring 203, or they can be made of different materials and connected and fixed with a curing adhesive. There are several ear plates 204, which are arranged around... The upper magnetic rings 203 are arranged equidistantly along their axes. There are also several light source intensity sensors 205. These light source intensity sensors 205 are all fixedly connected to the upper surface of the ear plate 204. The light source intensity sensors 205 correspond one-to-one with the ear plate 204. The bottom surface of the configuration disk 301 is also fixedly connected to the processor 304. The light source intensity sensors 205, temperature sensors 305 and light transmission intensity sensors 306 are all electrically connected to the processor 304. The processor 304 acquires and records the detection data for subsequent comparison.

[0031] A light cover 1 is installed above the support platform 2. The light cover 1 is used to block the open upper end of the support platform 2 and generate ultraviolet light. Specifically, a positioning bucket 201 is fixedly connected to the edge of the upper magnetic ring 203. The positioning bucket 201 is larger at the upper end and smaller at the lower end, and its inner wall is an inverted frustum shape. The light cover 1 includes a non-perforated shielding disc 101. The diameter of the shielding disc 101 is larger than the outer diameter of the upper end of the positioning bucket 201. An inset platform 105 is fixedly connected to the lower surface of the shielding disc 101. The inset platform 105 is also an inverted frustum shape and is perfectly recessed into the positioning bucket 201. The outer side of the inset platform 105 fits against the inner wall of the positioning bucket 201, thereby achieving a precise fit. The outer side of the positioning bucket 201 has a support plate 202. The upper surface of the support plate 202 is usually horizontal and the support plate 202 is close to the upper end of the positioning bucket 201. Furthermore, the upper surface is flush with the upper end of the positioning bucket 201 and together they contact the lower surface of the light shielding disc 101, which can disperse the pressure. An even more important function of the support plate 202 is as a force-bearing part. Because the support plate 202 protrudes from the outer side of the positioning bucket 201, when it is necessary to remove the support plate 2 from the pressed fabric body 4, the entire support plate 2 can be easily lifted by grasping the support plate 202. The bottom surface of the embedded platform 105 is provided with an ultraviolet light source 106 for generating ultraviolet rays. The upper surface of the light shielding disc 101 is fixedly connected with a handle 102 and a power distribution box 103. The light shield 1 can be easily picked up by holding the handle 102. The power distribution box 103 is used to connect an external power cord to supply power to the ultraviolet light source 106. The power distribution box 103 is also provided with a switch 104 for controlling the power supply of the ultraviolet light source 106.

[0032] Working principle: In use, first place the base 3 on a horizontal platform. The base 3 can be fixed to the platform using the connector. Then, lay the fabric 4 flat on the upper surface of the lower magnetic ring 303. The fabric 4 will cover the temperature sensor 305 and all the light transmission intensity sensors 306. Then, place the support platform 2 on top of the base 3. The upper magnetic ring 203 will automatically approach and clamp the lower magnetic ring 303, thereby clamping the spread fabric 4. Next, use the handle 102 to attach the light cover 1 to the support platform 2. At this time, the part of the fabric 4 located inside the test device is in a completely dark environment on both the upper and lower surfaces. Finally, press the power distribution box. Switch 104 on 103 powers on the ultraviolet light source 106, which then emits ultraviolet light directly onto the fabric 4. All light source intensity sensors 205 detect the initial ultraviolet intensity of the light source and record it with the processor 304. All light transmission intensity sensors 306 detect the ultraviolet intensity that has passed through the fabric 4 and record it with the processor 304 as well. By comparing the initial average value of the ultraviolet light with the average value of the transmitted light, the blocking efficiency of the fabric against ultraviolet light can be obtained. At the same time, the processor 304 also records the rate of temperature rise of the fabric 4 under the irradiation conditions through the temperature sensor 305, thereby comprehensively judging the sun protection performance of the ultraviolet-proof fabric.
