[0050] Embodiment

[0051] Referring to Figure 1-8 , an anti-ultraviolet test device, comprising a machine case 1, a fixing table 2, a pressing head 3, a test table 4, a PMMA plate 5, a light source mechanism 6, a light source collection mechanism 7, and a computer 8;

[0052] The fixing table 2 is fixed on the front side of the machine case 1 for placing a sample to be tested 100; the pressing head 3 is arranged on the front side of the machine case 1, above the fixing table 2, and can move up and down; the test table 4 is detachably mounted on the fixing table 2. The test table 4 includes a partition plate 41 and two support seats 42. The two support seats 42 are respectively fixed on both sides of the bottom of the partition plate 41. A light-transmitting hole 411 is provided on the partition plate 41; the PMMA plate 5 is used for placing on the fixing table 2 after applying cosmetics; the light source mechanism 6 is fixed in the pressing head 3 for emitting ultraviolet light to irradiate the sample to be tested 100; the light source collection mechanism 7 is fixed in the fixing table 2 for collecting the ultraviolet light passing through the sample to be tested 100; the computer 8 is used for controlling the switch of the light source mechanism 6 and the up and down movement of the pressing head 3, and receiving the data collected by the light source collection mechanism 7.

[0053] This utility model can not only perform the anti-ultraviolet performance test of textiles, but also perform the anti-ultraviolet performance test of cosmetics.

[0054] When the sample to be tested 100 is a textile and the anti-ultraviolet performance test of the textile is carried out, the test bench 4 and the PMMA plate 5 are not needed. The textile is directly placed on the fixing table 2, the pressing head 3 moves downwards and buckles the textile. The textile is buckled by the pressing head 3 to prevent the leakage of ultraviolet light, and then the test starts. The light source mechanism 6 emits ultraviolet light to irradiate the textile. The light source mechanism 6 collects the ultraviolet light passing through the textile and transmits it to the computer 8 in the form of data. After receiving the data collected by the light source mechanism 6, the computer 8 converts it into the ultraviolet protection coefficient UPF value, the ultraviolet transmittance T(UVA) and T(UVB), and finally displays the test results and saves the data.

[0055] When the sample to be tested 100 is a cosmetic and the anti-ultraviolet performance test of the cosmetic is carried out, the test bench 4 and the PMMA plate 5 are needed. The test bench 4 is installed on the fixing table 2 through its support seat 42. There is a placement space between the fixing table 2 and the isolation plate 41. Then, the cosmetic is applied on the PMMA plate 5, and the PMMA plate 5 is placed into the above space. The pressing head 3 presses downwards and buckles the isolation plate 41 to prevent the leakage of ultraviolet light, and then the test starts. The light source mechanism 6 emits ultraviolet light. The ultraviolet light passes through the light-transmitting hole 411 on the isolation plate 41 and then irradiates the cosmetic. The light source mechanism 6 collects the ultraviolet light passing through the cosmetic and transmits it to the computer 8 in the form of data. After receiving the data collected by the light source mechanism 6, the computer 8 converts it into the ultraviolet protection coefficient SPF value, the ultraviolet transmittance T(UVA) and T(UVB), and finally displays the test results and saves the data.

[0056] The PMMA plate 5 can carry the cosmetic, avoiding the direct contact between the cosmetic and the fixing table 2. The test bench 4 can isolate the pressing head 3 from the cosmetic, avoiding the direct contact between the cosmetic and the pressing head 3, thus ensuring the accuracy of the test results. If the cosmetic directly contacts the fixing table 2 and the pressing head 3, the cosmetic will adhere to the fixing table 2 and the pressing head 3, causing pollution to them and seriously affecting the test results.

[0057] Of course, when testing textiles, the test bench 4 can also not be disassembled, and the textile can be directly placed on the isolation plate 41 for testing.

[0058] In a specific implementation scheme, a plurality of positioning holes 412 are provided on the isolation plate 41, and alignment holes 51 for aligning with the positioning holes 412 are provided on the PMMA plate 5.

[0059] In this embodiment, the isolation plate 41 has a size of 10 cm × 8 cm, and six positioning holes 412 are arranged in an array thereon. When moving the PMMA plate 5, the alignment holes 51 on the PMMA plate 5 are aligned with different positioning holes 412, so that the ultraviolet protection performance of cosmetics at different positions can be accurately tested.

[0060] In a specific implementation, it further includes an extension plate 9, and the extension plate 9 is detachably installed on the fixed table 2, and the area of the extension plate 9 is larger than that of the fixed table 2.

[0061] In this embodiment, the extension plate 9 has a size of 25 cm × 15 cm. Since the extension plate 9 has a large area, it is convenient to lay the textile flat, avoiding wrinkles on the textile and affecting the test results.

[0062] In a specific implementation, a first filter 10 is fixed to the bottom of the indenter 3, and a second filter 11 is fixed to the top of the fixed table 2. During the test, the sample to be tested 100 is evenly sealed and pressed in the space opposite to the first filter 10 and the second filter 11. The first filter 10 and the second filter 11 can be used to filter deep ultraviolet light (ultraviolet light below 250 nm) and visible light respectively, ensuring the accuracy of the test results.

[0063] In a specific implementation, the light source mechanism 6 includes an ultraviolet lamp 61 and a power supply 62 connected to each other, and the power supply 62 is connected to the computer 8 through a control board 12.

[0064] In a specific implementation, the indenter 3 is driven to move up and down by a motor 13, and the motor 13 is connected to the computer 8 through a control board 12.

[0065] In a specific implementation, the light source acquisition mechanism 7 includes an integrating sphere 71, a monochromator 72 and a photomultiplier tube 73 connected in sequence, and the photomultiplier tube 73 is connected to the computer 8 through a control board 12.

[0066] The integrating sphere 71 is used to collect the ultraviolet light passing through the sample to be tested 100. The monochromator 72 selects a grating monochromator 72 to decompose the ultraviolet part in the ultraviolet light, and the photomultiplier tube 73 is used to amplify the ultraviolet part decomposed by the monochromator 72.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
