[0023] A sunscreen composition obtained by a method for preparing a sunscreen composition, wherein the sunscreen composition is applied in cosmetics.

[0024] Working principle: When the staff prepares the sunscreen composition, first, the staff connects the sampling tube containing the sunscreen composition sample with the injection tube 2, injects the sample into the injection tube 2, and the sample passes through the injection tube 2 and falls on the detection plate 7 directly below the injection tube 2. At this time, the driving motor 6 is running, so that the driving motor 6 drives the rotating rod 3 to rotate, and the two rollers 5 on the rotating rod 3 cooperate with the two rollers 5 on the other rotating rod 3 to drive the two conveyor belts 4 to rotate and move, so that the conveyor belt 4 drives the support rod 10 to move synchronously, and the support rod 10 drives the detection plate 7 to leave the bottom of the injection tube 2 through the installation tube 9 and the fixed plate 8, and moves toward the scraper 11.

When the detection plate 7 is close to the scraper 11, as the detection plate 7 moves, the bottom end of the scraper 11 can smooth the sample. Then, the detection plate 7 moves to the bottom of the ultraviolet light box 12, so that the ultraviolet light box 12 When the conveyor belt 4 drives the support rod 10 to move to the right side of the conveyor belt 4, the guide slide bar 14 can move from the slide rail 15 to the slide rail 2 16, so that the guide slide bar 14 moves along the inner side of the slide rail 2 16, and the distance between the slide rail 2 16 and the bottom of the conveyor belt 4 is used to make the guide slide bar 14 drive the installation tube 9 to move along the outer side of the limit block 17 on the support rod 10, and compress the tension spring 18, and the installation tube 9 drives the detection plate 7 to move synchronously through the fixed plate 8, so that the detection plate 7 can be inserted into the water in the water tank 13, and finally, the conveyor belt 4 transports the detection plate 7, and the sunscreen composition sample on the detection plate 7 can be cleaned, thereby, multiple detection plates 7 can be recycled, and the staff only needs to inject samples into the injection tube 2 in sequence to detect multiple samples, thereby achieving the effect of continuous detection and improving the production efficiency of the sunscreen composition.

[0025] Example 2: Please refer to Figure 2 , Figure 7 and Figure 5, this embodiment is a further explanation of the first embodiment. The cleaning brush assembly shown in the figure includes four mounting rods 19 rotatably mounted on the inner side of the water storage tank 13 in an equidistant distribution. A sleeve 20 is arranged on the outer side of the mounting rod 19. A cleaning brush 35 is fixedly mounted on the outer side of the sleeve 20 for cleaning the sunscreen composition sample on the surface of the detection plate 7. A synchronous belt 1 21 located on the outer side of the water storage tank 13 is rotatably mounted between the four mounting rods 19. When any mounting rod 19 rotates, the synchronous belt 1 21 can drive the other three mounting rods 19 to rotate synchronously. A synchronous belt 22 is rotatably mounted between the leftmost mounting rod 19 and the adjacent rotating rod 3. The synchronous belt 22 is located on the outer side of the housing 1. When the rotating rod 3 rotates, the corresponding mounting rod 19 can be driven to rotate synchronously through the synchronous belt 22. A plurality of sliding strips 23 equidistantly mounted are fixedly mounted on the outer side of the sleeve 20. The outer side of 19 is provided with a sliding groove for the sliding bar 23 to limit the sliding of the sliding bar 23, so that the installation rod 19 drives the sleeve 20 to rotate through the sliding bar 23. The outer side of the installation rod 19 is provided with an annular frame 24, and the annular frame 24 is fixedly installed on the inner side of the water storage tank 13. A plurality of top blocks 25 distributed symmetrically with the center are fixedly installed on the side of the sleeve 20 close to the annular frame 24. A slot for the top block 25 to limit the insertion is provided on the outer side of the annular frame 24. The width of the slot is greater than the width of the top block 25. The outer side of the top block 25 and the inner side of the slot are both corresponding arc structures, so that the top block 25 can be inserted into the slot, and as the sleeve 20 rotates, the top block 25 is moved out of the slot. A retaining ring 26 is provided on the side of the sleeve 20 away from the top block 25, and a plurality of spring rods 27 distributed symmetrically with the center are fixedly installed between the retaining ring 26 and the inner side of the water storage tank 13, so that the retaining ring 26 can push the sleeve 20 to reset.

[0026] In this embodiment, when the rotating rod 3 rotates, the corresponding mounting rod 19 can be driven to rotate synchronously through the synchronous belt 22, so that the mounting rod 19 drives the other three mounting rods 19 to rotate synchronously through the synchronous belt 1 21, and the slide groove on the mounting rod 19 drives the slide bar 23 on the sleeve 20 to rotate, so that the slide bar 23 drives the sleeve 20 to rotate synchronously, and the sleeve 20 can use the cleaning brush 35 to cooperate with the water in the water storage tank 13 to clean the sunscreen composition sample on the detection plate 7, and when the sleeve 20 rotates, the sleeve 20 can drive the top block 25 to make a circular motion with the mounting rod 19 as the center, and the arc surface of the top block 25 can move along The arc-shaped slot on the annular frame 24 slides out, and the reaction force of the top block 25 is used to make the top block 25 push the sleeve 20 and the slide bar 23 to move along the outer side of the mounting rod 19 and the inner side of the slide groove respectively. The sleeve 20 can resist the retaining ring 26 to compress the spring rod 27. When the top block 25 is aligned with the slot on the annular frame 24, the rebound force of the spring rod 27 can be used to allow the top block 25 to be inserted into the slot. As a result, the sleeve 20 can reciprocate along the outer side of the mounting rod 19 while rotating, so that the cleaning brush 35 can comprehensively clean the sunscreen composition sample on the detection plate 7, thereby improving the cleaning efficiency of the detection plate 7.

[0028] In this embodiment: the staff can quickly install the scraper 11 through the knife holder 28, and the detection plate 7 can drive the arc scraper strip 31 to move synchronously when it moves. When the arc scraper strip 31 contacts the scraper 11, the arc scraper strip 31 can move along the outer side of the scraper 11, scrape out the sample remaining on the outer side of the scraper 11, and push the scraper 11 to move along the insertion cavity of the knife holder 28. The scraper 11 drives the coil spring 30 to contract through the positioning rod 29. When the arc scraper strip 31 is away from the scraper 11, the rebound force of the coil spring 30 is used to rotate and reset the scraper 11 to maintain the cleanliness of the scraper 11. The staff can adjust the ultraviolet light box 12 through the monitoring host 32 and observe the detection status of the sunscreen composition sample.
