Description

Technical Field

[0001] This invention relates to the field of testing instruments, specifically a xenon lamp aging test chamber. Background Technology

[0002] A xenon lamp is an electric light source that uses high-pressure xenon gas discharge to emit light. It uses a high-voltage electric field to excite xenon gas molecules, causing them to ionize and form an electric arc discharge that releases energy and emits light. It can simulate the spectrum of sunlight and closely resemble the effect of natural sunlight. Xenon lamp aging tests are conducted by simulating full-spectrum sunlight, temperature, and humidity environments to evaluate the durability of product materials under long-term outdoor exposure. They are mainly used to optimize product design, improve product quality, and meet regulatory requirements.

[0003] Powder additives used outdoors typically require xenon lamp aging tests during production to ensure their long-term stability. Xenon lamp tests can quickly predict aging conditions over several years, shortening the research and development cycle. Existing powder additive aging tests usually involve placing the powder additive on a test tray and irradiating it with a xenon lamp. However, the powder additive is piled up in the test chamber, and the powder additive in the middle position is easily blocked by the powder on the outside, resulting in insufficient light and making it difficult to ensure the accuracy of the aging test.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through a material distribution mechanism, enables two scrapers to move in a circular motion within the material tray, allowing the scrapers to scrape and stir the powder additives. During the movement of the scrapers, they also move back and forth, solving the problem of uneven illumination caused by powder accumulation and ensuring the accuracy of aging tests, thereby improving the accuracy of aging tests.

[0016] 2. This invention utilizes a shaking mechanism to cause the conical wheel to contact the arc-shaped rack on the fixed ring during the circular motion of the scraper. The arc-shaped rack drives the conical wheel to rotate, and the conical wheel causes the scraper to swing through a sliding rod, compressing the arc-shaped spring. When the conical wheel moves away from the arc-shaped rack, the arc-shaped spring causes the sliding rod to rotate back, thus resetting the scraper's swing. As a result, the scraper can swing back and forth during its movement, shaking off the powder additives adhering to the scraper, thereby achieving an automatic cleaning effect.

[0017] 3. The present invention, through the illumination mechanism, enables the rotating ring to drive multiple xenon lamp bodies to perform circular motion when the drive motor is running, thereby increasing the illumination surface of the xenon lamp bodies, avoiding the obstruction of powder additives by the scraper, and allowing the angle of the xenon lamp bodies to be adjusted, thus achieving the effect of comprehensive illumination and improving the testing efficiency of powder additives.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8The diagram shows a xenon lamp aging test chamber, which includes a chamber body 1 and a top box 2 fixedly installed on the inner wall of the top of the chamber body 1. The bottom of the top box 2 is provided with a plurality of xenon lamp bodies 3 arranged in a centrally symmetrical manner. A placement platform 4 is fixedly installed on the inner wall of the bottom of the chamber body 1. A material tray 5 is provided on the top of the placement platform 4 for loading the powder additives to be tested and conducting aging tests through the xenon lamp bodies 3. The chamber also includes a material dispersing mechanism for uniformly dispersing the powder additives in the material tray 5. The material dispersing mechanism is installed on the outside of the placement platform 4.

[0022] The dispersing mechanism includes two scrapers 6 symmetrically arranged above the placement platform 4. The scrapers 6 can disperse the powder additives. The dispersing mechanism also includes a bottom box 9 fixedly installed on the inner wall of the bottom of the box 1. The placement platform 4 is located inside the bottom box 9. A first gear ring 10 is rotatably installed on the outer side of the placement platform 4. A drive motor 11 is fixedly installed on the outer side of the bottom box 9. A first gear 12 that cooperates with the first gear ring 10 is fixedly installed at the output end of the drive motor 11, so that the drive motor 11 can drive the first gear ring 10 to rotate through the first gear 12. Two mounting rods 13 are symmetrically distributed on the inner side of the first gear ring 10. A sleeve 14 is fixedly installed at the top of the mounting rod 13. A sliding rod 15 is slidably installed on the inner side of the sleeve 14. The two scrapers 6 are respectively fixedly installed on the two... One end of the slide rod 15 allows the first toothed ring 10 to rotate, which in turn drives the sleeve 14 to move in a circular motion via the mounting rod 13. The sleeve 14, in turn, drives the scraper 6 to move synchronously via the slide rod 15, thus stirring the powder additive and solving the problem of uneven illumination caused by powder accumulation. An elastic washer 16 is fixedly installed at the end of the slide rod 15 near the scraper 6, and the end of the elastic washer 16 away from the scraper 6 is rotatably installed at the end of the sleeve 14. A spherical abutment 17 is fixedly installed at the end of the slide rod 15 away from the scraper 6. A ring frame 18 is fixedly installed on the top of the bottom box 9. Multiple centrally symmetrically distributed protrusions 19 are fixedly installed on the inner side of the ring frame 18, and both sides of the protrusions 19 are inclined structures, so that when the slide rod 15 moves in a circular motion, the spherical abutment 17... The slide rod 15 can contact the inclined surface of the protrusion 19, and use the reaction force of the protrusion 19 to push the spherical abutment 17 to move, so that the slide rod 15 can push the scraper 6 to move. It can also stretch the elastic washer 16, and when the spherical abutment 17 moves away from the protrusion 19, the elastic force of the elastic washer 16 pushes the spherical abutment 17 to contact the inner side of the ring frame 18. Thus, with the circumferential movement of the slide rod 15, the slide rod 15 can also move back and forth on the inner side of the sleeve 14, which facilitates the dispersion of powder additives and improves the mixing efficiency of powder additives. The outer side of the placement platform 4 is provided with a slot for the limiting insertion of the material tray 5. The outer side of the material tray 5 is provided with a pull groove, so that the operator can align the material tray 5 with the slot of the placement platform 4 and insert the material tray 5 into the slot of the placement platform 4. To facilitate the installation and removal of the material tray 5, two symmetrically distributed magnetic inserts 36 are fixedly installed on the outer side of the material tray 5. The slot in the placement platform 4 has insertion holes for the magnetic inserts 36 to be inserted and positioned, facilitating the fixation of the material tray 5. A sealing ring 37 is fixedly installed between the two mounting rods 13, and the sealing ring 37 is slidably installed on the top of the base box 9. The sealing ring 37 provides a seal between the base box 9 and the placement platform 4, preventing dust and impurities from entering. A second pull ring 38 is fixedly installed between the bottom ends of the two mounting rods 13. A collar 39 is slidably installed on the outer side of the second pull ring 38. Multiple centrally symmetrically distributed second electric telescopic rods 40 are fixedly installed at the bottom of the collar 39, allowing the collar 39 to move via the second electric telescopic rods 40.The collar 39, via the second pull ring 38, drives the mounting rod 13 to move vertically up and down, facilitating height adjustment of the scraper 6. This allows the scraper 6 to move inside or above the material tray 5, facilitating its removal. A limiting ring 41 is fixedly mounted on the outer side of the mounting rod 13, positioned above the first toothed ring 10. This ensures that when the mounting rod 13 moves downwards, the limiting ring 41 contacts the top of the sealing ring 37, providing limitation and support for the movement of the mounting rod 13.

[0023] Example 2: Please refer to Figures 3-6 This embodiment further illustrates Example 1. The shaking mechanism shown in the figure includes a rotating drum 7 disposed outside the scraper 6. The rotating drum 7 enables the scraper 6 to oscillate back and forth. The shaking mechanism also includes a conical wheel 20 fixedly installed at one end of the rotating drum 7. A positioning disk 21 is fixedly installed at the end of the sleeve 14 away from the elastic washer 16. The end of the rotating drum 7 away from the conical wheel 20 is rotatably installed on the outside of the positioning disk 21. A fixing ring 22 is fixedly installed at the bottom of the ring frame 18. Multiple arc-shaped racks 23 distributed centrally symmetrically are fixedly installed on the outside of the fixing ring 22. The conical wheel 20 cooperates with the adjacent arc-shaped racks 23. The inner side of the conical wheel 20 has a prismatic structure, and the inner side of the conical wheel 20 is slidably installed on the outside of the slide rod 15. When the sleeve 14 moves, it can drive the rotating drum 7 to move through the positioning disk 21. The rotating drum 7 drives the conical wheel 20 to contact the arc-shaped racks 23 on the fixing ring 22, so that the arc-shaped racks 23 are slidably installed on the outside of the slide rod 15. The rack 23 drives the conical wheel 20 to rotate, which in turn drives the slide rod 15 to rotate, causing the slide rod 15 to swing the scraper 6. Two centrally symmetrically distributed sliding sleeves 24 are fixedly installed on the outer side of the rotating cylinder 7. An arc-shaped groove is provided on the outer side of the positioning plate 21 for the sliding sleeves 24 to be limited and slid. When the rotating cylinder 7 rotates, it can drive the sliding sleeves 24 to move along the inner side of the arc-shaped groove. An arc-shaped rod 25 is fixedly installed on the inner side of the arc-shaped groove. The arc-shaped rod 25 slides through the sliding sleeve 24, allowing the sliding sleeve 24 to move along the outer side of the arc-shaped rod 25, providing guidance and support for the movement of the sliding sleeve 24. An arc-shaped spring 26 is fixedly installed between the sliding sleeve 24 and the inner side of the arc-shaped groove. During the movement of the sliding sleeve 24, the arc-shaped spring 26 can be compressed. When the conical wheel 20 moves away from the arc-shaped rack 23, the rebound force of the arc-shaped spring 26 can be used to make the conical wheel 20 rotate and reset, realizing the reciprocating swing of the scraper 6.

[0024] Example 3: Please refer to Figure 2 , Figure 7 and Figure 8This embodiment further illustrates other embodiments. The illumination mechanism shown in the figure includes a rotating ring 8 rotatably mounted inside the top box 2. The rotating ring 8 can cause multiple xenon lamp bodies 3 to rotate and shift. The illumination mechanism also includes a suspension rod 27 fixedly mounted on the top of the xenon lamp body 3. The suspension rod 27 is hinged to the bottom of the rotating ring 8. Two symmetrically distributed slide rails 28 are fixedly mounted on the top of the xenon lamp body 3. A pulley rod 29 is slidably mounted between the two slide rails 28. Multiple centrally symmetrically distributed first electric telescopic rods 30 are fixedly mounted inside the top box 2. A first pull ring 31 is fixedly mounted between the bottom ends of the multiple first electric telescopic rods 30. A sleeve block 32 is rotatably mounted on the outer side of the first pull ring 31. A connecting rod 33 is fixedly mounted between the outer side of the sleeve block 32 and the pulley rod 29, so that the first electric telescopic rod 30 can drive the sleeve block 32 to move vertically up and down through the first pull ring 31. The sleeve block 32 can move synchronously with the pulley rod 29 through the connecting rod 33. The pulley rod 29 can... The xenon lamp body 3 is swung around the suspension rod 27 by the slide rail 28, which facilitates the adjustment of the angle of the xenon lamp body 3. The output end of the drive motor 11 is rotatably installed inside the top box 2, and the output end of the drive motor 11 is fixedly installed with a second gear 34. The outer side of the rotating ring 8 is fixedly installed with a second gear ring 35 that cooperates with the second gear 34, so that the drive motor 11 can drive the second gear ring 35 to rotate through the second gear 34. The second gear ring 35 drives the xenon lamp body 3 to make a circular motion through the rotating ring 8 and the suspension rod 27, so as to achieve full irradiation of the powder additive. The top of the top box 2 is fixedly installed with a telescopic tube 42, and the outer side of the xenon lamp body 3 is fixedly installed with a water cooling tube 43. The water cooling tube 43 is connected to the telescopic tube 42 through the sleeve block 32. The outer side of the box 1 is installed with a radiator. The telescopic tube 42 is connected to the radiator through the box 1, so that the radiator circulates coolant to the water cooling tube 43 through the telescopic tube 42. The water cooling tube 43 can dissipate heat from the xenon lamp body 3.

[0025] Working principle: First, the operator opens the door of the housing 1, pulls the material tray 5 out of the placement platform 4, pours in the powder additive to be tested, and then inserts the material tray 5 into the slot of the placement platform 4. Next, the operator activates the second electric telescopic rod 40, causing the second electric telescopic rod 40 to pull the second pull ring 38 downwards. The second pull ring 38 pulls the collar 39 downwards, and the collar 39 drives the mounting rod 13 downwards, causing the mounting rod 13 to pull the sleeve 14 downwards. This causes the sleeve 14 to bring the scraper 6 at the end of the sliding rod 15 into contact with the powder additive in the material tray 5. Then, the operator starts the drive motor 11, causing the drive motor 11 to drive the first gear 12 and the second gear 34 to rotate synchronously. The first gear 12 drives the first gear ring 10 to rotate synchronously, causing... The first toothed ring 10 drives the two mounting rods 13 to perform circular motion. The mounting rods 13 drive the sliding rods 15 inside the sleeve 14 to move synchronously, so that the sliding rods 15 stir and disperse the powder additives in the material tray 5 through the scraper 6. At the same time, the sliding rods 15 drive the spherical abutment 17 to move along the inner side of the ring frame 18. When the spherical abutment 17 contacts the inclined surface of the protrusion 19, the reaction force of the protrusion 19 pushes the spherical abutment 17 to move. The spherical abutment 17 pushes the sliding rod 15 to move along the inner side of the conical wheel 20 and the inner side of the sleeve 14, and pushes the scraper 6 to move. At the same time, the sliding rod 15 stretches the elastic washer 16. As the spherical abutment 17 moves, it slides off the protrusion 19. The rebound force of the elastic washer 16 pulls the sliding rod 15 along the sleeve. The inner side of the sleeve 14 returns to its original position, causing the slide rod 15 to push the spherical block 17 into contact with the inner side of the ring frame 18. Thus, with the circular motion of the slide rod 15, it can reciprocate left and right within the sleeve 14. The scraper 6 disperses the powder additives. Simultaneously, the sleeve 14 drives the rotating cylinder 7 to move synchronously via the positioning plate 21. The rotating cylinder 7 drives the conical wheel 20 to move synchronously. When the conical wheel 20 contacts the arc-shaped rack 23 on the fixed ring 22, the arc-shaped rack 23 drives the conical wheel 20 to rotate. The conical wheel 20 drives the slide rod 15 and the rotating cylinder 7 to rotate. The slide rod 15 drives the scraper 6 to swing. Furthermore, the rotating cylinder 7 drives the sliding sleeve 24 to move along the arc-shaped groove of the positioning plate 21, compressing the arc-shaped spring 26. Subsequently, the conical wheel 20 moves away from the current arc... The rack and pinion 23, using the rebound force of the arc spring 26, moves the sliding sleeve 24 back to its original position. The conical wheel 20 drives the sliding rod 15 to rotate back to its original position, causing the scraper 6 to swing back. Thus, the scraper 6 can also oscillate back and forth during its circular motion, facilitating the shaking off of the powder additives adhering to the scraper 6. The powder additives can then be evenly distributed in the material tray 5 and are in a flowing state. At the same time, the second gear 34 drives the second gear ring 35 to rotate, and the second gear ring 35 drives the rotating ring 8 to rotate synchronously. The rotating ring 8 drives multiple xenon lamp bodies 3 to perform circular motion through the suspension rod 27, providing comprehensive irradiation of the powder additives and preventing the scraper 6 from obstructing the powder additives. Thus, the xenon lamp bodies 3 can comprehensively test the powder additives, solving the problem of powder additive accumulation.This achieves comprehensive and accurate testing, ensuring the precision of powder additive testing.
