Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paint detection, in particular to a rare earth reflective heat insulation refrigeration coating reflective heat insulation performance detection equipment. BACKGROUND

[0002] Reflective heat insulation coating is a high-efficiency energy-saving coating made of synthetic resin as base material and functional fillers and additives. It can reduce temperature through three mechanisms of reflecting 400-2500nm range of solar radiation, radiating heat and hollow microsphere heat insulation. The rare earth reflective heat insulation refrigeration coating is a high-performance energy-saving coating based on reflective heat insulation coating technology and introducing rare earth materials as functional fillers. It can achieve cooling effect through multiple mechanisms such as reflecting solar radiation, radiating heat and hollow microsphere heat insulation. The core principle of the coating is to achieve efficient heat insulation through multiple mechanisms. It can reflect 400-2500nm band of solar infrared and ultraviolet light, enhance the heat radiation and heat dissipation capacity by using rare earth doped metal oxides and other materials, and insulate heat conduction by hollow microspheres, thereby reducing the surface temperature of the object by more than 20℃. Its performance needs to meet the requirements of national standards, such as solar reflectance not less than 85%, hemispherical emittance not less than 83%. In terms of composition and classification, the rare earth reflective heat insulation coating is made of synthetic resin as base material, adding rare earth functional fillers, heat reflective pigments and additives, which belongs to the subdivision type of heat reflective heat insulation coating, and together with barrier type and radiation type coatings forms the heat insulation coating system.

[0003] When detecting the reflective heat insulation performance of the rare earth reflective heat insulation refrigeration coating, accurate and efficient operation is crucial to obtain reliable detection results. However, the existing detection process faces many problems. On the one hand, in the coating application process, the traditional method cannot guarantee that the rare earth reflective heat insulation refrigeration coating is evenly applied on the coating detection sheet. Uneven application will lead to inconsistent coating thickness, which will affect the accurate evaluation of the heat insulation effect of the coating. Due to the lack of effective control means, it is difficult to achieve the uniformity and controllability of the coating application, which makes the detection results easily disturbed by the application quality, reducing the accuracy and reliability of the detection results. On the other hand, when detecting the heat insulation effect, simulating different light conditions is the key to fully evaluate the performance of the coating. However, the existing equipment often cannot flexibly adjust the distance and intensity of the light, making it difficult to truly simulate the complex and changeable light conditions in the actual use environment. Moreover, the light simulation of different spectra also has deficiencies, which cannot meet the needs of fully detecting the reflective heat insulation performance of the coating under different light conditions, resulting in a limited detection range of the coating performance and difficulty in fully tapping the potential performance of the coating.

[0004] Therefore, based on the above problems, we have invented a rare earth reflective heat insulation refrigeration coating reflective heat insulation performance detection equipment. SUMMARY

Then, in conjunction with the coating mechanism, the coating motor drives the external meshing wheel, residual tooth ring and other components to rotate the coating roller, realizing automatic coating of the coating test sheet surface. The whole process does not require cumbersome manual operation, which significantly improves the efficiency and quality of coating.

[0018] 4. Through the position adjustment mechanism and the position adjustment motor, the spotlight can move in multiple directions via a series of gears. By adjusting the position of the spotlight, different distances and intensities of light can be simulated. Different spotlights can also be replaced to simulate different spectral irradiation. This greatly expands the testing range of the reflective heat insulation performance of rare earth reflective heat insulation and cooling coatings, making them closer to the actual use environment and the test results more representative.

[0031] 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.

[0032] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a device for testing the reflective heat insulation performance of rare earth reflective heat insulation and cooling coatings.

[0033] like Figures 1-10 As shown, a rare earth reflective heat insulation and cooling coating reflective heat insulation performance testing device includes a base 1, a front cylinder 2 and a rear cylinder 3 on the base 1, both the front cylinder 2 and the rear cylinder 3 are fixedly installed on the base 1 by brackets 4, and each of the lower ends of the front cylinder 2 and the rear cylinder 3 is embedded with a fixing post 14. A partition plate 58 is installed between the front cylinder 2 and the rear cylinder 3, and two mounting plates 19 are provided between the front cylinder 2 and the rear cylinder 3. A coating test piece 21 is installed inside the mounting plate 19, and an arc-shaped cover plate 20 is fixedly connected to the outside of the mounting plate 19. A space is provided between the two fixing posts 14 for opening the two mounting plates 19. The opening and closing mechanism 23 is connected. Temperature sensors 59 for detecting the surface temperature of the paint detection piece 21 are installed on the inner walls of the front cylinder 2 and the rear cylinder 3. The rear cylinder 3 is provided with a spreading mechanism 27 for spreading the paint evenly. The rear cylinder 3 is provided with a fine-tuning mechanism 41 for applying paint to the paint detection piece 21. A front cover plate 5 is rotatably installed at one end of the rear cylinder 3. Multiple spotlights 6 are installed on the front cover plate 5 near the front cylinder 2. The front cover plate 5 is provided with a position adjustment mechanism 7 for adjusting the position of the spotlights 6. The rear cylinder 3 and the front cover plate 5 are connected by multiple pins 57.

[0034] To allow the mounting plate 19 to open and close, an opening and closing mechanism 23 is provided. The opening and closing mechanism 23 includes a collection ring 15 fixedly installed to the fixed post 14. A fixed baffle 16 is fixed to the end of the collection ring 15 away from the fixed post 14. A forward shaft 17 is rotatably installed to the end of the fixed baffle 16 away from the collection ring 15. A reverse shaft 18 is rotatably installed to the end of the forward shaft 17 away from the fixed baffle 16. The reverse shaft 18 is rotatably installed to another fixed post 14. The two mounting plates 19 are fixedly connected to the forward shaft 17 and the reverse shaft 18 respectively via a connecting plate 38. Two rotating shafts 24 are rotatably installed between the fixed baffle 16 and the fixed post 14. 4. Reverse gears 25 are coaxially mounted on both shafts 17 and 18. The two reverse gears 25 are meshed together. The forward shaft 17 and the reverse shaft 18 are provided with annular tooth grooves that mesh with the two reverse gears 25 respectively. It should be noted that there is a gap between the forward shaft 17 and the reverse shaft 18. The two reverse gears 25 are staggered and the meshing position is within the gap. The fixed column 14 is embedded with an opening and closing motor 26. The drive shaft of the opening and closing motor 26 rotates through the fixed column 14 and is coaxially mounted with the rotating shaft 24. The lower end of the fixed column 14 is connected to two outflow pipes 40. The two outflow pipes 40 are connected to two collection holes 22 through two flow holes 39 respectively.

[0035] Through the above technical features: the drive shaft of the opening and closing motor 26 drives two reverse gears 25 to rotate relative to each other. The two reverse gears 25 drive the forward shaft 17 and the reverse shaft 18 to rotate in the opposite direction, respectively. The forward shaft 17 and the reverse shaft 18 drive two mounting plates 19 to rotate relative to each other through two connecting plates 38. The mounting plates 19 drive the coating detection piece 21 to rotate, so that the mounting plates 19 can be opened and closed. When opened, rare earth reflective heat insulation and cooling coating is applied to the coating detection piece 21. When closed, the heat insulation effect of the rare earth reflective heat insulation and cooling coating can be tested. The application of rare earth reflective heat insulation and cooling coating is relatively simple.

[0036] To evenly apply the rare earth reflective heat-insulating and cooling coating onto the coating test piece 21, a spreading mechanism 27 is provided. The spreading mechanism 27 includes a groove 30 on the rear cylinder 3, a sliding screw 31 rotatably mounted inside the groove 30, and a fixing plate 33 rotatably sleeved outside the sliding screw 31. The fixing plate 33 is fixedly connected to the groove 30. A rotating rod 32 is provided inside the groove 30. One end of the rotating rod 32 rotatably passes through the front cylinder 2 and is coaxially mounted with a handle 52. The rotating rod 32 and the sliding screw 31 are connected by a bevel gear set. It is worth mentioning that the bevel gear set includes a first bevel gear 34 and a second bevel gear 35 that mesh with each other. The first bevel gear 34 is coaxially mounted with the rotating rod 32, and the second bevel gear 35 is coaxially mounted with the sliding screw 31. One end of the sliding screw 31 is threadedly connected to a slider 29. One end of the slider 29 extends to the outside of the rear cylinder 3 and is fixedly connected to an arc-shaped scraper 28. The end of the arc-shaped scraper 28 away from the slider 29 is fixedly connected to a scraper blade 36 and a baffle 37.

[0037] Through the above technical features: the rotating handle 52 drives the rotating rod 32 to rotate, the rotating rod 32 drives the sliding screw 31 to rotate, the sliding screw 31 drives the slider 29 to move, and the slider 29 drives the arc-shaped scraper 28 to move until the appropriate position is reached. At this time, when the mounting plate 19 is closed, the scraper 36 on the arc-shaped scraper 28 scrapes the surface of the mounting plate 19, removing the uneven areas of the coating on the surface of the mounting plate 19. This allows for control of the coating thickness, ensuring uniform coating and controllable coating thickness, resulting in a better coating effect on the coating test piece 21.

[0038] To apply coating to the surface of the coating test piece 21, a fine-tuning mechanism 41 is provided. The fine-tuning mechanism 41 includes two transmission grooves 43 on the outer surface of the rear cylinder 3. A rotating screw 44 is rotatably mounted within the transmission grooves 43, and a coating plate 45 is threaded onto the external surface of the rotating screw 44. The coating plate 45 is slidably mounted against the inner wall of the transmission grooves 43. A rotating ring 42 is rotatably mounted outside the rear cylinder 3, and rotating gears 48 are coaxially mounted on the external surface of the rotating screw 44. Both rotating gears 48 are meshed with the rotating ring 42. A fine-tuning motor 49 is installed within the transmission grooves 43, and its drive shaft is coaxially mounted with the rotating screw 44. Coating rollers 46 are mounted outside the coating plates 45. A coating mechanism 50 for deflecting the two coating rollers 46 is provided outside the rear cylinder 3. Furthermore, the coating mechanism 50 includes a connecting ring 60 sleeved outside the rear cylinder 3, with both ends of the connecting ring 60 fixed to the two coating plates 45 respectively. The connecting ring 60 has two residual tooth rings 51 rotatably mounted on it. A U-shaped plate 53 is fixedly connected to the connecting ring 60. It should be noted that one end of the U-shaped plate 53 is connected to the connecting ring 60, while the other end is suspended and not connected to any component. Two external meshing wheels 55 are rotatably mounted inside the U-shaped plate 53. The two external meshing wheels 55 are respectively engaged with the two residual tooth rings 51. On opposite sides of the two external meshing wheels 55, internal meshing wheels 56 are coaxially mounted. The two internal meshing wheels 56 are engaged. An applicator motor 54 is mounted outside the U-shaped plate 53. The drive shaft of the applicator motor 54 rotatably passes through the U-shaped plate 53 and is coaxially mounted with the external meshing wheels 55. A connecting shaft 47 is rotatably mounted through the applicator plate 45. The connecting shaft 47 is fixedly connected to the coating roller 46. A meshing gear 61 is coaxially mounted on the other end of the connecting shaft 47. The two meshing gears 61 are respectively engaged with the two residual tooth rings 51.

[0039] Through the above technical features: after the paint detection piece 21 is unfolded, the drive shaft of the fine-tuning motor 49 drives two rotating screws 44 to rotate. The two rotating screws 44 drive two coating plates 45 to move. The coating plates 45 drive the connecting ring 60 and the coating roller 46 to move until the coating roller 46 comes into contact with the paint detection piece 21. At this time, the coating motor 54 drives two external meshing wheels 55 to rotate relative to each other. The external meshing wheels 55 drive two residual tooth rings 51 to rotate relative to each other. The two residual tooth rings 51 drive two connecting shafts 47 to rotate relative to each other through the meshing gear 61. The connecting shafts 47 drive the coating roller 46 to rotate. When the coating roller 46 rotates, it can coat the surface of the paint detection piece 21, thus automatically coating the surface of the paint detection piece 21. The coating process is relatively simple.

[0040] To simulate the effect of light at different distances and intensities on the heat insulation effect of the coating, a position adjustment mechanism 7 was set up. The position adjustment mechanism 7 includes multiple movable screws 8, which are fixedly connected to multiple spotlights 6 respectively. The movable screws 8 are slidably installed through the front cover plate 5. The external threads of the movable screws 8 are fitted with threaded sleeves 9. The threaded sleeves 9 are rotatably installed with the front cover plate 5. The multiple threaded sleeves 9 are connected to each other through a gear transmission mechanism. It should be noted that the gear transmission mechanism includes multiple transmission gears 11. The multiple transmission gears 11 are coaxially installed with the multiple threaded sleeves 9 respectively. A transmission gear ring 10 is rotatably installed on the outside of the front cover plate 5. The inner side of the transmission gear ring 10 is provided with annular tooth grooves that mesh with the multiple transmission gears 11. A position adjustment power motor 12 is installed on the outside of the front cover plate 5. A power gear 13 is coaxially installed on the drive shaft of the position adjustment power motor 12. The transmission gear ring 10 is provided with annular tooth grooves that mesh with the power gear 13.

[0041] Through the above technical features: the drive shaft of the position-adjusting motor 12 drives the drive gear 13 to rotate, the drive gear 13 drives the transmission gear ring 10 to rotate, the transmission gear ring 10 drives the threaded sleeve 9 to rotate through multiple transmission gears 11, the threaded sleeve 9 drives the moving screw 8 to move, and the moving screw 8 drives the spotlight 6 to move until the appropriate position is reached. At this time, the spotlights 6 located on both sides of the partition 58 simulate the same spectrum of illumination. When illuminating the two paint test pieces 21, a comparison is made. By rotating the position of the front cover 5, different spotlights 6 can be replaced. Different spotlights 6 simulate different lighting conditions for testing the reflective heat insulation performance of the paint, and the range of paint performance testing is relatively wide.

[0042] Working principle:

[0043] 1) Opening and closing of mounting plate 19: The drive shaft of the opening and closing motor 26 drives two reverse gears 25 to rotate relative to each other. The two reverse gears 25 drive the forward shaft 17 and the reverse shaft 18 to rotate in the opposite direction. The forward shaft 17 and the reverse shaft 18 drive the two mounting plates 19 to rotate relative to each other through two connecting plates 38. The mounting plates 19 drive the coating detection piece 21 to rotate, so that the mounting plates 19 can be opened and closed. When unfolded, rare earth reflective heat insulation and cooling coating is applied to the coating detection piece 21. After closing, the heat insulation effect of rare earth reflective heat insulation and cooling coating can be tested. The application of rare earth reflective heat insulation and cooling coating is relatively simple.

[0044] 2) Applying paint: After unfolding the paint detection piece 21, the drive shaft of the fine-tuning motor 49 drives two rotating screws 44 to rotate. The two rotating screws 44 drive two coating plates 45 to move. The coating plates 45 drive the connecting ring 60 and the coating roller 46 to move until the coating roller 46 comes into contact with the paint detection piece 21. At this time, the coating motor 54 drives two external meshing wheels 55 to rotate relative to each other. The external meshing wheels 55 drive two residual tooth rings 51 to rotate relative to each other. The two residual tooth rings 51 drive two connecting shafts 47 to rotate relative to each other through the meshing gear 61. The connecting shafts 47 drive the coating roller 46 to rotate. When the coating roller 46 rotates, it can apply paint to the surface of the paint detection piece 21. The paint application is relatively simple.

[0045] 3) Spreading the coating evenly: The rotating handle 52 drives the rotating rod 32 to rotate, the rotating rod 32 drives the sliding screw 31 to rotate, the sliding screw 31 drives the slider 29 to move, and the slider 29 drives the arc-shaped scraper 28 to move until the appropriate position is reached. At this time, when the mounting plate 19 is closed, the scraper 36 on the arc-shaped scraper 28 scrapes the surface of the mounting plate 19, removing the uneven areas of the coating on the surface of the mounting plate 19. This allows for control of the coating thickness, ensuring that the coating is applied evenly and the coating thickness is controllable. This results in a better coating effect on the coating test piece 21.

[0046] 4) Irradiation test of the coating: The drive shaft of the position adjustment motor 12 drives the drive gear 13 to rotate, the drive gear 13 drives the transmission gear ring 10 to rotate, the transmission gear ring 10 drives the threaded sleeve 9 to rotate through multiple transmission gears 11, the threaded sleeve 9 drives the moving screw 8 to move, and the moving screw 8 drives the spotlight 6 to move until the appropriate position is reached. At this time, the spotlights 6 located on both sides of the partition 58 simulate the same spectrum of irradiation. When irradiating the two coating test pieces 21, the results are compared. By rotating the position of the front cover 5, different spotlights 6 can be replaced. Different spotlights 6 simulate different light conditions to test the reflective heat insulation performance of the coating. After irradiation, multiple temperature sensors 59 record the temperature on both sides of the two coating test pieces 21, thereby comparing and judging the heat insulation performance of the coating.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
