Description

Technical Field

[0001] The present invention belongs to the technical field of bio-based material testing equipment, specifically a photo-oxidative aging simulation testing device for bio-based materials. Background Art

[0002] A photo-oxidative aging simulation testing device for bio-based materials is a device used to test and study the aging performance of bio-based materials under light and oxidative environments. Photo-oxidative aging simulation testing is mainly used to evaluate the durability, aging rate, and performance changes of materials under ultraviolet light (UV), oxygen, and environmental conditions. Such devices generally use artificial accelerated aging methods to simulate the long-term effects of the natural environment in order to quickly evaluate the service life and performance degradation of materials.

[0003] For example, the utility model with the publication number CN210572541U discloses an aging testing device for optical modules, including a machine body, an aging board, and an operation panel. The bottom of the machine body is provided with universal wheels. One side of the machine body is connected with a machine door through a hinge. A glass window is provided on the machine door. An electrical cabinet is provided on one side of the machine door. A display screen is provided on the electrical cabinet. The operation panel is provided below the display screen. A test hole is provided below the operation panel. By setting the aging board, the aging board handle, and the bottom board, it is convenient for employees to pick up and will not accidentally touch the electronic components on the aging board. At the same time, it provides support for the aging board during testing to ensure the service life of the aging board. By setting the fan, the heat dissipation hole, and the slide plate, the device can be cooled after the optical module test is completed, improving the test efficiency of the optical module.

[0004] When the above device is testing, since the positions of the indicator lights and the positions for placing materials are fixed, during detection, the light sources at fixed positions may cause inconsistent light intensity and time for different regions of the sample. For example, the region close to the light source may be over-aged due to long-term high radiation intensity, while the region far from the light source may be under-aged, unable to accurately simulate the uniform aging process of the material in actual use. The test results may overestimate or underestimate the overall durability of the material. When the material is fixed in place, the relative angle between its surface and the light source is fixed, unable to simulate the different aging behaviors caused by angle changes in actual use of the material, and unable to comprehensively evaluate the performance changes of the material in different usage scenarios, restricting the universality of the test results.

[0005] Therefore, a photo-oxidative aging simulation testing device for bio-based materials is proposed to solve the problems raised in the background art. Summary of the Invention

[0006] To solve the problems raised in the above background art, the present invention provides a photo-oxidative aging simulation testing device for bio-based materials.

[0020] Preferably, a second fixing piece is threadedly sleeved on the outer wall of the lead screw. The second fixing piece is located between the knob and the first fixing piece.

[0024] The present invention has a significant multi-dimensional adjustment function by setting the rotation component, which can ensure that the bio-based material is at the best light test angle during the test. By combining the longitudinal and transverse rotation mechanisms, the bio-based material can be rotated omnidirectionally within the test area, thereby realizing precise adjustment of the light angle, which is crucial for ensuring the accuracy of the light test. Especially in the evaluation of the surface characteristics or light reflection characteristics of the material, multi-angle tests can provide more comprehensive and detailed data support, effectively improving the accuracy of the bio-based material test.

[0025] The present invention provides a convenient way to fix bio-based materials by setting the design of a clamping assembly, ensuring that the material will not be displaced or deformed during the test process. The clamping assembly can be accurately adjusted according to the size of the bio-based material to ensure that at least two groups of clamping assemblies are in contact with the edge of the material, thereby providing a stable supporting force. The fixing plate three and the fixing plate two cooperate with each other through the spring and the card block, making the fixing process simpler and more stable. The operator can complete the fixing and releasing of the fixing through a simple toggling action, avoiding the tedious manual operation. The design of the clamping assembly ensures the safe fixation of the bio-based material, can effectively prevent errors caused by looseness or vibration during the material testing process, ensure the accuracy and consistency of the test data, and enable the bio-based material to always maintain a stable position during the test process, which helps to obtain more accurate and reliable test results.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figures 1 to 10 shown, the present invention provides a bio-based material photo-oxidative aging simulation test device, including;

[0039] A box body 1, with a door body provided on the front surface of the box body 1;

[0040] A controller 101, fixedly installed on the top of the box body 1, for controlling test parameters;

[0041] A testing section 102, fixedly installed on the inner wall of the top of the box body 1, with functions of light, temperature, humidity, and oxygen concentration settings, for testing and evaluating the performance degradation law and life expectancy of materials;

[0042] A rectangular box 2, fixedly installed on the inner wall of the bottom of the box body 1, with a rectangular shape;

[0043] A rotating mechanism is arranged inside the rectangular box 2 for multi-dimensional testing of materials;

[0044] Among them, the rotating mechanism includes a rotating component and a clamping component. The clamping component is used to stably clamp the material. The rotating component is fixedly connected to the clamping component and is used to rotate and adjust the clamping component. The rotating component includes a driving group and a transmission group. The driving group provides the driving force for the transmission group. The driving group includes a motor 3 fixedly installed on the inner wall of the rectangular box 2. A first worm 301 is fixedly installed on the output shaft of the motor 3. A semi-gear 302 is fixedly sleeved on the outer wall of the first worm 301. Half of the semi-gear 302 is designed in a gear shape and the outer wall of the other half is smooth. A first rotating rod 4 is rotatably installed inside the rectangular box 2. The first rotating rod 4 is located above the motor 3. A second worm 401 is fixedly installed at one end of the first rotating rod 4. A gear 402 is fixedly sleeved at one end of the second worm 401. The gear 402 meshes with the semi-gear 302. The transmission group includes a Y-shaped block 5 rotatably installed inside the rectangular box 2. The top of the Y-shaped block 5 extends outside the rectangular box 2. A first worm gear 501 is fixedly sleeved at the bottom end of the Y-shaped block 5. The first worm gear 501 meshes with the second worm 401. A second rotating rod 6 is rotatably installed inside the Y-shaped block 5. The second rotating rod 6 penetrates the Y-shaped block 5. A second worm gear 601 is fixedly sleeved on the outer wall of the bottom end of the second rotating rod 6. The second worm gear 601 meshes with the first worm 301. A second bevel gear 602 is fixedly sleeved on the outer wall of the top end of the second rotating rod 6. A round rod 502 is rotatably installed on the inner wall of the top of the Y-shaped block 5. A first bevel gear 5021 and a mounting bracket 7 are fixedly sleeved on the outer wall of the round rod 502. The first bevel gear 5021 is located in the middle of the mounting bracket 7 and meshes with the second bevel gear 602.

[0045] Adopting the above solution: precise rotation adjustment is achieved through the setting of the rotating mechanism, enabling the clamping component to perform multi-dimensional rotation on the test material in a controlled manner, thereby simulating the aging process of the material in different directions and at different angles. This rotational movement can not only simulate the different external environmental conditions that the material may encounter in daily use, but also accelerate the aging effect of the material in multiple environments, making the experimental results more representative.

[0046] Through the above design, the device can highly simulate various complex environmental conditions that the bio-based material may encounter during actual use, provide accurate and scientific aging test data. With the help of these data, the material designers can better understand the degradation law of the material properties, optimize the material formula and structure, extend the service life of the material, and provide a reliable basis for the development of new environmentally friendly materials.

[0047] Such as Figures 7 to 10As shown, there are four groups of clamping components. The clamping component includes a moving groove 701 opened on the outer wall of the mounting bracket 7. A cylinder 8 is slidably installed on the inner wall of the moving groove 701. A lead screw 801 is fixedly installed at the top of the cylinder 8. A first fixing piece 8011 is rotatably sleeved on the outer wall of the lead screw 801. A knob 802 is fixedly sleeved on the outer wall of the other end of the cylinder 8. The first fixing piece 8011 is fixedly connected to the cylinder 8. By rotating the knob 802, the lead screw 801 is driven to rotate to provide power for the clamping component. A second fixing piece 9 is threadedly sleeved on the outer wall of the lead screw 801. The second fixing piece 9 is located between the knob 802 and the first fixing piece 8011. By rotating the lead screw 801, the second fixing piece 9 is driven to move along the axis of the lead screw 801 to change the distance between the second fixing piece 9 and the first fixing piece 8011 to adapt to materials of different thicknesses. A third fixing piece 10 is rotatably installed inside the second fixing piece 9. A positioning groove 901 is opened on the inner wall of the second fixing piece 9. The positioning groove 901 is designed in an L shape to limit the third fixing piece 10. An installation groove 1001 is opened on one side of the third fixing piece 10. A spring 1003 is fixedly installed in the installation groove 1001. The other end of the spring 1003 is fixedly installed with a clamping block 1002. The clamping block 1002 is clamped with the positioning groove 901. Anti-slip strips are arranged on both sides of the second fixing piece 9 and the third fixing piece 10 close to each other to prevent the sliding of the material during the clamping process.

[0048] Adopting the above solution: By rotating the knob 802, the lead screw 801 is driven to rotate, thereby adjusting the distance between the second fixing piece 9 and the first fixing piece 8011. This design enables the clamping component to adapt to materials of different thicknesses. Regardless of how the thickness of the material changes, the precise adjustment function provided by the lead screw 801 ensures the flexibility and reliability of the clamping component. The adjustment of the distance between the second fixing piece 9 and the first fixing piece 8011 not only improves the adaptability of clamping the material but also avoids clamping failure or material damage caused by over-tight or over-loose clamping. An L-shaped structure is designed in the positioning groove 901 in the second fixing piece 9, and the clamping block 1002 is used to limit the third fixing piece 10. The clamping of the clamping block 1002 with the positioning groove 901 ensures the precise positioning of the third fixing piece 10 during the clamping process, avoiding loosening or instability during the clamping process, and effectively avoiding the situation of insecure clamping caused by the clamping block 1002 not fully engaging with the positioning groove 901. The positioning groove 901 and the clamping block 1002 improve the clamping stability;

[0049] A number of anti-slip strips are arranged on the sides of the second fixing piece 9 and the third fixing piece 10 close to each other, further enhancing the stability of the material during the clamping process. The design of the anti-slip strips effectively prevents the sliding phenomenon caused by the smooth surface or uneven force of the material during the clamping process, avoiding the influence on subsequent operations due to the sliding of the material. Moreover, the anti-slip strips not only effectively improve the clamping force during clamping but also provide consistent stable performance during multiple uses, ensuring the consistency of the clamping quality;

[0050] In the above actual operation, whether it is adjusting the spacing between the fixing plates to adapt to materials of different thicknesses, or ensuring the stability of the fixing plate 10 through the cooperation of the block 1002 and the positioning groove 901, the design of the clamping assembly can provide precise clamping force in complex environments. The design of the clamping assembly simplifies the operation process. The user only needs to rotate the knob 802 to complete the clamping adjustment. There is no need for complicated operating steps, which improves the overall service life and ease of operation of the equipment.

[0051] The working principle and use process of the present invention:

[0052] First, the door of the box 1 is opened, and the bio-based material to be tested is taken out. The position of the cylinder 8 in the clamping assembly is adjusted according to the size of the bio-based material. The operator slides the cylinder 8 in the movable groove 701 so that the fixing piece 2 9 and the fixing piece 3 10 on the cylinder 8 can contact the edge of the bio-based material, ensuring that at least two of the four clamping assemblies are in contact with the bio-based material.

[0053] After adjusting the position of the cylinder 8, the fixing piece 3 10 is moved so that the fixing piece 3 10 forms a right angle with the fixing piece 2 9. During the moving process, the rotation action will squeeze the spring 1003, so that the clamping block 1002 leaves one side of the positioning groove 901. When the fixing piece 3 10 rotates to form a ninety-degree angle with the fixing piece 2 9, the spring 1003 rebounds and drives the clamping block 1002 to be clamped into the other side of the positioning groove 901. At this time, the operator can place the bio-based material on the top of the fixing piece 1 8011, and then rotate the fixing piece 3 10 in the opposite direction so that the fixing piece 3 10 is reset to a state consistent with the direction of the fixing piece 2 9, so that the bio-based material can be fixed between the fixing piece 1 8011 and the fixing piece 3 10 to fix it;

[0054] After the bio-based material is fixed, the door of the box 1 is closed, and the detection device in the test part 102 is started through the controller 101. At the same time, the motor 3 can also be started through the controller 101. The output shaft of the motor 3 rotates to drive the worm 1 301 and the half gear 302 to rotate. The worm 1 301 is meshed with the worm gear 2 601, thereby driving the worm gear 2 601 and the rotating rod 2 6 to rotate. The rotating rod 2 6 drives the bevel gear 2 602 to rotate. The rotation of the bevel gear 2 602 and the bevel gear 1 5021 drives the bevel gear 1 5021 and the round rod 502 to rotate. The mounting frame 7 and the bio-based material on the top of the mounting frame 7 are driven to rotate longitudinally through the round rod 502.

[0055] Meanwhile, since the gear part of the half gear 302 meshes with the gear 402, when the half gear 302 rotates to mesh with the gear 402, it will drive the gear 402 and the second worm 401 to rotate. Through the meshing of the second worm 401 and the first worm wheel 501, the Y-shaped block 5 is driven to rotate. The rotation of the Y-shaped block 5 can drive the mounting bracket 7 and the biobased material on the top of the mounting bracket 7 to rotate horizontally, enabling the biobased material to be adjusted in multiple dimensions and form different light testing angles with the light source in the testing part 102, making the test results accurate.
