[0050] Working principle;

[0051] Firstly, according to the required amount of aging materials, a corresponding number of placement plates 104 are taken out, then one group of placement plates 104 is placed in the inner cavity of the test box 100, and the two sides of the placement plate 104 are respectively attached to the inner cavity of the test box 100, then the hand-tightening bolts 505 are tightened in turn, the hand-tightening bolts 505 push the fixing blocks 500 outward, so as to abut against the inner cavity of the test box 100, thereby fixing the placement plate 104 and preventing the placement plate 104 from moving towards each other, then the remaining groups of placement plates 104 are installed in the inner cavity of the test box 100 in turn according to the above method;

[0052] At this time, the materials required for aging are placed on the top of the placement plate 104 and one side of the material is attached to the surface of the fixed plate 600, then the clamping plate 602 is taken out and placed on the top of the placement plate 104 and tightly attached to the other side of the material, at this time, the ends of the two groups of lead screws are turned along the surface of the fixed column 611, the other ends of the lead screws are respectively clamped in the inner cavities of the corresponding side accommodating grooves 605 of the clamping plate 602, and the nuts 702 are tightened in turn to push the clamping plate 602 inward, thereby clamping the material;

[0053] Then, the data parameters of the controller 300 are adjusted to control the humidity and temperature in the test box 100, then the electric heating pipe 402 and the fan 400 are started by the controller 300 to raise the temperature in the test box 100 to simulate a high-temperature environment, when it is needed to increase the humidity in the test box 100, the controller 300 controls the atomizer 201 to work to increase the humidity in the test box 100, thereby simulating a high-humidity environment;

[0054] When the hardness of the material needs to be detected, the controller 300 sends a signal to the electric push rod 706, and the electric push rod 706 performs the extension and retraction action according to the instruction, pushes the hardness sensor 701 to move along the circular hole 700 to the material, so that the probe of the hardness sensor 701 is in contact with the surface of the test material clamped between the fixed plate 600 and the clamping plate 602, and the hardness sensor 701 converts the detected hardness data into an electric signal and then transmits to the controller 300, so that the accurate measurement and real-time monitoring of the hardness of the material are realized.

[0055] Meanwhile, the color sensor 604 is fixed in the square hole 603 inner cavity, and when the test material is clamped between the fixed plate 600 and the clamping plate 602, the color sensor 604 is opposite to the surface of the test material, and can continuously perceive the color information of the material surface, and in the test process, once the color of the material changes, the color sensor 604 can timely capture the change, and convert the corresponding color change data into an electric signal, and then transmit to the controller 300, and the controller 300 analyzes the specific situation of the color change of the material by comparing the initial color data and the subsequent collected data, so that the effective monitoring of the color change of the material is realized.

[0056] The humidity sensor 302 monitors the air humidity at different positions in the test box 100 in real time, and transmits the humidity data to the controller 300 in the form of an electric signal; the temperature sensor 303 is placed on the top of the placement plate 104 through the magnetic suction disc 304, and can accurately measure the temperature of the environment where the material is located, and also feeds back the temperature data to the controller 300, and the hardness sensor 701 and the color sensor 604 respectively transmit the corresponding detection data to the controller 300 after completing the hardness detection and color monitoring, and the controller 300 receives the signals from various sensors, analyzes and judges according to the parameters set in advance, and transmits the obtained data to the display screen 301, so that the test personnel can intuitively understand the test progress and the change of the material performance.
