Detailed Implementation

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Example 1

[0022] A yellowing resistance testing device for a slitting machine, such as Figures 1-3 As shown, the test chamber includes a test box 1 with two locking devices. A door 2 is rotatably connected to the front of the test box 1, and the door 2 has a handle. A rotating assembly 3 is mounted on the test box 1, including a drive assembly 31. The drive assembly 31 includes a drive motor and gears. The drive motor is mounted on the right side of the test box 1, and gears are connected to the output shaft of the drive motor. Gears are also rotatably connected to the right side inside the test box 1, and the two gears mesh. Rotating components 32 are rotatably connected to both the left and right sides inside the test box 1. 32 meshes with the adjacent gear. The upper and lower parts of the rotating part 32 are connected to 3 mounting plates 4. Each mounting plate 4 is provided with 5 simulation components 5. Each simulation component 5 includes a first mounting part 52. Each mounting plate 4 is connected to 10 first mounting parts 52. A simulation lamp 51 is connected between every 2 adjacent first mounting parts 52. Each mounting plate 4 is connected to 3 focusing parts 53. The focusing parts 53 correspond to the adjacent simulation lamps 51. The test box 1 is connected to a placement part 6. The placement part 6 is provided with a pressing mechanism 7.

[0023] like Figure 2 and Figure 4 As shown, the clamping mechanism 7 includes a second mounting member 71. The upper sides of the left and right parts of the placement member 6 are connected to the second mounting member 71. The second mounting member 71 is rotatably connected to the lower pressing member 72. The lower part of the lower pressing member 72 is provided with a rubber pad. The front and rear parts of the lower pressing member 72 are connected to the placement member 6 with torsion springs 73.

[0024] It should be noted that the slitting machine is a mechanical equipment for cutting wide web into multiple narrow webs, and the slitting machine needs to be tested for yellowing resistance during production to simulate the evaluation of the yellowing resistance of the slitting machine material under the environmental conditions of light, heat, oxygen, etc. Open the box door 2 on the front side of the test box 1, place the sample to be tested on the placing piece 6, and press the sample downward by the elastic force of the downward pressing piece 72 of the torsional spring 73. The rubber pad at the lower part of the downward pressing piece 72 ensures that the sample surface is uniformly stressed and avoids damaging the sample surface. After the sample is fixed, close the box door 2 and lock it with the locking piece. Then start the driving motor, and the output shaft of the driving motor drives the gear to rotate, thereby driving the other gear and the rotating piece 32 to rotate. The simulation lamp 51 emits ultraviolet rays or visible light to simulate different light conditions. The light focusing piece 53 focuses the light to enhance the light intensity and ensure that the sample surface is uniformly illuminated. The rotatable characteristics of the rotating piece 32 allow the light angle and intensity of the simulation lamp 51 to be dynamically adjusted to simulate the variable light environment in actual use. The fixed connection between the placing piece 6 and the test box 1 ensures that the placing piece 6 is not affected when the rotating piece 32 drives the simulation assembly 5 to move, thereby ensuring the stability of the test process.

[0025] Embodiment 2

[0026] Based on embodiment 1, as shown in Figure 1 、 Figure 2 and Figure 5 , it further includes a cold air mechanism 8, which includes a blower 81. The blower 81 is installed on the upper side of the test box 1, and a air outlet pipe 82 is connected between the blower 81 and the test box 1. A filter plate 83 is connected to the lower part of the air outlet pipe 82, and a temperature detector 84 is arranged at the upper part inside the test box 1.

[0027] It should be noted that in order to ensure that the test environment temperature meets the requirements, the temperature detector 84 can monitor the temperature inside the test box 1. If the temperature inside the test box 1 is too high, the cold air mechanism 8 is started, and the blower 81 sends cold air into the test box 1 through the air outlet pipe 82. The cold air is evenly distributed in the box after being filtered by the filter plate 83, reducing the temperature and keeping the air flowing.
