Magnetic steel II5 is fixedly installed at both ends of the placement rack base 6, and the two semicircular placement rack bases 6 are magnetically connected through the magnetic steel II5. The top placement rack 2 and the bottom placement rack base 6 are both connected by magnetic attraction, which is convenient for replacing and maintaining the placement rack 2 and the placement rack base 6.

[0030] A strip-shaped heating hole 26 is provided on the rotating disk 7. After the upper placement rack 2 and the lower placement rack base 6 are assembled, they are assembled together with the rotating disk 7 with the heating hole 26 through the mounting column 9. Hot air is blown out of the heating hole 26 to ensure that the surface of the sample has air at a certain temperature, which is convenient for the sample aging test.

[0031] like Figure 3 As shown, a locking piece 22 for clamping the fabric is provided on the sample clamp 16. The locking piece 22 is a locking nut. The sample clamp 16 is equipped with a clamping plate with a locking hole, which is not shown in the figure.

[0033] Working process: When it is necessary to test the color fastness of fabric to sunlight, first install the device in the detection area of ​​the detection box, and fix the connection between the motor shaft mounting hole and the motor shaft in the middle of the rotating disk 7, which can be screwed. Then install the sample fabric on the sample clamp 16, and then clamp the upper hook 21 of the sample clamp 16 on the placement rack 2, and move it downward for a distance through the action of the spring 24 in the fixed block 14, so that the lower hook 23 can hang on the placement rack base 6; the installation method of the remaining sample clamps 6 is the same. After the sample clamp is installed, close the experimental compartment door of the detection box and seal and cover the detection box. There is a heat blower under the rotating disk 7 to blow out hot air, and the hot air is sent out from the heating hole 26 to ensure that the surface of the sample has air at a certain temperature. Then, the motor and the xenon lamp are started, and the motor output drives the rotating disk 7 to rotate, and the rotation of the rotating disk 7 drives the placement rack 2 to rotate, and the sample fabric is irradiated by the xenon lamp to simulate sunlight to test the color fastness of the fabric, and test the color fastness of the fabric to sunlight. After the test is completed, the motor and the xenon lamp are turned off, the experimental chamber door is opened, the sample clamp 16 is taken out, and then the fabric after irradiation is removed from the sample clamp 16, and subsequent color comparison is performed to test the color fastness of the fabric to sunlight.
