Device and method for detecting color uniformity of three-color polyester

The invention discloses a three-color polyester color uniformity detection device, and relates to the field of computer color photometers. The three-color polyester color uniformity detection device comprises a tester main body, the back surface of the tester main body is fixedly connected with a fixed seat, the upper surface of the tester main body is provided with an imported white board, and an extruder is arranged right above the imported white board. According to the color uniformity detection device for the three-color polyester, when the pressure borne by the surface of the three-color polyester needs to be changed for multiple groups of experimental tests, the pressure between the squeezer and the imported white board is changed through the pressure adjusting assembly, so that different detection and debugging effects are achieved, the detection result is more accurate, and the detection efficiency is improved. When the number of folded layers or the thickness of the sample is changed, the distance be
