Description

Technical Field

[0001] The utility model relates to the technical field of cotton inspection, in particular to special equipment for cotton inspection and testing. Background Art

[0002] At present, the quality of cotton depends on the maturity of cotton fiber. The maturity of cotton fiber refers to the degree of thickening of the fiber cell wall. The thicker the cell wall, the higher its maturity, the more fiber twists, the higher the strength, the stronger the elasticity, the better the color, and the relatively high yarn quality. Fibers with low maturity have poor economic properties, but over-mature fibers are not ideal either. The fibers are too thick, have few twists, and the yarn strength is not high. The maturity of cotton fibers is generally measured by a cotton maturity analyzer.

[0003] A special cotton inspection and testing device disclosed in the Chinese utility model patent application disclosure CN 211785538 U, the device is designed with a first fixed plate and a second fixed plate, and the hand wheel drives the screw rod to be screwed and connected with the slide plate, driving the two slide plates to move closer or farther from each other, so as to adjust the distance between the first fixed plate and the second fixed plate, and then control the installation height of the analyzer, so that it is suitable for operation by workers of different heights. However, the device can only adjust the height and measure the weight of cotton. When testing cotton, it is necessary to detect the temperature, humidity and length of cotton to analyze the quality of the cotton. Utility Model Content
