Online intelligent detection and control method for cotton processing quality

The invention discloses a cotton processing quality online intelligent detection and control method, and relates to the technical field of cotton processing, and the method comprises the following specific operation steps: S1, after a cotton processing system is started, feeding cotton into an automatic cotton feeding module for pretreatment; s2, under the action of a conveying belt, the pretreated cotton is conveyed into a cotton cleaning module, and seed cotton and impurities are separated; according to the technical key points, the density requirement for impurity separation is met by increasing the cotton feeding amount and increasing the number of seed cotton, the seed cotton can be effectively separated from impurities in the mode of reducing the cotton feeding amount, idling of a motor can be avoided while the cotton feeding amount is increased, and therefore the production cost is reduced; a two-dimensional code inkjet printer is additionally arranged in a cotton processing system, sampling detection
