Background
China has been a large textile country, and cotton as one of textile raw materials is widely applied to the field of textile processing. Due to the decentralized and non-standardized cotton production status of China, foreign matters such as cotton seeds, branches and leaves fragments, broken shells, dead bodies and foreign fibers are often mixed in the cotton during picking, transportation and processing. Although the content of the impurities is very small, if the impurities are mixed in the subsequent spinning process of cotton, the normal operation of the spinning process is influenced, obvious dyeing and printing flaws are left in the subsequent dyeing process, and the production quality of products is further seriously influenced. Therefore, the impurities are removed as much as possible by means before the cotton processing, so that the quality of the subsequent processing of the cotton is ensured.
The existing detection methods which are commonly used comprise a photoelectric detection method, an ultrasonic detection method and a more accurate visual detection method, wherein the photoelectric detection method is to utilize a phototriode to identify and calculate the color difference between impurities and cotton, then generate a current difference in the phototriode, amplify a signal by the phototriode and compare the signal with a due standard value of raw cotton so as to analyze the existence of the impurities, but the method can not well detect colored fine impurities and colorless impurities; ultrasonic detection utilizes ultrasonic signal to launch and carry out the reflection on impurity, and impurity is different and then distinguish impurity with the reflected signal that the cotton produced, but ultrasonic transmission and reflection all need certain time, and when the transmission rate in the testing channel was too fast, ultrasonic detection just came too late discernment, and ultrasonic detection is also relatively poor to the detection effect of tiny impurity simultaneously.

When raw cotton passes through the photoelectric detection unit 21, the photoelectric detection unit 21 utilizes a phototriode to identify color difference between foreign matters and cotton and form a current signal in the phototriode, then the phototriode amplifies and uploads the current signal to the first computer 22, the first computer 22 analyzes image information and compares the image information with image information corresponding to pure raw cotton, after the position of impurities is confirmed, the distance between the detection position and the first high-pressure spray gun 24 and the conveying speed of the cotton conveying belt 6 are combined, then a control signal is output to the first controller 23, further the first high-pressure spray gun 24 is controlled to spray high-pressure air flow downwards, the high-pressure air flow sprays impurity parts and a small area containing the impurities and falls from a grid of the cotton conveying belt 6, and the primary impurity removal process is completed.
The raw cotton is further detected through the high-definition CCD camera 31 after being primarily purified, the detection process is that three groups of high-definition CCD cameras 31 form a detection area with a certain length along the length direction of the cotton conveying belt 6, for example, the coverage length is L, when the cotton conveying belt 6 conveys the raw cotton with the length of L to the detection area formed by the high-definition CCD cameras 31, each group of high-definition CCD cameras 31 corresponds to one part of the raw cotton with the length of L, when the raw cotton passes through one L length, the high-definition CCD cameras 31 only need to pass through one snapshot capturing process and then upload the raw cotton to the second computer 32, the raw cotton is processed and then transmits signals to the second controller 33, and then the second high-pressure spray gun 34 is controlled to spray high-pressure air flow downwards, and the high-pressure air flow sprays impurity parts and a small area containing impurities and falls from the grids of the cotton conveying belt 6.
The fallen impurities fall onto the comparison conveyer belt 13 below the cotton conveying conveyer belt 6 and are collected.
