S1, power-up initializing, waste plastic is placed on conveying mechanism；
S2, infrared light scanning light source are scanned waste plastic；
S3, NIR light electric explorer detect scanning signal, and will test information and be sent to control mechanism；
S4, control mechanism are analyzed and processed detection information, judge whether the waste plastic passed through should exclude；If so, into
Enter S5, if it is not, then entering S6；
S5, high-pressure jet mechanism sprays compressed air, by waste plastic delivery to abandoned stope；
S6, high-pressure jet mechanism do not work, and waste plastic freely falling body falls into collecting region.
