1. and a manual identification picking method is adopted. The manual identification adopts a method of looking at the mark or burning to look at the smell of flame for similar plastics, has low treatment efficiency and is easy to make mistakes.
2. The near infrared NIR sorting method is adopted, near infrared light is irradiated on the plastic, reflected spectrums are collected and analyzed, a computer compares the original spectrums of the plastic, the plastic varieties are identified, and different kinds of plastic are blown out by air. The method has large processing capacity, 3 tons can be processed per hour, but the equipment cannot identify the black dark gray plastic which contains labels and is round and easy to roll. Moreover, the classification method has the disadvantages of very expensive equipment investment, high treatment cost and difficult popularization.
3. The electrostatic separation method is used for classification by utilizing different dielectric constants of plastics, is suitable for domestic and foreign large-scale enterprises, is mature, can separate two materials at a time, and is mainly suitable for classification of engineering plastics. The disadvantages are that strict feeding conditions exist, firstly, the materials are required to be in a flake shape, so that the treatment capacity is limited, secondly, the materials need to be dried firstly and contain no water, the treatment cost is high, and the popularization is difficult.
4. The AI image recognition method is used for photographing various shapes and angles of all common plastic articles for daily use, storing image data, defining plastics for classification, establishing a database, photographing and shooting one by one during feeding and sorting, acquiring data, then comparing the data with the database for recognition, and triggering a sorting mechanical structure. The method needs larger data calculation amount, is provided with a plurality of calculation servers, but only can process one material at a time, has high equipment investment, is not ideal in sorting efficiency, has higher processing cost and is difficult to popularize.
