When the integrity or color of the plastic particles meets the standards, the conveyor 1 and the dividing block 4 cooperate to convey the plastic particles to the second conveying pipe 22, and the second conveying pipe 22 conveys the plastic particles to the subsequent receiving location. When the plastic particles do not meet the standards, the dividing block 4 Rotating to the other side, the plastic particles move along the side of the dividing block 4 toward the first conveying pipe 21, and the first conveying pipe 21 conveys the material to the collection point, which is convenient for subsequent processing of the plastic particles. The plastic particles are separated by the dividing block 4, and the classification task can be completed quickly and accurately, reducing the complexity and error rate of manual operation and improving production efficiency. When the dividing block 4 rotates to perform the separation operation, the scraper 23 will scrape the inner wall of the corresponding first conveying pipe 21 or the second conveying pipe 22 to prevent the plastic particles from sticking to the inner wall of the first conveying pipe 21 and the second conveying pipe 22, and prevent blockage caused by the aggregation of plastic particles.
