The invention discloses a non-defective plastic mold material monitoring and feedback system, and relates to a product monitoring and feedback technology. The system comprises a shooting unit, a compensation unit, an identification unit and a feedback unit, wherein the shooting unit is used for acquiring image information of a plastic mold material, the compensation unit is used for randomly compensating the image information and generating an identification image, the identification unit is used for identifying the identification image and obtaining an identification result, and the feedback unit is used for transmitting the identification result, receiving a feedback mark and marking the feedback mark on the plastic mold material corresponding to the identification result. According to the invention, the plastic mold material can be quickly classified and marked through a preset instruction, secondly, by arranging industrial cameras with different shooting angles, even if a certain camera goes wrong or shooting is not clear under the condition of high-speed shooting, remedy can be carried out through the method, so that the photographing speed of the industrial camera and the screening speed of a color sorter are greatly improved.
