Specifically, the feeding control system comprises a color identification module, a feeding control module and a memory, wherein the color identification module is used for comparing the color of a plastic product picture shot by the high-definition camera 4 in real time with a pre-stored standard color picture and judging whether the colors are consistent. And the feeding control module is used for controlling the servo motor 241 and receiving the measuring data of the weighing platform 7, so that the accurate control of the feeding amount of the color master batches is realized. When the color identification module judges that the colors are consistent, the feeding is stopped, the usage amount of the plastic (weighed before being put into the mixing box 1) and the corresponding color master batch putting amount are recorded, and color matching data are generated and directly called when the secondary products produce the same-color products. And the memory is used for storing standard color pictures of various colors and color matching data for the color identification module and the feeding control module to call. It should be noted that since color concentrates of different colors are not as energy efficient as neutralized with plastic, it is not possible to formulate a single color formulation to determine the amount of other colors to be dosed.
In this embodiment, the feeding control module further has a manual feeding function and a voice feeding function, wherein the manual feeding function controls the servo motor 241 to rotate for feeding through comparing the plastic images and the color images to be blended by the staff. The voice feeding is realized by controlling a feeding control module based on a voiceprint recognition module and then controlling a servo motor 241.
The functions of the above modules are realized based on the PC system and the corresponding executed programs, which are not described herein again.
