[0001] The utility model relates to the technical field of food processing, in particular to a visual screening device for vegetable products. Background Art

[0002] The processing of traditional pickled mustard greens is still mostly done in traditional family workshops. When carrying out industrial production of pickled mustard greens, it is inevitable to automate each process step. Among them, the screening of the color of the processed pickled mustard greens is relatively labor-intensive. It is necessary to screen out pickled mustard greens of appropriate size as needed, and also to screen out pickled mustard greens of good color.

[0003] The authorization announcement number is CN214812800U, which discloses a pickled mustard greens color screening device. Combined with its specification and drawings, its scheme is to use a conveyor belt to convey the pickled mustard greens to a photo identification device. After photo identification, the pickled mustard greens with unqualified color are identified, and the control system controls the air outlet at the corresponding position through a control valve to open and blow air, thereby changing the movement trajectory of the pickled mustard greens at that location and separating them from qualified pickled mustard greens. However, when this scheme is adopted, the pickled mustard greens blown away by the air outlet are actually still on the same guide glass as the qualified pickled mustard greens. This obviously has a chance of taking the qualified pickled mustard greens to other locations, causing inconvenience during production. Summary of the invention

[0022] Working principle and usage of this utility model:

[0023] First, put the pickled mustard greens on the surface of the conveyor belt 12, and then the external drive motor can drive at least one conveying drive shaft 13 to rotate. When the conveying drive shaft 13 rotates, it will drive the conveyor belt 12 to move. During the movement of the conveyor belt 12, the conveying drive shaft 13 on the other side plays a supporting and guiding role. The conveyor belt 12 will gradually transport the pickled mustard greens to the leftmost side and fall to the feed inlet 32. During the falling process, the visual sensor 22 will perform recognition and judgment to identify the color quality or the size of the pickled mustard greens. Whenever the pickled mustard greens are judged to be qualified, the blowing element 4 will not work. At this time, the pickled mustard greens will normally fall onto the surface of the guide surface 33 from the feed port 32, and slide to the first discharge port 34 under the guiding action of the guide surface 33. Whenever the pickled mustard greens are judged to be unqualified, before falling onto the guide surface 33, the blowing element 4 will work to generate an airflow to blow the unqualified pickled mustard greens, so that the pickled mustard greens will pass through the second discharge port 35 and fall onto the surface of the guide ramp 36, and slide to the designated position under the guiding action of the guide ramp 36. The movement trajectory of the pickled mustard greens will be changed by the blowing element 4, so that they will enter the first discharge port 34 or the second discharge port 35 respectively.
