[0002] Tobacco leaf grading refers to dividing tobacco leaves in the same group into different grades according to their quality. The grade division is based on the principle of consistency between appearance and interior, that is, the distinction is made on the basis of consistency between appearance characteristics and internal quality. The appearance factors used to measure the grade are called grading factors.

[0003] The utility model with the existing authorization announcement number CN218737178U discloses tobacco leaf grading equipment, including a lifting device, which is arranged under a conveyor belt; a first circular motion track and a second circular motion track, and a plurality of suction plates are arranged at intervals along the travel direction of the first circular motion track and the second circular motion track, the suction plates are located above the conveyor belt and the two ends of the suction plates are respectively arranged on the first circular motion track and the second circular motion track.
