[0054] Further, a wrapper leaf inlet 30 is provided on one side of the first baffle 6 close to the conveying assembly 4, and a wrapper leaf outlet 31 is provided on one side of the second baffle 7 close to the conveying assembly 4. It can achieve a good effect of the wrapper leaves entering and exiting, thereby realizing the effect of improving the detection rate.

[0055] Further, as Figure 16-18 shown, both the first sorting device 35 and the second sorting device 36 include: a frame 38, a belt conveyor 39 is provided on the top of the frame 38, one end of the bottom of the belt conveyor 39 is hinged to the frame 38, and the other end is connected to the frame 38 through an adjustable support block 40.

At the same time, the silent fans 44 used have advantages such as low cost, low noise, and low energy consumption compared with others, such as high-pressure blowers.

[0057] Further, a blanking box lifting structure 48 is arranged inside the machine frame 38. The blanking box lifting mechanism includes: a mounting bottom plate 49, on which a motor mounting bracket 50 is arranged. On one side of the motor mounting bracket 50, a speed-regulating motor 51 is arranged. The speed-regulating motor 51 is connected to a worm and screw lift 53 through a coupling 52. At the top of the worm and screw lift 53, a support plate 54 is arranged. On the top of the support plate 54, a guiding chute 55 is arranged. On the guiding chute 55, a tobacco leaf collecting tray 56 is arranged. The tobacco leaf collecting tray 56 is located directly below the end of the belt conveyor 39. It can achieve the effects of blanking and storing materials, and at the same time, it can also achieve the effect of convenient material taking, so as to achieve the effect of flexible use, and further be able to adapt to a variety of practical environments. Furthermore, a height sensor is arranged inside the tobacco leaf collecting tray 56. The height sensor is electrically connected to the electric control box 37, and the electric control box 37 is electrically connected to the speed-regulating motor 51. It can achieve the effect of automatically detecting the storage amount of eggplant leaves, thus preventing the situation of eggplant leaf overflow. Specifically, the eggplant wrapper slides into the blanking box along the guiding mechanism. When a certain height is accumulated, the subsequent tobacco leaves are blocked from entering the box, and it also affects the alignment of the stacked tobacco leaves. When the position sensor detects the high-level tobacco leaves, the motor drives the worm and gear lift to descend, so as to create a space for the tobacco leaves to slide, forming a "U-shaped" blanking combination with adjustable depth with the guard plates on both sides of the storage box. After the tobacco leaves are stacked to a certain height, in order to facilitate the removal of the storage box, the lifting support plate 54 is designed as a guiding chute 55, which is convenient for the storage box to be smoothly pulled out, and at the same time, it is also convenient for the operator to quickly replace a new storage box to avoid interrupting the continuity of the equipment sorting.

[0058] Further, an automatic flipping and feeding mechanism 57 is provided on one side of the rack 38. The automatic flipping and feeding mechanism 57 includes: a cylinder mounting plate 58 fixedly connected to the bracket. A cylinder 59 is provided on the cylinder mounting plate 58. A connecting rod 60 is provided at the output end of the cylinder 59. A transmission rod 61 is provided on the connecting rod 60. Flipping support plates 62 fixedly connected to the bracket are respectively provided at both ends of the transmission rod 61. A flap 63 is provided on the transmission rod 61. A guide plate 64 is provided on the flap 63. The guide plate 64 is located above the tobacco leaf collection tray 56. Good flipping and feeding effects can be achieved, so as to achieve good grading and sorting effects. Further still, an auxiliary upper guide plate 65 is provided at the end of the belt conveyor 39. The auxiliary upper guide plate 65 is arranged opposite to the guide plate 64. Good auxiliary guiding effects can be achieved, so as to convey the eggplant leaves to the storage box. Specifically, the automatic flipping and feeding mechanism 57 functions as an opening / closing and a gate. This mechanism has two working stations. When the cylinder extends and retracts, it corresponds to the separation and fitting of the flipping guide plate 64 and the front-end conveyor. That is, when the cylinder extends, the flipping guide plate 64 separates from the front end, and the tobacco leaves flow out from the inner side of the guide plate 64. Similarly, when the cylinder retracts, the flipping guide plate 64 fits with the front end, and the tobacco leaves slide down along the outer side of the guide plate 64 to the next-level conveyor. Among them, the sliding of the tobacco leaves is through the auxiliary upper guide plate 64, which can reduce the floating phenomenon of light-quality tobacco leaves, and further reduce the misalignment degree of tobacco leaves during stacking.

[0059] Further, the number of the first sorting devices 35 and the second sorting devices 36 can be multiple. The multiple first sorting devices 35 and the second sorting devices 36 are sequentially arranged in stages. The effect of flexible adjustment according to the actual usage situation can be achieved, so as to increase or decrease the number of grading and sorting, and further achieve the effect of multi-stage sorting.

[0060] The working process of the present invention is as follows:

[0061] 1. Place the eggplant wrapper at the feeding port of the double-station dynamic image acquisition device. After the image of the eggplant wrapper is collected and processed, the current quality grade of the eggplant wrapper is determined, and the eggplant wrapper is output backward.

[0062] 2. When the eggplant wrapper enters the belt conveyor, if the grade of this piece of tobacco leaf is determined to be grade A, the corresponding actuator of the first stage starts to act.

[0063] 3. The cylinder drives the flipping mechanism to rotate, so that a gap appears between the first-stage and second-stage belts. At the same time, the air shower combination is started, and gentle wind blows out from the combination, forming a wind belt perpendicular to the conveying direction at the end of the conveyor.

[0064] 4. After the tobacco leaves reach the end of the first-stage conveyor, they fall downward into the receiving box through the guidance of the flipping mechanism.

[0065] 5. As the height at which the tobacco leaves fall increases, after height detection, the motor drives the screw rod to move downward, controlling the height of the tobacco leaves in the receiving box to be the same as the initial state;

[0066] 6. If the tobacco leaves are determined to be of Grade B, the primary conveying system and related supporting combinations do not operate, and the tobacco leaves naturally slide from the end of the primary belt conveyor to the secondary conveyor via the slide plate of the flipping mechanism;

[0067] 7. Similarly, for the treatment methods of other graded tobacco leaves, refer to the operations of the primary and secondary levels.
