That is, the tobacco leaves need to be spread on the trays by hand and judged by hand whether the tobacco leaves meet the production requirements (whether the tobacco leaves are infested with insects, whether the tobacco leaves have leaf ear). The tobacco leaves that do not meet the production requirements are picked out by hand, and only the tobacco leaves that meet the production standards can be sent to the next process.

[0004] During the tobacco leaf sorting process, the staff engage in repetitive tasks, which can easily lead to visual fatigue and missed judgments, posing a risk of reducing the quality of the final tobacco leaf product. Utility Model Content

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Reference Figure 1 and Figure 2As shown in the embodiment of this application, a tobacco leaf screening device is disclosed, including: a screening platform 1; a rotating platform 2 rotatably mounted on the screening platform 1; a circular tray 3 detachably mounted on the rotating platform 2 for spreading tobacco leaves; a support 4 mounted on the screening platform 1 and spanning above the rotating platform 2; a lifting platform 5 vertically mounted on the support 4; a translation component 51 movably mounted on the lifting platform 5 along the radial direction of the tray 3; a clamping component 52 mounted on the translation component 51 for clamping tobacco leaves; an image detection component mounted on the support 4 on both sides of the translation component 51 for collecting image information of the tobacco leaves and determining whether they meet production requirements; a first driving component 61 for driving the rotating platform 2 to rotate; a second driving component 62 for driving the lifting platform 5 to move up and down; and a third driving component 63 for driving the translation component 51 to move linearly back and forth along the radial direction of the tray 3.

[0020] In practical use, firstly, the staff manually spread the tobacco leaves to be screened on the tray 3 and place the tray 3 on the rotating platform 2; randomly, the first drive component 61 is started intermittently, driving the rotating platform 2 to rotate, thereby driving the tray 3 to rotate, so that the tobacco leaves on the tray 3 are completely exposed under the image detection component; the image detection component collects the image information of the tobacco leaves and determines whether the tobacco leaves meet the production requirements.

[0021] When tobacco leaves that do not meet production requirements are found, the first drive unit 61 stops, the tray 3 remains stationary, the third drive unit 63 starts, and the moving part moves to above the tobacco leaves that do not meet production requirements. Then the second drive unit 62 starts, and the lifting platform 5 moves downward and clamps the tobacco leaves that do not meet production requirements through the clamping part 52. Then the second drive unit 62 starts, and the lifting platform 5 moves upward, and the third drive unit 63 moves the moving part away from the tray 3 until the clamping part 52 is moved above the outside of the tray 3. The clamping part 52 releases the tobacco leaves that do not meet production requirements. This cycle is repeated to complete the sorting of tobacco leaves in the circumferential direction.

[0022] By using this invention, the screening of tobacco leaves on tray 3 can be completed automatically, effectively reducing manual labor, minimizing missed screenings, and ensuring the quality of subsequent finished tobacco products.
