AI Technical Summary
In the existing technology, the long-term stacking and storage of tobacco leaves in the frame leads to dense stacking during unloading, which causes the spreading mechanism to frequently come into hard contact with the tobacco leaves, resulting in breakage and damage. Furthermore, the spreading effect is poor, affecting production efficiency and equipment stability.
The structure combines a tilting support with a discharge rake. By slowly rotating and discharging layer by layer, the discharge rake gradually scrapes the tobacco leaves from inside the frame, avoiding accumulation and achieving uniform material discharge.
It reduces tobacco leaf breakage, improves production efficiency, reduces equipment energy consumption and wear, and ensures even spreading and production line stability.

The rake handle (211) is coaxially sleeved on the outer periphery of the first rotating shaft (212) and rotates together with the first rotating shaft (212); The two ends of the first rotating shaft (212) are rotatably connected to one end of the two rake arms (213), and the other ends of the two rake arms (213) are connected to the second rotating shaft (214); The two ends of the second rotating shaft (214) are rotatably mounted on the second bracket (22), forming a support and guide for the unloading rake (21), so that the unloading rake (21) can rotate around the second rotating shaft (214) under the driving action and gradually extend into the inside of the overturning bracket (11) to scrape off the tobacco leaves.
4. The tobacco leaf frame bar turnover and unloading device according to claim 3, characterized in that, The unloading rake (21) is connected to the second reduction motor mounted on the second bracket (22) via the second rotating shaft (214), and the output shaft of the second reduction motor is fixedly connected to the second rotating shaft (214); The second geared motor drives the unloading rake (21) to gradually extend into the interior of the overturning bracket (11) in a controlled and slow rotation around the second rotating shaft (214).
5. The tobacco leaf frame bar turnover and unloading apparatus of claim 4 wherein, One end of the first rotating shaft (212) is connected to the output shaft of a stepper motor mounted on the rake arm (213) via a coupling. The stepper motor is used to drive the first rotating shaft (212) to rotate at a preset speed, thereby driving the rake (211) mounted on the first rotating shaft (212) to rotate synchronously, so as to realize the continuous scraping action of the rake nails on the tobacco leaves.
6. The tobacco leaf frame bar turnover and unloading apparatus of claim 1 wherein, The flipping bracket (11) is a top-opening frame structure for supporting the tobacco frame, and its size matches the tobacco frame. The bottom and / or side wall of the flipping bracket (11) are provided with a clamping device for positioning and fixing the tobacco frame during the flipping process to prevent it from shaking or falling off. The flipping bracket (11) is also provided with a frame inlet and outlet (112) on one side so that the tobacco frame can be loaded into or removed from the flipping bracket (11).
7. The tobacco leaf frame bar turnover and unloading apparatus of claim 6 wherein, The clamping device is a mechanical buckle, pneumatic clamp or wedge-shaped pressure block structure set at the bottom or side of the flipping bracket (11) to clamp and fix the frame after it is installed, and to keep the frame stable and not slip during the flipping process of the flipping bracket (11).
8. The tobacco leaf frame bar turnover and unloading apparatus of claim 1 wherein, The device further includes a first position detection sensor, which is disposed on the first bracket (12) and located within the trajectory range of the rotating bracket (11) around the rotating connecting rod (111).
