[0002] In the production process of cigarettes, tobacco leaf redrying is an important link between primary curing and cigarette production, and the main purpose of tobacco leaf redrying is to adjust and control the moisture content of tobacco leaves, facilitate safe storage and aging, and meet the needs of cigarette production.

[0003] In the tobacco leaf redrying process, the tobacco leaves wrapped with burlap after primary curing need to be transferred to the redrying loading conveyor belt first, and then the tobacco leaves are laid flat on the redrying loading conveyor belt for transportation and manual picking of impurities. The existing work of taking out the tobacco leaves from the burlap and laying them flat on the loading conveyor belt is mostly done by manual labor, which has the disadvantages of high labor intensity and high dust. Some newly built or renovated projects use mechanical claws to put tobacco leaves in burlap onto the redrying loading conveyor belt. This method is prone to damage to the tobacco leaves during the grabbing process, and the dispersion effect of the tobacco leaves is poor, such as laying the tobacco leaves in a bundle on the redrying loading conveyor belt, which affects subsequent production. For example, the disclosed patent tobacco leaf redrying loading process tobacco leaf clamp jaw (publication number CN211960886U) includes a U-shaped frame, a rotating shaft, a support piece, a clamping cylinder, a pressing piece, a connecting frame, and a pitch cylinder. The support piece is fixedly connected to the first edge of the opening end of the U-shaped frame. The cylinder body A of the clamping cylinder is fixedly installed at the second edge of the opening end of the U-shaped frame, and the piston rod A extends out of the first edge of the opening end of the U-shaped frame. The pressing piece moves closer to or further away from the support piece as the piston rod A of the clamping cylinder extends or retracts. The connecting frame is movably sleeved on the rotating shaft through the sleeve portion. The cylinder body B of the pitch cylinder is hinged to the connecting frame, and the piston rod B is hinged to the U-shaped frame. The piston rod B extends or retracts to drive the U-shaped frame to rotate around the rotating shaft. SUMMARY
