The other end of the horizontal push rod 8 is fixedly connected to the vertical rotating shaft. The lower end of the vertical rotating shaft is rotatably connected to the horizontal plate 1 2 through a bearing. The lower end of the vertical rotating shaft passes through the horizontal plate 1 2 and is connected to the stepping motor 6.
[0021] The second horizontal plate 10 is provided with a plurality of synchronized horizontal push rods 8, which are evenly spaced along the length of the second horizontal plate 10. The vertical shaft connected to one of the horizontal push rods 8 is connected to the stepper motor 6, and the vertical shafts connected to two adjacent horizontal push rods 8 are connected by a transmission system of cooperating sprockets and chains 7. This arrangement improves the stability of the movement of the material retaining plate.
[0022] A support plate 5 is provided on the side wall of the frame 1. A vertical telescopic rod 4 is connected to the support plate 5. The fixed end of the vertical telescopic rod 4 is fixed to the frame 1. The telescopic end of the vertical telescopic rod 4 is vertically upward and fixedly connected to the lower surface of the support plate 5. The stepper motor 6 is fixed to the support plate 5. The lower end of the vertical rotating shaft is rotatably connected to the upper surface of the support plate 5 via a bearing.

[0025] Working Principle: Tobacco leaves are laid on a conveyor belt between two baffles and transported by the conveyor belt. The distance between the two vertical baffles is adjusted as needed to adjust the width of the tobacco leaves laid. Specifically, the vertical telescopic rod is extended, causing the baffle to move up and out of contact with the conveyor belt and frame. The stepper motor then rotates, driving the vertical shafts on the same side of the conveyor belt to rotate synchronously under the action of the sprocket and chain. Each horizontal push rod rotates synchronously with the corresponding vertical shaft as the center of the circle, driving horizontal plate 2 to extend from or retract into the accommodating cavity of horizontal plate 1. The length of the accommodating cavity is greater than that of horizontal plate 2, allowing horizontal plate 2 to move horizontally within the accommodating cavity to the maximum extent possible under the drive of the horizontal push rod. After the width between the two baffles is adjusted, the vertical telescopic rod is retracted, and the horizontal plate falls onto the frame. The width between the two baffles is thus adjusted.
