[0032] Reference Figure 1-4 A cigarette replenishing device for cigarette storage and conveying equipment includes a cigarette drop bin 2, a stirring component 3, a cigarette tray 1 and a controller.

[0033] The cigarette drop bin 2 comprises a back plate 21, a V-shaped guide bottom plate 22 arranged perpendicular to the back plate 21, and a front baffle plate parallel to the back plate 21. The upper end opening of the cigarette drop bin 2 is a cigarette input port, and the bottom end of the guide bottom plate 22 is provided with a cigarette output port. The back plate 21 and the front baffle plate are both transparent plates to facilitate observation of the amount of cigarettes in the cigarette drop bin 2. The distance between the back plate 21 and the front baffle plate is suitable for the length of a single cigarette.

[0034] The stirring assembly 3 includes a stirring block 33 located in the cigarette drop bin 2, and a motor, an eccentric disk 32 and a connecting rod 31 located outside the cigarette drop bin 2. The stirring block 33 is in the shape of an inverted isosceles triangle, the middle of which is rotatably connected to the back plate 21, one end of the connecting rod 31 is transmission-connected to the eccentric disk 32, and the other end is transmission-connected to the top of the stirring block 33. The rotation center of the stirring block 33 and the connection point with the connecting rod 31 are both located on the midline of the stirring block 33. As a further implementation of this embodiment, the motor is transmission-connected to the center of the eccentric disk 32, and the connecting rod 31 is eccentrically connected to the eccentric disk 32. The motor drives the eccentric disk 32 to rotate and causes the bottom end of the stirring block 33 to reciprocate left and right through the connecting rod 31 to loosen the cigarettes, prevent the cigarettes in the cigarette drop bin 2 from being squeezed together and unable to fall, and avoid squeeze damage between the cigarettes. Among them, the speed of the motor should not be too fast to damage the quality of the cigarettes, nor too slow to affect the speed of the cigarettes falling. In actual applications, under the premise of ensuring overall stable operation, the cigarette storage and conveying equipment's cigarette input speed was finally selected to be 4600 cigarettes / min, the cigarette output speed was 4800 cigarettes / min, and the motor speed was 60R / min.

[0035] The cigarette tray 1 is a rectangular box with an opening on the front side, and the size of its output end is the same as that of the cigarette input port. When the cigarette drop bin 2 needs to be replenished with cigarettes, the cigarette tray 1 with cigarettes stacked therein is located above the cigarette drop bin 2, and its output end is connected to the cigarette input port.

[0036] The output end of the cigarette tray 1 is provided with a pull-out cigarette baffle 11, and the left and right side walls of the cigarette tray 1 are respectively provided with card slots, in which the cigarette baffle 11 is inserted.
