The first sensor 13, the second sensor 14, and the third sensor 15 are all photoelectric switches.

[0029] Specifically, the frame 1 includes support plates 27 on both sides, and the support plates 27 on both sides are connected by support beams 28. Support feet are provided at the bottom of the support plates 27, and a second conveyor belt bracket 30 is provided at the top of the support beam 28. The second conveyor belt 5 and the third conveyor belt 7 are installed on the second conveyor belt bracket 30. A first conveyor belt bracket 29 is provided in the upper hopper 3, and the first conveyor belt 9 is installed on the first conveyor belt bracket 29.

[0030] The first conveyor belt 9 includes a plurality of first rollers 16 , which are rotatably mounted on a first conveyor belt support 29 via bearings. Two adjacent first rollers 16 are connected via a belt 17 , and one of the first rollers 16 is connected to the first motor 10 .

[0031] The second conveyor belt 5 includes a plurality of second rollers 18 , which are rotatably mounted on a second conveyor belt support 30 via bearings. Two adjacent second rollers 18 are connected via a belt 17 , and one of the second rollers 18 is connected to the second motor 6 .

[0032] The third conveyor belt 7 includes a plurality of third rollers 19, which are rotatably mounted on the second conveyor belt bracket 30 via bearings, and two adjacent third rollers 19 are connected via a belt 17, wherein one of the third rollers 19 is connected to the third motor 8, and an anti-skid layer 20 is provided on the outer sleeve of the third roller 19, and the anti-skid layer 20 is mainly used to increase the friction with the tobacco rods to ensure that the third conveyor belt 7 can effectively deliver the tobacco rods.

[0033] The frame 1 above the output end of the third conveyor belt 7 is provided with a second baffle 21, and the gap between the second baffle 21 and the third conveyor belt 7 is greater than the height of one layer of tobacco rods, and the gap between the second baffle 21 and the third conveyor belt 7 is less than the height of two layers of tobacco rods. That is, only the lowest layer of tobacco rods can pass between the second baffle 21 and the third conveyor belt 7.

[0034] A third baffle 22 and a third driving mechanism 23 for driving the third baffle 22 to move up and down are provided at the junction of the second conveyor belt 5 and the third conveyor belt 7, and the controller 2 is electrically connected to the third driving mechanism 23.

[0037] Working principle:

[0038] After the worker pours the whole box of cigarettes into the upper hopper 3, the controller 2 detects the presence of cigarettes through the first sensor 13, and detects that there is a vacant position on the second conveyor belt 5 through the second sensor 14, and then controls the upper hopper 3 to turn upward by 90°. Fig. 9 As shown, at this time, the first conveyor belt 9 is flush with the second conveyor belt 5, and the first conveyor belt 9 conveys the tobacco rods in the loading hopper 3 to the second conveyor belt 5. When the third sensor 15 detects that there are no tobacco rods on the third conveyor belt 7, the third baffle 22 rises, and the second conveyor belt 5 conveys a row of tobacco rods to the third conveyor belt 7, and the third baffle 22 descends. The controller 2 controls the designated first baffle 11 to descend according to the cigarette request instruction of the cigarette sorting line host, and the third conveyor belt 7 sends the bottom layer of tobacco rods to the cigarette sorting line. The third conveyor belt 7 stops, and the first baffle 11 rises to realize automatic loading, which can reduce the labor intensity of workers.

[0039] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the utility model, which will not affect the effect of the implementation of the utility model and the practicality of the patent.
