When caching the second group of cigarettes, the second mounting frame 4 continues to drive the push rod 11 to move downward by the thickness of one group of cigarettes, reducing the impact force of the cigarettes falling when entering the fourth group of limit frames 10, and realizing effective protection of the cigarettes during the caching process.

The height of the whole roller 6 is adjusted so that the top surface of the cigarette strip fits with the adjustment roller 6. The adjustment roller 6 is made of rubber and has a large friction. Therefore, the cigarette strip transported on the conveyor belt 2 is given a certain resistance when passing through the adjustment roller 6 which has a certain friction and fits with the upper surface of the cigarette strip, so that the inclined cigarette strip can be adjusted to a horizontal state. At the same time, when the cigarette strip passes through the adjustment roller 6, the motor in the movable frame 5 is started to drive the bidirectional screw rod 9 to rotate, so that the two sets of limit rings 8 slide inward synchronously, thereby adjusting the position of the cigarette strip until the cigarette strip is located at the center of the conveyor belt 2.
