The lower cover deployment mechanism 2 works as follows:

when the cigarette reaches the station of the lower cover unfolding mechanism 2, the lifting motor 105 drives the spiral lifter 104 to rotate, so that the descending centering mechanism 108 on the lifting frame 103 descends until the triggering rod 1087 on the descending centering mechanism 108 contacts with the top of the smoke box, at the moment, the photoelectric detection switch 1086 is triggered, and a triggering signal is sent to the PLC control system, and the PLC control system starts to orderly control each mechanism to execute actions. At this time, the transmission line 1 and the lifting motor 105 stop working, so that the smoke box stays right below the lower cover spreading mechanism 2, then the long holding and clamping cylinder 1063 acts, so that the cover spreading devices 109 on the left side are closed to the cover spreading devices 109 on the right side until the smoke pressing plates 1100 on the cover spreading devices 109 on the two sides press the cover on the two sides of the smoke box from the two sides, then the sucking disc telescopic cylinder 1094 stretches out, and the cover sucking disc 1102 sucks the lower cover of the smoke box to pull out a gap of 5-10 mm.

At this time, the cutter-spreading cylinder 1093 is also extended, so that the tape between the lower cover and the smoke box is cut off when the two cutters 1101 are separated toward both sides, which completes the spreading action of the lower cover.

In addition, since the descent centering device 108 is connected to the gantry 101 through the link chain 1085, the lift frame 103 and the descent centering device 108 form a stroke-by-stroke relationship under the action of the sprocket a1089 and the sprocket B1090, that is: the distance the lifting frame 103 descends is exactly 2 times the distance the descent centering mechanism 108 descends.
