S6: during the secondary folded packet 3 passing from the first folding station d to the second folding station e, the front inner packet short side 13 enters the spiral folding groove of the spiral folding plate 262, and the front inner packet short side 13 moves along the spiral folding groove and is folded from the horizontal state to the vertical state.

S7: during the movement of the inner wrap from the flaring station b to the second folding station e, the inner wrap large surface 15 is always in a vertical position and moves along the gap between the inner side circular arc plate 292 and the outer side circular arc plate 291. When the inner package enters the third folding station f from the second folding station e, the inner package large surface 15 only receives the action of the inner spiral pressing section 2921, the inner package large surface 15 moves along the inner spiral pressing section 2921, the inner package large surface 15 is pressed to the top of the die box 202, and finally, the inner package large surface 15 forms an included angle of 20-30 degrees with the horizontal direction.

S8: after the inner bag moves to the third folding station f, the control system stops the rotation of the wheel disc 201 and starts the lower shovel plate driving assembly 281; lower blade drive assembly 281 moves lower blade 282 vertically inwardly of inner wrap facets 14, folding the top portion of inner wrap facets 14 from a vertical position to a horizontal position (as shown in fig. 6), and then resetting lower blade 282; starting an upper clapping plate driving assembly 283, wherein the upper clapping plate driving assembly 283 drives the upper clapping plate 284 to swing, and the upper clapping plate 284 swings downwards to press the large inner wrapping surface 15 to be in a horizontal state; then, the lower shovel plate driving assembly 281 is started again, and the lower shovel plate driving assembly 281 drives the lower shovel plate 282 to press on the inner package large surface 15, so that the inner package large surface 15 is prevented from rebounding and opening.

S9: after the inner wrap travels from the third folding station f to the outfeed station g, the conveyor belt in the pack outfeed path 30 outflows the inner wrap from the magazine 202 and the outfeed folder folds the inner wrap left long side 16 and inner wrap right long side 17 during the conveying process to form a rigid cigarette inner wrap, as shown in fig. 7.

S10: after the inner package is transported out of the die box 202 through the cigarette package output channel 30, the die box 202 rotates to the idle station h, the idle station h is detected by the idle station detection assembly 31 at the outer side of the idle station h, and if the inner package exists in the idle station h, the control system stops the rotation of the wheel disc 201 and performs corresponding fault detection. If no packet is present in the empty station h, the control system will drive the wheel 201 to rotate, and enter the next packaging cycle.
