When the cigarette paper machine works, cigarette paper is driven by the cloth belt to move forwards, and the tobacco shreds are adsorbed by the shred adsorption belt in the wing plate, the cloth belt and the cigarette paper run synchronously. Under the drive of the cloth belt, the cigarette paper receives the cut tobacco which comes from the wing plate and is shoveled by the shovel blade, and the cut tobacco enters the rolling forming channel.

More specifically, after the tobacco shreds enter the cigarette tongue, the inner diameter of a channel formed by the cigarette tongue and the inlet cone of the cigarette gun becomes smaller and smaller, the density of the channel becomes larger and larger, and when the tobacco shreds reach the outlet position of the cigarette tongue, the diameter of the tobacco shreds is smaller than that of the cigarettes. The cloth belt and the cigarette paper are between the cigarette tongue and the cigarette gun inlet cone and in the same line with the tobacco shreds and are restrained by the curved surface of the cigarette gun inlet cone, and the cloth belt and the cigarette paper are gradually wrapped at the middle rear end of the cigarette tongue until the cigarette paper is U-shaped. After leaving the cigarette tongue, the cloth belt and the cigarette paper carry the cut tobacco to enter a channel formed by the small pressing plate and the inlet cone of the cigarette gun. The tobacco shreds expand for the first time in a channel formed by the small pressing plate and the cigarette gun inlet cone, and meanwhile, the inlet end of the small pressing plate wraps the cloth belt and the inner side edge of the cigarette paper, so that the cloth belt and the cigarette paper are gradually converted into 6 shapes from U shapes, and secondary compression is realized. When the cloth belt and the cigarette paper carry the tobacco shreds to leave the small pressing plate and enter the large pressing plate, the tobacco shreds expand for the second time. And (3) wrapping the outer side edge of the cloth belt along with the large pressing plate, wrapping the outer side cigarette paper edge on the inner side edge of the cigarette paper, performing third compression on the tobacco shreds, and bonding the outer side and the inner side of the cigarette paper together to form a cigarette strip. And when the cigarette strip leaves the large pressing plate, the cigarette strip slightly expands and is dried by a soldering iron, so that the cigarette strip is rolled and formed.

As shown in fig. 1-6, the cigarette rod rolling forming device of the present disclosure comprises a cigarette gun inlet cone 1, a wing plate mechanism, a tobacco pressing wheel 3, a cigarette tongue 4 and a small pressing plate 5.
The smoke gun channel of the smoke gun inlet cone 1 comprises an inlet section 11, a transition section 12 and an outlet section 13, wherein the inlet section 11, the transition section 12 and the outlet section 13 are connected in sequence.
The curvature of the entrance to the entry section 11 is greater than the curvature of the rest of the entry section 11. That is, the entrance to the entry section 11 is where the curvature of the entry section 11 is greatest. The curvature of the exit of the entry section 11 is less than the curvature of the transition section 12. The curvature of the transition section 12 increases gradually in the direction from the entry section 11 to the exit section 13. The exit section 13 includes a first exit section 131 and a second exit section 132. The first exit segment 131 is located between the second exit segment 132 and the transition segment 12, and the curvature of the first exit segment 131 gradually increases in a direction away from the transition segment 12, and the curvature of the second exit segment 132 remains unchanged. The arrangement of the curvature of the cigarette gun inlet cone 1 through the cigarette gun channel can effectively improve the stress uniformity of the cut tobacco in the cigarette rod rolling forming device. In specific implementation, in order to more effectively improve the stress uniformity of the cut tobacco, the curvature of the inlet section 11 may decrease first and then increase along the direction toward the transition section 12.

In order to improve the uniformity of the stress of the cut tobacco in the cigarette rod rolling forming device, the ratio of the lengths of the first inlet section 111 to the second inlet section 112 can be (1-2) to (3-4).
In one embodiment of the cigarette rod rolling forming device of the present disclosure, in order to more effectively improve the stress uniformity of the cut tobacco, the depth of the entering section 11 is decreased and then increased along the direction toward the transition section 12, and the depth of the transition section 12 is gradually decreased along the direction away from the entering section 11.

In one embodiment of the rod maker of the present disclosure, to more effectively promote tobacco stress uniformity, the curvature of the second exit segment 132 is greater than the curvature of the remainder of the garniture channel. That is, the curvature of the second exit segment 132 is the region of maximum curvature in the barrel passageway.
In one embodiment of the cigarette rod rolling forming device of the present disclosure, in order to more effectively improve the stress uniformity of the cut tobacco, the connection part of the entering section 11, the transition section 12 and the leaving section 13 is in smooth transition.
In one embodiment of the cigarette rod rolling forming device disclosed by the disclosure, in order to more effectively improve the stress uniformity of the cut tobacco, the ratio of the lengths of the entering section 11, the transition section 12 and the leaving section 13 is (5-8): (2-4): 3-4.
In one embodiment of the rod wrap forming device of the present disclosure, the wing mechanism 2 includes a front wing 21, a rear wing 22, and a connection assembly.
The front wing panel 21 includes a front passage section 211 and a front crimping section 212.

The thickness of the front filament pressing section 212 on the side adjacent to the cigarette gun inlet cone 1 is gradually reduced along the direction towards the cigarette gun inlet cone 1.
The rear wing panel 22 includes a rear pass section 221 and a rear hold-down wire section 222. The rear wire pressing section 222 is located at one end of the rear wing plate 22 far away from the wire suction forming groove, and the rear wire pressing section 222 corresponds to the wire pressing wheel 3.

The front passage section 211 and the rear passage section 221 form a passage area, and the front wire pressing section 212 and the rear wire pressing section 222 form a wire pressing area.
The distance between the front thread pressing section 212 and the rear thread pressing section 222 is gradually reduced in a direction away from the thread suction forming groove. The gradually decreasing thickness of the front and rear tobacco-pressing sections 212 and 222 on the side adjacent to the cigarette-gun inlet cone 1 in the direction toward the cigarette-gun inlet cone 1 facilitates better constraint of the tobacco between the front and rear wing plates 21 and 22, and the gradually decreasing distance between the front and rear tobacco-pressing sections 212 and 222 in the direction away from the tobacco-sucking forming groove facilitates more smooth application of pressure to the tobacco.
A connection assembly is located between the front wing panel 21 and the rear wing panel 22 and the connection assembly can be used to connect the front and rear pass-through sections 211 and 221.
The wing plate mechanism 2 enables the front wing plate 21 and the rear wing plate 22 to effectively restrain the cut tobacco through the thickness and distance design of the front tobacco pressing section 212 and the rear tobacco pressing section 222, and even if the gap at the joint of the wing plate mechanism 2 and the tobacco gun inlet cone 1 is enlarged, the cut tobacco cannot be restrained to generate an empty head.
Further, in order to balance the stress of the cut tobacco more effectively, the ratio of the lengths of the front passing section 211 and the front pressing section 212 is 2 (1-1.5), and the ratio of the lengths of the rear passing section 221 and the rear pressing section 222 is 2 (1.2-1.8).
Further, the ratio of the lengths of the front passing section 211 and the front wire pressing section 212 is 2:1.4, and the ratio of the lengths of the rear passing section 221 and the rear wire pressing section 222 is 2: 1.6.
Further, in order to balance the stress of the cut tobacco more effectively, the ratio of the distance between the side of the front tobacco pressing section 212 connected with the front passing section 211 and the side of the rear tobacco pressing section 222 connected with the rear passing section 221 to the distance between the side of the front tobacco pressing section 212 far away from the front passing section 211 and the side of the rear tobacco pressing section 222 far away from the rear passing section 221 is 1 (0.95-0.98).
Further, the connecting assembly includes a stopper 23, a first spacer 24, a pulley shaft 25, and a pulley 26.
The two ends of the first spacer 24 are respectively connected with the front wing plate 21 and the rear wing plate 22, and the stop 23 is arranged on the first spacer 24. The stop block 23 can pre-press the cut tobacco between the front wing plate 21 and the rear wing plate 22, so that the problem of cut tobacco deviation caused by deformation of a cut tobacco suction belt due to the force application of the cut tobacco by the cut tobacco pressing wheel 3 can be effectively solved, and the empty head rate is favorably reduced.
The pulley shaft 15 has both ends connected to the front wing plate 21 and the rear wing plate 22, respectively, and the pulley 26 is mounted on the pulley shaft 25.

The wear-resistant coating can be made of polytetrafluoroethylene, for example.
In one embodiment of the rod making and shaping device of the present disclosure, the length of the tongue body 41 is less than the length of the channel member 42 in order to better adjust the overall center of gravity of the tongue 4 and avoid the tongue 4 from shifting.

The curved matching surface 422 can better balance the acting force of the matching surface 422 from the inlet cone 1 of the tobacco pipe, thereby avoiding the deviation of the tobacco tongue 4 and achieving the purpose of improving the stress uniformity of the tobacco shreds.
Further, the curvature of the mating surfaces 422 on the end faces of the different sides of the channel member 42 are not the same.
In specific implementation, the ratio of the width of the mating surface 422 on the inlet side of the working groove 421 to the width of the mating surface 422 on the outlet side of the working groove 421 is 4: 1.
In one embodiment of the rod wrap forming device of the present disclosure, a line connecting the center of gravity of the body 41 of the cigarette tongue, the geometric center of the first working segment 4211 and the geometric center of the second working segment 4212 forms a triangle.
