Description

Technical Field

[0001] The present invention belongs to the field of new tobacco cigarette manufacturing equipment, and particularly relates to an automated aerosol-generating article rolling device and a rolling method. Background Art

[0002] In recent years, heated tobacco products have developed rapidly. Their usage method is to use a heating device to heat specially designed and manufactured cigarette sticks to generate an aerosol similar to that produced by the combustion of cigarettes for consumers to inhale. Since heated tobacco products do not burn tobacco during use, the harmful components in the smoke emissions are greatly reduced, which can reduce the health and safety risks of consumers, and thus are increasingly favored by consumers.

[0003] Due to the different smoke generation mechanisms of heated tobacco products and traditional cigarettes, there are significant differences in the structural design of their cigarette sticks. The resulting problem is that it is difficult for traditional cigarette machines to adapt to the small-batch production of various heated tobacco products. Existing technologies such as "CN107713003A Manual cigarette rolling device with a pressure rod" can only roll cigarette sticks with a fixed length and diameter, and the length and diameter dimensions of the rolled cigarette sticks are not precise enough. Moreover, the operation process is all manual, which is not suitable for laboratory sample preparation research.

[0004] Existing technologies such as "CN109998155A A semi-automatic cigarette bar machine" provide an automatic cigarette rolling machine that uses two cigarette rolling screws to drive cigarette rolling, and there is a power source between the screws. Although semi-automatic cigarette rolling is achieved, the tobacco feeding needs to be completed manually, and at the same time, the specifications cannot be flexibly changed, which is not suitable for laboratory cigarette rolling.

[0005] Existing technologies such as "CN101700141A An automatic cigarette rolling machine" disclose a cigarette rolling machine that can roll multiple tobacco sticks at one time, but empty cigarette tubes need to be prepared in advance and cannot be directly rolled starting from cigarette paper, and the specification switching is not flexible either.

[0008] The first rotating member and the second rotating member are arranged opposite to each other along a first direction and can move relative to each other in a relatively approaching or separating manner along the first direction;

[0009] At the position to be rolled, the rolling cloth sequentially bypasses the first rotating member and the second rotating member and can move between the first rotating member and the second rotating member;

[0010] In the position to be rolled, the ends of the first centering rod and the second centering rod are arranged relatively opposite to each other along the second direction, and are pressed on the roll cloth between the first rotating member and the second rotating member along the second direction to form a depression in the roll cloth, and the distance between the first centering rod and the second centering rod in the second direction is used to place the material to be rolled, and the first rotating member and the second rotating member are relatively close to each other along the first direction, so that the roll cloth wraps the first centering rod and the second centering rod, and the material to be rolled is rolled by moving the roll cloth between the first rotating member and the second rotating member, wherein the first direction is perpendicular to the second direction.

For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0090] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0091] Please refer to Figures 1 - 3The present invention provides a rolling device for an aerosol-generating product, the device comprising a first rotating member 1, a second rotating member 2, a rolling cloth 3, a first centering rod 4 and a second centering rod 5, wherein the first rotating member 1 and the second rotating member 2 are arranged opposite to each other along a first direction, and the first direction is, for example, Figure 1 , Figure 8 , Figure 17 , Figure 29 In the X direction of the drawing, the first rotating member 1 and the second rotating member 2 can be relatively displaced along the first direction in a manner of approaching or moving away from each other; in the waiting rolling position, the cloth 3 sequentially bypasses the first rotating member 1 and the second rotating member 2 and can move between the first rotating member 1 and the second rotating member 2, and in the waiting rolling position, the first centering rod end 4.1 and the second centering rod end 5.1 are arranged relatively along the second direction, and the second direction is, for example, Figure 1 , Figure 3 or Figure 9 The first centering rod 4 and the second centering rod 5 are pressed on the cloth roll 3 between the first rotating member 1 and the second rotating member 2 along the second direction to make the cloth roll 3 form a depression. The spacing d between the first centering rod 4 and the second centering rod 5 in the second direction is used to place the material to be rolled, such as loose materials such as tobacco or tobacco powder. The material to be rolled is relatively close to the first rotating member 1 and the second rotating member 2 along the first direction, so that the cloth roll wraps the first centering rod 4 and the second centering rod 5, and the cloth roll 3 is moved between the first rotating member 1 and the second rotating member 2 to roll the material to be rolled. The movement method can be from the first rotating member 1 to the second rotating member 2. In this embodiment, the cloth roll 3 moves back and forth between the first rotating member 1 and the second rotating member 2. Among them, the X direction of the present application is the same as that of the embodiment of the present invention. Figure 1 The width direction of the bottom plate 48 is parallel to each other, and the Y direction is parallel to the length direction of the bottom plate 48, wherein the first direction is perpendicular to the second direction. Furthermore, the first direction and the second direction are both horizontal directions. When the loose material is rolled into a columnar material, the wrapping paper can be placed in the above-mentioned depression, and the wrapping paper and the columnar material can be twisted and connected into the form of a cigarette by moving the rolling cloth 3 back and forth.

[0092] The aerosol-generating product rolling device provided by the present invention adopts a rolling cloth, and the flexible rolling cloth can adapt to cigarettes of different diameters, and the rolling is performed by gathering and moving the rolling cloth. In addition, materials are placed on the rolling cloth, and the length of the rolled cigarette can be controlled by controlling the distance between the two centering rods. The aerosol-generating product rolling device of the present application can automatically roll cigarettes of different diameters and lengths as needed, and is particularly suitable for laboratory proofing, such as cigarette product development, process improvement, material testing, and the like.

[0093] refer to Figures 4 - 7 Recombination Figures 10 - 12, the first rotating member 1 and the second rotating member 2 are respectively fixed in the first bearing housing 6 and the second bearing housing 12 through the first bearing 6.1, the second bearing 12.1 and the first bearing spacer 6.2, the second bearing spacer 12.2. The first bearing housing 6 and the second bearing housing 12 are respectively connected to the first plate 7 and the second plate 10, and the first plate 7 and the second plate 10 are respectively located on the first linear guide rail 8 and the second linear guide rail 11. In addition, the first plate 7 is clamped with the groove of the nut connecting plate 13, and the nut connecting plate 13 is nested on the screw rod of the first closed-loop stepper motor 17. The second plate 10 includes a cylinder connecting plate 7, which is connected to the cylinder 28 and the second proximity sensor 29 and can be used to drive the second plate 10 to move along the first direction. During the rolling process, driven by the first closed-loop stepper motor 17 and / or the cylinder 28, the first rotating member 1 moves relatively closer to the second rotating member 2 along the first direction, so that the rolling cloth 3 wraps the first centering rod 4 and the second centering rod 5 and forms a cylindrical cavity. The cavity is used to place materials such as loose materials like tobacco shreds and tobacco powder. Then, the loose materials are rolled into a cylindrical material by the back-and-forth movement of the rolling cloth 3. After the rolling is completed, driven by the first closed-loop stepper motor 17 and / or the cylinder 28, the second rotating member 2 and the first rotating member 1 move relatively away from each other along the first direction, so that the first centering rod 4 and the second centering rod 5 rise and leave the rolling cloth 3. Among them, the first proximity sensor 17.1 realizes the precise control of the movement. After that, driven by the first closed-loop stepper motor 17 and / or the cylinder 28, the first rotating member 1 and the second rotating member 2 move relatively along the first direction, so that the rolling cloth 3 between the first rotating member 1 and the second rotating member 2 is in a tensioned state. Then, by means of relative movement, the rolled aerosol generating article can slide along the gap between the second rotating member 2 and the second plate 10 to the blanking plate 24. Exemplarily, the way that the first rotating member 1 and the second rotating member 2 generate relative movement can be that the first rotating member 1 is fixed and the second rotating member 2 moves closer to the first rotating member 1 along the first direction.

[0094] Furthermore, the first rotating member 1 and the second rotating member 2 are drums, specifically the first drum and the second drum. The first drum and the second drum are parallel to each other, and their axial directions are parallel to the second direction. Using drums can reduce the friction force when the rolling cloth 3 moves, making the rolling cloth 3 not easily worn.

[0095] Reference Figures 8 - 12 And in combination with Figure 2, Further, the above-mentioned rolling device further includes a rewinding and unwinding mechanism 14 and a counterweight 15. The rewinding and unwinding mechanism 14 is used for rewinding and unwinding the rolling cloth 3. Along the moving direction of the rolling cloth 3, the rolling cloth 3 has opposite first end 3.1 and second end 3.2. The first end is wound around the rewinding and unwinding mechanism 14, and the second end 3.2 is the moving end. Further, the moving end can be connected to the counterweight 15, and the counterweight 15 falls by its own weight to pull the rolling cloth 3. The rewinding and unwinding mechanism 14 unwinds the rolling cloth 3 for movement, and the rewinding and unwinding mechanism 14 can also drive the rolling cloth 3 to return by rewinding, and move back and forth like this for rolling. The gravity of the counterweight 15 is the tension of the rolling cloth 3, so that the rolling cloth 3 can be subjected to a constant tension, and in this way, the aerosol generating article can be rolled in a constant tension environment. Further, the counterweight 15 can change its own weight by hanging weights of different weights, so as to meet the requirements of different cigarette tension environments. Continue to refer to Figures 8 - 9 , the counterweight includes a counterweight roller shaft 15.1, and the counterweight roller shaft 15.1 is connected to the counterweight roller bearing 15.2 and fixed together in the limiting groove 16. The limiting groove 16 extends in the vertical direction. For example Figure 2 , Figure 8 and Figure 9 the Z direction shown. The Z direction in this application is perpendicular to the X and Y directions. Among them, there are multiple round holes on the counterweight roller shaft 15.1. Exemplarily, there are 5 round holes. The middle three round holes can fix the second end 3.2 of the rolling cloth 3 on the counterweight roller shaft 15.1 through screws, and the round holes on both sides are used for hanging weights. Further, both ends of the counterweight roller shaft 15.1 are located in the limiting groove 16. Under the action of the counterweight 15, the rolling cloth 3 moves along the vertical extension direction of the limiting groove 16. The limiting groove 16 can prevent the counterweight 15 from swinging in the width direction of the limiting groove 16, for example, in the X direction shown in Figure 8 , which is convenient for the rolling cloth 3 to be rolled under a constant tension.

[0096] Continue to refer to Figures 8 - 12 and in combination with Figure 2, wherein, the fabric rewinding and unwinding mechanism 14 includes a fabric roll shaft 14.1, the fabric roll shaft 14.1 includes a plurality of round holes, the first end 3.1 of the fabric 3 is clamped by screws to hold the fabric 3 and fix it on the fabric roll shaft 14.1. Both sides of the fabric roll shaft 14.1 are nested in the anti-deviation ring 14.2, which can be used to prevent the fabric 3 from deviating and prevent the fabric from wrinkling during the winding process. In addition, both ends of the fabric roll shaft 14.1 are fixed on the first support 18. Further, the fabric roll shaft 14.1 is connected to the synchronous pulley 21 through the third bearing 20. The synchronous belt 53 on the synchronous pulley 21 is connected to the second closed-loop stepper screw motor 19. The fabric roll shaft 14.1 rotates self-driven by the second closed-loop stepper motor 19, so that the fabric 3 is wound and wrapped around its outer cylindrical surface. Then the synchronous belt 53 drives the synchronous pulley 21 to rotate, and further the synchronous pulley 21 drives the fabric roll shaft 14.1 to wind and unwind. Among them, the first support 18 is connected to the first substrate 22, and the first plate 7 and the first substrate 22 are connected through the nut connecting plate 13 and the first closed-loop stepper screw motor 17. During the winding stage, the fabric roll shaft 14.1 slowly unwinds to cooperate with the winding. When the winding is completed, it quickly winds back to wait for the winding of the next aerosol generating article.

[0097] Referring to Figure 2 and in combination with Figures 8 - 9 and Figure 12 , the winding device further includes a third rotating member 23. The third rotating member 23 is located on the side of the second rotating member 2 away from the first rotating member 1 in the first direction and is spaced from the second rotating member 2 along the first direction. The second end 3.2 of the fabric 3 bypasses the third rotating member 23 and is connected to the counterweight 15. Further, the fabric 3 between the third rotating member 23 and the counterweight 15 extends along the third direction, such as Figure 2 or Figures 8 - 9 the Z direction shown. In the present application, the Z direction is perpendicular to the X direction and the Y direction. Such a setting can facilitate the rising and falling of the fabric 3, and at the same time can prevent the fabric 3 from contacting the limit groove 16 when moving, thus causing wear. Further, the blanking plate 24 abuts against the fabric 3 wound around the third rotating member 23 for receiving the winding material transferred from the fabric 3. Among them, both ends of the third rotating member 23 are fixed in the second support 26 through the fixed roller bearing 25. In particular, the third rotating member 23 is a roller, which can reduce the friction generated by the movement of the fabric 3 and make the fabric 3 not easily worn. Further, there are relatively large gaps left in the mounting holes of the second support 26 and the second substrate 27, which can be used to adjust the parallelism between the first rotating member 1 and the second rotating member 2.

[0098] Refer to Figure 23, in the above embodiment, after the loose cut tobacco 51 is rolled into a cylindrical material, the wrapper 52 can be placed in the recess of the cloth roller 3, that is, on the cloth roller 3 between the first centering rod 4 and the second centering rod 5. At this time, the side wall of the cylindrical material clamped by the first centering rod 4 and the second centering rod 5 will be in close contact with one side of the wrapper 52. Under the action of tension, the cloth roller 3 drives the first centering rod 4 and the second centering rod 5 to rotate synchronously by moving back and forth, and at the same time drives the wrapper 52 and the cylindrical material to rotate synchronously, so as to twist and connect the cylindrical material and the wrapper 52 into a cigarette. In particular, the wrapper 52 is a wrapper 52 that has been coated with glue. It should be noted that during the entire rolling process (including the process before rolling, during rolling, and after rolling), the first rotating member 1 and the second rotating member 2 can move closer to or away from each other along the first direction at the same time, or any one of the rotating members can move closer to or away from the other rotating member along the first direction, which is not limited here.

[0099] Figures 27 - 40 FIG. 4 is an overall structural schematic diagram and an overall structural top view of a rolling device for an aerosol generating article according to another embodiment of the present application. The rolling device can adopt the structures in the above embodiments, for example, it also includes a first centering rod 4, a cloth roller 3, and a second centering rod 5. The difference is that this embodiment further includes a first receiving plate 33.1 and a second receiving plate 34.1 arranged oppositely along the first direction. The first rotating member 1 and the second rotating member 2 are respectively a first roller 33.2 and a second roller 34.2 in this embodiment. The cloth roller 3 is laid flat on the first receiving plate 33.1, bypasses the first roller 33.2 and the second roller 34.2, and then is laid flat on the second receiving plate 34.1.

[0100] Furthermore, the above embodiment also includes a first winding and unwinding mechanism 31, a second winding and unwinding mechanism 32, a fourth rotating member 35, and a blanking area 36. Among them, along the moving direction of the cloth roller 3, the cloth roller 3 has opposite first end 3.1 and second end 3.2. The first end 3.1 is wound around the first winding and unwinding mechanism 31, and the second end 3.2 is wound around the second winding and unwinding mechanism 32. Both the first winding and unwinding mechanism 31 and the second winding and unwinding mechanism 32 are driven by a closed-loop stepping screw motor; both the first receiving plate 33.1 and the second receiving plate 34.1 are parallel to the first direction and the second direction. The first roller 33.2 and the second roller 34.2 are located between the first receiving plate 33.1 and the second receiving plate 34.1 along the first direction. At the position to be rolled, the cloth roller 3 is continuously laid flat on the first receiving plate 33.1, the first roller 33.2, the second roller 34.2, and the second receiving plate 34.1 in sequence. The first roller 33.2 is fixed at one end of the first receiving plate 33.1 along the first direction to form the first platform 33, and the second roller 34.2 is fixed at one end of the second receiving plate 34.1 along the first direction to form the second platform 34. The cloth roller 3 can move back and forth between the first platform 33 and the second platform 34.

[0101] Further, the loose cut tobacco 51 can be placed on the wrapping cloth 3 between the first centering rod 4 and the second centering rod 5. Driven by the motor, the first roller 33.2 moves closer to the second roller 34.2 in the first direction, such as Figure 29 the X direction shown, where the second roller 34.2 can be fixed until the wrapping cloth 3 wraps the first centering rod 4 and the second centering rod 5. Driven by the motor, the wrapping cloth 3 rolls the loose cut tobacco 51 into a cylindrical material by moving back and forth. Then, the wrapping paper 52 can be placed in the recess of the wrapping cloth 3, that is, on the wrapping cloth 3 between the first centering rod 4 and the second centering rod 5. At this time, the side wall of the cylindrical material clamped by the first centering rod 4 and the second centering rod 5 will closely adhere to one side of the wrapping paper 52. Driven by the motor, the wrapping cloth 3 drives the first centering rod 4 and the second centering rod 5 to rotate synchronously by moving back and forth, and at the same time drives the wrapping paper 52 and the cylindrical material to rotate synchronously to twist and connect the cylindrical material and the wrapping paper 52 into a cigarette. In particular, the wrapping paper 52 is a wrapping paper 52 with glue applied.

[0102] In addition to the above method of placing the wrapping paper 52 in the recess for rolling, in this embodiment, the wrapping paper 52 can also be placed on the second platform 34 to complete the rolling process by twisting. The specific process is as follows: At the position to be rolled, the first platform 33 and the second platform 34 are flush in the third direction. The loose material is placed within the distance between the first centering rod 4 and the second centering rod 5 in the second direction. Then, driven by the motor, the first roller 33.2 moves closer to the second roller 34.2 in the first direction so that the wrapping cloth 3 wraps the first centering rod 4 and the second centering rod 5, and the wrapping cloth 3 rolls the material to be rolled by moving back and forth between the first rotating member 1 and the second rotating member 2 until the loose material is rolled into a cylindrical material. Then, the first platform 33 and the second platform 34 move relative to each other in the third direction so that the first platform 33 is higher than the second platform 34 in the third direction. For example, referring to Figure 29 and Figure 33, the lifting of the first platform 34 causes the first platform 33 to be higher than the second platform 34. The first centering rod 4 and the second centering rod 5 clamp the cylindrical material and move it towards the bottom surface of the first platform 33. Alternatively, it can also be that the first platform 33 is lifted in the third direction and then moves closer to the second platform 34 along the first direction, so that the first centering rod 4, the second centering rod 5, and the cylindrical material are located below the first platform 33. Place the wrapping paper 52 on the second platform 34 and apply glue to the wrapping paper 52. The second platform 34 is provided with a negative pressure area, which can adsorb and fix the wrapping paper 52 on the second platform 34. Then, driven by the motor, the first platform 33 and the second platform 34 move closer to each other along the first direction. Specifically, the first platform 33 moves, and the second platform 34 remains stationary. The first platform 33 moves horizontally towards the second platform 34, driving the cloth roll 3 to move. The cloth roll 3 is in a folded state. Under the pulling of the first platform 33, the upper half of the cloth roll 3 covers the cloth roll 3 located on the second platform 34. The cylindrical material is wrapped by the folded cloth roll 3. Through the movement of the cloth roll 3, rubbing occurs between the upper and lower parts of the folded cloth roll 3, thereby driving the cylindrical material to roll towards the wrapping paper 52 placed on the second platform 34 for rubbing and joining. At this time, the cylindrical material and the glued wrapping paper 52 are bonded together. As the cloth roll 3 moves, it drives the cylindrical material and the wrapping paper 52 to be rubbed and joined, and the rolling process is completed through this rubbing and joining method. During the above rolling process, it can be that the second platform 34 remains stationary, and the first platform 33 moves closer to the second platform 34 along the horizontal direction. The moving directions include the first direction and the third direction, that is, the first platform 33 can move closer to and away from the second platform 34 along the first direction, and can also rise or fall along the third direction. The third direction is, for example Figure 29 the Z direction shown, and the second direction is, for example Figure 28 the Y direction shown, and the first direction is, for example Figure 29 the X direction in

[0103] Furthermore, in the above embodiment, when the first centering rod 4 and the second centering rod 5 clamp the cylindrical material and roll it towards the second platform 34, the first centering rod 4 and the second centering rod 5 can move synchronously with the movement of the first platform 33 along the first direction, preventing the cut tobacco 51 from falling on the cloth roll 3.

[0104] Referring to Figure 29 , the above rolling device further includes a fourth rotating member 35 and a blanking area 36. The fourth rotating member 35 is provided at the other end of the second receiving plate 34.1 along the first direction. At the position to be rolled, the cloth roll 3 bypasses the fourth rotating member 35 from the second receiving plate 34.1, and the material completed in the above rolling process falls into the blanking area 36 through the guidance of the fourth rotating member 35 on the cloth roll 3.

[0105] Referring to Figures 13 - 14, in the above embodiments, the first centering rod 4 and the second centering rod 5 are respectively connected to the double-row angular contact bearing 38.1, which can reduce the frictional force generated by rotation. The first centering rod 4 and the second centering rod 5 can also be driven to rotate actively by themselves, and the rotation speed can be adjusted. They are further fixed in the fixed bracket 38 through the bearing gland 38.2 and the R-type radial locking round nut 38.3. The first centering rod 4 and the second centering rod 5 are detachably connected to the fixed bracket 38, which is convenient for replacing centering rods of different diameters.

[0106] Referring to Figures 15 - 16 , in the above embodiments, it further includes a lifting and translation mechanism 55. Referring to Figures 15 - 16 , the ends of the first centering rod 4 and the second centering rod 5 are located on the first slider seat 40 and the second slider seat 41 of the third linear guide rail 39 along the second direction. The third linear guide rail 39 is installed on the seat plate 54, and the seat plate 54 is connected to the linear ball bearing 49. The first slider seat 40 and the second slider seat 41 are respectively nested on the screws of the third closed-loop stepper motor 42 and the fourth closed-loop stepper motor 43. The third closed-loop stepper motor 42 and the fourth closed-loop stepper motor 43 are used to drive the first centering rod 4 and the second centering rod 5 to move along the first direction or the second direction. The third proximity sensors 44 and the fourth proximity sensors 45 on the third closed-loop stepper motor 42 and the fourth closed-loop stepper motor 43 can achieve precise control of the movement. The third linear guide rail 39 is connected to the nut pusher block 46 along the third direction, and the nut pusher block 46 is nested on the screw of the fifth closed-loop stepper motor 47. This connection method enables the first centering rod 4 and the second centering rod 5 to move along the third direction under the drive of the fifth closed-loop stepper motor 47. The lifting and translation mechanism 55 further includes a fifth proximity sensor 50 for achieving precise control of the movement along the third direction.

[0107] Furthermore, referring to 1 and Figure 27 , the above cigarette rolling device further includes a feeding bin 37 for accommodating the material to be rolled. The rolling cloth 3 has a placement area 30 for the material to be rolled, and the material to be rolled can be put into the placement area 30 for the material to be rolled through a mechanical gripper.

[0108] The cigarette rolling device for aerosol generating articles disclosed in the present application can automatically roll cigarettes of different diameters and sizes, and can roll the required specifications through precise control, which is especially suitable for laboratory proofing.

[0109] Next, in combination with Figures 17 - 26 , the first method for rolling an aerosol generating article disclosed in the present application is introduced as follows:

[0110] Put the cut tobacco 51 in the feeding bin 37 between the first centering rod 4 and the second centering rod 5 through a mechanical gripper. The rolling device in this embodiment is at the position to be rolled, such asFigures 17 - 18 As shown, the first rotating member 1 and the second rotating member 2 are arranged oppositely along the first direction, the ends of the first centering rod 4 and the second centering rod 5 are arranged oppositely along the second direction, and are pressed against the fabric roll 3 located between the first rotating member 1 and the second rotating member 2 along the second direction, so that the fabric roll 3 forms a depression. The distance d between the first centering rod 4 and the second centering rod 5 in the second direction is used to place the material to be rolled. Then, the first rotating member 1 and the second rotating member 2 generate relative displacement in a mutually approaching manner along the first direction until the first centering rod 4 and the second centering rod 5 are wrapped by the fabric roll 3. The fabric roll 3 wraps the first centering rod 4 and the second centering rod 5 to form a cylindrical cavity, and the cavity is used to place cut tobacco 51. The state is as Figures 19 - 20 shown; under the action of gravity, the weights on the counterweight 15 cause the fabric roll 3 to be subjected to a constant tension. By unwinding the fabric roll 3 from the fabric roll shaft 14.1, the second end 3.2 of the fabric roll 3 moves downward along the vertical extension direction of the limit groove 16. The state is as Figures 21 - 22 shown; after the unwinding is completed, the second closed-loop stepper screw motor 19 drives the fabric roll shaft 14.1 to wind up. The weights on the counterweight 15 move upward along the extension direction of the limit groove 16. Through unwinding and winding up, the fabric roll 3 moves back and forth between the first rotating member 1 and the second rotating member 2. The inner diameter of the cylindrical cavity formed by the fabric roll 3 wrapping the first centering rod 4 and the second centering rod 5 continuously decreases, and the degree of fit between the fabric roll 3 and the first centering rod 4 and the second centering rod 5 continuously increases, so that the loose cut tobacco 51 is rolled into a cylindrical tobacco material and the diameter of the cylindrical tobacco material is consistent with the diameter of the centering rod. The distance between the first centering rod 4 and the second centering rod 5 in the second direction can be adjusted, so that cylindrical materials of different lengths can be rolled.

[0111] As Figures 23 - 24 shown, after the above process is carried out, the wrapper paper 52 is placed. The wrapper paper 52 is placed between the first rotating member 1 and the second rotating member 2; and within the distance d between the first centering rod 4 and the second centering rod 5. The cylindrical material is adhered to one side of the wrapper paper 52, and then one or more winding and unwinding movements are carried out. The first centering rod 4 and the second centering rod 5 clamp the cylindrical tobacco material and drive the wrapper paper 52 to rub and connect to form a cigarette. As Figures 25 - 26 shown, after the rolling is completed, the cylinder 28 and / or the first closed-loop stepper screw motor 17 drive the first rotating member 1 and the second rotating member 2 to move relatively away from each other along the first direction until the fabric roll 3 between the first rotating member 1 and the second rotating member 2 is in a tensioned state. Then, through the movement of the fabric roll 3, the rolled smoke section 56 is driven to move, from the second rotating member 2 to the third rotating member 23, and then fall onto the blanking plate 24, so as to be transferred to the next process, and the entire rolling process is completed.

[0112] As Figures 27 - 40 shown, the present application also discloses another method for rolling an aerosol generating article, and the method is as follows:

[0113] At the position to be wound, the first platform 33 and the second platform 34 are arranged at intervals in the first direction. The cut tobacco 51 in the feeding bin 37 is placed on the winding cloth 3 between the first platform 33 and the second platform 34 by means of a mechanical gripper, and is also located within the distance d between the first centering rod 4 and the second centering rod 5. The state is as shown in Figures 27 - 28 shown; the second platform 34 is fixed, and the first platform 33 moves relatively closer to the second platform 34 in the first direction until the first centering rod 4 and the second centering rod 5 are wrapped by the winding cloth 3. The winding cloth 3 wraps the first centering rod 4 and the second centering rod 5 to form a cylindrical cavity for placing the cut tobacco 51. The state is as shown in Figures 29 - 30 shown; the first platform 33 and the second platform 34 continue to approach. Driven by the motor, the first winding and unwinding mechanism 31 and the second winding and unwinding mechanism 32 perform multiple repeated winding and unwinding operations, so that the inner diameter of the cylindrical cavity formed by the winding cloth 3 wrapping the first centering rod 4 and the second centering rod 5 continuously decreases, and the degree of fitting between the winding cloth 3 and the first centering rod 4 and the second centering rod 5 continuously increases, so that the loose cut tobacco 51 is wound into a cylindrical tobacco material and the diameter of the cylindrical tobacco material is consistent with the diameters of the first centering rod 4 and the second centering rod 5. The state is as shown in Figures 31 - 32 shown; then, the second platform 34 is fixed, and the first platform 33 is lifted along the third direction so as to be higher than the second platform 34 and moves in the first direction towards the second platform 34. Its state is as shown in Figures 33 - 34 shown. Then, the wrapper paper 52 is placed on the second platform 34 by a manipulator and the wrapper paper 52 is glued. The state is as shown in Figures 35 - 36 shown. Then, the first platform 33 continues to move in the first direction, for example, Figure 37 moving leftward in. The first centering rod 4 and the second centering rod 5, as well as the clamped cylindrical tobacco material and the first platform 33, all move along the first direction. The movement of the winding cloth 3 drives the cylindrical material to roll towards the wrapper paper 52 placed on the second platform 34. The glued wrapper paper 52 and the cylindrical material are bonded together. The movement of the winding cloth 3 drives the cylindrical material to rotate synchronously, and the cylindrical material and the wrapper paper 52 are spliced together by the rubbing of the winding cloth 3 to complete the splicing. The state is as shown in Figures 37 - 38 shown. After the winding is completed, the first platform 33 continues to move in the first direction towards the fourth rotating member 35, and bypasses the fourth rotating member 35 to introduce the wound material, that is, the smoking section 56, into the blanking area 36. The state is as shown in Figures 39 - 40 shown; wherein, the fourth rotating member 35 is a roller. The winding device in this embodiment has a good splicing effect on the cut tobacco 51 and the wrapper paper 52, and the winding device runs relatively stably.
