Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco processing equipment, in particular to a composite section splicing device in an aerosol generating product. Background Art

[0002] In recent years, with the development of science and technology and the increasing attention of consumers to new things, new cigarettes have emerged in an endless stream, and the requirements for filter rods for cigarettes have become increasingly higher. The flexible and changeable design requirements and the pursuit of effectiveness in the preparation of multi-component composite filter rods have made the demand for filter rod composite equipment more urgent. Developing a filter rod forming equipment that is suitable for a variety of diameter specifications and can realize the composite of base rods of different lengths according to design requirements can solve the above problems, but the filter rod forming equipment currently on the market is basically equipped for production, and lacks convenient equipment suitable for laboratory experiments.

[0003] At present, the splicing devices used in the market mainly use splicing drums and rubbing plate devices to splice filter rods or cigarettes into shape.

[0004] For example, patent CN215013547U discloses a new type of rubbing board and a rubbing device, including a rubbing board body, the rubbing board body having a rubbing surface, characterized in that the rubbing surface is arc-shaped, and the circumference of the rubbing surface and the circumference of the cigarette rubbing wheel are concentric circles; and the rubbing surface satisfies the following relationship: L≥1.5C and β<α, L is the arc length of the rubbing surface, C is the circumference of the cigarette group cross-section, α is the arc angle of the cigarette rubbing wheel between two adjacent cigarette grooves, and β is the arc angle of the rubbing surface.

[0005] For another example, patent CN209284307U discloses a splicing component for cigarettes or filter rods, which is assembled on a splicing machine and used in conjunction with a splicing wheel. It comprises a rubbing board body and a scraper at the lower end thereof movably connected thereto. The rubbing board body comprises a middle section and symmetrically arranged left and right sections. The characteristic is that the surfaces of the left and right sections respectively have a groove A lower than the surface of the middle section, and a flexible gasket is provided in the groove A.

[0006] like Figure 1 As shown, the prior art uses a splicing wheel 01 and a splicing plate 02 to splice the filter rod 03. Since the splicing wheel 01 and the splicing plate 02 are both fixed mechanical structures, when the diameter of the filter rod 03 needs to be changed, the entire device needs to be disassembled or replaced with other devices, which is costly and inconvenient. However, the present application uses a splicing cloth to replace the splicing wheel 01 and the splicing plate 02, which can better adapt to the splicing of composite sections of aerosol generating products with different diameters.

[0007] The splicing devices in the prior art all adopt the form of splicing drums and rubbing plates. These devices are mainly used in the production equipment for splicing cigarettes and composite filter rods. The equipment is relatively complex and large. When encountering samples of different lengths, different diameters and different tipping paper widths, it is necessary to adjust many parts to adapt. In some cases, it is even necessary to significantly adjust the splicing structure design to suit the trial production of samples of different specifications. For the splicing of filter rods of one diameter specification, one specification part is required. For laboratory samples, the above splicing equipment is not only expensive, but also has a long equipment adjustment cycle when the cigarette specifications are switched, which is not conducive to flexible and flexible samples.

[0117] The following is an explanation of the implementation of the present invention by specific specific embodiments. Those skilled in the art can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this utility model are limited to this implementation. On the contrary, the purpose of introducing the utility model in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that, in the absence of conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0118] The term "composite segment in an aerosol-generating article" is used herein to describe a filter plug segment and a smoking unit segment of an aerosol-generating article to be twisted together.

[0119] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0120] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0121] The present embodiment provides a splicing device for splicing a composite section in an aerosol generating product, comprising a splicing unit 1, wherein the splicing unit 1 comprises a first splicing platform 11, a second splicing platform 12, a reel 13, and a splicing cloth 14, wherein the first splicing platform 11 is used to be covered by the splicing cloth 14, and a plugging paper for splicing is placed on the covered splicing cloth 14; the second splicing platform 12, the first splicing platform 11 and the second splicing platform 12 can move in a first direction in a direction of relatively approaching or moving away from each other; the reel 13 is used to roll up or unwind the splicing cloth; the splicing cloth 14 is continuously spread along the first direction on the first splicing platform On the platform 11 and the second splicing platform 12, a splicing cloth 14 is fixed at one end along the first direction and wound on the reel 13 at the other end, and the splicing cloth 14 is used to place the composite section; in the position to be spliced, the second splicing platform 12 is staggered or spaced relative to the first splicing platform 11 in the first direction, and is higher than the first splicing platform 11 in the second direction, and the first splicing platform 11 and the second splicing platform 12 move in a relatively close direction along the first direction, driving the splicing cloth 14 to wrap the composite section, and the splicing cloth 14 drives the composite section to roll toward the tipping paper to complete the splicing, wherein the first direction and the second direction are perpendicular.

[0122] By adopting the above technical scheme, the splicing and forming of composite segments in aerosol generating products of different diameters can be matched, the splicing of composite segments and the wrapping of forming paper can be realized, and the adaptability of the device to the splicing of composite segments of different diameters can be improved.

[0123] In order to prepare composite segment samples with different diameters, different tensions of the splicing cloth 14 can be designed according to different diameters, which can better meet the splicing requirements of composite segment samples with different diameters.

[0124] Among them, the composite segment is a plurality of independently separated parts, for example, it includes a plurality of filter rods of different materials and functions, which are used to prepare composite filter rods. The composite segment can also be a combination of a filter rod and a smoking segment, which is used to splice a cigarette. The composite segment can also be a combination of a filter rod, a support segment and a cooling segment. Before splicing begins, the composite segment loading robot places the arranged composite segments in the composite segment placement area of ​​the splicing cloth in a set order. Through splicing, the multiple independent composite segments are wrapped by the tipping paper and rolled into a complete composite filter rod or cigarette.

[0125] The splicing cloth 14 is made of a flexible material, and the splicing cloth 14 material can be, for example, polytetrafluoroethylene, specifically polytetrafluoroethylene insulating cloth. Since the splicing cloth 14 is a flexible and soft component, it can adapt to wrapping composite segments of different diameters. When the second splicing platform 12 moves, the splicing cloth 14 wraps the composite segment and moves, so that the forming paper wraps the composite segment to complete the splicing. The splicing cloth is a flexible and soft cloth, and has stronger adjustability and adaptability than a rigid splicing wheel.

[0126] Furthermore, by adjusting the tension of the splicing cloth 14, the splicing of composite segments of different diameters can be matched. When a composite segment with a relatively small diameter needs to be spliced, the tension of the splicing cloth 14 is increased. When a composite segment with a relatively large diameter needs to be spliced, the tension of the splicing cloth 14 is reduced. During the splicing process, after the composite segment loading manipulator places the composite segment into the receiving groove 152 or the composite segment placement area 151 of the splicing unit 1, and after the first centering rod 21 and the second centering rod 22 withdraw from the receiving groove 152, the reel motor can control the splicing cloth 14 to maintain a tensioned state through torque, and the tension can be adjusted at this time. During the splicing process, the splicing cloth 14 is close to the composite segment, and when a composite segment with a small diameter needs to be spliced, the tension is increased. On the contrary, when a composite segment with a larger diameter needs to be spliced, the tension of the splicing cloth 14 is reduced, thereby achieving adaptive splicing of composite segments with different diameters without changing the mechanical structure or disassembling the mechanical structure of the splicing device. Furthermore, since the splicing is performed by wrapping the composite section with a splicing cloth, the splicing of composite sections with different lengths can also be adapted.

[0127] The first direction may be a horizontal direction, and correspondingly, the second direction may be a vertical direction. Figure 2 , Figure 3 and Figure 8The x direction and the second direction are Figure 2 , Figure 3 and Figure 4 z direction.

[0128] like Figure 2 As shown, in one embodiment, the first splicing platform 11 is a fixed platform, the second splicing platform 12 is a mobile platform, and the second splicing platform 12 includes a mobile flat plate 121 and a splicing roller 122. The splicing roller 122 is located at the splicing front end of the mobile flat plate 121, parallel to the mobile flat plate 121 and perpendicular to the first direction. In the splicing position, the splicing cloth 14 extends from the splicing rear end of the mobile flat plate to the splicing front end, bypasses the splicing roller 122 and falls to the first splicing platform 11 along the second direction, and moves toward the first splicing platform 11 along the first direction through the mobile flat plate 121 and the splicing roller 122, driving the splicing cloth 14 to complete the splicing. Among them, the first splicing platform 11 and the second splicing platform 12 are parallel to the first direction and the third direction. Further, the first splicing platform 11 and the second splicing platform 12 are parallel to the horizontal plane. The second front end 123 is the splicing front end of the above-mentioned mobile flat plate 121. The splicing roller 122 extends along the third direction. Among them, the third direction is Figure 2 , Figure 4 and Figure 8 The y direction in the C direction is Figure 3 , Figure 8 , Fig. 9 , Fig.11 , Fig.13 , Fig.15 , Fig.17 , Fig.19 , Fig.21 and Fig.23 The C direction in the drawing. The negative pressure port 18 on the first splicing platform 11 is used to adsorb and fix the tipping paper 06 on the first splicing platform 11. The tipping paper 06 is placed on the first splicing platform 11, and the tipping paper 06 is glued by the gluing mechanism. Afterwards, driven by the motor, the second splicing platform 12 and the first splicing platform 11 move relative to each other in a close manner. Specifically, the second splicing platform 12 moves toward the first splicing platform 11 along the C direction, and the first splicing platform 11 remains stationary, thereby driving the splicing cloth 14 to move. The splicing cloth 14 is in a folded state, and under the pull of the second splicing platform 12, the upper half of the splicing cloth 14 is driven to cover the splicing cloth 14 located on the first splicing platform 11, and the composite section 05 is wrapped by the folded splicing cloth 14. Through the movement of the splicing cloth 14, the upper and lower parts of the folded splicing cloth 14 are spliced, thereby driving the composite section 05 to roll toward the tipping paper 06 placed on the first splicing platform 11 for splicing. The spliced ​​composite section 05 slides down the slope 16 to complete the discharge.

[0129] In another embodiment, the first splicing platform 11 and the second splicing platform 12 are both mobile platforms, and the first splicing platform 11 and the second splicing platform 12 can move relative to each other along a first direction to drive the splicing cloth 14 to wrap the composite section to complete the splicing.

[0130] like Figure 3 As shown, further, at the position to be spliced, a composite section placement area 151 is provided on the splicing cloth 14, and the composite section placement area 151 is located between the splicing front end of the second splicing platform 12 and the first splicing platform 11. The composite section is placed in the composite section placement area 151 by the composite section feeding robot, and when the second splicing platform 12 moves toward the first splicing platform 11 along the first direction, the composite section located in the composite section placement area 151 is wrapped by the splicing cloth 14 and rolls.

[0131] Furthermore, the first splicing platform 11 is parallel to the second splicing platform 12. In the splicing position, the second splicing platform 12 is spaced apart relative to the first splicing platform 11 in the first direction. The splicing device also includes a receiving groove 152 extending along a third direction. The receiving groove 152 is located below the composite section placement area 151 along the second direction, and is used to receive the splicing cloth 14 located in the composite section placement area 151, wherein the third direction is parallel to the second splicing platform 12 and perpendicular to the first direction.

[0132] Furthermore, the receiving groove 152 can be matched to accommodate a composite filter rod or a smoking segment with a diameter ranging from 5.4 mm to 7.7 mm.

[0133] Furthermore, the first splicing platform 11 is parallel to the second splicing platform 12. In the splicing position, the splicing device also includes a first centering rod 21 and a second centering rod 22 arranged relatively along a third direction. The third direction is parallel to the second splicing platform 12 and perpendicular to the first direction. The first centering rod 21 and the second centering rod 22 are located in the composite section placement area and are pressed on the splicing cloth 14 along the third direction. The composite section is located between the first centering rod 21 and the second centering rod 22 along the third direction. The first centering rod 21 and the second centering rod 22 are used to close the composite section in the third direction to avoid gaps between the composite sections.

[0134] like Figure 4As shown, in one embodiment, the splicing device further includes a centering manipulator 2, which includes a first centering rod 21 and a second centering rod 22 arranged relatively along a third direction. The centering manipulator 2 also includes a centering X-axis motor 23, a lifting shaft 24, a servo module 25, a splicing centering motor 231, a synchronous belt mechanism 27, a centering cylinder 28, a first centering rod rotating seat 29, and a second centering rod rotating seat 20. Among them, the first centering rod rotating seat 29 and the second centering rod rotating seat 20 are respectively distributed on both sides along the third direction, and are used to fix the first centering rod 21 and the second centering rod 22. The function of the synchronous belt mechanism 27 is to prevent the height difference caused by the asynchronous rise of the two centering rods. The function of the centering cylinder 28 is to prevent the second centering rod 22 from colliding with the splicing unit 1 during the process of lifting and lowering in the retracted state. In the extended state, the second centering rod 22 can be inserted into the groove in the splicing unit 1 as the reference end of the splicing length of the composite section.

[0135] When the composite segment loading robot places the composite segment into the receiving groove 152 or the composite segment placement area 151 of the splicing unit 1, the splicing centering motor 231 starts to operate, driving the servo module 25 to drive the lifting shaft 24 to descend, so that the first centering rod 21 and the second centering rod 22 enter the receiving groove 152 in the splicing unit 1. At the same time, the centering X-axis motor 23 drives the first centering rod 21 to start rotating. The distance between the first centering rod 21 and the second centering rod 22 is the length of the composite segment after the splicing is completed.

[0136] In one embodiment, when the composite section is closed in place, the centering robot 2 withdraws from the receiving groove 152, the rubbing centering motor 231 rotates in the opposite direction, the lifting shaft 24 rises under the drive of the servo module 25, and the first centering rod 21 and the second centering rod 22 withdraw from the receiving groove 152, completing the loading of the composite section.

[0137] In another embodiment, the first centering rod 21 and the second centering rod 22 of the centering robot 2 move forward a certain distance along with the composite section driven by the splicing cloth, and then the centering robot 2 withdraws from the receiving groove 152, the splicing centering motor 231 rotates in the opposite direction, and the lifting shaft 24 rises driven by the servo module 25, and the first centering rod 21 and the second centering rod 22 withdraw from the receiving groove 152 to complete the loading of the composite section.

[0138] In other embodiments, the first centering rod and the second centering rod can also be driven to actively rotate, and the rotation speed is the same as the moving speed of the splicing cloth. In this way, when splicing, the tangential speed of the position where the first centering rod and the second centering rod contact the splicing cloth is the same as the moving speed of the splicing cloth. In this way, no relative displacement occurs between the first centering rod and the second centering rod and the splicing cloth, and the splicing cloth is not prone to wrinkles.

[0139] Furthermore, the spacing between the first centering rod 21 and the second centering rod 22 in the third direction is adjustable. The spacing between the first centering rod 21 and the second centering rod 22 can be adjusted by moving the first centering rod 21 and / or the second centering rod 22 along the third direction, or by adjusting the length of the first centering rod 21 and / or the second centering rod 22 to adjust the spacing.

[0140] Furthermore, the first centering rod 21 and the second centering rod 22 can be moved into and out of the position to be spliced.

[0141] Furthermore, the positions of the first centering rod 21 and the second centering rod 22 in the second direction are adjustable. When the second direction is the vertical direction, the servo module 25 drives the lifting shaft 24 to rise or fall, thereby adjusting the positions of the first centering rod 21 and the second centering rod 22 in the second direction.

[0142] In the above embodiments, the first splicing platform 11 has a first front end 111 and a first rear end 112 opposite to each other along a first direction, the first rear end 112 is farther away from the second splicing platform 12 along the first direction than the first front end 111, the second splicing platform 12 has a second front end 123 and a second rear end 124 opposite to each other along the first direction, the second rear end 124 is farther away from the first splicing platform 11 along the first direction than the second front end 123, the reel 13 is located at the second rear end 124, and one end of the splicing cloth 14 is fixed to the first rear end 112.

[0143] Furthermore, the first rear end of the first splicing platform 11 has a slope 16, and the spliced ​​composite section slides down through the slope 16, which facilitates the collection of the spliced ​​composite section.

[0144] Furthermore, a pressing block 17 is provided at the first rear end for fixing one end of the splicing cloth 14 close to the first rear end. When the reel 13 is tightened, the pressing block 17 fixes the splicing cloth 14, and the tension of the splicing cloth 14 can be increased. On the contrary, when the reel 13 is appropriately relaxed, the pressing block 17 fixes one end of the splicing cloth 14, and the tension of the splicing cloth 14 can be reduced. The splicing of composite sections with different diameters can be adaptively adjusted in the above manner.

[0145] Furthermore, a negative pressure port 18 is provided on the first splicing platform 11 for adsorbing the tipping paper. The tipping paper is adsorbed on the first splicing platform 11 by the negative pressure of the airflow, so that the tipping paper will not be displaced during the gluing and splicing process, thereby avoiding the problem of deviation in the gluing position and the inability of the tipping paper to accurately wrap the composite section.

[0146] Furthermore, the first splicing platform 11 is also provided with a heating module 101 for adjusting the temperature of the splicing unit 1 .

[0147] Furthermore, the negative pressure port 18 is a hole-like structure. The negative pressure port 18 can be a plurality of hole-like structures distributed at the apex and the center of the tipping paper. The negative pressure port 18 can also be a plurality of rows of hole-like structures arranged at intervals, which are used to firmly absorb the tipping paper.

[0148] In one embodiment, the spacing between the second splicing platform 12 and the first splicing platform 11 in the second direction is within a set range so as to accommodate the composite segment. The spacing between the second splicing platform 12 and the first splicing platform 11 in the second direction can be set large enough so as to cover the diameters of all composite segments. When the second direction is a vertical direction, for example, the second splicing platform 12 is spatially positioned 10.2 mm higher than the first splicing platform 11, and is used to splice composite segments with a diameter range of 5.4-7.7 mm. The second splicing platform 12 and the first splicing platform 11 have sufficient spacing in the second direction to be applicable to the splicing of composite segments of different diameters. Furthermore, the splicing of filter rods of different diameters can also be better adapted by adjusting the tension of the splicing cloth. Exemplarily, when the diameter of the composite segment changes, fine-tuning of the adaptable diameter range is achieved by adjusting the tension of the splicing cloth.

[0149] In the above embodiments, the distance between the second splicing platform 12 and the first splicing platform 11 in the second direction is adjustable. The height difference between the second splicing platform 12 and the first splicing platform 11 can be adjusted according to actual needs to match filter rods with more different diameters.

[0150] In one embodiment, the splicing device further includes a reel driving member 131, which is used to drive the reel to actively reel in or unwind the splicing cloth 14. The reel driving member 131 can be a motor, and the splicing cloth 14 is tightened under the drive of the motor.

[0151] In another embodiment, the splicing cloth 14 can be tightened without a motor drive during the splicing process, and can be tightened passively under the pull of the second platform 12 .

[0152] Furthermore, there are multiple splicing units 1, which are evenly arranged at intervals along the circumference of the entire splicing device, and multiple splicing units are operated simultaneously to improve the efficiency of feeding, gluing and splicing.

[0153] Furthermore, if Figure 5As shown, the splicing device 1 has a plurality of stations 3, which are sequentially provided with a composite section loading station 31, a tipping paper loading station 32, a gluing station 33 and a splicing forming station 34 along the circumferential direction. The composite section loading station 31 is used to place the composite section on the splicing cloth, the tipping paper loading station 32 is used to place the tipping paper on the first splicing platform, the gluing station 33 is used to gluing the tipping paper, and the splicing forming station 34 is used to splice the composite section with the tipping paper. The number of stations 3 is the same as the number of splicing units 1, and the arrangement position of the stations 3 corresponds to the arrangement position of the splicing units 1. The plurality of splicing units 1 can rotate along the circumferential direction at a set rotation angle, and the splicing unit 1 can transfer from the station 3 of the previous step to the station 3 of the next step with each rotation.

[0154] Specifically, at the composite segment loading station 31, the splicing cloth 14 fits the receiving groove 152 under the action of the centering robot 2, and is used to receive the composite segment transferred by the composite segment loading robot (not shown). The centering robot 2 is located at both ends of the composite segment, and according to the designed length of the composite segment, several composite segments that have been assembled but not spliced ​​are gathered together to prevent gaps from forming between the composite segments. After receiving the composite segment, the splicing translation motor 191 drives the splicing roller 122 and the splicing cloth 14 to move forward to wrap the composite segment to be spliced.

[0155] When the splicing unit 1 rotates to the tipping paper feeding station 32, the air duct connection sleeve 41 is connected to negative pressure, and the negative pressure passes through the pipeline and the negative pressure port 18 on the splicing mounting base plate 10 to receive the tipping paper delivered by the plugging paper fixed-length cutting and feeding unit and firmly adsorb it. The plugging paper fixed-length cutting and feeding unit can cut the plugging paper into a preset appropriate length, and the width of the plugging paper is designed according to the circumference of the filter rod.

[0156] When the splicing unit 1 rotates to the gluing station 33, the automatic gluing unit automatically completes the quantitative gluing of the forming paper. The automatic gluing unit glues part or all of the forming paper according to the design requirements to ensure that the filter rod has a firm overlap after splicing and the internal base rod does not move.

[0157] When the splicing unit 1 rotates to the splicing forming station 34, the splicing translation motor 191 drives the second splicing platform 12 to move along the first direction toward the first splicing platform 11, driving the splicing cloth to wrap the composite section and move forward. During the movement, the glue-sprayed tipping paper and the composite section are automatically spliced ​​to complete the splicing and forming of the composite filter rod.

[0158] This process is repeated repeatedly to achieve the twisting and forming of the composite filter rod.

[0159] Furthermore, there are 4 workstations, namely the composite section loading station 31, the tipping paper loading station 32, the gluing station 33 and the splicing and forming station 34, which are arranged at intervals of 90 degrees along the circumference, and there are 4 splicing units, which are arranged at intervals of 90 degrees along the circumference. Each rotation of the splicing unit 1 can complete a complete splicing process.

[0160] In one embodiment, there can be 8 splicing stations, and the corresponding number of splicing units 1 is also 8. They correspond to the composite section loading station 31, the tipping paper loading station 32, the gluing station 33, and the splicing forming station 34, with 2 stations each. Starting from the starting station, the order of a circle can be "31-32-33-34-31-32-33-34", or "31-31-32-32-33-33-34-34". In the former, the splicing unit 1 rotates 45 degrees each time, and completes a complete splicing process every 180 degrees. In the latter, the splicing unit 1 rotates 90 degrees each time, and completes a complete splicing process every 360 degrees.

[0161] In another embodiment, the number of splicing stations may be 12 or 16 or 20. Considering various aspects such as the splicing process efficiency and the space occupied by the device, the number of splicing stations is preferably 4, namely the composite section loading station 31, the tipping paper loading station 32, the gluing station 33 and the splicing forming station 34.

[0162] In the above embodiments, the splicing unit 1 is composed of a splicing translation motor 191, a splicing cloth rolling motor 192, a splicing mounting seat plate 10, a reel 13, a movable plate 121, a splicing roller 122, a pressing block 17, and also includes a negative pressure sealing plate 181 and a screw driving block 125.

[0163] The negative pressure sealing plate 181 is used to seal the internal passage of the negative pressure pipeline to ensure that the negative pressure airflow only flows in from the negative pressure port 18, thereby ensuring the adsorption effect of the tipping paper and avoiding air leakage.

[0164] After turning away from the gluing station, the splicing translation motor 191 starts to operate, and the lead screw nut drives the lead screw push block 125 to move, so that the moving plate 121 and the splicing roller 122 move together toward the first splicing platform, and the reel 13 unwinds. As the moving plate 121 and the splicing roller 122 move, the splicing cloth on the first splicing platform covers the splicing cloth on the first splicing platform and moves for splicing. After that, the splicing cloth rolling motor 192 starts to operate, and the reel 13 starts to reel and push the splicing cloth 14, completing the splicing and pushing the spliced ​​composite section to the downstream.

[0165] like Figure 6As shown, the splicing device further includes a rotating shaft 42 and a rotating disk 43. The splicing unit 1 is disposed on the rotating disk 43. The rotating shaft 42 rotates to drive the rotating disk 43 to rotate, thereby driving the splicing unit 1 to rotate around the rotating shaft 42 in the circumferential direction.

[0166] Furthermore, the rotating shaft 42 is a hollow structure, which is respectively connected to the negative pressure port 18 and the negative pressure device 45. A negative pressure pipeline is provided inside the splicing unit 1, which is connected to the rotating shaft 42, the negative pressure port 18 and the negative pressure device 45. It is used to stably provide negative pressure to the negative pressure port 18 to absorb the tipping paper.

[0167] Furthermore, the splicing device also includes a first slip ring 441 and a second slip ring 442, the first slip ring 441 is used to fix the moving circuit, and the second slip ring 442 is used to fix the stator circuit, wherein the moving circuit rotates with the rotation of the rotating shaft, and the stator circuit does not rotate with the rotation of the rotating shaft, and is used to separate the moving circuit from the stator circuit to prevent the circuits from being entangled when the splicing device is running.

[0168] Furthermore, the first slip ring 441 is fixed inside the rotating shaft 42, and the second slip ring sleeve 442 is connected to the outside of the rotating shaft 42. The moving circuit inside the rotating shaft 42 rotates with the rotation of the rotating shaft 42, and the stator circuit sleeved outside the rotating shaft 42 does not rotate with the rotating shaft 42.

[0169] like Figure 7 As shown, the splicing device consists of a turntable rotating motor 461, a turntable rotating motor mounting base 462, a rotating disk 43, a rotating shaft 42, an air blowing transition pipe 471, a splicing air duct 472, a splicing station bearing sleeve 481, a slip ring 44, an air duct connecting sleeve 482, a splicing rotating bearing spacer sleeve 483 and a splicing rotating bearing clamping cover 484.

[0170] The rotating motor 461 drives the synchronous belt to rotate, so that the rotating shaft 42 rotates, and the rotating disk 43 rotates accordingly. The lower part of the rotating shaft 42 is connected with the air duct connecting sleeve 482 and the air duct, which passes through the air duct, the air duct 472 and the blowing transition pipe 471, and finally leads to the splicing unit 1, forming a complete negative pressure channel.

[0171] refer to Figure 9-Figure 24The embodiment of the utility model also discloses a splicing method, which uses the above-mentioned splicing device to splice the composite segment in the aerosol generating product, including the following steps: placing the composite segment on the splicing cloth 14, and placing the tipping paper on the first splicing platform 11; the second splicing platform 12 is staggered or spaced relative to the first splicing platform 11 in the first direction, and is higher than the first splicing platform 11 in the second direction, and the first splicing platform 11 and the second splicing platform 12 are moved in a relatively close direction along the first direction, driving the splicing cloth 14 to wrap the composite segment and move, and then the splicing cloth 14 drives the composite segment to roll toward the tipping paper to complete the splicing.

[0172] By adopting the above technical solution, composite sections with different diameters can be spliced, thereby improving the usable range of the device.

[0173] Fig. 9 for Fig.10 The AA line cross-sectional view only shows part of the structure of the splicing device, including the splicing unit. Similarly, Fig.11 for Fig.12 AA line section view, Fig.13 for Fig.14 AA line section view, Fig.15 for Fig.16 AA line section view, Fig.17 for Fig.18 AA line section view, Fig.19 for Fig. 20 AA line section view, Fig.21 for Fig. 22 AA line section view, Fig.23 for Fig.24 AA line section view. Figure 9-Figure 24 The figure shows the whole dynamic change of the splicing device from the state of waiting for splicing to the state of splicing and the state of completing splicing. Figure 9-14 , showing that the splicing unit is in the waiting position for splicing, Figure 15-18 The schematic diagram of the changing state of splicing is shown. Figure 19-20 It shows the schematic diagram of the state of the splicing unit rotating to the tipping paper loading station. Figure 21-22 It shows the schematic diagram of the state where the splicing unit rotates to the gluing station. Figure 23-Figure 24 The schematic diagram of the state of the splicing unit rotating to the splicing forming station is shown. The following takes one of the multiple splicing units in the splicing device as an example, that is, the first splicing unit 04 described below, to introduce its state during the entire splicing process.

[0174] Fig. 9 is a schematic diagram of the initial state of the splicing unit. Fig.10 Schematic diagram of the initial state of the splicing device. Fig. 9 for Fig.10The AA line cross-sectional view only shows part of the structure of the splicing device, including the splicing unit. The splicing device and the splicing unit are in an initial state before the splicing starts, and the splicing unit is in a waiting position for splicing. The first splicing platform 11 and the second splicing platform 12 are spaced apart along the first direction, and a receiving groove is provided at the interval, and the splicing cloth 14 is continuously laid flat on the first splicing platform 11. The first splicing platform 11 is lower than the second splicing platform 12 in the second direction. The splicing cloth is in a tensioned state, and the first centering rod 21 and the second centering rod 22 are both in a state away from the splicing platform to prevent the splicing platform from colliding with the first centering rod 21 and the second centering rod 22 when rotating, thereby affecting the stable operation of the splicing device. The first splicing unit 04 is in the compound section loading station 31 until the centering rod is completely pulled out.

[0175] Fig.11 This is a schematic diagram of the centering rod of the splicing unit in the downward pressing state. Fig.12 This is a schematic diagram of the centering rod of the splicing device being pressed down. Fig.11 for Fig.12 The AA line cross-sectional view only shows part of the structure of the splicing device, including the splicing unit. After the initial state, the splicing device and the splicing unit enter a state where the centering rod is pressed down. The first centering rod 21 and the second centering rod 22 are first extended, then pressed down, and fall into the receiving groove 152. At this time, the second centering rod 22 is pushed by the cylinder as the reference end. The first centering rod 21 is controlled by the servo module and can be controlled by the program to any displacement amount, as a moving end. The distance between the first centering rod 21 and the second centering rod 22 is the total length of the composite section 05. By adjusting the displacement of the first centering rod 21, composite sections 05 of different lengths can be matched. The splicing cloth 14 is pressed into the groove by the downward force of the two centering rods.

[0176] Fig.13 This is a schematic diagram of the placement of the composite section state of the splicing unit. Fig.14 This is a schematic diagram of the placement of the composite section of the splicing device. Fig.13 for Fig.14 The AA line cross-sectional view only shows part of the structure of the splicing device, including the splicing unit. After the centering rod is pressed down, the splicing device and the splicing unit enter the composite segment placement state. After the composite segment loading robot places the composite segment into the receiving groove 152, the second centering rod 22 driven by the cylinder serves as the reference end, and the first centering rod driven by the motor serves as the moving end, pushing the composite segment to contact the reference end, that is, the second centering rod 22. The composite segment 05 is composed of multiple small segments, and the purpose of the first centering rod 21 pushing is to arrange the composite segments 05 closely and reduce the gap between the composite segments 05.

[0177] Fig.15 Schematic diagram of the splicing movement state of the splicing unit. Fig.16 It is a schematic diagram of the splicing movement state of the splicing device. Fig.15 for Fig.16 The AA line cross-sectional view only shows part of the structure of the splicing device, including the splicing unit. After the composite segment is placed, the splicing device and the splicing unit enter the splicing movement state. The second splicing platform 12 moves along the direction C in the figure, covering a part of the first splicing platform 11, further allowing the splicing cloth 14 to cover the top of the composite segment placement area, wrapping more of the composite segment 05. The splicing movement in this state and then the centering rod is pulled out is to prevent the composite segment 05 from flying out of the groove after the centering rod is pulled out.

[0178] Fig.17 This is a schematic diagram of the centering rod of the splicing unit being pulled out. Fig.18 This is a schematic diagram of the centering rod of the splicing device being pulled out. Fig.17 for Fig.18 The AA line cross-sectional view only shows part of the structure of the splicing device, including the splicing unit. After the splicing moving state, the splicing device and the splicing unit enter the centering rod withdrawal state. At this time, the first centering rod 21 and the second centering rod 22 retract along the third direction and are raised along the second direction, thereby moving away from the groove to prevent collision with the splicing unit. The centering rod presses the splicing cloth down into the groove, so when the centering rod is withdrawn, the splicing cloth is re-tensioned and tightly fitted on the composite section. The first splicing unit 04 is at the composite section loading station 31.

[0179] Fig.19 This is a schematic diagram of the filter paper placement state of the splicing unit. Fig. 20 This is a schematic diagram of the filter paper placement state of the splicing device. Fig.19 for Fig. 20 The AA line cross-sectional view only shows part of the structure of the splicing device, including the splicing unit. After the centering rod is pulled out, the splicing device and the splicing unit enter the filter paper placement state, and the first splicing unit 04 rotates from the composite section loading station 31 to the tipping paper loading station 32, and absorbs the tipping paper 06 through the negative pressure port 18.

[0180] Fig.21 This is a schematic diagram of the gluing state of the splicing unit. Fig. 22 This is a schematic diagram of the gluing state of the splicing device. Fig.21 for Fig. 22 The AA line cross-sectional view only shows part of the structure of the splicing device, including the splicing unit. When the filter paper placement state ends, the splicing device and the splicing unit enter the gluing state. The splicing unit rotates from the tipping paper feeding station 32 to the gluing station 33, and the tipping paper 06 is glued by the automatic gluing mechanism.

[0181] Fig.23 It is a schematic diagram of the splicing forming state of the splicing unit. Fig.24 It is a schematic diagram of the splicing forming state of the splicing device. Fig.23 for Fig.24 The AA line cross-sectional view only shows part of the structure of the splicing device, including the splicing unit. When the gluing state is completed, the splicing device and the splicing unit enter the splicing forming state, and the second splicing platform 12 moves along the C direction to splice the tipping paper 06 on the outer surface of the composite section 05 to form a formed filter rod or a formed cigarette, and then continues to move along the C direction to drive the filter rod to the slope to complete the discharge.

[0182] During the splicing process, the second splicing platform 12 moves toward the first splicing platform, driving the splicing cloth 14 to wrap the composite section, so that the composite section rolls toward the tipping paper, thereby completing the process of wrapping the composite section with the tipping paper.

[0183] Furthermore, a composite section placement area 151 is provided on the splicing cloth 14, and the composite section placement area 151 is located between the splicing front end of the second splicing platform 12 and the first splicing platform 11, and the first splicing platform 11 is parallel to the second splicing platform 12. The splicing device also includes a first centering rod 21 and a second centering rod 22. The method includes: at the splicing position, the first centering rod 21 and the second centering rod 22 are arranged relatively along the third direction and are located in the composite section placement area 151, and are pressed on the splicing cloth along the third direction, and the composite section is placed between the first centering rod 21 and the second centering rod 22 along the third direction, and the ends of the first centering rod 21 and the second centering rod 22 abut against the composite section, and the composite section is closed, wherein the third direction is parallel to the second splicing platform and perpendicular to the first direction. By controlling the first centering rod 21 and the second centering rod 22 to close the composite section, it is avoided that multiple composite sections directly generate gaps.

[0184] Further, the spacing between the first centering rod 21 and the second centering rod 22 in the third direction is adjusted to match the length of the composite section. The first centering rod 21 and the second centering rod 22 can be withdrawn from the splicing cloth 14. The withdrawal can be carried out by raising the height of the first centering rod 21 and the second centering rod 22, or by increasing the spacing between the first centering rod 21 and the second centering rod 22.

[0185] Furthermore, the distance between the second kneading platform 12 and the first kneading platform 11 in the second direction is adjusted to match the diameter of the composite section.

[0186] Optionally, after the splicing is completed, the splicing cloth is rolled up to make the splicing cloth 14 tensioned, and the splicing cloth 14 pushes out the spliced ​​composite segment through the tensioning effect. The tension of the splicing cloth 14 is used to squeeze and push out the spliced ​​composite segment from the first rear end 112, so as to facilitate the collection of the composite segment.

[0187] Furthermore, there are multiple splicing units 1, which are evenly arranged at intervals along the circumferential direction. The splicing device has multiple stations 3, which are sequentially arranged along the circumferential direction with a composite section loading station 31, a tipping paper loading station 32, a gluing station 33 and a splicing forming station 34. The composite section loading station 31 is used to place the composite section on the splicing cloth, the tipping paper loading station 32 is used to place the tipping paper on the first splicing platform, the gluing station 33 is used to gluing the tipping paper, and the splicing forming station 34 is used to splice the composite section with the tipping paper. The number of stations 3 is the same as the number of splicing units 1, and the arrangement position of the stations 3 corresponds to the arrangement position of the splicing units 1. The splicing method comprises: driving multiple splicing units 1 to rotate multiple times at a set rotation angle along the circumferential direction, and each time the splicing unit 1 rotates, it can move from the station 3 of the previous step to the station 3 of the next step.
