Description

Technical Field

[0001] This utility model relates to the field of tobacco equipment technology, and in particular to a mouth-held cigarette filling packaging device. Background Technology

[0002] Oral cigarettes are smokeless tobacco products, referring to a new type of tobacco product with nicotine as the main active ingredient, packaged in non-woven fabric pouches for oral consumption. Existing oral cigarette packaging equipment typically consists of a feeding mechanism, a metering mechanism, a filling mechanism, and a sealing mechanism, mostly with a semi-open or open structure. The non-woven fabric is fed manually or by simple rollers. After being metered, the tobacco is directly filled into the non-woven fabric pouch, and then sealed and cut to form the oral cigarette product. The metering method of existing oral cigarette packaging equipment mostly uses a metering box to hold a fixed weight of tobacco material, and then fills the non-woven fabric outer shell with the fixed weight of tobacco material.

[0003] However, existing metering methods have poor compatibility with material humidity. When the material is wet, the metering accuracy of the metering box is poor, and if the weight of the packaged material needs to be changed, the size of the metering box must be changed, which is time-consuming and labor-intensive. Therefore, there is an urgent need to propose a solution to solve this problem. Utility Model Content

[0019] This utility model proposes a non-woven fabric filling and packaging device, comprising a fabric supply device, a metering and filling device, a packaging device, and a rejection device.

The filling nozzles also have air blowing holes for connecting to a compressed air source. Understandably, by setting up a worm gear that meshes with multiple worm wheels, when the worm gear rotates, the multiple worm wheels rotate simultaneously. These worm wheels drive their respective mixing mechanisms to agitate the material in the hopper, thoroughly homogenizing and mixing the material, preventing stratification and clumping, thus ensuring that even wet material remains loose, facilitating subsequent processes. Furthermore, by setting up multiple metering tubes, each containing a screw, when the metering drive unit drives the multiple screws to rotate, the material enters the metering tube with the rotation of the screws, and the material in the screw thread gaps is gradually discharged from the filling nozzle. Precise control of the metering drive speed controls the screw speed, thereby quantitatively pushing the material to the filling nozzle. A sealed metering chamber is formed between the screw and the inner wall of the metering tube, preventing material leakage and ensuring that the weight and volume of each portion of material are consistent. The weight and volume of each portion of material can be adjusted as needed by changing the number of rotations of the metering drive. In addition, compressed air is introduced through the air blowing port to clean the material residue in the filling nozzle, preventing material from adhering and clogging the nozzle, and also helping the material to completely and thoroughly enter the filling tube, avoiding waste and contamination.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] This embodiment proposes a mouth-held cigarette filling packaging device to solve the problems of inaccurate unit material measurement and inconvenience in adjusting the unit material weight in existing packaging equipment.

[0036] like Figures 1-3 As shown, a nonwoven fabric filling and packaging device includes a fabric supply device 2, a metering and filling device 1, a packaging device 3, and a rejection device 4. The fabric supply device 2 can provide nonwoven fabric strips to the packaging device 3. The metering and filling device 1 can provide metered material to the packaging device 3. The packaging device 3 can shape the nonwoven fabric strips and fill the shaped nonwoven fabric strips with the metered material to form nonwoven fabric products. The rejection device 4 can detect the nonwoven fabric products and reject defective products.

[0037] The metering and filling device 1 includes a first mounting frame 11, on which a hopper 12 is mounted. A worm gear 13 is rotatably mounted on the first mounting frame 11, and multiple worm wheels 14 are spaced apart on the first mounting frame 11. All the worm wheels 14 mesh with the worm gear 13. Multiple stirring mechanisms are provided in the hopper 12, and each stirring mechanism corresponds to one of the multiple worm wheels 14. The worm wheels 14 are connected to the corresponding stirring mechanisms in a driving connection, and the stirring mechanisms can stir the material in the hopper 12.

[0038] The metering and filling device 1 also includes a metering drive 18 and multiple metering tubes 17. The inlets of the multiple metering tubes 17 are all connected to the hopper 12. Multiple screws 16 are rotatably arranged in the hopper 12. The multiple screws 16 are inserted into the multiple metering tubes 17 one by one. The screws 16 are connected to the metering drive 18 for transmission. The metering drive 18 can drive the screws 16 to rotate. The outlets of the multiple metering tubes 17 are all equipped with filling nozzles 101. The filling nozzles 101 are connected to the filling tube 33 of the packaging device 3. The filling nozzles 101 are also provided with air blowing holes 1011, which are used to connect to a compressed air source.

[0039] Understandably, by setting a worm gear 13, which meshes with multiple worm wheels 14, when the worm gear 13 rotates, the multiple worm wheels 14 rotate simultaneously. The multiple worm wheels 14 drive their respective corresponding stirring mechanisms to agitate in the hopper 12, thoroughly homogenizing and mixing the material, preventing material stratification and clumping, thus ensuring that the wet material remains in a loose state, which is beneficial for subsequent processes. Furthermore, by setting multiple metering tubes 17, each metering tube 17 is equipped with a screw 16. When the metering drive 18 drives the multiple screws 16 to rotate, the material enters the metering tube 17 as the screws 16 rotate, and the material in the thread gaps of the screws 16 is gradually discharged from the filling nozzle 101. The rotation speed of the metering drive 18 is precisely controlled, thereby controlling the rotation speed of the screw 16, which in turn pushes the material quantitatively to the filling nozzle 101. The screw 16 and the inner wall of the metering tube 17 form a sealed metering cavity, which not only prevents material leakage but also ensures that the weight and volume of each portion of material are consistent. At the same time, the weight and volume of each portion of material can be changed as needed by changing the number of rotations of the metering drive 18. In addition, compressed air is introduced through the air blowing hole 1011, which can clean the material remaining in the filling nozzle 101, prevent the material from adhering and clogging the filling nozzle 101, and at the same time help the material to completely and thoroughly enter the filling tube 33, avoiding waste and contamination.

[0040] For example, the metering drive 18 can be set as one, and multiple screws 16 can be drivenly connected to the metering drive 18. The structure is simple and easy to operate. Alternatively, multiple metering drive 18 can be set, with multiple metering drive 18 corresponding to multiple screws 16 one by one, and the metering drive 18 is drivenly connected to the corresponding screw 16. This enables individual control of the discharge weight and volume of each filling nozzle 101, improving the functional diversity and operability of the oral cigarette filling packaging equipment.

[0041] As another example, the metering drive 18 is a servo motor to improve operational flexibility and reliability. Of course, in other embodiments, the metering drive 18 can also be other types of drive components, which can be set as needed according to actual conditions. This embodiment does not impose too many restrictions.

[0042] It is worth noting that the compressed air source can be a gas compressor, fan, or high-pressure gas tank in the workshop, and can be selected as needed according to the actual situation on site. This is not the focus of this embodiment and will not be elaborated here.

[0043] In some optional embodiments, the first mounting frame 11 is rotatably equipped with multiple mounting shafts, and multiple worm gears 14 are correspondingly mounted on the multiple mounting shafts. A drive gear is mounted on each mounting shaft. Multiple stirring mechanisms are correspondingly arranged with the multiple mounting shafts. Each stirring mechanism includes a driven gear, a connecting rod assembly, and a stirring rod assembly 15. The driven gear meshes with the drive gear. The stirring rod assembly 15 is movably disposed in the hopper 12 and is drivenly connected to the connecting rod assembly, which in turn is drivenly connected to the driven gear. With this arrangement, when the worm gear 13 rotates, the corresponding worm gears 14 mounted on the multiple mounting shafts rotate, driving the connecting rod assembly and subsequently the stirring rod assembly 15 to swing, thereby agitating the material in the hopper 12 and improving the structural rationality of the oral cigarette filling packaging equipment.

[0044] For example, the stirring rod assembly 15 includes two intersecting stirring rods. The connecting rod assembly can convert the rotation of the driven gear into the relative oscillation of the two stirring rods, thereby stirring the material in the hopper 12. It is worth noting that the structure and cooperation relationship of the stirring mechanism, i.e., the driven gear, the connecting rod assembly, and the stirring rod assembly 15, are all prior art, and this embodiment does not impose too many limitations.

[0045] For example, the first mounting frame 11 has a mounting chamber 102, and all mounting shafts are installed inside the mounting chamber 102. The material hopper 12 is located at the lower end of the mounting chamber 102, and the bottom wall of the mounting chamber 102 forms the top wall of the material hopper 12. With this arrangement, the structure of the drive stirring rod assembly 15 is located in the mounting chamber 102 outside the material hopper 12. On the one hand, this protects the equipment in the mounting chamber 102 from material corrosion, and on the other hand, it increases the space for the material hopper 12 to hold materials, thereby improving the structural rationality of the oral cigarette filling packaging equipment.

[0046] In some optional embodiments, the metering and filling device 1 further includes a stirring drive 19 and a metering central processing unit. The stirring drive 19 is connected to the worm gear 13 and can drive the worm gear 13 to rotate. Both the stirring drive 19 and the metering drive 18 are electrically connected to the metering central processing unit. Understandably, by setting the metering central processing unit, the metering central processing unit can control the number of rotations of the metering drive 18 according to the set material volume and weight, and can also determine the running time of the stirring drive 19 according to the equipment operating status. The degree of automation is high, requiring only settings by the operator, thus improving the operability and functional rationality of the oral cigarette filling and packaging equipment.

[0047] As another example, the worm gear 13 is rotatably mounted on both sides of the mounting chamber 102, and one end of the worm gear 13 extends out of the mounting chamber 102 from the side wall of the mounting chamber 102 and is connected to the stirring drive 19 mounted on the outer wall of the mounting chamber 102 to avoid interference between the stirring drive 19 and the components inside the mounting chamber 102. The stirring drive 19 can be a servo motor to improve start-stop flexibility.

[0048] like Figure 4 As shown, in some optional embodiments, the fabric feeding device 2 includes a second mounting frame 21, on which a feeding drive 22 and an air shaft 23 are provided. The feeding drive 22 is pulsatorically connected to the air shaft 23 and can drive the air shaft 23 to rotate. The air shaft 23 is used to mount the nonwoven fabric roll 100. The second mounting frame 21 is also provided with an adaptive tension assembly, which includes an encoder 24, an adaptive roller 25, a movable rod, and a mounting component 26. The adaptive roller 25 is rotatably mounted on the movable rod, and the end of the movable rod away from the adaptive roller 25 is rotatably mounted on the second mounting frame 21 and pulsatorically connected to the encoder 24. The mounting component 26 has a vertically extending arc-shaped guide groove, and the movable rod has an indicator. The indicator is inserted into the arc-shaped guide groove. An elastic element is connected between the lower end of the mounting component 26 and the indicator. The elastic element has a tendency to position the indicator at the lower end of the arc-shaped guide groove. The second mounting frame 21 is also provided with a roller cutter mechanism 27. The nonwoven fabric extending from the nonwoven fabric roll 100 can abut against the adaptive roller 25 and be clamped in the roller cutter mechanism 27. The roller cutter mechanism 27 can cut the nonwoven fabric into nonwoven fabric strips. The fabric feeding device 2 also includes a feeding central processor. The encoder 24 and the unloading drive 22 are all electrically connected to the feeding central processor.

[0049] Understandably, the feeding drive 22 can drive the air shaft 23 to rotate, thereby causing the nonwoven fabric roll 100 mounted on the air shaft 23 to rotate, so that the nonwoven fabric is continuously fed. The roller cutter mechanism 27 cuts the nonwoven fabric into multiple nonwoven fabric strips for the packaging device 3 to form and process. By setting an adaptive tension component, the nonwoven fabric abuts against the adaptive roller 25. When the nonwoven fabric feeding is slow, the nonwoven fabric pushes the adaptive roller 25, which in turn pushes the movable rod to rotate. The indicator moves upward along the arc-shaped guide groove against the elastic force of the elastic component. The encoder 24 synchronously collects the position signal of the adaptive roller 25. The value of the encoder 24 changes, and the feeding central processor receives the signal. After this change, the control of the feeding drive 22 is accelerated to loosen the nonwoven fabric roll 100, thereby preventing the nonwoven fabric from being torn. When the nonwoven fabric is fed quickly, the indicator is located at the lower end of the arc-shaped guide groove, and the corresponding encoder 24 value is uploaded to the feeding central processor. The feeding central processor controls the speed of the feeding drive 22 to decrease, so that the nonwoven fabric roll 100 is tightened, forming a closed-loop control logic of "material consumption - position feedback - servo replenishment - tension reset". This ensures that the material tension is always maintained in a stable range, avoiding wrinkles caused by over-feeding or breakage caused by under-feeding, and improving the reliability and structural rationality of the oral cigarette filling packaging equipment.

[0050] It is worth noting that the encoder 24, air shaft 23, and feeding central processing unit are all commercially available products, and this embodiment does not impose too many restrictions on their specific structure and principle. The feeding drive can be a servo motor to improve start-stop flexibility and speed control accuracy.

[0051] In some optional embodiments, the second mounting frame 21 is horizontally and movably mounted with an adjusting bracket. The feeding drive 22 and the air shaft 23 are both mounted on the adjusting bracket. The second mounting frame 21 is also equipped with a deviation correction sensor 28 and a deviation correction drive 29. The deviation correction sensor 28 can detect the movement trajectory of the nonwoven fabric, and the driving end of the deviation correction drive 29 can drive the adjusting bracket to move horizontally. Both the deviation correction sensor 28 and the deviation correction drive 29 are electrically connected to the feeding central processor. Understandably, the feeding central processor controls the rotation of the deviation correction drive 29 according to the signal from the deviation correction sensor 28, changes the lateral position of the adjusting bracket in real time, quickly corrects the material deviation problem, ensures the cutting accuracy and the material alignment accuracy of the forming process of the packaging device 3, realizes long-term continuous and stable production without human intervention, effectively improves the consistency and production efficiency of nonwoven fabric formed products, and has strong compatibility with nonwoven fabric materials of different thicknesses and widths.

[0052] For example, the second mounting bracket 21 is horizontally provided with a guide rail, and the adjusting bracket is provided with a guide groove. The guide rail and the guide groove cooperate, allowing the adjusting bracket to move laterally on the guide rail, thereby improving the smoothness and stability of the lateral movement. It is worth mentioning that the correction sensor 28 can be a commercially available product, and this embodiment does not impose too many restrictions on its specific structure.

[0053] For another example, the correction drive 29 is a servo motor. The drive end of the correction drive 29 is connected to a lead screw. The adjustment bracket has a threaded hole. The lead screw is threadedly engaged with the threaded hole on the adjustment bracket. The rotation of the correction drive 29 can move the adjustment bracket relative to the second mounting bracket 21, thereby achieving stable and controllable lateral movement of the adjustment bracket and improving the reliability and structural rationality of the smoke filling and packaging equipment.

[0054] In some optional embodiments, the fabric feeding device 2 further includes a magnetic pressure block 201, which can press the nonwoven fabric against the second mounting frame 21. The magnetic pressure block 201 then presses the end of the nonwoven fabric with a flexible pressing action, preventing the nonwoven fabric from getting messed up during the roll changing process and further improving the stability of the equipment.

[0055] In some optional embodiments, the second mounting frame 21 is also rotatably provided with a plurality of idler rollers 202, which can abut against the nonwoven fabric to further improve the movement stability of the nonwoven fabric.

[0056] The roller cutting mechanism 27 includes a support frame, a cutting roller 271, and a cutting drive component. The support frame is mounted on the second mounting frame 21. The cutting roller 271 is rotatably mounted on the support frame. The cutting drive component is mounted on the support frame and is connected to the cutting roller 271 for transmission. The cutting drive component is electrically connected to the feeding central processor. Under the control of the feeding central processor, the cutting drive component drives the cutting roller 271 to operate, cutting the nonwoven fabric into multiple nonwoven strips for use in the next process. It is worth mentioning that the cutting roller 271 is existing technology, and its specific structure and principle will not be described in detail in this embodiment.

[0057] like Figures 5-6As shown, in some optional embodiments, the packaging device 3 includes a packaging mounting frame 31, a limiting plate 32, multiple filling tubes 33, and a longitudinal sealing drive mechanism 34. The limiting plate 32 and the multiple filling tubes 33 are both mounted on the packaging mounting frame 31, and the limiting plate 32 is located on the upper part of the multiple filling tubes 33. The multiple filling tubes 33 are arranged side by side at intervals. A guide folding mechanism is installed on the limiting plate 32. The guide folding mechanism can fold the non-woven fabric strip into a cylindrical shape and sleeve it on the filling tube 33. Each filling tube 33 has a covering block 35 installed at its inlet end. The covering block 35 has a covering groove, and the filling tube 33 is located in the covering groove. The covering block 35 can adhere and cover the non-woven fabric strip to the outer wall of the filling tube 33. The longitudinal sealing drive mechanism 34 includes a longitudinal sealing hot plate 34. 1. A longitudinal sealing frame 342 and a longitudinal sealing cylinder 343 are mounted on the longitudinal sealing frame 342. The longitudinal sealing frame 342 is movably mounted on the packaging mounting frame 31, and the drive end of the longitudinal sealing cylinder 343 is connected to the packaging mounting frame 31. A longitudinal sealing hot stamping block 341 is mounted on the longitudinal sealing frame 342. The longitudinal sealing cylinder 343 can drive the longitudinal sealing frame 342 to approach or move away from the packaging mounting frame 31, so that the longitudinal sealing hot stamping block 341 abuts or moves away from the cylindrical non-woven fabric strip. A conveying wheel is also rotatably mounted on the packaging mounting frame 31. The conveying wheel can abut against the cylindrical non-woven fabric strip. The rotation of the conveying wheel can transport the cylindrical non-woven fabric strip along the filling pipe 33. The discharge end of the filling pipe 33 can discharge material to fill the cylindrical non-woven fabric strip.

[0058] For example, the longitudinal sealing frame 342 includes a longitudinal sealing fixing plate 3421 and multiple support legs 3422 connected to both ends of the longitudinal sealing fixing plate 3421. The longitudinal sealing hot block 341 and the longitudinal sealing cylinder 343 are both installed on the longitudinal sealing fixing plate 3421. Multiple support leg seats are provided on the packaging mounting frame 31. The multiple support leg seats correspond one-to-one with the multiple support legs 3422. The support leg seats are movably sleeved on the corresponding support legs 3422 to improve the movement stability and smoothness of the longitudinal sealing frame 342.

[0059] As another example, the filling tube 33 has a heat-sealing working surface that faces the longitudinal sealing block. The surface of the heat-sealing working surface is polished and coated with Teflon, which facilitates the efficient transmission of heat-sealing temperature and pressure by the longitudinal sealing block 341 and prevents the non-woven fabric strips from sticking together, thereby improving the reliability of the oral cigarette filling packaging equipment.

[0060] In some optional embodiments, the packaging device 3 further includes a product guide and a horizontal sealing drive mechanism 36. The product guide corresponds one-to-one with the lower ends of multiple filling tubes 33. The product guide can guide the oral cigarette product to the feeding end of the rejection device 4. The horizontal sealing drive mechanism 36 includes a driving wheel 361, a driven wheel, a horizontal sealing linkage assembly, and a horizontal sealing hot plate 362. The driving wheel 361 is connected to a motor drive, and the driven wheel is connected to the driving wheel 361 through a transmission belt. The horizontal sealing linkage assembly includes a reciprocating kit and a connecting rod. A sliding member is slidably disposed on the reciprocating kit. One end of the sliding member is movably connected to the connecting rod, and the end of the connecting rod away from the sliding member is movably connected to the wheel edge of the driven wheel. The end of the sliding member away from the connecting rod is connected to the horizontal sealing hot plate 362. When the driven wheel rotates, the sliding member reciprocates on the reciprocating kit, thereby causing the horizontal sealing hot plate 362 to abut against or move away from the cylindrical non-woven fabric strip, and perform horizontal heat sealing on it.

[0061] In some optional embodiments, the product guide and the horizontal sealing drive mechanism 36 are both mounted on the lifting frame 37. The lifting frame 37 is slidably mounted on the packaging mounting frame 31. A lifting servo motor 38 is provided on the packaging mounting frame 31. The shaft of the lifting servo motor 38 is vertically connected to a ball screw. The lifting frame 37 has a threaded hole, and the ball screw cooperates with the threaded hole. The rotation of the lifting servo motor 38 can drive the lifting frame 37 to rise and fall. Further, the fixed seat 39 is mounted on the packaging frame. The guide rods 301 symmetrically arranged on both sides of the lifting frame 37 are slidably sleeved on the two fixed seats 39, thereby providing high-precision guidance and support for the lifting frame 37, effectively suppressing sway and vibration during the movement, and ensuring the repeatability accuracy of the heat sealing position. A cutter 302 is provided on the horizontal sealing hot plate 362. A guide groove is provided on the opposite side of the cutter 302. The guide groove is used to guide the cigarette-containing product to the rejection device 4. After the transverse heat sealing is completed, the downward cylinder performs a precise pull-down action, pulling down the sealed cylindrical non-woven fabric strip by the length of a cigarette-containing product, reserving a workstation for the next round of heat sealing and cutting, thus achieving continuous automated production. The up-and-down movement of the cutter 302 is only used for fine-tuning the cutting position to adapt to the cutting requirements of different packaging bag sizes. Once the position of the cutter 302 is calibrated by the servo drive click, the corresponding servo drive motor immediately locks itself and is no longer linked with the overall packaging device 3, avoiding positional deviation during the cutting process and ensuring the consistency of the packaging bag cutting size and the flatness of the cut.

[0062] like Figure 7As shown, in some optional embodiments, the rejection device 4 includes a third mounting frame 41, a receiving mechanism 42, and a sorting mechanism 43. The third mounting frame 41 is equipped with a defective product outflow conveyor belt 44 and a good product outflow conveyor belt 45. The receiving mechanism 42 includes a receiving component 421, a weight sensor, and a visual inspection sensor 46. The receiving component 421 has multiple receiving slots 4211, each of which is used to hold packaged cigarette products. The weight sensor is located at the lower end of the receiving component 421 and is used to detect the weight of the cigarette products in each receiving slot 4211. The visual inspection sensor 46 is used to detect the shape of the cigarette products in each receiving slot 4211. The sorting mechanism 43 is used to place the cigarette products in the receiving slots 4211 onto the defective product outflow conveyor belt 44 or the good product outflow conveyor belt 45. Understandably, the guide trough directs the cigarette products into the receiving trough 4211. A weight sensor acquires the weight of the cigarette products in each receiving trough 4211. If a trough is overweight or underweight, the cigarette products in that trough are directed to the defective product outflow conveyor 44. If they are acceptable, they are directed to the mold on the good product outflow conveyor 45. A visual inspection sensor 46 detects whether the cigarette products are damaged or dirty. If so, they are forcibly directed to the defective product outflow conveyor 44. It is worth noting that the visual inspection sensor 46 can use a commercially available 2D camera, based on deep learning, to monitor online for deviations in the longitudinal and transverse sealing processes during bag heat sealing, as well as issues such as material clamping.

[0063] For example, the sorting mechanism 43 is provided with an inlet, a defective product outlet, and a good product outlet. The inlet is connected to multiple receiving troughs 4211, and the inlet can be connected to either the defective product outlet or the good product outlet to improve sorting efficiency and accuracy. In particular, the sorting mechanism 43 can use commercially available products, which is not the focus of this embodiment, and its specific structure and principle will not be described in detail here.

[0064] As another example, the oral cigarette filling and packaging device includes a main mounting frame 5, and a first mounting frame 11, a second mounting frame 21, a third mounting frame 41 and a packaging mounting frame 31 are all mounted on the main mounting frame 5.
