Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, specifically to a flavoring device for cigarette making. Background Technology

[0002] Tobacco shreds refer to tobacco leaves cut into shreds, granules, flakes, powder, or other shapes, then mixed with auxiliary materials, fermented, and stored to produce tobacco products suitable for sale and smoking. Among these processes, the flavoring of tobacco stems is a crucial step in tobacco processing. This involves accurately and evenly applying various flavorings and fragrances to the tobacco stems to improve their flavor and aroma, making them more palatable to consumers. During the addition of flavorings and fragrances, ensuring proper mixing of the tobacco stems and flavoring liquids is essential to prevent inconsistent flavors or uneven aromas.

[0003] The flavoring device for cigarette making in related technologies includes a drum, a conveying mechanism, and nozzles. The conveying mechanism feeds the tobacco stems to be flavored into the drum. The drum can rotate around its own axis, and a lifting plate is installed on the inner wall of the drum. When the drum rotates, the lifting plate can move the tobacco stems to be flavored to the highest point of the drum, and then cause the tobacco stems to fall to the lowest point of the drum under their own gravity. The nozzle is located inside the conveying mechanism and is configured to spray flavoring liquid onto the side opposite to the conveying mechanism, so that the flavoring liquid is mixed with the tobacco stems to be flavored when the drum rotates. However, in this process, the tobacco stems may accumulate on the lifting plate, affecting the mixing effect of the tobacco stems and flavoring liquid, and thus affecting the quality of the finished cigarettes.

[0047] Before explaining any embodiment of the present invention in detail, it should be understood that the present invention is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0048] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0049] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0050] In this invention, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0051] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints.

[0054] Example 1

[0055] Figure 1 A schematic diagram of the flavoring device for cigarette making provided in this embodiment is shown. Figure 2A schematic diagram of the hidden support mechanism 10 of the flavoring device for cigarette making provided in this embodiment is shown. Figure 3 yes Figure 2 A sectional view. For example... Figures 1-3 As shown, this embodiment provides a flavoring device for cigarette making. The device includes a support mechanism 10, a flipping mechanism 20, and a flavoring mechanism 40. The support mechanism 10 includes an outer cylinder 11. The flipping mechanism 20 includes a filter cylinder 21 and multiple dispersing plates 22. The filter cylinder 21 is rotatably disposed within the outer cylinder 11. Each dispersing plate 22 extends axially along the filter cylinder 21, and the multiple dispersing plates 22 are spaced apart circumferentially along the filter cylinder 21 and are all disposed on the inner wall of the filter cylinder 21. The flavoring mechanism 40 is disposed within the filter cylinder 21 and is configured to spray flavoring liquid into the filter cylinder 21. The dispersing plates 22 allow the tobacco stems inside the filter cylinder 21 to move from the lowest point to the highest point when the filter cylinder 21 rotates. The tobacco stems can then fall from the highest point of the filter cylinder 21. During this process, the tobacco stems can be fully mixed with the flavoring liquid sprayed by the flavoring mechanism 40, achieving the effect of flavoring the tobacco stems.

[0056] Furthermore, the support mechanism 10 also includes a mounting base 12, a first support base 13, and a second support base 14. The first support base 13 and the second support base 14 are spaced apart on the mounting base 12. The two ends of the outer cylinder 11 are respectively connected to the first support base 13 and the second support base 14 to provide stable support for the flipping mechanism 20. Specifically, a connecting cylinder 210 is provided at one end of the filter cylinder 21 near the first support base 13. The connecting cylinder 210 is rotatably connected to the first support base 13 through a rotating bearing to ensure the stability of the filter cylinder 21 during rotation. The first support base 13 has a feed inlet (not shown in the figure), which is connected to the inner cavity of the filter cylinder 21 through the connecting cylinder 210. The conveying mechanism can convey the tobacco stems to be flavored into the filter cylinder 21 through the feed inlet. The outer cylinder 11 has a discharge port (not shown in the figure) connected to the inner cavity of the filter cylinder 21. The tobacco stems that have completed the flavoring operation can be discharged from the discharge port and conveyed to the next process.

[0057] Figure 4 It shows Figure 2 A magnified view of a portion at point A. (See attached image.) Figure 4 and combined Figure 2 , Figure 3As shown, the end of the filter cartridge 21 facing away from the first support base 13 extends out of the outer cylinder 11 and into the second support base 14; the flipping mechanism 20 also includes a flipping drive assembly 23, which is disposed inside the second support base 14 and configured to drive the filter cartridge 21 to rotate. Specifically, the flipping drive assembly 23 includes a flipping driver 231, a drive gear 232, and a ring-shaped gear 233. The flipping driver 231 is mounted on the inner wall of the second support base 14, and the output end of the flipping driver 231 is connected to the drive gear 232. The ring-shaped gear 233 is sleeved on the end of the filter cartridge 21 that extends into the second support base 14, and the drive gear 232 meshes with the ring-shaped gear 233. When the flip drive 231 is activated, it drives the drive gear 232 to rotate, which in turn drives the ring gear 233 meshing with it to rotate, thereby realizing the rotation of the filter cylinder 21. When the filter cylinder 21 rotates, the dispersing plate 22 can move the tobacco stems inside the filter cylinder 21 from the lowest point to the highest point of the filter cylinder 21. Then, the tobacco stems can fall back to the lowest point of the filter cylinder 21 under their own gravity. During this falling process, the tobacco stems can come into contact with and mix with the fragrance liquid sprayed by the flavoring mechanism 40, thereby realizing the flavoring and aroma enhancement treatment of the tobacco stems. In this embodiment, the flip drive 231 is a drive motor.

[0058] like Figure 1 and Figure 3 As shown, the fragrance mixing mechanism 40 includes a first liquid supply unit 41, a liquid delivery pipe 42, and a fragrance spray head 43, which is disposed inside the filter cartridge 21. The first liquid supply unit 41 contains fragrance liquid and is disposed on one side of the mounting base 12. The outlet of the first liquid supply unit 41 is connected to the inlet of the fragrance spray head 43 through the liquid delivery pipe 42. The fragrance liquid in the first liquid supply unit 41 can be delivered to the fragrance spray head 43 through the liquid delivery pipe 42, and the fragrance spray head 43 can spray the fragrance liquid into the interior of the filter cartridge 21. In this embodiment, the specific composition of the fragrance liquid is not limited, and the operator can adjust the specific composition of the fragrance liquid according to the actual fragrance mixing needs. It should be noted that the first liquid supply unit 41 and the fragrance spray head 43 are both relatively mature structures in the prior art, and the specific structure and working principle of the first liquid supply unit 41 and the fragrance spray head 43 will not be described in detail in this embodiment.

[0059] In some embodiments, a dehumidification mechanism (not shown in the figure) is also provided inside the filter cartridge 21. This mechanism removes moisture from the filter cartridge 21 to prevent the tobacco stems from becoming moldy and also improves the stability of the entire device. In some embodiments, a hot air mechanism (not shown in the figure) is also provided inside the filter cartridge 21. This mechanism heats the tobacco stems inside the filter cartridge 21 to quickly dry and set their shape. It should be noted that both the dehumidification mechanism and the hot air mechanism are relatively mature devices in the prior art, and the specific structure and working principle of these mechanisms will not be described in detail in this embodiment.

[0060] Figure 5 It shows Figure 3 One of the partial structural diagrams. Figure 6 It shows Figure 5 A magnified view of point B. (See attached image.) Figures 5-6 and combined Figure 3 As shown, the flavoring device for cigarette making also includes an auxiliary shaking mechanism 30, which is arranged one-to-one with the dispersing plate 22. The auxiliary shaking mechanism 30 includes a vibrating block 31 that is vibratingly disposed on the corresponding dispersing plate 22. By setting a vibrating block 31 that can vibrate relative to each dispersing plate 22, when the vibrating block 31 vibrates, it can shake off the tobacco stems accumulated on the dispersing plate 22, thereby avoiding the accumulation of tobacco stems on the dispersing plate 22. This ensures that all tobacco stems can fully contact the flavoring liquid, thereby ensuring the flavoring effect on the tobacco stems and thus ensuring the quality of the finished cigarette.

[0061] Specifically, the dispersing plate 22 has a first mounting cavity 221, and the side of the dispersing plate 22 has a through hole 222 that communicates with the first mounting cavity 221; the auxiliary shaking mechanism 30 also includes a push plate 32 and a first elastic member 33. The push plate 32 is disposed in the first mounting cavity 221 and can be moved back and forth along the axial direction of the filter cylinder 21. The side of the push plate 32 has a push groove 320, and the width of the push groove 320 gradually increases in the direction away from the push plate 32; one end of the vibrating block 31 is accommodated in the push groove 320, and the other end extends out of the through hole 222; the two ends of the first elastic member 33 are respectively connected to the vibrating block 31 and the cavity wall of the first mounting cavity 221. When the push plate 32 reciprocates along the axial direction of the filter cylinder 21, the vibrating block 31 can move relative to the push plate 32 along the groove wall of the push groove 320, thereby changing the length of the vibrating block 31 extending out of the through hole 222 to achieve a vibration effect, thereby shaking off the tobacco stems accumulated at the dispersing plate 22 and ensuring the uniformity of the aroma-enhancing effect of the tobacco stems in the filter cylinder 21. In this embodiment, the first elastic element 33 is a first spring, which is easy to install and has a low cost.

[0062] Optionally, a first roller 34 is rotatably mounted on one end of the vibrating block 31 facing the bottom of the pushing groove 320. The first roller 34 rolls in contact with the groove wall and bottom of the pushing groove 320. By providing the first roller 34, friction when the vibrating block 31 moves relative to the pushing plate 32 can be reduced, wear can be reduced, and the service life of the entire flavoring device for cigarette making can be extended.

[0063] Optionally, the push plate 32 has multiple push grooves 320 spaced apart along its extension direction on both opposite sides. Each push groove 320 corresponds to a vibrating block 31 and a through hole 222. This design ensures that the tobacco stems accumulated at various positions on the push plate 22 can be shaken off. Specifically, the push plate 32 includes a push plate body 321 and multiple conical blocks 322. The push plate body 321 can reciprocate along the axial direction of the filter cylinder 21. Multiple conical blocks 322 are spaced apart along the axial direction of the filter cylinder 21 on both opposite sides of the push plate body 321. The width of the conical blocks 322 gradually decreases in the direction away from the push plate body 321. The push grooves 320 are formed between two adjacent conical blocks 322. The structure is simple and easy to process.

[0064] Figure 7 It shows Figure 3 The second part of the structural diagram. Figure 8 It shows Figure 7 A magnified view of point C. (See attached image.) Figures 7-8 and combined Figure 6 As shown, the first end of the push plate 32 is connected to the cavity wall of the first mounting cavity 221 via the second elastic member 35, and the second end of the push plate 32 extends out of the filter cylinder 21. An annular seat 50 is fixedly provided on the inner wall of the outer cylinder 11 facing the second end of the push plate 32. A plurality of protrusions 51 are also provided on the side of the annular seat 50 facing the push plate 32. The plurality of protrusions 51 are distributed circumferentially along the annular seat 50, and the width of each protrusion 51 gradually decreases in the direction away from the annular seat 50. The second end of the push plate 32 can alternately abut against the protrusions 51 or the annular seat 50 under the elastic action of the second elastic member 35. When the filter cylinder 21 rotates relative to the outer cylinder 11, the second end of the push plate 32 can alternately abut against the protrusions 51 or the annular seat 50 under the elastic action of the second elastic member 35, thereby realizing the reciprocating movement of the push plate 32 along the axial direction of the filter cylinder 21. No additional driving device is required, which can reduce the manufacturing cost of the flavoring device for cigarette making.

[0065] Optionally, a second roller 36 is rotatably provided at the second end of the push plate 32, and the second roller 36 rolls against the protrusion 51 or the annular seat 50. By providing the second roller 36, friction when the push plate 32 moves relative to the protrusion 51 or the annular seat 50 can be reduced, wear can be reduced, and the service life of the entire flavoring device for cigarette making can be extended.

[0066] In this embodiment, the protrusion 51 is semi-circular in shape, which improves the smoothness of the movement of the second roller 36 relative to the protrusion 51. Of course, in other embodiments, the protrusion 51 can also be triangular prism in shape, achieving the same effect.

[0067] like Figures 7-8As shown, the flavoring device for cigarette making also includes a spraying mechanism 60. The spraying mechanism 60 includes a support frame 61 and multiple nozzle assemblies 62. The support frame 61 is disposed in the filter cylinder 21 and extends along the axial direction of the filter cylinder 21. The multiple nozzle assemblies 62 are spaced apart on the support frame 61 along the extending direction of the support frame 61. The nozzle assemblies 62 can spray liquid into the filter cylinder 21. By spraying liquid into the filter cylinder 21, the tobacco stems inside the filter cylinder 21 can be wetted and atomized to further improve the flavoring effect of the tobacco stems. In addition, after long-term use, the nozzle assemblies 62 can be connected to an external cleaning liquid supply unit to clean the inside of the filter cylinder 21, thereby removing impurities from the tobacco stems remaining in the filter cylinder 21 and further ensuring the quality of the finished cigarettes.

[0068] Figure 9 A partial cross-sectional view of the nozzle assembly 62 provided in this embodiment is shown. (See attached image.) Figure 9 and combined Figure 8 As shown, the nozzle assembly 62 includes a cylinder 621, a switching valve 622, a main nozzle 623, and multiple side nozzles 624. The cylinder 621 is mounted on a support frame 61. The top of the cylinder 621 has a liquid inlet 6211, and the bottom of the cylinder 621 has a main spray hole 6212. Multiple side spray holes 6213 are provided on the side wall of the cylinder 621 at intervals along the circumference of the cylinder 621. Each side spray hole 6213 is equipped with a switching valve 622. The main nozzle 623 is installed at the main spray hole 6212. The multiple side nozzles 624 are installed one-to-one at the side spray holes 6213. Specifically, the support frame 61 has a hollow structure, with one end forming an inlet that connects to the second liquid supply unit (not shown in the figure). The support frame 61 also has outlets corresponding to the nozzle assemblies 62, and the outlets of the support frame 61 are connected to the corresponding liquid inlets 6211 to supply liquid to each nozzle assembly 62. When the liquid in the second liquid supply unit flows into the cylinder 621 of each nozzle assembly 62 through the support frame 61, the liquid can be sprayed out from the main nozzle 623 and sprayed onto the tobacco stems at various positions inside the filter cylinder 21 as the filter cylinder 21 rotates. At the same time, under the pressure of the liquid in the cylinder 621, the switching valve 622 opens, and the liquid can also be sprayed out from the side nozzles 624 to increase the spraying efficiency of the liquid and further improve the wetting and atomization effect of the tobacco stems.

[0069] It should be noted that when the spraying mechanism 60 is used to clean the filter cartridge 21, the cleaning liquid sprayed from the side spray holes 6213 can be reflected by the inner wall of the filter cartridge 21 and then splashed around the cartridge body 621, thereby playing an auxiliary cleaning role on the surface of the cartridge body 621 and its surroundings, so as to prevent a small amount of tobacco stem impurities from entering the filter cartridge 21 and adhering to the surface of the cartridge body 621, thereby effectively improving the cleaning effect inside the filter cartridge 21.

[0070] Furthermore, the switching valve 622 includes a valve ball 6221 and a third elastic element 6222. The side spray hole 6213 includes a first hole, a second hole, and a third hole that are connected in sequence and whose diameters increase in sequence. The first hole is disposed facing the inside of the cylinder 621, and the third hole is disposed facing the outside of the cylinder 621. The valve ball 6221 is installed in the third hole and can abut against the stepped surface formed by the second hole and the third hole. The third elastic element 6222 is installed in the second hole, and its two ends are respectively connected to the valve ball 6221 and the stepped surface formed by the first hole and the second hole. When the liquid pressure inside the cylinder 621 is high, the liquid can push the valve ball 6221 to move away from the third elastic element 6222, so that the side spray hole 6213 opens. At this time, the liquid can be sprayed out from the gap between the valve ball 6221 and the side spray hole 6213. After the liquid is sprayed, the valve ball 6221 can press against the step surface formed by the second hole and the third hole under the action of the elastic restoring force of the third elastic element 6222, thereby closing the side spray hole 6213.

[0071] Figure 10 A partial structural schematic diagram of the spray mechanism 60 provided in this embodiment is shown. For example... Figure 10 and combined Figure 8 As shown, the cylinder 621 is rotatably mounted on the support frame 61 to increase the spray range of the nozzle assembly 62. Furthermore, the spray mechanism 60 also includes a rotary drive assembly 63, which is configured to drive the nozzle assembly 62 to rotate.

[0072] Specifically, the rotary drive assembly 63 includes a drive plate 631, a first connecting member 632, a drive rack 633, and a driven gear 634. A second mounting cavity 501 is provided within the annular seat 50. The drive plate 631 is slidably disposed within the second mounting cavity 501. The drive rack 633 is mounted on the support frame 61 and connected to the drive plate 631 via the first connecting member 632. Each nozzle assembly 62 (specifically, a cylinder 621) is fitted with a driven gear 634, and all driven gears 634 mesh with the drive rack 633. When the drive plate 631 moves relative to the annular seat 50, the drive rack 633 drives all driven gears 634 to rotate, thereby achieving rotary spraying of material from the nozzle assembly 62.

[0073] Optionally, the rotary drive assembly 63 further includes a first reset member 635 and a second reset member (not shown in the figure). The two ends of the first reset member 635 are respectively connected to the cavity wall of the second mounting cavity 501 and the drive plate 631, and the two ends of the second reset member are respectively connected to the end of the support frame 61 away from the drive plate 631 and the second support base 14. Through the mutual cooperation between the first reset member 635 and the second reset member, the reciprocating movement of the drive plate 631 and the support frame 61 is realized. In this embodiment, both the first reset member 635 and the second reset member are springs, which facilitates installation and reduces cost.

[0074] Optionally, there may be multiple first reset members 635, and the number of first reset members 635 may be spaced apart along the circumference of the drive plate 631 to improve the stability of the drive plate 631 during movement and prevent it from deflecting during movement.

[0075] To achieve the reciprocating movement of the drive plate 631, the rotary drive assembly 63 further includes a second connector 636 and a movable block 637. One of the protrusions 51 has a stepped mounting hole, with the larger diameter end of the mounting hole facing away from the annular seat 50. The movable block 637 is movably positioned at the larger diameter end of the mounting hole. One end of the second connector 636 is connected to the movable block 637, and the other end of the second connector 636 passes through the smaller diameter end of the mounting hole and connects to the annular seat 50 before connecting to the drive plate 631. With this configuration, when the filter cartridge 21 rotates, the push plate 32 alternately abuts against the protrusion 51 or the annular seat 50, and can intermittently push the movable block 637 relative to the protrusion 51, thereby achieving the reciprocating movement of the drive plate 631. This design eliminates the need for a separate drive mechanism for moving the drive plate 631, thus simplifying the overall structure of the device and reducing manufacturing costs.

[0076] It should be noted that, in order to cooperate with the use of the rotary drive assembly 63, a semi-circular groove is provided on the side of the filter cylinder 21 facing the annular seat 50, so that the first connector 632 passes through the semi-circular groove and connects with the support frame 61. In order to avoid interference between the filter cylinder 21 and the first connector 632 when rotating, the filter cylinder 21 needs to be set to rotate alternately in 180° forward and reverse directions when working.

[0077] Example 2

[0078] This embodiment provides a flavoring device for cigarette making. The specific structure of this flavoring device for cigarette making is roughly the same as that of the flavoring device for cigarette making in Embodiment 1. The difference is that the fixing method of the spraying mechanism 60 is different.

[0079] Specifically, refer to Figure 1 and Figure 3 In this embodiment, an annular groove is provided on the inner wall of the filter cartridge 21 near the first support base 13. One end of the support frame 61 is slidably installed in the annular groove, and the other end of the support frame 61 extends out of the filter cartridge 21 and is fixed to the second support base 14. That is, the spraying mechanism 60 is fixedly installed, and when the filter cartridge 21 rotates, the spraying mechanism 60 can spray liquid or clean various positions in the filter cartridge 21. In this example, the filter cartridge 21 can rotate 360°.

[0080] Optionally, one end of the support frame 61 is slidably engaged with an annular groove via a bearing to ensure the stability of relative rotation between the two. The other end of the support frame 61 can be connected to the second support base 14 via fasteners, which is simple and secure.
