Description

Technical Field

[0001] This application relates to the field of cigarette processing equipment technology, and in particular to a device for loosening thin tobacco shreds. Background Technology

[0002] Heated cigarettes are a new type of electronic cigarette. They use a heating device to heat the cigarette to a certain temperature without igniting the tobacco. The tobacco is heated enough to produce smoke, resulting in a taste closer to that of a real cigarette. Heated cigarettes contain thin sheets of tobacco. To enhance the flavor, a large amount of flavorings and fragrances are usually sprayed onto these sheets. This results in a high sugar content in the tobacco, making it prone to sticking together and forming clumps. These clumps can cause equipment blockage during the cigarette rolling process, leading to machine downtime and affecting production stability.

[0003] To reduce the sticking of thin tobacco shreds, a thin tobacco shred loosening device is usually used to loosen the thin tobacco shreds before heating and rolling the cigarette. The thin tobacco shred loosening device is equipped with two needle rollers that rotate in opposite directions. When the tobacco shreds fall between the two needle rollers, they will be broken up by the two needle rollers. However, some of the tobacco shreds after being broken up are easy to continue to rotate with the needle rollers and thus be carried by the needle rollers to the feed port of the thin tobacco shred loosening device. Utility Model Content

[0004] Therefore, it is necessary to provide a thin sheet tobacco loosening device to solve the problem that some of the loosened tobacco tends to continue rotating with the needle roller and is thus carried by the needle roller to the feed inlet of the thin sheet tobacco loosening device.

[0005] A thin tobacco shred loosening device includes a housing, a first needle roller, a second needle roller, a first grate, and a second grate. The housing has an inlet and an outlet. The first and second needle rollers are rotatably mounted inside the housing. The first needle roller has multiple first elastic wire nails and multiple second elastic wire nails, which are staggered. A first gap exists between the outer surface of the first needle roller and the inner wall of the housing, and the first grate is located in the first gap. A second gap exists between the outer surface of the second needle roller and the inner wall of the housing, and the second grate is located in the second gap. As the first and second needle rollers rotate in opposite directions, the thin tobacco shreds entering the housing from the inlet are loosened by the first and second needle rollers and discharged from the outlet.

[0006] In one embodiment, the first grate is inclined relative to the feeding direction x, and the inclination angle of the first grate relative to the feeding direction x is α, and α < 90°; the second grate is inclined relative to the feeding direction x, and the inclination angle of the second grate relative to the feeding direction x is β, and β < 90°, wherein the feeding direction x is the direction from the feed inlet to the discharge outlet.

[0007] In one embodiment, the first grate is provided with a first connecting section at the end away from the first needle roller, and the first connecting section is attached to and detachably connected to the housing; and / or, the second grate is provided with a second connecting section at the end away from the second needle roller, and the second connecting section is attached to and detachably connected to the housing.

[0008] In one embodiment, the mounting position of the first connecting section on the inner wall of the housing is configured to be adjustable; the mounting position of the second connecting section on the inner wall of the housing is configured to be adjustable.

[0009] In one embodiment, the first grate has a plurality of first teeth arranged at intervals along the axial direction of the first needle roller, and the gap between adjacent first teeth corresponds to a first spring wire nail; the second grate has a plurality of second teeth arranged at intervals along the axial direction of the second needle roller, and the gap between adjacent second teeth corresponds to a second spring wire nail.

[0010] In one embodiment, the thin tobacco loosening device further includes a first guide plate and a second guide plate. The first guide plate and the second guide plate are spaced apart along the width direction y of the housing and surround to form a feeding channel. One end of the feeding channel is connected to the feeding port, and the other end is set towards the junction of the first needle roller and the second needle roller. Furthermore, along the feeding direction x, the cross-sectional area of ​​the feeding channel gradually decreases to guide the thin tobacco to the space between the first needle roller and the second needle roller.

[0011] In one embodiment, the first guide plate and / or the second guide plate are inclined relative to the feeding direction x, and the inclination angle of the first guide plate and / or the second guide plate relative to the feeding direction x is γ, where γ < α; γ < β.

[0012] In one embodiment, the thin tobacco loosening device further includes a hopper, one end of which is detachably installed at the feed inlet, and the other end has an opening that is inclined relative to the feed direction x.

[0013] In one embodiment, a mounting position is provided on one side of the outer wall of the housing for connecting an external support structure.

[0014] In one embodiment, the thin tobacco loosening device further includes a motor and a transmission gear set. The motor is connected to a first needle roller, and the first needle roller is connected to a second needle roller through the transmission gear set, so that the motor drives the first needle roller and drives the second needle roller to rotate through the transmission gear set.

[0015] Compared with the prior art, the thin tobacco shred loosening device provided in this application, by setting a first grate in the first gap and a second grate in the second gap, ensures that after the tobacco shreds fall between the first and second needle rollers and are broken up, some of the thin tobacco shreds, when continuing to rotate with the first needle roller to the first gap, will be blocked on the first grate and cannot continue to be carried onto the feed inlet. Similarly, some of the thin tobacco shreds, when continuing to rotate with the second needle roller to the second gap, will be blocked on the second grate and cannot continue to be carried onto the feed inlet.

[0026] Please see Figures 1 to 2This application provides a thin-sheet tobacco loosening device 100, which includes a housing 10, a first needle roller 20, a second needle roller 30, a first grate 41, and a second grate 42. The housing 10 has an inlet 11 and an outlet 12. The first needle roller 20 and the second needle roller 30 are rotatably mounted inside the housing 10. The first needle roller 20 is provided with a plurality of first spring wire nails 21 and a plurality of second spring wire nails 31. The first spring wire nails 21 and the second spring wire nails 31 are connected. 1. The needle roller 20 is staggered with the inner wall of the housing 10. A first gap 13 is formed between the outer surface of the first needle roller 20 and the inner wall of the housing 10. A first grate 41 is provided in the first gap 13. A second gap 14 is formed between the outer surface of the second needle roller 30 and the inner wall of the housing 10. A second grate 42 is provided in the second gap 14. As the first needle roller 20 and the second needle roller 30 rotate in opposite directions, the thin tobacco shreds that enter the housing 10 from the feed inlet 11 can be broken up by the first needle roller 20 and the second needle roller 30 and discharged from the discharge outlet 12.

[0027] It should be noted that the outer surface of the first needle roller 20 refers to the side of the first needle roller 20 facing away from the second needle roller 30, and similarly, the outer surface of the second needle roller 30 refers to the side of the second needle roller 30 facing away from the first needle roller 20. By setting the first grate 41 in the first gap 13 and the second grate 42 in the second gap 14, after the tobacco clump falls between the first needle roller 20 and the second needle roller 30 and is broken up, some of the thin tobacco flakes, when they continue to follow the first needle roller 20 to the first gap 13, will be blocked on the first grate 41 and will not be able to continue to be carried onto the feed inlet 11. Similarly, some of the thin tobacco flakes, when they continue to follow the second needle roller 30 to the second gap 14, will be blocked on the second grate 42 and will not be able to continue to be carried onto the feed inlet 11.

[0028] In one embodiment, the first grate 41 is inclined relative to the feeding direction x, and the inclination angle of the first grate 41 relative to the feeding direction x is α, where α < 90°; the second grate 42 is also inclined relative to the feeding direction x, and the inclination angle of the second grate 42 relative to the feeding direction x is β, where β < 90°, wherein the feeding direction x is the direction from the feed inlet 11 to the discharge outlet 12. That is, in this embodiment, the first grate 41 extends downward at an inclination from the inner wall of the housing 10 toward the direction close to the first needle roller 20, and the second grate 42 extends downward at an inclination from the inner wall of the housing 10 toward the direction close to the second needle roller 30. In this way, it can be ensured that the first grate 41 and the second grate 42 have sufficient extension length to fully block the thin tobacco shreds while making full use of the internal space of the housing 10.

[0029] Furthermore, to facilitate the assembly of the first grate 41 and the second grate 42 within the housing 10, 30° < α < 90°, 30° < β < 90°. For example, the values ​​of α and β can both be 50°, 60°, or 65°, etc., and can be set according to actual needs.

[0030] In one embodiment, the first grate 41 has a first connecting section 411 at the end away from the first needle roller 20. The first connecting section 411 is attached to and detachably connected to the housing 10. This facilitates the installation of the first grate 41 to the housing 10. Optionally, the first grate 41 and the first connecting section 411 are configured as an integral structure.

[0031] Furthermore, the mounting position of the first connecting section 411 on the inner wall of the housing 10 is adjustable. This allows for flexible adjustment of the mounting position of the first grate 41 according to different needs. Specifically, the mounting position can be adjusted up or down along the feeding direction x; or, the distance between the first grate 41 and the housing 10 can be adjusted along the thickness direction of the housing 10.

[0032] For example, in one embodiment, the first connecting segment 411 is connected to the housing 10 by a first tightening screw 413. By tightening the first tightening screw 413, the distance between the end of the first grate 41 and the outer surface of the first needle roller 20 can be adjusted so that a gap of 1 mm to 2 mm is maintained between the end of the first grate 41 and the outer surface of the first needle roller 20.

[0033] In another embodiment, the second grate 42 has a second connecting section 421 at the end away from the second needle roller 30. The second connecting section 421 is attached to and detachably connected to the housing 10. This facilitates the installation of the second grate 42 onto the housing 10. Optionally, the second grate 42 and the second connecting section 421 are configured as an integral structure.

[0034] Furthermore, the mounting position of the second connecting section 421 on the inner wall of the housing 10 is adjustable. This allows for flexible adjustment of the mounting position of the second grate 42 according to different needs. Specifically, the mounting position can be adjusted up or down along the feeding direction x; or, the distance between the second grate 42 and the housing 10 can be adjusted along the thickness direction of the housing 10, thereby adjusting the distance between the end of the second grate 42 and the outer surface of the second needle roller 30.

[0035] For example, in one embodiment, the second connecting segment 421 can adjust the distance between the end of the second grate 42 and the outer surface of the second needle roller 30 by tightening the second tightening screw 423, so that a gap of 1 mm to 2 mm is maintained between the end of the second grate 42 and the outer surface of the second needle roller 30.

[0036] In one embodiment, such as Figure 3As shown, the first grate 41 has a plurality of first teeth 412 spaced apart along the axial direction of the first needle roller 20, and the gap between adjacent first teeth 412 corresponds one-to-one with the first spring pins 21. The second grate 42 has a plurality of second teeth spaced apart along the axial direction of the second needle roller 30, and the gap between adjacent second teeth corresponds one-to-one with the second spring pins 31. In this way, collisions between the first spring pins 21 and the first teeth 412 can be avoided during the rotation of the first needle roller 20, and collisions between the second spring pins 31 and the second teeth can be avoided during the rotation of the second needle roller 30.

[0037] In one embodiment, the thin tobacco shred loosening device further includes a first guide plate 51 and a second guide plate 52. The first guide plate 51 and the second guide plate 52 are spaced apart along the width direction y of the housing 10 and form a feeding channel 53. One end of the feeding channel 53 is connected to the feeding port 11, and the other end is positioned towards the junction of the first needle roller 20 and the second needle roller 30. Furthermore, along the feeding direction x, the cross-sectional area of ​​the feeding channel 53 gradually decreases to guide the thin tobacco shreds between the first needle roller 20 and the second needle roller 30. This facilitates the smooth guidance of the thin tobacco shreds between the first needle roller 20 and the second needle roller 30.

[0038] Optionally, in one embodiment, the first guide plate 51 is inclined relative to the feeding direction x, and the inclination angle of the first guide plate 51 relative to the feeding direction x is γ, where γ < α. The second guide plate 52 is also inclined relative to the feeding direction x, and the inclination angle of the first guide plate 51 relative to the feeding direction x is γ, where γ < β. Specifically, the first guide plate 51 is located above the first grate 41 along the feeding direction x, and the second guide plate 52 is located above the second grate 42 along the feeding direction x.

[0039] In one embodiment, the sheet tobacco loosening device further includes a hopper 60, one end of which is detachably mounted to the feed inlet 11, and the other end has an opening 61, which is inclined relative to the feeding direction x. The opening 61 is used to connect to an upstream device to receive tobacco.

[0040] In one embodiment, a mounting position 15 is provided on one outer wall of the housing 10 for connecting to an external support structure. Optionally, the mounting position 15 can be connected to the external support structure by screws.

[0041] In one embodiment, the thin tobacco loosening device further includes a motor 70 and a transmission gear set 80. The motor 70 is connected to the first needle roller 20, and the first needle roller 20 is connected to the second needle roller 30 through the transmission gear set 80, so that the motor 70 drives the first needle roller 20 and drives the second needle roller 30 to rotate through the transmission gear set 80.

[0042] Specifically, the transmission gear set 80 includes a first gear 81 and a second gear 82. The output shaft of the motor 70 is connected to one end of the first needle roller 20, the other end of the first gear 81 is connected to the first needle roller 20, the second gear 82 meshes with the first gear 81, and the second gear 82 is connected to the second needle roller 30 and is used to drive the second needle roller 30 to rotate.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
