Description

Technical Field

[0001] This utility model relates to the field of tobacco preparation technology, and in particular to a feeding guide and feeding cylinder and a flavoring machine. Background Technology

[0002] Currently, the tobacco flavoring process in the tobacco industry generally uses drum-type equipment. Its core principle is to achieve the dispersion, mixing, and tumbling of tobacco shreds through the synergistic action of the drum and rakes. When the filling mechanism puts the tobacco shreds into the drum, to avoid interference between the rakes and the filling mechanism, rakes are generally not installed at the drum's inlet end. However, the absence of rakes results in a smooth inner surface of the drum, insufficient power for downstream conveying, and the tobacco shreds cannot be pushed forward in time at the drum's inlet end, leading to accumulation. This disrupts the continuity of tobacco shred transport, causing flow fluctuations, which directly affects the uniformity of liquid absorption, negatively impacting the intrinsic quality and homogenization effect of the tobacco shreds, and ultimately reducing the overall quality stability of the product.

[0003] Secondly, during the production process, the continuous accumulation of tobacco at the inlet of the drum will cause a large amount of tobacco to leak out onto the ground, which not only wastes raw materials and increases production costs, but also has an adverse impact on the environmental hygiene of the production site, and also increases the difficulty of on-site maintenance.

[0004] Therefore, it is urgent to study a material feeding and stirring cylinder and a fragrance adding machine to solve the above problems. Utility Model Content

[0007] The material feeding and lifting cylinder includes:

[0008] The cylinder body includes a feeding area and a lifting area, the feeding area and the lifting area are arranged adjacent to each other along the axial direction of the cylinder body, and the feeding area is located upstream of the lifting area;

[0009] A plurality of spiral plates are disposed in the feeding area and are arranged at intervals around the axis of the cylinder body. The spiral plates are spiral in shape and extend downstream around the axis of the cylinder body.

[0010] A plurality of rakes are distributed in the material-lifting area. The rakes are used to lift the internal material during the rotation of the cylinder body. The ends of the rakes have a smooth curved surface structure.

[0011] As an optional technical solution for a material guiding and lifting cylinder, the height of the spiral plate first increases and then remains constant along the axial direction of the cylinder body downstream.

[0012] As an optional technical solution for a material guiding and feeding cylinder, two adjacent spiral plates are arranged at a projection interval along the axial direction of the cylinder body.

[0013] As an optional technical solution for a material guiding and lifting cylinder, along the axial direction of the cylinder body, the lifting zone includes a buffer zone and a main lifting zone, with the buffer zone located upstream of the main lifting zone;

[0015] As an optional technical solution for a material guiding and lifting cylinder, the length of several rake nails in each of the first lifting groups gradually increases downstream along the axial direction of the cylinder body.

[0016] As an optional technical solution for a material guiding and lifting cylinder, in the main lifting area, a number of rakes form a number of second lifting groups. The number of rakes in each second lifting group are arranged at intervals along the axial direction of the cylinder body, and the number of second lifting groups are arranged at intervals around the axial direction of the cylinder body. In the main lifting area, the number of rakes in each second lifting group has the same length.

[0017] As an optional technical solution for a material guiding and lifting cylinder, the first lifting group and the second lifting group correspond one-to-one, and the length of the longest rake nail in the first lifting group is equal to the length of the rake nail in the second lifting group.

[0018] As an optional technical solution for the material guiding and lifting cylinder, the rake nails in two adjacent first lifting groups are staggered; and / or,

[0019] The rakes in two adjacent second rake groups are staggered.

[0020] As an optional technical solution for a material guiding and lifting cylinder, the lifting zone further includes a discharge zone, which is located downstream of the main lifting zone. In the discharge zone, a plurality of rakes form a plurality of third lifting groups. The plurality of rakes in each third lifting group are arranged at intervals around the axis of the cylinder body. The plurality of third lifting groups are arranged at intervals along the axis of the cylinder body. Downstream along the axis of the cylinder body, the length of the rakes in each third lifting group gradually decreases.

[0021] A fragrance adding machine includes a nozzle and a material guiding and feeding cylinder as described in any of the above technical solutions, wherein the nozzle is disposed on the cylinder body.

[0022] This utility model has at least the following beneficial effects:

[0023] This utility model provides a material guiding and lifting cylinder and a flavoring machine. The material guiding and lifting cylinder includes a cylinder body, several spiral plates, and several rakes. The cylinder body includes a feeding zone and a lifting zone, which are arranged adjacent to each other along the axis of the cylinder body, with the feeding zone located upstream of the lifting zone.

Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0037] In this application, 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 values ​​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.

[0040] like Figures 1 to 3 As shown, this embodiment provides a material guiding and lifting cylinder, which includes a cylinder body 100, a plurality of spiral plates 200, and a plurality of rakes 300. The cylinder body 100 includes a feeding area 110 and a lifting area, which are arranged adjacent to each other along the axial direction of the cylinder body 100, with the feeding area 110 located upstream of the lifting area. A plurality of spiral plates 200 are disposed in the feeding area 110 and are evenly spaced around the axial direction of the cylinder body 100. The spiral plates 200 are spiral-shaped and extend downstream around the axial direction of the cylinder body 100. A plurality of rakes 300 are dispersedly disposed in the lifting area. The rakes 300 are used to lift internal materials during the rotation of the cylinder body 100, and the ends of the rakes 300 have a smooth curved surface structure.

[0041] The aforementioned design allows the tobacco shreds to be placed between adjacent spiral plates 200 when fed through the filling mechanism, avoiding collisions and interference. As the cylinder body 100 rotates, it drives the spiral plates 200, uniformly transporting the tobacco shreds downstream. This solves the problem of tobacco shreds accumulating at the inlet, thus improving the continuity of tobacco shred transport and the uniformity of liquid absorption. This positively impacts the intrinsic quality of the tobacco shreds and the homogenization process, ultimately ensuring the overall quality stability of the product. Secondly, during production, it reduces or even eliminates tobacco shreds leaking onto the ground, lowering raw material waste and production costs, reducing adverse environmental impacts on the production site, and simplifying maintenance.

[0042] The smooth curved surface of the end effectively prevents sharp edges from cutting and tearing the tobacco. For example, the end of the rake 300 near the axis of the tube body 100 is hemispherical.

[0043] In some embodiments, the height of the spiral plate 200 increases first and then remains constant downstream along the axial direction of the cylinder body 100. The lower height of the spiral plate 200 in the upstream section helps to provide more clearance space and avoid interference between the filling mechanism and the spiral plate 200; and the conveying capacity of the spiral plate 200 gradually increases first and then remains constant along the upstream to downstream direction, which helps to adapt to the state when the tobacco is fed, that is, when the tobacco is fed to the inlet of the cylinder body 100, the thickness of the tobacco near the edge of the cylinder body 100 is less than the thickness downstream.

[0044] To reduce the number of spiral plates 200 and save costs, in some embodiments, adjacent spiral plates 200 are arranged with a projection interval in the axial direction of the cylinder body 100. This arrangement also increases the distance between adjacent spiral plates 200 to some extent, reducing the probability of collision between the packing mechanism and the spiral plates 200. In some embodiments, there are nine spiral plates 200. In other embodiments, there may be six to twelve spiral plates 200.

[0045] In some embodiments, along the axial direction of the cylinder body 100, the material-flipping area includes a buffer zone 120 and a main material-flipping area 130, with the buffer zone 120 located upstream of the main material-flipping area 130. In the buffer zone 120, a plurality of rakes 300 form a plurality of first material-flipping groups 121, with the plurality of rakes 300 in each first material-flipping group 121 being evenly spaced along the axial direction of the cylinder body 100, and the plurality of first material-flipping groups 121 being evenly spaced around the axial direction of the cylinder body 100, so that the material-flipping action can be continuously completed during the rotation of the cylinder body 100.

[0046] Under the premise of satisfying the downstream movement of tobacco shreds, along the axial direction of the cylinder body 100, the length of several rake nails 300 in each first agitator group 121 gradually increases, and the length of the rake nails 300 located upstream is smaller, so as to reduce the force of agitating the tobacco shreds and thus reduce the damage to the tobacco shreds.

[0047] To improve the reliability of material turning, in the main turning zone 130, several rakes 300 form several second turning groups 131. The rakes 300 in each second turning group 131 are evenly spaced along the axial direction of the cylinder body 100, and the several second turning groups 131 are also evenly spaced around the axial direction of the cylinder body 100. Furthermore, in the main turning zone 130, the lengths of the rakes 300 in each second turning group 131 are the same. For example, in the main turning zone 130, several rakes 300 form 13 second turning groups 131. Each second turning group 131 includes 10 to 20 rakes 300. Within the same second turning group 131, the spacing between adjacent rakes 300 is 80mm to 200mm to ensure that the tobacco is not excessively squeezed or rubbed between the rakes 300. The spacing of the rakes 300 can also be reasonably set according to the spreading uniformity, mixing effect, and movement trajectory. It should be noted that the main scraping area 130 is equipped with nozzles to spray flavoring liquid. The area is densely covered with rake nails 300, which can scrape the material more evenly. At the same time, the tobacco shreds maintain good looseness during the throwing process, which significantly promotes the uniform absorption of flavoring liquid by the tobacco shreds.

[0048] To facilitate the smooth transport of tobacco, in some embodiments, the first agitator group 121 and the second agitator group 131 correspond one-to-one, with the longest rake nail 300 in the first agitator group 121 having the same length as the rake nail 300 in the second agitator group 131. This arrangement allows the first agitator group 121 to gradually increase its agitation capacity as the tobacco is transported forward, i.e., downstream, eventually reaching the agitation capacity of the second agitator group 131, achieving a smooth transition between the two. In some embodiments, in the buffer zone 120, the maximum length of the rake nail 300 in each first agitator group 121 is 120mm, and the minimum length is 80mm. For example, each first agitator group 121 has four rake nails 300 with lengths of 80mm, 90mm, 100mm, and 120mm respectively. In the main agitator area 130, all rake nails 300 have a length of 120mm.

[0049] To improve the uniformity of material turning, in some embodiments, the rake nails 300 in two adjacent first agitator groups 121 are staggered. That is, there is a gap between two adjacent rake nails 300 in the same first agitator group 121, and in two adjacent first agitator groups 121, the rake nails 300 in one first agitator group 121 correspond to the gap in the other first agitator group 121. Similarly, the rake nails 300 in two adjacent second agitator groups 131 are staggered.

[0050] In some embodiments, the feeding zone further includes a discharge zone 140, located downstream of the main feeding zone 130. In the discharge zone 140, a plurality of rakes 300 form a plurality of third feeding groups 141. The rakes 300 in each third feeding group 141 are evenly spaced around the axis of the cylinder body 100. The lengths of the rakes 300 in the third feeding groups 141 gradually decrease downstream along the axis of the cylinder body 100. The rakes 300 in the same third feeding group 141 have the same length. This arrangement allows for a natural transition during the tobacco discharge process, ensuring stable tobacco output and preventing tobacco accumulation or uneven distribution at the discharge end. Furthermore, since the tobacco has already undergone flavoring, the feeding process does not need to be overly vigorous. Therefore, the gradually decreasing length of the rakes 300 helps reduce the force applied to the tobacco during feeding, minimizing damage.

[0051] To ensure uniform material discharge, the rakes 300 in adjacent third agitator groups 141 are staggered along the axial direction of the cylinder body 100. Along the axial direction of the cylinder body 100, the distance between two adjacent rakes 300 in the first agitator group 121 is H1, the distance between two adjacent rakes 300 in the second agitator group 131 is H2, and the distance between two adjacent third agitator groups 141 is H3, where H1 is greater than H2, and H3 is greater than H2. For example, H1 = H3 = 2 * H2.

[0052] In some embodiments, the cylinder body 100 has a diameter of 2m and a length of 4m. In some embodiments, the buffer zone 120 has a length of 900mm. The discharge zone 140 has a length of 600mm to 800mm.

[0053] In some embodiments, both the cylinder body 100 and the rake 300 are made of wear-resistant and corrosion-resistant alloy material to adapt to the flavoring liquid environment and extend the service life of the equipment. The angle between the rake 300 and the radius at the connection point between the rake 300 and the cylinder body 100 is greater than zero and less than 30°. In other words, the extension direction of the rake 300 does not pass through the axis of the cylinder body 100 to reduce the severe impact of the tobacco shreds during the rotation of the cylinder body 100.

[0054] In some embodiments, the surface of the rake 300 is smoothed to significantly reduce the frictional resistance when the tobacco shreds come into contact with the surface of the rake 300. This design reduces the breakage rate of the tobacco shreds, directly leading to a significant improvement in product quality and an effective reduction in production costs. On the one hand, it maintains the integrity of the tobacco shreds, improving the appearance quality and filling value of the finished tobacco shreds; on the other hand, it reduces raw material loss, improves raw material utilization, and generates significant economic benefits.

[0055] In the above embodiments, the arrangement, height, and angle of the rake nails 300 are precisely calculated and optimized to ensure that the tobacco is thoroughly agitated during the rotation of the cylinder body 100, breaking up tobacco clumps, allowing the tobacco to fully loosen and spread out, increasing the contact area with the atomized flavor liquid, and achieving uniform distribution and deep penetration of the flavor liquid on the surface of the tobacco.

[0056] This embodiment also provides a fragrance adding machine, which includes a nozzle (not shown in the figure) and a material guiding and feeding cylinder as described in any of the above embodiments, with the nozzle located on the cylinder body 100.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
