Description

Technical Field

[0001] This utility model relates to the field of cigarette technology, and in particular to a tobacco shred separation and loosening device. Background Technology

[0002] In the production and processing of dry ice expanded tobacco, material agglomeration often occurs after expansion by the hot-end sublimation device and air classification. If effective separation and loosening are not carried out, it will affect the production efficiency of subsequent shaping equipment. Existing separation and loosening devices loosen the tobacco uniformly. Some already loosened tobacco is loosened again, resulting in over-loosening and excessively fragmented tobacco. At the same time, because all tobacco has undergone loosening, the efficiency of tobacco processing is reduced.

[0003] Therefore, there is an urgent need to design a tobacco shred separation and loosening device to solve the above problems. Utility Model Content

[0004] One objective of this invention is to provide a tobacco shred separation and loosening device that can accurately separate tobacco shreds in different states, avoid excessive loosening of tobacco shreds, and improve the efficiency of tobacco shred processing.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A tobacco shred separation and loosening device includes an air separation mechanism, a receiving mechanism, and a conveying mechanism. The air separation mechanism includes a material channel with an air inlet on a first side. The receiving mechanism is located below the material channel and includes a straight-falling channel and a separation channel arranged side-by-side along a first direction. The straight-falling channel is near a second side of the material channel, and the separation channel is near the first side. The second side is opposite to the first side. A loosening component is provided in the straight-falling channel and is configured to loosen the tobacco shreds. The conveying mechanism is located below the receiving mechanism and is configured to convey the material downstream.

[0007] As an alternative, the loosening assembly includes a drive assembly and two loosening rollers, the two loosening rollers being parallel and pivotally connected to the separation channel, and the drive assembly being configured to drive the two loosening rollers to rotate.

[0008] As an alternative, the aforementioned drive assembly includes a first drive member and a transmission belt, the output end of the first drive member being coaxially connected to one of the aforementioned loosening rollers, and the transmission belt surrounding and tensioning both of the aforementioned loosening rollers; or

[0009] The aforementioned drive assembly includes a second drive member and a transmission gear. The output end of the drive member is coaxially connected to one of the aforementioned loosening rollers. Each of the aforementioned loosening rollers is coaxially connected to one of the aforementioned transmission gears, and the two aforementioned transmission gears mesh.

[0010] As an alternative, at least one of the aforementioned loosening rollers has a loosening portion protruding from its circumference.

[0011] As an optional solution, the size of the aforementioned air inlet is adjustable.

[0012] As an optional solution, the aforementioned air separation mechanism further includes an air inlet component, an adjusting component, and a locking component. The air inlet component includes a connecting portion and an air inlet section. The connecting portion is connected to the first side and has a groove on the side facing the first side. The adjusting component slides vertically with the groove and can cover the air inlet. The locking component is connected to the connecting portion and can tighten or loosen the adjusting component. The air inlet section is connected to the side of the connecting portion away from the first side and forms an air inlet channel. The air inlet channel communicates with the air inlet. The vertical direction is perpendicular to the first direction.

[0013] As an optional solution, a baffle is provided inside the material channel. One end of the baffle is connected to the second side, and the other end of the baffle is inclined downward and away from the second side. The other end of the baffle is spaced apart from the first side.

[0014] As an optional solution, the above-mentioned receiving mechanism also includes a material separating component, which protrudes between the above-mentioned direct-fall channel and the above-mentioned separation channel.

[0015] As an optional solution, both ends of the aforementioned material distribution component abut against the inner wall of the aforementioned material channel; and / or

[0016] The cross-section of the aforementioned material distribution component is conical.

[0017] As an optional solution, the aforementioned conveying mechanism is provided with a raised structure.

[0018] The beneficial effects of this utility model are:

[0019] Material is fed from the top of the material channel and falls along it. As horizontal air is continuously blown into the material channel from the air inlet, the material passes through the air inlet. Due to the weight difference between clumps and loose material, the loose material, being lighter, is blown to the second side of the material channel and falls into the straight drop channel. Without being loosened, the loose material falls directly onto the conveyor and is transported away. The clumps, being heavier, fall from the first side of the material channel and fall into the separation channel. In the separation channel, the loosening component loosens the clumps before they fall onto the conveyor.

[0020] In summary, this tobacco shred separation and loosening device can separate and process agglomerated and loose materials differently, avoiding over-processing of loose materials and causing the tobacco shreds to become too broken, while also saving tobacco shred processing time.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] This embodiment provides a tobacco shred separation and loosening device, which can accurately separate tobacco shreds in different states, avoid excessive loosening of the tobacco shreds, and improve the efficiency of tobacco shred processing. Figures 1-3As shown, the tobacco shred loosening device includes an air classifier 10, a receiving mechanism 20, and a conveying mechanism 30. The air classifier 10 includes a material channel 11, with an air inlet 111 on the first side 112 of the material channel 11. The receiving mechanism 20 is located below the material channel 11 and includes a straight drop channel 21 and a separation channel 22 arranged side by side along a first direction. The straight drop channel 21 is close to the second side 113 of the material channel 11, and the separation channel 22 is close to the first side 112. The second side 113 is arranged opposite to the first side 112. A portion of the loosening components 23 are provided in the straight drop channel 21. The loosening components 23 are configured to loosen the tobacco shreds. The conveying mechanism 30 is located below the receiving mechanism 20 and is configured to convey the material downstream.

[0034] In the aforementioned tobacco shred separation and loosening device, the material is fed from the top of the material channel 11 and falls down along the material channel 11. As horizontal (approximately in the X direction) air is continuously blown into the material channel 11 from the air inlet 111, the material passes through the air inlet 111. Due to the weight difference between the clumped material and the loose material, the loose material, being lighter, is blown to the material channel 11 near the second side 113 and falls into the direct drop channel 21. Without being loosened, the loose material falls directly onto the conveying mechanism 30 and is transported away. The clumped material, being heavier, falls from the material channel 11 near the first side 112 and falls into the separation channel 22. In the separation channel 22, the loosening component 23 loosens the clumped material before it falls onto the conveying mechanism 30. In summary, this tobacco shred separation and loosening device can separate and process agglomerated and loose materials differently, avoiding over-processing of loose materials and causing the tobacco shreds to become too broken, while also saving tobacco shred processing time.

[0035] Optionally, such as Figure 3 As shown, a baffle 15 is provided inside the material channel 11. One end of the baffle 15 is connected to the second side 113, and the other end of the baffle 15 is downward and inclined away from the second side 113. The other end of the baffle 15 is spaced apart from the first side 112. This arrangement prevents material from being discharged straight up and down from the top of the material channel 11, avoiding the situation where clumps of tobacco fall from the second side 113 into the direct-fall channel 21, resulting in clumps of tobacco entering the conveying mechanism 30 without being dispersed. Furthermore, this arrangement allows the baffle 15 to buffer the discharge, preventing excessive material discharge at once and excessive force that could cause the tobacco to fall too quickly during the air separation process, resulting in insufficient separation. Of course, in other embodiments, if the baffle 15 is not provided in the material channel 11, the opening at the top of the material channel 11 can be made smaller, basically the same as the opening of the separation channel 22 and located above the separation channel 22.

[0036] Optionally, such as Figure 2As shown, the loosening assembly 23 includes a drive assembly 231 and two loosening rollers 232. The two loosening rollers 232 are parallel and pivotally connected to the separation channel 22. The drive assembly 231 is configured to drive the two loosening rollers 232 to rotate. With the above arrangement, the drive assembly 231 drives the two loosening rollers 232 to rotate, and the agglomerated material is loosened by passing through the two loosening rollers 232.

[0037] In an alternative embodiment, such as Figure 2 As shown, the drive assembly 231 includes a second drive member 2311 and a transmission gear 2312. The output end of the second drive member 2311 is coaxially connected to one of the loosening rollers 232. Each loosening roller 232 is coaxially connected to a transmission gear 2312, and the two transmission gears 2312 mesh. With the above configuration, the second drive member 2311 drives the two loosening rollers 232 to rotate.

[0038] In another alternative embodiment (not shown), the drive assembly 231 includes a first drive member and a drive belt. The output end of the first drive member is coaxially connected to one of the loose rollers 232. The drive belt surrounds the two loose rollers 232 and is tensioned. This scheme enables the two loose rollers 232 to rotate simultaneously via the drive belt.

[0039] Optionally, such as Figure 2 As shown, at least one loosening roller 232 has a loosening portion 2321 protruding from its circumference. In this embodiment, both loosening rollers 232 have multiple loosening portions 2321 protruding from their circumferences. When material passes through the loosening roller 232, the loosening portions 2321 penetrate into the clumps of material, thereby loosening the clumps. Optionally, the loosening portions 2321 are cone-shaped, which allows them to penetrate the clumps of material more effectively.

[0040] Optionally, the size of the air inlet 111 is adjustable. With the above settings, the amount of air entering the material channel 11 can be adjusted relatively easily, and the size of the air inlet 111 can be adjusted for materials with different degrees of agglomeration, without having to replace different models of fans.

[0041] In an alternative embodiment, such as Figure 1 and Figure 2As shown, the air separation mechanism 10 also includes an air inlet 12, an adjusting member 13, and a locking member 14. The air inlet 12 includes a connecting part 121 and an air inlet 122. The connecting part 121 is connected to the first side 112 and has a groove 1211 on the side facing the first side 112. The adjusting member 13 slides with the groove 1211 in the vertical direction (i.e., the Z direction in the figure) and can cover the air inlet 111. The locking member 14 is connected to the connecting part 121 and can tighten or loosen the adjusting member 13. The air inlet 122 is connected to the side of the connecting part 121 away from the first side 112 and forms an air inlet channel 1221. The air inlet channel 1221 communicates with the air inlet 111 and is perpendicular to the first direction in the vertical direction. With the above configuration, by loosening the locking member 14, the adjusting member 13 can slide up and down to adjust its height, thereby changing the area covered by the adjusting member 13 of the air inlet 111. When the locking member 14 is tightened, the locking member 14 abuts against the surface of the adjusting member 13, and the position of the adjusting member 13 is fixed.

[0042] Optionally, the air inlet 122 is funnel-shaped, with a smaller opening at the end near the material channel 11, which facilitates connection to the fan. At the same time, the funnel shape can accelerate the airflow within the air inlet channel 1221, ensuring the separation effect of the tobacco shreds.

[0043] Optionally, such as Figure 3 and Figure 4 As shown, the receiving mechanism 20 also includes a material distributor 24, which protrudes between the direct-fall channel 21 and the separation channel 22. This prevents material mixing. Furthermore, the material distributor 24 has a tapered cross-section, which guides the falling material.

[0044] Optionally, the two ends of the material distribution component 24 abut against the inner walls of the material channel 11, that is, the two opposing inner walls of the material channel 11 along the second direction, to ensure comprehensive material distribution. The second direction is... Figure 1 The Y direction is perpendicular to both the X and Z directions.

[0045] Optionally, see Figure 3 and Figure 4 The direct-fall channel 21 and the separation channel 22 are connected to the lower side of the mounting plate 25, the material channel 11 is installed on the upper side of the mounting plate 25, and the material distribution component 24 protrudes from the upper side of the mounting plate 25 and is located inside the material channel 11. Through the setting of the mounting plate 25, the connection and installation of the material channel 11, the direct-fall channel 21, the separation channel 22 and the material distribution component 24 can be realized.

[0046] Optionally, such as Figure 1 As shown, the conveying mechanism 30 is provided with a protruding structure 31. This protruding structure 31 continues to loosen the tobacco shreds as they are conveyed downstream. In an optional embodiment, as... Figure 1As shown, the protrusion structure 31 is constructed as a V-shaped structure and multiple protrusions are provided. In another optional embodiment, the protrusion structure 31 can also be constructed as a wave shape, which is not limited here.

[0047] 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
