Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, specifically to a device for blending and homogenizing cigarette stems. Background Technology

[0002] Cigarettes are tobacco products made by rolling tobacco shreds into strips using cigarette paper; they are also known as paper cigarettes, cigarettes, or cigarette rolls. The blending of tobacco stems is a crucial step in the tobacco processing production line. In this step, materials such as tobacco stems, expanded tobacco, and sheet tobacco need to be blended into the tobacco shreds in different proportions. To ensure the stability of cigarette quality, these materials must be evenly blended into the dried tobacco shreds according to a predetermined ratio.

[0003] In related technologies, electronic belt scales are typically used to weigh the stems before continuously and evenly mixing them into the batch of tobacco according to a preset ratio. However, due to the small amount of tobacco being mixed, the conveying speed of the electronic belt scale is slow, resulting in a thick accumulation of stems on the scale. The adjustable amount of stems is limited, causing the stems to fall in layers at the end of the scale. These layered stems then accumulate intermittently on the conveyor belt below, resulting in gaps on the belt. Furthermore, the significant height difference between the electronic belt scale's discharge port and the conveyor belt below causes the fallen tobacco to scatter more widely, exacerbating the problem of gaps on the belt. These gaps lead to uneven distribution of stems in the tobacco, negatively impacting tobacco quality. Simultaneously, the accumulation of stems and the gaps on the belt also cause uneven moisture content during transport, further aggravating the quality issue.

[0004] Therefore, there is an urgent need for a device for mixing and homogenizing stalks and fibers to solve the above problems. Utility Model Content

[0021] As a preferred embodiment of the filament blending and uniform material device provided by this utility model, the feeding shaft is provided with a plurality of through holes arranged at intervals along its axial direction, and the distributing rods are inserted into the through holes one by one.

[0022] As a preferred embodiment of the filament blending and homogenizing device provided by this utility model, the rotation direction of the feeding shaft is opposite to the transmission direction of the first transmission mechanism, and the rotation speed of the feeding shaft is greater than the transmission speed of the first transmission mechanism.

By setting an auxiliary material-feeding mechanism, the material falling from the discharge end of the first conveying mechanism must pass through the material-feeding gap formed between the first and second material-feeding baffles before falling onto the second conveying mechanism, so that most of the material falls in the middle position of the conveying surface of the second conveying mechanism, thereby reducing or even avoiding the occurrence of blank areas on the second conveying mechanism, and further ensuring the quality of finished cigarettes.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0048] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can be performed by one part, one component, or a combination of multiple parts.

[0049] In this utility model, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this utility model. Furthermore, in the context, it should be understood that when one element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent the direct orientation but can also be understood as the lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0050] Figure 1 A schematic diagram of the structure of the stem and filament mixing and homogenizing device provided in this embodiment is shown. Figure 2 A cross-sectional schematic diagram of the stem and filament mixing and homogenizing device provided in this embodiment is shown. Figures 1-2 As shown, this embodiment provides a skewer blending and homogenizing device, which includes a first conveying mechanism 10, a second conveying mechanism 20, a material feeding mechanism 40, and an auxiliary material dropping mechanism 50. The first conveying mechanism 10 is configured to convey materials; the second conveying mechanism 20 is located downstream of the first conveying mechanism 10 and can receive materials on the first conveying mechanism 10, with the inlet end of the second conveying mechanism 20 located below the outlet end of the first conveying mechanism 10; the material feeding mechanism 40 is disposed at the outlet end of the first conveying mechanism 10 and is configured to feed materials onto the first conveying mechanism 10. The material on mechanism 10 is moved; the auxiliary material dropping mechanism 50 includes a first material dropping baffle 51 and a second material dropping baffle 52. The first material dropping baffle 51 and the second material dropping baffle 52 are located vertically between the first transmission mechanism 10 and the second transmission mechanism 20, and are spaced apart horizontally along the transmission direction of the first transmission mechanism 10; a material dropping gap is formed between the first material dropping baffle 51 and the second material dropping baffle 52. The width of the material dropping gap gradually decreases from top to bottom, and the material on the first transmission mechanism 10 falls from the material dropping gap onto the second transmission mechanism 20.

[0051] The tobacco blending and homogenizing device provided in this embodiment, by setting a material-dispersing mechanism 40, can disperse the material on the first conveying mechanism 10 before it falls onto the second conveying mechanism 20, avoiding intermittent accumulation of material on the second conveying mechanism 20, thereby ensuring the uniformity of tobacco blending and ensuring the quality of the finished cigarettes. By setting an auxiliary material-feeding mechanism 50, the material falling from the discharge end of the first conveying mechanism 10 must pass through the material-feeding gap formed between the first material-feeding baffle 51 and the second material-feeding baffle 52 before falling onto the second conveying mechanism 20, so that most of the material falls in the middle of the conveying surface of the second conveying mechanism 20, thereby reducing or even avoiding blank areas on the second conveying mechanism 20, and further ensuring the quality of the finished cigarettes.

[0052] It should be noted that in this embodiment, the material is specifically shredded tobacco stems. Of course, in other embodiments, the material may also be other expanded shreds or thin sheets that need to be mixed into the tobacco shreds in a preset proportion.

[0053] Optionally, the filament blending and homogenizing device further includes a cover 30, which is disposed between the first transmission mechanism 10 and the second transmission mechanism 20, covering the discharge end of the first transmission mechanism 10 and the inlet end of the second transmission mechanism 20. The material feeding mechanism 40 and the auxiliary material dropping mechanism 50 are both mounted on the cover 30. By providing the cover 30, on the one hand, it provides installation positions for the material feeding mechanism 40 and the auxiliary material dropping mechanism 50, ensuring stable installation and coordinated operation of each mechanism; on the other hand, it also prevents material from the first transmission mechanism 10 from flying during its transfer to the second transmission mechanism 20. In this embodiment, the cover 30 is a stainless steel shell, which has good structural stability.

[0054] like Figure 2As shown, along the transmission direction of the first transmission mechanism 10, the first discharge baffle 51 is located upstream of the second discharge baffle 52; the angle between the first discharge baffle 51 and the vertical direction is 60° to 65°; and / or the angle between the second discharge baffle 52 and the vertical direction is 25° to 30°. That is to say, the bearing surface of the second discharge baffle 52 is steeper than the bearing surface of the first discharge baffle 51. When most of the material on the first transmission mechanism 10 falls, it will first fall onto the bearing surface of the first discharge baffle 51, and then onto the bearing surface of the second discharge baffle 52. The first discharge baffle 51 has a relatively flat bearing surface, which increases the dwell time of the material and acts as a buffer, significantly reducing the material's speed. The material then falls onto the bearing surface of the second discharge baffle 52, which has a steeper bearing surface, reducing the dwell time and dispersing large pieces of material. Simultaneously, the first and second discharge baffles work together to correct the material's falling position, ensuring that all material falls to the center of the transmission surface of the second transmission mechanism 20. Of course, the angles between the first and second discharge baffles 51 and the vertical direction are not limited to the above ranges; designers can adjust them adaptively according to actual processing requirements.

[0055] Figure 3 A side view of the filament mixing and homogenizing device provided in this embodiment is shown. Figure 4 yes Figure 3 A magnified view of a portion at point A. (See attached image.) Figures 3-4 and combined Figure 2 As shown, the auxiliary material feeding mechanism 50 also includes an angle adjustment component 53. Both the first material feeding baffle 51 and the second material feeding baffle 52 are connected to the angle adjustment component 53. The angle adjustment component 53 is configured to adjust the angle between the corresponding first material feeding baffle 51 or second material feeding baffle 52 and the vertical direction. By setting the angle adjustment component 53, the inclination angle of the first material feeding baffle 51 or the second material feeding baffle 52 can be adjusted, thereby ensuring that the material formed between the first material feeding baffle 51 and the second material feeding baffle 52 has a suitable width. This ensures that the material on the first conveying mechanism 10 falls onto the conveying surface of the second conveying mechanism 20 at a suitable speed, and falls as close as possible to the middle position of the conveying surface of the second conveying mechanism 20.

[0056] Specifically, the angle adjustment assembly 53 includes an adjustment shaft 531, a connecting rod 532, and an adjustment track 533. The adjustment shaft 531 is connected to the corresponding first discharge baffle 51 or second discharge baffle 52 and is rotatably mounted on the cover 30. One end of the connecting rod 532 is connected to the adjustment shaft 531. The adjustment track 533 is arc-shaped and fixed to the cover 30, and the other end of the connecting rod 532 is slidably connected to the adjustment track 533. When it is necessary to adjust the tilt angle of the first discharge baffle 51 or the second discharge baffle 52, the connecting rod 532 can be swung along the extension direction of the adjustment track 533, thereby driving the corresponding discharge baffle to rotate through the adjustment shaft 531. The structure is simple and easy to operate.

[0057] Furthermore, the angle adjustment assembly 53 also includes a locking member 534, which is used to lock the other end of the connecting rod 532 onto the adjustment track 533. By setting the locking member 534, the adjusted connecting rod 532 can be locked onto the adjustment track 533, preventing the first or second discharge baffle 51 from deflecting under the action of the material's gravity when the material falls onto the first discharge baffle 51 or the second discharge baffle 52, thus affecting the material's discharge position.

[0058] like Figure 4 As shown, the adjusting track 533 is provided with a track groove. The locking component 534 includes a locking screw 5341 and two locking nuts 5342. One end of the locking screw 5341 is threaded to the end of the connecting rod 532 away from the adjusting shaft 531. The other end of the locking screw 5341 passes through the track groove on the adjusting track 533. The two locking nuts 5342 are located on both sides of the adjusting track 533 and are screwed onto the locking screw 5341, thereby locking the connecting rod 532 to the adjusting track 533. When it is necessary to adjust the inclination angle of the first discharge baffle 51 or the second discharge baffle 52, one of the locking nuts 5342 can be loosened, and then the locking screw 5341 can be moved so that the connecting rod 532 can slide along the track direction of the track groove. The adjustment process is convenient and quick.

[0059] Optionally, both ends of the adjusting rail 533 are fixed to the cover 30 by the first screw 61 to achieve stable installation of the adjusting rail 533 on the cover 30. The screw connection has the advantages of convenient operation and tight connection.

[0060] Optionally, one end of the connecting rod 532 is fixed to the adjusting shaft 531 by the second screw 62 to achieve a stable connection between the second screw 62 and the adjusting shaft 531. The screw connection has the advantages of convenient operation and tight connection.

[0061] In this embodiment, each material discharge baffle corresponds to two angle adjustment components 53. That is, the first material discharge baffle 51 is provided with angle adjustment components 53 at both ends along the transmission direction of the second transmission mechanism 20, and the second material discharge baffle 52 is provided with angle adjustment components 53 at both ends along the transmission direction of the second transmission mechanism 20, so as to ensure the stability of the first material discharge baffle 51 or the second material discharge baffle 52 during the tilt angle adjustment process.

[0062] Figure 5 It shows Figure 2 A magnified view of a section at point B. Figure 6 A schematic diagram of the material feeding shaft 411 provided in this embodiment is shown. Figures 5-6 and combined Figure 1 As shown, the feeding mechanism 40 includes a feeding assembly 41 and a feeding drive assembly 42. The feeding assembly 41 includes a feeding shaft 411 and multiple feeding rods 412. The multiple feeding rods 412 are arranged at intervals along the axial direction of the feeding shaft 411 and are all connected to the feeding shaft 411. The output end of the feeding drive assembly 42 is connected to the feeding shaft 411 to drive the feeding assembly 41 to rotate. When the feeding drive assembly 42 is working, it can drive the feeding shaft 411 to rotate, thereby driving the multiple feeding rods 412 to rotate, so as to rotate and disperse the material on the first transmission mechanism 10, preventing the material from clumping together and falling onto the second transmission mechanism 20, thereby avoiding uneven mixing of the material and improving the quality of the finished cigarettes.

[0063] In this embodiment, the rotation direction of the feeding shaft 411 is opposite to the transmission direction of the first transmission mechanism 10, so that when the feeding shaft 411 rotates, it can evenly disperse the material on the first transmission mechanism 10 and throw it in the opposite direction. In actual operation, the rotation speed of the feeding shaft 411 can be set to be much greater than the transmission speed of the first transmission mechanism 10 to ensure that the material is quickly, evenly, and repeatedly fed.

[0064] Specifically, the feeding drive assembly 42 includes a reducer 421 and a drive motor 422. Both the reducer 421 and the drive motor 422 are mounted on the housing 30, and the output end of the drive motor 422 is connected to the input end of the reducer 421. The output end of the reducer 421 is connected to the feeding shaft 411, thereby realizing the stable rotation of the feeding shaft 411.

[0065] Optionally, both ends of the feeding shaft 411 are rotatably connected to the cover 30 via bearings, thereby ensuring the stability of the feeding shaft 411 during rotation relative to the cover 30.

[0066] To achieve a fixed connection between the feeding shaft 411 and the multiple feeding rods 412, the feeding shaft 411 is provided with multiple through holes 4110 arranged at intervals along its axial direction, and the feeding rods 412 are correspondingly inserted into the through holes 4110. In this embodiment, the outer periphery of the feeding rod 412 is provided with external threads. After the feeding rod 412 is inserted into the corresponding through hole 4110, a fastening nut 413 is screwed onto both ends of the feeding rod 412 through the through hole 4110, thereby achieving a stable connection between the feeding rod 412 and the feeding shaft 411.

[0067] Optionally, the axes of the multiple through holes 4110 are not all parallel. That is, the multiple distributing rods 412 are staggered on the feeding shaft 411, so that during one rotation of the feeding shaft 411, the material on the first conveying mechanism 10 can be agitated multiple times at a high frequency, further ensuring the uniformity of tobacco mixing and guaranteeing the quality of the finished cigarettes. For example, as... Figure 6 As shown, the middle part of the feeding shaft 411 has a square columnar structure. The through hole 4110 includes a first through hole and a second through hole. The first through hole is opened on the first side of the feeding shaft 411 and passes through the feeding shaft 411 along the axial direction of the first through hole. The second through hole is opened on the second side of the feeding shaft 411 and passes through the feeding shaft 411 along the axial direction of the second through hole. The first side and the second side are perpendicular to each other. Of course, in other embodiments, the middle part of the feeding shaft 411 can also be a cylindrical structure. In this case, both the first through hole and the second through hole can pass through the feeding shaft 411 along the radial direction of the feeding shaft 411, and the axial direction of the first through hole and the axial direction of the second through hole are set at an angle.

[0068] In this embodiment, the diameter of the material separating rod 412 is 3mm to 8mm. This design avoids the material separating rod 412 being too thin, causing it to pass through the gaps in the material during rotation and thus failing to achieve the desired material-distributing effect; it also avoids the material separating rod 412 being too thick, causing it to push large pieces of material in one go and throw them in the opposite direction, thus failing to achieve the desired material-uniforming effect. For example, the diameter of the material separating rod 412 can be 3.5mm, 4.0mm, 4.5mm, 5.0mm, 5.5mm, 6.0mm, 7.5mm, etc. Of course, the diameter of the material separating rod 412 is not limited to the above range, and designers can adjust the diameter of the material separating rod 412 according to actual processing requirements.

[0069] In this embodiment, the spacing between two adjacent material distribution rods 412 is 40mm to 60mm. This design ensures that all materials on the first conveying mechanism 10 are moved, preventing large pieces of material from falling directly onto the second conveying mechanism 20 without being moved between adjacent material distribution rods 412. For example, the spacing between two adjacent material distribution rods 412 can be 42mm, 44mm, 45mm, 46mm, 48mm, 50mm, 52mm, 54mm, 55mm, 56mm, 58mm, etc. Of course, the spacing between two adjacent material distribution rods 412 is not limited to the above ranges, and designers can adjust the spacing between two adjacent material distribution rods 412 according to actual processing requirements.

[0070] In this embodiment, the distance between the free end of the distributing rod 412 and the transmission surface of the first transmission mechanism 10 is 5mm to 15mm. This design ensures that the distributing rod 412 can move the material on the first transmission mechanism 10 when it rotates, and avoids interference with the transmission surface of the first transmission mechanism 10 during rotation, thereby ensuring the stability of the transmission process of the first transmission mechanism 10. For example, the distance between the free end of the distributing rod 412 and the transmission surface of the first transmission mechanism 10 can be 5.5mm, 6.0mm, 6.5mm, 7.0mm, 7.5mm, 8.0mm, 8.5mm, 9.0mm, 9.5mm, 10.0mm, 10.5mm, 11.0mm, 11.5mm, 12.0mm, 12.5mm, 13.0mm, 13.5mm, 14.0mm, 14.5mm, etc. Of course, the distance between the free end of the material distribution rod 412 and the transmission surface of the first transmission mechanism 10 is not limited to the above range, and the designer can also adjust it according to the actual processing requirements.

[0071] In this embodiment, along the direction perpendicular to the transmission direction of the first transmission mechanism 10, the distance between the two end-positioning rods 412 and the corresponding edge of the first transmission mechanism 10 is 25mm to 35mm, to avoid collision between the end-positioning rods 412 and the edge of the first transmission mechanism 10, thereby ensuring the safety of the entire filament blending and homogenizing device. For example, along the direction perpendicular to the transmission direction of the first transmission mechanism 10, the distance between the two end-positioning rods 412 and the corresponding edge of the first transmission mechanism 10 can be 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, etc. Of course, the distance between the two end-positioning rods 412 and the corresponding edge of the first transmission mechanism 10 along the direction perpendicular to the transmission direction of the first transmission mechanism 10 is not limited to the above ranges, and designers can adjust it according to actual processing requirements.

[0072] Continue as Figure 1As shown, two opposing material conveying baffles 21 are also provided on the conveying surface of the second conveying mechanism 20, forming a material conveying gap between the two baffles 21. The width of the material conveying gap gradually decreases along the conveying direction of the second conveying mechanism 20. With this arrangement, the material falling onto the second conveying mechanism 20 can pass through the material conveying gap and be gathered to the middle position of the second conveying mechanism 20. On the one hand, this effectively solves the problem of gaps, ensuring the uniformity of tobacco mixing and the quality of the finished cigarettes. On the other hand, it also concentrates the material, preventing the loss of moisture and the increased probability of breakage during transportation.

[0073] It should be noted that in this embodiment, the first transmission mechanism 10 is an electronic belt scale, and the second transmission mechanism 20 is a belt conveyor.
