Description

Technical Field

[0001] This application relates to the field of tobacco equipment technology, and in particular to a cigarette tobacco processing apparatus. Background Technology

[0002] With the development of cigarette manufacturing technology, the size requirements for tobacco shreds are becoming increasingly stringent. Currently, tobacco leaves are shredded using appropriate processing equipment to obtain tobacco shreds (small leaves with a size of approximately 1mm-3mm) that meet production standards. However, in actual operation, because the blades of the processing equipment cannot fully contact all tobacco leaves to cut them, larger leaves that are not fully cut are produced after the first processing. These larger leaves need to be shredded again to obtain the standard small leaves (i.e., tobacco shreds). In addition, tobacco leaves need to be fed with a flavoring liquid through a feeding machine to obtain tobacco shreds that meet production requirements.

[0003] In related technologies, smaller tobacco leaves are prone to sticking to the feeder, leading to waste and an increase in yellow-stained tobacco. The production process requires manual sorting of the cut tobacco leaves according to size. Larger leaves are fed into the feeder with added molten material for secondary processing and crushing, resulting in smaller leaves mixed with the molten material. Smaller leaves obtained from the first processing step are skipped and mixed with the molten material in subsequent steps, ultimately yielding tobacco leaves that are mixed with the molten material and meet the size requirements.

[0004] However, while the manual screening method described above can effectively prevent the blades from sticking to the cylinder, the manual operation is time-consuming and labor-intensive, which greatly reduces production efficiency. Utility Model Content

[0005] Therefore, it is necessary to provide a cigarette tobacco processing device to address the problems of time-consuming, labor-intensive, and inefficient manual operation.

[0006] A cigarette tobacco processing apparatus, comprising:

[0007] The screening assembly includes a first screen, a second screen, and a third screen arranged at intervals along a predetermined direction, wherein the aperture of the first screen, the second screen, and the third screen decreases sequentially.

[0008] The assembly includes a liquid adding component, a shredding component, and a first conveying component. The first conveying component is disposed between the first screen and the shredding component and is used to convey material from the first screen to the liquid adding component and to convey the material from the liquid adding component to the shredding component.

[0009] A second conveying assembly is disposed between the second screen and the shredding assembly, and is used to convey the material from the second screen to the shredding assembly;

[0010] Output components;

[0011] A third conveying assembly is disposed between the third screen and the output assembly, and is used to convey the material from the third screen to the output assembly;

[0012] A fourth conveying component is disposed between the shredding component and the output component, and is used to convey the material at the shredding component to the output component.

[0013] In some embodiments, the aperture of the first screen is 6mm-7mm, the aperture of the second screen is 3mm-4mm, and the aperture of the third screen is 0.5mm-1mm.

[0014] In some embodiments, the screening assembly includes a vibration mechanism, to which the first screen, the second screen, and the third screen are all connected.

[0015] In some embodiments, the cigarette tobacco processing apparatus further includes a first feeding mechanism, wherein the first conveying assembly is used to convey the material from the liquid adding assembly to the first feeding mechanism; a second conveying assembly is used to convey the material from the second screen to the first feeding mechanism; and it also includes one of the following options:

[0016] The first conveying assembly or the second conveying assembly conveys the material from the first feeding mechanism to the shredding assembly;

[0017] The first conveying component and the second conveying component respectively convey the material from the first feeding mechanism to the shredding component.

[0018] In some embodiments, the cigarette tobacco processing apparatus further includes a material storage component connected to the first feeding mechanism, the material storage component being able to mutually transport the material with the first feeding mechanism.

[0019] In some embodiments, the output component includes a second feeding mechanism, the fourth conveying component is used to convey the material from the shredding component to the second feeding mechanism, and the third conveying component is used to convey the material from the third screen to the second feeding mechanism.

[0020] In some embodiments, the output component further includes a drying mechanism located at the output end of the second feeding mechanism and used to process the material processed by the second feeding mechanism.

[0021] In some embodiments, the output component further includes a stirring mechanism disposed between the second feeding mechanism and the drying mechanism.

[0022] In some embodiments, the first screen, the second screen, and the third screen are all made of stainless steel.

[0023] In some embodiments, the first conveying assembly, the second conveying assembly, and the third conveying assembly are all U-shaped belts.

[0024] In the aforementioned cigarette tobacco processing device, the first, second, and third screens are arranged in parallel. A screening component divides the material (i.e., tobacco leaves) into three parts according to size. The first screen has the largest opening size, screening out large leaves that can enter the liquid filling component. The second screen screens out smaller leaves that might stick to the liquid filling component but require secondary processing. The third screen screens out small leaves that meet the required standards. The large leaves screened by the first screen are transported to the liquid filling component via the first conveyor component. After adding liquid, they move to the cutting component under the drive of the first conveyor component. The leaves screened by the second screen are directly conveyed to the cutting component via the second conveyor component. The cutting component cuts and crushes the leaves brought by the first and second conveyor components to obtain smaller leaves. The smaller leaves are then conveyed to the output component via the fourth conveyor component. The smaller leaves screened by the third screen are conveyed to the output component via the third conveyor component and are sent out together with the smaller leaves processed by the cutting component. With the above settings, materials can be automatically separated according to size and processed separately to prevent small-sized leaves from sticking to the cylinder and to cut them into small-sized leaves (i.e. tobacco shreds) that meet production requirements. The operation is simple and convenient, requires no manual operation, and effectively improves production efficiency. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] See Figure 1 and Figure 2 , Figure 1 This is a top view schematic diagram of the overall structure of a cigarette tobacco processing apparatus according to an embodiment of this application. Figure 2 The following is a structural side view of the screening component 100 according to an embodiment of this application. It should be noted that... Figure 1The portions of the conveyor belts shown in the diagram only indicate the conveying direction of each conveyor belt and do not represent the specific structure. An embodiment of this application provides a cigarette tobacco processing device, including a screening component 100, a liquid adding component 200, a cutting component 300, a first conveying component 400, a second conveying component 500, a third conveying component 600, a fourth conveying component 700, and an output component 800. The screening component 100 includes a first screen 110, a second screen 120, and a third screen 130 arranged sequentially and at intervals along a predetermined direction, with the aperture diameter of the first screen 110, second screen 120, and third screen 130 decreasing sequentially. The first conveying component 400 is disposed between the first screen 110 and the cutting component 300 and is used to convey materials from... The first screen 110 is used to convey materials to the liquid adding assembly 200 and to convey materials from the liquid adding assembly 200 to the shredding assembly 300; the second conveying assembly 500 is disposed between the second screen 120 and the shredding assembly 300 and is used to convey materials from the second screen 120 to the shredding assembly 300; the third conveying assembly 600 is disposed between the third screen 130 and the output assembly 800 and is used to convey materials from the third screen 130 to the output assembly 800; the fourth conveying assembly 700 is disposed between the shredding assembly 300 and the output assembly 800 and is used to convey materials from the shredding assembly 300 to the output assembly 800.

[0036] It should be noted that the predetermined direction in this application can be vertical, meaning that the first screen 110, the second screen 120, and the third screen 130 are arranged alternately along the vertical direction. In some embodiments, the predetermined direction can also be at a certain angle to the vertical direction, so that the first screen 110, the second screen 120, and the third screen 130 are all inclined, as long as it is ensured that the material on the upper screen can fall onto the lower screen. Material smaller than the screen aperture falls through the screen aperture onto the lower screen under the action of gravity, thereby dividing the material into three parts according to size, thus achieving material screening.

[0037] In some implementations, the apertures of the first screen 110, the second screen 120, and the third screen 130 can be reasonably set according to actual production needs, thereby separating the material into different types. For example, the material remaining on the first screen 110 after the screening operation is large-sized tobacco leaves that do not meet production requirements and need further cutting. Due to their large size, they will not stick to the drum during the addition of slurry. The material remaining on the second screen 120 is medium-sized tobacco leaves that need further cutting, but will stick to the drum when slurry is added. The material remaining on the third screen 130 is small-sized tobacco shreds that meet production requirements.

[0038] The first conveying assembly 400, the second conveying assembly 500, the third conveying assembly 600, and the fourth conveying assembly 700 may use conveyor belts to achieve the conveying function. It should be noted that the conveyor belts in the first conveying assembly 400, the second conveying assembly 500, the third conveying assembly 600, and the fourth conveying assembly 700 may be a single section or multiple sections, as long as they meet the function of conveying materials. The specific selection can be made according to the equipment being used.

[0039] See Figure 1 and Figure 2 Preferably, along the material movement direction, the first screen 110, the first conveying assembly 400, the liquid adding assembly 200, and the shredding assembly 300 are arranged sequentially. The first conveying assembly 400 conveys the material remaining on the first screen 110 to the liquid adding assembly 200, where it adds a flavor-enhancing liquid. The material, after adding the liquid, enters the shredding assembly 300 under the influence of the first conveying assembly 400 for shredding, thus breaking larger tobacco leaves into smaller shreds to meet production requirements. Along the material movement direction, the second screen 120, the second conveying assembly 500, and the shredding assembly 300 are arranged sequentially. The material remaining on the second screen 120 enters the shredding assembly 300 under the influence of the second conveying assembly 500 for shredding. The material processed by the shredding assembly 300 is then conveyed by the fourth conveying assembly 700 to the output assembly 800 for subsequent processes to complete cigarette processing. The material remaining on the third screen 130 is directly conveyed to the output component 800 through the third conveying component 600, and is then output together with the material processed by the shredding component 300.

[0040] When this cigarette tobacco processing device is in operation, the material after one round of shredding is placed on the first screen 110 of the screening component 100. Material smaller than the aperture of the first screen 110 falls onto the second screen 120, and material smaller than the aperture of the second screen 120 falls onto the third screen 130. The material remaining on the first screen 110 after screening is conveyed to the liquid addition component 200 via the first conveying component 400 to add liquid. The material after adding liquid is then conveyed to the shredding component 300 via the first conveying component 400 for shredding. The material remaining on the second screen 120 after screening is directly conveyed to the shredding component 300 via the second conveying component 500 for shredding. The material remaining on the second screen 120 after screening does not pass through the liquid addition component 200. The material processed by the shredding component 300 is conveyed to the output component 800 via the fourth conveying component 700 for subsequent processing. The material remaining on the third screen 130 after screening is directly conveyed to the output component 800 through the third conveying component 600, and is conveyed to the outside along with the material processed by the shredding component 300. The material remaining on the third screen 130 after screening does not pass through the liquid addition component 200 and the shredding component 300.

[0041] With the above setup, the material is screened according to its size, and the screened material is transported to different components by different conveyor belts for processing. This allows for the addition of liquid material to the material without preventing small tobacco leaves from sticking to the drum, ultimately obtaining small tobacco shreds that meet production requirements. Moreover, the above process requires no manual operation, which can effectively improve production efficiency and save time and labor.

[0042] In addition, in some preferred embodiments, the liquid addition component 200 is a liquid sprayer, and the shredding component 300 is a tobacco shredding machine.

[0043] In some embodiments, the aperture of the first screen 110 is 6mm-7mm, the aperture of the second screen 120 is 3mm-4mm, and the aperture of the third screen 130 is 0.5mm-1mm.

[0044] The first screen 110 can have a screen aperture of 6mm, 6.5mm, or 7mm; the second screen 120 can have a screen aperture of 3mm, 3.5mm, or 4mm; and the third screen 130 can have a screen aperture of 0.5mm or 1mm, thereby screening the material to obtain materials between different sizes. (See also...) Figure 2 and Figure 3Preferably, the first screen 110 has a screen aperture of 6mm, and the material size remaining on the first screen 110 after the sieving operation is greater than 6mm. The second screen 120 has a screen aperture of 3mm, and the material size remaining on the second screen 120 after the sieving operation is between 3mm and 6mm. The third screen 130 has a screen aperture of 1mm, and the material size remaining on the third screen 130 after the sieving operation is between 1mm and 3mm. Parameters obtained through routine cleaning show that large-sized tobacco leaves (greater than 6mm) do not stick to the feed cylinder during the feeding process, while small-sized tobacco leaves (less than 6mm) are prone to sticking. Therefore, the above settings allow for proper sieving of the material, preventing small-sized tobacco leaves from sticking to the feed cylinder while adding feed, ultimately obtaining small-sized tobacco shreds that meet production requirements.

[0045] Additionally, it should be noted that before entering this cigarette tobacco processing device, the material needs to undergo a shredding process, which will generate tobacco shreds smaller than 1mm in size. These shreds are too small to be made into cigarettes, so a waste collection trough is installed below the third screen 130. The tobacco shreds smaller than 1mm screened by the third screen 130 fall into the waste collection trough for collection and do not enter subsequent cigarette production steps.

[0046] In some embodiments, the screening assembly 100 includes a vibration mechanism 140, and a first screen 110, a second screen 120 and a third screen 130 are all connected to the vibration mechanism 140.

[0047] See Figure 2 and Figure 3 Preferably, the vibration mechanism 140 is connected to the first screen 110, the second screen 120, and the third screen 130, and drives the first screen 110, the second screen 120, and the third screen 130 to vibrate, causing the material on the screens to vibrate, thereby screening the material. The material moves forward under vibration and eventually falls onto the corresponding conveyor belt, completing the screening operation. Specifically, in use, the material is placed on the end of the first screen 110 away from the first conveyor assembly 400. Under the vibration of the screen, the material moves towards the first screen 110 and closer to the first conveyor assembly 400, undergoing screening during the movement. Smaller materials fall onto the second screen 120. Similarly, the material on the second screen 120 moves towards the end of the second screen 120 and closer to the second conveyor assembly 400 for screening. The material falling onto the third screen 130 also moves towards the third screen 130 and closer to the third conveyor assembly 400.

[0048] With the above setup, materials can continuously move from one end of the screen to the other, undergoing screening during the movement without requiring machine shutdown, effectively improving processing efficiency. Figure 2As shown, the vibration mechanism 140 uses three vibrating plates, which are connected to the three screens one by one to drive the screens to vibrate and achieve the above purpose.

[0049] Furthermore, the first screen 110, the second screen 120, and the third screen 130 can be inclined relative to the horizontal direction, so that the end of the screen near the conveyor belt is slightly lower than the end away from the conveyor belt. Thus, during the vibration of the screen, the material can continuously move towards the conveyor belt and fall onto the conveyor belt for transport to the corresponding processing equipment for processing.

[0050] In some embodiments, the cigarette tobacco processing apparatus further includes a first feeding mechanism 900, a first conveying assembly 400 for conveying material from the liquid adding assembly 200 to the first feeding mechanism 900; a second conveying assembly 500 for conveying material from the second screen 120 to the first feeding mechanism 900; and also includes one of the following options:

[0051] The first conveying assembly 400 or the second conveying assembly 500 conveys the material from the first feeding mechanism 900 to the shredding assembly 300;

[0052] The first conveying assembly 400 and the second conveying assembly 500 respectively convey the material from the first feeding mechanism 900 to the shredding assembly 300.

[0053] See Figure 1 Preferably, the first feeding mechanism 900 is a feeder, which controls the amount of material conveyed to the shredding assembly 300 to prevent excessive material from entering the shredding assembly 300, which would result in insufficient contact between the material and the material-cutting structure (such as blades) of the shredding assembly 300. The material processed by the liquid addition assembly 200 and the material remaining on the second screen 120 after screening are uniformly fed into the feeder. The feeder outputs material to the shredding assembly 300 according to its processing capacity (i.e., output). For example, if the material inside the shredding assembly 300 is 20 kg, it can be fully cut. If the shredding assembly 300 completes 10 kg of tobacco leaf processing per minute, then the first feeding mechanism 900 outputs 10 kg of material to the shredding assembly 300 per minute, so that the material inside the shredding assembly 300 is always at a suitable level (such as 20 kg as mentioned above), ensuring that the shredding assembly 300 can fully cut the material inside to obtain tobacco shreds that meet production standards.

[0054] It should be noted that a single conveyor belt (partial structure of the first conveyor assembly 400 or the second conveyor assembly 500) can be installed between the first feeding mechanism 900 and the shredding assembly 300 to uniformly transport materials to the shredding assembly 300. Alternatively, multiple conveyor belts can be installed to transport materials to the shredding assembly 300 separately. The key is to ensure that the total amount of material transported from the first feeding mechanism 900 to the shredding assembly 300 is less than or equal to the processing capacity of the shredding assembly 300, thus preventing excessive material accumulation within the shredding assembly 300 and affecting the shredding effect. Preferably, in this embodiment, a single conveyor belt is used to transport materials from the first feeding mechanism 900 to the shredding assembly 300.

[0055] In addition, see Figure 1 In this embodiment, preferably, the first conveying component 400 and the second conveying component 500 intersect in front of the first feeding mechanism 900, and the materials are conveyed by a conveyor belt, so as to effectively save materials and improve conveying efficiency.

[0056] In some embodiments, the cigarette tobacco processing apparatus further includes a storage component 910, which is connected to the first feeding mechanism 900 and is capable of conveying materials to each other with the first feeding mechanism 900.

[0057] See Figure 1 Preferably, the storage component 910 is a storage cabinet. The interior of the storage component 910 and the interior of the first feeding mechanism 900 are connected by a conveyor belt or pipe, allowing materials to move between the storage component 910 and the first feeding mechanism 900. During use, because the amount of material conveyed to the first feeding mechanism 900 by the liquid addition component 200 and the second screen 120 is greater than the amount conveyed to the shredding component 300 by the first feeding mechanism 900, material accumulates at the first feeding mechanism 900. When there is excessive material accumulation in the first feeding mechanism 900, the excess material can be conveyed to the storage component 910 for storage. After the material in the first feeding mechanism 900 decreases, the material stored in the storage component 910 is then conveyed to the first feeding mechanism 900 for further conveying. This ensures that the cigarette tobacco processing device will not stop due to excessive material accumulation at the first feeding mechanism 900, thus ensuring the normal operation of the device.

[0058] In addition, the material processed by the liquid addition component 200 and the material remaining in the second screen 120 after screening can be directly transported to the storage component 910 for storage. The storage component 910 supplies the material to the first feeding mechanism 900 with the processing capacity of the shredding component 300, which can also achieve the expected effect.

[0059] In some embodiments, the output component 800 includes a second feeding mechanism 810, a fourth conveying component 700 for conveying material from the shredding component 300 to the second feeding mechanism 810, and a third conveying component 600 for conveying material from the third screen 130 to the second feeding mechanism 810.

[0060] See Figure 1 Preferably, the material processed by the shredding component 300 is conveyed to the second feeding mechanism 810 via the fourth conveying component 700, and the material remaining on the third screen 130 after screening is directly conveyed to the second feeding mechanism 810 via the third conveying component 600. The second feeding mechanism 810 is used to control the output of material to facilitate subsequent operations such as packaging and cigarette manufacturing.

[0061] In some embodiments, the output component 800 further includes a drying mechanism 820, which is located at the output end of the second feeding mechanism 810 and is used to process the material processed by the second feeding mechanism 810.

[0062] See Figure 1 Preferably, the drying mechanism 820 is a dryer, and the second feeding mechanism 810 feeds the material to the drying mechanism 820 to dry the material and obtain material that can be used to make cigarettes.

[0063] In some embodiments, the output component 800 further includes a stirring mechanism (not shown) disposed between the second feeding mechanism 810 and the drying mechanism 820.

[0064] See Figure 1 Preferably, a mixer is selected as the mixing mechanism. The mixing mechanism is located at the output end of the second feeding mechanism 810 and is used to fully mix and stir the material output from the second feeding mechanism 810, so that the material that has not passed through the liquid addition component 200 (the material remaining on the second screen 120 and the third screen 130 after screening) is mixed with the material that has been processed by the liquid addition component 200, so that the liquid is evenly distributed on the tobacco shreds. After the liquid is evenly distributed on the tobacco shreds, they are dried to obtain tobacco shreds that meet the production requirements.

[0065] Furthermore, the mixing mechanism can be replaced by a second feeding mechanism 810 with a mixing function. With the above configuration, the second feeding mechanism 810 can complete the functions of mixing and conveying materials, reducing the floor space and simplifying the structure.

[0066] In some embodiments, the first screen 110, the second screen 120, and the third screen 130 are all made of stainless steel.

[0067] See Figure 2Preferably, the first screen 110, the second screen 120, and the third screen 130 are all made of stainless steel to ensure a certain strength, prevent the first screen 110, the second screen 120, and the third screen 130 from breaking during the screening process, and prevent the screens from rusting, thus avoiding the tobacco from sticking to rust and affecting the taste of the cigarettes.

[0068] In some embodiments, the first conveying assembly 400, the second conveying assembly 500, and the third conveying assembly 600 are all U-shaped belts.

[0069] Preferably, the first conveying component 400, the second conveying component 500 and the third conveying component 600 are all made of U-shaped belts to reduce material falling during material transportation.

[0070] 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.

[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively 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 protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
