[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0027] In some embodiments of the tobacco wind selection device provided by the utility model, the tobacco wind selection device includes a wind selection device, a first detection device and an adjustment device, and the wind selection device is configured to wind select the tobacco material. Figure 1 As shown, the air selection device includes an air selection device body 1 and a fan 2, the fan 2 is configured to drive air to flow in the air selection device body 1 to separate tobacco and debris in the tobacco material; the first detection device is configured to detect the content of tobacco in the debris obtained after the tobacco material is air-selected; the adjustment device is signal-connected to the first detection device, and the adjustment device is configured to adjust the wind speed of the fan 2 according to the detection result of the first detection device.

[0028] Among them, air separation mainly uses controllable airflow as the medium, and uses airflow at a certain speed to separate different components (light components and heavy components) in the material. However, due to the influence of factors such as the properties of each component and the speed of the airflow, it is easy to have incomplete separation of the components, that is, heavy components are mixed in light components, or light components are mixed in heavy components.

[0029] Similarly, after the tobacco material is air-selected, there will be a phenomenon that tobacco shreds are mixed in the separated debris, which will lead to waste of tobacco shreds and reduce the output rate of tobacco shreds. Therefore, by setting up a first detection device, it is possible to detect the content of tobacco shreds in the debris obtained after the tobacco material is air-selected, and to achieve instant feedback on the separation effect of the air-selection device, and by setting up an adjustment device, the wind speed of the fan 2 can be adjusted according to the detection result of the first detection device to achieve more accurate separation and control of the debris and tobacco shreds, minimize the amount of tobacco shreds mixed in the separated debris, optimize the sorting effect of the air-selection device, and thus improve the output rate of tobacco shreds.

[0030] In the production process of cigarettes, air separation of tobacco materials is the core process in the silk making process. Usually, one or more air separation equipment is used to separate, float and float tobacco materials. Specifically, after the tobacco materials enter the first-level air separation equipment through the feeding mechanism, they are floated under the action of lateral air inlet. Since the density and wind receiving area of ​​each component of the separated material (including leaves, leaf filaments, agglomerates, tobacco stems, metals and stones, etc.) are different, the positions where each component falls under the action of lateral wind are also different. Therefore, the material can be floated by reasonably adjusting the wind speed of the lateral air inlet. However, the separation effect of floating for components with similar mass and density will be reduced; therefore, in order to further improve the separation effect, a second-level air separation device can be set up, and the material floated down by vertical air inlet is floated again. The light materials (usually leaves, leaf filaments, etc.) are selected by using the difference in suspension speed of different components in the material, and the heavy materials (agglomerates, tobacco stems, metals and stones, etc.) are discharged from the outlet of the second-level air separation device. However, due to the influence of factors such as the properties of each component and the air flow velocity during the air separation process, the material finally separated may be a mixture of light and heavy materials. For example, heavy materials are mixed in light materials, which affects the purity of the components of the cigarette product, or light materials are mixed in heavy materials, resulting in waste of tobacco materials.

[0031] Therefore, the tobacco wind selection equipment of the utility model can be used as a supplement to the original wind selection equipment. In a cigarette production line with only a single-stage wind selection equipment, the tobacco wind selection equipment of the utility model can be set after the original wind selection equipment, which is equivalent to once again wind selecting the material separated by the original wind selection equipment, thereby improving the purity of the tobacco material finally obtained, ensuring the purity of the components of the cigarette product, and reducing the waste of tobacco materials; and in a cigarette production line with a multi-stage wind selection equipment, the tobacco wind selection equipment of the utility model can be set between any two stages of the original wind selection equipment according to actual needs, so as to obtain tobacco products of different purities in different process flows, meet the production needs of different processes, or similarly set at the end of the wind selection process, so as to ensure the purity of the components of the cigarette product and reduce the waste of tobacco materials.

[0032] Through the coordinated operation of the above-mentioned air selection device, the first detection device and the adjustment device, the automated operation capability of the cigarette production line can be improved, which not only helps to reduce labor costs, but also improves production efficiency and helps to enhance the consistency and reliability of cigarette product output.

[0033] Due to the light weight of tobacco, it is easy for tobacco to adhere to the wall of the equipment during the air selection process of tobacco materials, resulting in waste of tobacco and affecting the output rate of tobacco. Figure 2As shown, in some embodiments, the air selection device body 1 includes a discharge port 11, and the discharge port 11 is used to output tobacco shreds obtained after the tobacco material is air-selected. The tobacco shreds air selection equipment also includes a second detection device 3 connected to the signal of the adjustment device. The second detection device 3 is configured to detect the amount of tobacco shreds adhered to the inner wall surface of the air selection device located at the discharge port 11. The adjustment device is configured to adjust the wind speed of the fan 2 according to the detection result of the second detection device 3.

[0034] Specifically, the wind speed of the fan 2 can be adjusted according to the specific situation of tobacco hanging on the wall. For example, when the second detection device 3 detects that tobacco is adhered to the inner wall surface at the discharge port 11, by changing relevant parameters, such as appropriately increasing the wind speed of the fan 2, that is, dynamically adjusting the wind force, so that the tobacco hanging on the wall can fall off and then be output from the discharge port 11 as the airflow flows. When there is no tobacco adhering to the inner wall surface, the wind speed of the fan 2 can be appropriately reduced to achieve energy saving.

[0035] refer to Figure 1 As shown, in some embodiments, the tobacco air selection equipment also includes a receiving plate 4 arranged below the air selection device body 1, and the impurities obtained after the tobacco material is air-selected are discharged onto the receiving plate 4 through the first discharge port 12 of the air selection device.

[0036] The surface area of ​​the receiving plate 4 for receiving the sundries can be set larger so that the sundries can be fully spread out, so as to intuitively show the tobacco shreds mixed in the sundries.

[0037] The receiving plate 4 is not limited to a plate-like structure, and can be set to a box-type, box-type structure, etc., or in some embodiments, the tobacco selection equipment also includes a collecting device, and the receiving plate 4 can be set to a structural form that is convenient for connection with the collecting device, so that after completing the image collection of the debris, the debris can be uniformly collected into the collecting device, which is convenient for unified processing of the debris.

[0038] In some embodiments, the first detection device includes an image collector and a detection unit, the image collector is configured to collect images of debris on the docking plate 4, and the detection unit is configured to process the images of the debris to obtain the content of tobacco in the debris.

[0039] Among them, conventional image processing methods can be used to process the images of the debris, for example, a method including steps of image conversion, image segmentation, feature extraction, parameter screening, etc. can be used to process the images.

[0040] refer to Figure 1As shown, in some embodiments, the air selection device body 1 includes a feed port 13, a discharge port 11, an air conveying pipe 14 and a first discharge port 12. The feed port 13 is used to introduce tobacco materials. The air conveying pipe 14 is connected to the bottom of the fan 2. The inlet and outlet of the air conveying pipe 14 are respectively connected to the feed port 13 and the discharge port 11. The first discharge port 12 is connected to the bottom of the air conveying pipe 14. Under the action of the fan 2, an airflow from bottom to top is formed in the air conveying pipe 14 to separate the tobacco materials. The shredded tobacco obtained after the separation of the tobacco materials is output from the discharge port 11, and the debris obtained after the separation of the tobacco materials is discharged from the first discharge port 12.

[0041] Under the action of the fan 2, a wind field from bottom to top is formed in the air delivery pipe 14 from the feed port 13 to the discharge port 11. By adjusting the strength of the wind field, the tobacco materials (light materials) such as shredded tobacco and leaves with lower density can be lifted up with the wind field, while the debris (heavy materials) such as metal fragments and agglomerates with higher density fall down. The shredded tobacco can be used in the subsequent cigarette making process after being discharged from the discharge port 11, and the debris can be further recycled after being discharged from the first discharge port 12 to avoid waste.

[0042] refer to Figure 1 As shown, in some embodiments, the air separation device body 1 further includes a first air separation chamber 15 connected between the air delivery pipe 14 and the fan 2, and the first air separation chamber 15 is configured to air separate the first material obtained after the tobacco material is separated.

[0043] The tobacco material may be separated inside the air delivery pipe 14 to produce some first materials with a density between tobacco shreds and debris, such as stems, clumped tobacco shreds, and a mixture of leaf stems and shreds, etc. These first materials cannot be directly discharged from the discharge port 11 along with the wind field, nor can they be directly dropped to the first discharge port 12. Therefore, by setting a first air selection bin 15 connected between the air delivery pipe 14 and the fan 2, these first materials can be further air-selected, and by adjusting the air volume, wind speed, wind direction and other parameters in the first air selection bin 15, a wind field that can effectively separate tobacco shreds and debris in the first material is obtained, thereby realizing secondary separation of tobacco materials in the air selection device.

[0044] There is also a part of the first material in the form of agglomerates, which is called the second material. These second materials cannot be separated in the first air separation bin 15, and will fall down under the action of gravity. Figure 1As shown, in some embodiments, the air separation device body 1 also includes a loosener 16, a second air separation bin 17 and a second discharge port 18. The second air separation bin 17 is arranged below the first air separation bin 15. The loosener 16 is connected between the first air separation bin 15 and the second air separation bin 17. The loosener 16 is configured to loosen the agglomerated second material obtained after air separation of the first material. The second air separation bin 17 is configured to air separate the loosened second material. The second discharge port 18 is connected to the second air separation bin 17 for outputting the debris obtained after air separation of the first material and the second material.

[0045] In the above embodiment, the shredded tobacco discharged through the discharge port 11 is mixed with the flowing airflow, which is inconvenient to collect. Figure 2 As shown, in some embodiments, the air selection device body 1 includes a discharge port 11 and an air-material separator 19, the discharge port 11 is used to output tobacco shreds obtained after air selection of the tobacco material, the air-material separator 19 is used to separate tobacco shreds and gas, and the air-material separator 19 includes an inlet connected to the discharge port 11, a first outlet for discharging tobacco shreds, and a second outlet for discharging gas.

[0046] In other embodiments, the tobacco wind selection device further includes a tobacco air lock 5, and the tobacco is discharged and collected through the gas-material separator 19 and the tobacco air lock 5. During the collection process, the second detection device 3 is used to observe whether the tobacco remains inside the gas-material separator 19 or the tobacco air lock 5. If there is a phenomenon of tobacco hanging on the wall, the relevant parameters are changed, such as dynamically adjusting the wind force of the fan 2, so as to achieve the shedding of the tobacco hanging on the wall, thereby reducing the waste of tobacco and reducing the maintenance burden of the equipment.
