[0025] With the continuous development of the tobacco processing technology, the requirements for the finished product quality of tobacco are also getting higher and higher. Improving the purity of tobacco leaves can ensure the taste of tobacco and reduce the harmful substances in tobacco.

[0026] However, tobacco often contains tiny impurities such as hemp fibers, and there is a lack of technical solutions for efficiently removing tiny impurities such as hemp fibers in the prior art.

[0027] To at least solve the problem that there is a lack of technical solutions for efficiently removing tiny impurities such as hemp fibers in the prior art, an impurity removal machine 100 is proposed in the embodiments of the present application, which can electrostatically adsorb the impurities in tobacco leaves, thereby efficiently removing tiny impurities such as hemp fibers.

[0028] The embodiments of the present application also propose an impurity removal system 1000 including the impurity removal machine 100 as described in the above embodiments.

[0029] The embodiments of the present application also propose a tobacco transmission system 10000 including the impurity removal system 1000 as described in the above embodiments.

[0030] The impurity removal machine 100, the impurity removal system 1000 and the tobacco transmission system 10000 of the embodiments of the present application will be introduced below with reference to the drawings.

[0031] Combined with Figure 1 and Figure 2As shown in the figure, the impurity removal machine 100 of the embodiment of the present application includes: a frame 10, an electrostatic adsorption device 20, a separation device 30, a collection device 40, and a driving device 50. The electrostatic adsorption device 20 is rotatably arranged on the frame 10. The electrostatic adsorption device 20 is used to cooperate with the conveyor belt 2000 for transporting tobacco leaves. The electrostatic adsorption device 20 is configured to generate static electricity by rubbing the tobacco leaves when rotating, so as to adsorb the impurities in the tobacco leaves; the separation device 30 is arranged on the frame 10. The separation device 30 is connected to the electrostatic adsorption device 20 and squeezes the electrostatic adsorption device 20 to separate the impurities adsorbed by the electrostatic adsorption device 20; the collection device 40 defines a collection chamber 41 for collecting impurities. One end of the collection chamber 41 corresponding to the separation device 30 forms an opening to be able to receive the impurities separated by the separation device 30; the driving device 50 is in transmission connection with the electrostatic adsorption device 20 to drive the electrostatic adsorption device 20 to rotate.

[0032] The electrostatic adsorption device 20 is rotatably arranged on the frame 10 and can cooperate with the conveyor belt 2000 for transporting tobacco leaves. The electrostatic adsorption device 20 generates static electricity by rotating and rubbing the tobacco leaves to adsorb impurities. Thus, by utilizing the electrostatic characteristics, it is possible to electrostatically adsorb the lighter and smaller impurities (such as hemp fibers, wood chips, etc.) in the tobacco leaves. Due to the wide range of action of electrostatic adsorption, it is possible to comprehensively capture the impurities during the transmission of tobacco leaves, improving the efficiency and effect of impurity removal, effectively reducing the content of impurities in the tobacco leaves, and enhancing the purity of the tobacco leaves.

[0033] The separation device 30 is connected to the electrostatic adsorption device 20 and squeezes the electrostatic adsorption device 20, which can reliably separate the impurities adsorbed on the electrostatic adsorption device 20. The collection device 40 defines a collection chamber 41, and one end opening of the collection chamber 41 corresponds to the separation device 30, facilitating the reception of the separated impurities, so that the impurities can be smoothly collected, and it is beneficial for the subsequent unified treatment of the impurities. The existence of the collection chamber 41 provides a space for centralized storage of the impurities, facilitating regular cleaning and improving convenience.

[0034] The frame 10, as a basic support structure, can carry the electrostatic adsorption device 20, the separation device 30, the collection device 40, and the driving device 50, so that the layout of each component is reasonable and the cooperation is close, thus having good functional synergy and being able to meet the requirements for removing impurities from tobacco leaves in actual production.

[0035] Combined Figure 1 and Figure 2 As shown in the figure, in some embodiments, the electrostatic adsorption device 20 includes an electrostatic belt 21 and a plurality of driving rollers 22. The electrostatic belt 21 extends along the width direction of the frame 10 and is sleeved on each driving roller 22. At least one driving roller 22 is in transmission connection with the driving device 50.

[0036] The static electricity belt 21 extends along the width direction of the rack 10, enabling the static electricity belt 21 to cover a large area. When the static electricity belt 21 contacts the conveyor belt 2000 for transporting tobacco leaves, it can act on the tobacco leaves within a large range. Therefore, the efficiency of removing impurities can be improved, the residual amount of impurities in the tobacco leaves can be reduced, and thus the quality and purity of the tobacco leaves can be enhanced.

[0037] At least one driving roller 22 is in transmission connection with the driving device 50, and the power provided by the driving device 50 is transmitted to the static electricity belt 21 through the driving roller 22, enabling the static electricity belt 21 to rotate at a set speed and in a set direction.

[0038] Combined Figure 1 and Figure 2 As shown, in some embodiments, the static electricity adsorption device 20 further includes a plurality of guiding members 23. The plurality of driving rollers 22 and the plurality of guiding members 23 are sequentially arranged on the rack 10 along the width direction of the rack 10. Each guiding member 23 includes a mounting plate 231, a mounting rod 232, and a guiding wheel 233. The mounting plate 231 is provided with a plurality of mounting holes, and at least one of the plurality of mounting holes is connected to the rack 10 through a threaded member. The mounting rod 232 is connected to the mounting plate 231, and the guiding wheel 233 is rotatably arranged on the mounting rod 232. The static electricity belt 21 is also sleeved on the guiding wheels 233 of each guiding member 23.

[0039] The mounting plate 231 is provided with a plurality of mounting holes, and at least one of them is connected to the rack 10 through a threaded member. When it is necessary to adjust the position of the guiding member 23, by selecting different mounting holes to be connected to the rack 10, the position of the mounting plate 231 can be adjusted, thereby the positions of the mounting rod 232 and the guiding wheel 233 can be adjusted, and further the position and shape of the static electricity belt 21 can be changed. In addition, by loosening the threaded member, the angle of the mounting plate 231 relative to the rack 10 can be adjusted, thereby the positions of the mounting rod 232 and the guiding wheel 233 can be adjusted, and further the position and shape of the static electricity belt 21 can be changed.

[0040] Thus, the applicability of the static electricity belt 21 in this embodiment can be increased, enabling the static electricity belt 21 to adapt to conveyor belts 2000 of various models.

[0041] Combined Figure 1 and Figure 2 As shown, in some embodiments, the separating device 30 includes a separating roller 31. The separating roller 31 is rotatably arranged on the rack 10. The separating roller 31 abuts against the static electricity belt 21 and squeezes the static electricity belt 21 to separate the impurities adsorbed by the static electricity belt 21.

[0042] The separating roller 31 abuts against and presses the static electricity belt 21. When the static electricity belt 21 adsorbed with sundries rotates to the position in contact with the separating roller 31, under the pressing action of the separating roller 31, the sundries can overcome the adsorption force of the static electricity belt 21, so that the sundries can be separated from the surface of the static electricity belt 21, thus realizing the function of effectively separating the sundries adsorbed by the static electricity adsorption device 20, and ensuring that the static electricity belt 21 can continuously and efficiently adsorb the sundries in the tobacco leaves.

[0043] The separating roller 31 is rotatably arranged on the frame 10. When in contact with and pressing the static electricity belt 21, the separating roller 31 can uniformly contact the static electricity belt 21, thereby reducing the wear of the separating roller 31 on the static electricity belt 21 and prolonging the service life of the static electricity belt 21.

[0044] In some other embodiments, the separating device 30 includes a scraper. The scraper is arranged on the frame 10, abuts against the static electricity belt 21, and presses the static electricity belt 21 to separate the sundries adsorbed by the static electricity belt 21.

[0045] The scraper abuts against and presses the static electricity belt 21. When the static electricity belt 21 adsorbed with sundries rotates to the position in contact with the scraper, under the pressing action of the scraper, the sundries can overcome the adsorption force of the static electricity belt 21, so that the sundries can be separated from the surface of the static electricity belt 21, thus realizing the function of effectively separating the sundries adsorbed by the static electricity adsorption device 20, and ensuring that the static electricity belt 21 can continuously and efficiently adsorb the sundries in the tobacco leaves.

[0046] Combined Figure 1 、 Figure 2 and Figure 3 As shown in

[0047] In some embodiments, the frame 10 includes a frame body 11, a bracket 12 and an adjusting assembly 13. The adjusting assembly 13 includes an adjusting shaft 131 and a plurality of locking nuts 132. The adjusting shaft 131 extends along the width direction of the frame 10. The adjusting shaft 131 penetrates through the side wall of the frame body 11. At least one locking nut 132 is located on one side of the side wall of the frame body 11 and abuts against the frame body 11. At least another locking nut 132 is located on the other side of the side wall of the frame body 11 and abuts against the frame body 11. Each locking nut 132 is threadedly connected to the adjusting shaft 131, and the adjusting shaft 131 is connected to the bracket 12.

[0048] When it is necessary to adjust the positions of the frame body 11 and the bracket 12 in the width direction of the frame 10, loosen the locking nuts 132 to release the restriction of the locking nuts 132 on the frame body 11, so that the frame body 11 and the bracket 12 can approach or move away from each other. When the adjustment of the position of the frame body 11 is completed, tighten the locking nuts 132 to fix the frame body 11.

[0048] Through the adjusting assembly 13, the size of the frame 10 in the width direction of the frame 10 can be adjusted, so that the frame 10 can be installed on conveyor belts 2000 of various size types, thereby increasing the applicability of the present application.

[0049] Combination Figure 1 , Figure 2 and Figure 4 As shown, the impurity removal system 1000 of the embodiment of the present application includes: at least two impurity removal machines 100 and material turning machines 200 as described in the above embodiments. At least one impurity removal machine 100 is located on one side of the material turning machine 200, and at least another impurity removal machine 100 is located on the other side of the material turning machine 200. The material turning machine 200 includes a housing 60, a material turning assembly 70, a material turning shaft 80 and a driving electrode. The turning assembly 70 includes a fixing member 71 and a plurality of levers 72. The fixing member 71 is mounted on the casing 60. Each lever 72 is movably connected to the fixing member 71. Each lever 72 is used to cooperate with the conveyor belt 2000 for transporting tobacco leaves to turn the tobacco leaves. The turning shaft 80 is rotatably arranged on the casing 60. The extension direction of the turning shaft 80 intersects with the extension direction of each lever 72. The turning shaft 80 is configured to move the lever 72 when it rotates to move the lever 72. The driving motor 90 is transmission-connected to the turning shaft 80 to drive the turning shaft 80 to rotate.

[0050] The turning shaft 80 of the turning machine 200 is rotatably disposed in the casing 60. When the turning shaft 80 rotates, it can drive the lever 72 to move, so that the lever 72 can turn the tobacco leaves.

[0051] The impurity remover 100 is distributed on both sides of the material turning machine 200. After the tobacco leaves are first impurity removed on one side of the material turning machine 200, the tobacco leaves are turned over by the material turning machine 200 to turn the covered or insufficiently exposed impurities to the surface, and then the tobacco leaves are secondarily impurity removed by the impurity remover 100 on the other side of the material turning machine 200, thereby effectively removing impurities from various parts of the tobacco leaves, significantly improving the purity of the tobacco leaves, and reducing the impact of impurities on subsequent processing procedures.

[0052] Combination Figure 1 and Figure 4 As shown, in some embodiments, at least a portion of the lever 72 is located on one side of the turning shaft 80 , and at least another portion of the lever 72 is located on the other side of the turning shaft 80 .

[0053] There are levers 72 on both sides of the turning shaft 80. When the turning shaft 80 rotates, it can simultaneously drive the levers 72 on both sides to turn the tobacco leaves, so that the tobacco leaves can be fully turned over and all parts of the tobacco leaves can be fully exposed, which is beneficial to subsequent impurity removal processes.

[0054] In some embodiments, each lever 72 includes a toggling section and a turning section that are interconnected. The turning section is located outside the fixing member 71, and the toggling section is movably disposed on the fixing member 71. The turning shaft 80 is configured to toggle the toggling section when rotating to drive the turning section to swing.

[0055] Each lever 72 includes a toggling section and a material turning section that are connected to each other. The toggling section is movably disposed on the fixing member 71, so that the material turning shaft 80 can accurately transmit power to the lever 72. When the material turning shaft 80 rotates, it toggles the toggling section, which can ensure the accuracy and stability of power transmission, thereby reliably driving the material turning section to swing and realizing effective material turning of the tobacco leaves.

[0056] This design combines the toggling section with the fixing member 71, making the structure of the entire material turning assembly 70 more compact.

[0057] In some alternative embodiments, the material turning shaft 80 is provided with a toggling protrusion. When the material turning shaft 80 rotates, the toggling protrusion can abut against the toggling section to toggle the toggling section.

[0058] The toggling protrusion on the material turning shaft 80 can abut against the toggling section of the lever 72. During the rotation of the material turning shaft 80, the toggling protrusion can stably transmit the rotational power of the material turning shaft 80 to the lever 72.

[0059] Combined Figure 1 、 Figure 4 and Figure 5 As shown in, in some embodiments, the material turning machine 200 further includes a first adjusting seat 110, an adjusting bolt 120, a second adjusting seat 130, a sliding plate 140, and a bearing seat 150. The first adjusting seat 110 and the second adjusting seat 130 are both disposed on the machine housing 60. The first adjusting seat 110 and the second adjusting seat 130 are spaced apart. The sliding plate 140 is slidably disposed on the second adjusting seat 130. The bearing seat 150 is disposed on the sliding plate 140. The first adjusting seat 110 is connected to the sliding plate 140 through the adjusting bolt 120. Avoidance grooves are provided on the side wall of the machine housing 60, the second adjusting seat 130, and the sliding plate 140. The material turning shaft 80 passes through the side wall of the machine housing 60, the second adjusting seat 130, and the sliding plate 140 through the avoidance grooves and is rotatably disposed in the bearing seat 150.

[0060] By providing the first adjusting seat 110, the adjusting bolt 120, and the sliding plate 140, flexible adjustment of the position of the material turning shaft 80 can be achieved. Rotating the adjusting bolt 120 can push the sliding plate 140 to slide on the second adjusting seat 130, thereby driving the bearing seat 150 and the material turning shaft 80 installed on the sliding plate 140 to move. Thus, according to different tobacco leaf processing requirements, the position of the material turning shaft 80 can be accurately adjusted to optimize the material turning effect.

[0061] Combined Figure 1 、 Figure 2 and Figure 4As shown in the figure, the tobacco transmission system 10000 of the embodiment of the present application includes: a conveyor belt 2000 and the impurity removal system 1000 of the above embodiment. The conveyor belt 2000 is used to transport tobacco. The electrostatic adsorption device 20 cooperates with the conveyor belt 2000 for transporting tobacco leaves to be able to adsorb impurities in the tobacco leaves. Each lever 72 cooperates with the conveyor belt 2000 to turn over the tobacco leaves.

[0062] The tobacco transmission system 10000 of the embodiment of the present application includes the impurity removal system 1000 of the above embodiment. The electrostatic adsorption device 20 is rotatably arranged on the frame 10 and can cooperate with the conveyor belt 2000 for transporting tobacco leaves. The electrostatic adsorption device 20 generates static electricity by rubbing against the tobacco leaves during rotation to adsorb impurities. Thus, by utilizing the electrostatic characteristics, it is possible to electrostatically adsorb relatively light and tiny impurities (such as hemp fibers, wood chips, etc.) in the tobacco leaves. Due to the relatively wide range of action of electrostatic adsorption, it is possible to comprehensively capture impurities during the transmission of tobacco leaves, improving the efficiency and effect of impurity removal, effectively reducing the content of impurities in the tobacco leaves, and enhancing the purity of the tobacco leaves. The impurity removal machines 100 are distributed on both sides of the turning machine 200. After the first impurity removal on one side of the turning machine 200, the turning machine 200 turns over the tobacco leaves to turn the impurities that are covered or not fully exposed to the surface, and then the tobacco leaves pass through the impurity removal machine 100 on the other side of the turning machine 200 for secondary impurity removal, so as to effectively remove impurities in all parts of the tobacco leaves, significantly improve the purity of the tobacco leaves, and reduce the impact of impurities on subsequent processing procedures.
