Description

Technical Field

[0001] This invention relates to the field of tobacco processing technology, and in particular to a tobacco feeding device. Background Technology

[0002] During the cigarette manufacturing process, fermented tobacco needs to be treated with added flavorings, which involves evenly spraying a prepared flavoring solution onto the tobacco to improve the smoke and taste of the cigarette. The flavoring process is a key step in the tobacco processing and has a significant impact on the sensory quality of the cigarette. Therefore, the quality of the flavoring process is a crucial point in the quality control of the tobacco processing process.

[0003] Traditional tobacco flavoring processes typically involve feeding tobacco into the inside of a drum, adding flavoring through a dual-fluid nozzle, and then stirring the tobacco inside the drum using rakes or baffles to ensure even mixing of the tobacco and flavoring. However, this method not only easily causes tobacco breakage but also makes it difficult to completely disperse the tobacco, resulting in low uniformity of the applied flavoring on the tobacco surface and affecting the quality of the cigarettes. Summary of the Invention

[0004] The purpose of this invention is to provide a tobacco feeding device that is simple to operate and highly practical. It can reduce the tobacco breakage rate while achieving uniform feeding of tobacco, solving the problems of high tobacco breakage rate and poor feeding uniformity in existing feeding processes. This effectively improves the tobacco feeding effect and ensures the quality of cigarettes.

One end of the working cylinder is provided with a feed inlet, and the inner wall of the working cylinder is provided with drive bars distributed in a spiral shape. Several feeding parts are provided inside the working cylinder near the feed inlet.

[0006] The feeding section includes a first feeding component and a second feeding component. The distance between the first feeding component and the end of the working cylinder away from the feed inlet is greater than the distance between the second feeding component and the end of the working cylinder away from the feed inlet. The position of the second feeding component in the vertical direction is higher than the position of the first feeding component in the vertical direction. A dropping channel is formed between the first feeding component and the second feeding component.

[0007] Furthermore, the working cylinder has a conical structure, one end of the working cylinder is a flared end, the flared end is covered with a sealing plate, the sealing plate is provided with a feed port that communicates with the interior of the working cylinder, and the other end of the working cylinder is a constricted end.

[0009] Furthermore, the end of the support plate near the constricted end forms a support angle with the horizontal plane, and the bottom of the end of the support plate near the flared end is provided with an adjustment component for adjusting the size of the support angle.

[0010] Furthermore, the height of the drive bar protruding from the inner wall of the working cylinder gradually increases from the flared end to the constricted end, and the pitch of the drive bar gradually increases from the flared end to the constricted end.

[0011] Furthermore, the first feeding assembly includes a first conveying pipe, one end of which penetrates the sealing plate and is connected to a first nozzle;

[0012] The second feeding assembly includes a second conveying pipe, one end of which passes through the sealing plate and is connected to a second nozzle.

[0013] Furthermore, the first feeding assembly includes a first conveying pipe, one end of which passes through the sealing plate and is connected to a first nozzle frame, the first nozzle frame being provided with a plurality of first nozzles spaced apart along its length.

[0014] The second feeding assembly includes a second conveying pipe, one end of which passes through the sealing plate and is connected to a second nozzle frame. The second nozzle frame is provided with a plurality of second nozzles spaced apart along its length.

[0015] Furthermore, a pressure sensor is provided on the first or second conveying pipe, and an infrared sensor is provided on the second nozzle frame. The pressure sensor, the infrared sensor, the conveying assembly, and the negative pressure assembly are all connected to the PLC controller.

[0016] Furthermore, the first feeding assembly includes a first conveying pipe, one end of which passes through the sealing plate and is connected to a first nozzle frame.

[0020] The beneficial effects of this invention are:

[0021] The technical solution of this invention uses a drive component to rotate the working cylinder, causing the drive strip to rotate along with the working cylinder. This causes the tobacco to rise and then fall inside the working cylinder in a spiral motion from the flared end to the constricted end, thereby loosening the tobacco. Simultaneously, during the rising and falling of the tobacco, the first and second feeding components respectively perform feeding operations on the tobacco, achieving uniform feeding of the tobacco. The damage to the tobacco is low throughout the process, solving the problems of high tobacco breakage rate and poor feeding uniformity in existing feeding processes. This effectively improves the tobacco feeding effect and ensures the quality of cigarettes. Attached Figure Description

[0036] Example 1

[0037] Depend on Figures 1 to 4 As shown, a tobacco feeding device includes a support plate 1, a conveying component 4 on one side of the support plate 1, a negative pressure component on the other side of the support plate 1, and a working cylinder 2 on the top of the support plate 1. The working cylinder 2 has a conical structure. The end of the working cylinder 2 near the conveying component 4 is a flared end 12, which is covered by a sealing plate 5. The sealing plate 5 has a feed inlet 19 that communicates with the interior of the working cylinder 2. One end of the conveying component 4 extends into the interior of the working cylinder 2 from the feed inlet 19. The end of the working cylinder 2 near the negative pressure component is a constricted end 13, which is connected to the negative pressure component through a negative pressure pipe 3.

[0038] A first guide ring 6 is fitted on the outer side of the working cylinder 2 near the flared end 12, and a second guide ring 7 is fitted on the outer side of the working cylinder 2 near the constricted end 13. The working cylinder 2 is rotatably connected to the first guide ring 6 and the second guide ring 7 respectively. A fixing block 8 is provided on the top of the support plate 1 at the position corresponding to the first guide ring 6 and the second guide ring 7. The first guide ring 6 and the second guide ring 7 are respectively connected to their corresponding fixing blocks 8. A drive motor 10 is provided on the top of the support plate 1. A gear 11 is connected to the output end of the drive motor 10. A toothed ring 9 that meshes with the gear 11 is fitted on the outer side of the working cylinder 2 between the first guide ring 6 and the second guide ring 7.

[0039] The inner wall of the working cylinder 2 is provided with several protruding drive bars 14. The drive bars 14 are spirally distributed from the flared end 12 to the constricted end 13. The height of the drive bars 14 protruding from the inner wall of the working cylinder 2 gradually increases from the flared end 12 to the constricted end 13. The pitch of the drive bars 14 gradually increases from the flared end 12 to the constricted end 13. The height of the drive bars 14 located at the constricted end 13 protruding from the inner wall of the working cylinder 2 is 0.9-1.0 times the inner diameter of the constricted end 13.

[0040] The working cylinder 2 has a feeding section located near the flared end 12. The feeding section includes a first feeding component and a second feeding component. The first feeding component includes a first conveying pipe 15, one end of which passes through the sealing plate 5 and is connected to a first nozzle 16. The second feeding component includes a second conveying pipe 17, one end of which passes through the sealing plate 5 and is connected to a second nozzle 18. The distance between the first feeding component and the constricted end 13 is 30cm greater than the distance between the second feeding component and the constricted end 13. The vertical position of the second feeding component is higher than that of the first feeding component. A throwing channel is formed between the first feeding component and the second feeding component.

[0041] The tobacco is conveyed into the working cylinder 2 by the conveying component 4, and the gear 11 is driven to rotate by the drive motor 10. The meshing of the gear 11 and the gear ring 9 drives the gear ring 9 to rotate, thereby driving the working cylinder 2 to rotate. The drive bar 14 rotates along with the working cylinder 2, causing the tobacco to rise and fall first inside the working cylinder 2, moving in a spiral from the flared end 12 to the constricted end 13, thus loosening the tobacco. At the same time, the tobacco is fed through the first nozzle 16 during the rising process. When the tobacco reaches a certain height and is thrown down, it passes through the throwing channel during the falling process. At this time, the tobacco is fed through the second nozzle 18, which achieves uniform feeding of the tobacco and low damage to the tobacco throughout the process. This solves the problems of high tobacco breakage rate and poor feeding uniformity in the existing feeding process, effectively improves the tobacco feeding effect, and ensures the quality of cigarettes.

[0042] During the tobacco feeding process, a negative pressure component is used to evacuate the interior of the working cylinder 2, thereby continuously updating the internal environment and improving its working condition. Any negative pressure component capable of evacuating the working cylinder 2, such as a centrifugal fan, is acceptable; strict limitations are not imposed. Simultaneously, the drive bar 14 is designed to be as closed as possible at the constricted end 13. This reduces the probability of air being directly extracted from the working cylinder 2, ensuring that the air passes through the tobacco before being extracted, increasing the efficiency of air intake. The opportunity for the spices in the gas to come into contact with the tobacco further enhances the feeding effect on the tobacco. On the other hand, it can also avoid the situation where the tobacco is directly drawn out of the working cylinder 2. Since the drive bar 14 protrudes a large height from the inner wall of the working cylinder 2 at the constricted end 13, in order to ensure the driving effect of the drive bar 14, the pitch of the drive bar 14 is gradually increased from the flared end 12 to the constricted end 13. For example, the pitch of the drive bar 14 at the flared end 12 is one-quarter of the height of the working cylinder 2, while the pitch of the drive bar 14 at the constricted end 13 is one-half of the height of the working cylinder 2.

[0043] In addition, by covering the flared end 12 with a sealing plate 5, the working cylinder 2 is sealed as much as possible, which can ensure the feeding effect of tobacco to a certain extent. The sealing plate 5 can also support the first feeding component and the second feeding component. At the same time, the position of the feed inlet 19 needs to correspond to the position of the first feeding component. Otherwise, the first feeding component will miss the tobacco and cannot complete the feeding process. When there are multiple feeding parts, the multiple feeding parts are arranged at intervals from the flared end 12 to the constricted end 13 to facilitate the repeated feeding operation of tobacco. At the same time, when feeding tobacco, the flavoring inside the first conveying pipe 15 and the second conveying pipe 17 can be gaseous, liquid or solid. The working mode of the first nozzle 16 and the second nozzle 18 can be high-pressure gas forming jet or ultrasonic transducer generating jet, etc., without strict limitations.

[0044] In addition, since the production speed or tobacco processing method may be adjusted as needed in practical applications, if the positions of the first and second feeding components remain fixed, it will not meet the actual requirements. For example, if it is necessary to uniformly mix the tobacco to a certain extent before feeding, the first and second feeding components need to be moved towards the constricted end 13. Or, when the rotation speed of the working cylinder 2 changes, the height at which the tobacco is thrown also changes, requiring the first and second feeding components to be adjusted in the height direction to achieve a suitable feeding time. Therefore, in other embodiments, the first... The vertical height of the first feeding pipe 15 and the second feeding pipe 17, the position along the length of the working cylinder 2, and the position along the width of the working cylinder 2 are all adjustable, so as to change the relative positional relationship between the first feeding component and the second feeding component and the working cylinder 2, thereby improving the practicality of the tobacco feeding device. However, the position of the first nozzle 16 should be as close as possible to the second nozzle 18, and the distance between the first nozzle 16 and the axis of the working cylinder 2 should be greater than the distance between the second nozzle 18 and the axis of the working cylinder 2, so that a falling channel is formed between the first feeding component and the second feeding component, ensuring that the tobacco will not fall onto the second feeding component when it descends.

[0045] The end of the support plate 1 near the constricted end 13 forms a support angle with the horizontal plane, and the bottom of the end of the support plate 1 near the flared end 12 is provided with an adjustment component for adjusting the size of the support angle.

[0046] With the rotational speed of the working cylinder 2 remaining constant, the tilt angle of the working cylinder 2 directly affects the time it takes for the tobacco to pass through the working cylinder 2. For example, if the tobacco needs to be mixed for a relatively long time, the tilt angle of the working cylinder 2 needs to be adjusted upwards. An adjustment component is set at the bottom of the support plate 1 near the flared end 12. When it is necessary to adjust the tilt angle of the working cylinder 2, the end of the support plate 1 near the constricted end 13 is hinged to the external fixed structure. The tilt angle of the working cylinder 2 can be adjusted by controlling the adjustment component. The adjustment component only needs to be able to lift and lower the support plate 1, such as a hydraulic device, etc. There are no strict limitations here. It should be noted that the change of the tilt angle of the working cylinder 2 will not have a significant impact on the position where the tobacco is thrown. Therefore, there is no need to adjust the position of the first feeding component and the second feeding component.

[0047] Example 2

[0048] Depend on Figures 5 to 6 As shown, a tobacco feeding device has a structure that is basically the same as that of Embodiment 1, except that: the first conveying pipe 15 is connected to a first nozzle frame 20 at one end through the sealing plate 5. The first nozzle frame 20 has an arc-shaped structure, and the arc of the first nozzle frame 20 is adapted to the arc of the inner wall of the working cylinder 2. The first nozzle frame 20 is provided with a plurality of first nozzles 16 spaced apart along its length. A pressure sensor 21 is provided on the outside of the first conveying pipe 15 and inside the working cylinder 2. The second conveying pipe 17 is connected to a second nozzle frame 22 at one end through the sealing plate 5. The second nozzle frame 22 has an arc-shaped structure. The second nozzle frame 22 is provided with a plurality of second nozzles 18 spaced apart along its length. An infrared sensor 23 is provided in the middle of the second nozzle frame 22. The pressure sensor 21, the infrared sensor 23, the conveying component 4, and the negative pressure component are all connected to the PLC controller.

[0049] During the ascent of the tobacco, the first nozzle 16 on the first nozzle frame 20 is used to feed the tobacco. The first nozzle frame 20 is set into an arc-shaped structure that is compatible with the inner wall of the working cylinder 2, so that the distance between the first nozzle 16 and the tobacco is as equal as possible, thereby improving the spraying effect on the tobacco. At the same time, since the tobacco forms a parabola during descent, the second nozzle frame 22 is set into an arc shape, so that the distance between the second nozzle 18 and the tobacco is as equal as possible, thereby improving the spraying effect on the tobacco. When the trend of the second nozzle frame 22 is consistent with the trend of the tobacco's downward trajectory, the working state of the second nozzle 18 can reach its optimal state.

[0050] Furthermore, by installing a pressure sensor 21 inside the working cylinder 2, the pressure data inside the working cylinder 2 is obtained and transmitted to the PLC controller. The PLC controller controls the operation of the negative pressure component based on the pressure data. If the pressure data is too low, the working intensity of the negative pressure component is reduced by the PLC controller; if the pressure data is too high, the working intensity of the negative pressure component is increased by the PLC controller. At the same time, since the tobacco should be thrown below the second nozzle frame 22 during the rotation of the working cylinder 2, an infrared sensor 23 is installed on the second nozzle frame 22 to monitor whether the tobacco is thrown correctly. When the tobacco is thrown abnormally, the infrared sensor 23 sends a signal to the PLC controller, which controls the conveying component 4 to stop working and issues a warning signal to alert the staff. In other embodiments, a camera and AI image analysis can also be used to determine whether the tobacco passes through the throwing channel normally, and the camera signal can also be transmitted to the staff's monitor to meet the needs of manual monitoring. In addition, in other embodiments, an ultrasonic sensor can also be used to achieve the above monitoring function.

[0051] Example 3

[0052] Depend on Figures 7 to 8 As shown, a tobacco feeding device has a structure basically the same as that of Embodiment 1, except that: one end of the first conveying pipe 15 passing through the sealing plate 5 is connected to a first nozzle frame 20. The first nozzle frame 20 has an arc-shaped structure, and the arc of the first nozzle frame 20 is adapted to the arc of the inner wall of the working cylinder 2. The first nozzle frame 20 is provided with a plurality of first nozzles 16 spaced apart along its length. The first conveying pipe 15 is provided with a first baffle 24, which is located above the first nozzle frame 20. The side of the first baffle 24 away from the first conveying pipe 15 is inclined downward. A pressure sensor 21 is provided on the outside of the conveying pipe 15 and inside the working cylinder 2. One end of the second conveying pipe 17, which passes through the sealing plate 5, is connected to a second nozzle frame 22. The second nozzle frame 22 has an arc-shaped structure and is provided with several second nozzles 18 spaced apart along its length. A second baffle 25 is provided on the second conveying pipe 17 and is located above the second nozzle frame 22. A mass sensor 26 is provided on the top of the second baffle 25. The pressure sensor 21, the mass sensor 26, the conveying assembly 4, and the negative pressure assembly are all connected to the PLC controller.

[0053] During the descent of tobacco, abnormal accumulation can easily occur on the first feeding component. By setting a first baffle 24 on the first conveying pipe 15, the first feeding component can be blocked. At the same time, the side of the first baffle 24 away from the first conveying pipe 15 is tilted downward, allowing the tobacco falling on the top of the first baffle 24 to slide down the slope, avoiding abnormal accumulation of tobacco. Meanwhile, by setting a second baffle 25 on the second conveying pipe 17 and setting a mass sensor 26 on the top of the second baffle 25, the mass sensor 26 can determine the state of the tobacco being thrown. For example, if the point where the tobacco is thrown is too high, the tobacco will no longer pass under the second nozzle frame 22, but will pass above the second nozzle frame 22 and fall to the top of the second baffle 25. At this time, the mass sensor 26 sends a signal to the PLC controller, which serves as a reminder to the operator. In other embodiments, an infrared sensor can also be used to determine the state of the tobacco being thrown.

[0054] In addition, in other embodiments, the center of the sealing plate 5 can be aligned with the axis of the working cylinder 2, so that the first conveying pipe 15 is located at the center of the sealing plate 5, and the first conveying pipe 15 is rotatably connected to the sealing plate 5. By rotating the first conveying pipe 15, the curvature of the first nozzle frame 20 is always matched with the curvature of the inner wall of the working cylinder 2, thereby avoiding abnormal accumulation on the first nozzle frame 20 when tobacco is thrown down.

[0055] Working principle: The tobacco is conveyed into the working cylinder 2 by the conveying component 4, and the drive motor 10 drives the gear 11 to rotate. The meshing of the gear 11 and the gear ring 9 drives the gear ring 9 to rotate, thereby driving the working cylinder 2 to rotate. The drive bar 14 rotates along with the working cylinder 2, causing the tobacco to rise and fall first inside the working cylinder 2, moving in a spiral from the flared end 12 to the constricted end 13, thus loosening the tobacco. During the tobacco rising, the first nozzle 16 feeds the tobacco. When the tobacco reaches a certain height and is thrown down, it passes through the throwing channel during its descent. At this time, the second nozzle 18 feeds the tobacco. At the same time, during the tobacco feeding process, the negative pressure component evacuates the air inside the working cylinder 2.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
