Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a uniform feeding device for tobacco shredding. Background Technology

[0002] The tobacco processing uniform feeding device is a piece of equipment on the tobacco processing production line used to achieve uniform addition of slurry. It can precisely control the feeding amount for tobacco leaves of different specifications, ensuring even distribution of the slurry on the surface of the leaves and guaranteeing consistent quality in subsequent processing. This device is easy to operate and can work in conjunction with other equipment on the tobacco processing production line. It plays a crucial role in improving the uniformity of tobacco feeding and stabilizing the quality of tobacco products, making it one of the key pieces of equipment in the tobacco processing technology to ensure precise and efficient feeding.

[0003] When the tobacco processing uniform feeding device is working, tobacco leaves enter the feeding area via a conveyor, and the molten material is pumped to the atomizing nozzle. Through air pressure and pressure regulation, the molten material is atomized into fine droplets. At the same time, the control system adjusts the feeding amount in real time according to parameters such as tobacco leaf flow rate and moisture content. As the tobacco leaves move with the conveyor belt, the atomized droplets are evenly sprayed onto the surface of the tobacco leaves with the help of airflow. Combined with the tumbling of the rollers or stirring mechanism, full contact between the molten material and the tobacco leaves is achieved, ensuring uniform feeding.

[0004] In existing technologies, some tobacco processing feeding devices experience unstable feeding during operation. This instability leads to an imbalance in the contact ratio between the liquid and the tobacco leaves. Some tobacco leaves may have insufficient liquid due to a sudden increase in material quantity, or excessive liquid due to insufficient quantity, resulting in inconsistent finished product quality. To address these issues, a tobacco processing uniform feeding device is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a uniform feeding device for tobacco processing, aiming to improve the problem that some existing tobacco processing feeding devices experience unstable feeding during operation. Unstable feeding can lead to an imbalance in the contact ratio between the liquid and the tobacco leaves, resulting in insufficient liquid for some tobacco leaves due to a sudden increase in material quantity, or excessive liquid due to insufficient quantity, causing inconsistent finished product quality.

[0017] Beneficial effects

[0018] This invention achieves precise and controllable material feeding by setting up an intermittent feeding mechanism driven by a drive mechanism, effectively avoiding the material accumulation or material interruption problems that are easily caused by traditional continuous feeding, and ensuring the uniformity and stability of feeding from the source. The spray head with a swing mechanism is set in the mixing cylinder, which allows the spray head to swing at multiple angles under the drive of the swing mechanism, greatly expanding the spray coverage of the liquid and ensuring that the liquid can be fully mixed with the tobacco shreds in an all-round and three-dimensional manner, thereby significantly improving the uniformity of flavoring and the overall quality of the tobacco shreds.

[0019] In this invention, after the first motor starts, it drives the disc to rotate. The sliding of the sliding column within the arc-shaped guide groove causes the arc-shaped rod to swing, which in turn pushes the connecting plate back and forth via the connecting rod. The sliding plate slides back and forth accordingly; when it moves forward, the flavoring flows from the opening into the conveying pipe, and when it moves backward, the solid part blocks the flow. This structure precisely controls the flavoring flow rate, ensuring that each batch of tobacco and the liquid are mixed evenly in the correct proportion, avoiding imbalances in the feeding process.

[0020] In this invention, the second motor drives the rotating part to rotate, causing the slider to slide within the swing block, which in turn causes the swing rod fixed to the support shell to swing, thereby controlling the spray head to flexibly adjust the spray angle and range. The entire assembly can automatically optimize the coverage effect of the liquid spray according to the distribution of tobacco shreds and process requirements.

[0021] The entire device of this utility model has a reasonable structural layout, integrating storage, conveying and spraying functions into one unit. It has a high degree of automation, which not only effectively reduces the intensity of manual operation and production costs, but also helps to ensure the stability and consistency of product quality during mass production. It has high practical value and promotion prospects. Attached Figure Description

[0034] Example 2

[0035] like Figures 1 to 3 As shown, this utility model embodiment provides a tobacco shredding uniform feeding device, including a base plate 1. The base plate 1 is the basic support structure of the equipment, providing a stable mounting surface for subsequent components, ensuring that the device will not easily shake or shift due to external forces during operation, and ensuring that each component can function normally. A bracket 2 is fixedly connected to one side of the top of the base plate 1, and a storage tank 3 is fixedly connected to the right side of the bracket 2. The bracket 2 not only supports the storage tank 3, keeping it at a suitable height and position, but also provides a three-dimensional installation structure for the entire device, allowing the components to be distributed in an orderly manner and making reasonable use of space. The storage tank 3 is used to store the material to be added, ensuring the continuity of material supply during production, and is the core space for material temporary storage. A mixing cylinder 15 is installed on the other side of the top of the base plate 1 through a rotating device. The mixing cylinder 15 is used to receive the material and tobacco shredding in the storage tank. The rotating device allows the mixing cylinder 15 to rotate around its axis for easy mixing. The material inside the mixing drum 15 is connected to the conveying pipe 14 through the outlet end of the storage drum 3 via an intermittent feeding mechanism. The intermittent feeding mechanism is connected to a driving mechanism. Under the action of the driving mechanism, the intermittent feeding mechanism reciprocates to cut off or release the material. A support rod 16 is fixed inside the mixing drum 15 along the length direction. The conveying pipe 14 passes through the support rod 16 and its multiple output ends are connected to each spray head 23 placed outside the support rod 16 through a connecting pipe 24. Each spray head 23 is connected to a corresponding swing mechanism fixed outside the support rod 16. The swing mechanism is used to drive the spray head 23 to swing inside the mixing drum 15 to achieve uniform spraying of the material.

[0036] In this embodiment, as Figure 2 and Figure 3As shown, a mounting shell 4 is fixedly installed below the mixing cylinder 15. The intermittent feeding mechanism includes a fixed block 13, a sliding plate 12, and a transmission component. The fixed block 13 is located on the top of the mounting shell 4 and has a sliding groove extending along the length direction on one side. The sliding plate 12 is provided inside the sliding groove. One side of the sliding plate 12 is connected to the transmission component through a hinged connecting rod 10. The transmission component is connected to the drive mechanism. The upper and lower sides of the sliding groove are respectively connected to the outlet end of the storage tank 3 and the conveying pipe 14. The conveying pipe 14 passes through the bottom of the mounting shell 4 and enters the interior of the support rod 16.

[0037] In this embodiment, a support plate 5 is fixedly provided at the bottom of the mounting shell 4 on the side near the opening of the sliding groove. The driving mechanism includes a first motor 6 and a disc 7. The first motor 6 is fixed on the support plate 5 on the side away from the opening of the sliding groove, and the driving end of the first motor 6 is connected to the disc 7 near the opening of the sliding groove.

[0038] In this embodiment, the transmission component includes a sliding column 8 eccentrically connected to the disc 7 and an arc-shaped rod 9 with an arc-shaped guide groove. The sliding column 8 is disposed in the arc-shaped guide groove. The lower side of the arc-shaped rod 9 is rotatably connected to the support plate 5. A connecting plate 11 is provided on one side of the sliding plate 12. The connecting plate 11 includes a horizontal plate and a vertical plate. The horizontal plate is fixedly connected to the sliding plate 12. The vertical plate is disposed below the horizontal plate and hinged to one end of the connecting rod 10. The other end of the connecting rod 10 is hinged to the upper side of the arc-shaped rod 9.

[0039] Specifically, a mounting shell 4 is fixedly connected to the bottom of the storage hopper 3. The mounting shell 4 encloses and protects the internal moving parts, preventing external debris from entering and interfering with material conveying. The mounting shell 4 also provides a stable support for the conveying pipe 14, ensuring that the conveying pipe 14 does not loosen during material conveying. A fixing block 13 is provided on the top of the mounting shell 4. A sliding groove is opened inside the fixing block 13, and a sliding plate 12 is provided in the sliding groove. A connecting plate 11 is connected to one side of the sliding plate 12. One end of the connecting rod 10 is hinged to the connecting plate 11, and the other end of the connecting rod 10 is hinged to a drive mechanism connected to the transmission component. A support plate 5 is fixedly connected to the bottom inner side of the mounting shell 4. The drive mechanism includes a first motor 6 and a disc 7. The support plate 5 provides a stable mounting surface for the first motor 6, ensuring the stability of the motor during operation. The first motor 6 is fixedly connected to one side of the support plate 5, and the disc 7 is fixedly connected to the drive end of the first motor 6. After the first motor 6 is energized, it converts electrical energy into mechanical energy and outputs rotational power. Its speed is adjustable, thereby controlling the movement frequency of subsequent components and the rhythm of material conveying. The transmission components include a sliding column 8 and an arc-shaped rod 9. The sliding column 8 is fixedly connected to the disk 7 away from the center. The top of the arc-shaped rod 9 is rotatably connected to a connecting rod 10. The lower end of the arc-shaped rod 9 is rotatably connected to the support plate 5. The arc-shaped rod 9 has an arc-shaped guide groove. The outer side of the sliding column 8 is slidably connected to the inside of the arc-shaped guide groove. The arc-shaped guide groove can provide guidance for the movement of the sliding column 8. When the sliding column 8 moves in a circular motion with the disk 7, it will slide in the arc-shaped guide groove. The sliding column 8 transmits the circular motion of the disk 7 and pushes the arc-shaped rod 9 to swing back and forth around the connection point of the support plate 5, converting the circular motion into arc-shaped swing. The connecting rod 10 converts the swing of the arc-shaped rod 9 into the linear reciprocating motion of the connecting plate 11, realizing the effective transmission of motion.

[0040] In this embodiment, as Figure 4 and Figure 5 As shown, the feed pipe 14 has two output ends, and the support rod 16 has support shells 17 on both sides of its center. The support shell 17 has an mounting plate at its upper end. The swing mechanism includes a second motor 18, a rotating part 19, a swing block 21, and a swing rod 22. The second motor 18 is fixed above the mounting plate, and its drive end is connected to the rotating part 19 located below the mounting plate. The rotating part 19 has a slider 20 below it. The swing block 21 has a groove facing the plane with the largest area of ​​the support shell 17. The slider 20 is slidably connected in the groove. The swing rod 22 extends from the opening at the bottom of the support shell 17 and is connected below the swing block 21. A spray head 23 is fixed below the swing rod 22.

[0041] In this embodiment, the rotating part 19 includes a bending plate and a circular fixed end. The bending plate includes a parallel plate and an inclined plate integrally connected. The parallel plate is parallel to the bottom of the support shell 17 and connected to the drive end of the second motor 18. The angle between the parallel plate and the inclined plate is an obtuse angle and the opening direction is downward. The bottom of the inclined plate is fixedly provided with a circular fixed end for mounting the slider 20.

[0042] Specifically, two support shells 17 are fixedly connected to the bottom end of the support rod 16. The support shells 17 are used to install components such as the second motor 18 and the rotating part 19, providing stable support points for these components and ensuring that they do not shift or shake during operation. They serve as the support structure for the power transmission and mechanical motion of the swing mechanism. The second motor 18 is fixedly connected to the interior of each support shell 17 via mounting plates placed on its upper end. The second motor 18 is one of the power sources of the swing mechanism; after being energized, it converts electrical energy into mechanical energy, outputting rotational power through the drive end to drive the rotating part 19 to rotate. Its speed is adjustable, thereby controlling the movement frequency and amplitude of subsequent components, achieving precise control of the material addition process. The rotating part 19 is fixedly connected to the drive end of the second motor 18, and the rotating part 19 transmits the rotational motion of the second motor 18. The upper end of the rotating part 19 is rotatably connected to the output end of the second motor 18. A slider 20 is fixedly connected to the lower end of the rotating part 19. A swing block 21 is slidably connected to the outer side of the slider 20. A swing rod 22 is fixedly connected to the bottom end of the swing block 21. The swing block 21 swings under the action of the slider 20, driving the swing rod 22 to move, thereby controlling the swing of the spray head 23 and adjusting the spray range and angle of the material. The bottom end of the swing rod 22 is fixedly connected to the spray head 23. The swing rod 22 transmits the swing of the swing block 21 to the spray head 23, enabling the spray head 23 to swing along a predetermined trajectory. The spray head 23 is the material addition actuator; by swinging, it expands the spray range, allowing the material to be sprayed evenly onto the tobacco processing surface. A connecting pipe 24 is fixedly connected to the outer side of the spray head 23, connecting the spray head 23 and the conveying pipe 14, serving as the channel for material to flow from the conveying pipe 14 to the spray head 23. After the second motor 18 starts, it rotates at high speed, driving the rotating part 19 to rotate. When the rotating part 19 rotates, the slider 20 set below it reciprocates within the swing block 21, converting the rotational motion of the rotating part 19 into the reciprocating motion of the slider 20. The reciprocating motion of the slider 20 pushes the swing block 21 to swing, and the swing block 21 then drives the spray head 23 to swing through the swing rod 22, thereby achieving uniform spraying of materials.

[0043] In this embodiment, the mixing drum 15 is provided with fixed seats on both sides and mounted on the base plate 1. The rotating device includes a third motor and an annular guide rail. The third motor is fixed on the base plate 1 by a mounting bracket. The driving end of the third motor is connected to a rotating shaft fixed on the mixing drum 15 on the side away from the support 2. The annular guide rail is sleeved on both sides of the mixing drum 15. A collar is slidably fitted on the outer side of the annular guide rail. Grooves that fit into the collar are provided on both fixed seats.

[0044] In this embodiment, the support 2 includes two vertical rods and a horizontal rod between the two vertical rods. One of the vertical rods is fixedly installed with the storage tank 3 by a clamp. The mixing cylinder 15 is provided with a feeding end and a discharging end. A funnel-shaped feeding port corresponding to the feeding end of the mixing cylinder 15 is installed above the two vertical rods.

[0045] In this embodiment, multiple sets of scrapers are also included. The multiple sets of scrapers are fixedly installed in the chamber of the mixing cylinder 15 and are evenly distributed around the circumference of the chamber of the mixing cylinder 15.

[0046] In this embodiment, a stirring mechanism is also provided in the chamber of the mixing cylinder 15.

[0047] Working principle: The first motor 6 is started, and the first motor 6 starts to run and drive the disc 7 to rotate. The movement of the disc 7 drives the sliding column 8 to rotate. The sliding column 8 slides in the arc-shaped guide groove of the arc-shaped rod 9, so that the arc-shaped rod 9 swings about the connection point with the support plate 5. The swing of the arc-shaped rod 9 drives the connecting plate 11 to move back and forth through the connecting rod 10, thereby driving the sliding plate 12 to slide inside the fixed block 13. When the sliding plate 12 slides forward, the spices in the storage tank 3 will flow from the opening inside the sliding plate 12 to the conveying pipe 14. When the sliding plate 12 moves backward, the solid part of the sliding plate 12 will block the spices in the storage tank 3, stopping the conveying of spices into the equipment. This realizes the control of the feeding of the equipment, avoids the problem of imbalance in the feeding ratio caused by too much or too little feeding, and effectively ensures that each batch of tobacco shreds and liquid can be fully and evenly mixed according to the preset ratio.

[0048] The second motor 18 is started, which drives the rotating part 19 to rotate. The rotation of the rotating part 19 causes the slider 20 to slide inside the swing block 21. The swing rod 22, which is fixedly connected to the other side of the swing block 21, is rotatably connected to the inside of the support shell 17. This allows the slider 20 to swing through the swing block 21 and drive the swing rod 22 to swing, thereby driving the spray head 23 to swing. This allows the equipment to flexibly adjust the direction and coverage of the liquid spraying according to the movement state, accumulation thickness and process requirements of the tobacco shreds in the equipment.

[0049] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
