Description

Technical Field

[0001] This utility model relates to the field of tobacco manufacturing technology, and in particular to a tobacco drying device. Background Technology

[0002] Tobacco shreds refer to tobacco produced by cutting tobacco leaves into shreds, adding auxiliary materials, and then fermenting and storing them. When tobacco leaves are processed into tobacco shreds, the moisture inside them can prevent them from being lit when the finished product is made. Therefore, it is necessary to use a drying device to dry the moisture inside the tobacco shreds in advance.

[0003] In existing tobacco drying devices, after drying, workers need to open the seal, remove the receiving cylinder, and then collect the tobacco. This manual collection method, while saving some collection time compared to traditional methods, can also cause worker fatigue, leading to reduced work efficiency. Furthermore, the receiving cylinder containing tobacco is very heavy, often requiring at least two people to operate simultaneously, increasing labor costs and raising safety hazards in the working environment.

[0004] Therefore, there is an urgent need for a tobacco drying device to solve the above problems. Utility Model Content

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] like Figures 1 to 5 As shown, this utility model discloses a tobacco drying device, including a base 1 and a feeding module 5. A heating barrel 2 is placed on the base 1, and the heating barrel 2 has a heating chamber inside. The heating barrel 2 is used to provide heat to heat the heating chamber. A feeding hopper 412 is rotatably arranged inside the heating chamber. The feeding hopper 412 is used to place the tobacco to be dried and to continuously turn the tobacco, so that the heating and drying effect is more uniform. A detachable barrel cover 201 is provided at one end of the heating barrel 2. The barrel cover 201 can block the inlet and outlet of the heating barrel 2 and the feeding hopper 412, respectively playing the roles of heat preservation and sealing. The feeding module 5 includes a pusher assembly and a feeding disc 504 mounted on the base 1 and the heating barrel 2. The feeding disc 504 is embedded in and blocks the material barrel 412. One end of the pusher assembly passes through the end of the heating barrel 2 away from the barrel cover 201 and is fixedly connected to the feeding disc 504, so that the feeding disc 504 can slide back and forth in the material barrel 412 along the feeding direction to push out the dried tobacco shreds. This facilitates the collection of the dried tobacco shreds by the staff, ensuring safe operation, saving manpower, and improving the overall drying efficiency. For example, the base 1 has a receiving slope 101 at the bottom near the barrel cover 201, which can further improve the receiving efficiency and prevent the tobacco shreds from scattering when pushed out.

[0035] Specifically, a vent cylinder 3 is fixedly installed on the heating tank 2. The vent cylinder 3 connects the heating chamber to the outside and is used to balance the air pressure inside the heating tank 2 and discharge water vapor. A conical air guide 301 is supported on the top of the vent cylinder 3. The air guide 301 can change the direction of air discharge to prevent high-temperature water vapor from being directly sprayed out and causing safety hazards. In addition, the air guide 301 can collect and guide the condensate formed by the water vapor to the surrounding area to prevent the condensate from flowing back and clogging the vent cylinder 3.

[0036] In this embodiment, the push rod assembly includes an electric threaded rod 501 and a push rod 502. A support platform 102 is provided on the base 1, and the drive end of the electric threaded rod 501 is placed on the support platform 102. The working end of the electric threaded rod 501 is threadedly connected to the push rod 502. The support platform 102 has a certain height to support the electric threaded rod 501, so that the extension direction of both the working end of the electric threaded rod 501 and the extension direction of the push rod 502 are parallel to the pushing direction. The push rod 502 is fixedly welded to the pusher plate 504. The working end of the electric threaded rod 501 can rotate to move the push rod 502 along the pushing direction. By controlling the forward or reverse rotation of the working end of the electric threaded rod 501, the forward or reverse movement of the push rod along the pushing direction can be changed. For example, the connection point between the push rod 502 and the pusher plate 504 is located at the center of the pusher plate 504, making the sliding of the pusher plate 504 more stable.

[0037] Furthermore, a limiting block 503 is welded to the push rod 502, and a limiting hole is provided on the heating barrel 2. The push rod 502 slides through the limiting hole and passes through the heating barrel 2, thereby pushing the pusher plate 504 inside the material barrel 412. At the same time, the limiting block 503 and the limiting hole are slidably engaged to prevent the working end of the electric threaded rod 501 from rotating and causing the push rod 502 and the pusher plate 504 to twist.

[0038] Optionally, the feeding module 5 also includes an air blowing assembly, which includes an air pump 505 and an air pipe 506. The feeding plate 504 has an air blowing hole 508. The end of the air blowing hole 508 away from the lid 201 is connected to the air pipe 506. The air pipe 506 is connected to the air pump 505 and can provide jet gas to the air blowing hole 508 so that the air blowing hole 508 blows air into the material barrel 412. This can clean the tobacco and residue on the inner wall of the material barrel 412 at the same time as feeding, thus speeding up the feeding process. For example, the air pipe 506 is made of high-temperature rubber, which can withstand high temperatures. The air pipe 506 is telescopic and can adapt to different positions and distances of the air pump 505 and the feeding module 5.

[0039] Specifically, the pusher plate 504 is provided with an air chamber. On the side of the pusher plate 504 near the barrel cover 201, multiple air blowing holes 508 are arranged in a circular array. All air blowing holes 508 are connected to the air chamber. On the side of the pusher plate 504 away from the barrel cover 201, an air inlet pipe 507 is welded. The air inlet pipe 507 connects the air pipe 506 and the air chamber. When the air pump 505 is working, gas can be sprayed out from multiple air blowing holes 508 at the same time, thereby cleaning the inner wall of the material barrel 412. The multiple air blowing holes 508 distributed in a ring make the air cleaning more uniform.

[0040] In this embodiment, the tobacco drying device further includes a flipping module, which is disposed inside the base 1 and the heating barrel 2. The flipping module includes a drive component 401 and a first gear component 403. The drive component 401 fixed to the base 1 can be a servo motor. A gear part 411 is provided on the outer periphery of the material barrel 412. The first gear component 403 is meshed with the gear part 411. The drive component 401 can provide a rotational force to control the first gear component 403 so that the material barrel 412 meshed with the first gear component 403 can rotate smoothly.

[0041] Furthermore, to stabilize the rotation of the material bucket 412, the tilting module also includes a second gear component 404, which meshes with the gear section 411. The working end of the drive component 401 is welded with a first pulley 402 coaxially arranged with the working end of the drive component 401. A second pulley 405 and a third pulley 406 coaxially arranged with the first gear component 403 are welded to one side of the first gear component 403. A fourth pulley 407 coaxially arranged with the second gear component 404 is welded to one side of the second gear component 404. The first pulley 402 and the second pulley 405 are connected by a first transmission belt 408, and the third pulley 406 and the fourth pulley 407 are connected by a second transmission belt 409. Through a drive component 401 and a belt transmission structure, the first gear component 403 and the second gear component 404 are driven to rotate the material bucket 412 simultaneously, which can ensure that the rotation of the material bucket 412 has sufficient and stable power.

[0042] For example, the flipping module also includes a limiting wheel 410, which is rotatably placed on the base 1. The outer periphery of the material barrel 412 and the gear part 411 are provided with a ring engagement part 413 at intervals. The ring engagement part 413 is embedded in the groove of the limiting wheel 410 and forms a transmission with the limiting wheel 410. This can be used with a large-scale tobacco drying device to further ensure the rotational stability of the material barrel 412 in the length direction, thereby making the tobacco drying more uniform.

[0043] The working principle of this tobacco drying device is as follows: First, the tobacco is placed into the material hopper 412. Then, the drive component 401 drives a series of gears, including the first pulley 402, the second pulley 405, the third pulley 406, and the fourth pulley 407, to rotate the first gear component 403 and the second gear component 404, thereby rotating the material hopper 412 and ensuring uniform drying of the tobacco. After drying, the hopper lid 201 is opened, and the electric threaded rod 501 and the air pump 505 are started. The electric threaded rod 501, in conjunction with the push rod 502, pushes the pusher plate 504 inside the material hopper 412, pushing the tobacco out of the hopper 412 for collection. At the same time, the air provided by the air pump 505 is discharged from the air blowing hole 508, which can speed up the pushing process and also clean the tobacco and residue on the inner wall of the material hopper 412, thus safely and labor-savingly collecting the dried tobacco.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
