Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tobacco processing equipment, and particularly relates to a stem filament dehumidification bin. BACKGROUND

[0002] Tobacco stem filament is one of the important raw materials in the tobacco processing process, and its quality directly affects the taste and combustion performance of tobacco products. In the tobacco processing process, stem filament needs to be dehumidified to reduce the moisture content and improve its stability and usability. Dehumidification is usually carried out in a dehumidification bin, which is equipped with a dehumidification device and a stirring mechanism. The dehumidification device reduces the humidity in the bin to dry the stem filament, and the stirring mechanism is used to stir the accumulated stem filament to make it evenly contact with the air, thereby achieving uniform dehumidification.

[0003] However, the existing dehumidification bin stirring mechanism has certain limitations. The traditional stirring mechanism usually uses a stirring plate with a fixed length, which is difficult to achieve uniform stirring when facing different volumes and types of stem filament. Because the bulk density and volume of stem filament may vary due to differences in type and processing technology, the fixed length of the stirring plate cannot be adjusted flexibly, resulting in some stem filament not being able to fully contact the air, thereby affecting the dehumidification effect. In addition, the traditional stirring mechanism also has poor adaptability when dealing with different dehumidification bin capacities, making it difficult to meet diverse production needs.

[0004] In order to solve the above problems, some improvement schemes are proposed in the prior art, such as adjusting the stirring plate speed or increasing the number of stirring plates to improve the stirring effect. However, these schemes still cannot fundamentally solve the limitations caused by the fixed length of the stirring plate, especially when dealing with different volumes and types of stem filament, there is still a problem of uneven stirring. Therefore, there is an urgent need for a dehumidification bin stirring mechanism that can flexibly adjust the length of the stirring plate according to the volume and type of stem filament to improve the uniformity and efficiency of stem filament dehumidification.

[0005] Based on the above background, the present application proposes a new type of stem filament dehumidification bin, which can flexibly adjust the length of the stirring plate according to the volume and type of stem filament by designing a telescopic stirring plate structure, thereby achieving uniform stirring and efficient dehumidification of different stem filaments. This design not only improves the adaptability of the dehumidification bin, but also significantly improves the quality and efficiency of stem filament dehumidification. CONTENT OF THE INVENTION

[0009] The cut stem dehumidifying bin further comprises the following additional technical features.

[0010] The first plate body and the second plate body are hollow, the first plate body is sleeved on the outside of the second plate body, the push-pull piece comprises a push-pull rod and a driving piece in the rotating shaft, the push-pull rod is arranged in the first plate body and the second plate body and connected with the driving piece and the inner wall of the second plate body respectively, and the driving piece drives the push-pull rod to stretch or shrink to drive the second plate body to move.

[0012] The second plate body has a first limit position close to the rotating shaft and a second limit position away from the rotating shaft, the guide sliding groove has a first stop part and a second stop part, when the second plate body is located at the first limit position, the guide convex part abuts against the first stop part, and when the second plate body is located at the second limit position, the guide convex part abuts against the second stop part.

[0013] The number of the first guide sliding groove and the first guide convex part is multiple, and they are arranged at intervals on the outer surfaces of the first plate body and the second plate body.

[0014] The number of the dehumidifying cavities is multiple, and the multiple dehumidifying cavities are arranged at intervals along the height direction of the bin body, and two adjacent dehumidifying cavities are separated by a separation plate.

[0015] The separation plate is provided with a through hole for the rotating shaft, the through holes are vertically projected and overlapped, and the rotating shaft penetrates the multiple through holes to pass through the dehumidifying cavities, and multiple stirring plates are arranged in each dehumidifying cavity along the extension direction of the rotating shaft.

[0016] The dehumidifying device comprises a fan and an air duct connected with the fan, the air duct is at least partially located in the dehumidifying cavity, the air duct has an air outlet located in the dehumidifying cavity, the dehumidifying cavity is provided with an air outlet communicating with the outside, and the fan transports air into the dehumidifying cavity through the air duct.

[0018] The bin body is provided with an inlet and an outlet, the inlet is located at the top of the bin body, the outlet is located below the bin body, and the bin body further comprises a first closure movably arranged at the inlet and a second closure movably arranged at the outlet.

[0019] Thanks to the above technical solutions, the application has the following advantages:

[0020] 1. The cut stem dehumidifying bin comprises a dehumidifying cavity for placing cut stems, and a dehumidifying device is arranged in the dehumidifying cavity to reduce the moisture content in the dehumidifying cavity, thereby achieving the effect of dehumidifying the cut stems in the dehumidifying cavity. The dehumidifying bin further comprises a stirring mechanism arranged in the dehumidifying cavity, which rotates the stirring plate through a rotating shaft to stir the cut stems, so that the cut stems can be fully and uniformly contacted with air to achieve uniform dehumidification of the cut stems. On this basis, the adjustable length of the stirring plate design solves the problem that the traditional fixed length stirring plate cannot adapt to different volumes and different types of cut stems, and improves the stirring uniformity. For example, when the cut stems placed in the dehumidifying cavity have a large volume, the second plate body can be pushed by the push-pull piece to extend the length of the stirring plate, so that it can cover more volume of cut stems to achieve full coverage of the cut stems, reduce the probability that the stirring plate cannot uniformly stir the cut stems due to the limited length of the stirring plate, and ensure the uniformity of cut stem dehumidification, which helps to improve the dehumidification effect of the cut stems. When the cut stems placed in the dehumidifying cavity have a small volume, the second plate body can be pulled by the push-pull piece to move in the second direction, thereby shortening the length of the stirring plate, so that the stirring plate can cover all the cut stems. In this way, the distance between the center of gravity of the stirring plate and the rotating shaft is shortened, and the rotating shaft only needs a small driving force to drive the stirring plate to rotate to stir the cut stems.

[0042] As shown in Figures 1 to 4 A cut stem dehumidification bin for dehumidifying tobacco cut stems includes a bin body 1, which has a dehumidification cavity 11 inside. A dehumidification device and a raking mechanism are arranged in the dehumidification cavity 11. The raking mechanism includes a rotating shaft 2 and a raking plate 3 arranged on the rotating shaft 2. The rotating shaft 2 rotates to drive the raking plate 3 to rotate and rake in the dehumidification cavity 11. The raking plate 3 includes a first plate body 31 connected with the rotating shaft 2 and a second plate body 32 connected with the first plate body 31. The raking mechanism further includes a push-pull piece 4 acting on the second plate body 32. The push-pull piece 4 can drive the second plate body 32 to move in a first movement direction away from the first plate body 31 and in a second movement direction close to the first plate body 31, so as to lengthen or shorten the raking plate 3.

[0043] The cut tobacco dehumidification bin of the present application comprises a dehumidification cavity 11 for placing cut tobacco, wherein a dehumidification device is arranged to reduce the moisture content in the dehumidification cavity 11, thereby achieving the effect of dehumidifying the cut tobacco in the dehumidification cavity 11. The dehumidification bin of the present application further comprises a stirring mechanism arranged in the dehumidification cavity 11, which is driven by the rotating shaft 2 to rotate the stirring plate 3, thereby stirring the cut tobacco and enabling the cut tobacco to fully and uniformly contact with air to achieve uniform dehumidification of the cut tobacco. On this basis, the adjustable length of the stirring plate 3 solves the problem of the traditional fixed length stirring plate 3 being difficult to adapt to different volumes and different types of cut tobacco, thereby improving the uniformity of stirring. For example, when the cut tobacco placed in the dehumidification cavity 11 has a large volume, the second plate body 32 can be pushed by the push-pull piece 4 to extend the length of the stirring plate 3, so that it can cover more volume of cut tobacco, thereby achieving full coverage of the cut tobacco and reducing the probability that the stirring plate 3 cannot uniformly stir the cut tobacco due to the limited length of the stirring plate 3, thereby ensuring the uniformity of cut tobacco dehumidification and helping to improve the dehumidification effect of the cut tobacco. When the cut tobacco placed in the dehumidification cavity 11 has a small volume, the second plate body 32 can be pulled by the push-pull piece 4 to move in the second direction, thereby shortening the length of the stirring plate 3, so that the stirring plate 3 can cover all the cut tobacco. In this way, the distance between the center of gravity of the stirring plate 3 and the rotating shaft 2 is shortened, and the rotating shaft 2 only needs a small driving force to drive the stirring plate 3 to rotate to stir the cut tobacco.

[0044] As a preferred embodiment of the present application, as shown in Figures 2 to 4 the first plate body 31 and the second plate body 32 are hollow inside, the first plate body 31 is sleeved outside the second plate body 32, the push-pull piece 4 comprises a push-pull rod 41 and a driving piece 42 located inside the rotating shaft 2, the push-pull rod 41 is located inside the first plate body 31 and the second plate body 32 and connected with the driving piece 42 and the inner wall of the second plate body 32 respectively, and the driving piece 42 drives the push-pull rod 41 to extend or retract to drive the second plate body 32 to move. By designing the hollow and sleevable first plate body 31 and the second plate body 32, and the push-pull piece 4 composed of the driving piece 42 and the push-pull rod 41, the length of the stirring plate 3 can be flexibly adjusted. The hollow first plate body 31 and the second plate body 32 provide a space for the push-pull rod 41, which saves the space occupied by the push-pull rod 41 outside the stirring plate 3, and helps to optimize the structural design of the stirring mechanism.

[0045] The push-pull rod 41 can be in the form of a hydraulic rod, an electric push rod or a pneumatic push rod, and the driving piece 42 can be in the form of a motor, a hydraulic pump or a gas pump. By using these different forms of push-pull pieces 4, the second plate body 32 can be accurately controlled, thereby further improving the uniformity and efficiency of stirring.

[0046] As a preferred embodiment of the present embodiment, as shown in Figures 2 to 4As shown, one of the first plate body 31 and the second plate body 32 is provided with the guide sliding groove 5, and the other is provided with the guide protrusion 6 which is adapted to the guide sliding groove 5 and is located in the guide sliding groove 5 to guide the movement of the second plate body 32.

[0047] The design of the guide sliding groove 5 and the guide protrusion 6 enables the second plate body 32 to smoothly slide in the first plate body 31, so as to adjust the length of the poking plate 3 according to different cut tobacco volumes and types, and ensure uniform poking and efficient dehumidification of the cut tobacco. The design of the guide sliding groove 5 and the guide protrusion 6 can have various implementations. For example, the guide sliding groove 5 can be arranged on the inner wall of the first plate body 31, and the guide protrusion 6 is arranged on the outer wall of the second plate body 32; conversely, the guide sliding groove 5 can be arranged on the inner wall of the second plate body 32, and the guide protrusion 6 is arranged on the outer wall of the first plate body 31. Further, the number of the guide sliding groove 5 and the guide protrusion 6 can be adjusted according to actual needs, which can be single or multiple, so as to ensure the smooth and reliable movement of the second plate body 32.

[0048] As a preferred example under the present embodiment, as shown in Figure 3 The second plate body 32 has a first limit position close to the rotating shaft 2 and a second limit position away from the rotating shaft 2, and the guide sliding groove 5 has a first stop portion and a second stop portion 52. When the second plate body 32 is located at the first limit position, the guide protrusion 6 abuts against the first stop portion, and when the second plate body 32 is located at the second limit position, the guide protrusion 6 abuts against the second stop portion 52.

[0049] The first stop portion and the second stop portion 52 of the guide sliding groove 5 correspond to the first limit position and the second limit position of the second plate body 32 respectively, and through the action of the first stop portion and the second stop portion 52, the movement range of the second plate body 32 can be effectively limited to avoid exceeding the predetermined position. In addition, the cooperation of the guide sliding groove 5 and the guide protrusion 6 can further improve the durability and reliability of the poking mechanism. Specifically, the first stop portion and the second stop portion 52 are the inner walls of the guide sliding groove 5 close to the rotating shaft 2 and away from the rotating shaft 2 respectively, and the guide protrusion 6 slides in the guide sliding groove 5. When the guide protrusion 6 slides to abut against the first stop portion, it cannot continue to move towards the rotating shaft 2, thereby limiting the movement of the second plate body 32 towards the rotating shaft 2; similarly, when the guide protrusion 6 slides to abut against the second stop portion 52, it cannot continue to move away from the rotating shaft 2, thereby limiting the movement of the second plate body 32 away from the rotating shaft 2.

[0050] Preferably, the number of the first guide sliding groove 5 and the first guide protrusion 6 is multiple, and they are arranged on the outer surfaces of the first plate body 31 and the second plate body 32 respectively.

[0051] The first guide sliding groove 5 and the first guide protrusion 6 are arranged between the first plate body 31 and the outer surface of the second plate body 32, so that the second plate body 32 can be better guided and supported during movement, thereby ensuring the stability and smoothness of the movement. This design not only improves the accuracy and reliability of the extension and retraction movement of the poking plate 3, but also effectively avoids the situation of jamming or deviation during the poking process.

[0052] As a preferred embodiment of the present application, as shown in Figure 1 The number of dehumidification cavities 11 is multiple, and the multiple dehumidification cavities 11 are arranged along the height direction of the bin body 1, and the adjacent two dehumidification cavities 11 are separated by a partition plate 7.

[0053] The dehumidification cavities 11 are designed to be multiple, and the dehumidification cavities 11 are arranged along the height direction of the bin body 1. Through this design, multi-level dehumidification treatment can be carried out in the same bin body 1, improving the space utilization and processing efficiency. Each dehumidification cavity 11 is separated by a partition plate 7, so that the cut tobacco in different dehumidification cavities 11 can be prevented from mixing, and the dehumidification treatment in each dehumidification cavity 11 can be carried out independently.

[0054] The increase in the number of dehumidification cavities 11 allows the dehumidification bin to process more cut tobacco at the same time, improving the overall processing efficiency.

[0055] As a preferred embodiment of the present embodiment, the partition plate 7 is provided with a through hole for the rotating shaft 2 to pass through, the through holes are vertically projected and coincided, the rotating shaft 2 passes through the multiple through holes in sequence to penetrate each dehumidification cavity 11, and multiple poking plates 3 are arranged in each dehumidification cavity 11 along the extension direction of the rotating shaft 2.

[0056] The partition plate 7 not only effectively separates different dehumidification cavities 11, but also has a through hole for the rotating shaft 2 to pass through. The synchronous operation of the poking mechanism in multiple dehumidification cavities 11 is realized by the penetration of the rotating shaft 2. Specifically, the rotating shaft 2 passes through the multiple through holes in sequence to penetrate each dehumidification cavity 11, and multiple poking plates 3 are arranged in each dehumidification cavity 11 along the extension direction of the rotating shaft 2. Through this design, uniform poking and efficient dehumidification of the cut tobacco in multiple dehumidification cavities 11 can be realized.

[0057] The through hole on the partition plate 7 can adopt various forms, such as a circular hole or an elliptical hole, to adapt to different design requirements. The rotating shaft 2 can be fixed in the through hole by a bearing or other support structure to ensure its stability during rotation. The number and arrangement of the poking plates 3 can be adjusted according to specific dehumidification requirements to achieve the best poking effect.

[0058] As a preferred embodiment of the present application, as shown in Figure 1As shown, the dehumidifying device includes a fan 9 and an air duct 8 connected to the fan 9, the air duct 8 is at least partially located in the dehumidifying cavity 11, the air duct 8 has an air outlet 81 located in the dehumidifying cavity 11, the dehumidifying cavity 11 is provided with an air outlet 111 communicating with the outside, and the fan 9 sends air into the dehumidifying cavity 11 through the air duct 8.

[0059] The present application solves the problem of low efficiency in the dehumidifying process of the traditional cut stem dehumidifying bin by adding a dehumidifying device. The fan 9 of the dehumidifying device sends air into the dehumidifying cavity 11 through the air duct 8, and the air is evenly distributed in the dehumidifying cavity 11 by the air outlet 81, thereby accelerating the dehumidifying process of the cut stem. The humid air in the dehumidifying cavity 11 is discharged through the air outlet 111, maintaining a dry environment in the dehumidifying cavity 11.

[0060] The air duct 8 of the dehumidifying device is designed to be at least partially located in the dehumidifying cavity 11, which can ensure the optimization of the air flow path, so that the air in the dehumidifying cavity 11 can evenly contact the cut stem, improving the dehumidifying efficiency. The position and number of the air outlet 81 can be adjusted according to the size and shape of the dehumidifying cavity 11 to ensure that the air can be evenly distributed in the entire dehumidifying cavity 11.

[0061] Further, the air outlet 111 is provided with a controllable valve, which can adjust the air flow according to the needs, thereby realizing accurate control of the humidity in the dehumidifying cavity 11.

[0062] By introducing the dehumidifying device, the dehumidifying efficiency and uniformity of the cut stem dehumidifying bin are significantly improved. Compared with the traditional dehumidifying bin, the design of the present application not only can adapt to different volumes and types of cut stems, but also can realize efficient dehumidifying in a short time. Therefore, the quality and stability of the cut stem are significantly improved, meeting the diversified production needs.

[0063] As a preferred embodiment of the present application, as shown in the drawings, Figure 1 As shown, the bin body 1 is provided with an inlet 12 and an outlet 13, the inlet 12 is located at the top of the bin body 1, the outlet 13 is located below the bin body 1, and further comprises a first closure movably arranged at the inlet 12 and a second closure movably arranged at the outlet 13.

[0064] The technical scheme of the design includes arranging the inlet 12 at the top of the bin body 1 to facilitate the feeding of cut stems into the dehumidifying bin, and arranging the outlet 13 below the bin body 1 to facilitate the discharge of cut stems from the bin body 1 after dehumidifying. The inlet 12 and the outlet 13 are respectively provided with a first closure and a second closure, which can be movably arranged to open or close the inlet 12 and the outlet 13 when needed, thereby controlling the entry and exit of cut stems.

[0065] The technical features of the design are that by setting the feeding port 12 and the discharging port 13 at the top and bottom of the dehumidification bin respectively, and matching with movable closures, the convenient feeding and discharging of cut stem can be realized. At the same time, the setting of the closure ensures the sealing during the dehumidification process, preventing external air from affecting the dehumidification effect. Specifically, the first closure and the second closure can be controlled by mechanical or electric means to realize automatic operation and improve production efficiency. For example, the first closure and the second closure can adopt pneumatic valves or electric valves, which are uniformly managed by the control system.

[0066] The design solves the problem of the convenience of feeding and discharging cut stem in the dehumidification bin by setting the feeding port 12 and the discharging port 13 and matching with movable closures. Compared with the prior art, the design not only improves the convenience of operation, but also ensures the sealing during the dehumidification process, thereby improving the quality and efficiency of cut stem dehumidification.

[0068] Each embodiment in the specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other. Each embodiment focuses on the difference from other embodiments.

[0069] The above is only an embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
