Description

Technical Field

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

[0002] Tobacco rehumidification, as one of the core processes in modern high-quality tobacco processing, primarily functions to deeply optimize the physical properties and chemical composition of tobacco leaves through precise and coordinated control of key parameters such as temperature and moisture. This significantly improves the quality, taste, and industrial processing suitability of the tobacco leaves. Therefore, tobacco rehumidification cylinders play an indispensable role in the feeding, rehumidification, and discharging processes.

[0003] During tobacco production, tobacco residue remaining on the inner wall and front and rear ends of the tobacco rehumidification cylinder is an unavoidable problem in domestic cigarette factories. If this residue flows into subsequent production lines, it will contaminate the entire batch of products, leading to serious product quality incidents. During the rehumidification process, tobacco material often accumulates and adheres to the inner wall of the rehumidification cylinder, and the cylinder's built-in cleaning function is insufficient to clean the adhered tobacco leaves thoroughly. Furthermore, if contaminated tobacco leaves flow into subsequent production lines, it will also create a negative experience for consumers, thus affecting the company's image. To avoid such risks, traditional cleaning methods typically require specialized cleaning personnel to enter the rehumidification cylinder to promptly remove the adhered tobacco leaves. However, due to uncontrollable human factors, tobacco contamination by debris is still unavoidable. In addition, the poor working environment inside the cylinder, such as high temperatures, strong tobacco odor, confined space, and protruding stirring rakes, makes manual cleaning inefficient and poses a safety hazard to cleaning personnel. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to overcome the shortcomings of the related technology, and the present invention provides a tobacco rehumidification cylinder cleaning device.

[0005] This invention provides the following technical solution: A tobacco rehumidification drum cleaning device includes a body, a cleaning device, and a moving device.

[0006] The cleaning device is mounted on the machine body and includes a nozzle connected to an external water supply system via a water pipe for rinsing the inner wall of the rehumidification cylinder. The moving device includes a lower support leg and movable support legs. The lower support leg is mounted below the machine body to provide support. Multiple movable support legs are provided, and each movable support leg is connected to the side of the machine body via a telescopic assembly. The movable support leg is connected to the movable end of the telescopic assembly, and the machine body is connected to the fixed end of the telescopic assembly. Support wheels are mounted on the ends of the lower support legs and movable support legs facing away from the machine body, and the axes of each support wheel are perpendicular to the axis of the rehumidification cylinder. The support wheels on the lower support legs are driven by a motor. The telescopic assembly can drive each movable support leg to move away from the machine body, thereby pressing the support wheels on each movable support leg against the inner wall of the rehumidification cylinder.

[0007] As a further improvement to the above technical solution, the telescopic components on each of the movable legs are hinged to the side of the machine body. The machine body is provided with a first swing motor corresponding to the movable leg. The first swing motor is connected to the telescopic components on the movable leg. The first swing motor can drive the movable leg to swing in a plane perpendicular to the axis of the rehumidification cylinder.

[0008] As a further improvement to the above technical solution, a second swing motor is provided on the swing end of the first swing motor. The second swing motor is connected to the telescopic component on the movable support leg. The second swing motor can drive the movable support leg to move towards or away from the axis of the rehumidification cylinder.

[0009] As a further improvement to the above technical solution, the support wheels at the ends of the lower support leg and the movable support leg away from the body are provided in at least two rows, with multiple support wheels in each row, and elastic elements are provided between the connecting seat of each support wheel and the end of the lower support leg or the movable support leg away from the body.

[0010] As a further improvement to the above technical solution, at least two lower support legs are provided parallel to each other on the body along the axial direction of the rehumidification cylinder.

[0011] As a further improvement to the above technical solution, the machine body is provided with two auxiliary support legs, which are symmetrically arranged on both sides of the lower support leg. The plane where the edges of the two lower support legs are located is perpendicular to the axis of the rehumidification cylinder. The end of the auxiliary support leg away from the machine body is provided with a support wheel.

[0012] As a further improvement to the above technical solution, the movable support leg is provided with a clamping device, which includes a claw. The claw is assembled and connected to the movable support leg through the telescopic assembly. The claw is assembled and connected to the movable end of the corresponding telescopic assembly, and the movable support leg is assembled and connected to the fixed section of the corresponding telescopic assembly. The telescopic assembly can drive the claw to move closer to the rake nail on the inner wall of the rehumidification cylinder, and the claw is used to engage and fix with the rake nail. The movable support leg is provided with a third swing motor, which is drivenly connected to the telescopic assembly corresponding to the claw. The third swing motor can drive the claw to swing relative to the movable support leg.

[0013] As a further improvement to the above technical solution, the telescopic assembly includes a fixed outer cylinder, a telescopic inner cylinder, a transmission rod, and a telescopic motor. The fixed end is located on the fixed outer cylinder, and the movable end is located on the telescopic inner cylinder. The telescopic inner cylinder is inserted into the fixed outer cylinder via a guide rail. The transmission rod is rotatably mounted on the fixed outer cylinder and inserted into the telescopic inner cylinder via a threaded connection. The telescopic motor is mounted on the fixed outer cylinder and is connected to the transmission rod for transmission. The telescopic motor drives the transmission rod to rotate relative to the fixed outer cylinder, thereby driving the telescopic inner cylinder to telescopically move relative to the fixed outer cylinder.

[0014] As a further improvement to the above technical solution, the cleaning device further includes a translation seat, a rotating seat, and a pitching seat. The translation seat is horizontally movable relative to the machine body and is mounted on the machine body. A first adjusting motor is mounted on the machine body to drive the translation seat to move along the axis of the rehumidification cylinder. The rotating seat is rotatably mounted on the translation seat and is mounted on the translation seat to drive the rotating seat to rotate radially relative to the rehumidification cylinder. The pitching seat is mounted on the rotating seat via a hinge connection and is mounted on the rotating seat to drive the pitching seat to pitch and swing. The nozzle is mounted on the pitching seat. A camera is mounted on the rotating seat.

[0015] Compared with related technologies, the advantages of this invention are: The tobacco rehumidification cylinder cleaning equipment provided by this invention requires the use of a transport vehicle for transportation and positioning before cleaning the tobacco rehumidification cylinder. The operator places the cleaning equipment stably on the lifting platform of the transport vehicle. Then, by controlling the transport vehicle's control system, the lifting platform is slowly raised, gradually lifting the cleaning equipment to a height corresponding to the rehumidification cylinder inlet. Once the equipment reaches the appropriate height, the transport vehicle is slowly moved to ensure the cleaning equipment is transported to the rehumidification cylinder inlet, thus preparing it for subsequent entry into the rehumidification cylinder.

[0016] Once the cleaning equipment reaches the inlet of the rehumidification drum, it enters the process of moving into the drum. At this point, the power motor mounted on the lower support leg, which provides stable support for the machine, is activated. This motor, acting as the power source for the equipment's movement, transmits power to the support wheels on the lower support leg via a transmission device. Driven by this power, the support wheels begin to rotate smoothly, propelling the entire cleaning equipment slowly into the rehumidification drum.

[0017] As the cleaning equipment gradually penetrates deeper into the rehumidification tank, adjustments to the support structure are necessary to ensure stable operation. Operators use control devices to extend the telescopic components between the outriggers and the main body. Powered by the telescopic components, the components gradually extend according to a preset program and speed, propelling the outriggers outward. The support wheels on the outriggers also move closer to the inner wall of the rehumidification tank. With the continued action of the telescopic components, the support wheels on each outrigger eventually come into close contact with the inner wall of the rehumidification tank. At this point, sufficient friction is generated between the support wheels and the inner wall, creating stable circumferential support for the equipment within the tank. This allows the cleaning equipment to remain securely in its designated position, providing reliable support for subsequent cleaning operations.

[0018] Once the cleaning equipment is stably supported inside the rehumidification cylinder, the cleaning device on the machine can be activated to officially begin the cleaning operation. Driven continuously by the motor, the entire machine moves slowly along the axis of the rehumidification cylinder. The nozzles of the cleaning device are connected to an external water supply system. As the machine moves, the external water supply system delivers pressurized water to the cleaning device. The nozzles of the cleaning device spray the delivered water evenly and powerfully, forming a fine water stream that thoroughly and completely washes the inner wall of the rehumidification cylinder. The water stream effectively washes away tobacco residue, dirt, and other impurities adhering to the inner wall of the rehumidification cylinder, thus achieving the purpose of cleaning the cylinder.

[0019] It is worth mentioning that the entire operation of the aforementioned equipment has significant advantages. Due to the use of this automated cleaning equipment, there is no need for operators to enter the rehumidification cylinder for manual cleaning. The interior space of the rehumidification cylinder is relatively small and may contain adverse environmental factors such as high temperature, humidity, and odors. Manual cleaning is not only labor-intensive but also poses certain safety risks. The cleaning equipment of this invention can be operated entirely from outside the rehumidification cylinder, automatically completing a series of actions such as entry, support, and cleaning. This effectively avoids direct contact between operators and the adverse environment inside the rehumidification cylinder, greatly reducing the dangers during the cleaning process. At the same time, the automated cleaning process is more efficient and precise, significantly shortening cleaning time and improving cleaning efficiency, providing strong support for the production and operation of tobacco production enterprises.

[0029] like Figure 1 As shown, an embodiment of the present invention provides a tobacco rehumidification cylinder cleaning device, including a body 200, a cleaning device 300, and a moving device 400.

[0030] The cleaning device 300 is mounted on the body 200. The cleaning device 300 includes a nozzle 310, which is connected to an external water supply system via a water pipe for rinsing the inner wall of the rehumidification cylinder 100. The motion device 400 includes a lower support leg 410 and movable support legs 420. The lower support leg 410 is mounted below the body 200 to provide support for the body 200. Multiple movable support legs 420 are provided, and each movable support leg 420 is connected to the side of the body 200 via a telescopic assembly 500. The movable support leg 420 is connected to the telescopic assembly 500 via a telescopic mechanism. The moving end is assembled and connected, and the fixed end of the body 200 is assembled and connected to the telescopic assembly 500; the lower support leg 410 and the movable support leg 420 are each equipped with a support wheel 411 at the end away from the body 200, and the axis of each support wheel 411 is perpendicular to the axis of the rehumidification cylinder 100; the support wheel 411 on the lower support leg 410 is driven by a power motor; the telescopic assembly 500 can drive each of the movable support legs 420 to move away from the body 200, so that the support wheel 411 on each of the movable support legs 420 presses against the inner wall of the rehumidification cylinder 100.

[0031] The tobacco rehumidification cylinder cleaning equipment provided in this embodiment requires a transport vehicle for transportation and positioning before cleaning the tobacco rehumidification cylinder 100. The operator places the cleaning equipment stably on the lifting platform of the transport vehicle. Then, by controlling the transport vehicle's control system, the lifting platform is slowly raised, gradually lifting the cleaning equipment to a height corresponding to the inlet of the rehumidification cylinder 100. Once the equipment reaches the appropriate height, the transport vehicle is slowly moved to ensure the cleaning equipment can be transported to the inlet of the rehumidification cylinder 100, thus preparing it for subsequent entry into the rehumidification cylinder 100.

[0032] Once the cleaning equipment reaches the inlet of the rehumidification cylinder 100, it enters the stage of moving into the cylinder. At this point, the power motor mounted on the lower support leg 410, which provides stable support for the machine body 200, is activated. This power motor, as the power source for the equipment's movement, transmits power to the support wheel 411 on the lower support leg 410 via a transmission device. Driven by the power, the support wheel 411 begins to rotate smoothly, causing the entire cleaning equipment to slowly move into the rehumidification cylinder 100.

[0033] As the cleaning equipment gradually penetrates deeper into the rehumidification cylinder 100, adjustments to the equipment's support structure are necessary to ensure stable operation within the cylinder. Operators use control devices to extend the telescopic components 500 between the movable legs 420 and the main body 200. Under power, the telescopic components 500 gradually extend according to a preset program and speed, pushing the movable legs 420 outwards. The support wheels 411 on the movable legs 420 also move towards the inner wall of the rehumidification cylinder 100. With the continuous action of the telescopic components 500, the support wheels 411 on each movable leg 420 eventually come into close contact with the inner wall of the rehumidification cylinder 100. At this point, sufficient friction is generated between the support wheels 411 and the inner wall of the rehumidification cylinder 100, creating a stable circumferential support force for the main body 200 within the cylinder 100. This allows the cleaning equipment to remain securely in its designated position within the cylinder 100, providing reliable support for subsequent cleaning operations.

[0034] Once the cleaning equipment is stably supported within the rehumidification cylinder 100, the cleaning device 300 on the machine body 200 can be activated to officially begin the cleaning operation on the rehumidification cylinder 100. Under the continuous drive of the power motor, the machine body 200 moves slowly along the axis of the rehumidification cylinder 100. The nozzles 310 of the cleaning device 300 are connected to an external water supply system. As the machine body 200 moves, the external water supply system delivers pressurized water to the cleaning device 300. The nozzles 310 of the cleaning device 300 spray the delivered water evenly and powerfully, forming a fine water stream that thoroughly and completely washes the inner wall of the rehumidification cylinder 100. The water stream effectively washes away tobacco residue, dirt, and other impurities adhering to the inner wall of the rehumidification cylinder 100, thereby achieving the purpose of cleaning the rehumidification cylinder 100.

[0035] It is worth mentioning that the entire operation of the aforementioned equipment has significant advantages. Due to the use of this automated cleaning equipment, there is no need for operators to enter the rehumidification cylinder 100 for manual cleaning. The interior space of the rehumidification cylinder 100 is relatively small and may contain adverse environmental factors such as high temperature, humidity, and odors. Manual cleaning is not only labor-intensive but also poses certain safety risks. However, the cleaning equipment in this embodiment can be completely controlled from outside the rehumidification cylinder 100, automatically completing a series of actions such as entry, support, and cleaning. This effectively avoids direct contact between operators and the adverse environment inside the rehumidification cylinder 100, greatly reducing the dangers during the cleaning process. At the same time, the automated cleaning process is more efficient and precise, significantly shortening cleaning time and improving cleaning efficiency, providing strong support for the production and operation of tobacco production enterprises.

[0036] like Figure 2As shown, in some specific embodiments, the telescopic components 500 on each of the movable legs 420 are hinged to the side of the body 200. The body 200 is provided with a first swing motor 210 corresponding to the movable leg 420. The first swing motor 210 is drivenly connected to the telescopic components 500 on the movable leg 420. The first swing motor 210 can drive the movable leg 420 to swing in a plane perpendicular to the axis of the rehumidification cylinder 100. On the one hand, this facilitates flexible adjustment of the relative angle between the movable leg 420 and the body 200 according to actual needs. When the cleaning equipment enters the rehumidification cylinder 100 and prepares to support the body 200, different inner wall shapes and sizes of the rehumidification cylinder 100, as well as the specific location of the equipment, may require the movable leg 420 to present different relative angles with the body 200 to ensure that the movable leg 420 can make good contact with the inner wall of the rehumidification cylinder 100, thereby providing a stable and reliable lateral support force for the body 200. By adjusting the angle of the movable support leg 420 using the first swing motor 210, these diverse needs can be easily met, greatly improving the equipment's adaptability to different rehumidification cylinders 100 and the stability of its support.

[0037] On the other hand, during the movement of the cleaning equipment in the rehumidification cylinder 100, various complex situations may arise. One common obstacle is the rake nails 110 on the inner wall of the rehumidification cylinder 100. These rake nails 110 are typically used to stir and agitate the tobacco leaves inside the rehumidification cylinder 100, but during the movement of the cleaning equipment, they may collide with the movable support legs 420, hindering the normal movement of the equipment and potentially causing damage. The configuration of the first swing motor 210 in this embodiment provides an effective solution to this problem. When the cleaning equipment encounters the rake nails 110 on the inner wall of the rehumidification cylinder 100 during its movement, the operator can issue a command to the first swing motor 210 through the control system. The first swing motor 210 then adjusts the position of the movable support legs 420 via a transmission device. Driven by the first swing motor 210, the movable support leg 420 can swing in a plane perpendicular to the axis of the rehumidification cylinder 100, thereby cleverly avoiding the obstruction of the rake nail 110 and ensuring that the cleaning equipment can continue to move smoothly in the rehumidification cylinder 100. This ensures that the cleaning work in this embodiment can proceed smoothly according to the predetermined plan and will not be interrupted or affected by the obstruction of the rake nail 110 or other obstacles, thus greatly improving the efficiency and reliability of the cleaning work.

[0038] In some specific embodiments, a second swing motor 220 is provided on the swing end of the first swing motor 210. The second swing motor 220 is connected to the telescopic component 500 on the movable leg 420. The second swing motor 220 can drive the movable leg 420 to move towards or away from the axis of the rehumidification cylinder 100. Specifically, when the telescopic component 500 on the movable leg 420, the first swing motor 210, and the second swing motor 220 are combined for comprehensive control, the movement of each movable leg 420 relative to the body 200 can be realized. The telescopic component 500 can change its length as needed, thereby adjusting the distance between the movable leg 420 and the body 200. The first swing motor 210 can drive the movable leg 420 to swing in a plane perpendicular to the axis of the rehumidification cylinder 100, changing the angular position of the movable leg 420 in that plane. The second swing motor 220 further endows the movable leg 420 with the ability to move towards or away from the axis of the rehumidification cylinder 100. By coordinating these three modes of motion, the spatial orientation of the cleaning equipment in this embodiment can be flexibly adjusted according to the actual condition of the rehumidification cylinder 100 and the specific requirements of the cleaning work.

[0039] After the aforementioned series of adjustments, the movable legs 420 can finally form a stable umbrella-shaped support configuration. In this umbrella-shaped support configuration, the direction of the umbrella tip is the same as the water spray direction of the nozzle 310 of the cleaning device 300. During the cleaning process, the nozzle 310 sprays high-pressure water outward to powerfully rinse the inner wall of the rehumidification cylinder 100. However, the high-pressure water spraying out generates a reverse force. If this reaction force is not effectively counteracted, it may cause the cleaning equipment to shake, shift, or even become unstable within the rehumidification cylinder 100, thus seriously affecting the quality and efficiency of the cleaning work. The umbrella-shaped support configuration formed in this embodiment, with its unique structural characteristics, allows each movable leg 420 to evenly distribute and bear the reaction force of the high-pressure water generated during the spraying process of the nozzle 310. The movable support leg 420, like the frame of an umbrella, transmits the reaction force to the entire equipment body 200 and disperses the force onto the rehumidification cylinder 100 through close contact with the inner wall of the rehumidification cylinder 100, thereby ensuring that the cleaning equipment in this embodiment can move stably along the rehumidification cylinder 100.

[0040] This stable movement provides a solid guarantee for the reliable execution of the cleaning work. During stable movement, the nozzles 310 of the cleaning device 300 continuously and evenly rinse the inner wall of the rehumidification cylinder 100, ensuring that every part is thoroughly cleaned, effectively improving the comprehensiveness and thoroughness of the cleaning work. At the same time, stable equipment operation reduces potential damage to the equipment itself caused by shaking or displacement, extending its service life and reducing maintenance costs.

[0041] In some specific embodiments, the support wheels 411 at the ends of the lower support leg 410 and the movable support leg 420 opposite to the body 200 are provided in at least two rows, with multiple support wheels 411 in each row. This multi-row, multi-wheel layout greatly increases the contact area and number of contact points between the support wheels 411 and the inner wall of the rehumidification cylinder 100. When the equipment enters the rehumidification cylinder 100 and performs support operations, the lower support leg 410 and the movable support leg 420 interact with the inner wall of the rehumidification cylinder 100 through these numerous support wheels 411, providing stable and reliable support for the body 200. Even if there is some unevenness on the inner wall of the rehumidification cylinder 100 or if the equipment is subjected to external forces during operation, this multi-row, multi-wheel support structure can effectively disperse the force and avoid instability caused by excessive local stress, ensuring that the machine body 200 remains stable within the rehumidification cylinder 100. Elastic elements 412 are respectively provided between the connecting seat of each support wheel 411 and the end of the lower support leg 410 or the movable support leg 420 away from the machine body 200. When the equipment enters the rehumidification cylinder 100, the inner wall of the rehumidification cylinder 100 may not be perfectly flat, exhibiting certain curvature changes and slight undulations. At this time, the elastic elements 412 can automatically adjust the position and pressure of the support wheels 411 according to the actual shape and surface condition of the inner wall of the rehumidification cylinder 100. When encountering a protruding part of the inner wall, the elastic element 412 is compressed, allowing the support wheel 411 to smoothly pass over the protrusion while maintaining contact with the inner wall. When encountering a concave part of the inner wall, the elastic force of the elastic element 412 pushes the support wheel 411 towards the concave area, ensuring that the support wheel 411 is always tightly fitted to the inner wall. Through this adaptive adjustment method, it can be ensured that each support wheel 411 maintains continuous and good contact with the inner wall of the rehumidification cylinder 100. No matter how complex or varied the shape of the inner wall of the rehumidification cylinder 100 is, it can provide stable and uniform support force, thereby effectively improving the support stability and reliability of the equipment within the rehumidification cylinder 100, and ensuring that the cleaning work can be carried out efficiently and smoothly.

[0042] In some specific embodiments, at least two lower support legs 410 are provided parallel to each other on the body 200 along the axial direction of the rehumidification cylinder 100, so as to enhance the support capacity of the lower support legs 410 for the body 200, reduce the probability of the body 200 tipping over during walking, and ensure the working reliability of this embodiment.

[0043] In some specific embodiments, the body 200 is provided with two auxiliary support legs 430, which are symmetrically arranged on both sides of the lower support leg 410. The plane where the edges of the two lower support legs 410 are located is perpendicular to the axis of the rehumidification cylinder 100. The end of the auxiliary support leg 430 away from the body 200 is provided with a support wheel 411 to provide assistance to the lower support leg 410 and improve the reliability of supporting the body 200.

[0044] In some specific embodiments, the lower support leg 410 and the auxiliary support leg 430 are also provided with telescopic components 500, which facilitates the adjustment of the height of the body 200 and the cleaning device 300 as needed.

[0045] Combination Figure 2 , Figure 3 As shown, in some specific embodiments, the movable support leg 420 is provided with a clamping device 600, which includes a claw 610. The claw 610 is assembled and connected to the movable support leg 420 through the telescopic assembly 500. The claw 610 is assembled and connected to the movable end of the corresponding telescopic assembly 500, and the movable support leg 420 is assembled and connected to the fixed section of the corresponding telescopic assembly 500. The telescopic assembly 500 can drive the claw 610 to move closer to the inner wall of the rehumidification cylinder 100. The device includes a rake nail 110, with a claw 610 for engaging and securing it. A third swing motor 620 is mounted on the movable support leg 420, which is connected to the telescopic assembly 500 corresponding to the claw 610. The third swing motor 620 drives the claw 610 to swing relative to the movable support leg 420. In actual cleaning operations, this clamping device 600 plays a crucial role when encountering stubborn residues on the inner wall of the rehumidification drum 100 that are difficult to remove. The operator can first activate the telescopic assembly 500 connected to the claw 610, causing it to drive the claw 610 towards the rake nail 110. Simultaneously, the third swing motor 620 also starts working, precisely adjusting the swing posture of the claw 610 according to the actual position and angle of the rake nail 110, ensuring that the claw 610 can smoothly approach the rake nail 110 and achieve a secure clamping fixation. Once the claw 610 and rake 110 are secured, a stable support and fulcrum are provided for the cleaning equipment. At this point, the operator can increase the water pressure from the nozzle 310, causing the high-pressure water stream to impact the residue in a targeted pulse manner. This targeted pulse cleaning method concentrates the water flow's power, repeatedly and intensely impacting stubborn residues, thereby effectively improving the cleaning effect on the rehumidification cylinder 100 and ensuring that the inner wall of the rehumidification cylinder 100 is thoroughly cleaned, meeting the high-quality requirements of tobacco production.

[0046] like Figure 4 As shown, in some specific embodiments, the telescopic assembly 500 includes a fixed outer cylinder 510, a telescopic inner cylinder 520, a transmission rod 530, and a telescopic motor 540. The fixed end is located on the fixed outer cylinder 510, and the movable end is located on the telescopic inner cylinder 520. The telescopic inner cylinder 520 is inserted into the fixed outer cylinder 510 via a guide rail. The transmission rod 530 is rotatably mounted on the fixed outer cylinder 510 and inserted into the telescopic inner cylinder 520 via a threaded connection. The telescopic motor 540 is mounted on the fixed outer cylinder 510 and is connected to the transmission rod 530. The telescopic motor 540 drives the transmission rod 530 to rotate relative to the fixed outer cylinder 510, which can drive the telescopic inner cylinder 520 to telescopically move relative to the fixed outer cylinder 510. After the telescopic motor 540 stops working, the telescopic inner cylinder 520 and the fixed outer cylinder 510 can form a self-locking mechanism under the action of threaded engagement, ensuring that the movable support leg 420 or the lower support leg 410 is relatively fixed to the body 200.

[0047] In some specific embodiments, the cleaning device 300 further includes a translation seat 320, a rotating seat 330, and a pitching seat 340. From a structural assembly perspective, the translation seat 320 is mounted on the body 200 in a manner that allows it to move horizontally relative to the body 200. Specifically, the body 200 is provided with a dedicated guide rail or slide rail structure. The translation seat 320 cooperates with the guide rail or slide rail through matching sliders or rollers, thereby achieving smooth horizontal movement. To drive the translation seat 320 to move along the axial direction of the rehumidification cylinder 100, a first adjusting motor is installed on the body 200. The first adjusting motor converts the rotational motion of the motor into the linear motion of the translation seat 320 through a transmission mechanism, such as a lead screw and nut pair or a gear and rack pair. When the first adjusting motor starts and rotates forward or backward according to a preset program or operator's instructions, the translation seat 320 moves forward or backward along the axial direction of the rehumidification cylinder 100, thereby driving subsequent components to adjust their positions in the axial direction.

[0048] The rotating seat 330 is rotatably mounted on the translation seat 320. The translation seat 320 is equipped with bearings or rotary joints, allowing the rotating seat 330 to rotate around a specific axis. To achieve radial rotation of the rotating seat 330 relative to the rehumidification cylinder 100, a second adjusting motor is mounted on the translation seat 320. The second adjusting motor is connected to the rotating seat 330 via a reducer or other transmission components. When the second adjusting motor operates, its output power is transmitted to the rotating seat 330 through the transmission components, driving the rotating seat 330 to rotate within the radial plane of the rehumidification cylinder 100. This rotation allows adjustment of the radial angular position of subsequent components to meet the cleaning needs of different locations on the inner wall of the rehumidification cylinder 100.

[0049] The pitch seat 340 is mounted on the rotating seat 330 via a hinge connection. A hinge shaft is provided on the rotating seat 330, and the pitch seat 340 engages with the hinge shaft through a hinge hole, enabling a pitch-swinging connection. To drive the pitch seat 340 to pitch and swing, a third adjusting motor is provided on the rotating seat 330. The third adjusting motor is connected to the pitch seat 340 via a linkage mechanism or other transmission method. When the third adjusting motor is activated, its movement is transmitted to the pitch seat 340 through a transmission mechanism, causing the pitch seat 340 to pitch and swing up and down around the hinge shaft. The nozzle 310 is mounted on the pitch seat 340. As the pitch seat 340 pitches and swings, the spray angle of the nozzle 310 changes accordingly, thereby enabling precise spray cleaning of different height positions on the inner wall of the rehumidification cylinder 100.

[0050] Furthermore, to further optimize the cleaning process and improve its targeting and effectiveness, a camera 350 is installed on the rotating seat 330. The camera 350 has high-definition shooting capabilities, enabling it to clearly capture real-time images inside the rehumidification cylinder 100. This camera 350 connects to an external control system via wired or wireless means, transmitting the captured image information to the control system in real time. Operators can view the image information transmitted from the camera 350 from the control room via a display screen on the control system. Based on these intuitive images, operators can quickly and accurately grasp the cleaning status inside the rehumidification cylinder 100, such as which areas have been cleaned and which areas still have stubborn residues. Based on these actual conditions, operators can adjust the nozzle 310 in three dimensions as needed. By controlling the first, second, and third adjusting motors, the position of the translation seat 320 in the axial direction, the angle of the rotating seat 330 in the radial direction, and the pitch angle of the pitch seat 340 are adjusted respectively, thereby changing the position and spray direction of the nozzle 310. This reduces blind spots and dead zones during the cleaning process, ensuring that every part of the rehumidification cylinder 100 is thoroughly cleaned, thereby effectively guaranteeing the cleaning quality of the rehumidification cylinder 100 and meeting the high standards required for tobacco production.
