[0023] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] Please see Figure 1 In a first aspect, embodiments of this application provide a drum cleaning device 100, including a support frame 1, a rotary joint 2, a rotary driver 3, and a cleaning assembly 4. The rotary joint 2 has a through-hole cleaning channel 21, which includes a cleaning inlet and a cleaning outlet. The rotary driver 3 is mounted on the support frame 1 and driven by the rotary joint 2. The cleaning assembly 4 includes a cleaning body 41 connected to the rotary joint 2. The cleaning body 41 has a cleaning chamber and a cleaning port 412 communicating with the cleaning chamber. The cleaning chamber is connected to the cleaning outlet. The cleaning inlet is connected to a cleaning medium, allowing the cleaning medium to enter the rotary joint 2. The cleaning medium passes through the cleaning channel of the rotary joint 2 and enters the cleaning chamber of the cleaning body 41, extending the cleaning component into the drum. The cleaning medium can flow out from the cleaning port 412 of the cleaning body 41, cleaning the drum, removing accumulated dirt from the tobacco raw materials, reducing the impact on subsequent tobacco processing, and ensuring the quality of tobacco production. Since the rotary driver 3 can drive the rotary joint 2 to rotate, and the rotary joint 2 drives the cleaning assembly 4 to rotate, under the rotational force of the rotary joint 2, the cleaning medium can flow out from the cleaning port 412 and be thrown towards the inner wall of the drum, which can increase the cleaning area and improve the cleaning efficiency.

[0025] In optional embodiments, the cleaning medium may be water, steam, compressed air, cleaning fluid, etc.

[0026] Please see Figure 1 It should be noted that the rotary joint 2 provided in this embodiment is commercially available, and its internal structure will not be described in detail here. The rotary joint 2 can be a single-channel rotary joint 2 or a multi-channel rotary joint 2, such as a dual-channel rotary joint 2, a three-channel rotary joint 2, or a four-channel rotary joint 2. The number of channels in the rotary joint 2 corresponds to the number of cleaning media. When there is only one type of cleaning media, the rotary joint 2 has one channel; when there are two types of cleaning media, the rotary joint 2 has two channels; and when there are three types of cleaning media, the rotary joint 2 has three channels.

[0027] Please see Figure 1 In some embodiments, the cleaning channel includes a first channel 21, a cleaning inlet including a water inlet, and a cleaning outlet including a water outlet. The water inlet and the water outlet are connected to the first channel 21, and the water outlet is connected to the cleaning chamber.

In other optional embodiments, water can be introduced into the water inlet first, allowing the cleaning body 41 to clean the drum with water. After water cleaning is completed, steam can be introduced into the steam inlet, allowing the cleaning body 41 to clean the drum with steam. Alternatively, steam can be introduced into the steam inlet first, allowing the cleaning body to clean the drum with steam. After steam cleaning is completed, water can be introduced into the water inlet, allowing the cleaning body 41 to clean the drum with water. This application does not limit the order of introducing steam and water; they can be introduced simultaneously or sequentially.

[0032] Please see Figure 1 In an optional embodiment, the cleaning channel includes a first channel 21 and a third channel 23, which are spaced apart. The compressed air inlet and the water inlet are spaced apart, and the compressed air outlet and the water outlet are spaced apart.

[0033] In an optional embodiment, compressed air and water can be simultaneously introduced into the compressed air inlet and water inlet, allowing the cleaning body 41 to simultaneously spray compressed air and water into the drum, cleaning the drum under the combined action of the compressed air and water. In other optional embodiments, water can be introduced into the water inlet first, allowing the cleaning body 41 to clean the drum with water. After water cleaning is completed, compressed air can then be introduced into the compressed air inlet, allowing the cleaning body 41 to clean the drum with compressed air. Alternatively, compressed air can be introduced into the compressed air inlet first, allowing the cleaning body to clean the drum with compressed air. After compressed air cleaning is completed, water can then be introduced into the water inlet, allowing the cleaning body 41 to clean the drum with water. This application does not limit the order of introducing compressed air and water; they can be introduced simultaneously or sequentially.

[0034] Please see Figure 1 In an optional embodiment, the cleaning channel includes a second channel 22 and a third channel 23, which are spaced apart, and the steam inlet and the compressed air inlet are spaced apart, and the steam outlet and the compressed air outlet are spaced apart.

[0035] In an optional embodiment, compressed air and steam can be simultaneously introduced into the compressed air inlet and steam inlet, allowing the cleaning body 41 to simultaneously spray compressed air and steam into the drum, cleaning the drum under the combined action of the compressed air and steam. In other optional embodiments, compressed air can be introduced into the compressed air inlet first, allowing the cleaning body 41 to clean the drum using compressed air. After the compressed air cleaning is completed, steam can be introduced into the steam inlet, allowing the cleaning body 41 to clean the drum using steam. Alternatively, steam can be introduced into the steam inlet first, allowing the cleaning body to clean the drum using steam. After the steam cleaning is completed, compressed air can be introduced into the compressed air inlet, allowing the cleaning body 41 to clean the drum using compressed air. The embodiments of this application do not limit the order of introducing compressed air and steam; they can be introduced simultaneously or sequentially.

[0036] Please see Figure 1 In an optional embodiment, the rotary joint 2 can be a three-channel rotary joint 2, which simultaneously has a first channel 21, a second channel 22, and a third channel 23. The water inlet, steam inlet, and compressed air inlet are spaced apart, as are the water outlet, steam outlet, and compressed air outlet. This application embodiment does not limit the order in which water, compressed air, and steam are introduced; they can be introduced simultaneously or sequentially.

[0037] In an optional embodiment, compressed air, water, and steam can be simultaneously introduced into the compressed air inlet, water inlet, and steam inlet. The cleaning body 41 can simultaneously spray compressed air, water, and steam into the drum, cleaning the drum under the combined action of the compressed air, water, and steam. In other optional embodiments, compressed air can be first introduced into the compressed air inlet, allowing the cleaning body 41 to use compressed air to clean the drum, blowing away the tobacco leaves or shreds inside the drum. Then, water is introduced into the water inlet, allowing the cleaning body 41 to use water to clean the drum. After the drum has been rinsed with water, steam is introduced into the steam inlet, allowing the cleaning body 41 to use steam to clean the drum.

[0038] Please see Figure 1 In some embodiments, the cleaning port 412 includes multiple ports, all of which are spaced apart along the outer peripheral surface of the cleaning component. Providing multiple cleaning ports 412 increases the water outlet area of ​​the cleaning component. When the cleaning component is driven to rotate, water can flow out from the multiple cleaning ports 412 to clean the inner peripheral wall of the drum, thereby increasing the cleaning area and improving cleaning efficiency.

[0039] Please see Figure 1 In an optional implementation, the cleaning port 412 may include two, three, four, five, six, or other numbers.

[0040] Please see Figure 1In an optional embodiment, all cleaning ports 412 may be arranged in an array at intervals along the outer peripheral surface of the cleaning component, or in a spiral arrangement at intervals.

[0041] Please see Figure 1 In some embodiments, the cleaning assembly 4 further includes cleaning blades 42, which are disposed on the outer periphery of the cleaning body 41. The cleaning blades 42 on the outer periphery of the cleaning body 41 increase the contact area between the cleaning body 41 and the drum, enabling the scraping of dirt from the inner wall of the drum. Combined with the rotating rinsing of the water flow, this improves the efficiency of dirt removal.

[0042] Please see Figure 1 In some embodiments, the cleaning blades 42 include multiple blades, which are spaced apart along the outer peripheral surface of the cleaning body 41. Having multiple cleaning blades 42 further increases the contact area between the cleaning blades 42 and the inner wall of the drum.

[0043] In an optional implementation, the number of cleaning blades 42 may include two, three, four, five, six, etc.

[0044] Please see Figure 1 In an optional embodiment, the cleaning blades 42 may be arranged in an array on the outer peripheral surface of the cleaning body 41. Alternatively, the cleaning blades 42 may be arranged in a spiral pattern on the outer peripheral surface of the cleaning body 41.

[0045] In an optional embodiment, the cleaning blade 42 can be made of silicone or cotton cloth, etc.

[0046] Please see Figure 1 In some embodiments, the cleaning body 41 includes a rotating shaft 411 connected to the rotary joint 2. The rotating shaft 411 has a cleaning chamber and a cleaning port 412 along its own axial direction. The length of the rotating shaft 411 in its own axial direction allows it to extend into the inside of the drum for cleaning, and it can adapt to the length of the drum. Under the drive of the rotary driver 3, the rotating shaft 411 is driven to rotate, thereby expanding the cleaning area and improving the cleaning efficiency.

[0047] Please see Figure 1 In an optional embodiment, the cleaning blades 42 are disposed on the outer peripheral surface of the rotating shaft 411 and arranged in an array along the length direction of the rotating shaft 411.

[0048] Please see Figure 1 In an optional embodiment, the cleaning port 412 is provided on the outer peripheral surface of the rotating shaft 411 and arranged in an array along the length direction of the rotating shaft 411.

[0049] Please see Figure 1In some embodiments, the drum cleaning device 100 further includes rollers 5, which are rotatably connected to the bottom of the support frame 1 along its own height direction. The presence of rollers 5 under the support frame 1 improves the mobility of the drum cleaning device 100, allowing it to approach the drum and extend the cleaning assembly 4 into it.

[0050] Please see Figure 1 Secondly, embodiments of this application provide a cleaning system, which includes a drum cleaning device 100 and a drum device 200. The drum cleaning device 100 includes the drum cleaning device 100 as described in the first aspect, and the drum cleaning device 100 is used to clean the drum. This cleaning system has all the technical effects of the drum cleaning device 100, which will not be repeated here.

[0051] Please see Figure 1In some embodiments, the roller device 200 includes a roller support 201, a roller body 202, and a roller motor 203. The roller motor 203 is mounted on the roller support 201, and the roller body 202 is rotatably connected to the roller support 201. The roller motor 203 is driven by the roller body 202, and the roller cleaning device 100 is used to clean the roller body 202. It is understood that the cleaning body 41 of the roller cleaning device 100 can extend into the roller body 202 for cleaning. The roller motor 203 can drive the roller body 202 to rotate in the opposite direction to the rotation direction of the cleaning body 41. When the two rotate in opposite directions, the relative speed between the roller body 202 and the cleaning body 41 is the sum of their rotational speeds. A higher relative speed means a significant increase in the friction frequency and force between the cleaning body 41 and the roller surface, enabling more efficient removal of stains, residues, or attachments from the roller surface. The reverse rotation causes the contact points between the cleaning body 41 and the roller surface to produce staggered motion trajectories. For example, when the drum body 202 rotates clockwise, the cleaning body 41 rotates counterclockwise. The cleaning positions of the cleaning body 41 and the drum body 202 continuously intersect and stagger, avoiding the synchronous sliding phenomenon that may occur when rotating in the same direction. That is, the contact points move in the same direction, which can easily lead to repeated friction in some areas while other areas are not cleaned sufficiently. This staggered trajectory allows the cleaning body 41 to cover the drum surface more evenly, especially targeting the uneven texture, seams, or dead corners of the drum surface, reducing cleaning blind spots caused by uneven contact. The reverse force generated by the reverse rotation will have a tearing effect on the adhering substances on the surface of the drum body 202. Sticky stains on the drum body 202 may move synchronously with the drum when rotating in the forward direction, but the reverse rotation of the cleaning body 41 will apply a reverse pulling force to the stains, accelerating their removal from the surface of the drum body 202. At the same time, the vortex or airflow generated by the reverse rotation can more effectively push the removed stains and impurities towards the discharge port, reducing the secondary adhesion of stains between the drum body 202 and the cleaning body 41, and improving the cleanliness after cleaning.
