[0002] In the tobacco processing production process, many pieces of equipment in the processing equipment use roller devices. The rotation of the roller device enables the material to spiral forward inside the roller, while water, feed, or heating operations are performed to make the material uniform.
[0003] In the tobacco drying process, the drum unit heats the drum wall through steam condensation, thereby drying the tobacco with high moisture content. However, over long-term operation, scale buildup on the inner wall of the drum can reduce heat transfer efficiency, affecting drying performance and product quality. Summary of the Invention

[0014] The rolling cylinder is rotatably disposed in the mounting groove around its own axis and has a second mating structure;
[0015] In this configuration, one of the first and second mating structures is a slide rail groove arranged around the axis of the rolling cylinder, and the other is a raised slide rail arranged around the axis of the rolling cylinder. The slide rail groove and the raised slide rail are in sliding engagement.
[0016] In one embodiment, the rolling drum has an inlet and an outlet at its two ends in the axial direction, respectively;
[0017] The roller device further includes a mounting shell and two connecting plates; the mounting shell is disposed on the base and covers the roller; the two connecting plates connect the mounting shell, one of the connecting plates being at least partially located at the feed inlet, and the other connecting plate being at least partially located at the discharge outlet;

[0036] Please refer to Figures 1 to 4. An embodiment of this application provides a cleaning assembly 100 for cleaning a roller device 200, and includes a rotating tube 10 and a first drive mechanism 30. The rotating tube 10 includes a tube body 11 and a nozzle 13. The tube body 11 has a pipe 111 inside, and the nozzle 13 is disposed on the periphery of the tube body 11 and communicates with the pipe 111. The first drive mechanism 30 is drively connected to the rotating tube 10 and is configured to drive the rotating tube 10 to rotate about a first direction (the X direction as shown in Figure 4), and the first direction is configured to intersect the orientation of the nozzle 13.
[0037] Understandably, pipe 111 is used to supply cleaning water, which can flow along pipe 111 and be sprayed out from nozzle 13. The orientation of nozzle 13 is the direction in which the cleaning water is sprayed out from nozzle 13.
[0038] The first drive mechanism 30 can drive the rotating tube 10 to rotate, and the rotation axis is parallel to the first direction and intersects the orientation of the nozzle 13. During the rotation of the rotating tube 10, the orientation of the nozzle 13 changes continuously. The first drive mechanism 30 can be, but is not limited to, a motor.
[0039] The aforementioned cleaning assembly 100 has a pipe 111 through which cleaning water is introduced, and the cleaning water is sprayed from the nozzle 13 onto the inner wall of the rotating drum 210 of the drum device 200 to rinse away residue on the inner wall of the rotating drum 210. Furthermore, the first drive mechanism 30 can also drive the rotating tube 10 to rotate, continuously changing the position of the nozzle 13 for rinsing, thus achieving a more thorough cleaning of the inner wall of the rotating drum 210. In this way, users can use the cleaning assembly 100 to clean the rotating drum 210 in a timely manner, alleviating scaling on the inner wall of the rotating drum 210 and reducing the problem of decreased heat transfer efficiency caused by scaling.
[0040] Specifically, the pipe body 11 is configured with its axis along a first direction, and the first drive mechanism 30 is configured to drive the rotating pipe 10 to rotate about the axis of the pipe body 11. Understandably, the pipe 111 may also extend along the first direction, and the nozzle 13 may be oriented perpendicular to the first direction.
[0041] In this way, the rotating tube 10 can rotate more smoothly under the drive of the first drive mechanism 30.
[0042] In some embodiments, the rotating tube 10 includes at least two nozzles 13, and at least some of the nozzles 13 are spaced apart in a first direction.
[0043] In this way, the rotating tube 10 can spray cleaning water to different positions on the inner wall of the rotating drum 210 in the first direction through different nozzles 13, thereby improving the cleaning coverage of the cleaning assembly 100.
[0044] In one embodiment, the rotating tube 10 includes at least four nozzles 13, all of which are divided into at least two nozzle groups, each of which includes at least two nozzles 13. All nozzle groups are arranged sequentially at intervals along the longitudinal direction of the tube body 11, and all nozzles 13 in each nozzle group are evenly arranged around the tube body 11.
[0045] In this way, the cleaning water sprayed from the nozzle 13 can cover a larger area and be more evenly distributed.
[0046] In some embodiments, the cleaning assembly 100 further includes a water pump 50, the outlet of which is connected to a conduit 111.
[0047] Understandably, the water pump 50 can be connected to an external water source and draw water from the external water source to deliver it to the pipe 111 as a cleaning water pump, and spray it out through the nozzle 13.
[0048] In this way, the water pump 50 can provide the flow and spray power of the cleaning water, which helps to reduce the water intake conditions and improve the cleaning effect.
[0049] Furthermore, the cleaning assembly 100 also includes a connecting pipe 70, one end of which is connected to the outlet of the water pump 50, and the other end is rotatably connected to the pipe body 11 and connected to the pipe 111.
[0050] In this way, the connecting pipe 70 can deliver clean water from the water pump 50 to the pipe 111 of the pipe body 11 without affecting the rotation of the rotating pipe 10.
[0051] Specifically, a dynamic seal can be formed at the connection between the rotating pipe 10 and the pipe body 11 to reduce the probability of water leakage at the connection.
[0052] In some other embodiments, the pipe 111 may also be directly connected to an external water source with driving water pressure, such as tap water, and the water flow is driven by the water pressure of the water source itself. No specific limitation is made here.
[0053] This application also provides a roller device 200, including a roller drum 210 and the aforementioned cleaning assembly 100. The rotating tube 10 is detachably disposed inside the roller drum 210, and the nozzle 13 faces the inner wall of the roller drum 210.
[0054] In one embodiment, the roller device 200 is used in the tobacco leaf processing process and can utilize steam condensation on the outer wall of the roller drum 210 to dry the tobacco leaves inside.
[0055] In addition, the rotating tube 10 can be coaxially arranged with the rolling cylinder 210 and spaced apart from the rolling cylinder 210, that is, the rotating tube 10 is suspended relative to the rolling cylinder 210 inside the rolling cylinder 210 and does not come into contact with the rolling cylinder 210.
[0056] The aforementioned roller device 200 can install the rotating tube 10 inside the roller drum 210 when it is necessary to clean the inner wall of the roller drum 210, and can remove the rotating tube 10 when the roller device 200 is performing normal drying or other operations.
[0057] In some embodiments, the roller device 200 further includes a base 230 on which the roller 210 is rotatably disposed about its own axis. The base 230 has a placement groove 231 configured to accommodate the removed rotating tube 10.
[0058] Thus, the base 230 is used to support the rolling cylinder 210, and the rolling cylinder 210 can roll on the base 230. The base 230 is provided with a placement groove 231, which can store the disassembled rotating tube 10 for easy use next time.
[0059] In some embodiments, the base 230 has a mounting groove 233, and the groove wall of the mounting groove 233 is provided with a first mating structure 235. The rolling cylinder 210 is rotatably disposed in the mounting groove 233 about its own axis and has a second mating structure 211.
[0060] Among them, one of the first mating structure 235 and the second mating structure 211 is a slide rail groove arranged around the axis of the rolling cylinder 210, and the other is a raised slide rail arranged around the axis of the rolling cylinder 210. The slide rail groove and the raised slide rail are in sliding fit.
[0061] Thus, the cooperation between the slide rail groove and the raised slide rail allows the rolling cylinder 210 to rotate relative to the base 230 around its own axis, while restricting its movement relative to the base 230 along the axis, which helps to improve the stability of rotation.
[0062] In one embodiment, the first mating structure 235 is a slide rail groove, and the second mating structure 211 is a raised slide rail. In other embodiments, the first mating structure 235 may also be a raised slide rail, and the second mating structure 211 may be a slide rail groove.
[0063] In some embodiments, the roller device 200 further includes a second drive mechanism 250, which is drively connected to the roller drum 210 and configured to drive the roller drum 210 to rotate about its own axis in a first direction. The first drive is configured to drive the rotating tube 10 to rotate about a first direction in a second direction, the second direction being opposite to the first direction.
[0064] Thus, the rolling drum 210 and the rotating tube 10 can rotate in opposite directions under the drive of the first drive mechanism 30 and the second drive mechanism 250, which helps to improve the rinsing effect of the cleaning assembly 100 and improve the cleaning efficiency.
[0065] Furthermore, the second drive mechanism 250 includes a roller motor 251, a first pulley 253, and a second pulley 255. The first pulley 253 is located at the output end of the roller motor 251, and the second pulley 255 is sleeved on the outer periphery of the feed inlet 213 or the discharge outlet 215. The first pulley 253 and the second pulley 255 are connected by a belt drive. The roller motor 251 can be, but is not limited to, a servo motor, and can be mounted on the base 230.
[0066] In this way, the drum motor 251 can output power and drive the drum 210 to rotate smoothly through the first pulley 253 and the second pulley 255.
[0067] In some embodiments, the rotating drum 210 has an inlet 213 and an outlet 215 at its two ends in the axial direction. The drum device 200 also includes a spiral plate 217, which is disposed inside the rotating drum 210 and whose spiral axis coincides with the axis of the rotating drum 210. This allows the tobacco to be discharged by controlling the drum motor 251 to rotate forward or backward. At the same time, in order to realize the assembly of the cleaning component 100, a clearance notch is also required in the center of the spiral plate 217 for the rotating tube 10 to pass through.
[0068] Thus, the rotating drum 210 can be fed with material through the feed inlet 213 and discharged through the discharge outlet 215. The second drive mechanism 250 drives the rotating drum 210 to rotate, which in turn allows the spiral plate 217 to push the tobacco out.
[0069] In some embodiments, the roller assembly 200 further includes a mounting housing 270 and two connecting plates 290. The mounting housing 270 is disposed on the base 230 and covers the roller 210. The two connecting plates 290 connect the mounting housing 270, with one connecting plate 290 at least partially located at the feed inlet 213 and the other connecting plate 290 at least partially located at the discharge outlet 215.
[0070] The rotating tube 10 passes through the rolling cylinder 210 and is rotatably connected to two connecting plates 290 at its two ends in the first direction.
[0071] Thus, the rotating tube 10 can be suspended inside the rolling drum 210 through the connecting plate 290, which facilitates the cleaning of the inner wall of the rolling drum 210 and the disassembly and assembly of the rolling drum 210.
[0072] Specifically, the rotating tube 10 can be disassembled and assembled together with the second connecting plate 293. Simply by turning the bolts, the second connecting plate 293 can be removed from the rotating tube 10 and placed in the placement slot 231.
[0073] In one embodiment, each connecting plate 290 includes a first connecting plate 291 and a second connecting plate 293. The first connecting plate 291 is L-shaped, with one end connected to the mounting housing 270 and the other end extending to the inlet 213 or outlet 215 of the rotating drum 210. The second connecting plate 293 is bolted to the bottom of the first connecting plate 291, which faces upwards from the inlet 213 or outlet 215. The water pump 50 and the first drive mechanism 30 can be respectively mounted on the two connecting plates 290 and correspondingly cooperate with the rotating tube 10.
[0074] In some other embodiments, the connecting plate 290 can also be connected to the base 230. As long as the two connecting plates 290 can extend to the feed port 213 and the discharge port 215 respectively, so that the rotating tube 10 can be rotatably connected to achieve the suspended setting in the rolling drum 210, no specific limitation is made here.
[0075] In some embodiments, the roller device 200 further includes a controller 2110, which is electrically connected to and controls the operation of at least one of the first drive mechanism 30, the second drive mechanism 250, and the water pump 50.
[0076] The aforementioned roller device 200 has a mounting groove 233 on the upper surface of the base 230, and symmetrical slide rail grooves are formed on the inner wall of the mounting groove 233. The roller 210 is shaped and sized to fit the mounting groove 233, is rotatably mounted in the mounting groove 233, and has raised slide rails of the same shape and size as the slide rail grooves, which slide in cooperation with the slide rail grooves. A mounting shell 270 is provided on the upper surface of the base 230, and a connecting plate 290 is connected to the mounting shell 270. The roller 210 has an inlet 213 and an outlet 215 at both ends, and two connecting plates 290 are respectively connected to the two ends of the mounting shell 270 in a first direction, and each connecting plate 290 includes a first connecting plate 291 and a second connecting plate 293. The first connecting plate 291 is L-shaped, with one end connected to the mounting shell 270 and the other end extending to the inlet 213 or outlet 215 of the rotating drum 210. It is bolted to the bottom of the second connecting plate 293, which faces upwards from the inlet 213 or outlet 215. A water pump 50 is located on one side of the second connecting plate 293 located at the inlet 213. A first drive mechanism 30 is located on one side of the second connecting plate 293 located at the outlet 215. A rotating tube 10 is located between the two second connecting plates 293 and forms a rotatable connection with the second connecting plates 293 at both ends, allowing rotation around a first direction. The rotating tube 10 has several nozzles 13 on its circumferential side of the tube body 11, and one end is fixedly connected to the output end of the first drive mechanism 30. The rotating tube 10 can be disassembled and assembled together with the second connecting plate 293, and the base 230 has a placement groove 231, which can accommodate the disassembled rotating tube 10 and the second connecting plate 293. In addition, a connecting tube 70 is provided at the bottom of the water pump 50, and the free end of the connecting tube 70 is rotatably connected to and communicates with one end of the rotating tube 10. The water pump 50 is connected to an external water source, and the controller 2110 is electrically connected to an external power source. The controller 2110 is also electrically connected to the first drive mechanism 30, the drum motor 251, and the water pump 50, and controls their operation.
[0077] Thus, the roller device 200 can start the roller motor 251 to drive the first pulley 253 at the output end to rotate. The first pulley 253 drives the second pulley 255 to rotate via a belt. The roller drum 210 can be driven to rotate by the second pulley 255 through the cooperation of the raised slide rail and the slide rail groove. Through the spiral plate 217 provided on the inner wall of the roller drum 210, the tobacco can be discharged by controlling the roller motor 251 to rotate forward or backward. When it is necessary to clean the inside of the drum 210, the second connecting plate 293 and the rotating tube 10 placed in the placement slot 231 are taken out and installed on the first connecting plate 291. Then, the water pump 50 connects to an external water source and sends water through the connecting pipe 70 into the pipe 111 of the rotating tube 10. The water is then sprayed out by the nozzle 13 to rinse the residue on the inner wall of the drum 210. Then, the first drive mechanism 30 is activated to drive the rotating tube 10 to rotate, thereby achieving all-round rinsing of the inner wall of the drum 210. Finally, the drum motor 251 drives the drum 210 and the first drive mechanism 30 to drive the rotating tube 10 to rotate in opposite directions, thereby better cleaning the inner wall of the drum 210.
[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0079] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
