Description

Technical Field

[0001] This application relates to the technical field of tobacco stem processing equipment, and in particular to a cleaning device for a tobacco stem heating and humidifying machine. Background Technology

[0002] In the cigarette manufacturing process, the tobacco stems require heating and humidification treatment, which is accomplished using a tobacco stem heating and humidification machine. This machine includes an outer casing with a rotating shaft inside. Multiple levers are radially arranged around the outer circumference of the shaft. A drive motor is also located outside the casing, with its output coaxially connected to the rotating shaft. Driven by the motor, the shaft rotates, causing the levers to rotate as well. This places the tobacco stems inside the casing, and high-temperature steam is introduced into the casing. The rotating levers continuously agitate the tobacco stems, thus heating and humidifying them. However, with prolonged operation of the tobacco stem heating and humidification machine, tobacco residue accumulates inside the casing, especially on the levers. Currently, the method of cleaning this residue is manual with water pipes, which is ineffective, incomplete, time-consuming, and labor-intensive. Utility Model Content

[0003] The purpose of this application is to provide a cleaning device for a tobacco stem heating and humidifying machine, which can conveniently and quickly clean the inside of the heating and humidifying machine, thereby effectively solving the shortcomings of the prior art.

[0004] Therefore, this application provides a cleaning device for a tobacco stem heating and humidifying machine, comprising:

[0005] shell;

[0006] The rotating shaft has a hollow cylindrical structure with an internal cavity, and the rotating shaft is rotatably mounted on the outer shell;

[0007] The lever is a hollow cylindrical structure with an internal cavity. There are multiple levers, which are connected to the outer periphery of the rotating shaft, and the internal cavities of the levers are connected to the internal cavities of the rotating shaft.

[0008] The lever has multiple spray holes on its outer periphery, and the spray holes are connected to the internal cavity of the lever.

[0009] In some possible implementations, the lever is an elongated component with one end open and the other end closed, the closed end of which is connected to the outer periphery of the rotating shaft.

[0010] In some possible implementations, the length direction of the lever is the radial extension direction of the shaft.

[0011] In some possible implementations, the levers are arranged in multiple rows on the rotating shaft, with multiple levers in each row.

[0012] In some possible implementations, the arrangement direction of each row of levers on the rotating shaft is parallel to the axial direction of the rotating shaft.

[0013] In some possible implementations, the multiple levers on the rotating shaft are arranged in a spiral pattern.

[0014] In some possible implementations, the open end of the lever is detachably connected to the outer periphery of the shaft.

[0015] In some possible implementations, the open end of the lever and the outer periphery of the shaft are connected to each other by a threaded connection.

[0016] In some possible implementations, a transition tube is also included, with one end of the shaft extending out of the housing, and that end of the shaft being rotatably connected to one end of the transition tube.

[0017] In some possible implementations, the housing is provided with an access door that can open or close the housing.

[0018] According to the cleaning device for the tobacco stem heating and humidifying machine provided in the embodiments of this application, both the rotating shaft and the lever are hollow cylindrical structures. The lever is set on the outside of the rotating shaft. The rotating shaft drives the lever to rotate and introduces high-temperature steam into the interior of the outer shell, thereby realizing the heating and humidifying treatment of tobacco stems by the heating and humidifying machine. When it is necessary to clean the inside of the outer shell, the rotating shaft, and the outer surface of the lever with tobacco residue, the rotating shaft is connected to other water supply pipes, so that water is sprayed out from the nozzles on the lever, thereby realizing the cleaning of tobacco residue in the interior space of the outer shell, making the cleaning more thorough and convenient.

[0020] Figure 2 for Figure 1 A magnified view of a portion of point A in the middle. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] like Figures 1-2 As shown in the illustration, this application provides a cleaning device for a tobacco stem heating and humidifying machine, used for cleaning the interior of the machine. During production, cigarette factories need to heat and humidify the tobacco stems. The tobacco stem heating and humidifying machine typically includes an outer casing. Inside the casing is a rotating shaft 200, and outside the casing is a drive motor 400 connected to the rotating shaft 200, thus driving the shaft 200 to rotate. Radially extending levers 300 are also provided around the outer periphery of the rotating shaft 200. Multiple levers 300 are arranged in an array. When heating and humidifying the tobacco stems is required, the tobacco stems are fed into the outer casing. High-temperature steam is introduced into the outer casing, and the rotating shaft 200 drives the lever 300 to rotate, causing the lever 300 to turn the tobacco stems, thereby increasing the temperature and humidity of the tobacco stems. In practice, it has been found that with the long-term operation of the heating and humidifying machine, a lot of tobacco residue will be generated inside the outer casing 100 and on components such as the lever 300. Currently, the method for dealing with tobacco residue is manual, with operators holding water hoses to clean the tobacco residue inside. The entire cleaning process is time-consuming, has poor cleaning effect, and is labor-intensive for operators. The tobacco stem heating and humidifying machine cleaning device of this application aims to improve the convenience of cleaning the inside of the heating and humidifying machine.

[0023] The tobacco stem heating and humidifying cleaning device includes a housing 100, a rotating shaft 200, and a lever 300. The housing 100 encloses an internal cavity, and the rotating shaft 200 is located within the internal cavity of the housing 100. Both ends of the rotating shaft 200 extend out of the housing 100. A portion of the area near both ends of the rotating shaft 200 is rotatably connected to the housing 100 via bearings. The rotating shaft 200 is a hollow cylindrical structure with an internal cavity. One end of the rotating shaft 200 is a sealed end, and the other end is an open end. Both the open and sealed ends of the rotating shaft 200 extend outward from the housing 100. A drive motor 400 is installed outside the housing 100, and the drive motor 400 is connected to the sealed end of the rotating shaft 200, thereby driving the rotating shaft 200 to rotate. The lever 300 is also a hollow cylindrical structure with an internal cavity. The device comprises multiple levers 300 connected to the outer periphery of the rotating shaft 200, with the internal cavities of the levers 300 and the rotating shaft 200 communicating with each other. Furthermore, multiple nozzles 301 are provided on the outer periphery of the levers 300, and these nozzles 301 communicate with the internal cavities of the levers 300. Thus, when cleaning the interior of the outer casing 100 is required, a pressurized water supply pipe is connected to the open end of the rotating shaft 200, allowing water to be sprayed from the nozzles 301 on the levers 300. This provides comprehensive spray cleaning of the inner wall of the outer casing 100 and the outer wall of the levers 300, significantly improving the cleaning effect. Compared to manually holding a water hose, the cleaning device provided in this application offers higher cleaning efficiency, lower labor intensity, and more thorough cleaning, significantly reducing cleaning time and improving equipment operating efficiency.

[0024] Furthermore, the hollow rotating shaft 200 and lever 300 enable the cleaning device to be used in multiple ways. On the one hand, when heating and humidifying the tobacco stems, after the tobacco stems are sent into the outer casing 100, a high-temperature steam pipe can be connected to the open end of the rotating shaft 200. Steam is sprayed out from the nozzle 301 of the lever 300, while the tobacco stems are being turned over and heated and humidified. When it is necessary to clean the interior space of the outer casing 100, the steam pipe at the open end of the rotating shaft 200 can be replaced with a water pipe, so that water is sprayed out from the nozzle 301 of the lever 300, thereby cleaning the interior of the outer casing 100. This multi-purpose design makes the device more convenient to use.

[0025] More preferably, the lever 300 is an elongated component with one end open and the other end closed. The closed end of the lever 300 is connected to the outer periphery of the rotating shaft 200. In this embodiment, the lever 300 has a long cylindrical structure with one end open and the other end closed. The spray nozzle 301 is spirally arranged on the outer periphery of the lever 300. In this way, when water is sprayed, the space inside the outer shell 100 can be cleaned more comprehensively and thoroughly. In this embodiment, the length direction of the lever 300 is the radial extension direction of the rotating shaft 200. That is, the lever 300 is connected to the outer periphery of the rotating shaft 200 along the radial direction of the rotating shaft 200, so that the levers 300 on the outer periphery of the rotating shaft 200 are distributed in a divergent manner, which is conducive to cleaning the interior of the outer shell 100 comprehensively.

[0026] In some embodiments, the levers 300 are arranged in multiple rows on the outer periphery of the rotating shaft 200, with multiple levers 300 in each row, to facilitate comprehensive cleaning. More preferably, the arrangement direction of each row of levers 300 on the rotating shaft 200 is parallel to the axial direction of the rotating shaft 200. Multiple rows of levers 300 are arranged along the circumference of the rotating shaft 200, with the arrangement direction of each row of levers 300 being the axial direction of the rotating shaft 200. This allows for more comprehensive turning of the tobacco stems during heating and humidification, and also enables more comprehensive cleaning during water jet cleaning. More preferably, the multiple levers 300 on the rotating shaft 200 are arranged in a spiral pattern, that is, all levers 300 are spirally distributed on the outer periphery of the rotating shaft 200, which also facilitates comprehensive cleaning of the inner wall of the outer casing 100, each lever 300, and the rotating shaft 200.

[0027] In a preferred embodiment, the open end of the lever 300 is detachably connected to the outer periphery of the rotating shaft 200, facilitating disassembly, inspection, and replacement of the lever 300. For example, the open end of the lever 300 and the outer periphery of the rotating shaft 200 are connected to each other by a threaded connection. In this embodiment, a mounting hole 201 is provided on the outer wall of the rotating shaft 200, which communicates with the internal space of the rotating shaft 200. The mounting hole 201 is provided with an internal thread, and an external thread is provided on the outer wall of the open section of the lever 300. By screwing the open end of the lever 300 to the mounting hole 201... The lever 300 is installed in the hole 201, which is convenient and has a high sealing performance. More preferably, a boss 202 is provided on the outer wall of the rotating shaft 200 at the position corresponding to the mounting hole 201 and coaxial with the mounting hole 201. The mounting hole 201 passes through the boss 202 and the outer wall of the rotating shaft 200, so that the outer wall of the rotating shaft 200 forms a thickened structure at the mounting hole 201. The open end of the lever 300, the boss 202 and the outer wall of the rotating shaft 200 are all threadedly connected. In this way, the connection and engagement length with the lever 300 is increased, and the connection strength and sealing performance are improved.

[0028] In some embodiments, a transition pipe 500 is also included. One open end of the rotating shaft 200 extends out of the outer casing 100, and this extended end of the rotating shaft 200 is rotatably connected to one end of the transition pipe 500. In this embodiment, the end of the rotating shaft 200 extends into the end of the transition pipe 500. A polytetrafluoroethylene (PTFE) sealing gasket can be provided between the outer wall of the rotating shaft 200 and the inner wall of the transition pipe 500, so that the rotating shaft 200 and the transition pipe 500 can rotate relative to each other while also achieving a seal. This seal is sufficient to prevent leakage of water or steam. The other end of the transition pipe 500 is used to connect to a steam pipe or water supply. The pipe connection allows the rotating shaft 200 to rotate while steam or water is introduced into it. During cleaning, the rotating shaft 200 drives the lever 300 to rotate while spraying water, resulting in a more comprehensive and thorough cleaning of the interior. In addition, the rotation of the lever 300 driven by the rotating shaft 200 enables multi-directional changes in the water spray for comprehensive cleaning. Furthermore, when there is a certain amount of water inside the outer casing 100, the rotating shaft 200 drives the lever 300 to repeatedly enter and exit the water, constantly agitating the water surface, which also achieves the same cleaning effect.

[0029] Preferably, an inspection door 600 can also be provided on the outer casing 100. The inspection door 600 can open or close the outer casing 100. The inspection door 600 can close the outer casing 100 for sealing, and the inspection door 600 can also open the outer casing 100. This facilitates the maintenance of internal components and the removal of internal impurities. A drain pipe 700 can also be provided on the outer casing 100. A valve is provided on the drain pipe 700 to facilitate the timely discharge of wastewater generated when cleaning the inside of the outer casing 100.
