Technical Field

[0001] This application relates to the field of cigarette equipment technology, and in particular to a nozzle adjustment device and a tobacco rehydration machine. Background Technology

[0002] In the process of producing expanded tobacco, cooling and rehumidification are essential steps. The rehumidification system is used to cool and rehumidify the expanded tobacco after it has been treated by the sublimation device, restoring it to the required moisture content to meet the requirements for tobacco storage and blending. Water nozzles inside the rehumidification machine rotate synchronously with the drum, thereby humidifying the tobacco material.

[0003] Currently, to ensure the uniformity of humidification, the rehumidifier is designed with multiple water nozzles inside the cylinder. Typically, the humidifying nozzles inside the rehumidifier are installed on the built-in spray plate and arranged in three zones along the axial direction of the cylinder, with three humidifying nozzles in each zone. The spray plate is fixed and has a large area. After production, a large amount of tobacco shreds and ash residue remains on the spray plate and inside the cylinder, weighing more than 10 kg, reducing the utilization rate of materials.

Detailed Implementation

[0039] 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.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0045] Understandably, cooling and rehydration are essential steps in the tobacco expansion process. The rehydration system is used to cool and rehydrate the expanded tobacco after it has been treated by the sublimation device, restoring it to the required moisture content to meet the needs of tobacco storage and blending. Water nozzles inside the rehydration machine rotate synchronously with the drum, thus humidifying the tobacco material.

[0046] Currently, to ensure the uniformity of humidification, the rehumidifier is designed with multiple water nozzles inside the cylinder. Typically, the humidifying nozzles inside the rehumidifier are installed on the built-in spray plate and arranged in three zones along the axial direction of the cylinder, with three humidifying nozzles in each zone. The spray plate is fixed and has a large area. After production, a large amount of tobacco shreds and ash residue remains on the spray plate and inside the cylinder, weighing more than 10 kg, reducing the utilization rate of materials.

[0047] See Figure 1 and Figure 2This application provides a nozzle adjusting device 100. The nozzle adjusting device 100 can be applied to a silk rehydration machine 10. Figure 1 This is a schematic diagram of a nozzle adjusting device 100 according to an embodiment of this application. Figure 2 for Figure 1 The diagram shows the nozzle adjusting device 100 applied to the silk rehydration machine 10. Of course, in other embodiments of this application, the nozzle adjusting device 100 can also be applied to other devices or equipment that require the use of nozzles. This application only uses the application of the nozzle adjusting device 100 to the silk rehydration machine 10 as an example for illustration.

[0048] Understandably, the tobacco rehydration machine 10 is a piece of equipment in the tobacco expansion process of cigarette production. It is mainly used to cool and rehydrate materials such as tobacco to bring them back to the required moisture content for the process. To better illustrate the structure of the nozzle adjustment device 100, this application will first briefly introduce the structure of the tobacco rehydration machine 10.

[0049] See Figure 1 and Figure 2 The tobacco rehydration machine 10 includes a drum 200 and the nozzle adjustment device 100 of this application. The nozzle adjustment device 100 is disposed in the drum 200. After the tobacco material enters the drum 200, the nozzle adjustment device 100 can spray the tobacco material to humidify it so that the tobacco material is rehydrated to the moisture content required by the process.

[0050] The position of the nozzle adjusting device 100 within the drum 200 is adjustable to meet water spraying requirements in different directions. The drum 200 has a hollow cylindrical structure and has an inlet end 230 and an outlet end 240 along its axial direction. Tobacco material enters the drum 200 from the inlet end 230, and the nozzle adjusting device 100 sprays the tobacco material to humidify it. The humidified tobacco material exits the drum 200 through the outlet end 240.

[0051] It is worth noting that the axial and radial directions in this application are based on the roller 200. The direction of the central axis of the roller 200 is the axial direction (front-to-back direction) of the roller 200, and the radial direction (lateral and longitudinal directions) of the roller 200 is the radial direction (lateral and longitudinal directions). The lateral, longitudinal, and front-to-back directions are as follows: Figure 1 and Figure 2 As shown, the nozzle adjusting device 100 extends in the transverse, longitudinal, and front-back directions. The axial and radial directions in this application are based on the roller 200, and will not be described further below.

[0052] See Figure 1 and Figure 2In one embodiment of this application, the roller 200 includes an inner cylinder 210 and an outer cylinder 220. The inner cylinder 210 is disposed within the outer cylinder 220, and the outer cylinder 220 is rotatable relative to the inner cylinder 210. One end of the inner cylinder 210 is the inlet end 230, and the end of the outer cylinder 220 away from the inner cylinder 210 is the outlet end 240. There is one nozzle adjusting device 100, which is disposed within the inner cylinder 210 and near the inlet end 230. The nozzle adjusting device 100 is movable along the axial direction of the inner cylinder 210.

[0053] The inner cylinder 210 is located within the outer cylinder 220, and there is a certain distance between the inner cylinder 210 and the outer cylinder 220 along the radial direction of the roller 200. Furthermore, the axial dimension of the inner cylinder 210 is smaller than the axial dimension of the outer cylinder 220. The outer cylinder 220 can rotate around the inner cylinder 210; that is, the inner cylinder 210 remains stationary while the outer cylinder 220 rotates. The nozzle adjusting device 100 is disposed within the inner cylinder 210 and can move axially along the roller 200 to adjust the position of the nozzle adjusting device 100 within the inner cylinder 210.

[0054] The tobacco material enters the inner cylinder 210 through the inlet end 230. Then, the nozzle adjusting device 100 sprays the tobacco material to humidify it. The tobacco material then enters the outer cylinder 220. When the outer cylinder 220 rotates, it causes the tobacco material to rotate within its inner cavity, ensuring uniform mixing. Finally, the humidified tobacco material exits the outer cylinder 220 through the outlet end 240 into the roller 200.

[0055] In this embodiment, a nozzle adjusting device 100 is provided in the stationary inner cylinder 210, and the position of the nozzle adjusting device 100 in the inner cylinder 210 is adjusted. The tobacco material is sprayed by the nozzle adjusting device 100, and the tobacco material is mixed evenly by the rotating outer cylinder 220, thereby ensuring that the tobacco material is evenly distributed, improving the moisture regain effect of the tobacco material, and ensuring the stability of the cigarette product quality.

[0056] In another embodiment of this application, the roller 200 includes an inner cylinder 210 and an outer cylinder 220. The inner cylinder 210 is disposed within the outer cylinder 220, and the outer cylinder 220 is rotatable relative to the inner cylinder 210. One end of the inner cylinder 210 is the inlet end 230, and the end of the outer cylinder 220 away from the inner cylinder 210 is the outlet end 240. There are two nozzle adjusting devices 100, one of which is disposed within the inner cylinder 210 and near the inlet end 230, and the other is disposed within the outer cylinder 220 and near the outlet end 240.

[0057] In other words, there can be two nozzle adjusting devices 100. One nozzle adjusting device 100 is located on the inner wall of the inner cylinder 210, near the inlet end 230, and the other nozzle adjusting device 100 is located on the inner wall of the outer cylinder 220, near the outlet end 240. In this way, the other nozzle adjusting device 100 can spray the tobacco material at the outlet end 240 to replenish water, thereby ensuring the re-moistening effect of the tobacco material.

[0058] Of course, in other embodiments of this application, the number of nozzle adjusting devices 100 may be three or other numbers, with one nozzle adjusting device 100 provided in the inner cylinder 210 and at least two nozzle adjusting devices 100 provided in the outer cylinder 220.

[0059] It is worth noting that the nozzle adjusting device 100 installed in the inner cylinder 210 and the nozzle adjusting device 100 installed in the outer cylinder 220 have essentially the same structure and working principle. This application only uses the example of the nozzle adjusting device 100 being installed on the inner wall of the roller 200 for illustration. Figure 1 and Figure 2 In the diagram, the nozzle adjusting device 100 is actually located on the inner wall of the inner cylinder 210, while the nozzle adjusting device 100 is located on the inner wall of the outer cylinder 220, which is not shown.

[0060] The nozzle adjusting device 100 of this application has an adjustable position within the roller 200 to meet the needs of water spraying in different directions, ensuring uniform moisture content in the output tobacco material, improving the rehydration effect of the tobacco material, ensuring stable quality of cigarette products, and simultaneously reducing the area of ​​the nozzle assembly 130, thereby preventing a large amount of tobacco shreds and ash residue from adhering to the nozzle assembly 130 and the inner wall of the roller 200, and improving the utilization rate of the tobacco material. The specific structure of the nozzle adjusting device 100 in some embodiments is described below.

[0061] See Figures 1 to 3 In one embodiment, the nozzle adjusting device 100 includes a first support frame 110, a second support frame 120, a nozzle assembly 130, and a locking assembly 140. The first support frame 110 is radially disposed within the roller 200 and is movable axially along the roller 200. The second support frame 120 is disposed on the first support frame 110 and extends radially along the roller 200. The nozzle assembly 130 is disposed on the second support frame 120. The locking assembly 140 connects the first support frame 110 and the second support frame 120. The locking assembly 140 allows the second support frame 120 to move along the first support frame 110, and the second support frame 120 to move along the locking assembly 140. The locking assembly 140 can lock and fix the first support frame 110 and the second support frame 120. Figure 3 for Figure 1The diagram shows the connection of the first support frame 110, the second support frame 120, and the locking assembly 140 in the nozzle adjustment device 100.

[0062] The first support frame 110 is radially disposed on the inner wall of the roller 200. Further, the first support frame 110 is radially disposed on the inner wall of the inner cylinder 210, so that the first support frame 110 extends horizontally (laterally). Moreover, the first support frame 110 can also move axially (front-back direction) along the roller 200 to adjust the position of the nozzle adjusting device 100 within the roller 200. The second support frame 120 also extends radially (further as...). Figure 1 and Figure 2 (as shown in the longitudinal direction), and is disposed on the first support frame 110, and the second support frame 120 is perpendicular to the axial direction of the first support frame 110 and the roller 200.

[0063] The nozzle assembly 130 is the main component of the nozzle adjustment device 100 for spraying operations. The nozzle assembly 130 is mounted on the second support frame 120, which supports the nozzle assembly 130. The locking assembly 140 connects the first support frame 110 and the second support frame 120, locking the two frames to fix the position of the second support frame 120 relative to the first support frame 110, thereby fixing the position of the nozzle assembly 130.

[0064] When the locking assembly 140 is unlocked, it can move the second support frame 120 and the nozzle assembly 130 along the first support frame 110. The second support frame 120 can also move the nozzle assembly 130 relative to the locking assembly 140. After the nozzle assembly 130 is adjusted, the locking assembly 140 locks the first support frame 110 and the second support frame 120. At the same time, the first support frame 110 can also move the locking assembly 140, the second support frame 120 and the nozzle assembly 130 along the axial direction of the roller 200 to realize the adjustment of the overall position of the nozzle adjusting device 100 along the axial direction of the roller 200.

[0065] Thus, the position of the nozzle assembly 130 in the horizontal and vertical directions can be adjusted by adjusting the locking component 140 in the horizontal and vertical directions, thereby adjusting the spray direction and angle of the nozzle assembly 130. At the same time, the nozzle adjustment device 100 can be moved as a whole in the front and back directions as needed to adjust the nozzle assembly 130 in the X-axis, Y-axis and Z-axis directions, thereby meeting the needs of the nozzle assembly 130 for spraying in different directions.

[0066] This application uses a first support frame 110, a second support frame 120, and a locking assembly 140 to support the nozzle assembly 130 on the inner wall of the roller 200. This eliminates the need for a spray plate in the roller 200, reducing the area of ​​the nozzle assembly 130 and thus reducing the amount of tobacco material adhering to it. At the same time, water is not sprayed onto the inner wall of the inner cylinder 210 and the inner wall of the outer cylinder 220. This greatly reduces the amount of tobacco material adhering to the inner wall of the inner cylinder 210 and the inner wall of the outer cylinder 220, minimizing the adhesion of tobacco material to the nozzle assembly 130 and the inner wall of the roller 200, and improving material utilization.

[0067] Furthermore, the nozzle assembly 130 of this application is positioned close to the inlet end 230, which minimizes the arrangement of the water supply pipeline of the nozzle assembly 130 in the roller 200, reduces the complexity of the water supply pipeline, and thus minimizes the possibility of dripping or seepage. This prevents the formation of wet clumps of tobacco, water-stained tobacco, and yellow-spotted tobacco in the tobacco rehydration machine 10 during the next production run, reducing potential safety and quality risks to the product.

[0068] The nozzle adjusting device 100 of the above embodiment can adjust the position of the nozzle assembly 130 in the roller 200 through the first support frame 110, the second support frame 120, and the locking component 140, and lock the first support frame 110 and the second support frame 120 through the locking component 140. In this way, the position of the nozzle assembly 130 in the roller 200 can be adjusted to meet the needs of water spraying in different directions, so as to ensure that the moisture content of the output tobacco material is uniform and consistent, improve the re-moistening effect of the tobacco material, and ensure the quality stability of the cigarette product. At the same time, the nozzle adjusting device 100 uses the nozzle assembly 130 for spraying operation, eliminating the need for a spray plate, reducing the area of ​​the nozzle assembly 130, and thus avoiding a large amount of tobacco shreds and ash residue adhering to the nozzle assembly 130 and the inner wall of the roller 200, thereby improving the utilization rate of the tobacco material.

[0069] See Figures 1 to 4 In one embodiment, the first support frame 110 includes a first support rod 111 and two first support plates 112. The first support rod 111 extends radially along the roller 200, and the two first support plates 112 are respectively disposed at both ends of the first support rod 111. A locking assembly 140 is connected to the first support rod 111, and the two first support plates 112 conform to the inner wall of the roller 200 and are capable of moving axially along the roller 200. Figure 4 for Figure 1 A schematic diagram of the first support frame 110 in the nozzle adjusting device 100 shown.

[0070] The first support rod 111 is the main body rod of the first support frame 110. The first support rod 111 extends laterally, and two first support plates 112 are disposed at both ends of the first support rod 111. The first support rod 111 is movably disposed on the inner wall of the roller 200 in the front-back direction, and is supported to the inner wall of the roller 200 by the first support plates 112. The locking assembly 140 is disposed on the first support rod 111 and can move along the first support rod 111.

[0071] In this way, the nozzle adjusting device 100 can move along the axial direction of the roller 200 via the first support plate 112, thereby adjusting the position of the entire nozzle adjusting device 100 in the front-back direction. When the locking assembly 140 is unlocked, the locking assembly 140 can move along the first support rod 111 to adjust the lateral position of the nozzle assembly 130.

[0072] Optionally, the first support rod 111 and the first support plate 112 are an integral structure to ensure the structural strength of the first support frame 110. Of course, in other embodiments of this application, the first support rod 111 and the first support plate 112 can also be set separately and reliably connected by welding, threaded connection or other means.

[0073] See Figures 1 to 4 In one embodiment, the first support plate 112 has an adjusting groove 1121 that extends along the axial direction of the roller 200. Fasteners are installed on the inner wall of the roller 200 through the adjusting groove 1121. The first support plate 112 can move along the fasteners through the adjusting groove 1121.

[0074] The adjusting groove 1121 is disposed through the first support rod 111 and extends in the front-back direction. After the first support plate 112 is installed on the inner wall of the roller 200 by fasteners, the first support rod 111 can move along the fasteners through the adjusting groove 1121 to adjust the position of the first support plate 112 and the first support rod 111 in the front-back direction, thereby adjusting the position of the nozzle adjusting device 100 in the front-back direction.

[0075] Optionally, the adjusting groove 1121 is an oblong hole or a strip-shaped hole. Optionally, there are two adjusting grooves 1121, which are respectively disposed on the upper and lower sides of the connection between the first support rod 111 and the first support plate 112. This ensures the stability of the first support frame 110 moving in the front-back direction. Of course, in other embodiments of this application, the number of adjusting grooves 1121 may be one or more.

[0076] See Figures 1 to 4In one embodiment, the first support plate 112 is arc-shaped and can fit against the inner wall of the roller 200. That is, the first support plate 112 is an arc-shaped plate. The arc-shaped first support plate 112 can easily fit against the inner wall of the roller 200, improving the stability of the installation of the first support plate 112.

[0077] See Figures 1 to 4 In one embodiment, the outer peripheral surface of the first support rod 111 has a first scale value 1111, which indicates the moving distance of the locking assembly 140 along the first support rod 111. The first scale value 1111 extends laterally and is disposed on the outer wall of the first support rod 111. When the locking assembly 140 drives the second support frame 120 and the nozzle assembly 130 to move along the first support rod 111, the first scale value 1111 can indicate the lateral moving distance of the locking assembly 140, thereby achieving accurate adjustment of the position of the nozzle assembly 130.

[0078] See Figures 1 to 5 In one embodiment, the second support frame 120 includes a second support rod 121 and a second support plate 122. The second support plate 122 is disposed at one end of the second support rod 121 and is used to mount the nozzle assembly 130. The second support rod 121 is disposed on the locking assembly 140 and is movable along the locking assembly 140. Figure 5 for Figure 1 A schematic diagram of the second support frame 120 in the nozzle adjusting device 100 shown.

[0079] The second support rod 121 is the main rod of the second support frame 120. The second support rod 121 extends generally longitudinally and is disposed in the locking assembly 140. The second support plate 122 is disposed on the second support rod 121 and is used to support the installation of the nozzle assembly 130. When the locking assembly 140 is unlocked, the second support rod 121 can drive the nozzle assembly 130 to move approximately longitudinally via the second support plate 122, so as to adjust the longitudinal position of the nozzle assembly 130.

[0080] In this embodiment, the second support plate 122 is disposed on the top of the second support rod 121. Thus, the nozzle assembly 130 is disposed on the top of the second support rod 121. Of course, in other embodiments of this application, the second support plate 122 may also be disposed on the side of the second support rod 121.

[0081] Optionally, the second support rod 121 and the second support plate 122 are an integral structure to ensure the structural strength of the second support frame 120. Of course, in other embodiments of this application, the second support rod 121 and the second support plate 122 can also be separately arranged and reliably connected by welding, threaded connection or other methods.

[0082] See Figures 1 to 5In one embodiment, the second support rod 121 is arranged perpendicularly to the first support rod 111. That is, the second support rod 121 extends longitudinally. In this way, the second support rod 121 can drive the second support plate 122 and the nozzle assembly 130 to move longitudinally, thereby adjusting the position of the nozzle assembly 130. Of course, in other embodiments of this application, the second support rod 121 may also be arranged obliquely relative to the first support rod 111, so that the second support rod 121 extends substantially longitudinally.

[0083] See Figures 1 to 5 In one embodiment, the outer peripheral surface of the second support rod 121 has a second scale value 1211, which indicates the distance the second support rod 121 moves along the locking assembly 140. The second scale value 1211 extends longitudinally and is disposed on the outer wall of the second support rod 121. When the second support rod 121 moves relative to the locking assembly 140, the distance the second support rod 121 moves longitudinally can be indicated by the second scale value 1211, thereby achieving accurate adjustment of the position of the nozzle assembly 130.

[0084] See Figures 1 to 5 In one embodiment, the second support plate 122 has a fixing hole 1221, and the nozzle assembly 130 includes a nozzle body 131 and a locking member 132. The nozzle body 131 is installed in the fixing hole 1221, and the locking member 132 locks the nozzle body 131 to the second support plate 122. The fixing hole 1221 is provided through the second support plate 122, and the nozzle body 131 is installed through the fixing hole 1221. The locking member 132 can reliably lock the nozzle body 131 to the second support plate 122.

[0085] In this way, the nozzle body 131 can be reliably fixed to the second support plate 122 by the locking member 132, which prevents the position of the nozzle body 131 relative to the second support plate 122 from shifting, thus playing a role in preventing loosening and achieving reliable fixing of the nozzle body 131, thereby ensuring that the nozzle body 131 can accurately spray tobacco materials.

[0086] Optionally, there are two locking elements 132, which can be locked to the nozzle body 131 respectively. Loosening is prevented by tightening the double locking elements 132 to generate axial pressure and increase the frictional resistance of the threaded parts. Optionally, the locking element 132 is a lock nut.

[0087] In this embodiment, the nozzle body 131 is a dual-medium nozzle. The second support plate 122 is installed on the shoulder of the dual-medium nozzle and locked in place by locking nuts, with loosening prevented by tightening the double locking nuts. The dual-medium nozzle has good sealing performance, which can prevent leakage and seepage.

[0088] Of course, in other embodiments of this application, the nozzle body 131 may also be other types of nozzles, such as atomizing nozzles or mixing nozzles, etc. In this case, the size of the fixing hole 1221 can be adjusted to install different types of nozzle bodies 131.

[0089] See Figures 1 to 6 In one embodiment, the locking assembly 140 includes a first locking member 141 and a second locking member 142. The first locking member 141 is disposed on the second locking member 142. The first locking member 141 is movably disposed on the first support rod 111 and can be locked to the first support rod 111. The second locking member 142 is movably disposed on the second support rod 121 and can be locked to the second support rod 121. Figure 6 for Figure 1 A schematic diagram of the locking assembly 140 in the nozzle adjusting device 100 shown.

[0090] The first locking member 141 and the second locking member 142 are vertically connected. The first locking member 141 is used to connect the first support rod 111, and the second locking member 142 is used to connect the second support rod 121. When the first locking member 141 is unlocked, it can drive the second locking member 142 and the second support frame 120 to move along the first support rod 111 to adjust the position of the nozzle assembly 130 in the lateral direction. When the second locking member 142 is unlocked, the second support rod 121 can move along the second locking member 142 to adjust the position of the nozzle assembly 130 in the longitudinal direction.

[0091] Furthermore, after the nozzle assembly 130 is positioned, the first locking member 141 is locked to the first support rod 111, and the second locking member 142 is locked to the second support rod 121, to prevent the locking assembly 140 and the second support rod 121 from shifting position, thus ensuring reliable fixation of the nozzle assembly 130. Optionally, the first locking member 141 and the second locking member 142 can be reliably fixed by means of threaded parts, welding, adhesive bonding, etc.

[0092] See Figures 1 to 6 In one embodiment, the first locking member 141 includes a first locking block 1411 and a first adjusting member 1412. The first locking block 1411 has a first mounting hole 14111. The first locking block 1411 is sleeved on the first support rod 111 through the first mounting hole 14111 and can move along the first support rod 111. The first adjusting member 1412 is connected to the first locking block 1411 to adjust the inner diameter of the first mounting hole 14111, so that the first locking block 1411 is locked or unlocked to the first support rod 111.

[0093] The first locking block 1411 has a clamp-like structure and is connected to the second locking member 142. The first locking block 1411 has a through first mounting hole 14111 through which a first support rod 111 can pass. A first adjusting member 1412 is disposed on the first locking block 1411 and is a component for locking or unlocking the first locking block 1411.

[0094] When the first adjusting member 1412 unlocks the first locking block 1411, the first locking block 1411 can move along the first support rod 111 through the first mounting hole 14111. Subsequently, the first locking block 1411 can drive the second support frame 120 and the nozzle assembly 130 to move laterally via the second locking member 142. After the nozzle assembly 130 has been laterally adjusted, the first adjusting member 1412 can lock the first locking block 1411, so that the first locking block 1411 is securely connected to the first support rod 111.

[0095] See Figures 1 to 6 In one embodiment, the first adjusting member 1412 is an adjusting bolt, and the first locking block 1411 has a first threaded hole communicating with the first mounting hole 14111. The adjusting bolt is installed in the first threaded hole and can adjust the inner diameter of the first mounting hole 14111.

[0096] After the adjusting bolt is installed in the first threaded hole, tightening the adjusting bolt reduces the inner diameter of the first mounting hole 14111, causing the inner wall of the first mounting hole 14111 to grip the outer wall of the first support rod 111, thus locking the first locking block 1411 to the first support rod 111. Loosening the adjusting bolt increases the inner diameter of the first mounting hole 14111, allowing the first locking block 1411 to move along the first support rod 111 through the first mounting hole 14111.

[0097] Of course, in other embodiments of this application, the first adjusting member 1412 is an adjusting clamp, which is sleeved on the first locking block 1411. When the adjusting clamp is tightened, it can reduce the inner diameter of the first mounting hole 14111; when the adjusting clamp is loosened, it can increase the inner diameter of the first mounting hole 14111.

[0098] See Figures 1 to 6 In one embodiment, the second locking member 142 includes a second locking block 1421 and a second adjusting member 1422. The second locking block 1421 has a second mounting hole 14211. The second locking block 1421 is sleeved on the second support rod 121 through the second mounting hole 14211 and can move along the second support rod 121. The second adjusting member 1422 is connected to the second locking block 1421 to adjust the inner diameter of the second mounting hole 14211, so that the second locking block 1421 is locked or unlocked to the second support rod 121.

[0099] The second locking block 1421 has a clamp-like structure and is connected to the first locking block 1411. The second locking block 1421 has a through-hole 14211 through which the second support rod 121 can pass. The second adjusting member 1422 is disposed on the second locking block 1421 and is a component for locking or unlocking the second locking block 1421.

[0100] When the second adjusting member 1422 unlocks the second locking block 1421, the second support rod 121 can move relative to the second locking block 1421 along the second mounting hole 14211, thereby driving the second support plate 122 and the nozzle assembly 130 to move longitudinally. After the nozzle assembly 130 has been adjusted laterally, the second adjusting member 1422 can lock the second locking block 1421 so that the second locking block 1421 is locked to the second support rod 121.

[0101] See Figures 1 to 6 In one embodiment, the second adjusting member 1422 is an adjusting bolt, and the second locking block 1421 has a second threaded hole that communicates with the second mounting hole 14211. The adjusting bolt is installed in the second threaded hole and can adjust the inner diameter of the second mounting hole 14211. Alternatively, the second adjusting member 1422 is an adjusting clamp, and the adjusting clamp is sleeved on the second locking block 1421.

[0102] After the adjusting bolt is installed in the second threaded hole, tightening the adjusting bolt reduces the inner diameter of the second mounting hole 14211, causing the inner wall of the second mounting hole 14211 to grip the outer wall of the second support rod 121, thus locking the second locking block 1421 to the second support rod 121. Loosening the adjusting bolt increases the inner diameter of the second mounting hole 14211, allowing the second support rod 121 to move relative to the second locking block 1421 along the second mounting hole 14211.

[0103] Of course, in other embodiments of this application, the second adjusting member 1422 is an adjusting clamp, which is sleeved on the second locking block 1421. When the adjusting clamp is tightened, it can reduce the inner diameter of the second mounting hole 14211; when the adjusting clamp is loosened, it can increase the inner diameter of the second mounting hole 14211.

[0104] The nozzle adjustment device 100 of this application can adjust the position of the nozzle assembly 130 in the drum 200 through the first support frame 110, the second support frame 120, and the locking assembly 140, and lock the first support frame 110 and the second support frame 120 through the locking assembly 140. In this way, the position of the nozzle assembly 130 in the drum 200 can be adjusted to meet the needs of water spraying in different directions, so as to ensure that the moisture content of the output tobacco material is uniform, improve the re-moistening effect of the tobacco material, and ensure the quality stability of the cigarette product.

[0105] Meanwhile, the nozzle adjustment device 100 uses the nozzle assembly 130 for spraying, eliminating the need for a spray plate and reducing the area of ​​the nozzle assembly 130. This prevents a large amount of tobacco shreds and ash residue from adhering to the nozzle assembly 130 and the inner wall of the roller 200, improving the utilization rate of tobacco materials. Furthermore, the nozzle assembly 130 is positioned close to the inlet end 230, reducing the need for water pipes in the roller 200. Combined with the dual-medium nozzle spraying operation, this minimizes the risk of dripping and seepage, thus preventing wet clumps of tobacco, water-stained tobacco, and yellow-spotted tobacco from appearing in the tobacco rehydration machine 10 during the next production run, reducing potential product safety and quality hazards.

[0106] 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.

[0107] 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.
