Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a condensate drip prevention mechanism. Background Technology

[0002] A tobacco sheet re-drying machine typically includes a drying zone, a cooling zone, and a rehumidification zone. During the processing of tobacco sheet materials using this machine, after drying and cooling, the materials enter the rehumidification zone for rehumidification to ensure that the material meets the moisture content and temperature requirements for subsequent production. The rehumidification zone works by using a mixture of steam and water, high-pressure atomized water, and steam under the action of a circulating fan to achieve rehumidification of the tobacco sheet materials through forced convection within the rehumidification chamber. Therefore, the rehumidification chamber maintains a high-temperature and high-humidity environment throughout the process. Consequently, condensation droplets form on the top plate of the rehumidification chamber. If too many condensation droplets accumulate on the top plate, they may drip into the tobacco sheet material below. If this condensation drips into the tobacco sheet material, it will not only cause deviations from the predetermined rehumidification parameters but also result in wet clumps and water stains, affecting the processing quality of the tobacco sheet material. To reduce the probability of the above-mentioned situation, existing technologies typically install a steam coil at the top of the rehumidification chamber in a tobacco re-drying machine. During the rehumidification process, the condensation droplets on the top plate of the rehumidification chamber are eliminated by heating the steam coil. However, the complex structure of the steam coil leads to high production costs, and the need to heat the steam coil results in high energy consumption during use, leading to high operating costs. Furthermore, the temperature of the steam coil may affect the temperature regulation and control within the rehumidification chamber during the heating process. Utility Model Content

[0003] The purpose of this utility model is to provide a condensate drip prevention mechanism that can prevent condensate dripping from the top into the tobacco sheet material below, thereby reducing production and usage costs, while not affecting the temperature regulation and control process inside the rehumidification chamber.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A condensate drip prevention mechanism, located at the top of the rehumidification chamber in the tobacco sheet re-drying machine, includes:

[0006] A water-guiding top plate is disposed inside the rehumidification box and located at the top of the rehumidification box, and at least part of the water-guiding top plate is inclined along the height direction of the rehumidification box;

[0007] The water collection tank is connected to the moisture recovery box at the lowest point of the top water guide plate, and the condensate that condenses on the lower end face of the top water guide plate can flow along the top water guide plate to the water collection tank.

[0008] As a further technical solution, the water guiding top plate is inclined towards the horizontal plane along the left-to-right direction, the water collection trough is fixedly installed on the right side wall of the rehumidification box, and the projection of the water guiding top plate on the bottom wall of the rehumidification box covers the bottom wall of the rehumidification box.

[0009] As a further technical solution, 3°≤α≤15°, where α is the tilt angle of the water guide plate.

[0010] As a further technical solution, the condensate anti-drip mechanism also includes a hydrophilic component, which is laid on the lower end surface of the water-guiding top plate.

[0011] As a further technical solution, the condensate anti-drip mechanism also includes an adjusting connection component and a rotating connection component. The left side of the water guide top plate is adjustablely connected to the left side wall of the rehumidification box via the adjusting connection component, and the right side of the water guide top plate is rotatably connected to the right side wall of the rehumidification box via the rotating connection component. Adjusting the adjusting connection component allows the water guide top plate to rotate around the rotating connection component, thereby changing the tilt angle of the water guide top plate.

[0012] As a further technical solution, the adjusting connection assembly includes a connector and two screws. The two screws are respectively disposed opposite to each other on the left side of the water guide top plate and the top plate of the rehumidification box, and are respectively threadedly connected to the connector.

[0013] Alternatively, the adjusting connection assembly includes a telescopic rod, with both ends of the telescopic rod connected to the left side of the water guide top plate and the top plate of the rehumidification box, respectively.

[0014] Alternatively, the adjusting connection assembly includes a push rod motor, which is disposed on the top plate of the rehumidification box, and the output shaft of the push rod motor extends along the height direction and is drively connected to the left side of the water guide top plate.

[0015] As a further technical solution, the rotating connection assembly includes a connecting shaft and a connecting reinforcement. The connecting reinforcement is fixedly disposed on the right side wall of the rehumidification box and extends along the width direction of the right side wall of the rehumidification box. The right side of the water guide top plate is rotatably connected to the connecting reinforcement through the connecting shaft.

[0016] As a further technical solution, the condensate anti-drip mechanism also includes a flexible auxiliary component, which is disposed on the left side wall of the water guide top plate. When the tilt angle of the water guide top plate is adjusted, the flexible auxiliary component can always abut against the left side wall of the rehumidification box.

[0017] As a further technical solution, a baffle plate is provided at the open end of the water collection tank. The baffle plate is located on the left side wall of the water collection tank and extends towards the right side wall of the water collection tank. The width of the baffle plate is smaller than the width of the water collection tank.

[0018] And / or, a water guide is provided on the right side of the water guide top plate, and the water guide extends along the height direction of the rehumidification box into the water collection tank.

[0019] As a further technical solution, the condensate anti-drip mechanism also includes a heat insulation component, which is disposed inside the rehumidification box and on the side of the water guide plate away from the water collection tank.

[0020] Compared with the prior art, the condensate anti-drip mechanism provided by this utility model has the following technical advantages:

[0021] Because the top water guide plate is inclined along the height of the rehumidification box, and the water collection trough is located corresponding to the lowest point of the top water guide plate, during the rehumidification process of the tobacco sheet material in the rehumidification box, when condensate droplets accumulate on the top water guide plate, due to the inclined design of the top water guide plate, the condensate droplets will flow along the lower end face of the top water guide plate to the lowest point of the top water guide plate under the action of gravity, and finally flow into the water collection trough located at the lowest point of the top water guide plate. Throughout the process, firstly, the inclined top plate and the water collection trough work together to guide and collect condensate droplets, preventing the condensate droplets from falling onto the tobacco sheet material below, thus ensuring the rehumidification effect of the tobacco sheet material in the rehumidification chamber. Secondly, the entire structure consists only of the top plate and the water collection trough, making it relatively simple and reducing production costs. Finally, during the use of the condensate anti-drip mechanism, there is no need to heat the top plate or the water collection trough, thereby reducing energy consumption, saving operating costs, and preventing the condensate anti-drip mechanism from affecting the temperature regulation and control process inside the rehumidification chamber, further ensuring the rehumidification effect of the tobacco sheet material.

[0034] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0035] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0036] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0037] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0038] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0039] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0040] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element.

For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0041] Specific combination Figure 1As shown, the condensate drip prevention mechanism provided in this embodiment is installed at the top of the rehumidification chamber 10 in the tobacco sheet re-drying machine to prevent condensate from dripping into the tobacco sheet material placed in the rehumidification chamber 10. This condensate drip prevention mechanism can prevent condensate from dripping from the top into the tobacco sheet material below, thereby reducing production and usage costs, and will not affect the temperature regulation and control process inside the rehumidification chamber 10. Specifically, the condensate drip prevention mechanism includes a water guide plate 100 and a water collection tank 200: the water guide plate 100 is installed inside the rehumidification chamber 10 and located at the top of the rehumidification chamber 10, and at least part of the water guide plate 100 is inclined along the height direction of the rehumidification chamber 10; the water collection tank 200 is connected to the rehumidification chamber 10 at the lowest point corresponding to the water guide plate 100, and the condensate condensed on the lower end surface of the water guide plate 100 can flow along the water guide plate 100 to the water collection tank 200.

[0042] Since the top water guide plate 100 is inclined along the height direction of the rehumidification chamber 10 and the water collection trough 200 is correspondingly located at the lowest point of the top water guide plate 100 within the rehumidification chamber 10, during the rehumidification process of the tobacco sheet material in the rehumidification chamber 10, when condensate droplets accumulate on the top water guide plate 100, due to the inclined arrangement of the top water guide plate 100, the condensate droplets will flow along the lower end face of the top water guide plate 100 to the lowest point of the top water guide plate 100 under the action of gravity, and finally flow into the water collection trough 200 located at the lowest point of the top water guide plate 100. Therefore, after the condensate anti-drip mechanism provided in this embodiment is installed in the rehumidification chamber 10, it is not necessary to install a steam coil in the rehumidification chamber 10, thus achieving the technical effect of preventing condensate droplets from the top from falling into the tobacco sheet material below. In the use of the condensate drip prevention mechanism provided in this embodiment, firstly, the inclined water guide plate 100 cooperates with the water collection tank 200 to guide and collect condensate droplets, preventing condensate droplets condensed on the water guide plate 100 from falling into the tobacco sheet material below, thereby ensuring the rehumidification effect of the tobacco sheet material in the rehumidification box 10; secondly, the entire structure consists only of the water guide plate 100 and the water collection tank 200, which is relatively simple and can reduce production costs; finally, during the use of the condensate drip prevention mechanism, there is no need to heat the water guide plate 100 or the water collection tank 200, thereby reducing energy consumption, saving operating costs, and preventing the condensate drip prevention mechanism from affecting the temperature regulation and control process in the rehumidification box 10, so as to further ensure the rehumidification effect of the tobacco sheet material.

[0043] In addition, since the condensate anti-drip mechanism consists of only a water guide plate 100 and a water collection tank 200, its structure is relatively simple. Therefore, it can be installed on tobacco sheet re-drying machines of different specifications according to actual needs, thereby expanding its applicability.

[0044] Depending on the actual situation of the recirculation chamber 10, the water guide plate 100 can be configured in various forms. Taking a rectangular cross-sectional shape along the height direction of the recirculation chamber 10 as an example, the forms of the water guide plate 100 include, but are not limited to: a flat or curved plate with one side higher than the other side along the height direction; an irregularly shaped plate with any two sides higher than the other two sides along the height direction; an irregularly shaped plate with any three sides higher than the other side along the height direction; or a conical or spherical dome with a high center and two or three sides lower than the edges, or all four sides lower than the other side along the height direction. To prevent condensate from accumulating on the top wall of the rehumidification chamber 10 and dripping directly onto the tobacco sheet material below, the projection of any type of water-guiding top plate 100 onto the bottom wall of the rehumidification chamber 10 must cover the bottom wall of the rehumidification chamber 10. This prevents steam from condensing on the top wall of the rehumidification chamber 10. Furthermore, when the volume of the rehumidification chamber 10 is too large, to reduce complexity, multiple water-guiding top plates 100 are installed on the top of the rehumidification chamber 10. These multiple water-guiding top plates 100 are spliced ​​together so that their projections onto the bottom wall of the rehumidification chamber 10 all cover the bottom wall of the rehumidification chamber 10. Figure 2 As shown.

[0045] For ease of explanation, in this embodiment, the water guiding top plate 100 is set as a flat plate. Specifically, along the direction from left to right, the water guiding top plate 100 is inclined towards the horizontal plane, and the water collection trough 200 is fixedly set on the right side wall of the rehumidification box 10. This ensures the water guiding effect of the water guiding top plate 100 while reducing the installation difficulty of the water guiding top plate 100 when installed in the rehumidification box 10.

[0046] In other embodiments, depending on the actual setup of the rehumidification chamber 10, the top water guide plate 100 can be adaptively tilted in any direction toward the horizontal plane, as long as the top water guide plate 100 has a highest and lowest point within the rehumidification chamber 10, the water collection trough 200 is connected to the rehumidification chamber 10 at the lowest point of the top water guide plate 100, and the condensed water droplets condensed on the lower end face of the top water guide plate 100 can be guided into the water collection trough 200, and the technical effect of preventing the top condensed water droplets from falling into the tobacco sheet material below can be achieved.

[0047] Furthermore, 3°≤α≤15°, where α is the tilt angle of the top water guide plate 100. If the tilt angle of the top water guide plate 100 is too large or too small, the drainage effect of the top water guide plate 100 on the condensate droplets collected on its lower end face cannot be guaranteed. If the tilt angle of the top water guide plate is less than 3°, the condensate droplets collected on the lower end face of the top water guide plate 100 may drip directly from the top water guide plate 100 into the tobacco sheet material below; if the tilt angle of the top water guide plate is greater than 15°, the condensate droplets may drip into the tobacco sheet material below while flowing along the top water guide plate 100. In this embodiment, the tilt angle of the top water guide plate 100 can be adaptively set to 4°, 8°, 13°, etc., according to the steam content in the rehumidification box 10 during the rehumidification process; no specific limitation is made here.

[0048] Furthermore, the condensate anti-drip mechanism also includes a hydrophilic component 300, which is laid on the lower end surface of the water guide plate 100.

[0049] Specifically, a hydrophilic coating is applied to the lower end surface of the top water-guiding plate 100 to form a hydrophilic component 300, which covers the entire lower end surface of the top water-guiding plate 100. Thus, during the rehumidification process, the hydrophilic component 300 increases the adhesion of condensate droplets to the top water-guiding plate 100, thereby further improving the effect of guiding the condensate droplets to the water collection tank 200, and further preventing condensate droplets condensed on the top water-guiding plate 100 from falling into the tobacco sheet material below. The thickness of the hydrophilic coating applied to the lower end surface of the top water-guiding plate 100 and the type of hydrophilic coating can be adaptively set according to the steam content in the rehumidification chamber 10 during the rehumidification process. Furthermore, the hydrophilic coating is not the focus of this solution; its principle is based on existing technology and will not be elaborated here.

[0050] Preferably, the condensate drip prevention mechanism further includes an adjusting connection assembly 400 and a rotating connection assembly 500. The left side of the water guide plate 100 is adjustablely connected to the left side wall of the rehumidification chamber 10 via the adjusting connection assembly 400, and the right side of the water guide plate 100 is rotatably connected to the right side wall of the rehumidification chamber 10 via the rotating connection assembly 500. Adjusting the adjusting connection assembly 400 allows the water guide plate 100 to rotate around the rotating connection assembly 500, thereby changing the tilt angle of the water guide plate 100. Thus, during the rehumidification process, the adjusting connection assembly 400 can be adaptively adjusted according to the steam content in the rehumidification chamber 10 to change the tilt angle of the water guide plate 100, further improving the guiding effect on condensate droplets and preventing condensate droplets from the water guide plate 100 from falling into the tobacco sheet material below. For example, during the rehumidification process, when the steam content in the rehumidification chamber 10 is low, the tilt angle of the water guide plate 100 is set to 4° or 6°, and when the steam content in the rehumidification chamber 10 is high, the tilt angle of the water guide plate 100 is set to 12° or 14°; the tilt angle of the water guide plate 100 is adjusted according to the period, and is not limited to the above situations.

[0051] Preferably, the adjusting connection assembly 400 includes a connector 410 and two screws 420. The two screws 420 are respectively disposed opposite to each other on the left side of the water guide plate 100 and the top plate of the moisture return box 10, and are threadedly connected to the connector 410. Thus, by turning one of the screws 420, the tilt angle of the water guide plate 100 can be adjusted by changing the relative position between the screw 420 and the connector 410; or, to improve the adjustment efficiency, both screws 420 can be turned simultaneously. To prevent condensate droplets from accumulating between the water guide plate 100 and the corresponding screw 420, in this embodiment, two sealing rings (not shown in the figure) are provided. Both sealing rings are fitted onto the corresponding screws 420 and are located on both sides of the water guide plate 100.

[0052] In some other embodiments, the adjusting connection assembly 400 includes a telescopic rod (not shown in the figure), with its two ends connected to the left side of the water guide top plate 100 and the top plate of the rehumidification box 10, respectively. The tilt angle of the water guide top plate 100 is adjusted by adjusting the telescopic rod's extension and retraction. To prevent the telescopic rod from extending on its own after adjustment, causing condensate droplets on the water guide top plate 100 to fall into the tobacco material below, a limiter is provided in the extension and retraction area of ​​the telescopic rod to limit the extension and retraction of the telescopic rod after the tilt angle of the water guide top plate 100 is adjusted.

[0053] In some other embodiments, the adjusting connection assembly 400 includes a push rod motor (not shown in the figure), which is disposed on the top plate of the rehumidification chamber 10. The output shaft of the push rod motor extends along the height direction and is connected to the left side of the water guide top plate 100. Thus, by controlling the extension and retraction of the push rod motor output shaft, the tilt angle of the water guide top plate 100 can be autonomously adjusted, ensuring adjustment accuracy while reducing adjustment difficulty. The specific structure and working principle of the push rod motor are described in the prior art and will not be repeated here.

[0054] Preferably, the rotating connection assembly 500 includes a connecting shaft 510 and a connecting reinforcement 520. The connecting reinforcement 520 is fixedly disposed on the right side wall of the rehumidification chamber 10 and extends along the width direction of the right side wall of the rehumidification chamber 10. The right side of the water guide plate 100 is rotatably connected to the connecting reinforcement 520 via the connecting shaft 510. Thus, by providing the connecting reinforcement 520, the connection strength and stability between the water guide plate 100 and the rehumidification chamber 10 are improved, ensuring the effectiveness of the water guide plate 100. Simultaneously, it prevents gaps from appearing between the right side of the water guide plate 100 and the right side wall of the rehumidification chamber 10, which would cause condensate droplets guided to the lowest point of the water guide plate 100 to drip into the tobacco material below. By providing the connecting shaft 510, the water guide plate 100 can rotate relative to the right side wall of the rehumidification chamber 10, thereby ensuring the ease of adjustment of the water guide plate 100. In some other embodiments, the right side of the water guide plate 100 can be directly rotatably connected to the right side wall of the rehumidification box 10 via a hinge structure.

[0055] Preferably, the condensate anti-drip mechanism further includes a flexible auxiliary component 600, which is disposed on the left side wall of the water guide plate 100. When adjusting the tilt angle of the water guide plate 100, the flexible auxiliary component 600 can always abut against the left side wall of the rehumidification box 10. During the adjustment of the tilt angle of the top water guide plate 100, when the tilt angle is adjusted from 3° to 15°, a gap appears between the left side of the top water guide plate 100 and the left side wall of the rehumidification chamber 10. This could cause condensate to collect directly from this gap on the top wall of the rehumidification chamber 10 and drip directly from the top wall of the rehumidification chamber 10 into the tobacco material below. To avoid this, a flexible auxiliary component 600 is provided on the left side wall of the top water guide plate 100. The flexible auxiliary component 600 extends along the width of the top water guide plate 100 and abuts against the left side wall of the rehumidification chamber 10 during the adjustment of the tilt angle, thus preventing the gap from appearing between the left side of the top water guide plate 100 and the left side wall of the rehumidification chamber 10. The flexible auxiliary component 600 can be made of silicone, rubber, plastic, etc., depending on the actual situation; no specific limitation is made here. The connection method of the flexible auxiliary component 600 to the left side wall of the water guide plate 100 can be selected according to the actual situation, such as bonding or integral molding.

[0056] Preferably, a baffle plate 210 is provided at the open end of the water collection tank 200. The baffle plate 210 is disposed on the left side wall of the water collection tank 200 and extends towards the right side wall of the water collection tank 200, and the width of the baffle plate 210 is smaller than the width of the water collection tank 200. In this way, the width of the open end of the water collection tank 200 is reduced, and the condensate collected in the water collection tank 200 is prevented from splashing into the tobacco material below as condensate drips from the right side of the water guide plate 100 into the water collection tank 200. In some other embodiments, the baffle plate 210 may be omitted, and the height of the left side wall of the water collection tank 200 may be set to be greater than the height of the right side wall of the water collection tank 200.

[0057] A water guide 110 is provided on the right side of the top water guide plate 100, extending along the height of the rehumidification box 10 into the water collection tank 200. When condensed water droplets on the lower end face of the top water guide plate 100 flow to the lowest point of the top water guide plate 100, i.e., when the condensed water droplets flow to the far right of the top water guide plate 100, the condensed water droplets can flow along the water guide 110 into the water collection tank 200, thus preventing the condensed water droplets from dripping directly from the far right of the top water guide plate 100 into the water collection tank 200, which would cause the condensed water collected in the water collection tank 200 to splash into the tobacco sheet material below. Along the width direction of the top water guide plate 100, multiple water guides 110 are provided at intervals on the right side of the top water guide plate 100. The water guides 110 can be directly made of wool, cotton thread, etc.

[0058] Preferably, the condensate anti-drip mechanism further includes a heat insulation component 700, which is disposed inside the rehumidification box 10 and on the side of the water guide top plate 100 away from the water collection tank 200.

[0059] Specific combination Figure 1 As shown, insulation material can be filled between the top plate of the water guide plate 100 and the top plate of the rehumidification chamber 10 to form an insulation component 700. Alternatively, the insulation component 700 can be directly placed on the top plate of the rehumidification chamber 10. Or, while filling the top plate of the water guide plate 100 and the top plate of the rehumidification chamber 10 with insulation material, the insulation component 700 can be placed on the top plate of the rehumidification chamber 10. By setting the insulation component 700, heat loss within the rehumidification chamber 10 is reduced, thereby ensuring the rehumidification effect of the tobacco sheet material within the rehumidification chamber 10. In this embodiment, the insulation component 700 is placed on the top plate of the rehumidification chamber 10, and the thickness of the insulation component 700 is set to 20mm to 100mm. This setting reduces heat loss within the rehumidification chamber 10 and avoids interference between the water guide plate 100 and the insulation component 700 during the adjustment of the tilt angle of the water guide plate 100. The specific material for the insulation component 700 can be selected according to actual needs; no specific limitations are made here.

[0060] In summary, the working principle of the condensate anti-drip mechanism provided in this embodiment is as follows: the water guide plate 100 is inclined towards the horizontal plane and installed on the top of the rehumidification box 10 from left to right. The left side of the water guide plate 100 is adjustablely connected to the left side wall of the rehumidification box 10 via the adjusting connecting assembly 400, and the right side of the water guide plate 100 is rotatably connected to the right side wall of the rehumidification box 10 via the rotating connecting assembly 500. The water collection tank 200 is fixedly installed on the right side wall of the rehumidification box 10, corresponding to the right side of the water guide plate 100. At the same time, a flexible auxiliary member 600 extending along the width direction of the water guide plate 100 is provided on the left side wall of the water guide plate 100, and multiple water guiding members 110 spaced apart along the width direction of the water guide plate 100 are provided on the right side of the water guide plate 100. Then, the adjusting connection component 400 is adjusted according to the steam content in the rehumidification chamber 10 to change the tilt angle of the water guide plate 100, ensuring that the water guide plate 100 can meet the current stage of condensate dripping requirements of the rehumidification chamber 10. In this state, the flexible auxiliary component 600 is always in contact with the left side wall of the rehumidification chamber 10. The water guide component 110 extends along the height direction of the rehumidification chamber 10 into the water collection tank 200. The rehumidification of the tobacco sheet material in the rehumidification chamber 10 begins. During the rehumidification process, some of the steam in the rehumidification chamber 10 condenses on the water guide plate 100 and forms condensate droplets. Under the action of gravity, the condensate droplets flow along the lower end face of the water guide plate 100 to the right side of the water guide plate 100, and then flow along the multiple water guide components 110 into the water collection tank 200. This prevents condensate from dripping onto the tobacco sheet material below, reducing production and operating costs, while also not affecting the temperature control process within the rehumidification chamber 10.

[0061] The condensate anti-drip mechanism provided in this embodiment is not limited to the rehumidification box 10. It can be applied to other high-temperature and high-humidity environments according to actual needs. No specific limitation is made here.
