Description

Technical Field

[0001] This invention relates to the field of tobacco processing equipment technology, and in particular to a tobacco pack rehumidification device and method. Background Technology

[0002] Rehumidification of tobacco packs is a crucial step in tobacco processing, preceding the loosening process. Its purpose is to increase the moisture content and temperature of the tobacco leaves on the pack surface, making the leaves softer and easier to loosen, improving their processing resistance, and reducing pack breakage during subsequent loosening processes. This plays a key role in ensuring processing quality and product yield. Currently, various rehumidification machine structures are widely used in tobacco processing for heating and humidifying tobacco leaves or packs, with the tunnel-type rehumidifier being the mainstream equipment for batch rehumidification of tobacco packs.

[0003] Existing conventional tunnel-type rehumidifiers typically use a steam supply component as the core unit for heating and humidifying. In terms of temperature and humidity detection and control architecture, they often only place a single-point temperature and humidity sensor at the equipment outlet, using the outlet's temperature and humidity readings as the control basis. The entire control process relies solely on adjusting the steam supply of the steam supply component to regulate the temperature and humidity parameters within the rehumidification chamber. This temperature and humidity control scheme has several drawbacks. Firstly, the single control point cannot comprehensively reflect the overall temperature and humidity state inside the rehumidification chamber, easily leading to poor rehumidification uniformity. This results in inconsistent rehumidification effects between different tobacco bales and even in different parts of the same bale, leading to poor product quality consistency within batches. Secondly, the limited means of temperature and humidity regulation, relying solely on the steam supply component, cannot achieve independent and precise temperature and humidity control, failing to meet the needs of refined rehumidification processes.

[0004] Therefore, there is an urgent need for a tobacco pack rehumidification device and method to solve the above-mentioned technical problems. Summary of the Invention

The electric baffle changes its tilt angle to reduce the air supply volume of the corresponding air outlet; the first preset temperature is lower than the second preset temperature; when the actual humidity is lower than the first preset humidity, the control component controls the atomizing humidification component and / or the steam supply component to increase the operating power, and simultaneously controls the electric baffle at the corresponding air outlet to change its tilt angle to increase the air supply volume of the corresponding air outlet; when the actual humidity is higher than the second preset humidity, the control component controls the atomizing humidification component and / or the steam supply component to decrease the operating power, and simultaneously controls the electric baffle at the corresponding air outlet to change its tilt angle to decrease the air supply volume of the corresponding air outlet; the first preset humidity is lower than the second preset humidity; in step S300, the rehydrated tobacco pack is transported to the outside of the rehydration box using the conveyor belt assembly.

[0016] In some embodiments, an intermediate preset humidity is provided between the first preset humidity and the second preset humidity; the difference between the intermediate preset humidity and the first preset humidity is equal to the difference between the second preset humidity and the intermediate preset humidity; when the actual humidity is lower than the intermediate preset humidity and the actual humidity shows a continuous decreasing trend, the control component controls the atomizing humidification component and / or the steam supply component to increase the operating power, and simultaneously controls the electric baffle at the corresponding air supply port to change the tilt angle, so as to increase the air supply volume of the corresponding air supply port; when the actual humidity is higher than the intermediate preset humidity and the actual humidity shows a continuous increasing trend, the control component controls the atomizing humidification component and / or the steam supply component to decrease the operating power, and simultaneously controls the electric baffle at the corresponding air supply port to change the tilt angle, so as to decrease the air supply volume of the corresponding air supply port.

[0017] The beneficial effects of this invention are:

[0018] On one hand, the present invention provides a tobacco pack rehumidification device. By setting up an air supply assembly capable of introducing circulating gas into the rehumidification chamber, the air supply assembly is structured to include multiple sets of air supply components arranged along the extension direction of the rehumidification chamber. Each air supply component includes air supply elements symmetrically arranged on opposite sides of the rehumidification chamber and connected to it. Each air supply element has two air inlets located on the upper and lower sides of a conveyor belt assembly, and an electric baffle is installed at each air inlet. Additionally, multiple sets of heating components and multiple sets of sensor components are provided, each corresponding to one of the multiple air supply elements. Multiple steam nozzles of a steam supply component are also provided, corresponding to one of the multiple air supply elements, and an atomizing humidification component is connected to the multiple air supply elements. This allows the tobacco packs to be transported into the rehumidification chamber using the conveyor belt assembly when rehumidification is required. Then, through the cooperation of the steam supply components and the air supply assembly, humid and hot circulating gas is generated inside the rehumidification chamber to rehumidify the tobacco packs. During the rehumidification process of tobacco packs using the aforementioned tobacco pack rehumidification device, multiple sensor components corresponding to multiple air supply components can detect the actual temperature and humidity at different locations inside the rehumidification chamber (i.e., the areas located on the upper and lower sides of the conveyor belt assembly, corresponding to the air supply components). The control component can then control the heating components, steam nozzles, and atomizing humidification components corresponding to different locations (or different air supply components) to operate independently based on these actual temperatures and humidity levels. This allows for precise detection and control of the actual temperature and humidity at different locations inside the rehumidification chamber, improving the uniformity of temperature and humidity throughout the chamber and thus enhancing the consistency of rehumidification effects for different tobacco packs and different parts (i.e., the upper and lower sides) of the same tobacco pack. Simultaneously, the aforementioned tobacco pack rehumidification equipment, through the coordination of the heating components, steam supply components, and atomizing humidification components, achieves temperature and humidity control within the rehumidification chamber. This enables independent and precise control of temperature and humidity during the rehumidification process, ensuring that both temperature and humidity meet the preset rehumidification requirements and guaranteeing the rehumidification effect.

[0019] On the other hand, the present invention provides a method for rehydrating tobacco packs, which includes the aforementioned tobacco pack rehydration device and has the same beneficial effects as the aforementioned tobacco pack rehydration device, so it will not be described again here.

[0031] Combination Figure 1 , Figure 2 As shown, this embodiment provides a tobacco pack rehumidification device. The tobacco pack rehumidification device includes a rehumidification chamber 1, a conveyor belt assembly 2, an air supply assembly, a heating assembly, a sensor assembly 5, a steam supply assembly, an atomizing humidification assembly 7, and a control assembly.

[0032] like Figure 1 As shown, the aforementioned rehumidification box 1 has a rectangular box structure, and the rehumidification box 1 extends along a first direction X1, where the first direction X1 is a horizontal direction. It is easy to understand that the aforementioned tobacco pack rehumidification equipment can also be equipped with a frame, which is, for example, a frame structure formed by a combination of multiple support rods and support plates, and the aforementioned rehumidification box 1 can be installed on the frame.

[0033] The aforementioned conveyor belt assembly 2 is installed inside the rehumidification box 1 along the first direction X1. This conveyor belt assembly 2 is used to convey cigarette packs. Specifically, the conveyor belt assembly 2 includes a support frame, multiple drive rollers, a drive unit, and a conveyor belt. The multiple drive rollers are rotatably mounted on the support frame and are spaced apart along the first direction X1. The drive unit is connected to one of the drive rollers. The conveyor belt is wound around the multiple drive rollers. The drive unit drives the drive rollers to rotate, which in turn moves the conveyor belt along the first direction X1, thereby conveying the cigarette packs along the first direction X1. It is easy to understand that the conveyor belt has multiple ventilation holes to facilitate the passage of rehumidification gas through it.

[0034] The aforementioned air supply assembly can introduce recirculated gas into the rehumidification chamber 1. Combined with... Figure 1 , Figure 2 As shown, the air supply assembly includes multiple sets of air supply components 31, which are evenly spaced along the first direction X1 and communicate with the rehumidification chamber 1. Each set of air supply components 31 includes two air supply elements 311 symmetrically arranged on opposite sides of the rehumidification chamber 1. Each air supply element 311 has two air inlets located on the upper and lower sides of the conveyor belt assembly 2, respectively, and an electric baffle is provided at the air inlet. It is easy to understand that the above-mentioned air supply assembly also includes other auxiliary connecting pipelines and power sources (or air supply sources), etc., for example, in combination with Figure 1 , Figure 2 As shown, the aforementioned air supply assembly also includes an intake pipe 32, an exhaust pipe 33, a main air supply pipe 34, and a circulating fan 35. One end of the intake pipe 32 is connected to the rehumidification chamber 1, and the other end is connected to the intake end of the circulating fan 35. One end of the exhaust pipe 33 is connected to the main air supply pipe 34, and the other end is connected to the exhaust end of the circulating fan 35. Multiple sets of air supply components 31 are all connected to the main air supply pipe 34. With this configuration, the circulation of gas inside the rehumidification chamber 1 can be achieved, and air can be supplied to the rehumidification chamber 1 through multiple sets of air supply components 31.

[0035] The aforementioned heating components are arranged in multiple sets, each corresponding to one of the multiple air supply components 311 in the air supply assembly, capable of heating the gas flowing through the two air supply ports respectively. Similarly, the aforementioned sensor components 5 are also arranged in multiple sets, each corresponding to one of the multiple air supply components 311 in the air supply assembly. These sensor components 5 can detect the actual temperature and humidity on the upper and lower sides of the conveyor belt assembly 2 respectively. For example, the aforementioned sensor components 5 include multiple temperature sensors and multiple humidity sensors. Multiple temperature sensors (e.g., two) are respectively disposed on the upper and lower sides of the conveyor belt assembly 2, and multiple humidity sensors (e.g., two) are respectively disposed on the upper and lower sides of the conveyor belt assembly 2.

[0036] Combination Figure 1 , Figure 2 As shown, the steam supply assembly includes multiple steam nozzles 6. These multiple steam nozzles 6 are all located on the upper side of the conveyor belt assembly 2 and are arranged in a one-to-one correspondence with the multiple sets of air supply assemblies 31. Specifically, in the vertical direction, the steam nozzles 6 are positioned directly in front of the space between two air supply components 311 in each set of air supply assemblies 31, thus enabling the multiple steam nozzles 6 to supply humid and hot gas to the corresponding positions (or areas) of the multiple sets of air supply assemblies 31. The atomizing humidification assembly 7 is connected to the multiple air supply components 311 in the air supply assembly. Specifically, the atomizing humidification assembly 7 includes an ultrasonic atomizer 71 and multiple connecting pipes (or multiple connecting sub-pipes) connected to the ultrasonic atomizer 71, with each connecting pipe (or connecting sub-pipe) connected to the multiple air supply components 311 in the air supply assembly.

[0037] The aforementioned control component is coupled to the electric damper, heating component, sensor component 5, steam supply component, and atomizing humidification component 7 (this coupling includes electrical and signal connections). The control component can control the operating states of the electric damper, heating component, steam supply component, and atomizing humidification component 7 based on the actual temperature and humidity detected by the multiple sensor components 5. Specifically, the control component can control the tilt angle of the electric damper based on the actual temperature and humidity detected by the multiple sensor components 5 to control the air supply flow rate at the air inlet. The control component can also control the start / stop status and operating power of the heating component, steam supply component, and atomizing humidification component 7 based on the actual temperature and humidity detected by the multiple sensor components 5.

[0038] Therefore, the tobacco pack rehumidification device provided in this embodiment, by setting up an air supply assembly capable of introducing circulating gas into the rehumidification chamber 1, the air supply assembly is configured to include multiple sets of air supply components 31 arranged along the extension direction of the rehumidification chamber 1, and the air supply components 31 are configured to include air supply elements 311 symmetrically arranged on opposite sides of the rehumidification chamber 1 and communicating with the rehumidification chamber 1, and each air supply element 311 is provided with two air supply ports located on the upper and lower sides of the conveyor belt assembly 2 respectively, and an electric baffle is provided at each air supply port; in addition, it is also provided with multiple air supply elements 311. The gas component 311 has multiple sets of heating components corresponding to each other, and multiple sets of sensor components 5 are set to correspond to each set of gas supply components 311. Multiple steam nozzles 6 of the steam supply component are set to correspond to each set of gas supply components 311 and are set to the atomizing humidification component 7 connected to the multiple gas supply components 311. In this way, when the tobacco pack needs to be rehumidified, the tobacco pack can be transported to the rehumidification box 1 by the conveyor belt component 2. Then, the steam supply component and the gas supply assembly work together to generate hot and humid circulating gas inside the rehumidification box 1 to rehumidify the tobacco pack. During the process of rehumidifying the cigarette packs using the aforementioned cigarette pack rehumidification device, multiple sensor components 5 corresponding to multiple air supply components 311 can be used to detect the actual temperature and humidity at different locations inside the rehumidification chamber 1 (i.e., the areas located on the upper and lower sides of the conveyor belt component 2, corresponding to the air supply components 311). The control component can control the heating components, steam nozzles 6, and atomizing humidification components 7 corresponding to different locations (or different air supply components 311) to work according to the actual temperature and humidity at these different locations. This enables precise detection and control of the actual temperature and humidity at different locations inside the rehumidification chamber 1, improves the uniformity of temperature and humidity inside the entire rehumidification chamber 1, and further improves the consistency of the rehumidification effect of different cigarette packs and different parts (i.e., the upper and lower sides) of the same cigarette pack inside the rehumidification chamber 1. Meanwhile, the aforementioned tobacco pack rehumidification equipment, through the cooperation of heating components, steam supply components, and atomizing humidification components 7, achieves the regulation of temperature and humidity inside the rehumidification chamber 1. It can independently and precisely regulate temperature and humidity during the tobacco pack rehumidification process, ensuring that both temperature and humidity meet the preset rehumidification requirements and guaranteeing the rehumidification effect.

[0039] In some embodiments, combined with Figure 2 , Figure 3As shown, the aforementioned air supply component 311 includes a first air supply pipe 3111, a second air supply pipe 3112, and a connecting pipe 3113. Both the first air supply pipe 3111 and the second air supply pipe 3112 extend along a second direction X2, which forms an angle with the aforementioned first direction X1 (for example, 90°) and is parallel to the horizontal plane. The connecting pipe 3113 is, for example, an L-shaped pipe. One end of the first air supply pipe 3111, one end of the second air supply pipe 3112, and one end of the connecting pipe 3113 are interconnected. Air supply ports are provided at the other ends of both the first air supply pipe 3111 and the second air supply pipe 3112. The first air supply pipe 3111 is located on the upper side of the conveyor belt assembly 2, and the second air supply pipe 3112 is located on the lower side of the conveyor belt assembly 2. This arrangement ensures that circulating hot and humid gas can be introduced into both the upper and lower sides of the conveyor belt assembly 2, while also facilitating the connection of the air supply pipelines.

[0040] In some embodiments, the heating assembly includes a first heating element and a second heating element. The first heating element is disposed in the first air supply pipe 3111, and the second heating element is disposed in the second air supply pipe 3112. With this arrangement, the first heating element and the second heating element can be used to heat the gas flowing through the first air supply pipe 3111 and the second air supply pipe 3112 respectively. In conjunction with the electric baffle, the internal temperature of the dehumidification chamber 1 can be more precisely controlled.

[0041] In some embodiments, such as Figure 3 As shown, the electric baffle installed at the air inlet of the first air supply pipe 3111 is the first electric baffle 41, and the electric baffle installed at the air inlet of the second air supply pipe 3112 is the second electric baffle 42. Both the first electric baffle 41 and the second electric baffle 42 are inclined towards the conveyor belt assembly 2. Specifically, taking the air supply component 311 installed on the right side of the conveyor belt assembly 2 as an example, combined with... Figure 2 , Figure 3 As shown, the first air supply pipe 3111 is located at the upper right of the conveyor belt assembly 2, and the second air supply pipe 3112 is located at the lower right of the conveyor belt assembly 2. Therefore, the first electric baffle 41 at the air supply port of the first air supply pipe 3111 tilts downwards to the left, and the second electric baffle 42 at the air supply port of the second air supply pipe 3112 tilts upwards to the left. The aforementioned control components can control the tilt angles of the first electric baffle 41 and the second electric baffle 42 respectively. Through this configuration, not only can the air supply volume at the air supply ports be adjusted by controlling the tilt angles of the first electric baffle 41 and the second electric baffle 42, but the airflow discharged from both air supply ports can also be directed towards the conveyor belt assembly 2, ensuring that the smoke packs on the conveyor belt assembly 2 can fully contact the humidified circulating gas, thus ensuring the rehumidification effect.

[0042] Furthermore, such as Figure 3As shown, a third electrically operated baffle 43 is also provided inside the first air supply pipe 3111, and the tilt direction of the third electrically operated baffle 43 is opposite to the tilt direction of the first electrically operated baffle 41. A fourth electrically operated baffle 44 is also provided inside the second air supply pipe 3112, and the tilt direction of the fourth electrically operated baffle 44 is opposite to the tilt direction of the second electrically operated baffle 42. A fifth electrically operated baffle 45 is also provided at the connection between the second air supply pipe 3112 and the connecting pipe 3113, and the tilt direction of the fifth electrically operated baffle 45 is the same as the tilt direction of the second electrically operated baffle 42. The above-mentioned control components can control the tilt angles of the third electrically operated baffle 43, the fourth electrically operated baffle 44, and the fifth electrically operated baffle 45 respectively. With this configuration, the tilt angles of multiple electrically operated baffles can be controlled separately by the control components, achieving fine control of the air supply volume.

[0043] On the other hand, this embodiment provides a method for rehumidifying tobacco packs, which employs the tobacco pack rehumidification equipment described in any of the above embodiments. The method includes:

[0044] Step S100: Place the cigarette pack to be re-moistened on the conveyor belt assembly 2, and use the conveyor belt assembly 2 to transport the cigarette pack to be re-moistened into the re-moistening box 1.

[0045] In step S200, multiple sets of sensor components 5 are used to detect the actual temperature and humidity at different locations inside the rehumidification chamber 1.

[0046] When the actual temperature is lower than the first preset temperature (i.e., when the actual temperature at a certain location inside the rehumidification chamber 1 is detected to be lower than the first preset temperature), the control component controls the corresponding heating component (i.e., the heating component corresponding to that location) to increase its operating power, and simultaneously controls the electric baffle at the corresponding air supply port (i.e., the air supply port corresponding to that location) to change its tilt angle, thereby increasing the air supply volume of the corresponding air supply port; when the actual temperature is higher than the second preset temperature, the control component controls the corresponding heating component to decrease its operating power, and simultaneously controls the electric baffle at the corresponding air supply port to change its tilt angle, thereby decreasing the air supply volume of the corresponding air supply port. The first preset temperature is lower than the second preset temperature.

[0047] For example, the above-mentioned air supply assembly includes five sets of air supply components 31, numbered sequentially as one, two, three, four, and five along the first direction X1. Each set of air supply components 31 includes two air supply elements 311 symmetrically arranged on the left and right. For example, the first set of air supply components 31 includes a left air supply element and a right air supply element symmetrically arranged. Further, each air supply element 311 is provided with two air supply ports located on the upper and lower sides of the conveyor belt assembly 2, respectively. For example, the left air supply element in the first set of air supply components 31 is provided with a left upper air supply port and a left lower air supply port. When the sensor assembly 5 detects the left air supply element... When the actual temperature of the area corresponding to the upper left air supply port is lower than the first preset temperature, the control component controls the heating component corresponding to that position to increase its operating power, and at the same time controls the electric baffle inside the upper left air supply port to change its tilt angle, so as to increase the air supply volume of the upper left air supply port; when the sensor component 5 detects that the actual temperature of the area corresponding to the upper left air supply port in the upper left air supply component is higher than the first preset temperature, the control component controls the heating component corresponding to that position to decrease its operating power, and at the same time controls the electric baffle inside the upper left air supply port to change its tilt angle, so as to decrease the air supply volume of the upper left air supply port.

[0048] When the actual humidity is lower than the first preset humidity (i.e., when the actual humidity at a certain location inside the humidification chamber 1 is detected to be lower than the first preset humidity), the control component controls the atomizing humidification component 7 and / or the steam supply component to increase their operating power, and simultaneously controls the electric baffle at the corresponding air supply port (i.e., the air supply port corresponding to that location) to change its tilt angle, thereby increasing the air supply volume of the corresponding air supply port; when the actual humidity is higher than the second preset humidity, the control component controls the atomizing humidification component 7 and / or the steam supply component to decrease their operating power, and simultaneously controls the electric baffle at the corresponding air supply port to change its tilt angle, thereby decreasing the air supply volume of the corresponding air supply port. The first preset humidity is lower than the second preset humidity. The specific principle of humidity adjustment is the same as the specific principle of temperature adjustment described above, so it will not be described again here. In addition, when controlling the operating power of the atomizing humidification component 7 and / or the steam supply component using the control component, if the absolute value of the difference between the actual humidity and the first preset humidity (or the second preset humidity) is small, only the operating state of the atomizing humidification component 7 can be controlled to keep the operating state of the steam supply component unchanged; if the absolute value of the difference between the actual humidity and the first preset humidity (or the second preset humidity) is large, only the operating state of the steam supply component can be controlled to keep the operating state of the atomizing humidification component 7 unchanged, or the operating states of both the steam supply component and the atomizing humidification component 7 can be controlled simultaneously.

[0049] In step S300, the rehydrated tobacco packs are transported to the outside of the rehydration box 1 using the conveyor belt assembly 2.

[0050] The method for rehydrating tobacco packs includes the aforementioned tobacco pack rehydration equipment, which has the same beneficial effects as the aforementioned tobacco pack rehydration equipment, and therefore will not be described again here.

[0051] In some embodiments, an intermediate preset temperature is provided between the first preset temperature and the second preset temperature. The difference between the intermediate preset temperature and the first preset temperature is equal to the difference between the second preset temperature and the intermediate preset temperature.

[0052] When the actual temperature detected by sensor component 5 is lower than the intermediate preset temperature and the actual temperature shows a continuous decreasing trend, the control component controls the corresponding heating component to increase its operating power, and simultaneously controls the electric baffle at the corresponding air supply port to change its tilt angle, thereby increasing the air supply volume at the corresponding air supply port. When the actual temperature detected by sensor component 5 is higher than the intermediate preset temperature and the actual temperature shows a continuous increasing trend, the control component controls the corresponding heating component to decrease its operating power, and simultaneously controls the electric baffle at the corresponding air supply port to change its tilt angle, thereby decreasing the air supply volume at the corresponding air supply port. Through the above settings, by combining the intermediate preset temperature with the actual temperature change trend to synchronously link the heating component and the electric baffle at the air supply port, predictive temperature control can be achieved. Adjustments can be made in advance when the temperature deviates from its trend, effectively reducing the temperature fluctuation range within the rehumidification chamber 1 and improving the response speed and control accuracy of temperature control.
