The equipment has a complex structure and high maintenance costs, which is not conducive to large-scale production applications. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies, and this utility model provides a tobacco processing equipment.

[0005] This utility model provides the following technical solution: A tobacco processing device includes a base frame, a conveyor body, a vibration assembly, a heating assembly, and a control module.

[0006] The feeding machine body is mounted on the base frame, and the feeding machine body is provided with a material passage for placing tobacco drying shreds; the vibration component is mounted on the base frame, and the vibration component can drive the feeding machine body to vibrate periodically relative to the base frame, thereby driving the tobacco in the material passage to tumble and move; the heating component is mounted on the feeding machine body for heating the inside of the material passage; the control module is connected to the vibration component and the heating component respectively, and controls them.

[0007] As a further improvement to the above technical solution, the vibration assembly includes spring supports and a vibration motor. There are multiple spring supports, which are evenly distributed between the base frame and the conveyor body. The vibration motor is mounted on the base frame, and the control module can adjust the working state of the vibration motor.

[0008] As a further improvement to the above technical solution, the heating assembly includes multiple electric heating tubes, which are evenly distributed at the top and bottom of the material passage, and the control module can adjust the heating power of the electric heating tubes.

[0009] As a further improvement to the above technical solution, a temperature sensor is provided in the material passage, and the temperature sensor is connected to the control module for data transmission.

[0010] As a further improvement to the above technical solution, multiple steam nozzles are evenly distributed on the inner wall of the material passage, and the steam nozzles are connected to the external steam supply system through the conveying pipe.

[0011] As a further improvement to the above technical solution, a dehumidification pipe is also provided above the material conveying body. One end of the dehumidification pipe is connected to the interior of the material passage, and the other end of the dehumidification pipe is connected to the suction device.

[0012] As a further improvement to the above technical solution, the dehumidification pipe is provided with two suction ports.

[0015] As a further improvement to the above technical solution, a movable cover plate is detachably installed at the upper end of the material passage.

[0016] Compared with related technologies, the beneficial effects of this utility model are: The tobacco processing equipment provided by this utility model allows the operator to first activate the heating component during the processing of tobacco materials, initiating a preheating phase to ensure the equipment reaches a suitable processing temperature. Simultaneously, the vibration component is also activated to prepare for the subsequent tumbling and movement of the tobacco materials.

[0017] After the equipment has preheated and the vibration has stabilized, the operator feeds the tobacco material into the starting position of the feeding channel. Once the tobacco material falls into the feeding channel, it begins to tumble and move under the continuous and stable vibration generated by the vibrating components. This tumbling movement not only helps the tobacco material to be heated evenly, but also effectively prevents material accumulation or sticking, ensuring that each piece of tobacco is fully processed.

[0018] As the tobacco material tumbles and moves, the heating element continuously releases heat to dry it. The tobacco material moves slowly along the conveyor channel due to vibration, gradually losing excess moisture and becoming drier and looser. Finally, the thoroughly dried tobacco material is smoothly discharged from the end of the conveyor channel.

[0019] During this processing, operators can precisely adjust the heating power of the heating components via the control module according to the different temperature requirements and drying difficulties of the tobacco materials. Whether high-temperature rapid drying or low-temperature slow drying is required, it can be achieved accordingly. Simultaneously, parameters such as the amplitude and frequency of the vibration components can also be adjusted according to actual needs to ensure that the tumbling effect and speed of the tobacco materials in the material passage are appropriate. Through this intelligent parameter adjustment method, the tobacco processing equipment provided by this invention can achieve uniform drying of tobacco materials of different states and specifications. Whether it is long, thin tobacco shreds or blocky tobacco sheets, they can all receive high-quality processing in the equipment.

[0029] Combination Figure 1 , Figure 2 As shown, an embodiment of this utility model provides a tobacco processing device, including a base frame 100, a material conveyor body 200, a vibration component 300, a heating component 400, and a control module.

[0030] The feeding machine body 200 is mounted on the base frame 100, and the feeding machine body 200 is provided with a material passage 210 for placing tobacco drying shreds; the vibration component 300 is disposed on the base frame 100, and the vibration component 300 can drive the feeding machine body 200 to vibrate periodically relative to the base frame 100, thereby driving the tobacco in the material passage 210 to tumble and move; the heating component 400 is disposed on the feeding machine body 200 for heating the inside of the material passage 210; the control module is connected to the vibration component 300 and the heating component 400 respectively, and controls them; the control module specifically includes a PLC control system, which facilitates accurate adjustment of the working state of the vibration component 300 and the heating component 400.

[0031] In the tobacco processing equipment provided in this embodiment, during the processing of tobacco materials, the operator first turns on the heating component 400 to put it into the preheating stage, ensuring that the internal processing temperature of the equipment reaches a suitable level. At the same time, the vibration component 300 is also activated to prepare for the subsequent tumbling and movement of the tobacco materials.

[0032] After the equipment has preheated and the vibration has stabilized, the operator feeds the tobacco material into the starting position of the feeding channel 210. Once the tobacco material falls into the feeding channel 210, it begins to tumble and move under the continuous and stable vibration generated by the vibration component 300. This tumbling movement not only helps the tobacco material to be heated evenly, but also effectively prevents the material from piling up or sticking together, ensuring that each piece of tobacco is fully processed.

[0033] During the tumbling and movement of the tobacco material, the heating element 400 continuously releases heat to heat and dry the material. The tobacco material moves slowly along the conveying channel 210 due to vibration, gradually losing excess moisture and becoming drier and looser. Finally, the fully dried tobacco material is smoothly discharged from the end of the conveying channel 210.

[0034] During this processing, the operator can precisely adjust the heating power of the heating component 400 through the control module according to the different temperature requirements and drying difficulty of the tobacco material. Whether high-temperature rapid drying or low-temperature slow drying is required, it can be achieved accordingly. Simultaneously, the amplitude and frequency of the vibration component 300 can also be adjusted according to actual needs to ensure that the tumbling effect of the tobacco material in the material passage 210 and the speed at which it passes through the material passage 210 are appropriate. Through this intelligent parameter adjustment method, the tobacco processing equipment provided in this embodiment can achieve uniform drying of tobacco materials of different states and specifications. Whether it is long, thin tobacco shreds or blocky tobacco sheets, they can all receive high-quality processing in the equipment.

[0035] In some specific embodiments, the vibration assembly 300 includes a spring support 310 and a vibration motor 320. There are multiple spring supports 310, which are evenly distributed between the base frame 100 and the material conveyor body 200. The vibration motor 320 is mounted on the base frame 100. The control module can adjust the working state of the vibration motor 320. Through the control module, the operator can flexibly change the operating parameters of the vibration motor 320 according to different processing requirements.

[0036] When the vibrating motor 320 starts working, it generates vibrations with a certain frequency and amplitude. This vibration is transmitted to the connected conveyor body 200, causing it to periodically compress the spring support member 310. During the compression of the spring support member 310, the spring support member 310 undergoes elastic deformation, storing energy; when the force generated by the vibrating motor 320 decreases or disappears, the spring support member 310 releases energy, pushing the conveyor body 200 to rebound. This process repeats continuously, allowing the conveyor body 200 to vibrate continuously, causing the tobacco material placed inside to tumble and move with the vibration, thus achieving uniform processing.

[0037] Specifically, controlling the power of the vibrating motor 320 using the control module is a crucial and simple operation. The power of the vibrating motor 320 directly determines its output force, which in turn affects the relative vibration frequency and amplitude between the conveyor body 200 and the base frame 100. When an increase in vibration frequency and amplitude is needed, simply increasing the power of the vibrating motor 320 via the control module will generate stronger vibrations, causing the conveyor body 200 to more violently compress the spring support 310, achieving a higher vibration frequency and greater amplitude. Conversely, when a decrease in vibration frequency and amplitude is needed, simply reducing the power of the vibrating motor 320 will suffice. This adjustment method is simple and efficient; operators can quickly and accurately adjust the vibration state of the conveyor body 200 to meet the needs of processing different tobacco materials without complex procedures.

[0038] In some specific embodiments, the heating assembly 400 includes multiple electric heating tubes 410, which are evenly distributed at the top and bottom of the material passage 210. From a heating principle perspective, simultaneously laying electric heating tubes 410 at the top and bottom of the material passage 210 creates a dual heating effect from both above and below. When the tobacco material is conveyed within the material passage 210, it is simultaneously subjected to heat radiation from both above and below. This all-around heating method effectively avoids overheating or underheating of the tobacco material due to uneven local heating, thereby greatly improving the uniformity of heating. The control module can adjust the heating power of the electric heating tubes 410. In actual operation, the operator can flexibly adjust the heating power of the electric heating tubes 410 based on factors such as the initial humidity, type characteristics, and preset final dryness of the tobacco material through the control module.

[0039] For example, when processing tobacco materials with high initial moisture content and difficult drying, operators can appropriately increase the heating power of the electric heating element 410 to rapidly raise the temperature within the material passage 210 and accelerate moisture evaporation. Conversely, when processing tobacco materials with low initial moisture content and easy drying, the heating power of the electric heating element 410 can be reduced to avoid damaging the quality of the tobacco materials due to excessive temperature. This dynamic adjustment of the heating power of the electric heating element 410 allows for accurate control of the heating temperature of the tobacco materials, ensuring that the entire heating process remains stable and controllable.

[0040] This precise temperature control method not only ensures the processing quality of tobacco materials, enabling them to achieve the ideal drying effect, but also significantly improves the operational stability of the tobacco processing equipment in this embodiment.

[0041] In some specific embodiments, a temperature sensor is installed inside the material conveying channel 210, and the temperature sensor is data-connected to the control module. During actual operation, the temperature sensor continuously monitors the temperature inside the material conveying channel 210 in real time. It continuously collects temperature information at various locations within the material conveying channel 210 and converts this raw data into electrical signals, which are then transmitted to the control module via the data connection line.

[0042] Once the control module receives the data from the temperature sensor, it quickly and meticulously compares this actual temperature data with its internally preset temperature parameters. These internal temperature parameters are set comprehensively based on factors such as the characteristics of the tobacco material, drying process requirements, and past experimental data, representing the optimal temperature range required for drying the tobacco material within the material passage 210.

[0043] By comparison, if the control module detects that the actual temperature is higher than the internally set upper temperature limit, it means that the temperature inside the material passage 210 is too high, which may cause over-drying or even scorching of the tobacco material. At this time, the control module will immediately issue a command to reduce the heating power of the electric heating tube 410. Specifically, it will reduce the current or voltage supplied to the electric heating tube 410, thereby reducing the heat generated by the electric heating tube 410 and causing the temperature inside the material passage 210 to gradually decrease.

[0044] Conversely, when the control module determines that the actual temperature is lower than the internally set lower limit, it indicates that the temperature in the material passage 210 is insufficient and cannot effectively dry the tobacco material. At this time, the control module will correspondingly increase the heating power of the electric heating tube 410 and increase the current or voltage transmission, so that the electric heating tube 410 generates more heat and raises the temperature in the material passage 210.

[0045] This adjustment method, based on comparing real-time temperature data with preset parameters, ensures that the temperature within the material passage 210 is always maintained within a suitable range. This automatic adjustment mechanism not only avoids the errors and lags that may result from manual adjustment but also significantly improves the accuracy and timeliness of temperature control. Ultimately, it achieves automatic and efficient temperature regulation within the material passage 210, providing a stable and suitable drying environment for the tobacco material, thereby ensuring the quality of the drying process and enabling the processed tobacco products to meet higher quality standards.

[0046] In some specific embodiments, multiple steam nozzles 510 are evenly distributed on the inner wall of the material passage 210. The steam nozzles 510 are connected to an external steam supply system through a conveying pipe. Specifically, the steam supply system consists of a steam generator, a steam conveying pipe, a steam regulating valve, and upper and lower steam injection assemblies. The steam generator is the core component of the entire system; it can heat water and convert it into high-temperature, high-pressure steam, providing a stable steam source for the system.

[0047] The steam delivery pipelines are responsible for delivering the steam generated by the steam generator to the various steam nozzles 510. These pipelines are designed and laid with full consideration of the steam flow characteristics and pressure loss, and adopt reasonable pipe diameters and layouts to ensure that the steam can reach the steam nozzles 510 at appropriate flow rates and pressures.

[0048] The steam regulating valve is a key component for controlling steam flow and pressure. It can precisely adjust the amount of steam passing through based on preset parameters, thereby controlling the intensity and range of steam ejected from the steam nozzle 510. By adjusting the steam regulating valve, operators can flexibly adjust the steam supply according to factors such as the type of tobacco material, initial humidity, and rehumidification requirements, achieving precise control over the rehumidification process.

[0049] The upper and lower steam injection components are composed of two separate steam injection parts, each consisting of a steam nozzle 510, which further optimizes the steam injection effect. The upper steam injection component is mainly responsible for injecting steam into the upper space of the material passage 210, so that the surface of the tobacco material can quickly absorb the moisture in the steam; the lower steam injection component injects steam into the bottom of the material passage 210, and through the rising action of the steam, the inside of the tobacco material can also fully absorb moisture, thereby achieving synchronous rehydration inside and out.

[0050] During actual operation, the steam supply system, based on preset parameters and through the coordinated operation of various components, stably supplies steam at appropriate temperature and pressure into the material passage 210 via the steam nozzle 510. When the steam is ejected from the steam nozzle 510, it quickly diffuses within the material passage 210, making full contact with the tobacco material. Under the action of the steam, the tobacco material absorbs moisture, gradually reaching a suitable humidity level, thus completing the rehumidification process. This rehumidification method effectively improves the physical and chemical properties of the tobacco material, enhancing its processing performance and quality, and laying a solid foundation for subsequent tobacco processing steps.

[0051] In some specific embodiments, a dehumidification pipe 520 is also provided above the conveying body 200. One end of the dehumidification pipe 520 is connected to the interior of the material passage 210, and the other end is connected to the suction device. During actual operation, when the tobacco material in the material passage 210 is rehumidified, steam is continuously injected into the material passage 210, causing the tobacco material to absorb moisture. However, if the amount of steam injected is too large or the rehumidification time is too long, the humidity in the material passage 210 may become too high. At this time, the dehumidification pipe 520 plays a crucial role. After the suction device is started, a negative pressure is formed in the dehumidification pipe 520. Excess steam and humid air in the material passage 210 are quickly sucked out through the dehumidification pipe 520 under the action of the pressure difference.

[0052] This dehumidification method has significant advantages. On the one hand, it can promptly remove excess steam, preventing excessive humidity in the material passage 210 from affecting the rehydration quality of the tobacco material. For example, if the humidity is too high, the tobacco material may absorb too much moisture, causing its moisture content to exceed the process requirements, affecting subsequent processing steps and product quality. On the other hand, by reasonably controlling the dehumidification process, a relatively stable humidity environment can be maintained within the material passage 210, allowing the tobacco material to rehydrate evenly under suitable humidity conditions.

[0053] In some specific embodiments, the dehumidification pipe 520 is equipped with two suction ports. One suction port of the dehumidification pipe 520 is connected to the interior of the material passage 210, and the other suction port is located above the outlet of the material passage 210. During actual operation, when the suction equipment is started, a stable negative pressure is formed inside the dehumidification pipe 520. The two suction ports work simultaneously: the suction port inside the material passage 210 quickly draws the steam in the passage into the pipe, while the suction port above the outlet promptly removes the steam overflowing from the passage. This simultaneous suction method greatly improves the dehumidification efficiency and can quickly reduce the humidity inside the material passage 210 and near its outlet.

[0054] For example, when processing tobacco materials with high humidity and difficult rehydration, a large amount of steam will be rapidly generated and accumulated in the material passage 210. At this time, the two suction ports work together to quickly expel the steam, avoiding uneven or excessive rehydration of the tobacco material due to excessive humidity. Furthermore, by simultaneously suctioning steam from different locations, a relatively stable humidity environment can be maintained within the material passage 210, ensuring that the tobacco material remains under suitable humidity conditions throughout the rehydration process. This guarantees the effectiveness of the rehydration treatment and improves product quality and stability.

[0055] In some specific embodiments, a humidity sensor is installed within the material conveying channel 210, and the humidity sensor is data-connected to the control module. During actual operation, the humidity sensor continuously monitors the humidity within the material conveying channel 210 in real time and converts this raw humidity detection data into electrical signals. Subsequently, these electrical signals are transmitted to the control module via the data connection line.

[0056] After receiving the detection data transmitted from the humidity sensor, the control module quickly compares the actual humidity data with its internal preset parameters. These internal preset parameters are determined based on factors such as the characteristics of the tobacco material, the requirements of the rehumidification process, and past experimental data and production experience, and represent the optimal humidity range required for the rehumidification treatment of the tobacco material in the material passage 210.

[0057] Through comparative analysis, if the control module detects that the actual humidity exceeds the internally preset humidity limit, it means that the humidity in the material passage 210 is too high, which may adversely affect the rehumidification quality of the tobacco material, such as causing excessive moisture content or mold growth. In this case, the control module will immediately issue a command to increase the power of the suction device. Specifically, it will send corresponding control signals to the suction device to increase the motor speed or increase the suction force, enabling the suction device to extract excess steam and humid air from the material passage 210 more quickly and effectively, thereby reducing the humidity within the passage.

[0058] Conversely, when the control module determines that the actual humidity is lower than the internally preset lower limit, it indicates that the humidity in the material passage 210 is insufficient and cannot meet the requirement for sufficient rehydration of the tobacco material, which may lead to uneven rehydration and excessively hard texture. At this time, the control module will issue a corresponding instruction to reduce the power of the suction equipment, reduce the operating intensity of the suction equipment, reduce the amount of air sucked into the material passage 210, so that more steam and moisture can be retained in the passage, thereby increasing the humidity.

[0059] By using this adjustment method based on comparing real-time humidity data with preset parameters, the control module can precisely control the power of the suction equipment, ensuring that the humidity within the material passage 210 remains stable and suitable. This intelligent humidity adjustment mechanism not only avoids the errors and lags that may result from manual adjustment, but also greatly improves the accuracy and timeliness of humidity control, providing a stable and suitable rehumidification environment for tobacco materials. This effectively guarantees the quality and stability of the tobacco material rehumidification process, enabling the processed tobacco products to meet higher quality standards.

[0060] like Figure 3As shown, in some specific embodiments, the bottom surface of the material passage 210 has an angle α with the horizontal plane, and the value of α ranges from 4° to 8°. The material passage 210 is tilted at this angle based on multiple considerations. During the processing of tobacco materials, the material passage 210 is usually subjected to vibration by a vibration device. This vibration causes the tobacco material in the passage to tumble, thereby increasing the contact area between the material and the surrounding environment (such as steam, hot air, etc.), which is beneficial for drying and rehydration processes.

[0061] When the material conveying channel 210 is tilted at an angle of 4° to 8°, it ensures that the tobacco material passes through the channel stably and reliably during the tumbling process caused by vibration. Specifically, within this angle range, the tobacco material moves forward in an orderly manner along the tilted bottom surface under the combined action of gravity and vibration. On the one hand, a suitable tilt angle provides sufficient downward force, preventing material from accumulating in the channel and effectively reducing the probability of material piling. Once material piling occurs, it not only hinders the normal transmission of materials but may also lead to uneven material processing in certain areas, affecting the final drying and rehydration quality. On the other hand, this angle range avoids problems caused by excessive tilt angles. If the tilt angle exceeds 8°, the downward speed of the tobacco material in the material conveying channel 210 will be too fast, greatly shortening the residence time of the material in the channel. The drying and rehydration treatment of tobacco material is a process that requires a certain amount of time. Only when the material stays in the channel for a sufficient time can it fully absorb the moisture or heat from the steam or hot air to achieve the ideal treatment effect. If the residence time is too short, the material may not be fully dried or rehydrated, resulting in a decline in product quality.

[0062] For example, in actual production, when processing tobacco materials with high moisture content and dense texture, if the inclination angle of the material passage 210 is too small (less than 4°), the material is prone to accumulate in certain parts of the passage due to insufficient sliding force during vibration and tumbling, forming material piles that affect the entry and processing of subsequent materials. Conversely, if the inclination angle is too large (greater than 8°), these materials will quickly slide through the passage and be discharged from the outlet before fully contacting the steam for rehydration, resulting in substandard moisture content in the rehydrated material and affecting the overall quality of the tobacco product.

[0063] In some specific embodiments, the upper end of the material passage 210 is detachably equipped with a movable cover plate 220. Common connection methods include, but are not limited to, snap-fit ​​connections and bolt connections. In actual production, when it is necessary to clean or maintain the inside of the material passage 210, the operator can easily and quickly open the movable cover plate 220 from above as needed. For example, after processing a batch of tobacco materials, if a large amount of tobacco debris and dust is found remaining in the passage, the movable cover plate 220 can be quickly removed, and professional cleaning tools, such as brushes and vacuum cleaners, can be used to thoroughly clean the inside of the passage, completely removing the accumulated impurities and ensuring the cleanliness and hygiene of the passage.

[0064] Furthermore, the removability of the movable cover 220 plays a crucial role when certain components inside the material passage 210 malfunction or are damaged and require repair or replacement. Operators do not need to perform extensive disassembly of the material passage 210; they can simply open the movable cover 220 to directly access the relevant internal components, quickly and accurately locate the fault point, and perform repair or replacement, greatly shortening maintenance time and improving production efficiency.
