Description

Technical Field

[0001] This utility model relates to the field of dark tea fermentation technology, and in particular to a device for simulating a cellar environment for dark tea fermentation. Background Technology

[0002] The fermentation process of dark tea is extremely sensitive to temperature, humidity, oxygen concentration, and the microbial environment. Traditional cellar fermentation, with its natural advantages of constant temperature, high humidity, and low oxygen levels, imparts a unique flavor and quality to dark tea. With the large-scale development of the dark tea industry, cellar-like environment simulation equipment has emerged. This equipment precisely replicates the fermentation conditions of a cellar by artificially controlling parameters such as temperature, humidity, and gas composition, and is widely used in dark tea production enterprises and research institutions. This equipment typically includes the following core structure:

[0003] 1. Cabinet: As the main body of the equipment, it has good heat preservation, moisture retention and airtightness, providing a stable sealed space for the fermentation of dark tea;

[0004] 2. Temperature and humidity control system: Composed of temperature and humidity sensors, heating and cooling modules, and humidification and dehumidification devices, it monitors and adjusts the environmental parameters inside the chamber in real time;

[0005] 3. Gas circulation system: Maintains a micro-oxygen environment inside the chamber through a fan, gas filtration device, and carbon dioxide / oxygen concentration control module;

[0006] 4. Support plate: Used to place the black tea to be fermented. Its design must meet the requirements of black tea spreading area, air permeability and layered fermentation.

[0007] Currently, to achieve efficient fermentation of dark tea, equipment developers have adopted various designs and technologies. Some equipment uses modular temperature and humidity zone design to achieve precise control of different fermentation stages within the same equipment; others incorporate intelligent control systems to remotely monitor the fermentation process through IoT technology. Some high-end equipment employs biomimetic design to simulate the microbial environment of cellar soil, enhancing the fermentation quality of dark tea.

[0008] However, the above-mentioned implementation methods still have the following problems: In terms of bearing plate installation, traditional equipment mostly uses bolt fixing or slot nesting methods, which is cumbersome, requires tools and is time-consuming. In large-scale production, the efficiency is extremely low when the bearing plate is frequently replaced. In terms of bearing plate limiting, the existing structure relies on rigid limiting blocks or fixed guide rails. When the equipment vibrates during operation or the load on the bearing plate changes during the fermentation of black tea, the limiting components are prone to loosening, causing the bearing plate to shift position and affecting the uniformity of black tea fermentation. In response to this problem, this application proposes a solution that optimizes the bearing plate installation structure and limiting mechanism to achieve rapid installation and stable limiting of the bearing plate, ensuring the consistency and reliability of the black tea fermentation environment. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a cellar-like environment simulation device for black tea fermentation. It solves the problems of traditional equipment using bolt fixing or slot nesting methods for the installation of the support plate, which is cumbersome, requires tools, and is time-consuming. In large-scale production, frequent replacement of the support plate leads to extremely low efficiency. Regarding the limiting of the support plate, existing structures rely on rigid limiting blocks or fixed guide rails. When the equipment vibrates during operation or the load on the support plate changes during black tea fermentation, the limiting components are prone to loosening, causing the support plate to shift position.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A cellar-like environment simulation device for black tea fermentation includes an incubator. A support plate is installed inside the incubator. A protective cover is fixedly connected to the upper surface of the support plate, and a connecting plate is fixedly connected to the lower surface of the support plate. Two limiting blocks are movably engaged within the connecting plate. Return springs are fixedly connected to the opposing surfaces of the two limiting blocks. Two fixing blocks are fixedly connected to the front surface of the connecting plate. Lead screws are rotatably connected to the two fixing blocks. Sliding blocks are fixedly connected to the front surfaces of the two limiting blocks. Two sets of guide rails are fixedly connected to the inner wall of the incubator.

[0012] Preferably, both sets of guide rails are movably engaged with the support plate, the inner wall of the incubator is provided with two sets of limiting grooves, the two sets of limiting grooves are movably engaged with two limiting blocks respectively, and the left surface of the connecting plate is provided with a slot, in which a fixing plate is fixedly connected.

[0013] Preferably, both limiting blocks are movably engaged with the slots, both reset springs are fixedly connected to the fixing plate, both sliders have threaded holes through their surfaces, and both threaded holes are threaded into the lead screw.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The two limiting blocks will engage with the limiting grooves opened on the inner wall of the incubator, thereby fixing the support plate to the incubator. Installation can be completed without complicated tools or professional skills. Operators can quickly place the tea leaves to be fermented on the support plate and push them into the incubator, shortening preparation time. It is especially suitable for large-scale production or multi-batch experimental scenarios. The guide rails are evenly arranged, allowing the support plate to flexibly adjust the spatial layout inside the incubator according to the fermentation needs of the tea leaves, meeting the usage requirements.

[0016] 2. If the equipment is subjected to external vibration during operation, such as resonance of the production line, the vibration energy may be transmitted to the lead screw through the limit block, causing the lead screw to rotate unexpectedly and thus destroying the limit position. When the external impact force attempts to push the limit block, the return spring first deforms to absorb the energy, avoiding the impact force from acting directly on the lead screw thread pair. The damping characteristics of the return spring can consume the vibration energy, attenuate the vibration amplitude transmitted to the lead screw, and reduce the risk of micro-rotation of the lead screw due to vibration.

[0023] This application provides a simulated cellar environment device for black tea fermentation, effectively solving the problems of traditional equipment that uses bolt fixing or slot nesting for bearing plate installation. The installation process is cumbersome, requires tools, and is time-consuming, resulting in extremely low efficiency when frequently replacing bearing plates in large-scale production. Regarding bearing plate limiting, existing structures rely on rigid limiting blocks or fixed guide rails. When the equipment vibrates or the load on the bearing plate changes during black tea fermentation, the limiting components are prone to loosening, leading to bearing plate displacement. By optimizing the bearing plate installation structure and limiting mechanism, the device achieves rapid installation and stable limiting of the bearing plate, ensuring the consistency and reliability of the black tea fermentation environment.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that in terms of bearing plate installation, traditional equipment often uses bolt fixing or slot nesting methods, which are cumbersome, require tools, and are time-consuming. This results in extremely low efficiency when frequently replacing bearing plates in large-scale production. Regarding bearing plate positioning, existing structures rely on rigid limiting blocks or fixed guide rails. When the equipment vibrates during operation or the load on the bearing plate changes during black tea fermentation, the limiting components are prone to loosening, leading to bearing plate position displacement. The overall approach is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a simulated cellar environment device for black tea fermentation, including an incubator 1. A support plate 3 is installed inside the incubator 1. A protective cover 2 is fixedly connected to the upper surface of the support plate 3, and a connecting plate 7 is fixedly connected to the lower surface of the support plate 3. Two limiting blocks 6 are movably engaged within the connecting plate 7, and return springs 11 are fixedly connected to the opposing surfaces of the two limiting blocks 6. Two fixing blocks 9 are fixedly connected to the front surface of the connecting plate 7, and lead screws 8 are rotatably connected within the two fixing blocks 9. Slider blocks 10 are fixedly connected to the front surfaces of the two limiting blocks 6. Two sets of guide rails 4 are fixedly connected to the inner wall of the incubator 1. The entire incubator 1 uses sensors to monitor environmental parameters in real time. Combined with the control system and actuators, a closed-loop feedback is formed to precisely control environmental factors such as temperature, humidity, light, ventilation, and gas composition within the incubator, thus simulating natural conditions. For specific ecological environments, the tea leaves to be fermented are placed inside the protective cover 2 during use. At this time, the support plate 3 is snapped between the two guide rails 4. After the snapping is completed, the two sliders 10 fitted on the screw 8 are rotated and moved in opposite directions by the thread action. The movement of the two sliders 10 will drive the fixed limiting block 6 to move together. The movement of the two limiting blocks 6 will engage with the limiting groove 5 opened in the inner wall of the incubator 1, thereby completing the fixation between the support plate 3 and the incubator 1. Installation can be completed without complicated tools or professional skills. Operators can quickly place the tea leaves to be fermented on the support plate 3 and push them into the incubator 1, shortening the preparation time. It is especially suitable for large-scale production or multi-batch experimental scenarios. The guide rails 4 are arranged at equal intervals, so that the support plate 3 can flexibly adjust the spatial layout inside the incubator 1 according to the fermentation requirements of the tea leaves, meeting the usage needs.

[0027] Both sets of guide rails 4 are movably engaged with the support plate 3. Two sets of limiting grooves 5 are provided on the inner wall of the incubator 1, and each set of limiting grooves 5 is movably engaged with two limiting blocks 6. A slot 12 is provided through the left surface of the connecting plate 7, and a fixing plate 14 is fixedly connected within the slot 12. Both limiting blocks 6 are movably engaged with the slot 12. Both return springs 11 are fixedly connected to the fixing plate 14. Threaded holes 13 are provided through the surfaces of both sliders 10, and both threaded holes 13 are threadedly engaged with the lead screw 8. During installation, the two limiting blocks 6 are moved by the lead screw 8. To ensure the stability of the connection, the two limiting blocks 6... The limit blocks 6 are equipped with a return spring 11. During the engagement process, the two limit blocks 6 always have a pushing force. If the equipment is subjected to external vibration, such as production line resonance, the vibration energy may be transmitted to the lead screw 8 through the limit blocks 6, causing the lead screw 8 to rotate unexpectedly and thus destroying the limit position. When the external impact force attempts to push the limit blocks 6, the return spring 11 first deforms to absorb the energy, preventing the impact force from acting directly on the threaded pair of the lead screw 8. The damping characteristics of the return spring 11 can consume the vibration energy, attenuate the vibration amplitude transmitted to the lead screw 8, and reduce the risk of micro-rotation of the lead screw 8 due to vibration.

[0028] Among them, the incubator 1 is the main body of the equipment. The inner wall is equipped with guide rails 4 and limiting grooves 5. The temperature and humidity parameters are regulated by sensors and control systems to simulate the cellar environment and provide a stable space for the fermentation of black tea.

[0031] Guide rail 4: Fixed to the inner wall of incubator 1, it is movably connected to support plate 3, providing a sliding track for support plate 3, which facilitates its installation and allows for adjustment of the spatial layout according to fermentation requirements;

[0032] Limiting groove 5: It is formed on the inner wall of the incubator 1 and is movably engaged with the limiting block 6. When the support plate 3 is installed, it cooperates with the limiting block 6 to fix and limit the support plate 3 and the incubator 1.

[0033] Limiting block 6: It is movable and snapped into the connecting plate 7. The front surface is connected to the slider 10. It fixes the bearing plate 3 by snapping into the limiting groove 5. It is driven to move by the lead screw 8. The return spring 11 enhances the connection stability.

[0034] Connecting plate 7: Fixed to the lower surface of the bearing plate 3, with the inner movable locking limit block 6, and a slot 12 on the left surface for installing the reset spring 11 and the fixing plate 14, connecting the bearing plate 3 and the limiting component;

[0035] Lead screw 8: Rotatably connected inside the fixed block 9, its surface is threadedly engaged with the threaded hole 13 of the slider 10. When rotated, it drives the slider 10 to move the limit block 6, thereby realizing the installation and fixation of the bearing plate 3.

[0036] Fixed block 9: Fixed on the front surface of the connecting plate 7, used to rotate the connecting screw 8, providing support for the screw 8 so that it can stably drive the slider 10 and the limiting block 6 when rotating;

[0037] Slider 10: Fixed on the front surface of limit block 6, with threaded hole 13 on the surface that is threaded to screw 8. Driven by the rotation of screw 8, it moves limit block 6 to engage or disengage limit groove 5.

[0039] Slot 12: It is opened through the left surface of the connecting plate 7, and a fixing plate 14 is provided inside for installing the reset spring 11, providing installation space and movement guidance for the limit block 6 and the reset spring 11;

[0040] Threaded hole 13: It is opened through the surface of the slider 10 and threadedly connected to the lead screw 8, so that the slider 10 can be driven by the rotation of the lead screw 8, which drives the limit block 6 to move, thereby realizing the fixing and disassembly of the bearing plate 3.

[0041] Fixed plate 14: Fixed in the slot 12, used to connect the reset spring 11, providing fixed support for the reset spring 11, so that the reset spring 11 can act stably on the limit block 6, and enhance the connection stability.

[0042] Working principle:

[0043] The incubator 1 uses sensors to monitor environmental parameters in real time. Combined with a control system and actuators, it forms a closed-loop feedback mechanism to precisely regulate environmental factors such as temperature, humidity, light, ventilation, and gas composition within the incubator, simulating a natural or specific ecological environment. During use, the tea leaves to be fermented are placed inside the protective cover 2. The support plate 3 is then snapped between two guide rails 4. After snapping, rotating the lead screw 8 causes two sliding blocks 10 mounted on it to move in opposite directions due to the threaded action. This movement of the two sliding blocks 10 moves the fixed limiting blocks 6, which engage with the limiting grooves 5 on the inner wall of the incubator 1, thus fixing the support plate 3 to the incubator 1. Installation can be completed without complex tools or specialized skills. Operators can quickly place the tea leaves to be fermented on the support plate 3 and push them into the incubator 1, shortening preparation time. This is particularly suitable for large-scale production or... In multiple batches of experimental scenarios, the guide rails 4 are arranged at equal intervals, allowing the support plate 3 to flexibly adjust the spatial layout inside the incubator 1 according to the tea fermentation requirements, thus meeting the usage needs. During installation, the two limit blocks 6 are driven by the lead screw 8 to move. To ensure the stability of the connection, the two limit blocks 6 are provided with return springs 11. At this time, the two limit blocks 6 always have a pushing force during the locking process. If the equipment is subjected to external vibration during operation, such as production line resonance, the vibration energy may be transmitted to the lead screw 8 through the limit blocks 6, causing the lead screw 8 to rotate unexpectedly, thereby damaging the limit position. When the external impact force attempts to push the limit blocks 6, the return spring 11 first deforms to absorb the energy, avoiding the impact force from directly acting on the threaded pair of the lead screw 8. The damping characteristics of the return spring 11 can consume vibration energy, attenuate the vibration amplitude transmitted to the lead screw 8, and reduce the risk of micro-rotation of the lead screw 8 due to vibration.

[0044] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
