Description

Technical Field

[0001] This invention relates to the field of tea processing technology, specifically to a tea fermentation and frying equipment with multi-stage airflow control. Background Technology

[0002] In the tea processing industry, fermentation and roasting are key steps that determine tea quality, and airflow control technology plays a crucial role in these two stages. With the industrialization and automation of tea processing, fermentation and roasting equipment integrating multi-stage airflow control functions has gradually become mainstream. By precisely controlling parameters such as airflow temperature, humidity, and flow rate, it can effectively improve the uniformity of tea fermentation and the stability of roasting, while reducing the cost of manual intervention.

[0003] However, existing tea fermentation and frying equipment with multi-stage airflow control still has two prominent problems in actual operation, which seriously affect processing efficiency and tea quality:

[0004] On the one hand, the air outlet is easily blocked by tea leaves. During the fermentation stage, the moisture or sticky substances contained in the tea leaves are easily absorbed and accumulated near the air outlet under the action of airflow. During the frying stage, the tea leaves may produce residue and powder after being stir-fried. These small particles are easily stuck in the grille or duct gaps of the air outlet as they move with the airflow, causing airflow obstruction. Once the air outlet is blocked, it will not only disrupt the airflow balance inside the equipment, causing parameters such as temperature, humidity, and oxygen concentration to deviate from the set values, resulting in insufficient fermentation of the tea leaves and uneven heating during frying, but it may also cause local overload of the equipment due to a sudden increase in airflow pressure, shortening its service life.

[0005] On the other hand, the air outlet duct is prone to loosening under airflow pressure. During multi-stage airflow control, the equipment needs to frequently adjust the airflow rate and pressure. For example, the switching between the low-pressure airflow in the early stage of fermentation and the high-temperature, high-pressure airflow in the roasting stage causes periodic changes in airflow pressure, resulting in continuous impact and vibration at the connection between the air outlet duct and the equipment cavity. Traditional connection methods, such as bolt fixing and snap-fit ​​connections, are prone to problems such as increased gaps and fastener fatigue failure under long-term alternating stress, leading to loosening or even detachment of the duct. This not only causes airflow leakage and reduces control accuracy, but also generates abnormal noise and wear due to the duct shaking and collision with other components, posing a safety hazard.

[0006] Therefore, a tea fermentation and frying equipment with multi-stage airflow control was proposed to solve the above problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a tea fermentation and frying device with multi-stage airflow control, thereby solving the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a tea fermentation and frying equipment with multi-stage airflow control, comprising: a tea fermentation machine and a first component installed thereon, the first component comprising: a positioning shell for positioning connection, a tube groove body fixedly connected inside the positioning shell, a fan-shaped groove being formed on the outer ring surface of the tube groove body, and eight fan-shaped grooves being formed at equal intervals around the center of the tube groove body;

[0009] The first component also includes: a first positioning ring for triggering and pushing multiple components, the first positioning ring being fitted and connected to one end face of the fan-shaped groove, and a first sliding body being fixedly connected to the side near the fan-shaped groove, the first sliding body being equidistantly arranged with four of them around the center of the first positioning ring, the outer ring of the first sliding body away from the first positioning ring being rotatably connected with two sets of first connecting rods, the end of the first connecting rod away from the first sliding body being rotatably connected with a first abutting block, the first abutting block being a one-twelfth arc surface;

[0010] The second component is used to scrape off the dust generated during the tea processing inside the tea fermentation machine.

[0011] Preferably, the first component further includes: a second positioning ring that is fitted and connected to the side of the first positioning ring away from the fan-shaped groove; a second sliding groove body is fixedly connected to the side of the second positioning ring close to the first positioning ring; four second sliding groove bodies are arranged around the center of the second positioning ring; two sets of second connecting rods are rotatably connected to the end of the second sliding groove body away from the second positioning ring; and a second abutting block is rotatably connected to the end of the second connecting rod away from the second sliding groove body; the second abutting block is a two-twelfths arc surface.

[0012] Preferably, the first and second abutting blocks are arranged alternately, the first and second positioning rings are both driven by an external telescopic drive device, the first and second sliding grooves are both slidably connected in the fan-shaped groove, and one end of the positioning housing is provided with an annular through groove.

[0013] Preferably, the tea fermentation machine has a device wall on one side, and a connecting cavity is formed in the device wall. The connecting cavity is composed of chambers of different diameters. The positioning shell is slidably inserted into the connecting cavity. An air outlet pipe is provided in the connecting cavity. The air outlet end of the air outlet pipe is located inside the tea fermentation machine. An air supply hose is fixedly connected to the end of the air outlet pipe away from the tea fermentation machine. A large-diameter external pipe is provided at the end of the air outlet pipe away from the air supply hose. The air supply hose is connected to an external air supply device.

[0014] Preferably, the second component includes: a wind speed sensor fixedly connected to one end of the air outlet pipe near the air supply hose; an annular groove is formed on the outer ring of the air outlet pipe; an electrically controlled telescopic rod is fixedly connected to one end of the annular groove near the air supply hose; a magnetic ring is fixedly connected to one end of the output shaft of the electrically controlled telescopic rod; and the magnetic ring is slidably connected to the annular groove.

[0015] Preferably, the wind speed sensor is electrically connected to the first positioning ring and the second positioning ring via the same controller, and the electrically controlled telescopic rod is controlled by an external controller.

[0016] Preferably, a metal plate is slidably connected inside the air outlet pipe, and a funnel block is rotatably connected to the end of the metal plate away from the air supply hose. A guide body is fixedly connected to the side of the funnel block away from the metal plate, and a conical block is fixedly connected to the side of the guide body away from the funnel block. An arc-shaped groove is symmetrically opened inside the end of the air outlet pipe near the outer pipe. Multiple through holes are provided inside the funnel block, the guide body, and the conical block.

[0017] Preferably, the air outlet pipe and the magnet ring are concentric rings, and two guide posts are symmetrically fixedly connected to the guide body. The two guide posts on the guide body are slidably connected in two arc-shaped grooves.

[0018] Compared with the prior art, the present invention provides a tea fermentation and frying device with multi-stage airflow control, which has the following beneficial effects:

[0019] 1. By setting the first component, the annular groove structure opened on the positioning housing provides a limiting reference for the first and second abutment blocks, so that the movement and deflection of the first and second abutment blocks always revolve around the axis of the positioning housing, ensuring uniform force on the connection part and avoiding local wear caused by offset. This provides a foundation for the stable connection between the air supply hose, air outlet pipe and device wall under multi-stage airflow impact. In addition, the fitting design of the front arc surface of the first and second abutment blocks with the inner wall of the annular groove of the positioning housing can disperse the contact stress and avoid local wear. The movement into the connection cavity can fill the connection gap and offset the deformation caused by the airflow pressure impact. This is applicable to the alternating strain environment during multi-stage airflow switching.

[0020] 2. By using the first component in conjunction with the airflow intensity, airflow leakage caused by loose connections between the air supply hose, air outlet pipe, and tea fermentation machine is avoided. Combined with feedback from the wind speed sensor on the airflow intensity, the stronger the airflow, the tighter the air supply hose and air outlet pipe are fastened to the tea fermentation machine. This design ensures that airflow parameters at each stage are transmitted stably according to the preset program, providing a precise and controllable environment for tea processing. It avoids the problem of traditional fastening methods easily failing due to fatigue under long-term alternating airflow pressure, leading to loosening of the air outlet pipe, which in turn causes equipment vibration, abnormal noise, or even component collisions. Moreover, dynamic fastening can be achieved without manual intervention, adapting to the airflow characteristics of the entire tea processing process: the low-pressure airflow in the early stage of fermentation triggers basic fastening, avoiding stress accumulation in components due to excessive tightening; the high-pressure airflow in the roasting stage automatically enhances the fastening strength to cope with extreme working conditions.

[0021] 3. By using the magnetic ring and metal plate in the second component, non-contact power transmission is achieved through magnetic attraction. The metal plate can be moved synchronously without the need for a mechanical connection, reducing friction and wear between components. This is especially suitable for dusty environments in tea processing, reducing the risk of jamming caused by mechanical contact. At the same time, it simplifies the internal structure of the air outlet pipe and avoids the obstruction of airflow by complex transmission components.

[0022] 4. The shape of the funnel block is adapted to the inner diameter of the outlet pipe. During the rotation and forward movement, it can scrape and guide the accumulated material on the inner wall of the pipe, and gather the debris towards the pipe opening. At the same time, its funnel-shaped structure can reduce the resistance to airflow and ensure the pressure stability during multi-stage airflow control. The sliding of the guide column on the guide body in the arc groove causes the guide body to drive the entire structure to rotate and move forward along the arc path. This increases the contact area between the funnel block, the cone block and the inner wall of the pipe and the spiral friction path. The rotation action also enhances the peeling effect of stubborn dust and avoids obstruction of airflow during the processing. Attached Figure Description

[0047] A further embodiment: Please refer to Figures 8 to 10 As shown:

[0048] The second component includes: a wind speed sensor 31 fixedly connected to one end of the air outlet pipe 15 near the air supply hose 14; an annular groove 32 is provided on the outer ring of the air outlet pipe 15; an electrically controlled telescopic rod 33 is fixedly connected to one end of the annular groove 32 near the air supply hose 14; a magnetic ring 34 is fixedly connected to one end of the output shaft of the electrically controlled telescopic rod 33; and the magnetic ring 34 is slidably connected in the annular groove 32.

[0050] A metal plate 35 is slidably connected inside the air outlet pipe 15. A funnel block 36 is rotatably connected to the end of the metal plate 35 away from the air supply hose 14. A guide body 37 is fixedly connected to the side of the funnel block 36 away from the metal plate 35.

The reciprocating movement of the conical block 38 inside the air outlet pipe 15 can interfere with the airflow direction. A symmetrical arc groove 39 is opened inside the end of the air outlet pipe 15 near the outer pipe. Multiple through holes 310 are provided in the funnel block 36, the guide body 37 and the conical block 38. The through holes 310 are used for airflow.

[0051] The air outlet pipe 15 and the magnetic ring 34 are concentric rings. Two guide posts are symmetrically fixedly connected on the guide body 37. The two guide posts on the guide body 37 are slidably connected in two arc-shaped grooves 39 respectively.

[0053] The large diameter end of the funnel block 36 is matched with the inner diameter of the air outlet pipe 15.

[0054] The large diameter end of the cone-shaped block 38 is matched with the diameter of the outer pipe of the exhaust pipe 15.

[0055] The funnel block 36 and the cone block 38 scrape off the substances adsorbed on the inner wall of the outlet pipe 15 during their reciprocating motion.

[0056] The electrically controlled telescopic rod 33 and the metal plate 35 are magnetically attracted to each other.

[0057] The arc surface of the second contact block 211 is twice the size of the first contact block 27, and the four second contact blocks 211 and the first contact block 27 are combined to form a circular surface.

[0058] The first contact block 27 and the second contact block 211 are used together to engage and fix the connecting cavity 13.

[0059] The air supply hose 14 is fixedly connected to the air outlet pipe 15 and placed inside the pipe groove 22.

[0060] The working principle of all the content in the above embodiments is as follows:

[0061] In the initial state: the first abutment block 27 is placed at the front end of the first slide body 25, the second abutment block 211 is placed at the front end of the second slide body 29, and the first connecting rod 26 and the second connecting rod 210 are respectively inclined towards the first positioning ring 24 and the second positioning ring 28.

[0062] The following is the working process of the first component:

[0063] During use, the air supply hose 14 and the air outlet pipe 15 are connected to continuously deliver the regulated airflow to the fermentation chamber inside the tea fermentation machine 11 to maintain a suitable environment for tea fermentation. Since the requirements for airflow parameters are different at each stage of fermentation, the airflow control system changes the pressure and flow of the airflow in real time through the frequency adjustment of the fan connected to the air supply hose 14. During this process, the dynamic change of airflow pressure will generate a continuous impact load on the connection parts of the air supply hose 14, the air outlet pipe 15 and the device wall 12.

[0064] When the air supply hose 14 and the air outlet hose 15 are fixedly connected in the pipe groove 22, the external controller controls the external telescopic device of the first positioning ring 24 to start, pushing the first positioning ring 24 towards the pipe groove 22. At this time, the four first sliding groove bodies 25 slide in the fan-shaped groove 23 respectively, pushing the first abutment block 27 towards the pipe groove 22 until the front end of the first abutment block 27 first abuts against the inner wall surface of one side of the annular groove of the positioning housing 21. Under the abutting force of the positioning housing 21 on the first abutment block 27, the first abutment block 27 is initially limited, and the external telescopic device holds the first positioning ring 24 and the first sliding groove body 25. As the first slide body 25 continues to move, the forward movement of the first slide body 25 causes one end of the first connecting rod 26 rotatably connected to it to move synchronously. In the combination of the restriction of the first abutment block 27 by the positioning housing 21 and the thrust given to one end of the first connecting rod 26 by the first slide body 25, the end of the first slide body 25 away from the first positioning ring 24 abuts against the inner wall of the positioning housing 21. At this time, the first connecting rod 26 deflects in the positive direction with the end connected to the first slide body 25 as the axis, thereby pushing the first abutment block 27 to move towards the outer ring of the positioning housing 21, improving its tightness of engagement with the inner wall of the connecting cavity 13 opened in the device wall 12.

[0065] When the airflow pressure increases instantaneously, the wind speed sensor 31 detects the airflow pressure value and transmits the data to an external controller. Under the control of the controller, the drive device of the second positioning ring 28 is activated, causing it to move towards the pipe groove 22. Based on this, the second sliding groove 29 slides within the fan-shaped groove 23, coordinating with the second connecting rod 210 and the second abutment block 211 to move towards the pipe groove 22 until the front arc surface of the second abutment block 211 contacts the inner wall of the annular groove of the positioning housing 21, thus initially defining the position. The second connecting rod 210 continues to move towards the tube 22 until the second sliding groove 29 comes into contact with the inner wall of the positioning housing 21. Under the cooperation of the interaction forces, the second connecting rod 210 deflects in the positive direction with the connection point of the second sliding groove 29 as the axis. During this deflection process, the connection end of the second connecting rod 210 and the second contact block 211 is pushed to move gradually towards the outer ring of the positioning housing 21, strengthening the fit with the inner wall of the connecting cavity 13. This avoids the exchange strain force weakening the fastening performance of the connection structure during the increase or decrease of airflow pressure.

[0066] By setting the first component, the annular groove structure opened on the positioning housing 21 provides a limiting reference for the first abutment block 27 and the second abutment block 211, so that the movement and deflection of the first abutment block 27 and the second abutment block 211 always revolve around the axis of the positioning housing 21, ensuring that the connection part is subjected to uniform force and avoiding local wear caused by offset. This provides a foundation for the stable connection between the air supply hose 14, the air outlet pipe 15 and the device wall 12 under the impact of multi-stage airflow. In addition, the fitting design of the front arc surface of the first abutment block 27 and the second abutment block 211 with the inner wall of the annular groove of the positioning housing 21 can disperse the contact stress and avoid local wear. The movement into the connection cavity 13 can fill the connection gap and offset the deformation caused by the impact of airflow pressure. This is applicable to the alternating strain environment during multi-stage airflow switching.

[0067] By using the first component in conjunction with the airflow intensity, airflow leakage caused by loose connection between the air supply hose 14, the air outlet pipe 15 and the tea fermentation machine 11 is avoided. Combined with the feedback of airflow intensity from the wind speed sensor 31, the stronger the airflow, the tighter the air supply hose 14 and the air outlet pipe 15 are to the tea fermentation machine 11. This design ensures that the airflow parameters at each stage are transmitted stably according to the preset program, providing a precise and controllable environment for tea processing. It avoids the problem that traditional fastening methods are prone to fatigue failure under long-term alternating airflow pressure, which can lead to loosening of the air outlet pipe 15, resulting in equipment vibration, abnormal noise, or even component collision. Moreover, dynamic fastening can be achieved without manual intervention, adapting to the airflow characteristics of the entire tea processing process: the low-pressure airflow in the early stage of fermentation triggers basic fastening, avoiding stress accumulation in components due to excessive tightening; the high-pressure airflow in the roasting stage automatically enhances the fastening strength to cope with extreme working conditions.

[0068] Please refer to the above work process. Figures 1 to 7 .

[0069] The following is the working process of the second component:

[0070] In use, the electrically controlled telescopic rod 33 initiates the telescopic process. As the telescopic rod 33 extends and pushes the magnetic ring 34 to move, the magnetic ring 34 moves synchronously within the air outlet pipe 15 due to the magnetic attraction between the magnetic ring 34 and the metal plate 35. Through the connection between the metal plate 35 and components such as the funnel block 36, the funnel block 36 moves synchronously towards the outer end of the air outlet pipe 15. During this movement, the two guide posts symmetrically arranged on the outer ring of the guide body 37 slide within the arc-shaped groove 39. Furthermore, since the funnel block 36, the guide body 37, and the conical block 38 are all fixedly connected... As a whole, with the cooperation of the arc groove 39 and the guide post on the guide body 37, when the guide body 37 moves forward and rotates along the arc of the arc groove 39, the guide body 37 simultaneously coordinates with the funnel block 36 and the cone block 38 to rotate and move forward in the air outlet pipe 15. Under the action of matching the inner diameter of the air outlet pipe 15 and the outer pipe at one end of the funnel block 36 and the cone block 38, during the rotation and forward movement of the funnel block 36 and the cone block 38, the cone block 38 moves to the outside of the air outlet pipe 15 to scrape off the dust and debris such as tea impurities attached to the inner wall of the air outlet pipe 15, so as to prevent them from adhering to the inner wall of the air outlet pipe 15.

[0071] By using the magnetic ring 34 and the metal plate 35 in the second component, non-contact power transmission is achieved through magnetic attraction. The metal plate 35 can be moved synchronously without the need for a mechanical hard connection, reducing friction and wear between components. This is especially suitable for environments with a lot of dust in tea processing, reducing the risk of jamming caused by mechanical contact. At the same time, it simplifies the internal structure of the air outlet pipe 15 and avoids the obstruction of airflow by complex transmission components.

[0072] By adapting the shape of the funnel block 36 to the inner diameter of the air outlet pipe 15, it can scrape and guide the accumulated material on the inner wall of the pipe during the rotation and forward movement, and gather the debris towards the pipe opening. At the same time, its funnel-shaped structure can reduce the resistance to airflow and ensure the pressure stability during multi-stage airflow control. The sliding of the guide post on the guide body 37 in the arc groove 39 causes the guide body 37 to drive the entire structure to rotate and move forward along the arc path. This increases the contact area between the funnel block 36, the cone block 38 and the inner wall of the pipe and the spiral friction path. The rotation action also enhances the peeling effect on stubborn dust and avoids obstruction of airflow during the processing.
