Description

Technical Field

[0001] This invention belongs to the field of tea processing machinery technology, specifically relating to a digital automatic processing equipment for granular green tea. Background Technology

[0002] Granular green tea holds an important position in the tea market due to its unique appearance and quality characteristics. During processing, the leaves undergo shaping and solidification processes as moisture gradually evaporates during the stir-frying process, ultimately forming granules. Traditional processing methods rely heavily on manual labor, resulting in high labor intensity, low production efficiency, and inconsistent quality. However, using a tea-frying machine to form granular tea allows for a different process. The shape of the leaves depends on the machine's control over their movement and the force applied during stir-frying. Specifically, as the leaves fall after being lifted, they contact the pan wall and roll along it. The machine helps the unfolded leaves clump together, and as moisture evaporates, the tightness of this clump increases, ultimately forming uniform granules.

[0003] However, the existing tea frying machines have a relatively simple structural design and frying method, which cannot meet the forming process requirements of granular tea. Although they have improved production efficiency to some extent, they still have many technical defects: the starting angle of the wok rack in the tea frying machine is fixed and cannot be adjusted, which makes it impossible to adjust the height and movement of the tea leaves; in addition, most existing tea frying machines use a fixed wok body with a fixed baffle structure on the upper edge of the fixed wok body. After the tea is fried, manual unloading is required. The lack of digital control means leads to insufficient precision of processing parameters, and the poor stability of the mechanical structure affects the reliability of the equipment. Furthermore, accidental activation of the equipment switch can lead to safety hazards during manual unloading.

[0004] These problems severely restrict the improvement of quality and efficiency in the processing of granular green tea. In particular, in the tea-frying process, how to achieve uniform heating of tea leaves, precise control of processing parameters, and ensure the coordinated operation of various equipment components have become urgent technical challenges that need to be solved.

[0005] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0023] Due to the adoption of the above technical solution, the beneficial effects achieved by this invention are as follows:

[0024] 1. This solution eliminates the risk of mechanical interference through the automatic separation of the movable enclosure. The problem of the non-adjustable tea-tumbling angle in semi-automatic equipment is solved in this solution through an adjustable linkage mechanism in conjunction with a phase sensor. The wok wobbling problem caused by the existing single-bearing seat support is improved in this solution through a symmetrically arranged double-bearing seat structure, enhancing the turning stability. This application achieves automatic coordination between the enclosure and the wok's movements, avoiding efficiency losses caused by manual disassembly. The dynamic adjustment function of the tea-tumbling angle allows the tea leaves to achieve appropriate turning amplitude at different processing stages, ensuring processing stability while improving output efficiency and reducing tea leaf loss.

[0025] 2. This solution achieves precise parameter setting and automatic adjustment through a digital control system, avoiding human error; it also enables real-time monitoring of operating status through an integrated data acquisition unit, allowing for rapid identification of abnormal equipment conditions and reducing the risk of processing interruptions. This application achieves precise control of tea-frying temperature and time, ensuring stable heat treatment effects in the leaf curling and drying processes; it improves the uniformity of tea leaf turning and output efficiency through programmed control of the tea-turning angle and the timing of the baffle action; and it reduces the risk of tea loss due to equipment failure through a real-time data acquisition and feedback mechanism.

[0026] 3. This solution, through the integration of a data acquisition unit, can dynamically track the operational data of each mechanism, provide early warnings before malfunctions occur, improve the homogeneity of the finished tea granules, and achieve continuous monitoring of key equipment operating parameters. For example, during the tea-frying process, it can acquire real-time data on pan temperature fluctuations, tea-turning angle deviations, and the position of the retaining walls, ensuring that processing parameters remain within a controllable range. When the data acquisition unit detects an anomaly, the collected historical data can be used to optimize the processing technology, such as adjusting the heating strategy based on the temperature curve, thereby improving processing efficiency and product consistency.

[0027] 4. This application solves the problem of tea leaf spillage caused by insufficient stability during the wok flipping process, avoids tea leaf scorching caused by temperature fluctuations, and improves processing efficiency through automated workstation switching. The real-time monitoring function of the temperature sensor can promptly detect abnormalities in the heating unit, preventing the entire batch of tea from being scrapped due to equipment failure. The symmetrical bearing housing and fixed shaft structure reduce mechanical wear and extend the service life of the equipment.

[0028] 5. This application solves the problem of unstable swing trajectory caused by the asymmetrical support structure of traditional wok racks, effectively improving the uniformity of tea leaf turning. The rigid connection design between the arc-shaped stir-fry plate and the rotating shaft ensures the synchronization of tea leaf turning actions and avoids localized tea leaf accumulation caused by loose parts. The single-end connection between the drive mechanism and the rotating shaft simplifies the transmission path, reducing equipment complexity while ensuring power transmission efficiency, and facilitating quick maintenance by maintenance personnel. This structural design can also be adapted to wok mechanisms of different sizes. The equipment can be expanded by adjusting the length of the rotating shaft and the curvature of the arc-shaped stir-fry plate, enhancing the versatility of the processing equipment.

[0029] 6. This application solves the problems of rapid wear and frequent maintenance caused by rigid transmission in traditional tea-turning drive mechanisms, reducing the equipment failure rate. The combination of chain drive and eccentric wheel structure achieves decoupled control of tea-turning frequency and oscillation amplitude, allowing operators to dynamically adjust the tea-turning action parameters according to the moisture content of the tea leaves, avoiding the problems of tea scattering in the early stage of leaf curling or insufficient turning in the later stage of drying. The buffering effect of the connecting rod assembly effectively reduces mechanical impact and extends the service life of transmission components.

[0030] 7. This solution reduces motion friction through the rotating connection design of the ring sleeve and eccentric wheel, optimizes the swing trajectory by using a combination of an arc-shaped swing arm and an eccentric connecting shaft, and effectively solves the technical problems of large fluctuations in the tea-turning angle and low control precision by combining the real-time monitoring function of the angle sensor. Through the above technical solutions, this application achieves precise control and real-time feedback of the pot rack swing angle, ensuring dynamic adaptation of the tea-turning amplitude at different processing stages and avoiding uneven heating or mechanical jamming problems caused by angle deviations. The introduction of the angle sensor enables the control system to quickly identify abnormal swing states and adjust the drive parameters in a timely manner, significantly improving the stability of equipment operation and processing consistency.

[0031] 8. This solution, through the cooperation of the guide rail and drive components, achieves continuous adjustment of the starting angle of the tea-tumbling plate's swing. This application solves the problem of uneven heating of tea caused by the fixed tea-tumbling angle in existing equipment. By dynamically adjusting the tea-tumbling amplitude, it adapts to the needs of different processing stages and avoids tea clumping in the later stages of tea frying. The coordinated control of the phase sensor and drive components improves the automation level of angle adjustment, reduces the need for manual intervention, and ensures the consistency and stability of the processing process.

[0032] 9. This solution uses a barrier control motor to automatically raise and lower the barrier frame, completing the barrier separation action before the pot body flips, without manual intervention. The position sensor enables closed-loop detection of the barrier's position status, ensuring precise timing matching between the barrier separation action and the pot flipping. This application solves the problem of mechanical interference between the barrier and the pot body during pot flipping, ensuring that tea leaves do not spill during the tea leaf curling and forming process while also achieving automated discharge from the granular tea frying machine. The automatic lifting action of the barrier components and the pot frame flipping form a coordinated control, shortening the workstation switching time and improving discharge efficiency. The dual detection mechanism of the position sensor ensures the reliability of the barrier workstation switching, preventing equipment jamming due to incomplete barrier separation.

[0033] 10. This solution achieves automatic coordination of workstation switching while ensuring the functionality of the enclosure through the dynamic cooperation between the side panels and the enclosure components. In existing technologies, gaps exist between the enclosure and the sides of the pot, causing tea leaves to spill from both sides. This solution fundamentally solves this problem through the edge-abutment structure between the side panels and the enclosure components. This application effectively prevents tea leaves from spilling from both sides of the pot during stir-frying and unloading, reducing processing loss. The automatic coordination between the enclosure structure and the pot workstation switching avoids manual intervention and improves production efficiency. Attached Figure Description

[0044] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

[0049] In existing technologies, the processing of granular green tea suffers from problems such as poor uniformity of tea turning and insufficient coordination between the tea rack and the wok. Traditional equipment uses a fixed rack assembly structure, requiring manual disassembly of the rack when the wok is turned over to discharge the tea, resulting in cumbersome operation and easy spillage of tea leaves. In semi-automatic equipment, the angle of the wok frame is fixed and cannot be dynamically adjusted according to the processing stage, causing uneven heating of the tea leaves. In addition, the insufficient stability of the wok support structure causes shaking during turning, affecting the accuracy of discharge.

[0050] To address the aforementioned issues, a device is needed that can automatically coordinate the movements of the guardrail and the wok, and dynamically adjust the tea-tumbling angle. Considering the varying requirements for turning amplitude at different processing stages, a wok frame with controllable swing range needs to be constructed. To address the interference between the guardrail and the wok, a detachable guardrail component needs to be developed to provide movement space. Simultaneously, the stability of the supporting structure needs to be strengthened to ensure the reliable operation of the equipment.

[0051] Therefore, refer to Figures 1-7 This application proposes a digital automatic processing equipment for granular green tea, including a frame-type support 1 and a wok mechanism. The wok mechanism is rotatably connected to the frame-type support 1 so that the wok mechanism has a tea-frying station for completing the tea-frying process and a discharge station for pouring out the processed tea leaves. The wok mechanism has a concave wok body 21; a wok rack, rotatably connected to the frame-type support 1, and an arc-shaped frying plate 31 that cooperates with the inner cavity of the wok body 21; a drive mechanism for driving the arc-shaped frying plate 31 to reciprocate within the wok body 21; a phase adjustment mechanism for controlling the reciprocating sway angle of the arc-shaped frying plate 31; and a containment mechanism, including a movable containment component rotatably connected to the frame-type support 1 and a fixed containment component fixed to the discharge side of the wok mechanism. Before the wok mechanism switches from the tea-frying station to the discharge station, the movable containment component rotates and separates from the fixed containment component, providing movement space for the wok mechanism to switch stations.

[0052] The frame-type support unit 1 is the main structure supporting all components of the equipment. It can be constructed using a combination of a metal frame and transverse reinforcing beams, and its function is to provide stable support for the rotation of the wok. The wok mechanism includes a concave wok body 21 and rotating connecting parts. It achieves 50-90 degree rotation through the cooperation of a bearing seat and a fixed shaft 201, used to switch between processing and discharging states. The arc-shaped wok plate 31 is a metal plate that matches the inner curved surface of the wok body 21. It is driven by a rotating shaft 3 to achieve reciprocating oscillation. Its arc design can reduce tea leaf breakage. The drive mechanism includes a motor and transmission components. It converts the rotational motion into the oscillating motion of the flipping plate through a gear chain 35 and a linkage mechanism. The phase adjustment mechanism includes an angle sensor and a controller. It controls the oscillation amplitude of the flipping plate by adjusting the motor stroke. The movable enclosure assembly includes a rotatable support shaft 6 and enclosure parts 63. Before the wok is rotated, it is separated from the fixed enclosure by a motor drive to avoid mechanical interference.

[0053] Specifically, during the tea-frying stage, the wok is in a horizontal position, and the baffle assembly closes to form a continuous guard. The drive mechanism drives the arc-shaped frying plate 31 to swing at a set angle, ensuring the tea leaves are heated evenly. When processing is complete, the controller activates the baffle motor, causing the movable baffle to rotate outward to the separation position. Subsequently, the wok drive motor operates, causing the wok body 21 to flip to the discharge position, and the tea leaves slide out along the inclined wok surface. During this process, the baffle separation action and the wok flipping action are synchronized, requiring no manual intervention. The swing angle of the wok frame can be adjusted by the controller according to the moisture content of the tea leaves; initially, a small angle of swing is used to prevent spillage, and later the angle is increased to promote particle formation.

[0054] Compared to existing technologies, traditional equipment requires manual disassembly of fixed barriers. This solution eliminates the risk of mechanical interference by automatically separating movable barriers. The issue of the non-adjustable tea-tumbling angle in semi-automatic equipment is resolved in this solution through an adjustable linkage mechanism in conjunction with a phase sensor.

[0055] Through the above technical solution, this application achieves automatic coordination between the enclosure and the wok, avoiding efficiency losses caused by manual disassembly. The dynamic adjustment function of the tea-turning angle allows the tea leaves to receive appropriate turning amplitude at different processing stages, improving heating uniformity. The movable enclosure combined with the double-bearing support structure ensures processing stability while improving output efficiency and reducing tea leaf loss.

[0056] This application further proposes a control system, which includes an instruction input terminal, a controller, and a data acquisition unit. The controller is used to control the heating temperature and heating time of the wok mechanism; the controller is used to control the operation or stop of the drive mechanism; the controller is used to control the phase adjustment mechanism to adjust the swing angle of the arc-shaped wok plate 31; and the controller is used to control the movable enclosure component to separate from the wok mechanism before the wok mechanism switches from the tea frying station to the discharge station.

[0057] The instruction input terminal is the interface for receiving operation instructions, which can be implemented using a touch screen or physical buttons. It is used to set the heating temperature range, processing time parameters, tea-tumbling angle parameters, and to display the operating status of each mechanism. The controller is the control unit that performs logic operations, which can be implemented using a PLC or embedded microprocessor. It generates corresponding control signals based on the parameter settings received from the instruction input terminal to adjust the power of the heating unit 23, the speed of the drive motor, and the timing of the enclosure mechanism's actions. The data acquisition unit is a sensor component that collects equipment operating data, which can be implemented using temperature sensors, angle sensors, and position sensors. It is used to acquire real-time data on the pot body 21 temperature, the tilting plate swing angle, and the enclosure position status.

[0058] Specifically, the control system receives the temperature threshold, processing time, and tea-turning angle parameters set by the operator through the command input terminal. The controller generates corresponding control commands according to the preset program. During the tea-frying stage, the controller sends a temperature adjustment signal to the heating unit 23 to maintain the temperature of the pot 21 within the set range; simultaneously, the controller sends start / stop commands to the drive mechanism to make the pot frame oscillate at a set frequency. When it is necessary to switch to the discharge station, the controller sends a separation command to the enclosure mechanism to prematurely release it from contact with the pot 21. The data acquisition unit collects the operating data of each actuator in real time and feeds it back to the controller, forming a closed-loop control circuit to ensure stable execution of processing parameters.

[0059] Compared to existing technologies, traditional semi-automatic equipment relies on manual experience to adjust heating power and tea-turning frequency, resulting in large parameter fluctuations and slow response. This solution achieves precise parameter setting and automatic adjustment through a digital control system, avoiding human error; and integrates a data acquisition unit for real-time monitoring of operating status, enabling rapid identification of abnormal equipment conditions and reducing the risk of processing interruptions.

[0060] Through the above technical solutions, this application achieves precise control of tea frying temperature and time, ensuring stable heat treatment effect during the rolling and shaping process of tea frying; improves the uniformity of tea turning and discharge efficiency by programmatically controlling the tea turning angle and the timing of the surrounding action; and reduces the risk of tea loss due to equipment failure through real-time data acquisition and feedback mechanisms.

[0061] This application further proposes a data acquisition unit for collecting data on the operation of the wok mechanism, drive mechanism, phase adjustment mechanism, and movable enclosure component, so as to monitor the operating status of any of these mechanisms in real time.

[0062] The data acquisition unit is a device used to collect operating parameters of various components of the equipment. Specifically, it can employ temperature sensors, angle sensors, and position sensors. For example, a temperature sensor is installed on the surface of the pot body 21 to monitor the heating temperature, an angle sensor is installed at the end of the rotating shaft 3 to detect the swing angle of the pot frame, and a position sensor is installed near the enclosure assembly to confirm its working status. These sensors feed real-time data back to the control system, facilitating timely detection of operational anomalies.

[0063] Specifically, the data acquisition unit continuously collects data on the temperature of the wok mechanism, the operating frequency of the drive mechanism, the adjustment range of the phase adjustment mechanism, and the position signals of the enclosure components through a sensor network distributed at key locations on the equipment. For example, when the temperature of the wok body 21 deviates from the set range, the temperature sensor transmits a signal to the controller, triggering the temperature compensation mechanism; when the swing angle of the wok frame exceeds a preset threshold, the angle sensor sends an alarm signal to the operating interface, prompting maintenance; when the enclosure components fail to reach the designated workstation within a predetermined time, the position sensor generates a fault code, suspending equipment operation to avoid mechanical interference. Thus, the operating status of each mechanism is monitored in real time, ensuring the stability of the processing flow.

[0064] Compared to existing technologies, current semi-automatic equipment lacks real-time acquisition and feedback of operating parameters. For example, it cannot monitor whether the pot rack is stuck or whether the heating unit 23 is malfunctioning, making it difficult to detect processing abnormalities in a timely manner. This solution, however, integrates a data acquisition unit to dynamically track and monitor the operating data of each mechanism. For example, it uses an angle sensor to capture changes in the swing amplitude of the pot rack, identify wear on connecting rods or abnormal load on the drive motor, and thus provide early warnings before malfunctions occur, avoiding problems such as burnt edges or clumping of tea leaves due to uneven turning.

[0065] Through the above technical solution, this application achieves continuous monitoring of key operating parameters of the equipment, such as real-time acquisition of temperature fluctuations in the pot 21, tea-turning angle deviations, and the position status of the baffle during the tea-frying process, ensuring that processing parameters are always within a controllable range. Simultaneously, the collected historical data can be used to optimize the processing technology, such as adjusting the heating strategy based on the temperature curve to improve processing efficiency and product consistency.

[0066] Reference Figures 1-3 This application further proposes a digital automatic processing equipment for granular green tea, including a wok mechanism. The wok mechanism includes a wok frame 2 for fixing the wok body 21. The bottom of the wok body 21 has a heating unit 23 arranged in sections. The data acquisition unit includes a temperature sensor installed on the surface of the wok body 21. The frame support part 1 has first bearing seats 22 symmetrically arranged on both sides for supporting the wok frame 2. The wok frame 2 has fixed shafts 201 fixedly connected to both sides. The fixed shafts 201 are connected to the bearing seats. The bottom of the wok frame 2 has a semi-circular plate 24. The edge of the semi-circular plate 24 has drive teeth 241. The frame support part 1 is fixedly connected to a wok control motor 25.

The wok control motor 25 is electrically connected to a controller so that the controller controls the wok frame 2 to switch between the tea frying station and the discharge station through the wok control motor 25.

[0067] The pot frame 2 is a supporting structure for fixing the pot body 21. It can be formed by welding a metal frame and provides stable support for the pot body 21, transmitting the driving force for turning. The heating unit 23 is a device for heating the pot body 21, specifically using an electric heating tube or an electromagnetic heating coil. Its function is to achieve the curling and drying of tea leaves through precise temperature control. Each heating unit 23 in the zoned heating units is independently controlled. Users can independently set the heating units 23 of each zone according to process requirements, ensuring consistent temperatures or customized differences between zones to adapt to different processing techniques. The temperature sensor is an element used to detect the surface temperature of the pot body 21, specifically using a thermocouple or an infrared temperature measurement module. Its function is to feed back real-time temperature data to the control system to adjust the heating power. The first bearing seat 22 is a bearing assembly symmetrically installed on both sides of the frame-type support part 1. It can be a rolling bearing or a sliding bearing, and its function is to support the pot frame 2 by fixing the shaft 201 and reducing rotational friction resistance. The semi-circular plate 24 is an arc-shaped structure fixed to the bottom of the pot frame 2. It can be made of steel plate and its function is to transmit torque through the meshing of the drive gear 241 and the first drive gear 251. The first drive gear 251 is a gear connected to the output end of the wok control motor 25. It can be a helical gear or a spur gear. Its function is to convert the rotational motion of the motor into the flipping motion of the pot frame 2. The rotation angle of the pot frame 2 is 50-90°, which is the flipping range of the wok between the tea frying station and the discharge station. It can be controlled by limit switches or encoders to realize the automated switching between tea processing and pouring.

[0068] Specifically, after the pot body 21 is fixed by the pot support 2, the fixed shafts 201 on both sides are embedded in the first bearing seat 22 to form a stable support, preventing axial displacement when the wok is flipped. The drive teeth 241 at the bottom of the semi-circular plate 24 mesh with the first active gear 251. When the wok control motor 25 is started, the gear transmission drives the pot support 2 to rotate around the fixed shaft 201, allowing the pot body 21 to switch positions within the range of 50-90°. The temperature sensor collects the surface temperature data of the pot body 21 in real time and transmits it to the controller. The controller adjusts the power of the heating unit 23 according to the preset program to ensure stable processing temperature. When it is time to discharge, the controller drives the wok control motor 25 to reverse, and the pot support 2 tilts the pot body 21 to the discharge position, where the tea leaves slide out automatically under gravity.

[0069] Compared to existing technologies, traditional equipment using a single-sided bearing seat causes the pot body 21 to wobble, while the symmetrically arranged first bearing seat 22, in conjunction with the fixed shaft 201, significantly improves structural stability. Existing equipment relies on manual observation to judge the pot temperature, while the closed-loop control of the temperature sensor and heating unit 23 achieves precise temperature regulation. Semi-automatic equipment requires manual operation to flip the pot body 21, while the wok control motor 25 and gear transmission mechanism enable automatic switching of work positions, reducing manual intervention.

[0070] Through the above technical solutions, this application solves the problem of tea spillage caused by insufficient stability during the wok flipping process, avoids tea scorching caused by temperature fluctuations, and improves processing efficiency through automated station switching. The real-time monitoring function of the temperature sensor can promptly detect abnormalities in the heating unit 23, preventing the entire batch of tea from being scrapped due to equipment failure. The symmetrical bearing seat and fixed shaft 201 structure reduces mechanical wear and extends the service life of the equipment.

[0071] Reference Figures 1-3 as well as Figure 6 and Figure 7 This application further proposes that the pot rack includes second bearing seats 32 symmetrically arranged on both sides of the frame support part 1, a rotating shaft 3 is fixedly connected between the two second bearing seats 32, the arc-shaped stir-fry plate 31 is fixedly connected to the rotating shaft 3, and the driving mechanism is connected to one end of the rotating shaft 3 to drive the rotating shaft 3 to rotate back and forth.

[0072] The second bearing seat 32 is a symmetrically arranged support structure on both sides of the frame. It can be implemented using a metal seat with rolling bearings to support the rotating shaft 3 and ensure its rotational stability. The rotating shaft 3 is a rigid shaft that runs laterally through the two second bearing seats 32. It can be implemented using a hollow stainless steel tube to transmit driving force and drive the arc-shaped stir-fry plate 31 to swing synchronously. The arc-shaped stir-fry plate 31 is a curved structure fixedly connected to the rotating shaft 3. It can be implemented using a stamped arc-shaped metal plate, and its curvature matches the inner contour of the pot body 21 to improve the tea-stirring coverage. The drive mechanism is connected to the rotating shaft 3 by transmitting power to the rotating shaft 3 through a mechanical transmission component. This can be implemented using a combination structure of an eccentric wheel 342 and a connecting rod, converting rotational motion into reciprocating oscillation.

[0073] Specifically, the symmetrically arranged second bearing seats 32 provide double-sided support for the rotating shaft 3, effectively reducing radial runout during operation and ensuring the stability of the swing trajectory of the arc-shaped stir-fry plate 31. The rotating shaft 3 passes through the two bearing seats and is rigidly connected to the arc-shaped stir-fry plate 31, allowing the power output from the drive mechanism to be evenly transmitted to the entire flip plate. The drive mechanism drives the rotating shaft 3 to rotate in both directions, causing the arc-shaped stir-fry plate 31 to swing periodically within the inner cavity of the pot body 21. During the swing, the edge of the flip plate maintains a clearance fit with the inner wall of the pot body 21, achieving sufficient turning of the tea leaves while avoiding frictional wear with the pot body 21. The swing amplitude of the arc-shaped stir-fry plate 31 is determined by the stroke of the drive mechanism, and its reciprocating motion trajectory covers the area from the bottom to the side wall of the pot body 21, ensuring that the tea leaves at different processing stages are evenly turned.

[0074] Compared to existing technologies, traditional pot supports often employ a single-sided supported shaft 3 structure, which is prone to misalignment due to uneven force distribution, leading to jamming of the flip plate or deviation in the swing angle. This solution, through a combination of symmetrical bearing seats on both sides and a rigid shaft 3, significantly improves the operational stability of the shaft 3, resulting in more precise control of the flip plate's swing angle. Furthermore, existing tea-tumbling drives often rely on direct gear transmission, which suffers from reduced transmission efficiency due to gear wear. This solution, however, uses an eccentric wheel 342 and a connecting rod transmission method, reducing mechanical impact through a flexible connection and extending the service life of the drive mechanism.

[0075] Through the above technical solution, this application solves the problem of unstable swing trajectory caused by the asymmetrical support structure of traditional wok racks, effectively improving the uniformity of tea leaf turning. The rigid connection design between the arc-shaped frying plate 31 and the rotating shaft 3 ensures the synchronization of tea leaf turning actions and avoids local accumulation of tea leaves due to loose parts. The single-end connection between the drive mechanism and the rotating shaft 3 simplifies the transmission path, reduces equipment complexity while ensuring power transmission efficiency, and facilitates quick maintenance by maintenance personnel. This structural design can also be adapted to frying wok mechanisms of different sizes. By adjusting the length of the rotating shaft 3 and the curvature of the arc-shaped frying plate 31, the equipment can be expanded, enhancing the versatility of the processing equipment.

[0076] Reference Figures 1-5 This application further proposes a drive mechanism including a stir-fry control motor 33 fixed on a frame support 1 and a transmission shaft 34 rotatably connected to the frame support 1. The output end of the stir-fry control motor 33 is fixedly connected to a second drive gear 331. The end of the transmission shaft 34 is provided with a driven gear 341. A chain 35 is connected between the drive gear and the driven gear 341. An eccentric wheel 342 is fixedly connected to the transmission shaft 34. A connecting rod assembly is provided between one end of the rotating shaft 3 and the eccentric wheel 342. The rotation of the eccentric wheel 342 drives the rotating shaft 3 to rotate in both directions through the connecting rod assembly.

[0077] The stir-frying plate control motor 33 is the power output unit, which can be implemented using a servo motor or a stepper motor, to provide a controllable power source for the pot rack. The drive shaft 34 is the power transmission unit, which can be implemented using a steel shaft with bearing housings, to transmit the rotational power of the stir-frying plate control motor 33 to the eccentric wheel 342. The chain drive 35 is the power transmission method, which can be implemented using a roller chain 35 with sprockets, to isolate motor vibration and adapt to long-distance transmission requirements. The eccentric wheel 342 is the motion conversion unit, which can be implemented using a disc structure with an off-center shaft hole, to convert rotational motion into reciprocating oscillation. The connecting rod assembly is the motion transmission unit, which can be implemented using hinged metal rods, to convert the circular motion of the eccentric wheel 342 into the reciprocating oscillation of the rotating shaft 3.

[0078] Specifically, the stir-frying plate control motor 33 drives the chain 35 via the drive gear, which in turn drives the driven gear 341 on the transmission shaft 34 to rotate synchronously. The transmission shaft 34 drives the eccentric wheel 342 to rotate continuously, and the circular motion of the outer edge of the eccentric wheel 342 is converted into the reciprocating oscillation of the rotating shaft 3 through the connecting rod assembly. The rotating shaft 3 drives the arc-shaped stir-frying plate 31 to perform periodic tea-turning actions within the inner cavity of the pot body 21. The chain 35 transmission structure can effectively buffer the impact load when the motor starts and stops, and the cooperation between the eccentric wheel 342 and the connecting rod assembly allows for adjustable tea-turning oscillation angles. By controlling the speed of the stir-frying plate control motor 33, the tea-turning frequency can be precisely adjusted to adapt to the tea's condition at different processing stages.

[0079] Compared to existing technologies, traditional tea-tumbling drive mechanisms often employ direct gear meshing, which is prone to increased transmission clearance due to gear wear over long-term operation, leading to tea-tumbling angle deviation or mechanism jamming. This solution replaces direct gear connection with chain drive 35, utilizing the flexible transmission characteristics of chain 35 to reduce the risk of gear wear. Simultaneously, the combined structure of eccentric wheel 342 and connecting rod assembly replaces the traditional fixed-angle tea-tumbling drive method, allowing the tea-tumbling angle to be dynamically adjusted by regulating the phase of eccentric wheel 342 or the length of the connecting rod, significantly improving the equipment's adaptability to different processing stages.

[0080] Through the above technical solution, this application solves the problems of rapid wear and frequent maintenance caused by rigid transmission in traditional tea-turning drive mechanisms, thus reducing the equipment failure rate. The cooperation between the chain 35 transmission and the eccentric wheel 342 structure achieves decoupled control of the tea-turning frequency and swing amplitude, allowing operators to dynamically adjust the tea-turning action parameters according to the moisture content of the tea leaves, avoiding the problems of tea scattering in the early stage of leaf curling or insufficient turning in the later stage of drying. The buffering effect of the connecting rod assembly effectively reduces mechanical impact and extends the service life of the transmission components.

[0081] Reference Figures 1-7 This application further proposes a linkage mechanism including a linkage seat 4 mounted on a frame-type support 1. A vertically arranged vertical link 41 is rotatably connected to the linkage seat 4. A horizontal link 42 is hinged to the side wall of the vertical link 41. A ring 421 is provided at the end of the horizontal link 42 away from the vertical link 41. The ring 421 is fitted on the outer wall of the eccentric wheel 342 and rotatably connected to the outer wall of the eccentric wheel 342. An arc-shaped swing arm 43 is hinged to the upper end of the vertical link 41. An eccentrically arranged connecting shaft 301 is fixedly connected to the end of the rotating shaft 3 near the arc-shaped swing arm 43. The end of the arc-shaped swing arm 43 away from the vertical link 41 is hinged to the connecting shaft 301. The data acquisition unit includes an angle sensor for detecting the rotation angle of the connecting shaft 301.

[0082] The connecting rod seat 4 is a support structure that supports the vertical connecting rod 41. It can be made of cast iron and has internal rolling bearings to achieve rotational connection of the vertical connecting rod 41. This structure can stably transmit the reciprocating driving force generated by the eccentric wheel 342. The vertical connecting rod 41 is a power transmission rod arranged in the vertical direction. It can be made of hollow steel tubing, and its sidewall is hinged to the horizontal connecting rod 42 to avoid motion interference. The horizontal connecting rod 42 is a transverse rod connecting the vertical connecting rod 41 and the eccentric wheel 342. It can be made of aluminum alloy profile. One end is connected to the vertical connecting rod 41 via a hinge, and the other end has a ring 421 structure. The ring 421 is an annular connector fitted onto the outer wall of the eccentric wheel 342. It can be made of nylon, and its inner wall has ball bearings to achieve rotational connection with the eccentric wheel 342. This structure can convert the rotational motion of the eccentric wheel 342 into the reciprocating oscillation of the horizontal connecting rod 42. The arc-shaped swing arm 43 is a curved force-transmitting component connecting the vertical connecting rod 41 and the rotating shaft 3. It can be formed by bending stamped steel plate, and its arc trajectory can adapt to the eccentric swing path of the rotating shaft 3. The connecting shaft 301 is a transmission component fixed to and eccentrically positioned with the rotating shaft 3. It can be a stepped shaft structure, and its eccentricity design can adjust the swing amplitude of the flap. The angle sensor is a measuring device for detecting the rotation angle of the connecting shaft 301. It can be a photoelectric encoder or a potentiometer-type sensor, and its signal output is connected to the control system to achieve closed-loop control of the flap swing angle.

[0083] When the drive mechanism drives the eccentric wheel 342 to rotate, the ring 421 moves in a circular motion with the outer wall of the eccentric wheel 342, pushing the horizontal connecting rod 42 to move laterally and reciprocally. The movement of the horizontal connecting rod 42 is transmitted to the vertical connecting rod 41 through a hinge, causing it to swing up and down around the axis of the connecting rod seat 4. The arc-shaped swing arm 43 at the top of the vertical connecting rod 41 then generates an arc-shaped trajectory movement, driving the connecting shaft 301 to rotate eccentrically through the hinge point. Since the connecting shaft 301 is fixedly connected to the rotating shaft 3, the rotating shaft 3 achieves forward and reverse reciprocating rotation under the drive of the connecting shaft 301, thereby driving the arc-shaped stir-fry plate 31 to swing within the pot body 21. The angle sensor monitors the rotation angle of the connecting shaft 301 in real time and transmits the angle signal to the control system. When the actual swing angle deviates from the set range, the controller can dynamically adjust the operating parameters of the drive mechanism to correct the deviation.

[0084] Compared to existing technologies, traditional pot racks often use rigid connections in their linkage components and lack an angle feedback mechanism, resulting in uncontrollable tilting angles of the flipper and a tendency for uneven tea leaf turning or mechanical jamming. This solution reduces motion friction through the rotational connection design of the ring sleeve 421 and the eccentric wheel 342, optimizes the swing trajectory by using a combination of the arc-shaped swing arm 43 and the eccentric connecting shaft 301, and effectively solves the technical problems of large fluctuations in the tea-turning angle and low control precision by combining the real-time monitoring function of the angle sensor.

[0085] Through the above technical solution, this application achieves precise control and real-time feedback of the pot rack's swing angle, ensuring dynamic adaptation of the tea's turning amplitude at different processing stages and avoiding uneven heating or mechanical jamming caused by angle deviation. The introduction of the angle sensor enables the control system to quickly identify abnormal swing states and adjust drive parameters in a timely manner, significantly improving the stability of equipment operation and processing consistency.

[0086] Reference Figures 1-3 as well as Figure 7 This application further proposes a phase adjustment mechanism including a bushing 5 fixed on a frame support 1. The bushing 5 is internally threaded with a lead screw. The two ends of the lead screw are respectively provided with a connecting rod seat 4 and a driven pulley 511. The lower end of the vertical connecting rod 41 is hinged to the connecting rod seat 4. The frame support 1 is provided with a phase adjustment motor 53. The output end of the phase adjustment motor 53 is provided with a driving pulley 531. A belt 54 is connected between the driving pulley 531 and the driven pulley 511. The data acquisition unit includes two sets of phase sensors arranged at intervals along the guide rail. The positions of the two sets of phase sensors correspond to the minimum and maximum horizontal movement distances of the connecting rod seat 4, thereby limiting the minimum and maximum values ​​of the starting angle of the reciprocating swing of the rotating shaft 3.

[0087] In the drive assembly, bushing 5, in conjunction with the lead screw, converts rotary motion into linear motion via a threaded pair. Specifically, a ball screw or trapezoidal lead screw can be used. Its function is to precisely control the displacement of the connecting rod seat 4 through the rotation of the lead screw. The driven pulley 511 and the driving pulley 531 are connected by a belt 54 to transmit power via belt drive. Specifically, a synchronous belt or V-belt can be used. Its function is to transmit the rotational power of the phase-adjusting motor 53 to the lead screw. The phase sensor is a sensing element used to detect the position of the connecting rod seat 4. Specifically, a photoelectric sensor or proximity switch can be used. Its function is to limit the starting angle of the swing of the shaft 3 by detecting whether the connecting rod seat 4 has reached a preset position.

[0088] Specifically, when adjusting the starting angle of the swing of the arc-shaped frying plate 31, the phase adjustment motor 53 starts and drives the drive pulley 531 to rotate, which in turn drives the driven pulley 511 and the lead screw to rotate synchronously via the belt 54. The rotational motion of the lead screw is converted into the axial movement of the lead screw inside the bushing 5 through the threaded pair, which in turn drives the connecting rod seat 4 to move horizontally. When the connecting rod seat 4 moves to the end closest to the bushing 5, one of the phase sensors is triggered. At this time, the starting angle of the swing of the arc-shaped frying plate 31 reaches its minimum value. In this state, the reciprocating swing of the arc-shaped frying plate 31 can maximize the height to which the tea leaves in the pot are thrown, resulting in the smallest diameter of the processed tea particles. When the connecting rod seat 4 moves to the farthest end from the bushing 5, the other phase sensor is triggered. At this time, the starting angle of the swing of the arc-shaped frying plate 31 reaches its maximum value. In this state, the reciprocating swing of the arc-shaped frying plate 31 can maximize the height to which the tea leaves in the pot are thrown, resulting in the largest diameter of the processed tea particles. By controlling the forward and reverse rotation of the phase adjustment motor 53, the relative position of the lead screw and bushing 5 can be dynamically adjusted, thereby continuously changing the swing angle range of the arc-shaped frying plate 31 to adapt to the requirements of different processing stages for the starting angle of tea turning.

[0089] Compared to existing technologies, traditional semi-automatic tea-frying equipment uses a fixed initial angle for the reciprocating oscillation of the wok rack, making it impossible to adjust the initial angle of the oscillation according to the state of the tea leaves. This results in the production of tea leaves with only a single diameter, leading to a limited range of processed products. This solution, however, utilizes bushing 5 and a lead screw to achieve continuous adjustment of the initial oscillation angle of the tea-tumbling plate within a certain range. For example, a smaller tossing height is used during the drying stage to prevent tea leaves from spilling, while a larger tossing height is used during the shaping stage to promote particle formation. The phase sensor further ensures the accuracy and reliability of the oscillation angle adjustment, avoiding angle deviations caused by mechanical errors.

[0090] In addition, as a preferred embodiment of the phase adjustment mechanism, a rotation angle detection component is added to the outer end of the driven pulley 511 to detect the rotation angle of the driven pulley 511 and convert it into the displacement of the connecting rod seat 4. The controller then achieves precise adjustment of the initial angle of the arc-shaped wok plate 31's swing. The preferred configuration of the rotation angle detection component is as follows: a circular baffle is fixed to the driven pulley 511, and several hollow areas are evenly spaced on the outer circumference of the circular baffle. A beam of light from the beam of light emitted by the beam of light emitted by the beam of light is also included. During the synchronous rotation of the circular baffle and the driven pulley 511, the beam of light emitted by the beam of light is perpendicular to the circular baffle. Each time a hollow area passes through the beam of light emitted by the beam of light emitted by the beam of light, the beam of light receives a trigger signal. Each trigger signal means that the driven pulley 511 has rotated by one unit angle, for example, 10°, thereby achieving precise and automated control of the initial angle of the arc-shaped wok plate 31's swing.

[0091] Through the above technical solution, this application solves the problem of uneven heating of tea leaves caused by the fixed tea-tumbling angle in existing equipment. By dynamically adjusting the tea-tumbling amplitude, it adapts to the needs of different processing stages and avoids tea leaves clumping in the later stages of tea frying. The coordinated control of the phase sensor and drive components improves the automation level of angle adjustment, reduces the need for manual intervention, and ensures the consistency and stability of the processing.

[0092] Reference Figures 1-3 This application further proposes a fencing mechanism including third bearing seats 61 symmetrically arranged on both sides of the frame-type support 1, a support shaft 6 fixedly connected between the two sets of third bearing seats 61, a fencing frame 62 fixedly connected to the support shaft 6, a fencing component 63 cooperating with the upper edge of the pot body 21 fixedly connected to the end of the fencing frame 62 away from the support shaft 6, a first gear 64 provided at the end of the support shaft 6, a fencing control motor 65 fixedly connected to the frame-type support 1, a second gear meshing with the first gear 64 fixedly connected to the output end of the fencing control motor 65, a controller electrically connected to the fencing control motor 65 to control the rotation of the fencing frame 62, the fencing frame 62 rotating to have a first position where the fencing component 63 cooperates with the upper edge of the pot body 21, and a second position where the fencing component 63 separates from the upper edge of the pot body 21 and does not interfere with the rotation of the pot frame 2; it also includes two sets of position sensors, the positions of the two sets of position sensors corresponding to the first position and the second position of the fencing frame 62, respectively.

[0093] The third bearing seat 61 serves as a fixed base for mounting the support shaft 6. It can be implemented using a rolling bearing seat with a sealing structure, and its symmetrical arrangement ensures the stability of the support shaft 6 during rotation. The support shaft 6 is a rigid shaft passing through both sets of third bearing seats 61. It can be implemented using a chrome-plated alloy steel shaft and is used to bear the rotational torque of the enclosure frame 62. The enclosure frame 62 is a frame structure connecting the support shaft 6 and the enclosure component 63. It can be implemented using a stainless steel welded truss, and the enclosure component 63, located at the end furthest from the support shaft 6, can form a continuous closed structure with the upper edge of the pot body 21. The first gear 64 and the second gear form a reduction transmission pair, which can be implemented using a helical gear set with a module of 3. The enclosure frame 62 is switched between work positions by being driven by the enclosure control motor 65. The position sensor is a detection element used to detect the rotation angle of the enclosure frame 62. It can be implemented using a Hall sensor or a photoelectric sensor, with the two sets of sensors corresponding to the extreme positions of the first and second work positions, respectively.

[0094] Specifically, at the tea-frying station, the enclosure control motor 65 drives the support shaft 6 to rotate via gear transmission, causing the enclosure frame 62 to press down the enclosure component 63 to the upper edge of the pot body 21, forming a closed enclosure. When switching to the discharge station, the controller sends a command to start the enclosure control motor 65 to rotate in the reverse direction, and the enclosure frame 62 rises upward, separating the enclosure component 63 from the pot body 21. Two sets of position sensors detect the rotation angle of the enclosure frame 62 in real time. When the enclosure component 63 is detected to have reached the preset first or second station, a signal is sent to the controller to cut off the power to the enclosure control motor 65. During this process, the lifting path of the enclosure component 63 avoids the overturning trajectory of the pot frame 2, preventing mechanical interference.

[0095] Compared to existing technologies, most tea-frying machines use a fixed pot body with a fixed baffle structure on the upper edge. This requires manual unloading after frying, and the lack of digital control results in insufficient precision in processing parameters and poor mechanical stability, affecting equipment reliability. Furthermore, accidental activation of the machine's switches can pose safety hazards during manual unloading. This solution uses a motor-driven baffle frame 62 to automatically lift and lower, completing the baffle separation action before the pot body 21 flips, eliminating the need for manual intervention. Position sensors enable closed-loop detection of the baffle's position status, ensuring precise timing matching between the baffle separation action and the pot flipping.

[0096] Through the above technical solution, this application solves the problem of mechanical interference between the baffle and the pot body 21 when the wok is turned over. While ensuring that tea leaves do not spill during the rolling and shaping process, it also achieves automated discharge from the granular tea frying machine. The automatic lifting action of the baffle component 63 and the turning of the pot frame 2 form a coordinated control, shortening the station switching time and improving the discharge efficiency. The dual detection mechanism of the position sensor ensures the reliability of the baffle station switching and prevents equipment jamming caused by incomplete separation of the baffle.

[0097] Reference Figures 1-3 This application further proposes a digital automatic processing equipment for granular green tea. Side plates 7 are fixedly connected to both sides of the pot body 21. The two side plates 7 are located on both sides of the discharge direction of the pot body 21. When the enclosure frame 62 rotates from the second station to the first station, the two ends of the enclosure member 63 abut against the edges of the two side plates 7 to form a continuous enclosure structure.

[0098] The side plate 7 is a plate-like structure fixed to both sides of the pot body 21 in the discharge direction. It can be fixed to the outer wall of the pot body 21 by welding or bolting metal plates, and its height can be set to be flush with or slightly higher than the upper edge of the pot body 21. When the wok mechanism is in the discharge position, this structure can prevent tea leaves from spilling from both sides of the pot body 21, reducing tea leaf loss during the discharge process. The baffle 63 abuts against the edge of the side plate 7. When the baffle frame 62 rotates to the first position, both ends of the baffle 63 form a gapless contact with the edge of the side plate 7. This can be achieved by setting the matching shape between the ends of the baffle 63 and the edge of the side plate 7. This structure allows the baffle 63 and the side plate 7 to form a complete annular baffle, preventing tea leaves from overflowing from the gap between the edge of the pot body 21 and the baffle during frying or discharge.

[0099] Specifically, during the tea-frying stage, the baffle frame 62 is in the first position, and the baffle component 63 cooperates with the upper edge of the pot body 21 to form a ring-shaped baffle. At this time, both ends of the baffle component 63 are in close contact with the edges of the side plates 7 on both sides of the pot body 21, forming a continuous blocking surface. When it is necessary to switch to the discharge position, the baffle frame 62 is controlled to rotate to the second position, and the baffle component 63 separates from the pot body 21, providing movement space for the wok mechanism to flip. After the discharge is completed, the wok mechanism returns to the tea-frying position, and the baffle frame 62 simultaneously rotates back to the first position, and the baffle component 63 abuts against the edge of the side plate 7 again. During this process, the contact action between the baffle component 63 and the side plate 7 is detected and confirmed by a position sensor to ensure the integrity of the baffle structure. Since the side plates 7 are fixedly set on both sides of the discharge direction of the pot body 21, their positions are precisely matched with the rotation trajectory of the baffle frame 62, so that the baffle component 63 can automatically align with the edge of the side plate 7 when it rotates back into place.

[0100] This solution achieves automatic coordination of workstation switching while ensuring the function of the enclosure through the dynamic cooperation between the side plate 7 and the enclosure component 63. The existing technology has a gap between the enclosure and the side of the pot body 21, causing tea leaves to spill from both sides. This solution fundamentally solves the problem through the edge abutment structure between the side plate 7 and the enclosure component 63.

[0101] Through the above technical solution, this application effectively prevents tea leaves from spilling from both sides of the pot 21 during the stir-frying and unloading process, reducing processing loss. The automatic coordination between the enclosure structure and the switching of the stir-frying station avoids manual intervention and improves production efficiency.

[0102] In addition, in order to increase the smoothness of the operation of this equipment and reduce the vibration during operation, a flywheel 8 is connected to the outer end of the drive shaft 34. The flywheel 8 can effectively unify the vibration generated by each component during operation, increase the stability of the equipment, and reduce the failure rate.
