Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tea processing machinery, and particularly relates to a granular green tea digital automatic processing equipment. BACKGROUND

[0002] Granular green tea has an important position in the tea market due to its unique shape and quality characteristics. During the processing of granular tea, the shape of the leaf will go through the shaping and solidification processes in turn as the moisture gradually loses during the roasting process. Finally, the leaf is processed into granular shape. The traditional processing method mainly relies on manual operation, which has problems such as high labor intensity, low production efficiency, and unstable quality. If a tea roaster is used to form granular tea, the shape change of the leaf depends on the movement state and force of the tea during the roasting process in the tea roaster. The specific forming mechanism is that the leaf will contact the pot wall and roll along the pot wall during the falling process after being lifted, the leaf will be bundled by the tea roaster as it is spread, and the tightness of the leaf bundle will gradually increase as the moisture disappears, and finally a granular shape with uniform texture is formed.

[0003] However, the structure design and roasting method of the existing tea roaster are relatively simple, which cannot meet the forming process requirements of granular tea. Although the production efficiency is improved to some extent, there are still many technical defects: the initial angle of the pot rack swing in the tea roaster is fixed and cannot be adjusted, which leads to the inability to adjust the lifting height and movement state of the tea; in addition, the existing tea roaster mostly uses a fixed pot body, and a fixed fence structure is arranged on the upper edge of the fixed pot body. After the tea roasting is finished, manual discharging is required. The lack of digital control means leads to insufficient processing parameter precision, poor mechanical structure stability affects the reliability of the equipment, and the equipment is easy to be mistakenly turned on and off, which causes safety hazards during the manual discharging process.

[0004] These problems seriously restrict the improvement of the quality and efficiency of granular green tea processing. In particular, in the tea roasting process, how to achieve uniform heating of the tea, accurate control of the processing parameters, and ensure the coordinated operation of the equipment components have become technical problems to be solved.

[0005] In view of the above problems, the existing technology needs to be improved. SUMMARY

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this invention are as follows: 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.

[0018] 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.

[0019] 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.

[0020] 4. The application solves the problem of tea spilling caused by insufficient stability during the turning process of the frying pan, avoids the problem of tea burning caused by temperature fluctuations, and improves processing efficiency through automatic station switching. The real-time monitoring function of the temperature sensor can detect abnormal heating units in time to prevent the whole batch of tea from being scrapped due to equipment failure. The symmetrical bearing seat and fixed shaft structure reduces mechanical wear and prolongs the service life of the equipment.

[0021] 5. The application solves the problem of unstable swing trajectory caused by the asymmetric support structure of the traditional pot rack, effectively improving the uniformity of tea turning. The rigid connection design of the arc-shaped frying plate and the rotating shaft ensures the synchronization of the tea turning action, avoiding local accumulation of tea caused by loose parts. The single-end connection method of the driving mechanism and the rotating shaft simplifies the transmission path, ensuring the efficiency of power transmission while reducing the complexity of the equipment, making it easy for maintenance personnel to quickly repair. This structure design can also adapt to frying pan mechanisms of different sizes. By adjusting the length of the rotating shaft and the arc of the arc-shaped frying plate, the equipment can be expanded, enhancing the versatility of the processing equipment.

[0022] 6. The application solves the problem of frequent maintenance caused by rigid transmission of the traditional tea turning driving mechanism, reducing the equipment failure rate. The combination of chain transmission and eccentric wheel structure realizes decoupling control of tea turning frequency and swing amplitude, allowing operators to dynamically adjust tea turning parameters according to tea moisture content, avoiding problems such as tea spilling during the initial stage of leaf curling or insufficient turning during the late stage of drying. The buffering effect of the connecting rod assembly effectively reduces mechanical impact, prolonging the service life of the transmission components.

[0023] 7. The application realizes accurate control and real-time feedback of the swing angle of the pot rack through the rotating connection design of the ring and the eccentric wheel, ensuring dynamic adaptation of tea turning amplitude at different processing stages and avoiding problems such as uneven heating of tea 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 the driving parameters in time, significantly improving the stability and consistency of equipment operation.

[0024] 8. The application realizes continuous adjustment of the starting angle of the tea turning plate through the cooperation of the guide rail and the driving assembly, solving the problem of uneven heating of tea caused by fixed tea turning angle of existing equipment. By dynamically adjusting the tea turning amplitude to meet the needs of different processing stages, the application avoids tea clumping during the late stage of tea frying. The cooperative control of the phase sensor and the driving assembly improves the automation level of angle adjustment, reduces the need for manual intervention, and ensures the consistency and stability of the processing process.

[0025] 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.

[0026] 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

DETAILED DESCRIPTION

[0030] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail with reference to the accompanying drawings.

[0031] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0034] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0035] In the prior art, there are problems of poor tea turning uniformity, insufficient cooperation between the surrounding barrier and the frying pan, and the like in the processing of granular green tea. The traditional equipment adopts a fixed surrounding barrier assembly structure, which needs to be manually disassembled when the frying pan is turned over to discharge, resulting in complicated operation and easy tea spilling. In the semi-automatic equipment, the angle of the pan support is fixed and cannot be dynamically adjusted according to the processing stage, causing uneven heating of the tea. In addition, the instability of the frying pan support structure causes the pan to shake during turning, affecting the discharge accuracy.

[0036] In order to solve the above problems, it is necessary to design a device that can automatically coordinate the actions of the surrounding barrier and the frying pan, and realize dynamic adjustment of the tea turning angle. Considering the differentiated requirements of tea in different processing stages for the turning amplitude, a pan support with controllable swing range needs to be constructed. In view of the interference problem between the surrounding barrier and the frying pan, a detachable surrounding barrier assembly needs to be developed to provide movement space. At the same time, the stability of the support structure needs to be strengthened to ensure the reliability of the equipment operation.

[0037] Therefore, with reference to Figures 1-7 , the present application proposes a granular green tea digital automatic processing equipment, which comprises a frame type support part 1, a frying pan mechanism, the frying pan mechanism is rotationally connected with the frame type support part 1 so that the frying pan mechanism has a tea frying station for completing tea frying and a discharging station for discharging the processed tea, the frying pan mechanism has an inner concave pan body 21; a pan support rotationally connected with the frame type support part 1, the pan support has an arc-shaped frying plate 31 matched with the inner cavity of the pan body 21; a driving mechanism for driving the arc-shaped frying plate 31 to swing back and forth in the pan body 21; a phase adjusting mechanism for controlling the swing angle of the arc-shaped frying plate 31; a surrounding barrier mechanism comprising a movable surrounding barrier assembly rotationally connected with the frame type support part 1 and a fixed surrounding barrier assembly fixed to the discharging side of the frying pan mechanism, before the frying pan mechanism is switched from the tea frying station to the discharging station, the movable surrounding barrier assembly is rotated and separated from the fixed surrounding barrier assembly to provide movement space for the station switching of the frying pan mechanism.

[0038] The frame support part 1 is a main body structure for bearing various components of the equipment, which can be constructed by combining a metal frame and a transverse reinforcing beam, and functions to provide stable support for the rotation of the frying pan. The frying pan mechanism includes an inner concave pan body 21 and a rotating connection component, which is realized by cooperating a bearing seat with a fixed shaft 201 to realize 50-90 degree overturning, for switching between processing and discharging states. The arc-shaped frying plate 31 is a metal plate matched with the inner cavity curved surface of the pan body 21, which is driven to realize reciprocating swing through the rotating shaft 3, and the arc design can reduce the damage of tea leaves. The driving mechanism includes a motor and a transmission assembly, which converts the rotary motion into the swing action of the frying plate through the gear chain 35 and the connecting rod mechanism. The phase adjustment mechanism includes an angle sensor and a controller, which controls the swing amplitude of the frying plate by adjusting the stroke of the motor. The movable fence assembly includes a rotatable support shaft 6 and a fence 63, which is separated from the fixed fence by the motor before the frying pan overturns, to avoid mechanical interference.

[0039] Specifically, during the tea frying stage, the frying pan is in a horizontal working position, and the fence assembly is closed to form a continuous fence. The driving mechanism drives the arc-shaped frying plate 31 to swing at a set angle, so that the tea leaves are uniformly heated. When the processing is completed, the controller starts the fence motor to rotate the movable fence outward to the separation position. Then the frying pan driving motor works to drive the pan body 21 to overturn to the discharging working position, and the tea leaves slide out along the inclined pan surface. The fence separation action and the frying pan overturning form a time sequence cooperation in this process, without manual intervention. The swing angle of the pan rack can be adjusted by the controller according to the water content of the tea leaves, a small angle swing is used in the early stage to prevent spilling, and the angle is increased in the later stage to promote the formation of particles.

[0040] Compared with the prior art, the fixed fence of the traditional equipment needs to be manually disassembled, and the automatic separation of the movable fence in the present solution eliminates the risk of mechanical interference. The problem of unadjustable tea overturning angle in the semi-automatic equipment is solved by the adjustable connecting rod mechanism and the phase sensor in the present solution.

[0041] Through the above technical solution, the present application realizes the automatic cooperation of the fence and the frying pan action, avoids the efficiency loss caused by manual disassembly. The dynamic adjustment function of the tea overturning angle makes the tea leaves obtain appropriate overturning amplitude in different processing stages, which improves the uniformity of heating. The movable fence cooperates with the double-bearing support structure to ensure the stability of processing while improving the discharging efficiency and reducing the tea loss.

[0042] The present application further proposes a control system, which has an instruction input end, a controller, and a data acquisition unit. The controller is used to control the heating temperature and heating time of the frying pan mechanism; the controller is used to control the operation or stop of the driving mechanism; the controller is used to control the phase adjustment mechanism to adjust the swing angle of the arc-shaped frying plate 31; and the controller is used to control the movable fence assembly to separate from the frying pan mechanism before the frying pan mechanism is switched from the tea frying working position to the discharging working position.

[0043] The instruction input end is an input interface for receiving operation instructions, which can be implemented by a touch screen or physical buttons, and is used to set the heating temperature range, processing time parameters, and tea turning angle parameters, and display the running state of each mechanism. The controller is a control unit for performing logical operations, which can be implemented by a PLC or an embedded microprocessor, and generates corresponding control signals to adjust the power of the heating unit 23, the speed of the drive motor, and the action timing of the surrounding mechanism by receiving parameter settings from the instruction input end. The data acquisition unit is a sensor assembly for collecting equipment operation data, which can be implemented by temperature sensors, angle sensors, and position sensors, and is used to obtain real-time pot body 21 temperature data, turning plate swing angle data, and surrounding position state data.

[0044] Specifically, the control system receives the temperature threshold, processing time, and tea turning angle parameters set by the operator through the instruction input end, and the controller generates corresponding control instructions 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 body 21 within the set range; at the same time, the controller sends start and stop instructions to the drive mechanism to make the pot rack swing at the set frequency. When it is necessary to switch to the discharge station, the controller sends a separation instruction to the surrounding mechanism to release the contact with the pot body 21 in advance. The data acquisition unit collects the running data of each execution mechanism in real time and feeds back to the controller, forming a closed-loop control loop to ensure stable execution of the processing parameters.

[0045] Compared with the prior art, the traditional semi-automatic equipment relies on manual experience to adjust the heating power and tea turning frequency, which has the problems of large parameter fluctuation and response lag. The present scheme realizes accurate parameter setting and automatic adjustment through a digital control system, avoids manual operation errors, realizes real-time monitoring of the running state through the integrated data acquisition unit, can quickly identify abnormal equipment states, and reduces the risk of processing interruption.

[0046] Through the above technical scheme, the present application realizes accurate control of tea frying temperature and time, ensures stable heat treatment effect during the curling and forming process of the tea frying process, improves tea turning uniformity and discharge efficiency through programmed control of tea turning angle and surrounding action timing, and reduces the risk of tea loss caused by equipment failure through real-time data acquisition and feedback mechanism.

[0047] The present application further proposes that the data acquisition unit is used to collect data of the frying pan mechanism, the drive mechanism, the phase adjustment mechanism, and the movable surrounding assembly during operation to monitor the running state of any mechanism in real time.

[0048] The data acquisition unit is a device for collecting operating parameters of each component of the equipment, which can be realized by a temperature sensor, an angle sensor, and a position sensor, for example, a temperature sensor is arranged on the surface of the pot body 21 to monitor the heating temperature, an angle sensor is arranged at the end of the rotating shaft 3 to detect the swing angle of the pot rack, and a position sensor is arranged near the fence assembly to confirm the station state. These sensors feed real-time data to the control system, so that operation abnormalities can be found in time.

[0049] Specifically, the data acquisition unit continuously collects the temperature of the frying pan mechanism, the operating frequency of the driving mechanism, the adjustment range of the phase adjustment mechanism, and the position signal of the fence assembly through a sensor network distributed at key positions of the equipment. For example, when the temperature of the pot body 21 of the frying pan mechanism deviates from the set range, the temperature sensor transmits a signal to the controller to trigger the temperature compensation mechanism; when the swing angle of the pot rack exceeds the preset threshold, the angle sensor sends an alarm signal to the operation interface to prompt maintenance; when the fence assembly does not reach the designated station within the predetermined time, the position sensor generates a fault code to suspend the operation of the equipment to avoid mechanical interference. Thus, the operating state of each mechanism is monitored in real time to ensure the stability of the processing flow.

[0050] Compared with the prior art, the existing semi-automatic equipment lacks real-time acquisition and feedback of operating parameters, for example, it cannot monitor whether the pot rack is stuck or the heating unit 23 is failed, which makes it difficult to find processing abnormalities in time. However, the present scheme can dynamically track and monitor the operating data of each mechanism by integrating the data acquisition unit, for example, by capturing the swing amplitude change of the pot rack through the angle sensor to identify the wear of the connecting rod or the abnormal load of the driving motor, thereby warning before failure occurs to avoid the problem of tea edge burning or caking caused by uneven turning.

[0051] Through the above technical scheme, the present application realizes continuous monitoring of key operating parameters of the equipment, for example, real-time acquisition of the temperature fluctuation of the pot body 21, the turning angle deviation of the tea, and the position state of the fence during the tea frying process, to ensure that the processing parameters are always within the controllable range. At the same time, the collected historical data can be used to optimize the processing technology, for example, adjusting the heating strategy according to the temperature curve to improve the processing efficiency and product consistency.

[0052] Referring to Figures 1-3The application further provides a granular green tea digital automatic processing equipment, which comprises a frying pan mechanism, the frying pan mechanism comprises a pan frame 2 for fixing a pan body 21, the bottom of the pan body 21 is provided with heating units 23 arranged in sections, a data acquisition unit comprises a temperature sensor arranged on the surface of the pan body 21, the frame type support part 1 is symmetrically provided with first bearing seats 22 for supporting the pan frame 2 on both sides, the pan frame 2 is fixedly connected with fixed shafts 201 on both sides, the fixed shafts 201 are connected with the bearing seats, the bottom of the pan frame 2 is provided with a semicircular plate 24, the edge of the semicircular plate 24 is provided with driving teeth 241, a frying pan control motor 25 is fixedly connected to the frame type support part 1, the output end of the frying pan control motor 25 is fixedly connected with a first driving gear 251 engaged with the driving teeth 241, the rotation angle of the pan frame 2 is 50-120°, and the frying pan control motor 25 is electrically connected with a controller so that the controller controls the pan frame 2 to switch between a tea frying station and a discharging station through the frying pan control motor 25.

[0053] The pan frame 2 is a support structure for fixing the pan body 21 and can be formed by welding a metal frame, which provides stable support for the pan body 21 and transmits the overturning driving force. The heating unit 23 is a device for heating the pan body 21 and can be an electric heating tube or an electromagnetic heating coil, which realizes tea leaf curling and drying through precise temperature control. Each heating unit 23 in the partitioned heating unit 23 is independently controlled, and users can independently set the heating units 23 in each partition according to process requirements, so that the temperatures of each partition remain consistent or are customized to be different to adapt to different processing processes. The temperature sensor is an element for detecting the surface temperature of the pan body 21 and can be a thermocouple or an infrared temperature measurement module, which feeds 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 and can be a rolling bearing or a sliding bearing, which supports the pan frame 2 through the fixed shaft 201 and reduces the rotational friction resistance. The semicircular plate 24 is an arc-shaped structure fixed to the bottom of the pan frame 2 and can be formed by cutting a steel plate, which transmits torque through the engagement of the driving teeth 241 and the first driving gear 251. The first driving gear 251 is a gear connected with the output end of the frying pan control motor 25 and can be a helical gear or a spur gear, which converts the rotary motion of the motor into the overturning action of the pan frame 2. The rotation angle of the pan frame 2 is 50-120°, which is the overturning range of the frying pan between the tea frying station and the discharging station, and can be controlled by a limit switch or an encoder, which realizes the automatic switching of tea processing and pouring.

[0054] Specifically, after the pot body 21 is fixed by the pot rack 2, the fixed shafts 201 on both sides are embedded in the first bearing seat 22 to form stable support, avoiding axial deviation when the wok is turned over. The driving teeth 241 at the bottom of the semicircular plate 24 are engaged with the first driving gear 251, when the wok control motor 25 is started, the gear transmission drives the pot rack 2 to rotate around the fixed shaft 201, so that the pot body 21 switches the work position within the range of 50-120°. The temperature sensor collects the surface temperature data of the pot body 21 in real time and transmits it to the controller, and the controller adjusts the power of the heating unit 23 according to the preset program to ensure stable processing temperature. When discharging is needed, the controller drives the wok control motor 25 to reverse, and the pot rack 2 drives the pot body 21 to tilt to the discharging work position, and the tea leaves automatically slide out under the action of gravity.

[0055] Compared with the prior art, the traditional device uses single-sided bearing seat support, which causes the pot body 21 to shake, while the symmetrical first bearing seat 22 cooperates with the fixed shaft 201 to significantly improve the structural stability. The existing device relies on manual observation to judge the pot temperature, while the closed-loop control of the temperature sensor and the heating unit 23 realizes accurate temperature adjustment. The semi-automatic device needs to manually operate the pot body 21 to turn over, while the wok control motor 25 and the gear transmission mechanism realize automatic switching of the work position, reducing manual intervention.

[0056] Through the above technical scheme, the present application solves the problem of tea spilling caused by insufficient stability during the turning over of the wok, avoids the tea being burnt caused by temperature fluctuations, and improves the processing efficiency through automatic work position switching. The real-time monitoring function of the temperature sensor can detect abnormal heating unit 23 in time to prevent the whole batch of tea from being scrapped due to equipment failure. The symmetrical bearing seat and the fixed shaft 201 structure reduce mechanical wear and prolong the service life of the equipment.

[0057] Referring to Figures 1-3 and Figure 6 and Figure 7 , the present application further proposes that the pot rack comprises second bearing seats 32 symmetrically arranged on both sides of the frame support 1, and a rotating shaft 3 is fixedly connected between the two second bearing seats 32. The arc-shaped frying plate 31 is fixedly connected with the rotating shaft 3, and the driving mechanism is connected with one end of the rotating shaft 3 to drive the rotating shaft 3 to rotate forward and backward.

[0058] The second bearing seat 32 is a support structure symmetrically arranged on both sides of the frame, which can be realized by a metal seat body with a rolling bearing, used to bear the rotating shaft 3 and ensure its rotation stability. The rotating shaft 3 is a rigid shaft body transversely penetrating the two second bearing seats 32, which can be realized by a hollow pipe made of stainless steel, used to transmit driving force and drive the arc-shaped frying plate 31 to swing synchronously. The arc-shaped frying plate 31 is a curved surface structure fixedly connected with the rotating shaft 3, which can be realized by an arc-shaped metal plate formed by stamping, and the curvature thereof matches the profile of the inner cavity of the pot body 21 to improve the coverage range of tea turning. The driving mechanism is connected with the rotating shaft 3 to transmit power to the rotating shaft 3 through a mechanical transmission assembly, which can be realized by a combination structure of an eccentric wheel 342 and a connecting rod, and the rotary motion is converted into reciprocating swing.

[0059] Specifically, the symmetrically arranged second bearing seat 32 provides bilateral support for the rotating shaft 3, effectively reduces the radial runout of the rotating shaft 3 during operation, and ensures the stability of the swing trajectory of the arc-shaped frying plate 31. The rotating shaft 3 penetrates the two bearing seats and is rigidly connected with the arc-shaped frying plate 31, so that the power output by the driving mechanism can be uniformly transmitted to the whole frying plate. The driving mechanism drives the rotating shaft 3 to rotate forward and backward, driving the arc-shaped frying plate 31 to swing periodically in the inner cavity of the pot body 21. During the swinging process, the edge of the frying plate cooperates with the inner wall of the pot body 21 with a gap, which not only realizes the sufficient turning of tea leaves, but also avoids friction loss with the pot body 21. The swing amplitude of the arc-shaped frying plate 31 is determined by the stroke of the driving mechanism, and the reciprocating motion trajectory covers the bottom to the sidewall region of the pot body 21, ensuring that the tea leaves at different processing stages can be uniformly turned.

[0060] Compared with the prior art, the traditional pot rack mostly adopts a single-sided support rotating shaft 3 structure, which is easy to cause the rotating shaft 3 to be inclined due to uneven stress, and then causes the frying plate to be stuck or the swing angle to be deviated. The combination design of the bilateral symmetric bearing seat and the rigid rotating shaft 3 in the present scheme significantly improves the running stability of the rotating shaft 3, so that the swing angle control of the frying plate is more accurate. In addition, in the prior art, the tea turning driving mostly relies on gear direct transmission, which has the problem of transmission efficiency reduction caused by gear wear, while the present scheme adopts the transmission mode of eccentric wheel 342 and connecting rod, which reduces mechanical impact through flexible connection and prolongs the service life of the driving mechanism.

[0061] By the technical scheme, the application solves the problem of unstable swing track caused by the unsymmetrical support structure of the traditional pot rack, and effectively improves the uniformity of tea turning. The rigid connection design of the arc-shaped frying plate 31 and the rotating shaft 3 ensures the synchronization of the tea turning action, and avoids local accumulation of tea caused by loose parts. The single-end connection mode of the driving mechanism and the rotating shaft 3 simplifies the transmission path, reduces the complexity of the equipment while ensuring the power transmission efficiency, and facilitates quick maintenance for maintenance personnel. The structure design can also adapt to frying pan mechanisms of different sizes, and the equipment can be expanded by adjusting the length of the rotating shaft 3 and the arc of the arc-shaped frying plate 31, thereby enhancing the versatility of the processing equipment.

[0062] With reference to Figures 1-5 The application further proposes that the driving mechanism comprises a frying plate control motor 33 fixed on the frame support 1, a transmission shaft 34 rotationally connected with the frame support 1, and the output end of the frying plate control motor 33 is fixedly connected with a second driving gear 331, the end of the transmission shaft 34 is provided with a driven gear 341, a chain 35 is connected between the driving gear and the driven gear 341, the transmission shaft 34 is fixedly connected with an eccentric wheel 342, and a connecting rod assembly is arranged between one end of the rotating shaft 3 and the eccentric wheel 342. The eccentric wheel 342 rotationally drives the rotating shaft 3 to reciprocatingly rotate in forward and reverse directions through the connecting rod assembly.

[0063] The frying plate control motor 33 is a power output unit, which can be specifically implemented by a servo motor or a stepping motor, and is used to provide a controllable power source for the pot rack. The transmission shaft 34 is a power transmission unit, which can be specifically implemented by a steel shaft body cooperating with a bearing seat, and is used to transmit the rotary power of the frying plate control motor 33 to the eccentric wheel 342. The chain 35 transmission is a power transmission mode, which can be specifically implemented by a roller chain 35 cooperating with a sprocket, and is used to isolate the vibration of the motor and adapt to the long-distance transmission requirement. The eccentric wheel 342 is a motion conversion unit, which can be specifically implemented by a disc structure cooperating with an off-center shaft hole, and is used to convert rotary motion into reciprocating swing. The connecting rod assembly is a motion transmission unit, which can be specifically implemented by a hinged metal rod, and is used to convert the circular motion of the eccentric wheel 342 into the reciprocating swing of the rotating shaft 3.

[0064] Specifically, the frying plate control motor 33 drives the chain 35 through the driving gear, and drives the driven gear 341 on the transmission shaft 34 to rotate synchronously. The transmission shaft 34 drives the eccentric wheel 342 to continuously rotate, and the circular motion of the outer edge of the eccentric wheel 342 is converted into the reciprocating swing of the rotating shaft 3 through the connecting rod assembly. The rotating shaft 3 drives the arc-shaped frying plate 31 to perform a periodic tea turning action in 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 of the eccentric wheel 342 and the connecting rod assembly makes the tea turning swing angle adjustable. By controlling the rotating speed of the frying plate control motor 33, the tea turning frequency can be accurately adjusted to adapt to the tea state in different processing stages.

[0065] Compared with the prior art, the traditional tea turning driving mechanism is directly engaged by a gear, and the long-term operation is prone to cause the transmission gap to increase due to gear wear, and then cause the tea turning angle to deviate or the mechanism to be stuck. The scheme adopts a chain 35 transmission to replace the gear direct connection, and uses the flexible transmission characteristics of the chain 35 to reduce the risk of gear wear. At the same time, the combination structure of the eccentric wheel 342 and the connecting rod assembly replaces the traditional fixed-angle tea turning driving mode, so that the tea turning angle can be dynamically adjusted by adjusting the phase of the eccentric wheel 342 or the length of the connecting rod, and the adaptability of the equipment to different processing stages is significantly improved.

[0066] Through the above technical scheme, the present application solves the problem of frequent maintenance caused by the traditional tea turning driving mechanism due to rigid transmission, and reduces the equipment operation failure rate. The cooperation of the chain 35 transmission and the eccentric wheel 342 structure realizes the decoupling control of the tea turning frequency and the swing amplitude, so that the operator can dynamically adjust the tea turning action parameters according to the water content of the tea leaves, avoiding the problems of tea leaf spilling in the initial stage of leaf curling and forming or insufficient turning in the late stage of frying. The buffering effect of the connecting rod assembly effectively reduces the mechanical impact and prolongs the service life of the transmission components.

[0067] Referring to Figures 1-7 , the present application further proposes a connecting rod mechanism including a connecting rod seat 4 arranged on the frame support 1, a vertical connecting rod 41 arranged vertically and rotatably connected to the connecting rod seat 4, a horizontal connecting rod 42 hingedly connected to the side wall of the vertical connecting rod 41, a ring sleeve 421 arranged on the end of the horizontal connecting rod 421 away from the vertical connecting rod 41, the ring sleeve 421 being arranged 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 hingedly connected to the upper end of the vertical connecting rod 41, a connecting shaft 301 eccentrically fixedly connected to the end of the rotating shaft 3 close to the arc-shaped swing arm 43, the end of the arc-shaped swing arm 43 away from the vertical connecting rod 41 being hingedly connected to the connecting shaft 301, and a data acquisition unit including an angle sensor for detecting the rotation angle of the connecting shaft 301.

[0068] The connecting rod seat 4 is a support structure for bearing the vertical connecting rod 41, which can be formed by cast iron material, and a rolling bearing is arranged in the connecting rod seat 4 to realize the rotary connection of the vertical connecting rod 41, and the 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, which can be made of a hollow steel pipe, and the design that the side wall of the vertical connecting rod 41 is hingedly connected with the horizontal connecting rod 42 can avoid motion interference. The horizontal connecting rod 42 is a transverse rod for connecting the vertical connecting rod 41 and the eccentric wheel 342, which can be made of an aluminum alloy profile, one end of the horizontal connecting rod 42 is connected with the vertical connecting rod 41 through a hinge, and the other end of the horizontal connecting rod 42 is provided with a ring sleeve 421 structure. The ring sleeve 421 is an annular connecting piece sleeved on the outer wall of the eccentric wheel 342, which can be made of nylon material, and a ball bearing is arranged on the inner wall of the ring sleeve 421 to realize the rotary connection with the eccentric wheel 342, and the structure can convert the rotary motion of the eccentric wheel 342 into the reciprocating swing of the horizontal connecting rod 42. The arc-shaped swing arm 43 is a curved force transmission component for connecting the vertical connecting rod 41 and the rotating shaft 3, which can be formed by bending a stamping steel plate, and the arc-shaped trajectory of the arc-shaped swing arm 43 can adapt to the eccentric swing path of the rotating shaft 3. The connecting shaft 301 is a transmission component fixedly arranged on the rotating shaft 3 and eccentrically arranged, which can be a stepped shaft structure, and the eccentric distance of the connecting shaft 301 can be designed to adjust the swing amplitude of the flap. The angle sensor is a measuring device for detecting the rotation angle of the connecting shaft 301, which can be an optical encoder or a potentiometer type sensor, and the signal output end of the angle sensor is connected with the control system to realize the closed-loop control of the swing angle of the flap.

[0069] When the driving mechanism drives the eccentric wheel 342 to rotate, the ring sleeve 421 moves along the outer wall of the eccentric wheel 342 in a circular motion, and pushes 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 the hinge, so that the vertical connecting rod 41 swings up and down about the axis of the connecting rod seat 4. The arc-shaped swing arm 43 at the top of the vertical connecting rod 41 moves along an arc-shaped trajectory, and drives the connecting shaft 301 to eccentrically rotate through the hinge joint. Since the connecting shaft 301 is fixedly connected with the rotating shaft 3, the rotating shaft 3 is driven to rotate forward and backward reciprocally, so as to drive the arc-shaped frying plate 31 to swing in the pot 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 it is detected that the actual swing angle deviates from the set range, the controller can dynamically adjust the operating parameters of the driving mechanism to correct the deviation.

[0070] Compared with the prior art, the connecting rod assembly of the traditional pot rack is rigidly connected and lacks an angle feedback mechanism, which causes the swing angle of the flap to be uncontrollable, and the tea leaves are easily unevenly stirred or the mechanism is easily stuck. The rotation connection design of the ring sleeve 421 and the eccentric wheel 342 in the scheme reduces the motion friction, the combination of the arc-shaped swing arm 43 and the eccentric connecting shaft 301 realizes the swing trajectory optimization, and the real-time monitoring function of the angle sensor effectively solves the technical problems of large swing angle fluctuation of the tea and low control precision.

[0071] Through the technical scheme, the application realizes accurate control and real-time feedback of the swing angle of the pot rack, ensures dynamic adaptation of the tea turning range in different processing stages, and avoids problems of uneven heating of tea or mechanical jam caused by angle deviation. The introduction of the angle sensor enables the control system to quickly identify abnormal swing state, adjust the driving parameters in time, and significantly improve the stability and processing consistency of the equipment operation.

[0072] With reference to Figures 1-3 and Figure 7 , the application further proposes a phase adjusting mechanism including a bushing 5 fixed on the frame support 1, a lead screw threadedly connected in the bushing 5, a connecting rod seat 4 and a driven pulley 511 respectively arranged at both ends of the lead screw, a vertical connecting rod 41 hingedly connected to the connecting rod seat 4, a phase adjusting motor 53 arranged on the frame support 1, a driving pulley 531 arranged at the output end of the phase adjusting motor 53, a belt 54 connected between the driving pulley 531 and the driven pulley 511, and a data acquisition unit including two groups of phase sensors arranged along the guide rails at intervals, the positions of the two groups of phase sensors respectively corresponding to the minimum distance and the maximum distance of the horizontal movement of the connecting rod seat 4, thereby limiting the minimum value and the maximum value of the initial angle of the reciprocating swing of the rotating shaft 3.

[0073] The cooperation between the bushing 5 and the lead screw in the driving assembly is to convert the rotary motion into linear motion through the thread pair, which can be realized by using a ball screw or a trapezoidal screw, and the function is to accurately control the displacement amount of the connecting rod seat 4 through the rotation of the lead screw. The driven pulley 511 and the driving pulley 531 are connected through the belt 54 to utilize the belt transmission to transmit power, which can be realized by using a synchronous belt or a V-shaped belt, and the function is to transmit the rotary power of the phase adjusting motor 53 to the lead screw. The phase sensor is a sensing element for detecting the position of the connecting rod seat 4, which can be realized by using a photoelectric sensor or a proximity switch, and the function is to limit the initial angle of the swing of the rotating shaft 3 by detecting whether the connecting rod seat 4 reaches the preset position.

[0074] Specifically, when adjusting the initial angle of the arc-shaped frying plate 31, the phase adjustment motor 53 is started to drive the driving pulley 531 to rotate, and the driven pulley 511 and the lead screw are driven to rotate synchronously through the belt 54. The rotary motion of the lead screw is converted into the axial movement of the lead screw in the bushing 5 through the screw pair, and then the horizontal movement of the connecting rod seat 4 is driven. When the connecting rod seat 4 moves to the end closest to the bushing 5, one of the phase sensors is triggered, and at this time, the initial angle of the arc-shaped frying plate 31 reaches the minimum value. In this state, the reciprocating swing of the arc-shaped frying plate 31 can make the throwing height of the tea in the pot reach the maximum value, and the diameter of the tea particles obtained by processing is the smallest; when the connecting rod seat 4 moves to the farthest end away from the bushing 5, the other phase sensor is triggered, and at this time, the initial angle of the arc-shaped frying plate 31 reaches the maximum value. In this state, the reciprocating swing of the arc-shaped frying plate 31 can make the throwing height of the tea in the pot reach the minimum value, and the diameter of the tea particles obtained by processing is the largest. By controlling the forward and reverse rotation of the phase adjustment motor 53, the relative position of the lead screw and the bushing 5 can be dynamically adjusted, thereby continuously changing the swing angle range of the arc-shaped frying plate 31, and adapting to the requirements of the initial angle of the tea turning at different processing stages.

[0075] Compared with the prior art, the initial angle of the pot rack reciprocating swing of the traditional semi-automatic tea frying equipment is fixed, and the initial angle of the turning cannot be adjusted according to the state of the tea, resulting in that only tea particles of a single diameter can be processed, and the processing product type is relatively single. The present scheme realizes the continuous adjustment of the initial angle of the frying plate swing within a certain range through the cooperation of the bushing 5 and the lead screw, for example, a smaller throwing height is adopted in the drying stage to avoid tea spilling, and a larger throwing height is switched to in the forming stage to promote particle formation. The setting of the phase sensor further ensures the accuracy and reliability of the swing angle adjustment, and avoids the angle deviation caused by mechanical errors.

[0076] In addition, as a preferred embodiment of the phase adjustment mechanism, a rotation angle detection assembly is installed at the outer end of the driven pulley 511 for detecting the rotation angle of the driven pulley 511 and then converting it into the displacement amount of the connecting rod seat 4, and the initial angle of the arc-shaped frying plate 31 is accurately adjusted through the controller. The preferred setting mode of the rotation angle detection assembly is that a circular baffle is fixed on the driven pulley 511, a plurality of hollow areas are arranged on the outer side of the circular baffle at equal intervals, and a light barrier sensor is further included. The circular baffle rotates synchronously with the driven pulley 511, the light beam emitted by the light barrier sensor is perpendicular to the circular baffle, and the light barrier sensor receives a trigger signal once every time a hollow area passes through the light beam emitted by the light barrier sensor. Each time a signal is triggered, it means that the driven pulley 511 has rotated by a unit angle, for example, 10°, and then the initial angle of the arc-shaped frying plate 31 is accurately and automatically controlled.

[0077] By the technical scheme, the present application solves the problem of uneven heating of tea leaves caused by the fixed tea turning angle of the existing equipment, and the tea turning range is dynamically adjusted to adapt to the requirements of different processing stages, thereby avoiding tea clumping in the later tea frying stage. The cooperative control of the phase sensor and the driving assembly improves the automation level of angle adjustment, reduces the need for manual intervention, and ensures the consistency and stability of the processing process.

[0078] With reference to Figures 1-3 The present application further provides a surrounding fence mechanism, which comprises two groups of third bearing seats 61 symmetrically arranged on both sides of the frame support part 1, a support shaft 6 fixedly connected between the two groups of third bearing seats 61, a surrounding fence frame 62 fixedly connected to the support shaft 6, a surrounding fence piece 63 fixedly connected to the end of the surrounding fence frame 62 away from the support shaft 6 and matched with the upper edge of the kettle body 21, a first gear 64 arranged at the end of the support shaft 6, a surrounding fence control motor 65 fixedly connected to the frame support part 1, a second gear fixedly connected to the output end of the surrounding fence control motor 65 and engaged with the first gear 64, and a controller electrically connected to the surrounding fence control motor 65 to control the rotation of the surrounding fence frame 62. The surrounding fence frame 62 has a first station at which the surrounding fence piece 63 is matched with the upper edge of the kettle body 21 and a second station at which the surrounding fence piece 63 is separated from the upper edge of the kettle body 21 and does not interfere with the rotation of the kettle rack 2. The two groups of position sensors are arranged at positions corresponding to the first station and the second station of the surrounding fence frame 62, respectively.

[0079] The third bearing seat 61 is a fixed base for mounting the support shaft 6, which can be realized by a rolling bearing seat with a sealing structure, and the symmetric arrangement ensures the stability of the support shaft 6 during rotation. The support shaft 6 is a rigid shaft body penetrating through the two groups of third bearing seats 61, which can be realized by an alloy steel shaft with chrome plating on the surface and is used to bear the rotation torque of the surrounding fence frame 62. The surrounding fence frame 62 is a frame structure connecting the support shaft 6 and the surrounding fence piece 63, which can be realized by a stainless steel welded truss, and the surrounding fence piece 63 arranged at the end of the surrounding fence frame 62 away from the support shaft 6 can form a continuous closed structure with the upper edge of the kettle body 21. The first gear 64 and the second gear constitute a speed reduction transmission pair, which can be realized by a bevel gear set with a module of 3, and the position switching of the surrounding fence frame 62 is realized by driving the surrounding fence control motor 65. The position sensor is a detection element for detecting the rotation angle of the surrounding fence frame 62, which can be realized by a Hall sensor or a photoelectric sensor, and the two groups of sensors correspond to the limit positions of the first station and the second station, respectively.

[0080] Specifically, at the tea frying station, the fence control motor 65 drives the support shaft 6 to rotate through gear transmission, so that the fence frame 62 drives the fence piece 63 to press down to the upper edge of the kettle body 21 to form a closed fence. When it is needed to switch to the discharging station, the controller sends a command to start the fence control motor 65 to rotate in reverse, and the fence frame 62 is lifted upward to separate the fence piece 63 from the kettle body 21. The two groups of position sensors detect the rotation angle of the fence frame 62 in real time, and when it is detected that the fence piece 63 reaches the preset first station or second station, a feedback signal is fed back to the controller to cut off the power supply of the fence control motor 65. In this process, the lifting path of the fence piece 63 avoids the overturning track of the kettle rack 2, avoiding mechanical interference.

[0081] Compared with the prior art, the existing tea frying machine mostly adopts a fixed kettle body, and a fixed fence structure is arranged on the upper edge of the fixed kettle body. After tea frying is completed, manual discharging is needed. Lack of digital control means leads to insufficient processing parameter precision, poor mechanical structure stability affects equipment reliability, and safety hazards exist in the manual discharging process due to accidental operation of the equipment. The fence frame 62 is automatically lifted by the motor drive, and the fence separation action is completed before the kettle body 21 is overturned, without manual intervention. The closed-loop detection of the fence station state is realized by the position sensor, and the timing accuracy of the fence separation action and the overturning of the frying kettle is ensured.

[0082] Through the above technical scheme, the problem of mechanical interference between the fence and the kettle body 21 when the frying kettle is overturned is solved. While ensuring that the tea leaves are not spilled during the curling and forming process, the granular tea frying machine is also automatically discharged. The automatic lifting action of the fence piece 63 cooperates with the overturning of the kettle rack 2 to shorten the station switching time and improve the discharging efficiency. The double detection mechanism of the position sensor ensures the reliability of the fence station switching and prevents the equipment from being stuck due to incomplete separation of the fence.

[0083] Reference Figures 1-3 The application further proposes a granular green tea digital automatic processing equipment. The kettle body 21 is fixedly connected with side plates 7 on both sides. When the fence frame 62 rotates from the second station to the first station, the two ends of the fence piece 63 abut against the edges of the two side plates 7 to form a continuous fence structure.

[0084] The side plate 7 is a plate-shaped structure fixed on both sides of the discharging direction of the kettle body 21, which can be fixed on the outer wall of the kettle body 21 by welding or bolt connection of metal plate, and the height can be set to be flush with the upper edge of the kettle body 21 or slightly higher than the edge of the kettle body 21. When the wok mechanism is in the discharging station, it can block the tea from spilling from both sides of the kettle body 21, reducing the tea loss during discharging. When the surrounding blocking piece 63 abuts against the edge of the side plate 7, the two ends of the surrounding blocking piece 63 form a gapless contact with the edge of the side plate 7, which can be realized by setting the matching shape of the end of the surrounding blocking piece 63 and the edge of the side plate 7. This structure makes the surrounding blocking piece 63 and the side plate 7 form a complete annular enclosure together, avoiding the overflow of tea from the gap between the edge of the kettle body 21 and the enclosure during the turning and discharging process.

[0085] Specifically, in the tea roasting station stage, the surrounding blocking frame 62 is in the first station, and the surrounding blocking piece 63 cooperates with the upper edge of the kettle body 21 to form an annular enclosure, and at this time the two ends of the surrounding blocking piece 63 are in close contact with the edges of the side plates 7 on both sides of the kettle body 21, forming a continuous blocking surface. When it is necessary to switch to the discharging station, the surrounding blocking frame 62 is controlled to rotate to the second station, and the surrounding blocking piece 63 is separated from the kettle body 21 to provide a movement space for the wok mechanism to turn over. After discharging is completed, the wok mechanism is reset to the tea roasting station, and the surrounding blocking frame 62 is synchronously rotated to the first station, and the surrounding blocking piece 63 abuts against the edge of the side plate 7 again. In this process, the contact action of the surrounding blocking piece 63 and the side plate 7 is detected and confirmed by the position sensor to ensure the integrity of the surrounding blocking structure. Since the side plate 7 is fixedly arranged on both sides of the discharging direction of the kettle body 21, its position is accurately matched with the rotation track of the surrounding blocking frame 62, so that the surrounding blocking piece 63 can be automatically aligned with the edge of the side plate 7 when it is rotated to the position.

[0086] The present application realizes the automatic cooperation of station switching while ensuring the surrounding blocking function through the dynamic cooperation of the side plate 7 and the surrounding blocking piece 63. The gap between the surrounding blocking piece and the side of the kettle body 21 in the prior art causes tea to spill from both sides, which is fundamentally solved in the present application through the edge abutting structure of the side plate 7 and the surrounding blocking piece 63.

[0087] Through the above technical scheme, the present application effectively prevents tea from spilling from both sides of the kettle body 21 during the turning and discharging process, and reduces the processing loss rate. The automatic cooperation of the surrounding blocking structure and the wok station switching avoids manual intervention and improves production efficiency.

[0088] In addition, in order to increase the stability of the operation of the equipment and reduce the vibration in the running state, a flywheel 8 is connected to the outer end of the transmission shaft 34, which can effectively reduce the vibration generated during the operation of each component, increase the stability of the equipment, and reduce the failure rate.
