Description

Technical Field

[0001] This invention belongs to the field of tea processing, and in particular relates to a tilting and discharging structure for tea stir-frying. Background Technology

[0002] Tea processing is a crucial step in improving tea quality and maximizing the economic value of fresh leaves. Stir-frying is a core process in the withering and shaping of tea leaves. After stir-frying, the tea leaves need to be promptly removed, dispersed, and cooled to ensure their color, aroma, and taste, and to prevent quality degradation due to heat buildup. Currently, my country's tea processing machinery is developing towards standardization, continuous processing, and automation; however, many technical challenges remain in the stir-frying and discharging stage.

[0003] In current tea processing, the tea leaves are often directly poured out of the stir-frying machine, and then manually distributed and cooled. This method has the following problems: First, the tea leaves are still hot after stir-frying, and when poured out directly, they tend to clump together. The heat of the inner tea leaves is difficult to dissipate, causing the tea to remain hot and humid, resulting in a musty taste. At the same time, the leaves darken and turn yellow, seriously affecting the quality of the tea. Second, the tea leaves fall in a concentrated manner during the discharge process, easily accumulating on the conveyor equipment, resulting in low cooling efficiency. Furthermore, the continuous falling of tea leaves will aggravate the accumulation and further deteriorate the heat dissipation effect. Summary of the Invention

[0004] The purpose of this invention is to provide a pouring and discharging structure for tea stir-frying, aiming to solve the technical problem in the prior art where direct pouring causes the heat of the tea to not be dissipated in time, resulting in a decrease in tea quality.

[0005] This invention is implemented as follows: a tilting and discharging structure for tea processing includes a conveyor, a vibrating plate, a support rod, a mounting platform, a drive mechanism, an arc-shaped guide plate, a fixing rod, a height adjustment mechanism, and a ventilation assembly. These components work together to complete the tilting, buffering, diversion, dispersion, cooling, and conveying of the tea leaves. The specific structure is as follows:

[0006] 1. Conveyor Structure

[0007] The conveyor includes a base, a first servo motor, a conveyor belt, air vents, and drive rollers. The base serves as the installation foundation for the entire conveyor, supporting all components. Two drive rollers are rotatably mounted on the base, with the conveyor belt driving between them. The conveyor belt transports the dispersed and cooled tea leaves. The first servo motor is fixedly mounted on the side of the base, and its output shaft is fixedly connected to one end of a drive roller to drive the roller's rotation, thereby moving the conveyor belt. Several air vents are provided on the conveyor belt to cooperate with the ventilation assembly for rapid cooling of the tea leaves.

[0008] 2. Vibrating plate and supporting structure

[0009] A support rod is fixedly connected to the side of the conveyor (the side of the platform), and the end of the support rod is provided with a spherical groove. A spherical joint is fixedly connected to the bottom of the vibrating plate, and the spherical joint is installed in conjunction with the spherical groove, so that the vibrating plate can rotate flexibly around the support rod. The vibrating plate is inclined, and the bottom end of the vibrating plate extends above one end of the conveyor to guide the dispersed tea leaves to the conveyor. The vibrating plate is provided with several protrusions, which are arc-shaped protrusions and perpendicular to the direction of movement of the tea leaves. The spacing between the protrusions gradually decreases along the direction of movement of the tea leaves to achieve layered dispersion of the tea leaves and accelerate heat dissipation.

[0010] 3. Mounting platform and drive mechanism

[0011] A mounting platform is provided on the side of the conveyor. The mounting platform is used to install components such as the drive mechanism and the height adjustment mechanism. The drive mechanism is installed on the mounting platform. One end of the drive mechanism is connected to the bottom of the vibrating plate and is used to drive the vibrating plate to swing back and forth around the support rod so as to gradually throw the tea leaves on the vibrating plate onto the conveyor.

[0012] The drive mechanism includes a column, a slide rail, a rotating seat, a rocker arm, a support rod, a slider, a power mechanism, and an angle adjustment mechanism, with the specific structure as follows:

[0013] (1) Column and rotating seat: The column is fixedly installed on the mounting platform, and a rotating seat is rotatably installed on the top of the column. The rotating seat is used to support the rocker arm and realize its rotation;

[0014] (2) Rocker and support rod: A rocker is installed on the rotating seat, and a support rod is hinged to one end of the rocker. The support rod is perpendicular to the bottom surface of the vibrating plate and is used to support the vibrating plate and drive it to swing. The slide rail is fixedly installed at the bottom of the vibrating plate, and a slider is slidably installed in the slide rail. The support rod is rotatably installed on the slider so that the support rod can slide flexibly with the swing and angle adjustment of the vibrating plate.

[0015] (3) Power mechanism: A power mechanism is also installed on the mounting platform. The power mechanism and the support rod are located on both sides of the column. The power mechanism is used to drive the rocker arm to swing back and forth around the column. The power mechanism includes a second servo motor, a turntable, and a lever. The second servo motor is fixedly installed on the mounting platform. The output shaft of the second servo motor is fixedly connected to the turntable. The top of the turntable is eccentrically fixed with a lever. The rocker arm has a slot for the lever to pass through. The lever slides in the slot and drives the rocker arm to swing back and forth.

[0016] (4) Angle adjustment mechanism: The drive mechanism also includes an angle adjustment mechanism for adjusting the tilt angle of the vibrating plate to adapt to the processing of different types of tea. The angle adjustment mechanism includes a telescopic rod, an arc-shaped guide rod and a sliding sleeve. The arc-shaped guide rod is fixedly installed on the rocker arm. The axis of the arc-shaped guide rod coincides with the axis of the column. The sliding sleeve is slidably installed on the arc-shaped guide rod. The telescopic rod is hinged to the mounting platform. The movable end of the telescopic rod is hinged to the bottom of the sliding sleeve. When the movable end of the telescopic rod extends or shortens, it drives the rocker arm to rotate around the rotating seat, and then drives one end of the vibrating plate to rise and fall around the support rod through the support rod, thereby realizing the tilt angle adjustment without interfering with the reciprocating swing of the rocker arm.

[0017] 4. Arc-shaped guide plate and flow diversion structure

[0018] An arc-shaped guide plate is fixedly connected to the side of the mounting platform by a fixing rod. One end of the arc-shaped guide plate extends above the top of the vibrating plate, and its top end is placed below the discharge port of the stir-frying machine. It is used to receive the tea leaves poured out by the stir-frying machine and to buffer and guide them. A diversion structure is provided on the upper surface of the arc-shaped guide plate to disperse the concentrated falling tea leaves and initially solve the problem of concentrated falling points.

[0019] The diversion structure comprises three rows of structures from the end closest to the stir-fry machine to the end closest to the vibrating plate:

[0020] (1) First row: coarse diversion ribs, used to divide the tea ball into several streams on the left and right to achieve initial diversion;

[0021] (2) Second row: staggered subdivided flow teeth, used to break up large clumps of tea leaves and further disperse the tea leaves;

[0022] (3) Third row: flexible comb teeth, used to evenly distribute tea leaves to the width of the lower vibrating plate, ensuring that each area of ​​the vibrating plate can bear tea leaves;

[0023] To prevent tea leaves from getting stuck between the flow dividers, a vibration motor is also fixedly installed on the side of the arc-shaped guide plate. The vibration causes the tea leaves stuck in the flow dividers to fall off, ensuring smooth discharge.

[0024] The coarse diversion ribs, staggered fine diversion teeth, and flexible comb teeth are all made of fixed stainless steel round-head ribs or food-grade silicone flexible material, which ensures the diversion effect and avoids scratching the tea leaves.

[0025] 5. Height adjustment mechanism

[0026] The mounting platform is also equipped with a height adjustment mechanism for adjusting the height of the arc-shaped guide plate to match the angle adjustment of the vibrating plate, preventing the tea leaves from falling too far and breaking. The height adjustment mechanism includes a third servo motor, a threaded block, and a screw. The third servo motor is fixedly mounted on the mounting platform, the threaded block is slidably mounted on the mounting platform, one end of the fixing rod is fixedly connected to the threaded block, and the output shaft of the third servo motor is fixedly mounted with the screw, which is threadedly connected to the threaded block. The third servo motor drives the screw to rotate, causing the threaded block to rise and fall, which in turn causes the arc-shaped guide plate to rise and fall through the fixing rod, adjusting the distance between the vibrating plate and the arc-shaped guide plate, making the tea leaves fall more gently.

[0027] 6. Ventilation components

[0028] To achieve rapid cooling of the tea leaves, a ventilation assembly is also installed on the conveyor. The ventilation assembly includes an air-collecting hood, an air extraction pipe, and an air pump. The air pump is installed on the side of the conveyor, the air extraction pipe is connected to the air inlet of the air pump, and the air-collecting hood is fixedly connected to one end of the air extraction pipe. The upper surface of the air-collecting hood is in contact with the bottom of the upper conveyor belt of the conveyor. During operation, the air pump draws air from the air-collecting hood to create a negative pressure. Cold air from the outside enters the air-collecting hood through the air holes on the conveyor belt and carries away heat as it flows over the tea leaves, thus achieving rapid cooling of the tea leaves.

[0029] In addition, a filter device can be installed in the middle of the air extraction pipe to filter tea leaves, prevent tea leaves from entering the air extraction pump, and extend the service life of the equipment.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. Solve the problem of tea leaves gathering and becoming stuffy, and improve tea quality: Through the buffering of the arc-shaped guide plate and the initial dispersion of the diversion structure, combined with the reciprocating oscillation of the vibrating plate and the layering separation of the convex strips, the tea leaves are quickly dispersed after being stir-fried, preventing the heat of the inner tea leaves from not being able to dissipate, effectively preventing the tea leaves from developing a watery taste, darkening and yellowing of the leaf color, and ensuring the color, aroma and taste of the tea.

[0032] 2. Achieve rapid cooling of tea leaves and improve cooling efficiency: The vibrating plate disperses the tea leaves and guides them to the conveyor. The air holes on the conveyor belt, together with the exhaust components, form a negative pressure airflow. The cold air flows over the surface of the tea leaves and quickly removes the heat from the tea leaves. Compared with natural cooling, the cooling efficiency is greatly improved, which meets the needs of continuous production and avoids the subsequent accumulation of tea leaves that affects heat dissipation.

[0033] 3. Adaptable to different types of tea processing, highly flexible: The angle adjustment mechanism in the drive mechanism can flexibly adjust the tilt angle of the vibrating plate, and adjust the tea falling rate for teas of different volumes, weights and moisture contents to avoid untimely discharge or excessive falling; the height adjustment mechanism adjusts the height of the arc-shaped guide plate in sync, adapting to changes in the angle of the vibrating plate, and is highly versatile.

[0034] 4. Protect the appearance of tea leaves and reduce breakage: The cushioning effect of the arc-shaped guide plate, the flexible contact of the flexible comb teeth, and the height adjustment mechanism to control the distance of tea leaves falling effectively prevent tea leaves from breaking or buds due to impact and squeezing, thereby improving the appearance and commercial value of tea leaves.

[0035] 5. Achieve automated material discharge, reduce costs and ensure safety: The entire material discharge process requires no manual assistance. Through the coordinated work of various servo motors, vibration motors and air pumps, automatic buffering, diversion, dispersion, cooling and conveying are achieved. This not only reduces labor costs, but also avoids safety hazards such as burns caused by manual contact with high-temperature tea leaves and equipment, which is in line with the development trend of automation and safety in tea processing.

[0036] 6. Stable structure and reliable operation: The components are reasonably connected. The cooperation between the spherical joint and the spherical groove allows the vibrating plate to swing flexibly. The angle adjustment mechanism and the power mechanism do not interfere with each other. The vibration motor prevents tea leaves from getting stuck. The filter device protects the air pump. The overall structure is stable, has a low failure rate, is easy to maintain, and can adapt to large-scale tea processing scenarios for a long time. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0044] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0045] like Figures 1-5 As shown, this invention provides a tilting and discharging structure for tea processing, including a conveyor and a vibrating plate 7. A support rod 6 is fixedly connected to the side of the conveyor, and a spherical groove is provided at the end of the support rod 6. A spherical section 14 is fixedly connected to the bottom of the vibrating plate 7. The spherical section 14 is installed in conjunction with the spherical groove. The vibrating plate 7 is inclined, and the bottom end of the vibrating plate 7 extends above one end of the conveyor. Several protrusions 12 are provided on the vibrating plate 7.

[0046] A mounting platform 9 is provided on the side of the conveyor, and a drive mechanism 8 is installed on the mounting platform 9. One end of the drive mechanism 8 is connected to the bottom of the vibrating plate 7. The drive mechanism 8 is used to drive the vibrating plate 7 to swing back and forth around the support rod 6 so as to gradually throw the tea leaves on the vibrating plate 7 onto the conveyor.

[0047] The side of the mounting platform 9 is also fixedly connected to an arc-shaped guide plate 11 by a fixing rod 10. One end of the arc-shaped guide plate 11 extends above the top of the vibrating plate 7. The top of the arc-shaped guide plate 11 is placed below the discharge port of the stir-frying machine. After the stir-frying machine pours the tea leaves onto the arc-shaped guide plate 11, the arc-shaped guide plate 11 buffers the tea leaves and sends them to the vibrating plate 7. The drive mechanism 8 drives the vibrating plate 7 to swing back and forth. Under the action of inertia, the gathered tea leaves gradually separate on the vibrating plate 7, thereby quickly separating the tea leaves and preventing the heat of the inner tea leaves from not dissipating due to the gathering of tea leaves. This would cause the tea leaves to continue to be hot and humid, producing a musty taste, and causing the leaves to darken and turn yellow. The vibrating plate 7 will drive the tea leaves to gradually slide towards the conveyor, and the conveyor will further cool the tea leaves. Finally, the dispersed tea leaves can be collected.

[0048] Specifically, the protrusion 12 is an arc-shaped protrusion perpendicular to the direction of tea leaf movement. When the tea leaves slide on the protrusion 12, the bottom layer of tea leaves will be blocked by the protrusion 12, while the top layer of tea leaves will slide down, thus separating the tea leaves into layers. After the top layer of tea leaves slides down, without the pressure of the top layer of tea leaves, the bottom layer of tea leaves will also slide down over the protrusion 12. Therefore, the tea leaves piled together will be gradually separated by several protrusions 12, allowing the tea leaves to come into contact with the outside cold air, which can accelerate the dissipation of heat from the tea leaves. After the tea leaves fall onto the conveyor, they will be transported away by the moving conveyor, and subsequent tea leaves will not fall onto the tea leaves in front, thus allowing the tea leaves to cool down quickly.

[0049] The present invention provides a tilting and discharging structure for tea stir-frying processing. In this embodiment, the spacing between the plurality of protrusions 12 gradually decreases along the direction of tea movement.

[0050] As soon as the tea leaves fall onto the vibrating plate 7, the raised strips 12 provide little resistance to the tea leaves, allowing the piled-up tea leaves to slide off quickly and be separated by the raised strips 12. As the tea leaves slide off, they are gradually separated in the dense area of ​​the raised strips 12 and quickly spread out, thus allowing the tea leaves to dissipate heat in time.

[0051] This invention provides a tilting and discharging structure for tea leaf stir-frying. In this embodiment, the driving mechanism 8 includes a column 86 and a slide rail 812. The column 86 is fixedly installed on the mounting platform 9. A rotating seat 85 is rotatably installed on the top of the column 86. A rocker arm 87 is installed on the rotating seat 85. One end of the rocker arm 87 is hinged to a support rod 811. The slide rail 812 is fixedly installed on the bottom of the vibrating plate 7. A slider 813 is slidably installed inside the slide rail 812. The support rod 811 is rotatably installed on the slider 813. A power mechanism is also installed on the mounting platform 9. One end of the power mechanism is connected to the end of the rocker arm 87 away from the support rod 811. The power mechanism is used to drive the rocker arm 87 to swing back and forth around the column 86.

[0052] Specifically, if the support rod 811 is perpendicular to the bottom surface of the vibrating plate 7, then the support rod 811 can support the bottom of the vibrating plate 7 and keep the vibrating plate 7 in an inclined state.

[0053] The power mechanism and the support rod 811 are located on both sides of the column 86.

[0054] When in operation, the power mechanism is started, which drives one end of the rocker arm 87 to swing back and forth. The rocker arm 87 drives the support rod 811 to swing back and forth. The support rod 811 drives the vibrating plate 7 to swing back and forth around the support rod 6 through the slider 813. Under the action of inertia, the tea leaves slide obliquely downward relative to the surface of the vibrating plate 7, which can gradually shake the tea leaves onto the conveyor.

[0055] The present invention provides a tilting and discharging structure for tea stir-frying processing. In this embodiment, the power mechanism includes a second servo motor 84, which is fixedly installed on the mounting platform 9. The output shaft of the second servo motor 84 is fixedly connected to a turntable 82. A lever 83 is eccentrically fixed to the top of the turntable 82. A slot 81 is provided on the rocker arm 87 for the lever 83 to pass through.

[0056] Specifically, the second servo motor 84 is started, and the second servo motor 84 drives the lever 83 to rotate through the turntable 82. The lever 83 drives the rocker arm 87 to swing back and forth. The lever 83 slides in the slot 81, which can drive the vibrating plate 7 to swing back and forth.

[0057] This invention provides a tilting and discharging structure for tea processing. When frying different types of tea, the different sizes and degrees of frying result in different moisture contents and weights. If a vibrating plate 7 with the same inclination is used to guide the tea, the rate at which the tea slides off the vibrating plate 7 will vary, potentially leading to untimely discharge and accumulation of tea on the vibrating plate 7. Therefore, in this embodiment, the driving mechanism 8 further includes an angle adjustment mechanism. The angle adjustment mechanism is mounted on a mounting platform 9, and its output end is mounted on a rocker arm 87. The rocker arm 87 is rotatably mounted between a rocker arm 87 and a rotating seat 85. The angle adjustment mechanism drives the rocker arm 87 to rotate around the rotating seat 85. The rotating seat 85, through a support rod 811, drives one end of the vibrating plate 7 to rise and fall around a support rod 6, thereby adjusting the angle of the vibrating plate 7 to suit different types of tea processing.

[0058] Specifically, when the weight of the tea leaves after stir-frying is relatively small, increasing the inclination of the vibrating plate 7 will increase the weight component of the tea leaves along the surface of the vibrating plate 7, allowing the tea leaves to disperse on the vibrating plate 7 at a greater rate, thus enabling the tea leaves to disperse in a timely manner.

[0059] The present invention provides a tilting and discharging structure for tea stir-frying processing. In this embodiment, the angle adjustment mechanism includes a telescopic rod 88, an arc-shaped guide rod 810, and a sliding sleeve 89. The arc-shaped guide rod 810 is fixedly installed on a rocker arm 87. The axis of the arc-shaped guide rod 810 coincides with the axis of the column 86. The sliding sleeve 89 is slidably installed on the arc-shaped guide rod 810. The telescopic rod 88 is hinged to the mounting platform 9, and the movable end of the telescopic rod 88 is hinged to the bottom of the sliding sleeve 89.

[0060] Specifically, when adjusting the angle, the movable end of the telescopic rod 88 extends or shortens to drive the rocker arm 87 to rotate. The rocker arm 87 drives the vibrating plate 7 to rotate through the support rod 811. During operation, the power mechanism drives the rocker arm 87 to swing, and the rocker arm 87 drives the arc-shaped guide rod 810 to swing. The telescopic rod 88 will drive the sliding sleeve 89 to stay in the original position. The sliding sleeve 89 slides between the sliding sleeve 89 and the arc-shaped guide rod 810, so that the angle adjustment mechanism does not interfere with the movement of the rocker arm 87.

[0061] The present invention provides a tilting and discharging structure for tea stir-frying processing. In this embodiment, the upper surface of the arc-shaped guide plate 11 is provided with a diversion structure, which includes:

[0062] First row (the end closest to the stir-fry machine): Coarse diverting ribs 17, which divide the tea ball into several strands on the left and right;

[0063] The second row (located in the middle of the arc-shaped guide plate 11): staggered subdivided flow teeth 18, which can break up large clumps of tea leaves;

[0064] The third row (near the vibrating plate 7): flexible comb teeth 19, which evenly distribute the tea leaves across the width of the lower vibrating plate 7.

[0065] To prevent tea leaves from getting stuck between the flow dividers, a vibration motor 15 is also fixedly installed on the side of the 11.

[0066] Specifically, the coarse diversion ribs 17, the staggered subdivision ribs 18, and the flexible comb teeth 19 can all be made of fixed stainless steel round-head ribs or ribs made of food-grade silicone flexible material.

[0067] After the tea leaves are processed through a diversion structure, they can be distributed from a concentrated bundle to a wide, scattered pattern, thus initially solving the problem of "concentrated drop points".

[0068] The present invention provides a tilting and discharging structure for tea processing. After the tilt of the vibrating plate 7 is adjusted, the distance between the end of the vibrating plate 7 and the bottom of the arc-shaped guide plate 11 will also change. A larger drop distance will cause the tea leaves to hit the vibrating plate 7 heavily, which will easily break the tea leaves. Therefore, in this embodiment, a height adjustment mechanism 16 is also installed on the mounting platform 9. The height adjustment mechanism 16 includes a third servo motor 163, a threaded block 162 and a screw 161. The third servo motor 163 is fixedly installed on the mounting platform 9, the threaded block 162 is slidably installed on the mounting platform 9, one end of the fixing rod 10 is fixedly connected to the threaded block 162, and the output shaft of the third servo motor 163 is fixedly installed with the screw 161. The screw 161 is threadedly connected to the threaded block 162.

[0069] When the tilt of the vibrating plate 7 is adjusted, the third servo motor 163 is started. The third servo motor 163 drives the threaded block 162 to rise and fall through the screw 161. The threaded block 162 drives the arc-shaped guide plate 11 to rise and fall through the fixed rod 10, so as to adjust the distance between the vibrating plate 7 and the arc-shaped guide plate 11, so that the tea leaves fall more gently and better protect the tea leaves.

[0070] This invention provides a tilting and discharging structure for tea processing. To achieve rapid cooling and ripening of the tea, in this embodiment, the conveyor is also equipped with an exhaust assembly 5. The exhaust assembly 5 includes an air-gathering hood 51, an exhaust pipe 52, and an exhaust pump 53. The exhaust pump 53 is installed on the side of the conveyor, the exhaust pipe 52 is connected to the air inlet of the exhaust pump 53, the air-gathering hood 51 is fixedly connected to one end of the exhaust pipe 52, and the upper surface of the air-gathering hood 51 is in contact with the bottom of the upper conveyor belt 3 of the conveyor. The conveyor belt 3 is also provided with several air holes 4.

[0071] Specifically, when the tea leaves are being transported on the conveyor, the air pump 53 is activated. The air pump 53 draws air from the air collector 51, creating a negative pressure inside the air collector 51. Outside air enters the air collector 51 through the air hole 4. When the cold outside air flows over the tea leaves on the conveyor belt 3, the cold air carries away the heat from the tea leaves, causing the tea leaves to cool down quickly.

[0072] In addition, a filter device can be installed in the middle of the air extraction pipe 52 to filter the tea leaves and prevent them from entering the air extraction pump 53.

[0073] The conveyor includes a base 1, a support rod 6 fixedly installed on the side of the base 1, two drive rollers 13 rotatably installed on the base 1, a conveyor belt 3 is installed between the two drive rollers 13, a first servo motor 2 is fixedly installed on the side of the base 1, and the output shaft of the first servo motor 2 is fixedly connected to one end of a drive roller 13.

[0074] Workflow:

[0075] This invention achieves fully automated operation without the need for manual assistance:

[0076] 1. Equipment Debugging: Based on the type, volume, weight, and degree of stir-frying of the tea leaves to be processed, adjust the tilt angle of the vibrating plate 7 using the angle adjustment mechanism. Activate the telescopic rod 88, which extends or shortens, causing the rocker arm 87 to rotate around the rotating seat 85. This, in turn, causes one end of the vibrating plate 7 to rise and fall around the support rod 6 via the support rod 811, until a suitable tilt angle is achieved (e.g., 35°-40° for light tea leaves, 25°-30° for heavy tea leaves). Simultaneously activate the height adjustment mechanism 16, which in turn activates the third servo motor 163. The third servo motor 163 drives the screw 161 to rotate, causing the threaded block 162 to rise and fall. This, in turn, causes the arc-shaped guide plate 11 to rise and fall via the fixed rod 10. Adjust the distance between the vibrating plate 7 and the arc-shaped guide plate 11 to control the tea leaf drop distance to 50-100mm, preventing tea leaf breakage.

[0077] 2. Equipment Start-up: Start the first servo motor 2, the second servo motor 84, the vibration motor 15, and the air pump 53 respectively. The first servo motor 2 drives the transmission roller 13 to rotate, causing the conveyor belt 3 to move at a uniform speed (speed adjustment is 0.5-1m / s); the second servo motor 84 drives the turntable 82 to rotate, and the turntable 82 drives the eccentrically fixed lever 83 to rotate. The lever 83 slides in the slot 81 of the rocker arm 87, causing the rocker arm 87 to swing back and forth around the column 86. The rocker arm 87 drives the vibrating plate 7 to swing back and forth around the support rod 6 through the support rod 811 and the slider 813; the vibration motor 15 drives the arc-shaped guide plate 11 to vibrate slightly to prevent tea leaves from getting stuck between the diversion structures; the air pump 53 starts, drawing air from the air collector 51 to form a negative pressure. Outside cold air enters the air collector 51 through the air holes 4 on the conveyor belt 3, forming a stable airflow.

[0078] 3. Tea pouring and buffering: The top of the arc-shaped guide plate 11 is placed below the discharge port of the stir-frying machine. The stir-frying machine pours the stir-fried tea onto the arc-shaped guide plate 11. The arc-shaped guide plate 11 acts as a buffer for the hot tea, preventing the tea from being directly impacted and broken. The tea slides down the arc-shaped guide plate 11 and passes through the coarse diverting ribs 17, the staggered fine diverting teeth 18, and the flexible comb teeth 19 in sequence. The coarse diverting ribs 17 divide the concentrated tea clumps into multiple strands on the left and right. The staggered fine diverting teeth 18 break up the large clumps of tea. The flexible comb teeth 19 evenly distribute the tea in the width direction of the vibrating plate 7, achieving the initial dispersion of the tea.

[0079] 4. Tea Dispersion and Heat Dissipation: After initial dispersion, the tea leaves fall onto the inclined vibrating plate 7. Driven by the driving mechanism 8, the vibrating plate 7 swings back and forth. Due to inertia, the tea leaves slide diagonally downward relative to the surface of the vibrating plate 7. At the same time, the arc-shaped protrusions 12 on the vibrating plate 7 act as a barrier and layering agent for the tea leaves. The bottom layer of tea leaves is blocked by the protrusions 12, while the top layer slides down. After the top layer of tea leaves slides down, the bottom layer continues to slide down over the protrusions 12 without pressure. The spacing between the protrusions 12 gradually decreases along the direction of tea leaf movement, so that the tea leaves are gradually and thoroughly dispersed and spread out during the sliding process, making full contact with the outside cold air and accelerating heat dissipation.

[0080] 5. Tea Cooling and Conveying: The dispersed tea leaves slide from the bottom of the vibrating plate 7 onto the conveyor belt 3 of the conveyor. The conveyor belt 3 moves at a constant speed, conveying the tea leaves forward. At the same time, the negative pressure airflow generated by the exhaust component 5 flows downward through the air holes 4 on the conveyor belt 3, passing over the surface of the tea leaves and quickly removing the remaining heat from the tea leaves, thus achieving rapid cooling of the tea leaves. During the cooling process, the tea leaves are continuously conveyed by the conveyor belt 3, and subsequent tea leaves will not accumulate on top of the previous tea leaves, ensuring uniform cooling effect.

[0081] 6. Tea Collection and Equipment Shutdown: After cooling, the tea leaves are conveyed to the end by conveyor belt 3 for centralized collection. After processing, the vacuum pump 53, vibration motor 15, second servo motor 84, first servo motor 2 and third servo motor 163 are turned off in sequence. The tea leaves on the surface of the equipment are cleaned, and the components are checked to ensure they are in good working order for the next use.

[0082] In addition, during the processing, the air volume of the air pump can be adjusted according to the cooling effect of the tea leaves; the oscillation frequency of the vibrating plate can be adjusted according to the dispersion of the tea leaves; and the movement speed of the conveyor belt can be adjusted according to the discharge speed to ensure that the equipment is always in the best working condition and can adapt to the processing needs of different tea leaves.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0084] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
