Fixation machine and tea processing equipment

Abstract

This invention provides a tea fixing machine and tea processing equipment. A pot is mounted on a frame, and a turning mechanism is rotatably mounted on the frame above the pot. A lifting mechanism is also mounted on the frame below the pot. One side of the pot is hinged to the frame, and the lifting mechanism abuts or connects to the other side of the pot. During operation, the lifting mechanism simply lifts the pot upwards, raising it a suitable distance towards the turning mechanism based on the amount of tea leaves in the pot. The turning mechanism then gently presses the tea leaves in the pot during the tea-frying process, causing the softened tea leaves to be quickly flattened and shaped under external force. This shortens the tea fixing and frying time, avoids excessively long fixing and frying times, and improves the efficiency and quality of tea fixing.

Description

Technical Field

[0001] This invention belongs to the technical field of tea-making tools, and in particular, relates to a fixation machine and tea processing equipment. Background Technology

[0002] The processing of green tea, such as Longjing, typically involves two steps: the initial pan-frying and the final pan-frying. The initial pan-frying primarily involves fixing the green tea leaves and initial shaping, while the final pan-frying further shapes and dries the leaves. Currently, in the fixing process of green tea, the pan rotates with the shaft to turn the tea leaves, but it cannot press the leaves appropriately during the turning process. This prevents the softened tea leaves from being quickly flattened and shaped under external force (to bring the tea closer to its final shape), resulting in excessively long fixing and frying times, which is detrimental to improving the efficiency and quality of tea processing. Summary of the Invention

[0003] Based on the aforementioned problems in the prior art, one of the objectives of this invention is to provide a fixation machine to solve the problem that in the prior art, green tea and other tea leaves cannot be properly pressed during the fixation process, and the softened tea leaves cannot be quickly flattened and shaped under external force.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a blanching machine, comprising:

[0005] frame;

[0006] The pot body is mounted on the frame;

[0007] A heater for heating the pot body;

[0008] A stirring mechanism for stirring tea leaves in the pot, the stirring mechanism being rotatably mounted on the frame, positioned above the pot, and at least a portion extending into the pot; and

[0009] A lifting mechanism is mounted on the frame and is located below the pot body;

[0010] One side of the pot is hinged to the frame, and the lifting mechanism abuts against or is connected to the other side of the pot, so that when the lifting mechanism lifts the pot upward, the pot is lifted toward the turning mechanism, so that the turning mechanism appropriately presses the tea leaves in the pot during the tea-stirring process.

[0011] Furthermore, the tea-fixing machine also includes a pressure sensor for detecting the pressure applied to the tea leaves in the pot by the turning mechanism and a controller for controlling the operation of the lifting mechanism based on the pressure detected by the pressure sensor.

The tea-killing machine also includes a drive mechanism that is pulverically connected to the rotating shaft. When the drive mechanism drives the rotating shaft to rotate, the rotating shaft can drive the scraper assembly to turn around the rotating shaft, so that the scraper assembly can turn over and throw up the tea leaves in the pot body.

[0014] Furthermore, the lifting mechanism includes a strip-shaped or columnar lifting member that can be movably mounted on the frame, a gear component for driving the lifting member to move up and down, and a drive motor for driving the gear to rotate. The lifting member is provided with a second tooth that meshes with the first tooth of the gear component, and the top end of the lifting member is provided with a tray for abutting against the pot body.

[0015] Furthermore, the number of lifting components is set to at least two, the number of gear components is consistent with the number of lifting components, the lifting mechanism also includes a drive shaft rotatably mounted on the frame, the gear components are mounted on the drive shaft, and the motor shaft of the drive motor is connected to the drive shaft.

[0016] Furthermore, the tea-killing machine also includes a protective cover covering the mouth of the pot, and the protective cover is provided with an observation port for observing the tea leaves in the pot.

[0017] Furthermore, the protective cover is provided with a discharge port, which is located at a position higher than the opening of the pot body.

[0018] Furthermore, the blanching machine also includes a movable door assembly for selectively opening or closing the discharge port, the movable door assembly being disposed on the protective cover at a position corresponding to the discharge port.

[0019] Based on the aforementioned problems in the prior art, the second objective of this invention is to provide a tea processing device having a fixing machine as described in any of the above solutions.

[0020] To achieve the above objectives, the technical solution adopted by the present invention is to provide a tea processing equipment, including the fixation machine provided by any of the above solutions.

[0022] The tea-processing equipment and tea-fixing machine of this invention have the following structure: a pot is mounted on a frame, and a turning mechanism is rotatably mounted on the frame above the pot. A lifting mechanism is also mounted on the frame below the pot. One side of the pot is hinged to the frame, and the lifting mechanism abuts or connects to the other side of the pot. When the tea-fixing machine is working, the lifting mechanism simply lifts the pot upwards, raising it a suitable distance towards the turning mechanism based on the amount of tea leaves in the pot. The turning mechanism then moderately presses the tea leaves in the pot during the tea-frying process, causing the softened tea leaves to be quickly flattened and shaped under external force. This helps to shorten the tea-fixing and frying time, avoids excessively long processing times, and improves the efficiency and quality of tea-fixing. Attached Figure Description

[0047] Please refer to the following: Figures 1 to 11 The fixing machine provided in the embodiments of the present invention will now be described. The fixing machine provided in the embodiments of the present invention is applicable to tea processing equipment. Please refer to further details. Figure 1 , Figure 2 and Figure 3The tea-fixing machine provided in this embodiment of the invention includes a frame 1, a pot body 2, a heater, a turning mechanism 3, and a lifting mechanism 4. One side of the pot body 2 is rotatably mounted on the frame 1 via a rotating shaft 20. A heater is provided on the pot body 2 and / or the frame 1. When the heater is energized, it heats the pot body 2, bringing it to the temperature (200°C to 300°C) suitable for fixing fresh tea leaves. The pot body 2 is a horizontally arranged semi-circular trough-type pot body. The turning mechanism 3 is used to turn the tea leaves in the pot body 2, thus solving the problems of insufficient fixing at 200°C and the need for a long frying time, as well as the high energy consumption at 300°C. This effectively shortens the tea-fixing time and improves the efficiency of tea-fixing. Specifically, the turning mechanism 3 is rotatably mounted on the frame 1, located above the pot body 2, and at least a portion of the turning mechanism 3 extends into the pot body 2. The temperature inside the pot body 2 is controlled between 200°C and 250°C. A lifting mechanism 4 is also provided on the frame 1 below the pot body 2. One side of the pot body 2 is hinged to the frame 1, and the lifting mechanism 4 abuts or connects to the other side of the pot body 2. When the lifting mechanism 4 lifts the pot body 2 upward, the pot body 2 can be lifted a suitable distance toward the turning mechanism 3 according to the amount of tea leaves in the pot body 2. This allows the turning mechanism 3 to press the tea leaves in the pot body 2 appropriately during the tea-stirring process. As a result, the tea leaves in the pot body 2 that have softened due to heat are quickly flattened and shaped under external force (making the tea leaves closer to the shape of finished tea). This helps to shorten the tea-killing and stir-frying time, avoids excessively long tea-killing and stir-frying time, and improves the efficiency and processing quality of the tea.

[0048] The tea-fixing machine provided in this embodiment of the invention, compared with the prior art, features a pot body 2 mounted on a frame 1, with a turning mechanism 3 rotatably mounted on the frame 1 above the pot body 2, and a lifting mechanism 4 mounted on the frame 1 below the pot body 2. One side of the pot body 2 is hinged to the frame 1, and the lifting mechanism 4 abuts against or connects to the other side of the pot body 2. During operation, the lifting mechanism 4 simply lifts the pot body 2 upwards, raising it a suitable distance towards the turning mechanism 3 according to the amount of tea leaves in the pot body 2. The turning mechanism 3 can then moderately press the tea leaves in the pot body 2 during the tea-frying process, causing the softened tea leaves to be quickly flattened and shaped under external force. This helps to shorten the tea-fixing and frying time, avoids excessively long processing times, and improves the efficiency and quality of tea fixing.

[0049] Please refer to the following: Figure 1 and Figure 2In some embodiments, the tea-fixing machine also includes a pressure sensor 6 and a controller. The pressure sensor 6 is used to detect the pressure applied by the turning mechanism 3 to the tea leaves in the pot 2. The controller is used to control the operation of the lifting mechanism 4 based on the pressure detected by the pressure sensor 6. The controller is electrically connected to both the pressure sensor 6 and the lifting mechanism 4. Specifically, when the tea-fixing machine is working, the lifting mechanism 4 is used to lift the pot 2 upwards, raising it a suitable distance towards the turning mechanism 3 according to the amount of tea leaves in the pot 2. The pressure sensor 6 detects the pressure applied by the turning mechanism 3 to the tea leaves in the pot 2 in real time. When the pressure sensor 6 detects that the pressure applied by the turning mechanism 3 to the tea leaves in the pot 2 reaches a preset pressure value, the controller controls the lifting mechanism 4 to stop lifting the pot 2 upwards, so that the pressure applied by the turning mechanism 3 to the tea leaves in the pot 2 remains constant. Of course, the controller can also control the lifting mechanism 4 to lift the pot 2 upwards or move the pot 2 downwards, so that the turning mechanism 3 applies varying pressure to the tea leaves in the pot 2, allowing the turning mechanism 3 to apply appropriate pressure to the tea leaves according to a preset pressure curve during the tea-frying process. During the tea-stirring process, the turning mechanism 3 presses the tea leaves in the pot 2 appropriately, which allows the softened tea leaves in the pot 2 to be quickly flattened and shaped under external force. This helps to shorten the tea-killing and stir-frying time, avoids excessively long tea-killing and stir-frying time, and improves the efficiency and processing quality of tea.

[0050] Understandably, in some embodiments, the pressure sensor 6 can be located at the contact point or connection between the lifting mechanism 4 and the pot body 2. The pressure sensor 6 can detect the magnitude of the pressure applied by the turning mechanism 3 to the tea leaves in the pot body 2 by the reaction force of the pot body 2 on the lifting mechanism 4. For example, when the total pressure detected by the pressure sensor 6 is F1, the weight of the pot body 2 is G1, and the total weight of the tea leaves is G2, then the magnitude of the pressure applied by the turning mechanism 3 to the tea leaves in the pot body 2 is F = F1 - G1 - G2.

[0051] Please refer to the following: Figure 6 , Figure 8 and Figure 10In some embodiments, the turning mechanism 3 includes a rotating shaft 31 rotatably mounted on the pot body 2 and / or the frame 1, a scraper assembly 32 disposed in the pot body 2, and a connecting arm 33 fixedly connected to the rotating shaft 31. The fixing machine also includes a drive mechanism 36 driven by the rotating shaft 31. When the drive mechanism 36 drives the rotating shaft 31 to rotate, the rotating shaft 31 can drive the scraper assembly 32 to periodically rotate around the rotating shaft 31, so that the scraper assembly 32 can turn and scrape the tea leaves in the pot body 2. The scraped tea leaves are thrown up by the scraper assembly 32 to simulate the action of manually tossing leaves, realizing the continuous turning and stir-frying of the tea leaves. This not only reduces the accumulation of water vapor that causes yellowing, but also allows the tea leaves to lose water evenly during fixing, avoiding the excessive and rapid loss of chlorophyll in fresh tea leaves due to prolonged stir-frying, which would prevent the tea leaves from maintaining their green color and affect the quality and taste of the processed tea. It should be noted that the drive mechanism 36 can be, but should not be limited to, a geared motor.

[0052] Please refer to the following: Figure 1 , Figure 4 and Figure 5 In some embodiments, the lifting mechanism 4 includes a strip-shaped or columnar lifting member 41 movably mounted on the frame 1, a gear component 42 for driving the lifting member 41 to move up and down, and a drive motor 46 for driving the gear to rotate. The lifting member 41 has a second tooth 411 that meshes with the first tooth 421 of the gear component 42, and the top of the lifting member 41 is provided with a tray 43 for abutting against the pot body 2. In this embodiment, through the meshing of the first tooth 421 of the gear component 42 with the second tooth 411 on the lifting member 41, when the drive motor 46 drives the gear component 42 to rotate, the rotating gear component 42 can drive the lifting member 41 to move up and down, thereby lifting or lowering the pot body 2 through the lifting member 41. This allows the pot body 2 to be lifted a suitable distance toward the turning mechanism 3 according to the amount of tea leaves in the pot body 2, so that the turning mechanism 3 can apply appropriate pressure to the tea leaves in the pot body 2, and achieve the goal of the turning mechanism 3 to press the tea leaves appropriately as needed during the tea-stirring process.

[0053] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the top of the lifting member 41 is provided with a tray 43 for abutting against the pot body 2. By having the tray 43 contact the pot body 2, the contact area with the pot body 2 of the fixing machine can be increased, so that the lifting member 41, which moves up and down, can smoothly lift or lower the pot body 2. This allows the pot body 2 to adaptively adjust its position distance from the turning mechanism 3 according to the amount of tea leaves in the pot body 2, ensuring that the pot body 2 of the fixing machine is raised to a suitable distance toward the turning mechanism 3 of the fixing machine, so that the turning mechanism 3 can automatically press the tea leaves in the pot body 2 appropriately during the tea-stirring process.

[0054] Please refer to the following: Figure 1 , Figure 2 and Figure 3 In some embodiments, the lifting member 41 is an axially movable sliding shaft, and the lifting mechanism 4 further includes a sliding sleeve 44 for slidingly mounting the sliding shaft on the frame 1 of the tea-cooking machine. The top end of the sliding shaft abuts against the pot body 2, and a second tooth 411 is provided on the sliding shaft at the position corresponding to the gear component 42. In this embodiment, the sliding shaft is slidably mounted on the frame 1 of the tea-cooking machine by the sliding sleeve 44, and the sliding shaft is vertically arranged on the frame 1 of the tea-cooking machine. When the gear component 42 drives the sliding shaft to move along its axial direction, the pot body 2 can be lifted or lowered by the sliding shaft. This allows the pot body 2 to adaptively adjust its position distance from the turning mechanism 3 according to the amount of tea leaves in the pot body 2, ensuring that the pot body 2 of the tea-cooking machine is lifted a suitable distance toward the turning mechanism 3 of the tea-cooking machine, so that the turning mechanism 3 can automatically press the tea leaves in the pot body 2 appropriately during the tea-stirring process.

[0055] Understandably, in some other embodiments, the lifting member 41 is a rack that meshes with a gear. The rack is slidably mounted on the frame 1 of the fixing machine, and the top of the rack abuts against the pot body 2. In this embodiment, the rack is slidably mounted on the frame 1 of the fixing machine via a slide rail mechanism, and the rack is vertically mounted on the frame 1. When the gear component 42 drives the rack to move along its axial direction, it is only necessary to abut the top of the rack against the pot body 2. The rack can lift or lower the pot body 2, so that the pot body 2 can be adaptively adjusted according to the amount of tea leaves in the pot body 2 and its position distance from the turning mechanism 3. This ensures that the pot body 2 of the fixing machine is raised a suitable distance toward the turning mechanism 3 of the fixing machine, so that the turning mechanism 3 can automatically press the tea leaves in the pot body 2 appropriately during the tea-stirring process.

[0056] Understandably, in some other embodiments, a rack can also be fixedly installed on the lifting member 41 at the position corresponding to the gear member 42, and the rack is vertically installed on the lifting member 41 of the fixing machine. When the gear member 42 drives the rack to move along its axial direction, the top of the rack only needs to abut against the pot body 2, and the pot body 2 can be lifted or lowered by the rack. This allows the pot body 2 to adaptively adjust its position distance from the turning mechanism 3 according to the amount of tea in the pot body 2, ensuring that the pot body 2 of the fixing machine is raised to a suitable distance toward the turning mechanism 3 of the fixing machine, so that the turning mechanism 3 can automatically press the tea in the pot body 2 appropriately during the tea-stirring process.

[0057] Please refer to the following: Figure 2 and Figure 7In some embodiments, the number of lifting members 41 is set to at least two, and the number of gear components 42 is consistent with the number of lifting members 41. The lifting mechanism 4 also includes a drive shaft 45 rotatably mounted on the frame 1. The gear components 42 are mounted on the drive shaft 45, and the motor shaft of the drive motor 46 is connected to the drive shaft 45. The drive motor 46 drives the drive shaft 45 to rotate, and the drive shaft 45 drives at least two gear components 42 to rotate around the drive shaft 45. Since the first tooth 421 of each gear component 42 meshes with the second tooth 411 on the corresponding lifting member 41, the rotating gear component 42 can drive the lifting member 41 to move up and down, thereby driving the pot body 2 to be lifted or lowered stably and quickly through the lifting member 41. It can be understood that in some embodiments, the drive motor 46 is a geared motor, and a torque sensor is mounted on the motor shaft of the drive motor 46 through a coupling.

[0058] Please refer to the following: Figure 3 , Figure 4 and Figure 5 In some embodiments, the gear component 42 is a sector gear. By meshing the sector gear with the second tooth 411 on the corresponding lifting member 41, the rotating sector gear can drive the lifting member 41 to move up and down, thereby driving the pot body 2 to be raised or lowered stably and quickly through the lifting member 41.

[0059] Please refer to the following: Figure 1 and Figure 2 In some embodiments, a pressure sensor 6 is disposed on the lifting member 41 so that when the lifting member 41 lifts the pot body 2 of the fixing machine, the pressure sensor 6 can detect the amount of pressure applied to the tea leaves in the pot body 2 of the fixing machine by the turning mechanism 3 of the fixing machine.

[0060] Please refer to the following: Figure 3 , Figure 4 and Figure 8 In some embodiments, the fixation machine also includes a protective cover 7 covering the opening of the pot body 2. The protective cover 7 blocks the tea leaves, allowing the tea leaves thrown up by the turning mechanism to quickly fall back into the pot body 2, preventing them from being thrown out of the pot body 2. Furthermore, the protective cover 7 is provided with an observation port 8 for observing the tea leaves in the pot body 2, allowing the fixation status of the tea leaves to be observed through the observation port 8.

[0061] Please refer to the following: Figure 5 and Figure 8In some embodiments, the protective cover 7 is provided with a discharge port 9, which is located higher than the opening of the pot body 2. After the tea leaves in the pot body 2 have finished processing, the tilting mechanism can scrape the tea leaves from the pot body 2 to the discharge port 9. The tea leaves are then discharged from the discharge port 9 under inertia, achieving rapid discharge without tilting the pot body 2. To facilitate the rapid discharge of tea leaves from the discharge port 9, a guide ramp 30 is provided on the protective cover 7 at the position corresponding to the discharge port 9.

[0062] Please refer to the following: Figure 4 , Figure 5 and Figure 8 In some embodiments, the fixing machine further includes a movable door assembly 5 for selectively opening or closing the discharge port 9, the movable door assembly 5 being disposed on the protective cover 7 at a position corresponding to the discharge port 9. By disposing of the movable door assembly 5 on the protective cover 7 at the position corresponding to the discharge port 9, during the tea-stirring process by the flipping mechanism, the movable door assembly 5 closes the discharge port 9 to prevent the tea leaves from being thrown out of the discharge port 9 due to inertia. After the tea leaves in the pot 2 have finished fixing, the movable door assembly 5 opens the discharge port 9, and the flipping mechanism can scrape the tea leaves in the pot 2 onto the discharge port 9, where the tea leaves are discharged due to inertia.

[0063] Please refer to the following: Figure 8 In some embodiments, the movable door assembly 5 includes a rotating rod 51 rotatably mounted on the protective cover 7, a switch door 52 connected to the rotating rod 51, a drive arm 53 connected to the rotating rod 51, and a linear actuator 54 connected to the drive arm 53. The linear actuator 54 drives the rotating rod 51 to rotate, and the rotating rod 51 drives the switch door 52 to open or close the discharge port.

[0064] Please refer to the following: Figure 9 , Figure 10 and Figure 11In some embodiments, the scraper assembly 32 includes a flipping scraper 321, a lifting plate 322, and a tea-scraping plate 323. The flipping scraper 321 is rotatably mounted inside the pot body 2 via a rotating shaft 31. One side of the lifting plate 322 is connected to the flipping scraper 321, and the lifting plate 322 and the flipping scraper 321 are connected at an angle. When the flipping scraper 321 drives the lifting plate 322 to flip, the lifting plate 322 can slide along the inner wall of the pot body 2 and scoop up the tea leaves in the pot body 2, thereby breaking up and turning the tea leaves in the pot body 2. During the process of the lifting plate 322 turning the tea leaves, the tea leaves can be scraped up by the lifting plate 322. The scraped tea leaves are thrown back into the pot body 2 under the action of the continuously flipping flipping scraper 321, thus simulating the manual tea-throwing action of fixing the tea leaves by flipping the scraper assembly 322. Furthermore, the tea-shoveling plate 323 is connected to the suspended side of the scraper plate 322, meaning that the tea-shoveling plate 323 is located on the side of the scraper plate 322 opposite to the flipping scraper plate 321, and is positioned above the scraper plate 322. The tea-shoveling plate 323 and the scraper plate 322 are connected at an angle, allowing the tea-shoveling plate 323 to efficiently shovel up the clumps of tea leaves. This ensures that the clumps of tea leaves are thoroughly dispersed during the turning process, facilitating the even distribution of the tea leaves into the pot body 2 via the flipping scraper plate 321. This effectively simulates the manual tossing and fixing action of tea leaves through the flipping scraper assembly 32. In addition, the connection between the tea-shoveling plate 323 and the scraper plate 322 forms an arc-shaped transition surface, which prevents the scraper assembly 32 from scratching or breaking the tea leaves during the flipping process, thus ensuring the integrity of the tea leaves' shape. The flipping scraper plate 321, the scraper plate 322, and the tea-shoveling plate 323 together form a receiving groove for accommodating the tea leaves.

[0065] Please refer to the following: Figure 7 , Figure 10 and Figure 11In some embodiments, the scraper assembly 32 includes a flip scraper 321, a scraping plate 322, and a tea-scraping plate 323. The flip scraper 321 can be rotatably installed in the pot body 2 via a rotating shaft 31. One side of the scraping plate 322 is connected to the flip scraper 321, and the scraping plate 322 and the flip scraper 321 are connected at an angle. The tea-scraping plate 323 is connected to the side of the scraping plate 322 that is suspended, that is, the tea-scraping plate 323 is provided on the side of the scraping plate 322 away from the flip scraper 321, and the tea-scraping plate 323 is located above the scraping plate 322. The tea-scraping plate 323 and the scraping plate 322 are connected at an angle. When the tea-fixing machine is working, the lifting mechanism 4 is used to lift the pot body 2 upwards, so that the pot body 2 is lifted a suitable distance toward the turning mechanism 3 according to the amount of tea leaves in the pot body 2. During the tea-frying process, the tea-shoveling plate 323 and / or scraping plate 322 of the turning mechanism 3 can press the tea leaves in the pot body 2 appropriately, so that the tea leaves softened by heat in the pot body 2 are quickly flattened and shaped under the action of external force, which helps to shorten the tea-fixing and frying time, avoid the tea-fixing and frying time being too long, and improve the tea-fixing efficiency and processing quality.

[0066] Please refer to the following: Figure 7 , Figure 9 and Figure 11 In some embodiments, the angle between the scraper 322 and the flip scraper 321 is 90° to 135°, which allows the scraper 322 to flip and scrape the tea leaves, which then slide obliquely onto the flip scraper 321 and are then thrown into the pot body 2 by the continuously flipping flip scraper 321. This allows the flipping scraper assembly 32 to simulate the manual tea leaf throwing action of fixing.

[0067] Please refer to the following: Figure 7 , Figure 9 and Figure 10 In some embodiments, the included angle between the tea-shoveling plate 323 and the scraping plate 322 is 30° to 75°, which allows the tea-shoveling plate 323 to efficiently shovel the clumps of tea leaves, so that the clumps of tea leaves can be fully dispersed before being scraped, and the tea leaves can lose water efficiently and evenly to achieve fixation, thereby effectively avoiding the phenomenon of piling up and turning yellow during the fixation and frying process, which is conducive to improving the consistency of the fixation effect of tea leaves.

[0068] Please refer to the following: Figure 9 , Figure 10 and Figure 11In some embodiments, the scraper 322 is formed by bending one side of the flip scraper 321 upwards, which enhances the stability of the connection between the scraper 322 and the flip plate, and facilitates the smooth sliding of the tea leaves that are flipped and scraped by the scraper 322 onto the flip scraper 321, and then thrown into the pot body 2 by the continuously flipping flip scraper 321, thereby simulating the manual tea leaf throwing and withering action by the flipping scraper assembly 32.

[0069] Please refer to the following: Figure 9 , Figure 10 and Figure 11 In some embodiments, the tea-shoveling plate 323 is formed by bending the side of the scraper plate 322 that is suspended upwards, which enhances the stability of the connection between the tea-shoveling plate 323 and the scraper plate 322, and facilitates the tea-shoveling plate 323 to efficiently shovel and fully disperse the tea leaves that have gathered together.

[0070] Please refer to the following: Figure 9 , Figure 10 and Figure 11 In some embodiments, to facilitate the connection between the scraper assembly 32 and the rotating shaft 31 and to ensure the stability and reliability of the connection between the scraper assembly 32 and the rotating shaft 31, the flipping scraper 321 is provided with at least two connecting arms 33 on the side opposite to the scraping plate 322. Each connecting arm 33 includes a parallel arm fixedly connected to and parallel to the scraping plate 322, and a bent arm connected at an angle to the parallel arm. The bent arm has bolt holes 6 and abutment ears. Specifically, the connecting arm 33 is integrally formed with the flipping scraper 321. The flipping mechanism 3 also includes a clamp 10 fixedly sleeved on the rotating shaft 31 and a rotating arm 35 for fixing the connecting arm 33 to the clamp 10. The first end of the rotating arm 35 is fixedly connected to the clamp 10, and the second end of the rotating arm 35 is fixedly connected to the connecting arm 33 by bolts. In this embodiment, fixing the rotating arm 35 to the rotating shaft 31 by the clamp 10 enhances the stability of the connection between the rotating arm 35 and the rotating shaft 31 and facilitates the disassembly and replacement of the flipping scraper 321.

[0071] Please refer to the following: Figure 9 , Figure 10 and Figure 11In some embodiments, the rotating scraper 321 is provided with multiple discharge ports 34, which are used to allow the tea leaves on the rotating scraper 321 to fall back into the pot 2 of the tea fixing machine. When the rotating shaft 31 is driven to rotate by a drive mechanism 36 such as a servo motor, the rotating shaft 31 can drive the rotating scraper 321 to rotate periodically around the rotating shaft 31. In turn, the rotating scraper 321 drives the scraper plate 322 to turn and scrape the tea leaves in the pot 2. The scraped tea leaves are thrown back into the pot 2 by the continuously rotating rotating scraper 321, so that the scraper assembly 32 can simulate the action of manually throwing tea leaves to fix the tea. Furthermore, the tea leaves on the flip scraper 321 can be dispersed and fall back into the pot body 2 through multiple discharge ports 34, allowing the tea leaves to be loosely scattered into the pot body 2. This helps to improve the effect of the scraper assembly 32 in simulating the action of manually tossing tea leaves for fixing, thereby enabling the tea leaves to lose water more efficiently and evenly and achieve a good fixing effect.

[0072] Please refer to the following: Figure 9 , Figure 10 and Figure 11 In some embodiments, the flipping scraper 321 is rectangular, and multiple discharge ports 34 are arranged at intervals along the length of the scraper assembly 32. The distance between two adjacent discharge ports 34 is equal, so that the tea leaves scraped up by the flipping scraper 321 can fall back into the pot body 2 through the evenly distributed multiple discharge ports 34, so that the tea leaves can be fully and evenly scattered, thereby enabling the tea leaves to lose water more efficiently and evenly and achieve a good blanching effect.

[0073] Please refer to the following: Figure 9 , Figure 10 and Figure 11 In some embodiments, the discharge port 34 is a square opening, and the distance between two adjacent discharge ports 34 is equal to half the side length of the square opening. This facilitates the rapid flow of tea leaves from the rotating scraper 321 back into the pot body 2 through the discharge port 34, allowing the tea leaves to be fully and evenly dispersed. This enables the tea leaves to lose water more efficiently and evenly, achieving a good fixation effect. Furthermore, the portion between the two discharge ports 34 not only prevents tea leaves from accumulating on the rotating scraper 321 but also helps to disperse the tea leaves.

[0074] Please refer to the following: Figure 9 , Figure 10 and Figure 11In some embodiments, the rotating scraper 321 is provided with multiple discharge ports 34, which are used to allow the tea leaves on the rotating scraper 321 to fall back into the pot 2 of the tea fixing machine. When the rotating shaft 31 is driven to rotate by a drive mechanism 36 such as a servo motor, the rotating shaft 31 can drive the rotating scraper 321 to rotate periodically around the rotating shaft 31. In turn, the rotating scraper 321 drives the scraper plate 322 to turn and scrape the tea leaves in the pot 2. The scraped tea leaves are thrown back into the pot 2 by the continuously rotating rotating scraper 321, so that the scraper assembly 32 can simulate the action of manually throwing tea leaves to fix the tea.
