Description

Technical Field

[0001] The present invention relates to the technical field of tea processing. More specifically, the present invention relates to a device and process for preparing black tea. Background Art

[0002] Black tea is made from the young leaves or buds of the tea plant in the Camellia family, and is refined through a series of technological processes such as withering, rolling, fermentation, and drying. In the field of tea preparation and processing, as a fully fermented tea deeply loved by consumers, the processing technology and equipment level of black tea are directly related to the quality and taste of the tea. Among them, rolling is particularly important. In order to facilitate the staff to roll black tea, a rolling machine needs to be used.

[0003] Existing rolling machines are mostly composed of a rolling barrel, a rolling disc, a pressure unit, and a baffle, etc. The working principle is as follows: First, pour the black tea to be rolled into the inside of the rolling barrel, and then start the pressure unit to increase the pressure of the black tea inside the rolling barrel to facilitate the rapid shaping of the tea leaves. The rolling barrel drives the black tea to rub against the rolling disc to break the cell walls of the tea leaves, causing the tea juice to overflow, and physically shaping the tea leaves into a curly shape. Finally, open the baffle at the center part of the rolling disc, and the black tea falls through the baffle to complete the rolling process of the black tea.

[0004] However, there is a significant problem in the current black tea production process: After the rolling process is completed, due to the long-term friction between the black tea and the rolling disc, the tea leaves are prone to sticking to each other to form lumps, which causes the black tea to accumulate during the feeding process and is not conducive to subsequent processing. To solve this problem, the staff has to perform secondary processing to break up the black tea so as to smoothly carry out the subsequent process. This additional operation step not only increases the working time but also brings unnecessary trouble and affects the overall production efficiency. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device and process for preparing black tea.

[0006] To achieve the above object, the present invention provides the following technical solution: A black tea preparation and processing device, including a kneading barrel arranged at the top of a kneading plate. A pressure unit is provided at the top of the kneading barrel, and the pressure unit is used to increase the air pressure inside the kneading barrel.

A first spring is fixedly connected between the lifting platform and the lifting block. A first nylon rope is fixedly connected to the bottom end of the lifting block, and the first nylon rope penetrates through the lifting platform and extends to the outside of the lifting platform. One end of the first nylon rope far from the lifting block is fixedly connected to a first roller. A second motor is fixedly connected to the top end of the base, and the first roller is fixedly connected to the outside of the output end of the second motor.

[0010] Furthermore, the transmission mechanism includes a third spur gear, a transmission rod, a concave plate, a first helical gear and a second helical gear. The third spur gear meshes with the first spur gear. The transmission rod is fixedly connected to the inside of the third spur gear. One end of the transmission rod is rotatably connected to the concave plate. The concave plate is fixedly connected to the lifting block far from the second spur gear. The end of the dispersing roller far from the second spur gear penetrates through the concave plate and extends to the inside of the concave plate. The end of the dispersing roller far from the second spur gear is fixedly connected to the second helical gear.

[0011] Furthermore, the output end of the second motor is provided with a lifting mechanism, and the lifting mechanism is used to drive the kneading barrel to rise and fall.

[0012] Furthermore, the lifting mechanism includes a worm, the worm is fixedly connected to the output end of the second motor, the outer side of the worm is meshed with a turbine, the inside of the turbine is fixedly connected to a connecting rod, the outer side of the connecting rod is rotatably connected to a pair of limit rods, the ends of the pair of limit rods away from the connecting rod are respectively fixed to the outer sides of a pair of hollow tubes, both ends of the connecting rod are fixedly connected to a third bevel gear, both sides of the second motor are provided with a second roller, both ends of the second roller are rotatably connected to an L-plate, and the L-plate is fixed to the outer side of the hollow tube.

A fixed plate is fixedly connected to the inner wall of the hollow tube, and a second spring is fixedly connected between the support rod and the fixed plate.

[0013] A black tea preparation and processing process, the process comprising the following steps:

[0014] S1. Pour the tea leaves to be processed into the kneading barrel, apply pressure to the tea leaves through the press unit at the top of the kneading barrel, and start the first motor. When the first motor is running, it drives the protruding rod to rotate through the first spur gear. The rotation of the protruding rod drives the second hinge plate to rotate. The rotation of the second hinge plate cooperates with the position limit of a pair of first hinge plates, thereby driving the hinge bone to rotate back and forth;

[0015] S2: At this time, the tea leaves inside the kneading barrel are constantly rubbing against the top of the kneading plate, destroying the cell walls of the tea leaves, causing the tea branches to overflow, and physically making the tea leaves into a curled shape. When the tea leaves are kneaded, the turning mechanism is activated;

[0016] S3, when the turning mechanism is in operation, it first drives the baffle and the scattering roller to move downward for a distance. When the baffle is out of the kneading plate, the turning mechanism drives the baffle and the scattering roller to turn synchronously, and the scattering roller is above the baffle.

[0017] S4. During the movement of the baffle, the tea leaves on the top of the kneading plate begin to fall. After the baffle and the scattering roller flip, the tea leaves will contact the scattering roller during the falling process. The first spur gear will drive the transmission mechanism to operate when it rotates, and the operation of the transmission mechanism will drive the scattering roller to rotate continuously.

[0018] S5. With the operation of the turning mechanism, the scattering roller can turn and rotate. In this way, when the tea leaves fall and contact the scattering roller, the scattering roller will rotate and hit the tea leaves to break up the clumped tea leaves.

[0019] The technical effects and advantages of the black tea preparation and processing device and process of the present invention are as follows:

[0020] (1) Through the structural design of the flipping mechanism and the transmission mechanism, it is realized that when the flipping mechanism is in operation, it drives the baffle and the scattering roller to move downward for a distance. When the baffle is separated from the inside of the kneading plate, the flipping mechanism drives the baffle and the scattering roller to flip synchronously, and the scattering roller is placed above the baffle. When the first spur gear rotates, it drives the transmission mechanism to operate, and the operation of the transmission mechanism drives the scattering roller to rotate continuously. In conjunction with the operation of the flipping mechanism, the function of changing the position of the scattering roller and rotating it can be achieved. In this way, when the tea leaves fall and contact the scattering roller, the scattering roller will rotate and hit the tea leaves, breaking up the clumped tea leaves.

[0021] (2) Through the structural design of the second motor and the lifting mechanism, the second motor drives the lifting mechanism to operate. When the lifting mechanism operates, it drives a pair of support rods to move upward, and the upward movement of the pair of support rods will drive a pair of first hinge plates to move upward, and the upward movement of the pair of first hinge plates will drive the kneading barrel to move upward through the hinge bones. At this time, the kneading barrel will not fit with the kneading plate, and there will be a certain amount of space for the tea leaves to move between the two. The tea leaves will fall in a better shape, avoiding the friction between the kneading barrel and the kneading plate, which will cause the tea leaves to pass through the baffle and produce a "shear" effect.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figure 1 - Figure 7 As shown in the figure, a black tea preparation and processing device includes a kneading barrel 2 arranged on the top of a kneading disc 1. A pressure unit is arranged on the top of the kneading barrel 2, and the pressure unit is used to increase the air pressure inside the kneading barrel 2. A hinge bone 3 is fixedly connected to the outside of the kneading barrel 2. A baffle 4 is arranged inside the kneading disc 1. The bottom ends of the hinge bone 3 are respectively hinged with a pair of first hinge plates 5 and a second hinge plate 6. A convex rod 7 is fixedly connected to the bottom end of the second hinge plate 6. A first spur gear 8 is slidably connected to the outside of the convex rod 7. A first motor 9 is arranged at the bottom end of the first spur gear 8, and the first spur gear 8 is fixedly connected to the output end of the first motor 9. The first motor 9 is fixedly connected to the bottom end of a base 10. The bottom ends of a pair of the first hinge plates 5 are respectively hinged with a support rod 11. A hollow tube 12 is slidably connected to the outside of the support rod 11, and the hollow tube 12 is fixedly connected to the top end of the base 10. The device further includes:

[0036] The disintegrating roller 13 is arranged at the bottom end of the baffle plate 4. A turnover mechanism is arranged at the bottom end of the baffle plate 4, and the turnover mechanism is used to open the baffle plate 4 and change the positions of the baffle plate 4 and the disintegrating roller 13;

[0037] A transmission mechanism arranged outside the first spur gear 8, and the transmission mechanism is used to drive the disintegrating roller 13 to rotate.

[0038] There is a significant problem in the current black tea production process: after the rolling process is completed, due to the long-term friction between the black tea and the rolling plate 1, the tea leaves tend to stick to each other and form lumps, which leads to a piled-up state of the black tea in the feeding link, and is not conducive to subsequent processing. To solve this problem, the staff has to carry out secondary processing to break up the black tea so as to smoothly carry out the subsequent process. This additional operation step not only increases the working time, but also brings unnecessary trouble and affects the overall production efficiency. When the embodiment of the present invention is in use, the tea leaves to be processed are poured into the interior of the rolling barrel 2, and pressure is applied to the tea leaves through the pressure unit at the top end of the rolling barrel 2 (the pressure unit is a conventional technology in the existing rolling machine and the technology is mature, so it will not be elaborated too much in the article). The first motor 9 is started. When the first motor 9 operates, it drives the convex rod 7 to rotate through the first spur gear 8. When the convex rod 7 rotates, it will drive the second hinge plate 6 to rotate. The rotation of the second hinge plate 6, in cooperation with the limitation of a pair of first hinge plates 5, further drives the hinge bone 3 to rotate reciprocally. At this time, the tea leaves inside the rolling barrel 2 continuously rub against the top end of the rolling plate 1, breaking the cell walls of the tea leaves and causing the tea branches to overflow, and making the tea leaves into a curly shape in a physical way. When the rolling of the tea leaves is completed, the turnover mechanism is started. When the turnover mechanism is operating, it first drives the baffle plate 4 and the disintegrating roller 13 to move downward by a certain distance. When the baffle plate 4 disengages from the interior of the rolling plate 1, the turnover mechanism drives the baffle plate 4 and the disintegrating roller 13 to turn synchronously, placing the disintegrating roller 13 above the baffle plate 4. And during the movement of the baffle plate 4, the tea leaves at the top end of the rolling plate 1 start to fall. After the baffle plate 4 and the disintegrating roller 13 are turned over, the tea leaves will come into contact with the disintegrating roller 13 during the falling process. When the first spur gear 8 rotates, it will drive the transmission mechanism to operate, and the operation of the transmission mechanism will drive the disintegrating roller 13 to rotate continuously. In cooperation with the operation of the turnover mechanism, the function of changing the position and rotating the disintegrating roller 13 can be achieved. In this way, when the tea leaves fall and contact the disintegrating roller 13, the disintegrating roller 13 will rotate and hit the tea leaves to break up the clumped tea leaves.

[0039] Such as Figure 4 、 Figure 5 and Figure 6As shown in the figure, the flipping mechanism includes a pair of circular plates 14, and both of the pair of circular plates 14 are fixedly connected to the bottom end of the baffle 4. One end of the dispersing roller 13 is rotatably connected to the circular plate 14, and the other end of the dispersing roller 13 penetrates through the circular plate 14 and extends to the outside of the circular plate 14. A pair of lifting platforms 15 are fixedly connected to the bottom end of the kneading disc 1. A lifting block 16 is slidably connected to the outside of both of the pair of lifting platforms 15. A steering rod 17 is rotatably connected to the inside of the lifting block 16. One end of the steering rod 17 close to the dispersing roller 13 is fixedly connected to the circular plate 14. A second spur gear 18 is fixedly connected to the end of the steering rod 17 far from the circular plate 14. A rack 19 is fixedly connected to one end of the lifting platform 15. The rack 19 is located below the second spur gear 18. A first spring 20 is fixedly connected between the lifting platform 15 and the lifting block 16. A first nylon rope 21 is fixedly connected to the bottom end of the lifting block 16. The first nylon rope 21 penetrates through the lifting platform 15 and extends to the outside of the lifting platform 15. One end of the first nylon rope 21 far from the lifting block 16 is fixedly connected to a first roller 22. A second motor 23 is fixedly connected to the top end of the base 10. The first roller 22 is fixedly connected to the outside of the output end of the second motor 23.

[0040] To achieve the function of opening the baffle 4 and flipping the dispersing roller 13, in the use of the embodiment of the present invention, the second motor 23 is started. When the second motor 23 operates, it drives the first roller 22 to rotate. When the first roller 22 rotates, it will pull the first nylon rope 21, causing it to wind around the outside of the first roller 22. After one end of the first nylon rope 21 is stressed, it will pull the lifting block 16. When the lifting block 16 moves downward along the lifting table 15, it will squeeze the first spring 20, causing the first spring 20 to deform and generate elastic potential energy. During the downward movement of the lifting block 16, it will also drive the circular plate 14 to move downward through the steering rod 17. When the circular plate 14 moves downward, it will drive the baffle 4 and the dispersing roller 13 to move downward. When the baffle 4 moves downward and is separated from the inner end of the kneading plate 1 by a certain distance, the second spur gear 18 meshes with the rack 19, and the second spur gear 18 rotates along the rack 19. The rotation of the second spur gear 18 further drives the circular plate 14 to rotate through the steering rod 17, and the rotation of the circular plate 14 drives the baffle 4 to flip. When the second spur gear 18 moves downward and disengages from the meshing with the rack 19, the baffle 4 just flips 180 degrees, and the second motor 23 stops rotating and remains stationary. At this time, the dispersing roller 13 is directly above the baffle 4. Thus, the blocking of the baffle 4 on the center point of the kneading plate 1 ends, and the tea leaves at the top of the kneading plate 1 can be discharged through the center of the kneading plate 1. And during the discharging process, the tea leaves will first contact the dispersing roller 13, and the dispersing roller 13 will then impact and disperse the agglomerated tea leaves. It should be noted that the friction between the steering rod 17 and the lifting block 16 is relatively large. At the moment when the second spur gear 18 disengages from the meshing with the rack 19, the steering rod 17 will stop rotating, and when the dispersing roller 13 rotates to disperse the tea leaves, the steering rod 17 still will not rotate, improving the stability of the device during operation. When the tea leaf discharging is completed, the second motor 23 is controlled to rotate in the reverse direction. The pulling of the first nylon rope 21 by the second motor 23 through the first roller 22 ends, and the squeezing of the first spring 20 by the lifting block 16 also ends. The first spring 20 will then release the elastic potential energy, pushing the lifting block 16 to reset. The lifting block 16 drives the second spur gear 18 to move upward and meshes with the rack 19 again. At this time, the steering rod 17 rotates in the reverse direction to reset, and the steering rod 17 further drives the baffle 4 to rotate in the reverse direction to reset through the circular plate 14, and it is again clamped inside the kneading plate 1. It should be noted that the elastic potential energy of the first spring 20 is relatively large and can overcome the friction between the steering rod 17 and the lifting block 16.

[0041] Such as Figure 6 And Figure 7As shown, the transmission mechanism includes a third spur gear 24, a transmission rod, a concave plate 25, a first helical gear 26 and a second helical gear 27. The third spur gear 24 meshes with the first spur gear 8. The transmission rod is fixedly connected inside the third spur gear 24. One end of the transmission rod is rotatably connected to the concave plate 25. The concave plate 25 is fixedly connected to the lifting block 16 away from the second spur gear 18. One end of the tea leaf dispersing roller 13 away from the second spur gear 18 penetrates through the concave plate 25 and extends into the concave plate 25. One end of the tea leaf dispersing roller 13 away from the second spur gear 18 is fixedly connected to the second helical gear 27. The first helical gear 26 is fixedly connected to one end of the transmission rod away from the third spur gear 24. The first helical gear 26 meshes with the second helical gear 27.

[0042] When the tea leaves are being fed, the kneading barrel 2 is also rotating reciprocally. When the first motor 9 provides the driving source for the kneading barrel 2, the first motor 9 will also drive the third spur gear 24 to rotate synchronously through the first spur gear 8. The rotation of the third spur gear 24 will drive the transmission rod to rotate. The rotation of the transmission rod will then drive the second helical gear 27 to rotate through the first helical gear 26. The rotation of the second helical gear 27 will drive one end of the tea leaf dispersing roller 13 away from the second spur gear 18 to rotate. The rotation of the tea leaf dispersing roller 13 can disperse the agglomerated tea leaves that fall into contact with the tea leaf dispersing roller 13. When the lifting block 16 moves up and down, since it is fixedly connected to the concave plate 25, it will drive the concave plate 25 to move synchronously. In this way, the concave plate 25 can drive the third spur gear 24 to move synchronously through the transmission rod, ensuring that the third spur gear 24 is always in mesh with the first spur gear 8, and thus ensuring the continuous rotation of the tea leaf dispersing roller 13.

[0043] As Figure 1 、 Figure 8 and Figure 9 shown, a lifting mechanism is provided at the output end of the second motor 23. The lifting mechanism is used to drive the kneading barrel 2 to lift and lower.

[0044] When the tea leaves inside the kneading barrel 2 are fed through the center point of the kneading plate 1, since the kneading barrel 2 is in a continuous working state, during the process of the tea leaves passing through the center point of the kneading plate 1, they will inevitably be affected by the frictional force generated by the rotational movement of the kneading barrel 2. This frictional effect is likely to cause a "shearing" effect on the tea leaves, resulting in the breakage of the tea leaves, which not only damages the original appearance of the tea leaves but may also have an adverse impact on their quality. When the embodiment of the present invention is in use, when the second motor 23 is started, it indicates that the baffle 4 disengages from the inside of the kneading plate 1 and the tea leaves are in the feeding state. At this time, the second motor 23 will drive the lifting mechanism to operate. When the lifting mechanism operates, it will drive a pair of support rods 11 to move upward, and the upward movement of a pair of support rods 11 will drive a pair of first hinge plates 5 to move upward, and the upward movement of a pair of first hinge plates 5 will drive the kneading barrel 2 to move upward through the hinge bone 3. It should be noted that the convex rod 7 is slidably connected to the first positive gear 8. When the hinge bone 3 rises, the convex rod 7 moves upward along the inside of the first positive gear 8 without affecting the normal rotation of the first positive gear 8 to drive the convex rod 7. At this time, the kneading barrel 2 will not be in contact with the kneading plate 1, and there will be a certain amount of movement space for the tea leaves between the two, and the tea leaves will fall in a better shape, avoiding the friction between the kneading barrel 2 and the kneading plate 1 and causing the "shearing" effect of the tea leaves passing through the baffle 4.

[0045] As Figure 1 、 Figure 8 and Figure 9 shown, the lifting mechanism includes a worm 28, the worm 28 is fixedly connected to the output end of the second motor 23, a worm gear 29 is meshed outside the worm 28, a connecting rod 30 is fixedly connected inside the worm gear 29, a pair of limiting rods 31 are rotatably connected outside the connecting rod 30, and one ends of the pair of limiting rods 31 far from the connecting rod 30 are respectively fixedly connected to the outside of a pair of hollow tubes 12. Both ends of the connecting rod 30 are fixedly connected with third helical gears 32. Second rollers 33 are arranged on both sides of the second motor 23. Both ends of the second rollers 33 are rotatably connected with L plates 34, and the L plates 34 are fixedly connected to the outside of the hollow tubes 12. A fourth helical gear 35 is fixedly connected to the outside of the second roller 33 near one end of the third helical gear 32, and the fourth helical gear 35 is meshed with the third helical gear 32. A second nylon rope 36 is fixedly connected to the bottom end of the support rod 11. One end of the second nylon rope 36 far from the support rod 11 penetrates through the outside of the hollow tube 12, and one end of the second nylon rope 36 far from the support rod 11 is wound around the outside of the second roller 33. A guide wheel 37 is rotatably connected to the inner wall of the hollow tube 12, and the second nylon rope 36 is in contact with the inside of the guide wheel 37. A fixing plate 38 is fixedly connected to the inner wall of the hollow tube 12, and a second spring 39 is fixedly connected between the support rod 11 and the fixing plate 38.

[0046] In the initial state, one end of the second nylon rope 36 is wound around the outside of the second roller 33. The second nylon rope 36 pulls the support rod 11 to squeeze the second spring 39, and the second spring 39 is in a deformed and compressed state. When the second motor 23 operates, the second motor 23 drives the worm 28 to rotate. The worm 28 will drive the turbine 29 to rotate, and the rotation of the turbine 29 will drive the connecting rod 30 to rotate. The connecting rod 30 will drive the fourth bevel gear 35 to rotate through the third bevel gear 32. The rotation of the fourth bevel gear 35 will drive the second roller 33 to rotate. The rotation of the second roller 33 will gradually release one end of the second nylon rope 36. At this time, the pulling force of the second nylon rope 36 on the support rod 11 gradually ends, the extrusion force on the second spring 39 gradually decreases, and the second spring 39 will gradually release its elastic potential energy, pushing the support rod 11 upward. The upward movement of the support rod 11 will drive the hinge bone 3 and the kneading barrel 2 to rise through the first hinge plate 5. It should be noted that the elastic potential energy of the second spring 39 is sufficient to support and push a pair of first hinge plates 5, second hinge plates 6, hinge bone 3 and kneading barrel 2 to move upward. When the second motor 23 rotates in the reverse direction, the second nylon rope 36 will be wound around the outside of the second roller 33 again. The end of the second nylon rope 36 away from the second roller 33 will pull the support rod 11 again, causing the support rod 11 to squeeze the second spring 39. The second spring 39 deforms under the force and generates elastic potential energy. The support rod 11 will drive the hinge bone 3 and the kneading barrel 2 to move downward and reset to the initial position through a pair of first hinge plates 5.

[0047] A black tea preparation and processing process, which includes the following steps:

[0048] S1. Pour the tea leaves to be processed into the interior of the kneading barrel 2. Apply pressure to the tea leaves through the pressure unit at the top of the kneading barrel 2. Start the first motor 9. When the first motor 9 operates, it drives the convex rod 7 to rotate through the first spur gear 8. The rotation of the convex rod 7 will drive the second hinge plate 6 to rotate. The rotation of the second hinge plate 6, in cooperation with the limitation of a pair of first hinge plates 5, will drive the hinge bone 3 to rotate reciprocally.

[0049] S2. At this time, the tea leaves inside the kneading barrel 2 continuously rub against the top of the kneading plate 1, breaking the cell walls of the tea leaves and causing the tea branches to overflow. The tea leaves are made into a curly shape by physical means. When the tea leaves are kneaded, start the flipping mechanism.

[0050] S3. When the flipping mechanism operates, it first drives the baffle 4 and the dispersing roller 13 to move downward by a certain distance. When the baffle 4 disengages from the interior of the kneading plate 1, the flipping mechanism drives the baffle 4 and the dispersing roller 13 to flip synchronously, placing the dispersing roller 13 above the baffle 4.

[0051] S4. And during the movement of the baffle 4, the tea leaves at the top of the kneading plate 1 start to fall. After the baffle 4 and the dispersing roller 13 are flipped, the tea leaves will come into contact with the dispersing roller 13 during the falling process. When the first spur gear 8 rotates, it will drive the transmission mechanism to operate, and the operation of the transmission mechanism will drive the dispersing roller 13 to rotate continuously;

[0052] S5. Cooperating with the operation of the flipping mechanism, the function of flipping and rotating the dispersing roller 13 can be achieved. In this way, when the tea leaves fall and come into contact with the dispersing roller 13, the dispersing roller 13 will rotate and impact the tea leaves to break up the agglomerated tea leaves.

[0053] Working principle: There is a significant problem in the current black tea production process. After the rolling process is completed, due to the long-term friction between the black tea and the rolling plate 1, the tea leaves tend to stick to each other and form lumps, which causes the black tea to accumulate during the feeding process and is not conducive to subsequent processing. To solve this problem, workers have to perform secondary processing to break up the black tea so as to smoothly carry out the subsequent processes. This additional operation step not only increases the working time but also brings unnecessary trouble and affects the overall production efficiency. When the embodiment of the present invention is in use, the tea leaves to be processed are poured into the interior of the rolling barrel 2, and pressure is applied to the tea leaves through the pressure unit at the top of the rolling barrel 2 (the pressure unit is a conventional technology in the existing rolling machine and is technically mature, so it will not be elaborated in detail in this article). The first motor 9 is started. When the first motor 9 operates, it drives the convex rod 7 to rotate through the first spur gear 8. When the convex rod 7 rotates, it will drive the second hinge plate 6 to rotate. The rotation of the second hinge plate 6, in cooperation with the limitation of a pair of first hinge plates 5, will drive the hinge bone 3 to rotate reciprocally. At this time, the tea leaves inside the rolling barrel 2 continuously rub against the top of the rolling plate 1, breaking the cell walls of the tea leaves and causing the tea branches to overflow, and making the tea leaves into a curly shape by physical means. When the rolling of the tea leaves is completed, the flipping mechanism is started. When the flipping mechanism operates, it first drives the baffle 4 and the dispersing roller 13 to move downward a certain distance. When the baffle 4 disengages from the inside of the rolling plate 1, the flipping mechanism drives the baffle 4 and the dispersing roller 13 to flip synchronously, placing the dispersing roller 13 above the baffle 4. And during the movement of the baffle 4, the tea leaves on the top of the rolling plate 1 start to fall. After the baffle 4 and the dispersing roller 13 flip, the tea leaves will contact the dispersing roller 13 during the falling process. When the first spur gear 8 rotates, it will drive the transmission mechanism to operate. The operation of the transmission mechanism will drive the dispersing roller 13 to rotate continuously. In cooperation with the operation of the flipping mechanism, the function of changing the position and rotating the dispersing roller 13 can be achieved. In this way, when the tea leaves fall and contact the dispersing roller 13, the dispersing roller 13 will rotate and impact the tea leaves to break up the clumped tea leaves. To realize the function of opening the baffle 4 and flipping the dispersing roller 13, when the embodiment of the present invention is in use, the second motor 23 is started. When the second motor 23 operates, it drives the first roller 22 to rotate. When the first roller 22 rotates, it will pull the first nylon rope 21, causing it to wind around the outside of the first roller 22. After one end of the first nylon rope 21 is stressed, it will pull the lifting block 16. When the lifting block 16 moves downward along the lifting platform 15, it will squeeze the first spring 20, causing the first spring 20 to deform and generate elastic potential energy. During the downward movement of the lifting block 16, it will also drive the round plate 14 to move downward through the steering rod 17. When the round plate 14 moves downward, it will drive the baffle 4 and the dispersing roller 13 to move downward. When the baffle 4 moves downward and disengages from the inside of the rolling plate 1 by a certain distance, the second spur gear 18 meshes with the rack 19, and the second spur gear 18 rotates along the rack 19. The rotation of the second spur gear 18 will drive the round plate 14 to rotate through the steering rod 17. When the round plate 14 rotates, it will drive the baffle 4 to flip.When the second spur gear 18 moves downward and disengages from the rack 19, the baffle 4 just flips 180 degrees, and the second motor 23 then stops rotating and remains stationary. At this time, the dispersing roller 13 is directly above the baffle 4. Thus, the blocking of the center point of the kneading plate 1 by the baffle 4 ends, and the tea leaves at the top of the kneading plate 1 can be discharged through the center of the kneading plate 1. Moreover, during the discharging process, the tea leaves will first contact the dispersing roller 13, and the dispersing roller 13 will then impact and disperse the agglomerated tea leaves. It should be noted that the friction between the steering rod 17 and the lifting block 16 is relatively large. At the moment when the second spur gear 18 disengages from the rack 19, the steering rod 17 will stop rotating, and when the dispersing roller 13 rotates to disperse the tea leaves, the steering rod 17 still will not rotate, improving the stability of the device during operation. When the tea leaf discharging is completed, control the second motor 23 to rotate in the reverse direction. The pulling of the first nylon rope 21 by the second motor 23 through the first roller 22 ends. The extrusion of the lifting block 16 by the first spring 20 also ends. The first spring 20 will then release its elastic potential energy, pushing the lifting block 16 to reset. The lifting block 16 drives the second spur gear 18 to move upward and engage with the rack 19 again. The steering rod 17 rotates in the reverse direction to reset at this time. The steering rod 17 then drives the baffle 4 to rotate in the reverse direction to reset through the circular plate 14 and is again clamped inside the kneading plate 1. It should be noted that the elastic potential energy of the first spring 20 is relatively large, which can overcome the friction between the steering rod 17 and the lifting block 16. When the tea leaves are being discharged, the kneading barrel 2 is also continuously rotating back and forth. When the first motor 9 provides the driving source for the kneading barrel 2, the first motor 9 will also drive the third spur gear 24 to rotate synchronously through the first spur gear 8. The rotation of the third spur gear 24 will drive the transmission rod to rotate. The rotation of the transmission rod will drive the second bevel gear 27 to rotate through the first bevel gear 26. The rotation of the second bevel gear 27 will drive the end of the dispersing roller 13 away from the second spur gear 18 to rotate. The rotation of the dispersing roller 13 can then disperse the agglomerated tea leaves that fall and contact the dispersing roller 13. When the lifting block 16 moves up and down, since it is fixedly connected to the concave plate 25, it will drive the concave plate 25 to move synchronously. In this way, the concave plate 25 can drive the third spur gear 24 to move synchronously through the transmission rod, ensuring that the third spur gear 24 is always engaged with the first spur gear 8, and thus ensuring the continuous rotation of the dispersing roller 13. When the tea leaves inside the kneading barrel 2 are discharged through the center point of the kneading plate 1, since the kneading barrel 2 device is in a continuous working state, during the process of the tea leaves passing through the center point of the kneading plate 1, it will inevitably be affected by the frictional force generated by the rotational movement of the kneading barrel 2. This frictional effect is likely to cause a "shearing" effect on the tea leaves, resulting in the breakage of the tea leaves, which not only damages the original appearance of the tea leaves but may also have an adverse impact on their quality. When the embodiment of the present invention is in use, when the second motor 23 is started, it indicates that the baffle 4 disengages from the inside of the kneading plate 1 and the tea leaves are in the discharging state. At this time, the second motor 23 will drive the lifting mechanism to operate. When the lifting mechanism operates, it will drive a pair of support rods 11 to move upward.When a pair of support rods 11 move upward, they will drive a pair of first hinge plates 5 to move upward. When the pair of first hinge plates 5 move upward, they will drive the kneading barrel 2 to move upward through the hinge bone 3. It should be noted that the convex rod 7 is slidably connected to the first spur gear 8. When the hinge bone 3 rises, the convex rod 7 moves upward along the inside of the first spur gear 8 without affecting the normal rotation of the first spur gear 8 driving the convex rod 7. At this time, the kneading barrel 2 will not be in contact with the kneading plate 1, and there will be a certain amount of moving space for the tea leaves between the two. The tea leaves will fall in a better shape, avoiding the friction between the kneading barrel 2 and the kneading plate 1, which causes the "shearing" effect of the tea leaves passing through the baffle 4. In the initial state, one end of the second nylon rope 36 is wound around the outside of the second roller 33. The second nylon rope 36 pulls the support rod 11 to squeeze the second spring 39, and the second spring 39 is in a deformed and compressed state. When the second motor 23 operates, the second motor 23 drives the worm 28 to rotate. The worm 28 will drive the turbine 29 to rotate. The rotation of the turbine 29 will drive the connecting rod 30 to rotate. The connecting rod 30 will drive the fourth helical gear 35 to rotate through the third helical gear 32. The rotation of the fourth helical gear 35 will drive the second roller 33 to rotate. When the second roller 33 rotates, it will gradually release one end of the second nylon rope 36. At this time, the pulling force of the second nylon rope 36 on the support rod 11 gradually ends, and the extrusion force on the second spring 39 gradually decreases. The second spring 39 will gradually release its elastic potential energy and push the support rod 11 upward. The upward movement of the support rod 11 will drive the hinge bone 3 and the kneading barrel 2 to rise through the first hinge plate 5. It should be noted that the elastic potential energy of the second spring 39 is sufficient to support and push a pair of first hinge plates 5, second hinge plates 6, hinge bone 3 and kneading barrel 2 to move upward. When the second motor 23 rotates in the reverse direction, the second nylon rope 36 will be wound around the outside of the second roller 33 again. The end of the second nylon rope 36 away from the second roller 33 will pull the support rod 11 again, causing the support rod 11 to squeeze the second spring 39. The second spring 39 deforms under force and generates elastic potential energy. The support rod 11 will drive the hinge bone 3 and the kneading barrel 2 to move downward and reset to the initial position through a pair of first hinge plates 5.,
