Description

Technical Field

[0001] This invention relates to the field of tea leaf straightening machine technology, and more specifically, to a tea leaf straightening machine for a compound linkage mechanism and its method of use. Background Technology

[0002] Tea leaf shaping is one of the core processes in tea processing. Through shaping, straightening, and drying, the tea leaves are formed into tightly rolled, regular shapes, while removing excess moisture from the surface of the tea leaves and locking in their aroma and nutrients.

[0003] The core working principle of existing tea shaping machines is relatively simple. It mainly involves placing the tea leaves to be processed in the U-shaped groove of the shaping pot, heating the shaping pot with an electric heating plate to soften the tea leaves and make them easier to shape, while driving the shaping pot to make reciprocating linear motion. The tea leaves move synchronously with the pot in the U-shaped groove, and rely on their own inertia to collide and rub against the inner wall of the U-shaped groove, gradually straightening and shaping the tea leaves, and completing the initial shaping process.

[0004] However, this traditional method of shaping tea leaves relies solely on the inertia of the heated leaves and the impact with the inner wall of the U-shaped groove. The impact force is dispersed and the direction is unidirectional, which cannot form a precise squeezing and kneading effect on the tea leaves. This results in extremely low tea leaf shaping efficiency, requiring a long period of reciprocating motion to form regular strips of tea leaves, which greatly increases processing time and reduces production efficiency. Summary of the Invention

[0005] This invention provides a tea-stripping machine with a composite linkage mechanism and its usage method. The composite linkage drive mechanism drives the tea-stripping trough to move back and forth. The arc plate at the top of the U-shaped trough moves with the trough to achieve automatic opening and closing, forming a bidirectional extrusion on the tea leaves, similar to the action of hand kneading. At the same time, the turning mechanism realizes the automatic discharge of the tea leaves after the tea-stripping is completed, thereby solving the problem of low shaping efficiency of traditional tea-stripping machines mentioned in the background art.

[0006] To achieve the above objectives, the tea-stripping machine for the compound linkage mechanism includes a frame, a frame mounted on the top of the frame, a stripping trough movably mounted on the top of the frame, and a discharge trough mounted on the top of the frame. The discharge trough has an inclined structure to facilitate the rapid sliding of tea leaves and prevent accumulation. The discharge trough is located at the discharge end of the stripping trough, and its width is greater than the width of the stripping trough to ensure that all the stripped tea leaves can fall into the discharge trough.

[0007] A drive mechanism is installed between the frame and the control frame. The drive mechanism provides power for the reciprocating movement of the trough pan. It adopts a composite linkage transmission structure, which ensures smooth transmission and high precision.

[0008] A turning mechanism is installed between the frame and the shaping trough. The turning mechanism is used to drive the shaping trough to turn over after the shaping is completed, so as to realize the automatic discharge of tea leaves, replace the traditional manual pouring, avoid secondary damage to the tea leaves, and improve processing efficiency and product quality.

[0009] The frame has symmetrical mounting holes on its two side plates. Wear-resistant copper sleeves are embedded in the mounting holes to reduce friction loss during shaft rotation and improve rotational flexibility. Shafts are symmetrically mounted on both sides of the shaping pot and are welded to it. The front end of the shaping pot is rotatably mounted in the mounting hole via the shaft, allowing it to freely rotate around the shaft and providing a structural basis for subsequent automatic material discharge. The bottom of the shaping pot is supported within the frame, which provides stable support and ensures that the shaping pot does not shift or shake when it moves synchronously with the frame, thus guaranteeing the stability of tea shaping.

[0010] An electric heating plate is installed inside the frame. The electric heating plate is a far-infrared heating plate, which provides uniform heating, rapid temperature rise, and precise temperature control to meet the temperature requirements of different tea leaves during processing.

[0011] In the above technical solution, the top of the tea-strip shaping pot is provided with multiple parallel U-shaped grooves. The cross-section of the U-shaped grooves is arc-shaped, and the curvature is optimized by ergonomics and the tea-shaping requirements to conform to the natural shape of the tea strips, so as to avoid the tea being squeezed and broken during the shaping process. The multiple U-shaped grooves are evenly distributed, which can realize the simultaneous shaping of multiple groups of tea, thereby improving processing efficiency.

[0012] Both sides of the upper port of the U-shaped groove are rotatably mounted with arc-shaped plates via pins. The arc-shaped plates are made of food-grade elastic alloy material, which has good elasticity and toughness. They can undergo slight deformation when subjected to force to avoid squeezing the tea leaves and causing them to break. At the same time, they can quickly reset. When the tea-sorting pot moves, the arc-shaped plates can automatically open and close according to inertia without the need for additional driving components, simplifying the structure and reducing energy consumption.

[0013] Based on the above, the structure of the drive mechanism is disclosed next. The drive mechanism adopts a compound linkage transmission structure, including a servo motor one fixedly installed on the top of the frame. The servo motor one is a high-precision servo motor with adjustable speed and smooth transmission. It can accurately control the reciprocating movement speed of the tea-stripping pan to adapt to the tea-stripping requirements of different teas. The output end of the servo motor one is fixedly installed with a synchronous pulley one through a coupling. The top of the frame is rotatably installed with a synchronous pulley two through a bearing. A synchronous belt is sleeved between the synchronous pulley one and the synchronous pulley two. The synchronous belt is a high-strength rubber synchronous belt with a toothed structure on its surface. It precisely meshes with the synchronous pulley one and the synchronous pulley two, resulting in high transmission efficiency and no slippage, ensuring stable power transmission.

[0014] A rotating wheel is fixedly installed at the front end of the second synchronous wheel. The rotating wheel rotates coaxially with the second synchronous wheel. An installation shaft is fixedly connected to the outer wall of the rotating wheel. The installation shaft is offset from the center of the rotating wheel, forming an eccentric shaft structure. A push rod is rotatably installed between the installation shaft and the side plate of the frame. The push rod is made of high-strength alloy rod, which has good bending and tensile resistance and can withstand repeated pushing and pulling forces without deformation.

[0015] Based on the above, the material turning mechanism also adopts a composite linkage structure, including a servo motor two fixedly installed on the top of the frame. The output end of the servo motor two is fixedly installed with a connecting rod one via a coupling. The end of the connecting rod one is rotatably installed with a connecting rod two. Both connecting rod one and connecting rod two are made of high-strength alloy rods, which are firmly connected, rotate flexibly, and can withstand the weight of the tea-making pot and tea leaves without bending or deformation. A guide rod is fixedly installed on the rear side of the tea-making pot. The guide rod is a cylindrical rod with a polished surface. A sleeve is fixedly connected to the end of the connecting rod two. The sleeve is made of wear-resistant nylon material with a smooth inner wall. The sleeve is movably fitted on the outer wall of the guide rod and slides freely along the guide rod.

[0016] The method of using the tea-stripping machine for the compound linkage mechanism includes the following steps:

[0017] S1. Evenly place the tea leaves to be processed into each of the U-shaped slots of the shaping trough, turn on the electric heating plate, heat the shaping trough to the preset temperature, heat and soften the tea leaves, and prepare them for subsequent shaping.

[0018] S2. Start the drive mechanism, whose compound linkage transmission drives the frame to move back and forth on the machine frame, and simultaneously drives the strip-forming pot to move synchronously.

[0019] S3, Shaping Process

[0020] S3.1 When the tea-stripping pot moves to one side, the corresponding side arc plate automatically unfolds under the inertia of the tea leaves, and the other side arc plate closes, so that the tea leaves enter the angle formed by the arc plate and the U-shaped groove and are limited and squeezed.

[0021] S3.2 When the tea-strip pan moves in the opposite direction, the unfolded arc-shaped plate closes and laterally squeezes the tea leaves, while the other arc-shaped plate unfolds simultaneously, realizing the tea leaves' displacement and squeezing.

[0022] S3.3 The tea-forming pot continues to reciprocate, and the arc-shaped plate cycles through opening and closing states, forming a continuous bidirectional extrusion on the tea leaves, similar to hand kneading, to quickly shape the tea leaves.

[0023] S4. After the tea leaves are shaped, keep the drive mechanism running to move the shaping trough slightly back and forth. Start the tipping mechanism, whose compound linkage drive pushes the shaping trough to tilt around the axis. Utilize the weight of the tea leaves and the inertia of the trough to make the finished tea leaves slide smoothly into the discharge chute to complete the discharge.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] By using two arc-shaped plates at the top of the U-shaped trough, the inertia of the trough pot causes the arc-shaped plates to open and close automatically. When the trough pot moves to one side, the arc-shaped plate on the same side opens and the arc-shaped plate on the other side closes, allowing the tea leaves to enter the angle formed by the arc-shaped plate and the U-shaped trough. The tea leaves are compressed by the obstruction at the top of the arc-shaped plate and the inertial impact of the tea leaves themselves. When the trough pot moves in the opposite direction, the arc-shaped plates on both sides switch between open and closed states, squeezing the tea leaves laterally and vertically, achieving a kneading effect similar to hand rolling, accelerating the shaping of the tea leaves, improving the shaping efficiency, and promoting slight overflow of tea juice and cell breakage, thus optimizing the concentration of the tea soup. This solves the problems of low shaping efficiency, loose tea leaves, and poor taste of traditional tea leaf shaping machines. Attached Figure Description

[0038] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0039] Because existing tea shaping machines rely solely on the reciprocating movement of the shaping trough, and the tea leaves are shaped by impact with the inner wall of the U-shaped trough due to their own inertia, they suffer from low shaping efficiency, long processing time, and poor tea quality.

[0040] Therefore, in view of the above-mentioned problems, the present invention discloses a tea leaf straightening machine for a compound linkage mechanism and its method of use, which is described below in conjunction with the appendix. Figure 1-10 The specific embodiments of the present invention are described in detail to ensure that the technical solution of the present invention is fully disclosed, so that those skilled in the art can clearly understand and implement the present invention.

[0041] refer to Figure 1 As shown, the tea-stripping machine for a composite linkage mechanism provided by the present invention includes a frame 1. The frame 1 is made of high-strength square tubing and has an overall frame structure. Anti-slip pads are provided at the bottom to ensure stable operation without shaking. A frame 2 is installed on the top of the frame 1. The frame 2 is the mounting carrier for the tea-stripping trough 3. The tea-stripping trough 3 is movably installed on the top of the frame 2. The tea-stripping trough 3 is the core working component for tea-stripping and is made of food-grade stainless steel.

[0042] The top of the frame 1 is equipped with a discharge trough 4. The discharge trough 4 adopts an inclined structure, which facilitates the rapid sliding of tea leaves and avoids accumulation. The discharge trough 4 is located at the discharge end of the shaping pot 3, and its width is greater than the width of the shaping pot 3, ensuring that all the tea leaves after shaping can fall into the discharge trough 4 without any leakage.

[0043] A drive mechanism 5 is installed between the frame 1 and the frame 2. The drive mechanism 5 provides power for the reciprocating movement of the trough pot 3. It adopts a compound linkage transmission structure, which ensures smooth transmission and high precision.

[0044] A turning mechanism 6 is installed between the frame 1 and the shaping trough 3. The turning mechanism 6 is used to drive the shaping trough 3 to turn over after the shaping is completed, so as to realize the automatic discharge of tea leaves, replace the traditional manual pouring, avoid secondary damage to tea leaves, and improve processing efficiency and product quality.

[0045] Please refer to the details. Figure 2 As shown, the bottom of the frame 2 is equipped with multiple evenly distributed rollers 22, and the top of the frame 1 is provided with multiple sliding grooves 11 corresponding to the rollers 22. The sliding grooves 11 are elongated structures, and the rollers 22 are embedded in the sliding grooves 11 and slide in cooperation with the sliding grooves 11. The frame 2 can move back and forth in the sliding grooves 11 by means of the rollers 22. The length of the sliding grooves 11 determines the reciprocating stroke of the tea-sorting pot 3, which can be flexibly designed according to the tea-sorting requirements. Through the cooperation between the rollers 22 and the sliding grooves 11, the sliding friction of the frame 2 is converted into rolling friction, which greatly reduces the frictional resistance, makes the reciprocating movement of the frame 2 more stable and smooth, avoids jamming, and at the same time reduces the wear of parts and extends the service life of the equipment.

[0046] The two side plates of the frame 2 are symmetrically provided with mounting holes 21. Wear-resistant copper sleeves are embedded in the mounting holes 21 to reduce frictional loss when the rotating shaft 32 rotates and improve the rotation flexibility. The two sides of the shaping pot 3 are symmetrically installed with rotating shafts 32. The rotating shafts 32 are welded and fixed to the shaping pot 3. The front end of the shaping pot 3 is rotatably installed in the mounting hole 21 through the rotating shaft 32, so that the shaping pot 3 can be freely rotated around the rotating shaft 32, providing a structural basis for subsequent automatic material discharge. The bottom of the shaping pot 3 is supported in the frame 2. The frame 2 plays a stable supporting role for the shaping pot 3, ensuring that the shaping pot 3 will not deviate or shake when it moves back and forth synchronously with the frame 2, thus ensuring the stability of tea shaping.

[0047] When the drive mechanism 5 is turned on, the drive mechanism 5 drives the frame 2 to move back and forth along the slide 11. At the same time, the frame 2 drives the shaping pot 3 to move synchronously through the rotating shaft 32, so that the tea leaves in the U-shaped groove 33 move with the pot and begin the shaping operation.

[0048] The frame 2 is equipped with an electric heating plate 7, which is a far-infrared heating plate. It heats evenly and heats up quickly. It can accurately control the heating temperature and adapt to the temperature requirements of different tea leaves. The tea-forming trough 3 is located on top of the electric heating plate 7. The electric heating plate 7 heats the tea-forming trough 3 through heat conduction, so that the temperature of the tea-forming trough 3 is evenly distributed. This heats and softens the tea leaves in the U-shaped groove 33, making it easier to shape them later. At the same time, it removes excess moisture from the surface of the tea leaves and locks in the aroma and nutrients of the tea.

[0049] Next, refer to Figure 3 As shown, the top of the tea-strip shaping pot 3 has multiple parallel U-shaped grooves 33. The cross-section of the U-shaped grooves 33 is arc-shaped, and the curvature is optimized by ergonomics and the tea-shaping requirements to fit the natural shape of the tea leaves, so as to avoid the tea leaves being squeezed and broken during the shaping process. The multiple U-shaped grooves 33 are evenly distributed, which can realize the simultaneous shaping of multiple groups of tea leaves, thus improving processing efficiency.

[0050] As the tea leaves in the U-shaped groove 3 move left and right, they move synchronously with the pot due to inertia. When the pot stops moving, the tea leaves collide and rub against the inner wall of the U-shaped groove 33 due to their own inertia, gradually straightening and initially shaping the tea leaves.

[0051] However, as described in the background technology, the shaping of tea leaves relies solely on the impact between the tea leaves' own inertia and the U-shaped groove 33 after heating. The impact force is dispersed and the direction is singular, which cannot form a precise squeezing and kneading effect on the tea leaves. It requires a long processing time to produce regular strips, which is not only inefficient but also affects the quality of the tea leaves.

[0052] To address this situation and overcome the technical shortcomings of traditional straightening machines, reference was made to... Figure 4 As shown, arc-shaped plates 34 are rotatably mounted on the upper ends of both sides of the U-shaped groove 33 via pins. The arc-shaped plates 34 are made of food-grade elastic alloy material, which has good elasticity and toughness. They can undergo slight deformation when subjected to force to avoid squeezing the tea leaves and causing them to break. At the same time, they can quickly reset. When the tea leaf sorting pot 3 moves, the arc-shaped plates 34 can automatically open and close according to inertia without the need for additional driving components, simplifying the structure and reducing energy consumption.

[0053] Next, the structure of drive mechanism 5 will be disclosed, for reference. Figure 5 As shown, the drive mechanism 5 adopts a composite linkage transmission structure, including a servo motor 51 fixedly installed on the top of the frame 1. The servo motor 51 is a high-precision servo motor with adjustable speed and smooth transmission. It can accurately control the reciprocating speed of the tea-sorting pan 3 to adapt to the tea-sorting requirements of different teas. The output end of the servo motor 51 is fixedly installed with a synchronous pulley 52 through a coupling. A synchronous pulley 53 is rotatably installed on the top of the frame 1 through a bearing. A synchronous belt 54 is sleeved between the synchronous pulley 52 and the synchronous pulley 53. The synchronous belt 54 is a high-strength rubber synchronous belt with a toothed structure on its surface. It precisely meshes with the synchronous pulleys 52 and 53, resulting in high transmission efficiency and no slippage, ensuring stable power transmission.

[0054] A rotating wheel 55 is fixedly installed at the front end of the second synchronous pulley 53. The rotating wheel 55 rotates coaxially with the second synchronous pulley 53. A mounting shaft is fixedly connected to the outer wall of the rotating wheel 55. The mounting shaft is offset from the center of the rotating wheel 55 (i.e., eccentric setting), forming an eccentric shaft structure. A push rod 56 is rotatably installed between the mounting shaft and the side plate of the frame 2. The push rod 56 is made of high-strength alloy rod, which has good bending and tensile resistance and can withstand repeated pushing and pulling forces without deformation.

[0055] When servo motor 51 is turned on, servo motor 51 drives synchronous pulley 52 to rotate at a constant speed. Synchronous pulley 52 drives synchronous pulley 53 to rotate synchronously through synchronous belt 54. Synchronous pulley 53 drives rotating wheel 55 to rotate synchronously. Since the mounting shaft is eccentrically set on rotating wheel 55, the mounting shaft will make a circular motion when rotating wheel 55 rotates, which in turn drives push rod 56 to make reciprocating extension and retraction motion. One end of push rod 56 is rotatably connected to the mounting shaft, and the other end is rotatably connected to frame 2. Therefore, when push rod 56 extends and retracts, it will push frame 2 to move back and forth along slide groove 11, which in turn drives the tea-stripping trough pot 3 to move back and forth synchronously, providing power for tea-stripping.

[0056] The advantages of this composite linkage transmission structure are that the transmission is smooth and shock-free, the moving speed and stroke of the shaping trough 3 can be precisely controlled, the noise is lower, the wear is less, and the maintenance cost is lower. At the same time, the reciprocating frequency of the shaping trough 3 can be flexibly adjusted by adjusting the speed of the servo motor 51 to adapt to the shaping needs of different types of tea.

[0057] For detailed processing steps, please refer to... Figure 6-8 As shown, the following section, combining the opening and closing action of the curved plate 34 with the tea-shaping process, elaborates on the logical workflow of this invention, highlighting the core advantages of this solution:

[0058] refer to Figure 6As shown, step one: The tea leaves to be processed are evenly placed into the multiple U-shaped grooves 33 of the shaping pot 3, ensuring that the amount of tea leaves in each U-shaped groove 33 is uniform. The heating plate 7 is turned on to heat the shaping pot 3 to the preset temperature to soften the tea leaves. Then, the servo motor 51 is turned on, and the servo motor 51 drives the rotating wheel 55 to rotate at a constant speed, causing the push rod 56 to extend and push the frame 2 to move the shaping pot 3 to the left. At this time, with the inertia of the shaping pot 3 moving to the left, the arc plate 34 on the left side of the U-shaped groove 33 is inertial and unfolds outward, while the arc plate 34 on the right side remains closed. When the push rod 56 moves to the final end, the shaping pot 3 suddenly stops moving under the limiting action of the push rod 56. At this time, the tea leaves in the U-shaped groove 33 continue to move to the left due to their own inertia and enter the angle formed by the unfolded arc plate 34 on the left and the inner wall of the U-shaped groove 33. The tea leaves continuously impact the angled area due to inertia, while the curved plate 34 acts as a barrier at the top, achieving precise compression of the tea leaves at the angle, quickly straightening and tightening the tea strands. Compared to the traditional method of simply using inertia to make the tea leaves impact the inner wall, this method further improves shaping efficiency, while the compression makes the tea strands more compact, reducing breakage and leaf fragmentation.

[0059] Next reference Figure 7 As shown, in step two: As the rotating wheel 55 continues to rotate, after the push rod 56 extends to its final end, it begins to slowly retract, causing the frame 2 and the tea-forming pot 3 to move to the right. At this time, the inertia of the tea-forming pot 3 moving to the right causes the left arc plate 34 to close quickly, performing a second compression on the tea leaves located in the left angle in the first step from the side, further tightening the tea leaves. At the same time, the right arc plate 34 is pushed outward by inertia. When the push rod 56 retracts to its final end, the tea-forming pot 3 suddenly stops moving again, and the tea leaves continue to move to the right by their own inertia, entering... In the angle formed by the arc-shaped plate 34 unfolding on the right and the inner wall of the U-shaped groove 33, the arc-shaped plate 34 blocks the tea leaves at the top, while the tea leaves moving at the bottom continuously impact the tea leaves in front, creating a two-way compression on the tea leaves in the angle. This achieves a kneading effect similar to hand kneading. This two-way compression and kneading not only accelerates the shaping of the tea leaves but also promotes the slight breakage of the tea leaves' cells, causing the tea juice to slightly overflow and adhere to the surface of the tea leaves. During subsequent brewing, it can quickly release the aroma and nutrients of the tea, optimize the concentration and taste of the tea soup, and be closer to the handmade tea-making process, greatly improving the quality of the tea.

[0060] Final Reference Figure 8As shown, in step three: the push rod 56 extends again, and the shaping trough pot 3 moves to the left. The principle of this process is exactly the same as in step two. The left arc plate 34 unfolds and the right arc plate 34 closes, squeezing and kneading the tea leaves again. This cycle repeats, and the shaping trough pot 3 continues to move back and forth, while the arc plate 34 switches between open and closed states simultaneously, subjecting the tea leaves to multiple bidirectional squeezing, kneading, and impacts. This allows the tea leaves to quickly form tightly rolled and regularly shaped strips. Compared with traditional processes, the shaping efficiency of this invention is greatly improved, the processing time is shortened, and the tea strips are more regular, the broken leaf rate is reduced, the tea juice overflows evenly, and the taste is more mellow.

[0061] After the tea processing is completed, the tea-making trough 3 needs to be flipped by the turning mechanism 6 so that the tea leaves in the tea-making trough 3 fall into the discharge trough 4, realizing automatic discharge, replacing the traditional manual pouring, improving processing efficiency, and avoiding secondary damage to the tea leaves.

[0062] Next, the structure of the material turning mechanism 6 will be disclosed. Please refer to [link / reference]. Figure 9 As shown, the material turning mechanism 6 also adopts a composite linkage structure, including a servo motor 61 fixedly installed on the top of the frame 1. The output end of the servo motor 61 is fixedly installed with a connecting rod 62 via a coupling. The end of the connecting rod 62 is rotatably installed with a connecting rod 63. Both the connecting rod 62 and the connecting rod 63 are made of high-strength alloy rods, which are firmly connected, rotate flexibly, and can withstand the weight of the tea tray 3 and the tea leaves without bending or deformation.

[0063] A guide rod 31 is fixedly installed on the rear side of the trough pot 3. The guide rod 31 is a cylindrical rod with a polished surface. A sleeve is fixedly connected to the end of the connecting rod 63. The sleeve is made of wear-resistant nylon material with a smooth inner wall. The sleeve is movably fitted on the outer wall of the guide rod 31 and slides with the guide rod 31, allowing it to slide freely along the guide rod 31.

[0064] During the tea processing stage, the tea-forming trough 3 is parallel to the frame 2. At this time, connecting rod 1 62 and connecting rod 2 63 are folded, and the sleeve is located in the middle of the guide rod 31, which does not affect the left and right reciprocating movement of the tea-forming trough 3.

[0065] To ensure that the sizing pan 3 is not interfered with by the turning mechanism 6 when it moves back and forth, the sleeve moves a greater distance on the guide rod 31 than the sizing pan 3 moves back and forth. In this way, when the sizing pan 3 moves left and right, the guide rod 31 will slide synchronously inside the sleeve. Since the sleeve has sufficient movement margin, it will not restrict the movement distance of the sizing pan 3, ensuring that the sizing process proceeds smoothly, while avoiding jamming or wear between the guide rod 31 and the sleeve.

[0066] After tea processing is completed, the drive mechanism 5 remains open, continuing to move the frame 2 and the tea-forming trough 3 back and forth. Then, the servo motor 61 is activated, driving the connecting rod 62 to rotate slowly clockwise. Since the end of the connecting rod 63 is slidably connected to the guide rod 31 via a sleeve, and the front end of the tea-forming trough 3 is rotatably installed in the mounting hole 21 of the frame 2 via a rotating shaft 32, the rotation of the connecting rod 62 will cause the connecting rod 63 to move synchronously, gradually increasing the angle between them. This, in turn, pushes the guide rod 31 upwards through the sleeve. The guide rod 31 then causes the tea-forming trough 3 to rotate slowly around the rotating shaft 32, gradually changing the tea-forming trough 3 from a horizontal state to an inclined state. Figure 10 As shown.

[0067] Since the frame 2 and the shaping pot 3 are rotatably connected by the rotating shaft 32, the frame 2 can still drive the shaping pot 3 to continue to move slightly left and right. The tilted shaping pot 3, combined with the inertial force of the left and right movement, causes the tea leaves in the U-shaped groove 33 to slide smoothly into the discharge trough 4 under the combined action of gravity and inertia, without any accumulation or residue. After all the tea leaves have fallen into the discharge trough 4, the servo motor 61 rotates in the opposite direction, driving the connecting rod 62 and the connecting rod 63 to fold and reset, driving the shaping pot 3 to rotate around the rotating shaft 32 to a horizontal state. At the same time, the drive mechanism 5 stops working, the heating plate 7 is turned off, and the operator takes out the finished tea leaves from the discharge trough 4, thus completing the entire tea shaping process.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.

10. A method of using a tea-scraping machine for a compound linkage mechanism, comprising using the tea-scraping machine for a compound linkage mechanism as described in claim 1, characterized in that, Includes the following steps: S1. Evenly put the tea leaves to be processed into each U-shaped groove (33) of the shaping pot (3), turn on the electric heating plate (7) to heat the shaping pot (3) to the preset temperature, heat and soften the tea leaves to prepare for subsequent shaping. S2. Start the drive mechanism (5), whose compound linkage transmission drives the frame (2) to move back and forth on the frame (1), and simultaneously drives the strip-groove pot (3) to move synchronously; S3, Shaping Process S3.1 When the tea-strip pot (3) moves to one side, the corresponding side arc plate (34) automatically unfolds under the inertia of the tea leaves, and the other side arc plate (34) closes, so that the tea leaves enter the angle formed by the arc plate (34) and the U-shaped groove (33) and are limited and squeezed. S3.2 When the tea-strip pan (3) moves in the opposite direction, the unfolded arc plate (34) closes and laterally squeezes the tea leaves, while the other arc plate (34) unfolds simultaneously to realize the tea leaves displacement and squeezing. S3.3, the tea-making pot (3) moves back and forth continuously, and the arc plate (34) cycles through opening and closing states, forming a continuous bidirectional extrusion on the tea leaves, similar to hand kneading, to quickly complete the shaping of the tea leaves; S4. After the tea leaves are shaped, keep the drive mechanism (5) running to drive the shaping pot (3) to move back and forth slightly, start the turning mechanism (6), and its compound linkage drive pushes the shaping pot (3) to turn around the rotating shaft (32) to the tilted state. Utilize the weight of the tea leaves and the inertia of the pot to make the finished tea leaves slide smoothly into the discharge trough (4) to complete the discharge.
