Description

Technical Field

[0001] This invention relates to the field of tea processing machinery technology, and in particular to an integrated equipment for tea kneading, shaping, and finishing. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] my country's premium green tea industry continues to expand, with distinctive teas such as Mao Feng and Lu'an Guapian occupying a place in the high-end tea market due to their unique appearance and rich flavor. After processing (kill-green), the core shaping processes—rolling, shaping, and final firing—determine the finished product's appearance, aroma, taste, and shelf life. Currently, the domestic premium tea processing industry exhibits a polarized development pattern: widespread single-machine automation and a scarcity of fully integrated intelligent continuous production lines. Large-scale tea enterprises have a single-machine automation rate approaching 70%, but only 7% to 8% have built integrated intelligent continuous production lines. Small and medium-sized tea factories in counties still generally use intermittent, segmented single-machine operations, and the overall penetration rate of fully automated, non-landing intelligent production lines is less than 3%.

[0004] The existing continuous green tea production line technology mainly targets bulk tea raw materials. The mainstream process route is automatic feeding and withering → continuous withering / steam fixation / shaping fixation → multi-stage drying → air separation and grading. This complete production line has obvious process defects: it completely omits the rolling and shaping process that is essential for high-end famous teas, and the degree of fixation is generally insufficient. It relies solely on the external force of the shaping machine to form the tea leaves, resulting in loose tea strips, insufficient breakage of internal substances, lack of freshness and mellowness in the tea soup, reduced brewing endurance, and significantly shortened shelf life. It can only meet the production of standardized, affordable bulk famous teas and cannot meet the quality requirements of high-quality, fine handmade teas.

[0005] For premium green teas like Mao Feng and Liuan Guapian, which require kneading and shaping, the core shaping processes (strip preparation, kneading, and final roasting) currently rely on separate, single-machine bionic roasting equipment for segmented processing. Tea leaves are manually transferred between these machines, making continuous, interconnected operations via belt conveyors difficult. This is especially true for the kneading and shaping of delicate single-bud or one-bud-one-leaf raw materials, where existing equipment cannot achieve integrated continuous feeding, kneading, and final roasting. The entire process requires manual handling, spreading, and transferring of tea leaves, resulting in high labor intensity, low production efficiency, and frequent tea leaf transfers that easily cause breakage, dull color, and poor consistency in finished product quality.

[0006] Meanwhile, the investment threshold for existing mature continuous production lines for famous and high-quality teas is extremely high. The cost of a complete intelligent continuous production line for primary processing ranges from 1.8 million to 6 million yuan, and the total investment for supporting integrated digital workshops generally exceeds 10 million yuan. However, the annual output value of most small and medium-sized tea factories in counties across the country is less than 10 million yuan, and the equipment investment recovery period is long. Without special financial subsidies, enterprises cannot afford to invest in production line transformation. Existing continuous equipment can only be implemented in government-supported projects of leading enterprises. There are significant cost barriers to the intelligent upgrading of small and medium-sized tea factories.

[0007] In summary, the industry urgently needs a low-cost, integrated, and continuous processing equipment that can simultaneously complete the three core shaping processes of leaf shaping, rolling, and final firing. This equipment should balance the procurement costs of small and medium-sized tea factories with the handcrafted quality of high-end premium green tea, and address the technical shortcomings of existing segmented single-machine and bulk tea production lines, such as process fragmentation, quality decline, high investment, and inability to continuously roll and shape the leaves. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings mentioned above by providing an integrated equipment for tea rolling, shaping, and finishing.

The two drive rings can be twisted in opposite directions to clamp the slide sleeve, thereby locking and fixing the slide sleeve and sliding rod onto the rotating shaft.

[0013] Furthermore, the sliding sleeve includes a sleeve body and two contact blocks; the sleeve body is slidably sleeved on the outside of the rotating shaft, and a ring plate is circumferentially arranged on the outer wall of the middle part of the sleeve body; the contact blocks are annular structures, and the two contact blocks are slidably sleeved on both ends of the sleeve body respectively, and a friction pad is provided between the contact blocks and the drive ring.

The pressing block is used to press the inclined block and drive the contact block to move away from the sleeve. The ring plate is provided with a pushing component, which is used to push the extrusion block, causing the extrusion block to move radially along the rotating shaft in the pushing groove, thereby causing the contact block to clamp the friction pad with the drive ring.

[0014] Furthermore, the adjustment mechanism is provided in two sets, which correspond to the first processing area and the second processing area respectively, and are used to adjust the rotation angle of the broom handle corresponding to the first processing area and the second processing area respectively.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 6 This invention discloses an integrated equipment for tea kneading, shaping, and roasting, including a tank 1, a roasting component 2, and a heating component; The tank 1 has a horizontally arranged cylindrical processing cavity inside. One end of the tank 1 has an inlet 11 and the other end has an outlet 12. The processing cavity is divided into a first processing area 13 and a second processing area 14 along the axial direction. The first processing area 13 is adjacent to the inlet 11 and is used to complete the tea rolling and shaping process. The second processing area 14 is adjacent to the outlet 12 and is used to complete the tea drying and shaping process. The frying component 2 includes a rotating shaft 21 that runs horizontally through the inside of the tank 1. Both ends of the rotating shaft 21 are rotatably adapted to the tank 1. Multiple frying brooms 3 are fixed on the rotating shaft 21. The rotating shaft 21 is driven to rotate through the drive component 4, which drives the rotating shaft 21 to rotate and causes the frying brooms 3 to circulate inside the processing chamber. The drive component 4 kneads and shapes the tea leaves in the first processing zone 13 and continuously stirs and frys the tea leaves in the second processing zone 14. At the same time, the processed tea leaves are pushed to the discharge port 12 for discharge. The heating element (not shown in the figure) is installed on the inner wall of the tank 1 and can simultaneously control the temperature of the first processing zone 13 and the second processing zone 14 in segments, providing a suitable temperature environment for the entire process of kneading, shaping and finishing.

[0024] This application is suitable for processing tender and high-quality green tea raw materials such as single buds and one bud and one leaf. Because these fresh leaves are delicate, when the broom 3 continuously contacts the tea leaves and drives the tea leaves to circulate in a single fixed direction, the dual processes of kneading and shaping can be achieved simultaneously. Among them, the kneading process relies on the friction and squeezing action between the broom and the tea leaves to gently break down the tea leaf cells, so that the tea juice can be evenly exuded. The internal quality transformation can be achieved without additional heavy kneading equipment. At the same time, the tea leaves are continuously rubbed and combed along a fixed trajectory, and the shaping is completed simultaneously. The tea leaves are then transferred to the final drying area for drying and aroma enhancement.

[0025] During operation, tender fresh leaves, either single buds or one bud and one leaf, after being processed by fixing, are fed into the first processing zone 13 of the cylindrical processing chamber through the feed inlet 11 of the tank 1. The power unit drives the rotating shaft 21 to continuously rotate the multi-link broom, which continuously squeezes, kneads, and combs the tea leaves in the first processing zone 13 (simulating the action of manually stir-frying tea leaves with a broom, turning the tea leaves in a fixed direction). Simultaneously, the appropriate temperature provided by the inner wall heating component completes the kneading and shaping of the tea leaves, forming regular strips. The tea leaves move with the broom ( The broom (with a certain angle of inclination) rotates continuously and gradually conveys the tea leaves to the second processing area 14. After entering the final roasting stage, the heating components continuously supply a stable heat source. The tea leaves are stir-fried and turned by the broom 3, and excess moisture inside the tea leaves is evenly removed, completing the final roasting process to enhance aroma and shape. The broom 3 continuously pushes the shaped dry tea leaves axially, and finally the processed tea leaves are continuously sent out from the discharge port 12 at the end of the tank 1. After discharge, the tea leaves can be directly transferred to the dryer for final drying. The entire set of kneading, shaping, and final roasting processes do not require manual transfer, realizing continuous integrated processing.

[0026] This application integrates the three core shaping processes of kneading, shaping, and final roasting into a single tank 1 unit, replacing the traditional multi-unit, segmented operation mode. This eliminates the need for manual transfer and feeding between equipment, significantly reducing labor intensity and shortening processing time. It enables continuous tea production without touching the ground, effectively improving overall production efficiency. The equipment relies on a single rotating shaft 21 linked with a broom to simultaneously complete kneading and shaping, as well as final roasting. Combined with the segmented heating structure on the inner wall of tank 1, it can precisely match the temperature required for different processes, completely replicating the kneading and roasting process mechanism of handmade tea. The machine has a compact structure and a high degree of integration, significantly reducing equipment manufacturing costs and factory floor space requirements. It has a lower investment threshold and can be adapted for the purchase and renovation of small and medium-sized tea factories in counties, solving the financial barrier problem of intelligent upgrading for small and medium-sized tea enterprises. It is suitable for the large-scale processing of single-bud, one-bud-one-leaf high-end famous green teas, as well as specialty teas such as Lu'an Melon Seed and Mao Feng, with a wide range of applications.

[0027] Preferably, the rotation center of the rotating shaft 21 can be located below the central axis of the cylindrical processing cavity; this arrangement allows the kneading force applied to the tea leaves during the rotation of the frying broom 3 to gradually decrease, with a larger force used to fully knead and shape the leaves in the early stage, and a gentle combing and shaping in the later stage, which is more conducive to completing the tea kneading and shaping process simultaneously.

[0028] Preferably, the driving component 4 can be a drive motor in the prior art, which can directly drive the rotating shaft 21 to rotate, or drive the rotating shaft 21 to rotate through a belt pulley or sprocket transmission mechanism.

[0029] In one embodiment, the broom 3 includes a broom handle 31 and a broom head 32; one end of the broom handle 31 is fixedly connected to the broom head 32, and the other end is mounted on a rotating shaft 21 and can rotate around its own axis; the rotating shaft 21 is provided with an adjustment mechanism 5, which is used to limit the rotation angle of the broom handle 31 and lock the relative position between the broom handle 31 and the rotating shaft 21.

[0030] This application utilizes a broom handle 31 that can rotate around its own axis and an adjustment mechanism 5 to adjust the angle of attack of the working surface of the broom head 32, thereby changing the amount of tea material caught and clamped between the broom head 32 and the inner wall of the tank 1, thus controlling the overall kneading effect. When the board surface is directly facing the direction of revolution, it can retain more tea leaves to achieve full kneading and shaping. After the broom head 32 deflects, some tea leaves slide along the board surface and escape from the squeezing gap, weakening the overall kneading effect and reducing the probability of breakage of tender buds and leaves. The change in the angle of attack of the broom head 32 can also adjust the axial pushing force, synchronously controlling the residence time and discharge speed of tea leaves in each processing area, adapting to different raw materials and processing conditions without changing parts. After the adjustment mechanism 5 locks the angle of attack of the broom handle 31, it can stably maintain the angle of attack of the working surface of the broom head 32, ensuring the stability of the tea kneading and conveying state during batch processing and improving the consistency of the finished tea quality.

[0031] Preferably, a guide sleeve 211 is provided on the rotating shaft 21 at the position of each broom handle 31 to support and guide the rotating shaft 21.

[0032] In one embodiment, the rotating shaft 21 is configured as a hollow structure; the broom handle 31 is rotatably engaged with the rotating shaft 21, and one end of the broom handle 31 extends into the inner cavity of the rotating shaft 21 and is fixedly connected to the first bevel gear 33; The adjustment mechanism 5 includes an adjustment shaft 51 rotatably mounted in the inner cavity of the rotating shaft 21, and a second bevel gear 52 that meshes with the first bevel gear 33 is fixedly mounted on the adjustment shaft 51; at least one spiral groove 511 is provided on the outer wall of the adjustment shaft 51. The adjustment mechanism 5 also includes a sliding rod 53, one end of which extends into the spiral groove 511 and slides in cooperation with the spiral groove 511, and the other end of which passes through the rotating shaft 21; the rotating shaft 21 is provided with a clearance groove 212 for the sliding rod 53 to move linearly along the axis of the rotating shaft 21; the rotating shaft 21 is also provided with a fixing component 6, which is used to lock the axial displacement position of the sliding rod 53 relative to the rotating shaft 21.

[0033] In this application, the linear movement of the sliding rod 53 along the axial direction of the rotating shaft 21 is converted into the rotational motion of the adjusting shaft 51 by means of the spiral groove 511. Then, the first bevel gear 33 and the second bevel gear 52, which mesh with each other, drive the broom handle 31 to rotate on its own axis. The angle of attack of the working surface of the broom head 32 can be adjusted by operating the sliding rod 53 on the outside of the rotating shaft 21 without disassembling the canister 1. The adjustment operation is simple and convenient. After the adjustment is in place, the axial position of the sliding rod 53 is locked by the fixing component 6, so as to realize the position locking of the entire transmission mechanism and stably maintain the working angle of attack of the broom head 32.

[0034] In one embodiment, the fixing component 6 includes a sliding sleeve 61 that is slidably sleeved on the outside of the rotating shaft 21, and the sliding sleeve 61 is connected to the sliding rod 53; a drive ring 62 is provided on both axial sides of the sliding sleeve 61, the drive ring 62 is provided with an internal thread, and the outer wall of the rotating shaft 21 is provided with an external thread that matches the internal thread of the drive ring 62. Twisting one of the drive rings 62 can push the slide sleeve 61 toward the other drive ring 62. The two drive rings 62 can be twisted in opposite directions to clamp the slide sleeve 61, thereby locking and fixing the slide sleeve 61 and the sliding rod 53 onto the rotating shaft 21.

[0035] This application employs a locking structure in which a double-sided threaded drive ring 62 clamps the sliding sleeve 61. The axial positioning of the sliding sleeve 61 and the sliding rod 53 is achieved through thread engagement. Both locking and releasing operations can be completed outside the rotating shaft 21, making operation simple. The locking method of the double-sided drive ring 62 clamping against each other can provide a reliable axial limiting constraint force, enabling the sliding sleeve 61 to be locked and fixed on the rotating shaft 21 at any position. It has high adjustment accuracy and can adapt to the locking requirements of the sliding rod 53 under different adjustment strokes. The structure is simple and reliable.

[0036] In one embodiment, the sliding sleeve 61 includes a sleeve body 611 and two contact blocks 612; the sleeve body 611 is slidably sleeved on the outside of the rotating shaft 21, and a ring plate 613 is circumferentially arranged on the outer wall of the middle part of the sleeve body 611; the contact blocks 612 have an annular structure, and the two contact blocks 612 are respectively slidably sleeved on both ends of the sleeve body 611, and a friction pad (not shown in the figure) is provided between the contact blocks 612 and the drive ring 62. The contact block 612 is provided with a plurality of inclined blocks 614 on the side facing the ring plate 613. The ring plate 613 is provided with a pushing groove 615 corresponding to the position of each inclined block 614. The end of the inclined block 614 can extend into the pushing groove 615. The pushing groove 615 is equipped with a pressing block 616 adapted to the inclined block 614. The pressing block 616 is used to press the inclined block 614, driving the contact block 612 to move away from the sleeve 611. The ring plate 613 is provided with a pushing component 617, which is used to push the extrusion block 616, causing the extrusion block 616 to move radially along the rotating shaft 21 in the pushing groove 615, thereby causing the contact block 612 to clamp the friction pad with the drive ring 62.

[0037] In this application, the sliding sleeve 61 drives the extrusion block 616 to move radially through the pushing component 617. The radial force is converted into the axial thrust of the contact block 612 by the inclined transmission between the extrusion block 616 and the inclined block 614, thereby pressing the friction pad between the contact block 612 and the drive ring 62. The large friction force generated by the friction pad is used to lock and position the sliding sleeve 61. The friction pad can increase the friction damping between the contact block 612 and the drive ring 62, effectively resisting the vibration during the operation of the equipment and the impact of tea materials, preventing the sliding sleeve 61 and the sliding rod 53 from axial movement, and providing a good locking effect. It can ensure the long-term stability of the broom handle 31 adjustment angle, and is convenient for assembly and debugging, and simple for maintenance and operation.

[0038] Preferably, the friction pad can be fixed on the contact block 612 and / or the drive ring 62; preferably, the friction pad can be a rubber pad.

[0039] Preferably, the pushing component 617 is a bolt that is threaded to fit the ring plate 613, and the bottom end of the bolt can be rotatably fitted to the pressing block 616.

[0040] Preferably, one end of the rotating shaft 21 corresponding to the fixing component 6 can extend out of the tank 1, and the fixing component 6 can be placed outside the tank 1; of course, the fixing component 6 can also be placed inside the tank 1 (when the fixing component 6 is inside the tank 1, the tank 1 can be opened).

[0041] In one embodiment, the adjustment mechanism 5 is provided in two sets, located at both ends of the rotating shaft 21 respectively. The two sets of adjustment mechanisms 5 correspond to the first processing area 13 and the second processing area 14 respectively, and are used to adjust the rotation angle of the broom handle 31 corresponding to the first processing area 13 and the second processing area 14 respectively.

[0042] This application sets up two independent adjustment mechanisms 5 to individually control the rotation angle of the broom handle 31 in the first processing zone 13 and the second processing zone 14. The working angle of the broom head 32 in the corresponding area can be set according to the process requirements of different processes such as kneading and shaping and frying. The working posture of the first processing zone 13 can be adjusted to be suitable for kneading and shaping tea leaves, retaining enough tea leaves to achieve full kneading and shaping. The posture of the broom in the second processing zone 14 can be switched to be suitable for frying and discharging tea leaves, accelerating the tea leaf conveying speed. The broom postures of the two processing zones do not interfere with each other and do not require compromise, which can better match the differentiated process objectives of different processing zones of the integrated equipment.

[0043] In one embodiment, the inner side of the tank body 1 is provided with a plurality of protrusions 15 corresponding to the processing cavity; each protrusion 15 extends along the axial direction of the processing cavity, and the plurality of protrusions 15 are arranged in a ring around the inner wall of the tank body 1.

[0044] In this application, the axially protruding strips 15 arranged in a ring around the inner wall of the can 1 can increase the frictional resistance between the inner wall of the can 1 and the tea leaves. When the tea leaves move under the action of the broom head 32, the protruding strips 15 can block and impede the tea leaves, improve the kneading and shearing effect between the broom head 32, the tea leaves and the can wall, strengthen the ability of the tea leaves to knead and shape, promote the destruction of tea cell and the extraction of tea juice, and at the same time reduce the phenomenon of the tea leaves slipping and spinning in vain along with the broom head 32, so that the tea leaves can be turned and kneaded more thoroughly, taking into account the heat exchange effect of shaping and frying in the final stage, which helps the tea leaves to be heated evenly, improves the tightness of the finished product strips and the overall processing quality.

[0045] In one embodiment, a frame 7 is provided at the bottom of the tank 1 for supporting and fixing the tank 1.
