Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to an integrated device for transporting and mixing tea. Background Technology

[0002] In tea processing, the mixing process is a crucial step affecting the uniformity of the finished tea's quality. Traditional manual mixing methods are not only labor-intensive and inefficient, but also prone to tea breakage due to uneven handling, affecting the integrity of the tea leaves. Furthermore, open or semi-open mixing equipment makes it difficult to prevent tea leaves from prolonged contact with air during processing, easily leading to oxidation and deterioration. The intrusion of external dust and other impurities also poses a threat to the hygiene and safety of the tea. While some existing mechanized mixing devices alleviate the burden on manual labor to some extent, they often suffer from discontinuous processes, poor sealing, and insufficient control precision in the connection between feeding, mixing, and discharging. This results in tea leaves being easily spilled, contaminated, or mixed unevenly during transport. Especially when mixing different varieties and batches of tea, existing equipment struggles to achieve precise and controllable speed adjustment and process coordination, failing to achieve efficient, closed, and continuous operation while ensuring the physical quality of the tea. Therefore, it is necessary to design an integrated device that combines conveying and mixing functions, possesses good sealing and controllability, to improve the overall efficiency and quality stability of tea mixing processing.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0019] Please see Figures 1 to 5This embodiment provides a tea transportation and mixing integrated device, including: a first conveying component 1, a tea processing component 2, and a second conveying component 3. The first conveying component 1 includes a first conveyor belt 11, a first conveying hopper 12, and a first outer shell 13. The first conveyor belt 11 is disposed inside the first outer shell 13, and the first conveying hopper 12 is connected to one end of the first outer shell 13. The tea processing component 2 includes a processing cylinder 21, a drive unit 22, and a frame 23. The side wall of the processing cylinder 21 is provided with an inlet and an outlet, which are independent of each other. The drive unit 22 is connected to the processing cylinder 21. The processing cylinder 21 is connected by a drive. The processing cylinder 21 is placed inside the frame 23 and can rotate relative to the frame 23. When the processing cylinder 21 rotates to a preset angle, the feed port is placed below the output end of the first conveyor belt 11. The second conveying assembly 3 includes a second conveyor belt 31, a second conveying hopper 32 and a second outer shell 33. The second conveying hopper 32 is placed at the discharge port, and the second conveyor belt 31 is placed below the second conveying hopper 32. The second outer shell 33 includes a first side plate and a second side plate. The first side plate and the second side plate are arranged opposite each other on both sides of the second conveyor belt 31.

[0020] In this embodiment, the first conveying component 1 is responsible for the initial supply and lifting of materials. The first conveyor belt 11 is used to carry and transport tea leaves, and the first conveying hopper 12 receives the tea leaves and guides them to the starting end of the first conveyor belt 11. The first outer shell 13 is wrapped around the outside of the first conveyor belt 11 to form a closed channel, which mainly serves as protection and dust prevention.

[0021] The tea processing component 2 is the core of the mixing function. The processing cylinder 21, as a mixing container, has independently set inlet and outlet on its side wall, ensuring that the feeding and unloading processes do not interfere with each other in space and time. The drive unit 22 provides power for the rotation of the processing cylinder 21. The frame 23 serves as the overall support structure, and the processing cylinder 21 is rotatably installed inside it. The drive unit 22 controls its rotation to a specific preset angle. When the processing cylinder 21 rotates to the point where the inlet is aligned with the output end of the first conveyor belt 11, the material can be smoothly transferred in.

[0022] The second conveying assembly 3 is responsible for receiving and transporting the mixed finished product. The second conveying hopper 32 is placed below the discharge port of the processing cylinder 21 to receive the material. The second conveyor belt 31 is used for subsequent horizontal conveying. The second outer shell 33 is composed of a first side plate and a second side plate arranged opposite to each other, forming barriers on both sides of the conveying channel to effectively prevent tea leaves from scattering during the conveying process.

[0023] Preferably, the outer shells of each component can be made of materials that meet food hygiene requirements to ensure the hygiene and safety of tea during processing. Specifically, components that come into direct contact with tea, such as the processing cylinder 21, the first outer shell 13, and the second outer shell 33, can preferably be made of 304 stainless steel, which has good corrosion resistance and meets food hygiene and safety standards. The connections between components, such as the inlet and outlet of the processing cylinder 21, can be sealed with rubber sealing rings or labyrinth sealing structures to ensure that the sealing level of key areas reaches the IP65 standard, thereby preventing the intrusion of external dust and moisture to the greatest extent and ensuring the purity and quality of tea during transportation and blending.

[0024] During operation, the tea leaves to be mixed are fed into the first conveyor hopper 12 and transported to its output end by the first conveyor belt 11. The drive unit 22 drives the processing cylinder 21 to rotate. When its inlet rotates to a preset position directly below the output end of the first conveyor belt 11, the tea leaves fall into the processing cylinder 21 under gravity. The drive unit 22 continues to operate, causing the processing cylinder 21 to tumble according to set parameters, ensuring thorough mixing of the tea leaves inside. After the mixing process is completed, the processing cylinder 21 is rotated so that its outlet faces downward and aligns with the second conveyor hopper 32. The evenly mixed tea leaves are discharged through the outlet, fall into the second conveyor hopper 32, and then onto the second conveyor belt 31, finally being transported to the designated workstation.

[0025] This embodiment integrates conveying and mixing functions into a single device, achieving continuous and automated tea processing from input to output. It simplifies material transfer procedures and significantly reduces manual intervention and material exposure time between processes. This embodiment effectively improves production efficiency and reduces labor intensity. The closed-loop flow path minimizes external contamination and quality degradation caused by moisture absorption and oxidation during processing. Independent inlets and outlets ensure the independence and continuity of the mixing process, guaranteeing stable uniformity of the final product and providing a reliable foundation for clean and standardized tea processing.

[0026] In some embodiments, the frame 23 includes a first support column, a second support column, and a plurality of legs. The plurality of legs are distributed circumferentially along the processing cylinder 21. The first support column and the second support column are disposed on the plurality of legs and are disposed opposite to each other below the processing cylinder 21. The processing cylinder 21 has a first flange and a second flange. The tea processing assembly 2 further includes: a first roller group 231 and a second roller group 232. The first roller group 231 is disposed on the first support column and includes at least two first rollers. The first flange is adapted to the first rollers so that the processing cylinder 21 rolls relative to the frame 23. The second roller group 232 is disposed on the second support column and includes at least two second rollers. The second flange is adapted to the second rollers so that the processing cylinder 21 rolls relative to the frame 23.

[0027] In this embodiment, the frame 23 provides stable and flexible rotational support for the processing cylinder 21. Multiple support legs are distributed circumferentially along the processing cylinder 21, forming a stable bottom foundation for the entire frame 23. The first and second support columns are positioned opposite each other on the multiple support legs below the processing cylinder 21, jointly bearing the main load-bearing and support functions. The first and second flanges on the processing cylinder 21 respectively cooperate with the first roller assembly 231 mounted on the first support column and the second roller assembly 232 mounted on the second support column. The fitting structure between the flanges and rollers effectively distributes and transfers the weight of the processing cylinder 21 to the support columns, while simultaneously converting the sliding friction between the processing cylinder 21 and the frame 23 into rolling friction. Preferably, the rollers are made of wear-resistant materials to extend their service life and ensure smooth rotation. This design allows the processing cylinder 21 to roll smoothly relative to the frame 23 under the drive of the drive unit 22, providing a stable motion basis for the uniform mixing of tea leaves inside the cylinder.

[0028] This embodiment utilizes a frame 23 structure comprised of legs, support columns, and roller sets to provide precise support and guidance for the rotational movement of the processing cylinder 21. When the drive unit 22 rotates the processing cylinder 21, its first and second flanges roll on the first roller set 231 and the second roller set 232, respectively, evenly distributing the weight of the cylinder and significantly reducing rotational resistance. This effectively limits the unexpected radial and axial displacement of the processing cylinder 21, ensuring its operational stability and concentricity during the mixing process and preventing the adverse effects of shaking or deviation on the mixing effect and equipment lifespan. This embodiment not only guarantees the long-term reliability of the processing cylinder 21 but also improves transmission efficiency by reducing frictional losses, laying a solid mechanical foundation for the smooth and efficient operation of the entire device.

[0029] In some embodiments, the processing cylinder 21 is provided with a first roller at its end, and the first roller is connected to the drive unit 22 for transmission. The tea processing assembly 2 also includes a first driving wheel 24, a first driven wheel 25 and a first conveyor belt 26. The first driving wheel 24 is sleeved on the output end of the drive unit 22; the first driven wheel 25 is sleeved on the first roller; and the first conveyor belt 26 is sleeved on the first driving wheel 24 and the first driven wheel 25.

[0030] In this embodiment, the power transmission system uses belt drive to connect the drive unit 22 and the processing cylinder 21. A first roller at the end of the processing cylinder 21 serves as the power input shaft. A first driving wheel 24 is mounted on the output end of the drive unit 22, and a first driven wheel 25 is fixed to the first roller. The two are connected by a first conveyor belt 26, effectively buffering vibrations and impacts generated during motor startup and operation, and providing overload protection. Preferably, the first conveyor belt 26 can be made of a material with appropriate elasticity and wear resistance to ensure smooth and durable transmission. This structure reliably transmits the rotational motion of the drive unit 22 to the processing cylinder 21, which is crucial for achieving its tumbling and mixed motion.

[0031] To further enhance the automation level and mixing accuracy of the equipment, the drive unit 22 can preferably be a GH50 horizontal geared motor with variable frequency speed control. This drive unit 22 can be electrically connected to a programmable logic controller (PLC), which allows for precise setting and stepless adjustment of the drive unit 22's rotation speed. This enables accurate control of the tumbling rate of the processing drum 21 according to different tea varieties and mixing process requirements, ensuring uniform mixing. This control method provides rapid response and stable operation, effectively guaranteeing the mixed quality of the tea.

[0032] When the drive unit 22 is started, its output drives the first driving wheel 24 to rotate, and transmits power to the first driven wheel 25 mounted on the first roller via the first conveyor belt 26, thereby driving the processing cylinder 21 to rotate around its axis. Belt drive has the characteristics of buffering and absorbing vibration, smoothly transmitting torque and reducing direct impact on the processing cylinder 21. This embodiment simplifies the transmission structure, facilitates installation and maintenance, and its inherent slippage characteristic can protect the equipment from overload, improving the reliability and service life of the entire transmission system and ensuring the stable operation of the processing cylinder 21.

[0033] In some embodiments, the processing cylinder 21 has a receiving cavity for holding tea leaves; the tea processing assembly 2 also includes a plurality of stirring rods, which are arranged on the inner wall of the processing cylinder 21 in a preset distribution pattern and extend toward the receiving cavity; the preset distribution pattern is configured to be spirally distributed from front to back along the axial direction of the processing cylinder 21; or, the preset distribution pattern is configured to be evenly distributed in an array along the circumferential direction of the processing cylinder 21.

[0034] In this embodiment, the accommodating cavity inside the processing cylinder 21 is a space for containing and mixing tea leaves. To further improve the mixing effect, multiple stirring rollers are provided on the inner wall of the processing cylinder 21, extending towards the center of the accommodating cavity. The preset distribution methods include a spiral distribution from front to back along the axial direction of the processing cylinder 21 and an equidistant array distribution along the circumference of the processing cylinder 21. When the multiple stirring rollers are spirally distributed from front to back along the axial direction of the processing cylinder 21, they can generate a continuous axial propulsion and radial scattering combined effect on the tea leaves when the cylinder rotates, promoting the circulation and mixing of materials in the front and back directions within the cylinder. When the multiple stirring rollers are equidistantly arrayed along the circumference of the processing cylinder 21, the focus is on uniformly cutting and turning the tea leaves when the cylinder rotates, which is especially beneficial for breaking up any tea leaves that may clump together.

[0035] Preferably, the stirring rollers can be rectangular components to enhance their impact and dispersion effect on the tea leaves. When the processing cylinder 21 rotates, the stirring rollers effectively impact any potentially clumped tea leaves, breaking them down to their normal size. Specifically, when the drive unit 22 drives the processing cylinder 21 to alternate between forward and reverse rotation, the spiral or circumferentially arrayed stirring rollers continuously change the direction and path of agitation on the tea leaves, enabling multi-dimensional and highly uniform mixing of different tea varieties within the accommodating cavity.

[0036] When the processing cylinder 21 rotates under the drive of the drive unit 22, the stirring rollers fixed to its inner wall move accordingly. The spirally distributed stirring rollers guide the tea leaves axially and ensure full diffusion, preventing localized accumulation; the circumferentially equidistant stirring rollers act like multiple stirring blades, repeatedly agitating the passing tea leaves. Both distribution methods effectively break up the flow layer of the tea leaves, increasing the contact opportunities between tea leaves of different qualities, thereby significantly improving the uniformity and efficiency of mixing. This embodiment, by optimizing the distribution of the stirring rollers, strengthens the hybrid dynamics process within the processing cylinder 21, ensuring the consistency and stability of the final tea product quality.

[0037] In some embodiments, the first conveyor belt 11 is configured to be formed by chain connection; the first conveying assembly 1 also includes a plurality of first conveying troughs 14, the plurality of first conveying troughs 14 being spaced apart on the first conveyor belt 11, the first conveying troughs 14 being rotatable relative to the first conveyor belt 11 to a preset angle, and the first conveying troughs 14 being used to hold tea leaves to be mixed.

[0038] In this embodiment, the first conveyor belt 11 is constructed using a chain connection, which provides high strength and durability, making it suitable for stable material transport on inclined or Z-shaped paths. To further optimize the conveying process, multiple first conveying troughs 14 are spaced apart on the first conveyor belt 11 to hold tea leaves during transport, preventing them from slipping or scattering. Furthermore, the first conveying troughs 14 can rotate relative to the first conveyor belt 11 to a preset angle. Preferably, this preset angle can be set so that when the conveying trough reaches the output end of the first conveyor belt 11, it automatically tilts to smoothly pour the tea leaves into the feed inlet of the processing cylinder 21, achieving targeted and directional material delivery.

[0039] When the first conveyor belt 11 operates, the first conveyor trough 14 containing tea leaves moves accordingly. Upon reaching a specific position at the output end of the first conveyor belt 11, the conveyor trough rotates relative to the conveyor belt to a preset tilting angle, accurately pouring the tea leaves into the feed inlet of the processing cylinder 21 below. This process achieves automated and precise transfer of tea leaves from the conveyor belt to the processing cylinder 21, avoiding spillage, dust, and uneven feeding problems that may occur with manual feeding or simple slippage. This embodiment not only improves the automation and efficiency of the feeding process, but more importantly, the controllable tilting action ensures the accuracy and cleanliness of the feeding, laying the foundation for subsequent uniform mixing.

[0040] In some embodiments, the first conveying hopper 12 is an inverted trapezoid; the first housing is Z-shaped; and the shape of the first conveyor belt 11 is adapted to the shape of the first housing.

[0041] In this embodiment, the first conveying hopper 12 adopts an inverted trapezoidal structure, with its larger opening facing upwards to easily receive the tea leaves, and its smaller opening facing downwards to facilitate the concentration of materials and their smooth descent onto the first conveyor belt 11, conforming to the natural flow characteristics of materials. The first housing is designed in a Z-shape, enabling the first conveyor belt 11 to achieve a path of first lifting and then horizontal conveying, in order to adapt to the overall layout requirements of the equipment; the shape of the first conveyor belt 11 is adapted to the Z-shaped first housing, ensuring that the conveyor belt can run smoothly within the housing and complete the specific trajectory conveying of the tea leaves.

[0042] The inverted trapezoidal hopper facilitates material collection and flow guidance, while the Z-shaped shell and compatible conveyor belt work together to lift and transfer tea leaves from a low to a high position. This compact structure effectively utilizes space and makes the tea leaf conveying path more aligned with actual process requirements, improving equipment integration and material flow efficiency.

[0043] In some embodiments, the tea processing assembly 2 further includes a first feed cover and a first discharge cover, wherein the first feed cover covers the feed inlet and the first discharge cover covers the discharge outlet.

[0044] In this embodiment, the first feed cover is used to cover the feed inlet of the processing cylinder 21, and the first discharge cover is used to cover the discharge outlet, respectively closing the corresponding openings during non-feeding or non-discharge periods. Preferably, the first feed cover and the first discharge cover can be made of metal plates that match the material of the processing cylinder 21, and can be opened and closed by means of hinges or slide rails, so as to isolate the accommodating cavity of the processing cylinder 21 from the external environment and form a relatively closed mixing space.

[0045] When the processing cylinder 21 needs to be fed, the first feed cover opens and closes immediately after the tea leaves enter. During the mixing process, both the first feed cover and the first discharge cover remain closed. When discharging, the first discharge cover opens. The opening and closing actions of the first feed cover and the first discharge cover are linked to the control of the drive unit 22 and the conveying assembly, effectively preventing the tea leaves from absorbing moisture and oxidizing due to prolonged exposure during the mixing process, while also blocking the intrusion of external dust and impurities, thus ensuring the hygiene and quality of the tea leaves. This embodiment significantly improves the sealing of the processing process through a simple mechanical structure, providing a key guarantee for obtaining high-quality blended tea products.

[0046] In some embodiments, the second conveying assembly 3 further includes: a servo motor, a second discharge cover 34, a rack 35, and a gear 36. The servo motor is disposed on one side of the second conveying hopper 32. The second discharge cover 34 is disposed on the second conveying hopper 32 and is movable relative to the second conveying hopper 32. The rack 35 is disposed at the bottom of the second discharge cover 34. The gear 36 is connected to the servo motor and meshes with the rack 35 to adjust the opening of the second discharge cover 34.

[0047] In this embodiment, a servo motor, serving as the drive source, is located on one side of the second conveying hopper 32 and possesses precise speed and position control capabilities. A second discharge cover 34 is located in the discharge port area of ​​the second conveying hopper 32 and can move relative to the hopper to adjust its opening. To achieve this, a rack 35 is provided at the bottom of the second discharge cover 34. A gear 36, connected to the servo motor, meshes with the rack 35, forming a transmission pair that converts the motor's rotational motion into the linear motion of the cover.

[0048] Furthermore, the servo motor can accept commands from the system control unit (such as a PLC) to achieve precise setting and automatic adjustment of the opening degree. Preferably, the servo motor can be a 60BL series brushless DC motor with excellent response performance, working in conjunction with a programmable logic controller. It can receive precise command signals and then control the second discharge cover plate 34 to achieve rapid and smooth linear movement through the meshing transmission of gear 36 and rack 35, so as to precisely adjust the opening degree of the discharge port. This not only reduces manual operation but also ensures stable and controllable discharge flow.

[0049] When it is necessary to control the flow rate of tea leaves falling from the second conveyor hopper 32 onto the second conveyor belt 31, the servo motor rotates according to the command, driving the gear 36 to rotate. The gear 36 meshes with the rack 35 fixed at the bottom of the second discharge cover 34, thereby pushing or pulling the second discharge cover 34 relative to the second conveyor hopper 32, changing the opening size of the discharge port. By precisely controlling the rotation angle of the servo motor, stepless and precise adjustment of the discharge cover opening can be achieved, allowing the discharge flow rate to be flexibly controlled according to the needs of subsequent processes, avoiding material accumulation or interruption on the second conveyor belt 31. This embodiment realizes the automation and precision of the discharge process, ensuring the stability and continuity of subsequent conveying, and providing a foundation for a higher level of process control for the entire system.

[0050] In some embodiments, there are two racks 35, which are arranged opposite to each other on both sides of the second discharge cover plate 34; the number of gears 36 corresponds one-to-one with the number of racks 35; the second conveying assembly 3 also includes a connecting shaft 37, which passes through the two gears 36 in sequence, and is connected to a servo motor for transmission.

[0051] In this embodiment, two racks 35 are arranged opposite each other at the bottom of the two sides of the second discharge cover 34. Correspondingly, two gears 36 are also provided, meshing with the racks 35 on both sides respectively. To ensure that the two gears 36 can rotate synchronously and to prevent the second discharge cover 34 from jamming or deviating during movement, a connecting shaft 37 is added, passing through the two gears 36 sequentially to rigidly connect them, and then drivingly connecting to the output end of the servo motor. The power of the servo motor drives the two gears 36 to rotate simultaneously through the connecting shaft 37.

[0052] When the servo motor starts, power is synchronously transmitted to the gears 36 on both sides via the connecting shaft 37. The two gears 36 then drive the racks 35 on both sides that mesh with them, thereby jointly pushing or pulling the second discharge cover 34 to move smoothly. This dual-sided synchronous drive method ensures that the second discharge cover 34 is subjected to balanced force, effectively preventing problems such as torsion, jamming, or accelerated wear caused by unilateral force during movement. This embodiment significantly improves the smoothness, reliability, and service life of the discharge cover opening adjustment mechanism, ensuring accurate and stable flow control.

[0053] In some embodiments, the second conveying assembly 3 further includes a plurality of partitions 311, which are spaced apart on the second conveyor belt 31.

[0054] In this embodiment, the partition 311 is installed perpendicular to the surface of the second conveyor belt 31, dividing the working surface of the second conveyor belt 31 into several independent sections to prevent tea leaves from mixing or slipping to both sides on the conveyor belt due to inertia or belt tilt. Preferably, the partition 311 can be made of a material with a certain hardness and wear resistance to withstand the impact of the material.

[0055] When the mixed tea leaves fall from the second conveyor hopper 32 to the second conveyor belt 31, the spaced partitions 311 separate the tea leaves into different sections for conveying. This effectively avoids unnecessary secondary mixing or accumulation of tea leaves from different batches or regions during the conveying process, while also reducing the risk of tea leaves scattering from the edge of the belt. This ensures the orderliness of the conveying process and the integrity of the materials, providing convenience for subsequent packaging or storage processes.

[0056] By adopting the above technical solutions, this utility model differs from the prior art and has the following beneficial effects: By organically combining the first conveying component 1, the tea processing component 2, and the second conveying component 3, a continuous closed-loop operation system from feeding to discharging is constructed.
