Description

Technical Field

[0001] This utility model relates to the technical field of kneading devices, and in particular to a kneading device for tea processing. Background Technology

[0002] The rolling process in tea processing is a key step in shaping the shape of tea leaves, breaking down cell structure, and promoting the release of internal substances. As the core equipment for realizing this process, the structural design and performance of the rolling device directly affect the shaping effect and quality grade of the tea. Traditional rolling equipment mostly adopts a fixed structure, which completes the rolling action through the cooperation of the upper pressure mechanism and the bottom rotating plate. Over the long term, this type of equipment has gradually revealed problems such as inconvenience in operation and poor rolling uniformity, making it difficult to meet the modern tea processing requirements for efficient, clean, and stable quality production. In existing technologies, the kneading device barrel is mostly installed by bolting or welding. When cleaning or changing tea leaves, multiple connecting parts need to be disassembled, which is cumbersome and time-consuming. This structural design is particularly inconvenient in continuous production, affecting equipment utilization and production efficiency. In addition, the fixed barrel is prone to accumulating tea residue during long-term use, leading to unsanitary corners, increasing cleaning difficulty, and is not conducive to ensuring the hygiene and safety of tea processing. On the other hand, traditional kneading devices mostly use unidirectional pressure or rotational kneading methods, which can easily lead to tea leaves piling up, clumping, or uneven force during the kneading process. Especially when processing tea leaves with high moisture content or in large quantities, the equipment's ability to turn the tea leaves is insufficient, resulting in inadequate kneading and uneven leaf shape, which affects the appearance and quality consistency of the finished tea. Existing structures lack an effective tea leaf dispersion and turning mechanism, making it difficult to adapt to the processing requirements of different types and states of tea leaves, thus limiting the applicability of the equipment and the stability of the kneading effect. Therefore, a tea processing kneading device is proposed to solve the above problems. Utility Model Content

[0005] This utility model has the following beneficial effects: 1. In this utility model, the quick clamping and release of the barrel is achieved through the coordinated operation of the outer ring, short column, spring 2, handle, fixed rod, fixed block, clamping plate, movable column and inner ring in the clamping mechanism. The operator pulls the handle to compress spring 2, which drives the inner ring to slide along the inner wall of the outer ring. Then, the movable column pushes the clamping plate to rotate around the fixed rod, thus completing the clamping or releasing of the barrel. This structural design significantly simplifies the disassembly and assembly process, facilitates thorough cleaning and timely replacement of the barrel, effectively improves the practicality and operating efficiency of the equipment, and meets the needs of continuous production.

[0006] 2. In this utility model, through the linkage of the pressure cover, spring one, pressure plate, telescopic column, thin column, connecting plate two, and paddle in the pressure mechanism, the tea leaves are continuously turned and evenly pressurized during the kneading process. Spring one provides elastic pressure, causing the pressure plate to move up and down with the telescopic column, which drives the thin column and the paddle on it to gently turn the tea leaves. This combined structure effectively avoids the phenomenon of tea leaves clumping or uneven force during kneading, ensuring the integrity and uniformity of the tea leaves, thereby significantly improving the kneading quality and yield of the tea leaves.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] Example: A tea processing kneading device, as described in the following figure Figures 1 to 3 The assembly includes a support column 1, with a pressure mechanism 3 fixedly connected to its top. The pressure mechanism 3 applies controllable pressure to the tea leaves to optimize the kneading effect. A clamping mechanism 4 is also fixedly connected to the top of the support column 1, reliably securing the kneading mechanism 5 and allowing its movement. The kneading mechanism 5 is movably connected to the bottom of the clamping mechanism 4, supporting the tea leaves and performing the kneading operation. The pressure mechanism 3 includes a pressure cover 31, providing the structural foundation for the entire pressure assembly. Multiple springs 32 are fixedly connected to the bottom of the pressure cover 31, providing elastic pressure and cushioning impacts. A pressure plate 33 is fixedly connected to the bottom of each spring 32, distributing pressure evenly across the tea leaf surface. A telescopic column 34 is fixedly connected to the bottom of the pressure plate 33, transmitting pressure and allowing vertical displacement. The bottom of the telescopic column 34 is fixedly connected to a thin column 35, which is used to install the kneading action execution component. Multiple connecting plates 36 are fixedly connected to the outside of the thin column 35, which increases the installation points and range of motion of the kneading component. A paddle 37 is fixedly connected to one side of the connecting plate 36, which directly contacts the tea leaves and performs the kneading action. The top of the pressure cover 31 is threadedly connected to a threaded rod 38, which is used to adjust the initial pressure through threaded transmission. A folded rod 39 is threadedly connected to the outside of the threaded rod 38, which is used to change the transmission direction and transmit the adjustment force. A threaded rod 310 is threadedly connected to one side of the folded rod 39, which is used for secondary pressure fine adjustment. The bottom of the threaded rod 310 is rotatably connected to a power component 2, which is used to provide power for the entire pressurization and kneading action.

[0011] Specifically, the power component 2 drives the threaded rod 310 to rotate, and adjusts the height of the pressure cover 31 through the folded rod 39 and the threaded rod 38. Then, the pressure is transmitted to the telescopic column 34 and the paddle 37 through the spring 32 and the pressure plate 33. The paddle 37 contacts the tea leaves under pressure, and at the same time, the kneading mechanism 5 moves under the constraint of the clamping mechanism 4 to achieve uniform kneading of the tea leaves. The spring 32 provides buffering to ensure that the pressure is gentle and adjustable.

[0012] The power assembly 2 includes a rotating column 21, which serves as the core drive shaft to transmit the rotational motion of the power source to subsequent mechanisms. A fixed column 22 is rotatably connected to the top of the rotating column 21, which provides stable radial support and a rotation center for the rotating column 21, while also bearing the working load. A connecting plate 23 is rotatably connected to one side of the fixed column 22, which converts the rotational motion into planar oscillation and changes the direction of power transmission. A fixed plate 24 is rotatably connected to one side of the connecting plate 23, which provides a stable mounting base for the entire linkage mechanism, ensuring the stability and accuracy of power transmission.

[0013] Specifically, the power source drives the rotating column 21 to rotate, and the fixed column 22 provides support for it and defines the axis of rotation. The rotation of the rotating column 21 is converted into planar oscillation on the fixed plate 24 through the connecting plate 23, thereby reliably outputting power to the pressurizing mechanism 3 to achieve continuous pressure regulation.

[0014] Reference Figures 2 to 4 The clamping mechanism 4 includes an outer ring 41, which serves as the basic frame of the entire mechanism and provides installation support. A short column 42 is fixedly connected inside the outer ring 41, providing a fixed fulcrum for the elastic element. A spring 43 is fixedly connected to one side of the short column 42, providing the elastic preload required for clamping. A handle 44 is fixedly connected to one side of the spring 43, facilitating manual operation to control the clamping state. Multiple fixing rods 45 are fixedly connected to the top of the outer ring 41, supporting the rotating parts and determining their position. An externally rotating fixed block 46 is connected to the clamping plate 47, which serves as the rotation hub of the clamping plate 47. The clamping plate 47 is fixedly connected to one side of the fixed block 46, which directly clamps and fixes the kneading barrel 410. The externally rotating clamping plate 47 is connected to a movable column 48, which transmits the movement of the inner ring 49 to the clamping plate 47. The bottom of the movable column 48 is rotatably connected to the inner ring 49, which coordinates the synchronous movement of multiple clamping plates 47 by moving up and down. The barrel 410 is movably connected to one side of the clamping plate 47, which enables the clamping surface to self-adaptively fit with the barrel 410.

[0015] Specifically, the operator can pull the handle 44 to compress the second spring 43, causing the inner ring 49 to move down. The inner ring 49 drives multiple clamping plates 47 to rotate synchronously around the fixed block 46 through the movable column 48, thereby loosening or clamping the barrel 410. The second spring 43 provides continuous clamping force to ensure that the barrel 410 is stable and does not slip during the kneading process.

[0016] The kneading mechanism 5 includes a second support column 51, which provides stable vertical support for the kneading disc 52. The top of the second support column 51 is fixedly connected to the kneading disc 52, which carries the tea leaves and provides a kneading working surface. The top of the kneading disc 52 is fixedly connected to a rib 53, which simulates the hand kneading action to enhance the curling of the tea leaves and the breaking of cell walls. The inside of the kneading disc 52 is fixedly connected to a filter screen 54, which separates small broken leaves from tea juice during the kneading process to ensure the quality of the finished product.

[0017] Specifically, during the kneading process, the tea leaves are placed on the kneading disc 52, and the ribs 53 knead the tea leaves as the disc rotates. The filter screen 54 separates the tea juice.

[0018] The bottom of the rotating column 21 is fixedly connected to the top of the support column 1, and its function is to securely install the power assembly 2 onto the main frame. The outer wall of the pressure cover 31 contacts the inner wall of the barrel 410, and its function is to achieve a sealing fit between the pressure mechanism 3 and the kneading barrel to prevent tea leaves from spilling out. The outer wall of the outer ring 41 is fixedly connected to one side of the fixing plate 24, and its function is to install the clamping mechanism 4 as a whole onto the power base to ensure a stable force transmission path. The outer wall of the inner ring 49 is slidably connected to the inner wall of the outer ring 41, and its function is to ensure that the inner ring 49 can slide vertically along the inner wall of the outer ring 41 when under pressure, driving... The clamping plate 47 opens and closes synchronously. The outer wall of the handle 44 is slidably connected to the inner wall of the outer ring 41. Its function is to guide the linear movement of the handle 44 and accurately control the compression and release of the second spring 43. The bottom of the threaded rod 310 is rotatably connected to the top of the fixed plate 24. Its function is to reliably connect the pressure adjustment mechanism to the power base to achieve stable transmission. The inner part of the outer ring 41 has a groove, which provides precise installation and movement space for the spring. The outer wall of the second spring 43 contacts the inner wall of the groove. Its function is to use the groove to constrain the position of the spring, prevent deflection, and ensure accurate direction of elastic force.

[0019] Specifically, the clamping mechanism 4 is fixed to the fixed plate 24 by the outer ring 41. The operating handle 44 can drive the inner ring 49 to slide along the inner wall of the outer ring 41. The movable column 48 controls the clamping plate 47 to clamp or loosen the barrel 410. The pressure cover 31 contacts the inner wall of the barrel 410 to form a seal. The rotation of the threaded rod 310 can adjust the pressure. The whole system works together to achieve efficient kneading of tea leaves.

[0020] The implementation principle of this application embodiment is as follows: During operation, the operator puts the tea leaves to be processed into the barrel 410, and then pulls the handle 44 outward to compress the second spring 43, causing the inner ring 49 to slide downward along the inner wall of the outer ring 41. The inner ring 49 pushes the clamping plate 47 to rotate around the fixed rod 45 through the movable column 48, so that multiple clamping plates 47 simultaneously retract inward, firmly clamping the barrel 410 in the kneading position. After the clamping is completed, the power component 2 is started, and the rotating column 21 begins to rotate under the drive of external power. The rotational motion is converted into the up-and-down reciprocating motion of the fixed plate 24 through the fixed column 22 and the connecting plate 23.

[0021] The fixed plate 24 drives the threaded rod 310 connected to it to move, and then transmits the movement to the pressure cover 31 through the folded rod 39 and the threaded rod 38, driving it to press down as a whole. When the pressure cover 31 is pressed down, the spring 32 is compressed, providing elastic pressure to the pressure plate 33. The pressure plate 33 drives the thin column 35 and multiple connecting plates 36 and the paddle 37 fixed on it to move downward together through the telescopic column 34 at the bottom, penetrating deep into the tea leaves. With the rotation of the kneading disc 52 and the cooperation of the ribs 53, the paddle 37 fully turns and kneads the tea leaves, so that the tea leaves are evenly stressed. The tea juice seeps out effectively through the filter screen 54 in the kneading disc 52. After the kneading process is completed, the operator pulls the handle 44 in the opposite direction to release the clamp 47 from the barrel 410, so that the barrel 410 can be taken out for cleaning and prepared for the next processing.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
