Description

Technical Field

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

[0002] Tea rolling is a crucial step in tea processing. Rolling breaks down tea leaves, extracting tea juice to facilitate brewing and increase the concentration of the tea infusion. Traditional continuous rolling machines mainly consist of a rolling disc, a rolling drum, a pressure device, and a transmission mechanism. The surface of the rolling disc is usually decorated with spiral or radially distributed rolling ridges to enhance the rolling effect on the tea leaves.

[0003] However, existing continuous kneading machines have the following shortcomings: During the kneading process, tea fragments, tea juice, and fibers easily adhere to the surface of the kneading ridges and grooves, which not only affects the kneading effect but may also contaminate the tea and reduce its quality. Furthermore, cleaning mainly relies on manual periodic disassembly and washing of the kneading discs, which is cumbersome, time-consuming, and labor-intensive, and real-time cleaning is difficult to achieve, thus impacting production efficiency. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a continuous tea rolling device, the specific technical solution of which is as follows: A continuous tea kneading device includes a support column, a kneading disc mounted on the support column, a kneading barrel located above the kneading disc, and a transmission mechanism for driving the kneading barrel to swing in a planar manner. The surface of the kneading disc is provided with kneading protrusions distributed in a spiral pattern. A cleaning assembly is detachably connected to the bottom of the kneading barrel. The cleaning assembly includes a top plate, a middle plate, and a bottom strip block arranged sequentially from top to bottom. The middle plate and the bottom strip block are connected by multiple elastic elements. The bottom of the bottom strip block has a circular cleaning brush. A through-hole structure communicating with the inner cavity of the bottom strip block is provided between the bottom strip block and the cleaning brush. A dust suction part for generating negative pressure in the inner cavity of the bottom strip block is installed on the top plate. The kneading barrel has a pressurizing device as used in the prior art.

[0005] As a further improvement to the above technical solution, the outer side of the kneading drum is fitted with a bottom annular block, and the support column is provided in three sets. The top of each set of support columns is rotatably connected to a rotating shaft, and the top of the rotating shaft is connected to a first movable block. The end of the first movable block away from the rotating shaft is rotatably connected to a second movable block through a pin, and the end of the second movable block away from the pin is fixedly connected to the bottom annular block.

[0006] As a further improvement to the above technical solution, the transmission mechanism includes a drive motor installed inside one of the support columns, and the output shaft of the drive motor is fixedly connected to an adjacent rotating shaft.

[0007] As a further improvement to the above technical solution, a top annular block is fixedly connected to the outer side of the kneading drum and above the bottom annular block. The bottom annular block and the top annular block are coaxially arranged. Several hydraulic cylinders are installed on the bottom annular block, and the output rods of the hydraulic cylinders are fixedly connected to the top annular block through L-shaped connecting rods.

[0008] As a further improvement to the above technical solution, the top of the bottom annular block and / or the bottom of the top annular block have annular rubber pads.

[0009] As a further improvement to the above technical solution, the top of the top plate has several fixing blocks, the fixing blocks are provided with a first threaded hole, and the outer side of the kneading drum is provided with a second threaded hole. When the cleaning component is coaxially connected to the bottom of the kneading drum, the fixing bolts are rotated and inserted into the first threaded hole and the second threaded hole to fix the cleaning component and the kneading drum.

[0010] As a further improvement to the above technical solution, the dust collection unit includes a miniature vacuum cleaner installed at the bottom of the top plate. The suction end of the miniature vacuum cleaner is connected to the inside of the bottom strip block through a hose. The through hole structure includes several through holes one provided at the bottom of the bottom strip block and several through holes two provided on the cleaning brush.

[0011] As a further improvement to the above technical solution, an electric telescopic rod is installed at the bottom of the top plate, and the output rod of the electric telescopic rod is fixedly connected to the intermediate plate.

[0012] As a further improvement to the above technical solution, the elastic element is composed of a spring and a damper.

[0013] The beneficial effects of this utility model are: 1. The cleaning component is designed to clean the kneading protrusions on the kneading disc during the kneading drum's oscillation. The cleaning brush removes tea fragments, tea juice, and fibers adhering to the surface and grooves of the kneading protrusions. Simultaneously, the suction unit generates negative pressure through its perforated structure to promptly suck away the cleaned impurities, preventing them from falling back onto the kneading disc. This ensures effective cleaning, thereby guaranteeing the kneading effect and the quality of the tea.

[0014] 2. The elastic element design allows the bottom strip and cleaning brush to better conform to the surface of the kneading disc and the kneading protrusions. Even when the surface of the kneading disc is uneven or the height of the kneading protrusions varies, it can still maintain good cleaning contact, improving the comprehensiveness and reliability of cleaning.

[0015] 3. The cleaning component is detachably connected to the kneading drum, making it easy to disassemble when cleaning is not needed without affecting the normal kneading operation of the kneading device. It also facilitates the maintenance and replacement of the cleaning component.

[0016] 4. The three sets of support columns and the structure connected to the bottom ring block through the rotating shaft, the first movable block, the pin, the second movable block, can stably support the kneading drum and, in conjunction with the transmission mechanism, realize the planar swing of the kneading drum, ensuring the stable operation of the kneading work.

[0017] 5. The hydraulic cylinder connects the top annular block and the bottom annular block via an L-shaped connecting rod, which can realize the lifting and lowering of the kneading drum. This makes it easy to adjust the distance between the kneading drum and the kneading disc to adapt to different kneading needs. It also makes it convenient to raise the kneading drum for cleaning or other operations when needed.

[0018] 6. The annular rubber gasket reduces the collision and friction between the bottom and top annular blocks when the hydraulic cylinder drives the kneading drum to rise and fall, thus providing cushioning and protection and extending the service life of the device.

[0019] 7. The electric telescopic rod can adjust the position of the middle plate, bottom strip, and cleaning brush to adapt to different cleaning needs and kneading conditions, improving the flexibility of the cleaning components.

[0020] 8. The elastic element consists of a spring and a damper. It is both elastic, which can achieve buffering and fitting, and the damper can reduce vibration and ensure the stability of the cleaning component. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example Please refer to Figures 1-2A continuous tea kneading device includes a support column 2, a kneading disc 1 set on the support column 2, a kneading barrel 3 located above the kneading disc 1, and a transmission mechanism for driving the kneading barrel 3 to swing in a plane. The surface of the kneading disc 1 is provided with kneading protrusions 11 distributed in a spiral shape, and the kneading barrel 3 has a pressure device as in the prior art.

[0025] The bottom of the kneading drum 3 is detachably connected to a cleaning assembly 6, which includes a top plate 60, a middle plate 61, and a bottom strip 64 arranged sequentially from top to bottom. The top of the top plate 60 has several fixing blocks 4, each with a first threaded hole. The outer side of the kneading drum 3 has a second threaded hole. When the cleaning assembly 6 is coaxially connected to the bottom of the kneading drum 3, the fixing bolts 41 are rotated and inserted into the first and second threaded holes to fix the cleaning assembly 6 and the kneading drum 3. This connection method facilitates disassembly and installation.

[0026] An electric telescopic rod 62 is installed at the bottom of the top plate 60. The output rod of the electric telescopic rod 62 is fixedly connected to the intermediate plate 61. The extension and retraction of the electric telescopic rod 62 can drive the intermediate plate 61 to move up and down. The intermediate plate 61 and the bottom strip 64 are connected by multiple elastic elements 66. The elastic elements 66 are composed of springs and dampers. The springs provide elastic support, and the dampers can reduce vibration, making the movement of the bottom strip 64 smoother.

[0027] The bottom of the bottom strip 64 has a circular cleaning brush 65, which can contact the surface of the kneading disc 1 and the kneading protrusions 11 to remove impurities. A through-hole structure communicating with the inner cavity of the bottom strip 64 is provided between the bottom strip 64 and the cleaning brush 65. The through-hole structure includes several through holes 641 at the bottom of the bottom strip 64 and several through holes 651 on the cleaning brush 65. Impurities can enter the inner cavity of the bottom strip 64 through these through holes.

[0028] The top plate 60 is equipped with a vacuuming unit for generating negative pressure in the inner cavity of the bottom strip 64. The vacuuming unit includes a mini vacuum cleaner 63 installed at the bottom of the top plate 60. The suction end of the mini vacuum cleaner 63 is connected to the inside of the bottom strip 64 through a hose 631. When the mini vacuum cleaner 63 is working, it generates negative pressure through the hose 631, the inner cavity of the bottom strip 64 and the through hole structure, sucking in and collecting the cleaned impurities.

[0029] The outer side of the kneading drum 3 is fitted with a bottom annular block 31. Three sets of support columns 2 are provided, each with a rotating shaft 21 rotatably connected to its top. A first movable block 22 is connected to the top of the rotating shaft 21. A second movable block 24 is rotatably connected to the end of the first movable block 22 away from the rotating shaft 21 via a pin 23. The end of the second movable block 24 away from the pin 23 is fixedly connected to the bottom annular block 31. This connection structure provides support and space for the kneading drum 3 to swing.

[0030] The transmission mechanism includes a drive motor installed inside one of the support columns 2, and the output shaft of the drive motor is fixedly connected to the adjacent rotating shaft 21. When the drive motor is working, it drives the rotating shaft 21 to rotate, which in turn drives the bottom annular block 31 and the kneading drum 3 to perform planar oscillation through the first movable block 22, the pin 23 and the second movable block 24, thereby realizing the kneading action.

[0031] A top annular block 32 is fixedly connected to the outer side of the kneading drum 3, above the bottom annular block 31. The bottom annular block 31 and the top annular block 32 are coaxially arranged. Several hydraulic cylinders 5 are installed on the bottom annular block 31. The output rods of the hydraulic cylinders 5 are fixedly connected to the top annular block 32 through L-shaped connecting rods 51. When the hydraulic cylinders 5 extend or retract, they drive the top annular block 32 and the kneading drum 3 to rise and fall through the L-shaped connecting rods 51, adjusting the distance between the kneading drum 3 and the kneading disc 1.

[0032] The bottom annular block 31 has annular rubber pads at the top and the top annular block 32 at the bottom. During the lifting and lowering of the kneading drum 3, the collision and friction between the bottom annular block 31 and the top annular block 32 can be reduced, thus playing a buffering and protective role.

[0033] Working principle: When kneading tea leaves, the tea leaves are placed between the kneading disc 1 and the kneading barrel 3. The pressure device applies pressure to the kneading barrel 3, drives the motor to work, and drives the rotating shaft 21 to rotate. Through the first movable block 22, the pin 23 and the second movable block 24, the bottom ring block 31 and the kneading barrel 3 swing in a plane, which, together with the kneading protrusions 11 on the kneading disc 1, kneads the tea leaves.

[0034] When cleaning is required, adjust the height of the kneading drum 3 upwards, then install the cleaning assembly between the kneading drum 3 and the kneading disc 1. Activate the electric telescopic rod 62 and adjust the positions of the middle plate 61, bottom strip block 64, and cleaning brush 65 so that the cleaning brush 65 contacts the surface of the kneading disc 1 and the kneading protrusions 11. While the kneading drum 3 is swinging, activate the mini vacuum cleaner 63. The cleaning brush 65 removes impurities from the surface and grooves of the kneading protrusions 11. The impurities enter the inner cavity of the bottom strip block 64 through through hole two 651 and through hole one 641, and are then sucked away by the mini vacuum cleaner 63 through the hose 631.

[0035] The elastic element 66 ensures that the cleaning brush 65 always maintains good contact with the kneading disc 1 and the kneading protrusions 11, thereby improving the cleaning effect.

[0036] To adjust the height of the kneading drum 3, simply extend or retract the hydraulic cylinder 5. When cleaning is not required, unscrew the fixing bolt 41 and remove the cleaning assembly 6 from the bottom of the kneading drum 3.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
