Description

Technical Field

[0001] This utility model relates to the field of tea kneading, specifically an automatic tea-sweeping and kneading device. Background Technology

[0002] In traditional tea-making, rolling is a crucial step in shaping the tea leaves and releasing their internal substances. This process breaks down the cell walls of the tea leaves with external force, causing the tea juice to seep out and adhere evenly to the leaf surface. This enhances the richness and aroma of the tea soup and lays the foundation for subsequent drying and shaping. Mechanical rolling must balance the degree of cell damage with fiber integrity to avoid excessive pressure that could lead to juice loss or leaf breakage.

[0003] Currently, the mainstream tea rolling machines on the market can be divided into three categories based on their working principle: drum rolling machines, which use rotating drums to repeatedly squeeze tea leaves between the drum wall and the ribs; trough rolling machines, which use an arc-shaped trough combined with an adjustable pressure plate, causing the tea leaves to form a spiral motion trajectory within the trough; and spiral rolling machines, which use a spiral propeller to achieve a combined axial and radial motion of the tea leaves.

[0004] For example, the Chinese authorized patent CN 213153789 U (A Chrysanthemum Tea Kneading Device) includes a kneading machine. A tripod is movably connected to the top of the kneading machine via a shaft. A cylinder and a support rod are fixedly installed on one side of the top of the tripod. A sleeve is movably fitted onto the outer side of the support rod. A disc and a cross arm are fixedly fitted onto the outer side of the sleeve. A movable groove is formed at the bottom of the disc. In this chrysanthemum tea kneading device, the upward movement of the cylinder moves the disc, connecting rod, and tea-pressing lid upwards, facilitating the removal of the tea-pressing lid from the inner cavity of the kneading drum. As the cylinder moves, it moves the support rod to contact the external threads on the support rod, allowing the disc to rotate along the outer side of the support rod, facilitating the rotation of the tea-pressing lid to one side of the kneading drum and opening the drum. The downward movement of the cylinder presses the chrysanthemum flowers inside the kneading drum, improving the efficiency of the device.

[0005] The aforementioned existing technology has the function of kneading, but the tea leaves form a spiral motion trajectory in the trough. Under the pressure of the tea pressing plate and the spiral motion, some debris will be generated. This debris cannot be discharged in time and will be transported out along with the kneaded tea leaves, affecting the quality of the finished product. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1-6 One embodiment of this utility model is an automatic tea sweeping and kneading device, which mainly includes a workbench 1 and a tea sweeping and kneading unit 38.

[0027] The workbench 1 consists of a support frame 2 and an upper platform 3, with the upper platform 3 installed within the support frame 2. Multiple kneading discs 4 are arrayed on the upper surface of the upper platform 3, and kneading ribs 6 are fixed in a circular array on the upper surface of each kneading disc 4. A kneading cavity 5 is formed inside each kneading disc 4. When tea leaves enter, during the kneading process, the tea leaves follow the kneading ribs 6 in a spiral motion, thus receiving thorough kneading action. This breaks down the tea cells, releases tea juice, and creates the unique aroma and flavor of the tea.

[0028] The kneading disc 4 has a feeding port 7 on its end face for the tea leaves to fall. A lower impurity removal assembly 8 is located at the lower end of the kneading disc 4 along the outside of the feeding port 7. The lower impurity removal assembly 8 consists of an upper feed pipe 9, a distribution pipe 10, a convergent impurity removal pipe 11, and a discharge pipe 12. These components are integrally formed from top to bottom, with the distribution pipe 10 having a larger diameter than the upper feed pipe 9. A fixing mesh 13 is installed within the stepped inner wall of the upper feed pipe 9 and the convergent impurity removal pipe 11. The inner walls of the upper feed pipe 9, the fixing mesh 13, and the discharge pipe 12 have a smooth transition, ensuring the tea leaves can fall smoothly. An impurity cavity 14 is formed along the outside of the fixing mesh 13 inside the lower impurity removal assembly 8 to collect debris from the tea leaves; a tea leaf falling cavity 15 is formed along the inside of the fixing mesh 13 inside the lower impurity removal assembly 8 for the tea leaves to fall. A branch air inlet pipe 16 is installed at the rear end of the distribution pipe 10. Multiple branch air inlet pipes 16 are connected to a main air inlet pipe 17 at their rear ends for supplying air into the tea leaf falling chamber 15. A branch exhaust pipe 18 is installed at the front end of the converging exhaust pipe 11. The branch exhaust pipe 18 is inclined downwards, and multiple branch exhaust pipes 18 are connected to a main exhaust pipe 19 at their front ends. Debris, under the influence of the airflow and the inclined branch exhaust pipes 18, flows along the branch exhaust pipes 18 into the main exhaust pipe 19. An external structure then draws the debris out of the main exhaust pipe 19. This exhaust structure effectively removes debris from the tea leaves, greatly improving the quality and purity of the tea.

[0029] Tea leaves fall through the feed port 7 into the tea leaf dropping chamber 15 of the lower waste removal component 8, and are then discharged through the discharge pipe 12. There is a tea leaf conveying unit at the lower end of the support frame 2. After the tea leaves are discharged, they reach the upper end of the tea leaf conveying unit and are conveyed out.

[0030] A first drive motor 27 is mounted on the rear end of the lower end of the upper platform 3 via a motor bracket. An intermediate connecting rod 20 is arranged along the outside of the kneading disc 4 at the upper end of the upper platform 3. Three intermediate connecting rods 20 are arranged at equal angles to the connection end of the upper platform 3, with each group of three intermediate connecting rods 20 facing the same direction. One end of the intermediate connecting rod 20 is rotatably connected to the upper platform 3 via a shaft, and the upper end of the other end of the intermediate connecting rod 20 is rotatably connected to a connecting arm 21 via a shaft. A central fixing ring 22 is fixed between the three connecting arms 21. A kneading cylinder 23 is installed inside the central fixing ring 22, with its lower end extending into the kneading cavity 5. A tea-receiving sweeping hopper 37 is installed at the rear end of the upper end of the kneading cylinder 23. The first drive motor 27 drives one of the intermediate connecting rods 20 to rotate, pulling the connecting arm 21 and the central fixing ring 22 to rotate. The other intermediate connecting rods 20 move in coordination, thereby causing the tea-sweeping and kneading unit 38 to rotate within the kneading cavity 5, achieving the kneading of the tea leaves. This structure allows the tea leaves to be subjected to even force during the kneading process, resulting in a more ideal kneading effect.

[0031] Side fixing ears 24 are formed on both sides of the intermediate fixing ring 22. Upper fixing posts 25 are provided at the upper ends of the side fixing ears 24. An upper support beam 26 is installed at the upper ends of the two upper fixing posts 25. An intermediate fixing plate 28 is formed in the middle of the upper support beam 26. A support plate 29 is fixed to the front end of the intermediate fixing plate 28. A second drive motor 30 is installed at the upper end of the support plate 29. A first bevel gear 31 is installed at the output shaft end of the second drive motor 30. A second bevel gear disk 32 is rotatably connected to the upper end of the intermediate fixing plate 28. A central rotating threaded rod 33 is threadedly connected inside the second bevel gear disk 32. The upper end of the central rotating threaded rod 33 extends upwards. A hole is provided inside the intermediate fixing plate 28 for the central rotating threaded rod 33 to pass through. The lower end of the central rotating threaded rod 33 is equipped with a lower fixed crossbar 34, and the lower end of the lower fixed crossbar 34 is fixed with a tea pressing tray 36. The maximum diameter of the tea pressing tray 36 matches the inner diameter of the kneading cylinder 23. Limiting uprights 35 are fixed on both sides of the upper end of the lower fixed crossbar 34. The upper end of the limiting uprights 35 extends upward through the upper support crossbeam 26.

[0032] The upper part of the support frame 2 is equipped with a tea conveying mechanism and a feeding hopper. The tea conveying mechanism transports tea leaves to each feeding hopper, and the feeding hoppers guide the tea leaves to fall to the upper part of the receiving tea sweeping hopper 37. The second drive motor 30 drives the first bevel gear 31 to rotate. Through the meshing connection between the first bevel gear 31 and the second bevel gear disk 32, the second bevel gear disk 32 is driven to rotate. The intermediate rotating threaded rod 33, which is threaded to the second bevel gear disk 32, moves upward, driving the lower fixed crossbar 34 and the tea pressing plate 36 to move upward. The upper part of the kneading cylinder 23 is exposed, and the tea leaves enter the kneading cylinder 23 through the feeding hopper and the receiving tea sweeping hopper 37. The second drive motor 30 drives the first bevel gear 31 to rotate in the opposite direction, and the tea pressing plate 36 moves downward to apply a certain pressure to the tea leaves, realizing the automated control of feeding and pressing, which is easy to operate and improves production efficiency.

[0033] The work process is as follows:

[0034] The tea conveying mechanism at the upper end of the support frame 2 conveys the tea to each feeding hopper, and the feeding hopper guides the tea to fall to the upper end of the receiving sweeping tea hopper 37.

[0035] The second drive motor 30 drives the first bevel gear 31 to rotate, which in turn drives the second bevel gear disk 32 to rotate. The central rotating threaded rod 33 moves upward, which in turn drives the lower fixed crossbar 34 and the tea pressing tray 36 to move upward. The upper end of the kneading cylinder 23 is exposed, and the tea leaves enter the kneading cylinder 23.

[0036] The second drive motor 30 drives the first bevel gear 31 to rotate in the opposite direction, and the tea pressing tray 36 moves downward to apply a certain pressure to the tea leaves.

[0037] The first drive motor 27 drives one of the intermediate connecting rods 20 to rotate, pulling the connecting arm 21 and the intermediate fixed ring 22 to rotate. The other intermediate connecting rods 20 move in coordination. The tea sweeping and kneading unit 38 rotates within the kneading chamber 5. The tea leaves are kneaded and shaped along the spiral motion trajectory formed by the kneading ribs 6.

[0038] Tea leaves fall through the feed inlet 7 into the tea leaf falling chamber 15 of the lower impurity discharge assembly 8. The air inlet main pipe 17 is ventilated and sent into the lower impurity discharge assembly 8 through the air inlet branch pipe 16. The airflow acts on the tea leaves in the tea leaf falling chamber 15 through the holes on the fixed mesh 13. Some debris will pass through the holes on the fixed mesh 13 under the action of the airflow and reach the impurity chamber 14. Under the action of the airflow and the inclined impurity discharge branch pipe 18, it enters the impurity discharge main pipe 19 along the impurity discharge branch pipe 18. The external structure attracts the debris in the impurity discharge main pipe 19 to be discharged.

[0039] The kneaded tea leaves are discharged through the discharge pipe 12 and reach the upper end of the tea leaf conveying unit inside the lower part of the support frame 2, where they are conveyed out.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
