Abstract
Description
Technical Field
[0001] This invention relates to a kneading machine, and more specifically to an intelligent tea kneading machine, belonging to the field of tea processing technology. Background Technology
[0002] Rolling is a gentle yet firm "shaping" process in the life of tea leaves. With the uniform rotation and pressure of the machine, the leaves begin to curl and tumble rhythmically. During this process, profound changes occur within the leaves: the cell walls are moderately broken down, and the tea juice and aromatic substances contained within are slowly squeezed out, quietly adhering to the leaf surface, laying the foundation for the rich flavor of the future tea infusion. At the same time, the leaf shape gradually changes from an extended form to a tightly rolled strip, resembling a snail, a needle, or a bead, initially shaping it into the familiar commercial form we know. Rolling gives tea leaves its shape and further enhances their inner charm, serving as a bridge connecting the fresh, herbaceous aroma of the fresh leaves with the full-bodied soul of the finished tea. This is not only a crucial step in the tea-making process but also an art of "transformation" for the tea leaves.
[0003] However, in current tea rolling processes, the intensity and speed of rolling largely depend on the tea master's experience, often leading to inconsistent tea quality and wasted labor. While automated rolling equipment exists that operates overnight, it typically only achieves continuous production; crucial aspects such as the application of rolling force and the judgment of rolling intensity still rely on manual intervention. Furthermore, after rolling and unloading, residual tea leaves remain on the rolling pan, mostly requiring manual cleaning after power is cut off. Even automated rolling machines currently rely on manual cleaning, which cannot be completed in one pass and requires multiple adjustments to the angle for thorough cleaning. These cleaning methods are cumbersome and risky, failing to meet the required standards. Summary of the Invention

Detailed Implementation
[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] See Figures 1 to 10 A smart tea kneading machine includes a support leg 1, a kneading disc 3, a first motor 4, a reduction gearbox 5, a control box 6, a kneading drum 20, a second motor 25, a third motor 26, an electric push rod 30, a guide plate 31, a second electric push rod 35, a base plate 36, a fourth motor 39, a swing arm 40, a brake 46, and a reducer 47. The kneading drum 20 is positioned above the kneading disc 3, and has no lids at either end. The kneading drum 20 can rotate relative to the kneading disc 3. A suspension 11 is fitted onto the kneading drum 20, and multiple supports are arranged circumferentially on the suspension 11. One of these supports is connected to shaft 7 of the reduction gearbox 5 via a drive arm 10, and the remaining supports are connected to shaft 3 16 at the top of the support leg 1 via follower arms 15. The kneading disc 3 has a discharge port at its bottom. Below this discharge port are a left discharge port disc 21 and a right discharge port disc 22, which cover the discharge port. Both the left and right discharge port discs 21 and 22 are connected to a rotating rod 23, which is connected to a shaft 24. The shaft 24 on the left discharge port disc 21 side is connected to a motor 25, and the shaft 24 on the right discharge port disc 22 side is connected to a motor 3 26. A suspension cover 41 is provided above the kneading drum 20. The radius of the suspension cover 41 is smaller than the radius of the kneading drum 20, allowing it to be fully inserted into the kneading drum 20 during kneading. A ball-head rod 43 is provided at the top of the suspension cover 41, connected to a swing rod 40. A spring 42 is fitted over the ball-head rod 43, with one end of the spring 42 fixed to the suspension cover 41. The swing arm 40 is connected to the output shaft of the reducer 47. The motor 49 is connected to the brake 46, and the brake 46 is connected to the reducer 47. The reducer 47 is fixed on the base plate 36. The driving end of the electric push rod 2 35 is connected to the base plate 36, and the base plate 36 is connected to the guide post 37. The fixed end of the electric push rod 2 35 and the other end of the guide post 37 are fixed to the suspension 11. The motor 1 4 is connected to the reduction gearbox 5. The motor 1 4, motor 2 25, motor 3 26, electric push rod 2 35, and motor 4 39 are all connected to the control box 5.
[0029] See Figures 1 to 10It also includes an electric push rod 30 and a guide plate 31, with an electric push rod 35 passing through the guide plate 31. Columns 33 are installed on both sides of the guide plate 31, and cleaning plates 34 are mounted on the column rods 33. A brush is mounted at the lower end of each cleaning plate 34. The cleaning plates 34 are distributed in a fan shape along the outer circumference of the kneading drum 20, with a radius slightly larger than the outer circumference of the kneading drum 20. The driving end of the electric push rod 30 is connected to the guide plate 31, and the fixed end of the electric push rod 30 is fixed to the suspension 11. The electric push rod 30 is connected to the control box 5. After the kneading process is completed, during the unloading process, when the discharge port at the bottom of the kneading disc 3 opens, the kneading drum 20 slowly rotates, and the tea leaves fall down. However, there will be residual tea leaves on the kneading disc 3. By setting up a cleaning plate 34, when the left feed plate 25 and the right feed plate 26 are opened, the electric push rod 30 is activated, driving the cleaning plate 34 to move down. As the kneading drum 20 rotates, the residual tea leaves on the kneading disc 3 and the left feed plate 21 can be cleaned. The specific process is as follows: when the left feed plate 21 is opened, the cleaning plate 34 moves down. The cleaning plate 34 rotates with the kneading drum 20, and the residual tea leaves on the kneading disc 3 are cleaned. When the left feed plate 21 is closed, the right feed plate 22 is opened, and cleaning continues until the cleaning is completed.
[0030] See Figures 1 to 10 Specifically, the kneading disc 3 is provided with ribs 19, which are arranged in a counterclockwise spiral from the outside to the inside of the kneading disc 3.
[0031] See Figures 1 to 10 Specifically, the top of the ball head 43 is provided with a locking cover 44.
[0032] See Figures 1 to 10 Specifically, the spring 42 is fixed to the suspension cover 41 by the flange seat 45.
[0033] See Figures 1 to 10 Specifically, the gearbox 5 is fixed on the support 2.
[0034] See Figures 1 to 10 Specifically, one end of the guide post 37 passes through the substrate 36, and a guide sleeve 38 is provided between the substrate 36 and the guide post 37.
[0035] See Figures 1 to 10Specifically, the drive arm 10 is sleeved on shaft 7 of the reduction gearbox 5. The drive arm 10 is connected to shaft 12, and bearing 13 is sleeved on shaft 12. A bracket on the suspension 11 is sleeved on shaft 12. One end of the follower arm 15 is connected to shaft 16 at the top of the support leg 1. Bearing 17 is provided between shaft 16 and support leg 1. A bushing 18 is provided outside bearing 17. The other end of the follower arm 15 is fixedly connected to shaft 12. The remaining brackets on the suspension 11 are sleeved on the shaft 12 corresponding to the follower arm 15. Bearing 13 is provided between the bracket and shaft 12.
[0036] See Figures 1 to 10This device can operate as a standalone unit or in a production line. When the device is in operation, it is first started, and parameters are set in the control box 6. These parameters include the number of kneading periods; each kneading period includes the displacement of the lowered cover 41, the speed of motor 4, and the kneading duration. The displacement of the lowered cover 41 is set based on a comprehensive consideration of the tea composition, production period, and climate characteristics. The displacement of the lowered cover 41 can be set individually for each kneading period. The force applied to the tea is often applied in a "light-heavy-light" manner. Then, the production mode is set. In standalone production mode, click "Load Tea" on the control box 6 screen; in production line mode, the host computer will issue a "Load Tea" signal. After the production mode is determined, motors 25 and 36 start, respectively closing the left and right feed inlet discs 21 and 22 to seal the discharge port. Next, material feeding begins. At this time, electric push rod 35 starts, moving the substrate 36 and its components to the highest position. Motor 39 starts, rotating the swing arm 40, which removes the cover 41. Material is then fed into the kneading drum 20 manually or via a conveyor. Once feeding is complete, click the "Filling Complete" button on the control box 6 screen. If it is in line production mode, the host computer will issue a "Filling Complete" signal. Motor 39 starts, rotating the swing arm 40, which moves the cover 41 into the kneading drum 20. Electric push rod 35 starts, moving the substrate 36 and its components to the preset position. Motor 4 starts and operates according to the set parameters. Motor 4 drives the shaft 7 of the reduction gearbox 5 to rotate, and shaft 7 drives the drive arm 10, thereby causing the barrel frame 9 to rotate eccentrically relative to the center of the kneading disc 4. The tea leaves interact with the ribs 9 in the space composed of the kneading disc 3, the suspended cover 41, and the kneading barrel 20, and gradually form strips. The speed of motor 4 is determined by the process parameters. The speed of motor 4 is usually set to "slow-fast-slow". In the early stage of kneading, slow kneading is often used, which is implemented by issuing control commands through the control box 6. During the operation of motor 4, the electric push rod 35 moves up and down according to the set parameters based on the kneading period to realize the force control process. Finally, upon completion of the program, control box 6 sends a signal, motor 25 drives the left feed inlet plate 25 to open, electric push rod 30 drives guide plate 31 and its components to move downwards, cleaning plate 34 contacts kneading disc 3, motor 4 starts and rotates slowly (5-15) revolutions, tea leaves are conveyed out of kneading drum 20, motor 25 drives the left feed inlet plate 25 to close; motor 3 starts and drives the right feed inlet plate 26 to open, motor 4 starts and rotates slowly several revolutions, electric push rod 30 drives guide plate 31 and its components to move upwards to the initial position, and the kneading process is completed. This process completely realizes production automation and unmanned operation, liberating labor, improving tea production efficiency, and enhancing tea quality; it also achieves automatic cleaning function, so that residual tea leaves on kneading disc 3 are automatically cleaned.
[0037] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such structures should be considered within the protection scope of the present invention.
