Description

Technical Field

[0001] This utility model relates to the field of tea rolling technology, specifically a tea rolling machine with controllable rolling pressure. Background Technology

[0002] Rolling is a key step in tea processing. It shapes the tea leaves, making them curl into strips and reduce their volume, which facilitates subsequent processing such as roasting. Pressure adjustment is required during rolling to prevent quality degradation caused by improper pressure, reduce waste and substandard products, and minimize raw material waste.

[0003] For example, a tea rolling machine with authorization announcement number "CN207185833U" features a parallel disc and a pressure plate. A drive assembly drives the pressure plate to rotate relative to the disc, ensuring that the tea leaves are subjected to the same extrusion pressure from both the disc and the pressure plate. Rolling is achieved through raised strips, resulting in high uniformity. However, the structure for adjusting the disc height in this tea rolling machine is limited to a narrow range based on the fixed position of the through-hole. Therefore, the fixed through-hole position cannot provide adequate adjustment for tea piles of different thicknesses. Furthermore, each adjustment requires turning a screw to move the connecting rod within the fixed through-hole position, making the operation cumbersome and time-consuming. Additionally, the pressure plate design of this tea rolling machine is relatively fixed, relying mainly on the circular wavy raised strips, ribs, and disc in conjunction with the rolling process, which cannot shape the tea leaves into different shapes. Utility Model Content

[0004] The purpose of this invention is to solve the problems of fixed through-hole positions in the current tea kneading machine, which cannot provide appropriate pressure adjustment, and the need to tighten screws to move the connecting rod within the fixed through-hole for each adjustment, which is cumbersome and time-consuming. The design of the pressure plate of the tea kneading machine is relatively fixed, mainly relying on the cooperation of circular wave-shaped convex strips, ribs and discs for kneading, which cannot shape the tea into different shapes. Therefore, this invention proposes a tea kneading machine with controllable kneading pressure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a tea kneading machine with controllable kneading pressure, including a base and a curved plate. The curved plate is fixedly connected to the rear end of the base, and a horizontal block is fixedly connected to the upper front end of the curved plate. The inner wall of the horizontal block is rotatably connected to a first housing through a bearing. The interior of the first housing is provided with a tea plasticity adjustment structure, and a disc is installed on the upper end of the base.

[0007] Preferably, the tea plasticity adjustment structure includes a first servo motor, the outer wall of which is fixedly connected to a first housing, a threaded rod fixedly connected to the output shaft of the first servo motor, both ends of which are rotatably connected to the first housing via bearings, the threaded rod being threadedly connected to a threaded block, a first block fixedly connected to the upper end of the threaded block, the inner wall of which is slidably connected to a first slide rod, both ends of which are fixedly connected to the first housing, and a second block fixedly connected to the lower end of the threaded block, the outer wall of which is slidably connected to the first housing.

[0008] Preferably, the lower end of the second block is fixedly connected to a second housing, and the interior of the second housing is provided with a kneading pressure adjustment structure.

[0009] Preferably, the kneading pressure adjustment structure includes a third servo motor, the outer wall of which is fixedly connected to the second housing. A worm gear is fixedly connected to the output shaft of the third servo motor, and both ends of the worm gear are rotatably connected to the second housing via bearings. The worm gear meshes with a worm wheel, and both ends of the worm wheel's rotating shaft are rotatably connected to the second housing via bearings. A connecting rod is fixedly connected to the outer wall of the worm wheel's rotating shaft, and a cylinder is fixedly connected to the end of the connecting rod. The outer wall of the cylinder is slidably connected to a groove frame, and the inner walls on both sides of the groove frame are slidably connected to a second sliding rod. The outer wall of the groove frame is slidably connected to the second housing.

[0010] Preferably, a pressure plate is fixedly connected to the lower end of the groove frame, and both ends of the second slide rod are fixedly connected to the second housing.

[0011] Preferably, a second servo motor is fixedly connected to the outer wall of the bent plate, and the output shaft of the second servo motor is fixedly connected to the first housing.

[0012] This utility model proposes a tea kneading machine with controllable kneading pressure. Its advantages lie in the following: through the cooperation of the kneading pressure adjustment structure and the second housing, the output shaft of the third servo motor rotates, driving the worm gear to rotate. The worm gear then drives the worm wheel to rotate. Furthermore, the worm wheel and worm gear have a self-locking characteristic, preventing displacement of the pressure plate during operation. The rotation of the worm wheel drives the connecting rod to rotate, which in turn drives the cylinder to rotate. Simultaneously, the cylinder slides to the right within the groove frame, causing the groove frame to slide downwards on the second slide rod. This movement of the groove frame drives the pressure plate to move towards the tea leaves until the pressure plate reaches the appropriate position, thus achieving the purpose of adjusting the kneading pressure. This method adapts to the pressure requirements of various tea kneading processes and eliminates the need for manual adjustment of the pressure plate height.

[0013] Through the cooperation of the tea plasticity adjustment structure and the first shell, the output shaft of the first servo motor rotates, driving the threaded rod to rotate. The rotation of the threaded rod drives the second block to move, which in turn drives the second shell to move. The movement of the second shell drives the pressure plate to move to the right. The pressure plate moves from the left end of the threaded rod to its midpoint. The small diameter of the rotation means that the tea leaves have little space to move during kneading, and the squeezing force on the tea leaves is relatively concentrated. The tea leaves frequently squeeze and rub against each other, constantly tumbling in a limited space, causing the tea leaves to gradually curl tightly and eventually form a spiral shape. When the pressure plate moves from the midpoint of the threaded rod to its right end, it can provide a wider movement path for the tea leaves during rotation, allowing the tea leaves to be gradually stretched and straightened, and then kneaded into long strips, thereby achieving the purpose of shaping different shapes during tea leaf kneading.

[0029] Working principle:

[0030] Tea processing operations using a tea rolling machine with controllable rolling pressure:

[0031] Adjustment of kneading pressure:

[0032] The operator pours the tea leaves to be kneaded onto disc 7 and starts the third servo motor 901. The third servo motor 901 is connected to a battery via wires. The battery has a switch that is connected to an external remote control device. The output shaft of the third servo motor 901 rotates, driving the worm gear 902 to rotate (e.g., ...). Figure 3 The worm gear 902 rotates, driving the worm wheel 903 to rotate. Furthermore, the worm wheel and worm gear have a self-locking characteristic to prevent displacement of the pressure plate during operation. The rotation of the worm wheel 903 drives the connecting rod 904 to rotate, which in turn drives the cylinder 905 to rotate. Simultaneously, the cylinder 905 slides to the right within the groove frame 906, causing the groove frame 906 to slide downwards on the second slide rod 907. The movement of the groove frame 906 drives the pressure plate 10 towards the tea leaves. The pressure plate 10 exerts pressure on the tea leaves upon contact. The greater the distance the pressure plate 10 descends, the greater the pressure. By controlling the distance the pressure plate 10 moves, the pressure required for kneading the tea leaves is adjusted. When the pressure plate 10 reaches the required pressure for kneading, the third servo motor 901 is turned off, achieving the purpose of adjusting the kneading pressure of the tea leaves. This method adapts to the pressure requirements of various tea leaves during kneading and eliminates the need for manual adjustment of the pressure plate height.

[0033] Tea leaf rolling:

[0034] When the external power supply of the second servo motor 6 is connected and the second servo motor 6 is started, the output shaft of the second servo motor 6 rotates, driving the first housing 4 to rotate (e.g., Figure 2 The first shell 4 rotates, which drives the second shell 8 to rotate. The second shell 8 rotates, which drives the pressure plate 10 to rotate. The rotation of the pressure plate 10 performs a kneading operation on the tea leaves.

[0035] Plasticity adjustment of tea leaves: The different shapes of tea leaves during rolling affect the release and fusion of the substances contained in the tea leaves. When brewing, spiral-shaped tea leaves release their contents slowly due to their curled structure, resulting in a mellow and lasting tea soup. Long strip-shaped tea leaves have different degrees of cell wall breakage and release rates, which can produce a refreshing and mellow taste.

[0036] The first servo motor 501 is started. The first servo motor 501 is connected to a battery via a wire. A switch is installed on the battery, which is connected to an external remote control device. The output shaft of the first servo motor 501 rotates, driving the threaded rod 502 to rotate (e.g., ...). Figure 5 The rotation of the threaded rod 502 causes the threaded block 503 to move. The movement of the threaded block 503 causes the first block 504 to slide to the right on the first slide rod 505. The first block 504 limits the movement of the threaded block 503, preventing it from rotating with the rotation of the threaded rod 502. The movement of the first block 504, through the threaded block 503, causes the second block 506 to move. The movement of the second block 506 causes the second housing 8 to move. The movement of the second housing 8 causes the pressure plate 10 to move to the right. When the pressure plate 10 moves from the left end of the threaded rod 502 to its midpoint, the circle formed by the rotation of the pressure plate 10... A smaller diameter of the rolling circle means less space for the tea leaves to move during kneading. The pressure on the tea leaves is relatively concentrated, and the tea leaves are frequently squeezed and rubbed against each other, constantly tumbling in a limited space, causing the tea leaves to gradually curl tightly and eventually form a spiral shape. When the pressure plate 10 moves from the midpoint of the threaded rod 502 to its right end, the diameter of the circle formed by the rotation of the pressure plate 10 increases. The larger diameter of the kneading drum can provide a wider movement path for the tea leaves during rotation, allowing the tea leaves to be gradually stretched and straightened, and then kneaded into long strips, thereby achieving the purpose of shaping different shapes during the kneading of tea leaves.

[0037] After the tea leaves are kneaded, turn off all power and remove the kneaded tea leaves. This completes the working process of the tea kneading machine with controllable kneading pressure.
