Abstract
Description
Technical Field
[0001] This invention relates to the field of tea processing and production, and in particular to a tea-encircling device and a granular tea-frying machine. Background Technology
[0002] Frying tea leaves is a crucial step in tea production. Existing granular tea frying machines pour tea leaves into a wok equipped with a heating device. The tea leaves are then fried by the oscillation of the frying plate, which compresses, rubs, and causes thermal shrinkage during dehydration, thus shaping the tea. The transmission mechanism of the frying plate is connected to the frying plate via a crank-driven shaft, transmitting power to switch between different oscillation amplitudes. Because the tea leaves tumble and fly around during the frying plate's oscillation, guard plates are typically added to the edge of the wok to prevent them from falling. However, this structure can obstruct the wok's rotation when the tea leaves are discharged, necessitating manual unloading. Summary of the Invention
[0003] This invention addresses the shortcomings of existing technologies by providing a tea-encircling device and a granular tea-frying machine, achieving automatic tea frying and automatic discharge, improving production efficiency, reducing tea loss, and ensuring high reliability. By incorporating a protective plate to reduce tea loss during frying, and with a tilting mechanism that drives the protective plate away from the pot body to avoid interference with the pot's tilting, automatic discharge is achieved, reducing labor costs and effectively improving production efficiency.
[0004] Therefore, the first objective of the present invention is to provide a tea-serving device.

The granular tea-frying machine includes a pot body, and the tea-encircling device includes a first guard plate and a flipping mechanism. The lower end of the first guard plate is connected to the edge of the pot body. The flipping mechanism is used to control the rotation of the first guard plate so that the first guard plate has a first working position connected to the edge of the pot body and a second working position separated from the edge of the pot body.

[0008] In one technical solution of the present invention, the height of the first guard plate gradually increases from the discharge section of the pot body to the frying section.
[0009] In one technical solution of the present invention, two second guard plates are open, with the opening direction facing the discharge direction of the pot body.

[0023] The following reference Figures 1 to 9 The technical solutions of some embodiments of the present invention are described below.
[0024] Embodiments of the present invention provide a tea-serving device 100, such as... Figures 1 to 6 As shown, to prevent tea leaves from falling out of the granular tea frying machine 200, the granular tea frying machine 200 includes a pot body 210, and the tea surrounding device 100 includes a first guard plate 110 and a flipping mechanism 120; the lower end of the first guard plate 110 is connected to the edge of the pot body 210; the flipping mechanism 120 is used to control the rotation of the first guard plate 110 so that the first guard plate 110 has a first working position connected to the edge of the pot body 210 and a second working position separated from the edge of the pot body 210.
[0025] For example, the first guard plate 110 has an arc-shaped plate structure.
[0026] For example, the first guard plate 110 has a U-shaped opening structure.
[0027] For example, the first guard plate 110 surrounds the entire edge of the pot body 210.
[0028] For example, the first guard plate 110 surrounds the edge of the frying section of the pot body 210. It can be understood that the pot body 210 is divided into a frying section and a discharge section by the position of the frying plate shaft 220.
[0029] For example, connection positioning blocks can be provided on the body of the first guard plate 110 and the body of the pot 210 respectively to prevent the connection position from shifting.
[0030] For example, the first guard plate 110 surrounds the edge of the entire frying section and part of the discharge section of the pot body 210.
[0031] During the tea-frying process, as the frying plate swings, the tea leaves tumble inside and above the pot 210. When the tea leaves come into contact with the first guard plate 110, the first guard plate 110 guides the tea leaves back to the pot 210, forming a physical barrier to intercept the rising tea leaves, reducing tea leakage and improving the uniformity of frying. The lower end of the first guard plate 110 forms a continuous contact surface with the edge of the pot 210, eliminating gaps and preventing tea leaves from getting stuck, further reducing the tea leakage rate and improving the uniformity of frying. The tea-encircling device 100 is also equipped with a flipping mechanism 120 connected to the first guard plate 110. When frying the tea leaves, the first guard plate 110 is located at the edge of the pot 210. When the tea leaves are finished frying and need to be discharged, the flipping mechanism 120 drives the first guard plate 110 to move away from the pot 210, avoiding the space required for the pot 210 to flip, and avoiding interference between the first guard plate 110 and other components, thus achieving automatic discharge.
[0032] In some embodiments of this application, such as Figure 2 As shown, the first guard plate 110 is located in the frying section of the pot body 210. The tea-encircling device 100 also includes a second guard plate 130, which is located in the discharge section of the pot body 210, and the lower end of the second guard plate 130 is fixedly connected to the pot body 210.
[0033] The first guard plate 110 and the second guard plate 130 are designed separately. The first guard plate 110 is movably set at the edge of the frying section of the pot body 210, while the second guard plate 130 is fixedly connected to the discharge section of the pot body 210. The two are combined in a dynamic and static manner and are set in separate sections. On the one hand, this increases the mechanical strength of the tea-encircling device 100. When discharging, the flipping mechanism 120 only needs to drive the first guard plate 110 away from the pot body 210, thereby reducing the radius of the center of gravity of the flipping mechanism 120 and increasing the rigidity of the rotating part of the tea-encircling device 100. On the other hand, it improves the discharge guidance. The second guard plate 130 forms a guiding structure, allowing the tea leaves to fall more accurately into the receiving container.
[0034] In some embodiments of this application, the height of the first guard plate 110 gradually increases from the discharge section of the pot body 210 to the frying section.
[0035] Based on the movement trajectory of the tea leaves within the pot 210, the height of the first guard plate 110 is set, which reduces tea leaf loss, saves materials used in the first guard plate 110, optimizes the volume and structure of the first guard plate 110, reduces the force required by the flipping mechanism 120 to apply to the first guard plate 110, and further increases the mechanical strength and stability of the tea-encircling device 100.
[0036] In some embodiments of this application, such as Figure 2 As shown, there are two second guard plates 130 with an opening facing the discharge direction of the pot body 210.
[0037] There are two second guard plates 130, which are respectively located on the two sides of the discharge section of the pot body 210. The opening direction of the two second guard plates 130 is the same as the discharge trajectory of the pot body 210, which not only accurately guides the tea leaves to improve the discharge efficiency, but also optimizes the structural layout of the second guard plates 130.
[0038] In some embodiments of this application, such as Figure 6 As shown, the granular tea frying machine 200 also includes a frying plate shaft 220, which is located above the pot body 210; the first guard plate 110 and the second guard plate 130 are connected at the frying plate shaft 220.
[0039] The mating surfaces of the first guard plate 110 and the second guard plate 130 are precisely positioned at the stir-frying plate shaft 220. This not only seals the gap in the movement of the stir-frying plate and prevents tea leakage, but also optimizes the structural coupling efficiency of the double guard plates, reduces the independent support structure of the connecting parts, and reduces the torque transmission of the stir-frying plate shaft 220 vibration to the guard plates, further enhancing the overall rigidity and long-term reliability of the tea-encircling device 100 under dynamic working conditions.
[0040] In some embodiments of this application, such as Figure 2 As shown, the first guard plate 110 includes a first groove 110a, and the second guard plate 130 includes a second groove 130a. The first groove 110a and the second groove 130a cooperate to allow the stir-frying plate shaft 220 to pass through.
[0041] For example, the first guard plate 110 and the second guard plate 130 are integrally formed, and the joint between the first guard plate 110 and the second guard plate 130 is processed by a CNC laser cutting machine. The first guard plate 110 and the second guard plate 130 are integrally formed, and the material and shape are continuous and smooth. The joint is processed by a CNC laser cutting machine to reduce the roughness of the cut and increase the precision of the contour processing.
[0042] Based on the vibration characteristics of the stir-frying plate shaft 220, the joint of the double guard plates is constructed as a hook-type interlocking structure to achieve dynamic sealing of the gap under vibration conditions, optimize the stress distribution of the joint surface, extend the service life of the tea-encircling device 100 in high temperature and high humidity environments, and avoid interference between the second guard plate 130 and the first guard plate 110 when the second guard plate 130 moves.
[0043] In some embodiments of this application, such as Figure 2 As shown, the flipping mechanism 120 includes a motor 121, a drive gear 122, a driven gear 123, and a rotating shaft 124 connected in sequence; the motor 121 is used to drive the drive gear 122, the drive gear 122 meshes with the driven gear 123, one end of the rotating shaft 124 is connected to the driven gear 123, and the other end of the rotating shaft 124 is connected to the first guard plate 110.
[0044] For example, motor 121 can be a servo motor. Servo motors have high positioning accuracy and fast response speed, which further ensures that when the first guard plate 110 is in the first position, the lower end of the first guard plate 110 forms a continuous contact surface with the edge of the pot body 210, eliminating gaps and preventing tea leaves from getting stuck, thereby reducing tea leakage; and when the first guard plate 110 is in the second position, it prevents the first guard plate 110 from deviating from the preset position.
[0045] The motor 121 drives the rotating shaft 124 through the driving gear 122 and the driven gear 123. The transmission structure is stable and the rotation angle is easy to control.
[0046] In some embodiments of this application, the flipping mechanism 120 further includes: a first sensor, a second sensor, and a positioning member; the positioning member is disposed on the body of the driven gear 123, and the first sensor, the second sensor, and the positioning member cooperate to limit the rotation angle of the driven gear 123.
[0047] For example, the first sensor is located near the positioning element when the driven gear 123 is in its initial position, and the second sensor can be located near the positioning element when the driven gear 123 rotates to a preset angle. The preset angle can be set according to the specific working environment of the granular tea frying machine 200. For example, if a feeding mechanism is set above the granular tea frying machine 200, a preset angle can be specifically set to prevent interference with the feeding mechanism.
[0048] Based on the positioning reliability requirements of the granular tea frying machine 200 under high-frequency vibration conditions, a positioning component is set in the driven gear 123, and the first and second sensors are configured for collaborative detection. This not only achieves arc-loop control of the opening and closing position of the first guard plate 110, but also eliminates malfunctions through dual-channel redundant verification, reduces wear and drift of traditional mechanical limiters, and reduces the risk of system downtime under extreme conditions, ensuring the operational accuracy of the tea-encircling device 100 during its service life.
[0049] An embodiment of the present invention provides a granular tea frying machine 200, such as... Figures 6 to 9 As shown, the granular tea frying machine 200 includes a tea-encircling device 100 and a pot frame 230 as described in any of the above embodiments; the tea-encircling device 100 is connected to the pot frame 230.
[0050] The granular tea frying machine 200 of this embodiment includes the tea-encircling device 100 of any of the above embodiments, and thus has all the beneficial effects of the tea-encircling device 100 of any embodiment of the present invention, which will not be repeated here.
[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects.
