Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically to a tea-turning and discharging device. Background Technology

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. Other names include tea, jia, ming, and chuan. Tea leaves contain catechins, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea beverages are one of the world's three major beverages.

[0003] Currently, after tea picking, the tea leaves need to be turned and roasted. For example, during the shaping process, the tea leaves need to be turned and heated to ensure even heating and improve tea quality. One existing tea-turning and roasting mechanism can be... Figure 1 The following diagram illustrates the mechanism: 101 represents the frame; 102 represents a movable plate linearly mounted on the frame; 103 represents a flipping plate hinged to the movable plate at one end; 104 represents a handle at the other end of the movable plate; 105 represents multiple woks mounted on the flipping plate; and 106 represents an external linear drive structure connected to the movable plate, used to drive the movable plate to reciprocate horizontally on the frame, thus flipping and frying the tea leaves inside the woks. However, after frying the tea leaves, this frying mechanism requires a tray of a size adapted to the flipping plate to tightly cover the tea leaves. Figure 1 As shown, on the flipping plate, a person pulls the handle to rotate the plate around its hinge point. During rotation, all the tea leaves in the wok fall onto the tray, thus discharging the tea. This method requires manual assistance, and during the flipping process, a single worker needs to use both hands or two or more workers need to coordinate to discharge the tea. The operation is relatively cumbersome and the discharge efficiency is low.

[0004] To address this problem, we propose a tea leaf turning and discharging device. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a tea leaf turning and discharging device. This device, through the setting of a driving component and a rotating structure frying pot, enables the frying pot to perform a turning action of a corresponding amplitude under the action of the driving component, which not only achieves uniform turning of the tea leaves, but also achieves quick and convenient discharging of the tea leaves.

[0006] To solve the above problems, this utility model provides the following technical solution:

[0007] A tea leaf turning and discharging device includes a support plate capable of reciprocating linear motion and a frying pan rotatably mounted on the support plate. The support plate has a through groove for accommodating the frying pan, and a driving member is provided on the support plate to drive the frying pan to rotate, so that the frying pan can turn at a corresponding angle within the through groove.

[0008] As a further embodiment of this utility model: both ends of the frying pan are fixedly provided with rotating shafts, and the two rotating shafts are arranged coaxially. The two rotating shafts are respectively rotated on two opposite sides of the through groove, and the driving component is used to drive either of the rotating shafts to rotate.

[0009] As a further embodiment of this utility model: the driving component includes an electric push rod fixedly mounted on the support plate and a rack movably mounted on the support plate. One end of the rack is fixedly connected to the piston rod of the electric push rod. A gear that meshes with the rack is fixedly sleeved on the rotating shaft so that the rotation of the rotating shaft is achieved by the gear when the piston rod drives the rack to move.

[0010] As a further embodiment of this utility model: the driving component includes a driving motor fixedly mounted on the support plate, a driving sprocket is provided on the output shaft of the driving motor, a driven sprocket is provided on the rotating shaft, and the driving sprocket and the driven sprocket are arranged coaxially. A chain is sleeved between the driven sprocket and the driving sprocket so that when the driving sprocket rotates, the rotating shaft is rotated by relying on the driven sprocket.

[0011] As a further embodiment of this utility model: the frying pan is composed of a lower semi-circular cylindrical body and an upper extended opening, and the rotating shaft is located at the middle position of the end of the frying pan.

[0012] As a further embodiment of this utility model, the device also includes a frame with a sliding groove, the bearing plate being slidably mounted on the sliding groove, and the linear motion direction of the bearing plate being perpendicular to the rotation axis of the frying pan.

[0013] As a further embodiment of this utility model: heating elements are fixedly arranged in a circumferential array on the outer side of the frying pan.

[0014] As a further embodiment of this invention, the device also includes a collection box disposed below the frying pan.

[0015] As a further aspect of this invention, the device also includes a power source for driving the support plate to perform linear reciprocating motion.

[0016] As a further aspect of this invention, the device also includes a conveyor belt for feeding tea leaves into the frying pan.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This device combines the reciprocating linear motion of the support plate with the rotational motion of the frying pan to achieve uniform turning of tea leaves and automated discharge. During the frying process, the through-groove design allows the frying pan to move with the support plate and rotate at an angle, improving frying efficiency and avoiding the localized overheating problem of traditional fixed frying pans. After frying, the drive unit directly controls the frying pan to rotate significantly, achieving automated discharge, simplifying the operation process, reducing the need for manual intervention, and making it suitable for large-scale tea processing scenarios.

[0019] 2. The coaxial shaft design at both ends ensures stable rotation of the wok, avoiding bearing wear or wok body misalignment caused by unilateral force. The shafts are positioned on both sides of the through groove, enhancing structural symmetry and extending the service life of the equipment; the drive unit only needs to drive either shaft to rotate the entire wok, reducing energy consumption and simplifying the control system.

[0020] 3. The combination of electric push rod and rack and pinion drive is simple and reliable, allowing precise control of the shaft rotation angle and adapting to the stirring needs of different tea varieties. The rack and pinion meshing transmission has high efficiency and fast response speed, and the electric push rod stroke is adjustable, facilitating precise start and stop of the flipping action. This design has low maintenance costs and is suitable for tea processing environments with high humidity and high dust levels.

[0021] 4. The sprocket and chain drive system is suitable for long-distance or high-torque scenarios. The flexibility of the chain can buffer the impact force when the wok is started and stopped, reducing mechanical vibration. The coaxial arrangement of the driving and driven sprockets ensures transmission synchronization and avoids wok rotation deviation. Chain drives are easy to expand and can be adapted to multi-wok production lines to increase processing capacity.

[0022] 5. The semi-circular cylindrical structure facilitates the parabolic motion of tea leaves during stir-frying, improving mixing uniformity; the extended opening design allows for concentrated flow during discharging, reducing residue. The centrally located rotating shaft ensures that the pot's center of gravity coincides with the rotation axis, reducing drive energy consumption, enhancing motion stability, and preventing eccentric material accumulation.

[0023] 6. The sliding fit between the chute and the support plate ensures precise linear motion trajectory and avoids mechanical interference caused by deviation. The direction of movement of the support plate is perpendicular to the rotation axis of the frying pan, forming a compound motion of translation and rotation, which significantly improves the tea leaf turning and coverage.

[0024] 7. The circumferential array of heating elements ensures uniform heating of the wok, avoiding the temperature gradient problem caused by traditional bottom heating. The heating elements are directly fixed to the outer wall of the wok, resulting in high heat conduction efficiency and easy zone temperature control, adapting to the temperature profile requirements of different processes such as green tea and black tea.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 2-4 As shown, a tea leaf turning and discharging device includes a frying component for frying tea leaves, a feeding component for conveying raw tea leaves to the frying component, and a collecting component for collecting the fried tea leaves. The three components are described below:

[0034] The frying assembly includes a frame 8, with a slide groove 9 on the top of the frame 8. A support plate 1 is slidably mounted on the slide groove 9. Guided by the linear motion of the slide groove 9, the support plate 1 can move along the length of the slide groove 9. A through groove 3 is formed on the support plate 1, and a rotating shaft 4 is rotatably mounted on each of the two opposite sides of the through groove 3. The two rotating shafts 4 are arranged coaxially, and a frying pan 2 is fixedly mounted between the two rotating shafts 4. A driving component is also provided on the support plate 1 to drive one of the rotating shafts 4 to rotate, thereby realizing the rotation of the frying pan 2. Preferably, the rotation axis of the frying pan 2 is perpendicular to the movement direction of the support plate 1.

[0035] Therefore, the tumbling and rotating motion of the frying pan 2 can have the following two working modes:

[0036] 1) First working mode: After the tea raw materials are conveyed into the frying pot 2 by the feeding component, the frame 8 can be driven to reciprocate linearly on the slide 9. At the same time, the driving component drives the frying pot 2 to make a small-amplitude reciprocating rotation. The opening of the frying pot 2 is always facing upward. The tea leaves in the frying pot 2 are subjected to both the horizontal action applied by the frame 8 and the rotational action applied by the frying pot 2. Under the integration of the two actions, the tea leaves can be turned evenly and the turning range is larger, so as to achieve a better frying effect.

[0037] 2) Second working mode: After the tea leaves are stir-fried as described above, the stir-frying pot 2 can be rotated in a large range using the drive component until the opening of the stir-frying pot 2 faces downward, so as to realize the quick and convenient discharge of the tea leaves. It does not require manual discharge as in the existing technology, thus improving the efficiency of stir-frying.

[0038] like Figure 4 As shown, in the above-mentioned structural design of the frying pan 2, the frying pan 2 consists of a lower semi-circular cylindrical body 201 and an upper extended opening 202, with the rotating shaft 4 located at the middle of the end of the frying pan 2. Preferably, this application can provide multiple frying pans 2, arranged side by side in parallel. When there are multiple frying pans 2, the driving components can also be restricted. For example, a single driving component can drive multiple frying pans 2 to rotate, or each driving component can be arranged in a one-to-one correspondence with each frying pan 2, operating independently without interference.

[0039] like Figure 2 As shown, for the design of the driving component, this application can select any driving component in the prior art, such as belt drive, etc. The present application proposes the following design: the driving component includes an electric push rod 5 fixedly mounted on the support plate 1 and a rack 6 movably mounted on the support plate 1. One end of the rack 6 is fixedly connected to the piston rod of the electric push rod 5. A gear 7 that meshes with the rack 6 is fixedly sleeved on the rotating shaft 4 so that when the piston rod drives the rack 6 to move, the rotation of the rotating shaft 4 is realized by the gear 7.

[0040] Alternatively, the drive component may be designed as follows: the drive component includes a drive motor fixedly mounted on the support plate 1, the output shaft of the drive motor is provided with a drive sprocket, the rotating shaft 4 is provided with a driven sprocket, and the drive sprocket and the driven sprocket are arranged coaxially, and a chain is sleeved between the driven sprocket and the drive sprocket so that when the drive sprocket rotates, the rotating shaft 4 is rotated by relying on the driven sprocket.

[0041] Typically, a heating source is positioned below the frying pan 2 to heat it. However, in this design, the heating source is positioned below the frying pan 2. Instead, a heating element (e.g., a heating wire) 10 is installed outside the frying pan 2. The heating element 10 directly transfers heat to the frying pan 2 through heat conduction. Furthermore, multiple heating elements 10 can be arranged in a circumferential array to achieve uniform heating of the frying pan 2. This uniform heating design, combined with the uniform turning of the tea leaves, allows for better frying of the tea, ensuring its quality.

[0042] 2. The feeding component includes a conveyor belt, the end of which is located above the frying pot 2. When the conveyor belt is working, its end can transport the tea raw materials into the frying pot 2. Combined with the aforementioned automated discharge method, the added feeding component can further improve the automation level of this device.

[0043] 3. The collection component includes a collection box 11, which is placed below the frying pan 2. When the frying pan 2 rotates significantly to discharge the tea, the collection box 11 can collect and temporarily store the fried tea leaves. After a certain amount is collected, the tea leaves can be further processed.

[0044] It should be noted that, regarding the arrangement of the moving parts that drive the support plate 1, this application also includes a power source 12 for driving the support plate 1 to perform linear reciprocating motion. The power source 12 can be designed using conventional techniques in the prior art, such as a crank-slider mechanism. To avoid unnecessary detail, the specific connection methods and layout relationships will not be elaborated here.

[0045] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
