Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tea production equipment, specifically to a fixation device. Background Technology
[0002] Fixing (or killing the green) is a crucial step in tea processing. As one of the initial processing steps for green tea, yellow tea, black tea, oolong tea, pu-erh tea, and some red teas, its main purpose is to use high temperatures to destroy and deactivate the oxidase activity in fresh leaves, inhibiting the enzymatic oxidation of tea polyphenols and other compounds, evaporating some of the moisture from the leaves, softening them, and making them easier to roll and shape. Simultaneously, this process also helps to remove any grassy odor and promote the formation of a pleasant aroma, making it a key step in the development of tea quality.
[0003] Referring to existing technology CN219920159U, a withering device for green tea production includes a support frame, a drying barrel assembly rotatably mounted on the support frame, and an electric heating component slidably mounted relative to the support frame. The electric heating component can be moved to close the outer side of the drying barrel assembly. The drying barrel assembly includes an inner cylinder and an outer cylinder coaxially sleeved together, defining an annular cavity for containing tea leaves. Both the inner and outer cylinders have porous and breathable structures to facilitate steam discharge. The outer wall of the inner cylinder has an outwardly extending inner paddle, and the inner wall of the outer cylinder has an inwardly extending outer paddle. The outer cylinder has an openable and closable movable piece. The support frame has a motor for driving the outer cylinder to rotate. A torsion spring is coaxially connected between the outer cylinder and the inner cylinder. The support frame has a brake assembly that acts on the inner cylinder. In the withering process, this utility model continuously repeats a process similar to "tossing and steaming." By controlling the action interval of the brake assembly, the effect of more tossing and less steaming can be achieved.
[0004] Specifically, the outer and inner pry bars create a relatively clamping action, slightly tightening the tea leaves and producing a "steaming" effect. However, the tea leaves tumble randomly inside the inner tube, and only a small amount falls between the outer and inner pry bars during this tumbling process, thus reducing the "steaming" effect. Utility Model Content
[0005] The present invention aims to provide a fixation device to solve the technical problem in the prior art where only a small amount of tea leaves fall between the outer and inner picks and are clamped, resulting in a poor "squeezing" effect.
[0006] To solve the above problems, this utility model provides the following technical solution:
[0007] A blanching device includes a roller and a support base, which are rotatably connected. The roller is symmetrically provided with oppositely arranged sliding openings. The support base is symmetrically fixed with cylinders. The movable end of the cylinder drives a connecting seat. A support rod passing through the sliding openings on both sides is rotatably connected between the two connecting seats. The support rod is fixed with a pressure plate facing the bottom of the roller. A motor that drives the support rod to rotate is fixed on one of the connecting seats.
[0008] The working principle and beneficial effects of this utility model:
[0009] This method involves placing the tea leaves to be processed into a drum, where the rotation of the drum tumbles the leaves, allowing them to be fully heated during the process. Simultaneously, a support rod is positioned within a sliding opening, and a pressure plate is located inside the drum, ensuring that the support rod and pressure plate do not obstruct the drum's rotation. During tumbling, the tea leaves fall onto the pressure plate. At this point, a motor drives the support rod to rotate, causing the pressure plate to flip 180 degrees, pouring the tea leaves downwards onto the drum, achieving a "throwing" effect. Then, the drum stops rotating, and a cylinder drives the support rod to move downwards through the sliding opening. The support rod then moves the pressure plate towards the bottom of the drum, compressing the tea leaves between the pressure plate and the drum, achieving a "steaming" effect.
[0010] In this solution, after the drum stops rotating, the tea leaves remain at the bottom of the drum and are in a static state. The tea leaves are then squeezed by the pressure plate to achieve the "squeezing" effect. At this time, all the tea leaves can be squeezed, which is different from the existing technology where only a small number of tea leaves are squeezed. This solution improves the "squeezing" effect and further enhances the withering effect.
[0011] The optimized design features a pressure plate with the same shape as the bottom of the roller. When the pressure plate presses against the bottom of the roller, the fit between the pressure plate and the bottom of the roller is perfect, thus achieving a better "steaming" effect.
[0012] The optimized design uses a servo motor. The self-locking mechanism of the servo motor is used to lock the rotation of the support rod.
[0013] The roller is optimized by having a discharge gate. Feeding and discharging are performed through the discharge gate.
[0014] The optimized design incorporates heating wires inside the pressing plate. These wires heat the pressing plate, raising its temperature and pressing it against the tea leaves, thus enhancing the "simmering" effect.
[0015] The optimized support rod is an inverted L-shape. Using an inverted L-shaped rod reduces the size of the sliding opening. Attached Figure Description
[0016] Figure 1 This is a schematic diagram of the internal structure of a blanching device according to the present invention;
[0017] Figure 2 for Figure 1 A schematic diagram of the structure of tea leaves when thrown downwards;
[0018] Figure 3 for Figure 1 A schematic diagram of the structure when the medium pressure plate presses the tea leaves. Detailed Implementation
[0019] The following detailed description illustrates the specific implementation method:
[0020] The reference numerals in the accompanying drawings include: gear 1, drive motor 2, support base 3, cylinder 4, connecting base 5, servo motor 6, roller 7, gear ring 8, pressure plate 9, tea leaves 10, sliding opening 11, and support rod 12.
[0021] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.
[0022] Example: A blanching device, such as Figure 1 As shown, it includes a roller 7 and a support base 3, which are rotatably connected. A gear ring 8 is fixedly sleeved on the roller 7, and a drive motor 2 is fixedly mounted on the support base 3. The drive motor 2 drives a gear 1 that meshes with the gear ring 8. That is, the drive motor 2 drives the gear 1 to rotate, and the gear 1 drives the roller 7 to rotate through the gear ring 8.
[0023] Sliding openings 11 are provided on both the left and right sides of the roller 7, with the sliding openings 11 facing each other. Cylinders 4 are symmetrically fixed to the support base 3. The movable end of the cylinder 4 drives a connecting seat 5. A servo motor 6 is fixedly mounted on the left connecting seat 5, and a support rod 12 is fixedly sleeved on the movable end of the servo motor 6. Another support rod 12 is rotatably connected to the right connecting seat 5. The two support rods 12 are coaxial. The support rod 12 is inverted L-shaped, and a pressure plate 9 is fixedly connected between the ends of the two support rods 12. The servo motor 6 is a Nidec MZ751A200 servo motor manufactured by Nidec Corporation.
[0024] This method involves placing the tea leaves 10 to be processed into the drum 7, and using the rotation of the drum 7 to tumble the tea leaves 10. During the tumbling process, the tea leaves 10 are fully heated. The method for heating the tea leaves 10 refers to the existing technology CN219920159U, a processing device for green tea production.
[0025] Meanwhile, the support rod 12 is located inside the sliding opening 11, and the pressure plate 9 is located inside the roller 7, thus ensuring that the support rod 12 and the pressure plate 9 do not obstruct the rotation of the roller 7. During the tumbling process, the tea leaves 10 fall onto the pressure plate 9, as... Figure 2As shown, at this time, the servo motor 6 drives the support rod 12 to rotate, and the support rod 12 drives the pressure plate 9 to flip 180 degrees, causing the tea leaves 10 to fall downwards onto the drum 7, thus achieving the technical effect of "throwing". Then the drum 7 stops rotating, as... Figure 3 As shown, the cylinder 4 drives the support rod 12 to move downward at the sliding opening 11. The support rod 12 drives the pressure plate 9 to move towards the bottom of the drum 7, and the tea leaves 10 are pressed between the pressure plate 9 and the drum 7 to achieve the "steaming" effect. After "steaming" for a period of time, the pressure plate 9 detaches from the tea leaves 10, and the tea leaves 10 can be removed from the drum 7.
[0026] In this solution, when the drum 7 stops rotating, the tea leaves 10 remain at the bottom of the drum 7 and are in a static state. Then, the pressure plate 9 squeezes the tea leaves 10 to achieve the "squeezing" effect. At this time, all the tea leaves 10 can be squeezed, which is different from the existing technology where only a small number of tea leaves 10 are squeezed. This solution improves the "squeezing" effect and further enhances the fixation effect.
[0027] Furthermore, a heating wire is fixedly installed inside the pressure plate 9. The heating wire heats the pressure plate 9, causing it to heat up and press against the tea leaves, thus enhancing the "steaming" effect.
[0028] Servo motor 6 is a commonly used mechanical transmission component in this field. It is a motor that converts electrical signals into mechanical motion. By controlling the motor's current, it can rotate the motor to a desired position and maintain that position. Furthermore, servo motor 7 also has a self-locking function. The self-locking principle is mainly achieved by using an electromagnetic brake built into servo motor 6 to lock the output shaft of servo motor 6. In the event of a power outage or shutdown of servo motor 6, the electromagnetic brake automatically activates and locks the output shaft of servo motor 6, keeping the support rod 12 stationary.
[0029] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
