[0021] This utility model embodiment provides a tea fixing device, such as... Figure 1-4As shown, the tea fixing device includes: a base 1; a support frame 2 fixed to the top of the base 1; a cylinder 3 fixed to the support frame 2 for supporting the tea leaves to be fixed, the cylinder 3 having an opening for providing a passage for the tea leaves to enter and exit; a first protective cover 4 and a second protective cover 5 hinged to the cylinder 3, the first protective cover 4 cooperating with the second protective cover 5 to adjust the size of the opening; a tea-tumbling flap 8 rotatably installed inside the cylinder 3 for turning the tea leaves; a servo motor 14 fixed to the support frame 2 for driving the tea-tumbling flap 8 to rotate, the output shaft of the servo motor 14 being connected to the tea-tumbling flap 8; and an adjustment assembly provided on the cylinder 3 for adjusting the opening and closing of the first protective cover 4 and the second protective cover 5.

[0022] In this embodiment, the base 1 serves as a stable support foundation for the entire blanching device, ensuring the stability of the device during operation. The support frame 2 is used to support and fix components such as the upper cylinder 3, providing structural support and stability. The cylinder 3 is used to support the tea leaves to be blanched. The cylinder 3 has an opening for the tea leaves to enter and exit, and is the main container for the blanching process. The first protective cover 4 and the second protective cover 5 work together to adjust the size of the opening of the cylinder 3, preventing excessive loss of heat and tea aroma during the blanching process. The tea-tumbling plate 8 is used to turn the tea leaves, ensuring that the tea leaves are heated evenly to achieve the blanching effect. At the same time, the rotation of the tea-tumbling plate 8 can also push the tea leaves to a high place, and the falling tea leaves achieve the tossing effect. The reverse rotation of the servo motor 14 can drive the tea-tumbling plate 8 to push the tea leaves out of the cylinder 3. The servo motor 14 is used to drive the tea-tumbling plate 8 to rotate, realizing the automatic turning of the tea leaves, which has the advantages of precise control and stable operation.

[0023] In a further preferred embodiment of this utility model, a group of rotating shafts are rotatably mounted on the cylinder 3, and the first protective cover 4 and the second protective cover 5 are fixed on the rotating shafts. The inner walls of the first protective cover 4 and the second protective cover 5 are each equipped with a silicone strip that can contact the outer wall of the cylinder 3 to increase the sealing degree.

[0024] In this embodiment, the grouped rotating shafts are used to fix the first protective cover 4 and the second protective cover 5. The protective cover can be easily opened or closed by rotating the shafts, which also increases the connection stability between the protective cover and the cylinder 3. In addition, the grouped arrangement of the rotating shafts means that the protective cover can be adjusted more flexibly to adapt to different operating needs. The silicone strip has good elasticity and sealing properties, which can effectively prevent tea leaves from splashing out from the opening during the fixation process, while maintaining the temperature and humidity inside the cylinder 3, which is beneficial to the fixation of tea leaves and the preservation of aroma.

[0025] In a further preferred embodiment of the present invention, the adjusting component includes: a gear 6 fixed on the rotating shaft and meshing with it for transmission; and an electric telescopic rod 7 hinged to the cylinder 3 for adjusting the angle of the second protective cover 5, wherein the output rod of the electric telescopic rod 7 is hinged to the second protective cover 5.

[0026] In this embodiment, gear 6 is used for transmission, which means that when one of the shafts rotates, the other shaft can be driven to rotate synchronously through the meshing of gear 6, realizing the synchronous opening and closing of the first protective cover 4 and the second protective cover 5, improving the convenience and efficiency of operation. At the same time, the transmission of gear 6 has stability and reliability, ensuring the opening and closing accuracy of the protective cover. The introduction of electric telescopic rod 7 realizes the automatic adjustment of the protective cover, further reducing labor intensity. Meanwhile, electric telescopic rod 7 has the characteristics of precise control and stable movement, which can ensure the accuracy of the opening and closing position and angle of the protective cover.

[0027] In a further preferred embodiment of the present invention, the cylinder 3 is provided with an air inlet 11, and a heating mechanism for heating tea leaves is detachably installed inside the air inlet 11. The heating mechanism includes a connecting pipe 16 threadedly installed inside the air inlet 11, a heating box 13 for heating air installed on the connecting pipe 16, and an air pump 12 for outputting airflow disposed on the side of the heating box 13 away from the connecting pipe 16.

[0028] In this embodiment, the air inlet 11 serves as the gas inlet of the heating mechanism, allowing external air to enter the interior of the cylinder 3 to provide the necessary heat source for the tea leaf processing. The heating mechanism is a complete system used to heat the air entering the cylinder 3 through the air inlet 11, thereby indirectly heating the tea leaves. The connecting pipe 16 serves as the connecting channel between the heating mechanism and the cylinder 3, ensuring that the heated gas can smoothly enter the cylinder 3. The heating chamber 13 is used to heat the air entering through the connecting pipe 16, and the air pump 12 is used to output the airflow heated by the heating chamber 13, providing power so that the heated air can continuously and stably enter the cylinder 3, providing a uniform heating effect for the tea leaves.

[0029] In a further preferred embodiment of this utility model, the heating box 13 is provided with a heating wire for heating, and a temperature sensor for monitoring the heating temperature is provided on one side of the heating box 13. The sump flap 8 is in sliding contact with the inner wall of the cylinder 3, and the sump flap 8 is provided with mesh holes for assisting ventilation.

[0030] In this embodiment, the heating wire serves as the main heating element, used to heat the air entering the heating chamber 13 to a suitable temperature for tea leaf fixation. The high heating efficiency of the heating wire ensures that the heating chamber 13 can quickly and stably provide the required heat. The temperature sensor (taking DS18B20 as an example) is used to monitor the temperature inside the heating chamber 13 in real time and transmit the signal to the control system so as to adjust the heating power in a timely manner and ensure temperature stability during the fixation process. The sliding contact plate 8 slides on the inner wall of the cylinder 3. This design allows the sliding contact plate 8 to move more smoothly when flipping, reducing friction with the inner wall of the cylinder 3 and extending its service life. At the same time, the sliding contact also ensures that the sliding contact plate 8 can evenly turn the tea leaves during the flipping process, improving the fixation effect. The mesh allows the heated air to directly contact the tea leaves through the sliding contact plate 8, thereby improving the heating efficiency.

[0031] In a further preferred embodiment of the present invention, the second protective cover 5 is provided with a vent 15 for assisting in the discharge of moisture, the vent 15 is provided with a dustproof net for isolating impurities, and plastic tape for sealing the vent 15 is pasted on the second protective cover 5.

[0032] In this embodiment, during the withering process, the tea leaves release moisture. This moisture can be discharged in time through the vent 15 and the opening, maintaining a dry environment inside the cylinder 3. At the same time, it can keep the inside of the device breathable after cleaning, preventing mold caused by moisture accumulation, and also preventing external impurities from entering the device. When it is not necessary to discharge moisture, the vent 15 can be sealed with plastic tape to maintain a stable temperature and humidity inside the cylinder 3. In addition, the operation of attaching and removing the plastic tape is simple and can be flexibly adjusted according to actual needs.

[0033] In a further preferred embodiment of this utility model, an operating rod 9 connected to the bucket flap 8 is rotatably mounted on the cylinder 3. A limiting block is provided on the operating rod 9. A limiting cylinder that can be sleeved outside the limiting block and used to stabilize the angle of the cylinder 3 is detachably mounted on the support frame 2 by bolts.

[0034] In this embodiment, the operating lever 9 provides the user with an intuitive and easy-to-operate handle, allowing the user to conveniently rotate the cylinder 3 to perform tea leaf turning and fixation operations. At the same time, the design of the operating lever 9 also enhances the stability of the cylinder 3, making it less likely for the tea leaf flap 8 to slip or become out of control during the turning process. The design of the limiting block ensures that the tea leaf flap 8 can be firmly fixed when it is turned to a specific angle, avoiding the problem of tea leaf scattering or uneven fixation caused by the shaking or tilting of the tea leaf flap 8. The cooperation between the limiting cylinder and the limiting block effectively restricts the tea leaf flap 8 to a specific angle range during the turning process, thereby ensuring uniform heating and fixation effect of the tea leaves. In addition, the detachable design of the limiting cylinder allows the user to adjust and replace it as needed, improving the flexibility and applicability of the equipment.

[0035] In a further preferred embodiment of the present invention, the bottom of the base 1 is provided with a moving wheel 10 for assisting the movement of the equipment, the support frame 2 is provided with a storage battery, and the side of the cylinder 3 near the second protective cover 5 is provided with an observation window for displaying the tea's withering status.

[0036] In this embodiment, the introduction of the casters 10 makes the tea fixing device easy to move and transport. Whether in the processing workshop or in the outdoor environment, users can easily move it to the required location, improving the flexibility and portability of the equipment. The battery, as the power supply component of the equipment, ensures that the tea fixing device can still work normally in the absence of external power, which is especially important for outdoor operations or environments with unstable power supply, improving the adaptability and reliability of the equipment. The design of the observation window allows users to intuitively observe the fixing state and process of the tea without opening the cylinder 3, which helps users adjust the fixing parameters in a timely manner to ensure the fixing quality and taste of the tea.

[0037] In summary, compared with related technologies, this device ensures stability and durability through the stable combination of base 1, support frame 2, and cylinder 3. The cooperation of the first protective cover 4 and the second protective cover 5, as well as the setting of the adjustment components, makes the tea leaves entering and exiting and the withering process more convenient and safe. The introduction of heating mechanism and temperature sensor provides precise heating control for the tea leaves, ensuring the stability of the withering temperature. The flipping of the fermentation plate 8 and the design of the vent 15 further improve the withering effect and quality of the tea leaves. In addition, the addition of casters 10, battery, and observation window makes the device more flexible, portable, and easy to operate.
