Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, specifically to a tea processing device that facilitates rapid fixation of the green leaves. Background Technology
[0002] With the continuous development of the economy, people's living standards have greatly improved, and the demand for tea has also continued to increase. During the processing of tea, a fixing device is needed for fixing. The existing tea fixing devices are basically all based on the method of rotating drum heating.
[0003] Existing tea fixing devices typically discharge the fixed tea leaves from the fixing cylinder by tilting the device at a certain angle. However, because the inner wall of the fixing cylinder is equipped with multiple sets of spiral stirring plates, the blade structure directly obstructs the falling tea leaves, resulting in a blocked discharge path and a slowed discharge speed. Simultaneously, the juice released by the tea leaves during the fixing process causes them to easily adhere to the cylinder wall and the surface of the stirring plates. Even after drying, some tea leaves stubbornly adhere to these areas, resulting in incomplete discharge. The remaining adhered tea leaves are prone to charring during subsequent processing due to continued heating, thus affecting the quality of the next batch of tea. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a tea processing device that facilitates rapid fixation, in order to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tea processing device for rapid fixation, comprising a heating cylinder, a variable frequency motor mounted on one side of the heating cylinder, and a rotating cylinder connected to the output end of the variable frequency motor; a mounting cylinder provided at the top of the heating cylinder; a servo motor mounted on one side of the mounting cylinder; a lead screw connected to the output end of the servo motor; a threaded block threaded onto the outer surface of the lead screw; a mounting ring fixed to one side of the threaded block by a fixing rod; a rotating ring rotatably connected to the inner side of the mounting ring; and an extension extending into the rotating cylinder fixed to one side of the rotating ring. The rotating cylinder has a stirring plate, a scraper fixed to one side of the stirring plate, a wedge block fixed to one side of the scraper, a wedge groove opened on one side of the interior of the rotating cylinder, the wedge block being adapted to the wedge groove, a fixed cylinder provided on the outer surface and back of the heating cylinder, and a support frame welded to the bottom of the fixed cylinder, a sliding rod fixed to the inner side of the support frame, and a sliding sleeve sleeved on the outer surface of the sliding rod, a screening frame welded to one side of the sliding sleeve, a drive motor and a connecting plate respectively installed on one side of the support frame, the outer surface of the connecting plate being connected to the screening frame by a spring, and a cam installed at the output end of the drive motor.
[0006] Furthermore, the inner wall of the heating cylinder is equipped with multiple sets of heating rods, which are distributed in a ring shape at equal intervals.
[0007] By adopting the above technical solution, multiple heating rods are distributed in a ring at equal intervals, which can form a uniform heat source around the plant, ensuring that the temperature in each area of the heating cylinder is consistent, so that the tea leaves are heated evenly during the fixation process, and improving the stability of fixation quality.
[0008] Furthermore, a control panel is installed on the outer surface of the fixed cylinder, and the variable frequency motor, heating rod, drive motor and servo motor are all electrically connected to the control panel.
[0009] By adopting the above technical solutions, the control panel can achieve centralized control of the variable frequency motor, heating rod, drive motor and servo motor.
[0010] Furthermore, a slip ring is fixed to the outer wall of the rotating cylinder, and a sliding groove is fixed to the inner wall of the heating cylinder, with the rotating cylinder slidingly engaging with the slip ring and the sliding groove.
[0011] By adopting the above technical solution, the slip ring and the slide groove form a sliding fit, providing precise guidance for the movement of the rotating cylinder, effectively limiting its radial offset, ensuring smooth rotation or displacement, and improving the stability of equipment operation.
[0012] Furthermore, the stirring plates are provided in multiple sets, and the multiple sets of stirring plates are distributed in a ring shape at equal intervals.
[0013] By adopting the above technical solution, the tea leaves can be evenly contacted and turned during rotation, avoiding local accumulation, further improving the uniformity of heating and turning of the tea leaves during the fixation process, and ensuring stable fixation results.
[0014] Furthermore, the edges of the stirring plate and the scraper are in contact with the inner wall of the rotating cylinder.
[0015] By adopting the above technical solutions, close contact can ensure that there are no dead corners in the turning process; and when discharging, the scraper can closely adhere to the inner wall to remove residue, further ensuring the thoroughness of tea cleaning and improving the operating efficiency of the equipment.
[0016] Furthermore, two sets of guide rods are fixed on the outer surface of the mounting ring, and the guide rods slide in conjunction with the fixed cylinder.
[0017] By adopting the above technical solution, a dual guide is formed to limit the lateral sway of the mounting ring, ensuring that it moves the stirring plate and scraper accurately and smoothly; at the same time, it can also work together to bear the weight of the stirring plate and scraper when they move out of the rotating cylinder, avoiding deformation of the components due to the load.
[0018] Furthermore, the screening frame is inclined at an angle of 15°.
[0019] By adopting the above technical solution, the tea leaves are guided by gravity to slide slowly along the inclined direction, avoiding accumulation on the screening surface. The reasonable inclination angle ensures that the tea leaves have sufficient contact time with the screening surface, ensuring that the broken pieces and impurities are fully separated.
[0020] Furthermore, the spring is made of manganese steel.
[0021] By adopting the above technical solution, the spring has a longer service life due to its high strength and excellent elasticity and toughness.
[0022] In summary, the present invention has the following main advantages:
[0023] 1. This utility model comprises a lead screw, a threaded block, a fixed rod, an mounting ring, a rotating ring, a stirring plate, a scraper, a wedge block, and a wedge groove. During normal withering, a variable frequency motor drives the rotating drum to rotate. The wedge groove and the wedge block work together to drive the scraper, the stirring plate, and the rotating ring to rotate. The stirring plate, following the rotation of the rotating drum, can turn over the tea leaves inside, making the withering more uniform. After withering, the servo motor rotates, causing the lead screw to rotate. This causes the threaded block to drive the mounting ring to move through the fixed rod. The movement of the mounting ring causes the rotating ring, the stirring plate, and the scraper to move. The scraper can push all the tea leaves out of the rotating drum, making the discharge faster and more thorough, increasing the speed of the withering process, and effectively avoiding the problems of tea leaf adhesion and slow discharge speed in traditional devices. At the same time, after the stirring plate moves out of the rotating drum with the rotating ring, it is easy for workers to quickly clean the residual tea leaves on the surface, preventing the residual tea leaves from charring and affecting the quality of subsequent batches.
[0024] 2. This utility model is equipped with a drive motor, a screening frame, a spring, a slide rod, a sliding sleeve, and a cam. During the discharge process, the tea leaves naturally fall onto the screening frame, and the drive motor drives the cam to rotate. By utilizing the intermittent compression of the screening frame by the cam and the reset effect of the spring, the screening frame forms a stable reciprocating oscillation on the slide rod through the sliding sleeve. This can efficiently separate foreign objects such as broken pieces and impurities from the tea leaves, thereby improving the purity and appearance of the finished tea product.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0033] The embodiments of this utility model will be described below based on its overall structure.
[0034] Example 1: A tea processing device for rapid fixation, such as... Figures 1-5 As shown, the device includes a heating cylinder 1. A variable frequency motor 28 is mounted on one side of the heating cylinder 1, and the output end of the variable frequency motor 28 is connected to a rotating cylinder 20. A slip ring 26 is fixed to the outer wall of the rotating cylinder 20, and a sliding groove 25 is fixed to the inner wall of the heating cylinder 1. The rotating cylinder 20 slides through the slip ring 26 and the sliding groove 25, providing precise guidance for the movement of the rotating cylinder 20. This effectively limits its radial offset, ensuring smooth rotation or displacement and improving the stability of the equipment operation. A mounting cylinder 5 is provided on the top of the heating cylinder 1, and a servo motor 13 is mounted on one side of the mounting cylinder 5. The output end is connected to a lead screw 14, and a threaded block 15 is threadedly connected to the outer surface of the lead screw 14. A mounting ring 17 is fixed to one side of the threaded block 15 by a fixing rod 16, and a rotating ring 19 is rotatably connected to the inner side of the mounting ring 17. A stirring plate 21 extending into the interior of the rotating cylinder 20 is fixed to one side of the rotating ring 19. A scraper 22 is fixed to one side of the stirring plate 21, and a wedge block 23 is fixed to one side of the scraper 22. A wedge groove 18 is opened on one side of the interior of the rotating cylinder 20, and the wedge block 23 is adapted to the wedge groove 18. A fixing cylinder 2 is provided on the outer surface and back of the heating cylinder 1, and a support frame 3 is welded to the bottom of the fixing cylinder 2.
[0035] See Figures 2-3 In the above embodiment, multiple sets of heating rods 24 are installed on the inner wall of the heating cylinder 1. The multiple sets of heating rods 24 are distributed in a ring shape at equal intervals, which can form a uniform heat source around the ring, ensuring that the temperature of each area inside the heating cylinder 1 is consistent, so that the tea leaves are heated evenly during the fixation process, and improving the stability of the fixation quality. The outer surface of the fixed cylinder 2 is equipped with a control panel 4, and the variable frequency motor 28, heating rods 24, drive motor 11 and servo motor 13 are all electrically connected to the control panel 4. The control panel 4 can realize centralized control of the variable frequency motor 28, heating rods 24, drive motor 11 and servo motor 13.
[0036] See Figure 2 , Figure 3 and Figure 5 In the above embodiment, the stirring plate 21 is provided in multiple sets, and the multiple sets of stirring plates 21 are distributed in a ring shape at equal intervals. When rotating, they can evenly contact and turn the tea leaves, avoiding local accumulation, further improving the uniformity of heating and turning of the tea leaves during the fixation process, and ensuring stable fixation effect. The edges of the stirring plate 21 and the edges of the scraper 22 are in contact with the inner wall of the rotating cylinder 20. The close contact can ensure that there are no dead corners in the turning. At the same time, the scraper 22 can closely stick to the inner wall to scrape off the residue when discharging, further ensuring the thorough cleaning of the tea leaves and improving the operating effect of the equipment.
[0037] See Figures 1-2 In the above embodiment, two sets of guide rods 27 are fixed on the outer surface of the mounting ring 17, and the guide rods 27 slide in cooperation with the fixed cylinder 2, which can play a dual guiding role for the displacement of the mounting ring 17, effectively limiting its lateral sway, ensuring that the mounting ring 17 moves accurately and stably when it drives the stirring plate 21, scraper 22 and other components to move, and can also bear the gravity when the stirring plate 21 and scraper 22 are displaced out of the rotating cylinder 20.
[0038] Example 2: To facilitate the sieving of tea leaves after fixation and to remove impurities and fragments, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 1 , Figure 2 and Figure 6The inner side of the support frame 3 is fixed with a sliding rod 6, and a sliding sleeve 7 is sleeved on the outer surface of the sliding rod 6. A screening frame 10 is welded to one side of the sliding sleeve 7. A drive motor 11 and a connecting plate 8 are respectively installed on one side of the support frame 3. The outer surface of the connecting plate 8 is connected to the screening frame 10 through a spring 9. The spring 9 is made of manganese steel, which has a longer service life due to its high strength and excellent elasticity and toughness. A cam 12 is installed at the output end of the drive motor 11. The drive motor 11 drives the cam 12 to rotate. The cam 12 intermittently squeezes the screening frame 10. With the reset action of the manganese steel spring 9, the screening frame 10 swings back and forth on the sliding rod 6 through the sliding sleeve 7, efficiently separating the broken pieces and impurities in the tea leaves. The screening frame 10 is inclined at an angle of 15°. Gravity guides the tea leaves to slide slowly along the inclined direction, avoiding accumulation on the screening surface. The reasonable inclination angle ensures that the tea leaves have sufficient contact time with the screening surface, ensuring that the broken pieces and impurities are fully separated.
[0039] The implementation principle of this utility model is as follows: During operation, the operator starts the equipment through the control panel 4 on the outer surface of the fixed cylinder 2. The heating rod 24 starts working to form a uniform surrounding heat source. Then, the frequency conversion motor 28 drives the rotating cylinder 20 to rotate. When the temperature inside the rotating cylinder 20 rises to about 120℃, the operator adds tea leaves into the rotating cylinder 20. After the rotating cylinder 20 rotates, the wedge groove 18 and the wedge block 23 work together to drive the scraper 22, the stirring plate 21, and the rotating ring 19 to rotate. The stirring plate 21 rotates with the rotating cylinder 20 to turn the tea leaves inside, making the fixation more uniform. After the fixation is completed, the servo motor 13 drives the lead screw 14. Rotation causes the threaded block 15 to move the mounting ring 17 via the fixed rod 16. The two sets of guide rods 27 slide against the fixed cylinder 2. The edge of the scraper 22 adheres to the inner wall of the rotating cylinder 20 to push out the tea leaves (the scraper 22 is not completely displaced out of the rotating cylinder 20 to ensure that it is not affected by gravity and will not fall or deform). At the same time as the material is discharged, the staff starts the drive motor 11. The tea leaves will fall onto the inclined screening frame 10. The drive motor 11 drives the cam 12 to rotate. The cam 12 intermittently squeezes the screening frame 10. With the reset action of the manganese steel spring 9, the screening frame 10 swings back and forth on the slide rod 6 through the sliding sleeve 7, efficiently separating the broken pieces and impurities in the tea leaves.
