Description

Technical Field

[0001] This utility model relates to the field of pomegranate leaf tea preparation, specifically a drying device for preparing pomegranate leaf tea. Background Technology

[0002] Currently, in the preparation of pomegranate leaf tea, the drying equipment used to dry the tea leaves mainly includes drying boards and hot air blowers placed around the drying boards. The hot air blowers dry the tea leaves on multiple drying boards in the same environment.

[0003] For example, Chinese patent CN219141314U discloses a drying device for preparing pomegranate leaf tea, including a support base with a through hole at its center. A vertically placed heater is installed inside the through hole, with its central axis coinciding with the central axis of the support base. Two vertically placed support columns are arranged symmetrically about the heater on the outside of the heater. Multiple annular shelves are arranged between the two support columns, fitted onto the outside of the heater. The central axis of the annular shelves coincides with the central axis of the heater. All annular shelves are arranged one after another and parallel to the central axis of the heater. Each annular shelf consists of two horizontally placed semi-annular shelves, which are connected and fixed to the support column on the same side. The bottom of the support column is slidably connected to the support base, and the support column reciprocates radially along the heater. This utility model can solve the defect of limited temperature regulation by adjusting the distance between the drying board and the heater.

[0004] However, in practical applications, existing drying devices can only adjust the overall distance between the annular shelf and the heater by moving the support column, but they do not have any structure for turning over the pomegranate leaf tea in the semi-annular shelf. As a result, the tea leaves are always in a static state during the drying process. The tea leaves near the bottom of the shelf or those that are stacked thickly cannot make sufficient contact with the hot air, which easily leads to incomplete drying in some areas. In addition, each semi-annular shelf has a certain width, and there is a natural radial distance difference between the inner and outer ring sides and the heater. This causes the tea leaves in different positions within the same semi-annular shelf to receive different amounts of heat. The tea leaves on the inner ring side are heated to a significantly higher temperature than those on the outer ring side. Ultimately, this results in inconsistent drying levels of pomegranate leaf tea in the same batch and on the same shelf, which seriously affects the overall quality of the pomegranate leaf tea.

[0013] Compared with the prior art, this utility model provides a drying device for preparing pomegranate leaf tea, which has the following beneficial effects: 1. This utility model uses a synchronous drive component to drive multiple sets of distance adjustment components to work together, so that the storage tubes on each U-shaped plate can move synchronously in the direction of approaching or moving away from the central heater. The circular array of storage tubes can ensure that the distance between each set of storage tubes and the heater is consistent. At the same time, the drive unit can drive the first turntable, the second turntable and the storage tubes to rotate around the axis of the heater, so that each storage tube can receive the ring heat of the heater evenly. This completely avoids the drying difference of the same batch of tea leaves due to different distances from the heater, and significantly improves the drying uniformity of tea leaves.

[0014] 2. This utility model, through the structural design of an L-shaped plate, a second threaded rod, a lifting plate, an arc-shaped plate, and a rough ring at the left end of the storage cylinder, allows the storage cylinder to rotate as it rotates with the turntable. This utilizes the friction between the rough surface of the arc-shaped plate and the rough ring to drive the storage cylinder to rotate itself, causing the pomegranate leaf tea inside the storage cylinder to continuously tumble during drying. This effectively avoids the problem of incomplete drying in certain areas caused by the stacking of the tea leaves. At the same time, the ventilation hole design of the storage cylinder body further enhances the circulation of hot air, allowing the tea leaves to fully contact the hot air, significantly improving drying efficiency and the overall quality of the tea leaves.

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. Example 1

[0018] Please refer to Figures 1 to 6As shown, a drying device for preparing pomegranate leaf tea includes a U-shaped frame 1. A horizontally arranged rotating shaft 2 is rotatably connected to the right side plate of the U-shaped frame 1. A drive unit 3 connected to the rotating shaft 2 is arranged on the right side of the right side plate of the U-shaped frame 1. A coaxial first turntable 4 is fixedly connected to the left end of the rotating shaft 2. A fixing ring 5 coaxial with the first turntable 4 is fixedly connected to the right side of the left side plate of the U-shaped frame 1. A coaxial second turntable 6 is rotatably connected to the right end of the fixing ring 5. A mounting seat located inside the fixing ring 5 is also fixedly connected to the center of the right side of the left side plate of the U-shaped frame 1. A heater 7 is fixedly connected to the right end of the mounting base. A clearance hole 8 corresponding to the mounting base is opened in the center of the second turntable 6. Several distance adjustment components 9 are arranged in a circular array between the first turntable 4 and the second turntable 6. A synchronous drive component 10 connected to several distance adjustment components 9 is arranged on the right side of the first turntable 4. A U-shaped plate 11 is connected to each distance adjustment component 9. A storage tube 12 is arranged inside the U-shaped plate 11. The right end of the storage tube 12 is open and covered with a tube cover 13. Several ventilation holes are evenly distributed on the body of the storage tube 12.

[0019] Those skilled in the art will understand that, firstly, the pomegranate leaf tea to be dried is placed into the storage tube 12, and sealed by fitting a tube cover 13 over the open right end of the storage tube 12. The evenly distributed ventilation holes on the body of the storage tube 12 ensure the circulation of hot air. Then, the drive unit 3 is activated, which drives the rotating shaft 2 to rotate. The rotating shaft 2 further drives the first rotating disk 4, which is fixed coaxially, to rotate. The first rotating disk 4 drives the second rotating disk 6 to rotate synchronously around the fixed ring 5 through the distance adjustment component 9. This causes the U-shaped plates 11 and the storage tube 12, which are arranged in a ring array between the first rotating disk 4 and the second rotating disk 6, to rotate around the central axis of the heater 7. If it is necessary to adjust the distance between the storage tube 12 and the heater 7, multiple sets of distance adjustment components 9 can be driven by the synchronous drive component 10 to work together, so that the storage tube 12 can move in a direction closer to or further away from the heater 7, ensuring that the tea leaves in the storage tube 12 can receive the heat emitted by the heater 7 evenly. The circular array of storage cylinders 12 and the rotating turntable structure replace the fixed-spaced semi-circular storage plates in the comparative document, solving the problem of uneven drying of the same batch of tea leaves due to different distances from the heating source. At the same time, the cooperation between the distance adjustment component 9 and the synchronous drive component 10 can flexibly adjust the distance between the storage cylinders 12 and the heater 7 to adapt to the drying needs of different humidity levels and different quantities of tea leaves. Furthermore, the independent design of the storage cylinders 12 can avoid cross-contamination of tea leaves and improve operational convenience. Example 2

[0020] Furthermore, a first rectangular plug 14 is fixedly connected to the center of the left end of the storage tube 12. A first socket 15, which is compatible with the first rectangular plug 14, is rotatably connected to the right side of the left side plate of the U-shaped plate 11. A second rectangular plug 16 is fixedly connected to the center of the right side of the tube cover 13. A first threaded rod 17 is threadedly connected to the right side plate of the U-shaped plate 11. A mounting plate 18 is rotatably connected to the left end of the first threaded rod 17. A second socket 19, which is compatible with the second rectangular plug 16, is rotatably connected to the left side of the mounting plate 18. A first knob 20 is fixedly connected to the right end of the first threaded rod 17. Two first guide rods 21, which are symmetrically distributed on both sides of the first threaded rod 17, are fixedly connected to the right side of the mounting plate 18. Both first guide rods 21 are slidably connected to the right side plate of the U-shaped plate 11. A limit ring 22 is fixedly connected to the right end of both first guide rods 21.

[0021] Those skilled in the art will understand that when installing the storage tube 12, the first rectangular plug 14 at the left end of the storage tube 12 is first inserted into the first socket 15 to achieve positioning and rotational support of the left end of the storage tube 12; then the first knob 20 is rotated, which drives the first threaded rod 17 to rotate along the threaded hole on the right side plate of the U-shaped plate 11. The first threaded rod 17 pushes the mounting plate 18 to move to the left, and the second socket 19 on the left side of the mounting plate 18 then aligns with the second rectangular plug 16 on the right side of the tube cover 13 to complete the fixation of the right end of the storage tube 12; at the same time, the first guide rods 21 symmetrically distributed on the right side of the mounting plate 18 slide along the right side plate of the U-shaped plate 11 to ensure that the mounting plate 18 moves smoothly, and the limiting ring 22 can prevent the first guide rods 21 from slipping off the right side plate of the U-shaped plate 11. Example 3

[0022] Furthermore, the inner wall of the cylinder cover 13 is provided with a guide groove 23, and the outer wall of the right end opening of the storage cylinder 12 is fixedly connected with a guide slider 24 that is compatible with the guide groove 23.

[0023] Those skilled in the art will understand that when installing the cover 13, the operator needs to precisely align the guide slider 24 on the outer right side of the storage cylinder 12 with the guide groove 23 on the inner wall of the cover 13, and then push the cover 13 along the extension direction of the guide groove 23 until the cover 13 is completely fitted onto the open right side of the storage cylinder 12, thus completing the assembly of the two. During the operation of the device, when the storage cylinder 12 rotates around its own axis, the relative rotation between the storage cylinder 12 and the cover 13 is restricted by the limiting cooperation between the guide groove 23 and the guide slider 24, ensuring that the two always maintain a coaxial and synchronous rotation state. Example 4

[0024] Furthermore, an L-shaped plate 25 is fixedly connected to the right side of the left side plate of the U-shaped frame 1. The horizontal plate of the L-shaped plate 25 passes through the clearance hole 8, and the vertical plate of the L-shaped plate 25 is located to the right of the second turntable 6. A through groove 26 is opened on the vertical plate of the L-shaped plate 25. A vertically arranged second threaded rod 27 is rotatably connected in the through groove 26. The top end of the second threaded rod 27 extends to the top of the vertical plate of the L-shaped plate 25 and is fixedly connected to a second knob 28. A second guide rod 29 is also fixedly connected in the through groove 26. A lifting plate 30 is threadedly connected to the second threaded rod 27. The lifting plate 30 is slidably connected to the second guide rod 29. An arc-shaped plate 31 corresponding to the left end of the storage tube 12 is fixedly connected to the right end of the lifting plate 30. The outer arc surface of the top of the arc plate 31 is a rough surface. A rough ring 32 that cooperates with the arc plate 31 is fixedly connected to the left end of the storage tube 12.

[0025] Those skilled in the art will understand that when it is necessary to rotate the storage cylinder 12, the second knob 28 is turned, and the second knob 28 drives the second threaded rod 27 in the through groove 26 to rotate. The lifting plate 30 threaded on the second threaded rod 27 slides and rises along the second guide rod 29. The arc plate 31 at the right end of the lifting plate 30 rises accordingly until the rough surface at the top of the arc plate 31 is in contact with the rough ring 32 at the left end of the storage cylinder 12. At this time, the drive unit 3 drives the first turntable 4, the second turntable 6 and the storage cylinder 12 to rotate around the axis of the heater 7. The arc plate 31 is fixed, and the friction between its rough surface and the rough ring 32 drives the storage cylinder 12 to rotate around its own axis, thereby turning over the tea leaves in the storage cylinder 12. Example 5

[0026] Furthermore, the drive unit 3 includes a large pulley 301 fixedly connected to the right end of the rotating shaft 2, a motor 302 fixedly connected to the right side of the right side plate of the U-shaped frame 1 via a bracket, a small pulley 303 corresponding to the large pulley 301 fixedly connected to the output end of the motor 302, and a transmission belt 304 connecting the small pulley 303 and the large pulley 301.

[0027] Those skilled in the art will understand that when the motor 302 is started, its output drives the small pulley 303 to rotate. The small pulley 303 transmits power to the large pulley 301 on the right end of the rotating shaft 2 via the transmission belt 304. The large pulley 301 drives the rotating shaft 2 to rotate, thereby driving the first turntable 4, the second turntable 6, and the storage cylinder 12 to rotate as a whole. Simultaneously, the diameter difference between the large pulley 301 and the small pulley 303 enables speed reduction, ensuring the turntables and storage cylinder 12 maintain a suitable rotational speed, guaranteeing sufficient time for the tea leaves to receive heat and improving the drying effect. Example 6

[0028] Furthermore, the distance adjustment assembly 9 includes a double-ended threaded rod 901 rotatably connected between the first turntable 4 and the second turntable 6. Two third guide rods 902 symmetrically distributed on both sides of the double-ended threaded rod 901 are also fixedly connected between the first turntable 4 and the second turntable 6. Slide seats 903 are threadedly connected to the positive and negative threaded sections of the double-ended threaded rod 901. Both slide seats 903 are slidably connected to the two third guide rods 902. Push rods 904 are hinged to the side of the two slide seats 903 facing the axis of the first turntable 4. The other ends of the two push rods 904 are hinged to the side of the U-shaped plate 11 away from the axis of the first turntable 4.

[0029] Those skilled in the art will understand that when the synchronous drive assembly 10 drives the double-ended threaded rod 901 to rotate, the slide block 903 on the positive and negative threaded sections of the double-ended threaded rod 901 moves towards or away from each other along the two third guide rods 902; when the slide block 903 moves, it pushes or pulls the hinged push rod 904, and the push rod 904 drives the U-shaped plate 11 and the storage tube 12 to move in the direction of approaching or moving away from the heater 7, thereby realizing the adjustment of the distance between the storage tube 12 and the heater 7. Example 7

[0030] Furthermore, the synchronous drive assembly 10 includes a gear ring 1001 rotatably connected to the right side of the first turntable 4. The right end of the double-threaded rod 901 in each distance adjustment assembly 9 extends to the right side of the first turntable 4 and is fixedly connected to a gear 1002. Each gear 1002 meshes with the gear ring 1001. A plurality of fixed rods 1003 arranged in a ring array are fixedly connected to the right side of the gear ring 1001. The right ends of the plurality of fixed rods 1003 are jointly fixedly connected to a ring handle 1004.

[0031] Those skilled in the art will understand that rotating the annular handle 1004 causes the gear ring 1001 to rotate around the right side of the first turntable 4 via the fixed rod 1003. The gear ring 1001 meshes with the gear 1002 at the right end of the double-threaded rod 901 in each distance adjustment assembly 9, causing all gears 1002 and double-threaded rods 901 to rotate synchronously. This, in turn, causes multiple sets of distance adjustment assemblies 9 to synchronously adjust the distance between the corresponding U-shaped plates 11 and the storage tubes 12. The meshing transmission between the gear ring 1001 and the multiple sets of gears 1002 enables the synchronous operation of all distance adjustment assemblies 9, ensuring that the distance between all storage tubes 12 and the heater 7 remains consistent.

[0032] In this embodiment, the heater 7 and motor 302 used in this application are both existing technologies, and the connections between the components are also existing technologies. Therefore, their connection relationships and principles will not be described in detail here. In addition, the double-threaded rod 901, gear ring 1002, gear 1003, first threaded rod 17 and second threaded rod 27 and other transmission components are all equipped with protective components by default to ensure the stable operation of the transmission components. These protective components are all existing technologies, so they will not be described in detail here.

[0033] Working principle and usage procedure of this device: S1. First, fill the tea leaves and install the storage tube: put the pomegranate tea leaves to be dried into the open end of the storage tube 12 from the right end, then align the guide slider 24 at the right end of the storage tube 12 with the guide groove 23 on the inner wall of the tube cover 13, and push the tube cover 13 to complete the seal. S2. Next, insert the first rectangular plug 14 at the left end of the storage tube 12 into the first socket 15 on the right side of the left side plate of the U-shaped plate 11. Turn the first knob 20 to drive the first threaded rod 17 to rotate. The first threaded rod 17 pushes the mounting plate 18 to the left, so that the second socket 19 on the left side of the mounting plate 18 aligns with the second rectangular plug 16 on the right side of the tube cover 13, thus completing the fixing of the storage tube 12 in the U-shaped plate 11. S3. Then adjust the distance between the storage tube and the heater: rotate the ring handle 1004. The ring handle 1004 drives the gear ring 1001 to rotate through the fixed rod 1003. The gear ring 1001 meshes with each gear 1002, driving the double-threaded rods 901 of all distance adjustment components 9 to rotate synchronously. The slide 903 on the double-threaded rod 901 moves towards or away from each other along the third guide rod 902, pushing the push rod 904 to drive the U-shaped plate 11 and the storage tube 12 to move synchronously until the distance between the storage tube 12 and the heater 7 on the left side plate mounting seat of the U-shaped frame 1 reaches the preset requirement. S4. Then start the drying and rotation function: Start the motor 302, the motor 302 drives the small pulley 303 to rotate, the small pulley 303 drives the large pulley 301 and the rotating shaft 2 to rotate through the transmission belt 304, the rotating shaft 2 drives the first turntable 4 to rotate, the first turntable 4 drives the second turntable 6 to rotate synchronously around the fixed ring 5 through the distance adjustment component 9, so that the entire storage cylinder 12 rotates around the axis of the heater 7; at the same time, turn the second knob 28, the second knob 28 drives the second threaded rod 27 to rotate, the lifting plate 30 rises along the second guide rod 29, so that the rough surface of the right end arc plate 31 of the lifting plate 30 is in contact with the rough ring 32 at the left end of the storage cylinder 12, and the friction force drives the storage cylinder 12 to rotate. The ventilation holes in the body of the storage cylinder 12 ensure the circulation of hot air, so as to realize the turning of the tea leaves and uniform drying.
