Technical Field
[0001] This utility model relates to the field of sieve plate technology, and in particular to a sieve plate for a black tea fermentation machine. Background Technology
[0002] Fermentation is a crucial step in black tea processing, directly impacting the tea's color, aroma, and flavor. To achieve efficient and uniform fermentation, black tea fermentation machines are widely used in modern black tea production. Among these machines, the sieve plate, a vital component, plays a key role in controlling the fermentation environment, regulating aeration, and ensuring even distribution of tea leaves.
[0003] However, the existing sieve plates of black tea fermentation machines still have certain defects. For example, the sieve hole diameter cannot be adjusted, which means that when it is necessary to change the air permeability, the sieve plate inside the black tea fermentation machine can only be replaced, which is inconvenient and lacks practicality. Utility Model Content

It can precisely adjust the size of the sieve holes formed between the first and second through holes, thereby effectively controlling the air permeability during the black tea fermentation process, thus providing the best fermentation environment for black tea and improving the fermentation quality. When the first or second sieve plate is damaged, only the corresponding sieve plate needs to be replaced, without replacing the whole machine, which is highly practical.
[0005] This utility model also provides a sieve plate for a black tea fermentation machine as described above, comprising:
[0006] A first sieve plate has a first through hole on its outer surface. A fixing plate is fixedly connected to the lower surface of the first sieve plate.

[0009] According to the aforementioned sieve plate for a black tea fermentation machine, the inner surface of the slot is provided with a groove, the inner surface of which is adapted to an L-shaped buckle block, facilitating the overall installation of the second sieve plate.
[0010] According to the aforementioned black tea fermentation machine sieve plate, the upper surface of the first sieve plate is fixedly connected with four fixing buckles arranged in a rectangular array, which facilitates the installation of the entire sieve plate inside the fermentation machine.
[0011] According to the aforementioned sieve plate of a black tea fermentation machine, the lower surface of the first sieve plate is in contact with the second sieve plate, and the first through hole corresponds to the second through hole, which facilitates the air permeability of the black tea.
[0012] According to the aforementioned sieve plate of a black tea fermentation machine, the right end of the first spring is fixedly connected to a fixed plate, and the left end of the first spring is fixedly connected to a second sieve plate.
[0013] According to the aforementioned sieve plate of a black tea fermentation machine, the left surface of the second sieve plate is in contact with an adjusting nut, which facilitates the adjustment of the size of the sieve holes.
[0014] According to the sieve plate of the black tea fermentation machine, both ends of the second spring are fixedly connected to the L-shaped buckle block.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1.

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0027] Reference Figure 1-4 This utility model discloses a sieve plate for a black tea fermentation machine, comprising: a first sieve plate 1, a first through hole 2 on the outer surface of the first sieve plate 1, a fixing plate 3 fixedly connected to the lower surface of the first sieve plate 1, a guide rod 4 fixedly connected to the side surface of the fixing plate 3, a second sieve plate 5 slidably connected to the outer surface of the guide rod 4, a second through hole 6 on the outer surface of the second sieve plate 5, a first spring 7 on the outer surface of the guide rod 4, an adjusting nut 8 threadedly connected to the outer surface of the guide rod 4, a scale 9 on the lower surface of the first sieve plate 1, a slot 15 on the lower surface of the first sieve plate 1, a groove 16 on the inner surface of the slot 15, and four fixing buckles 17 fixedly connected to the upper surface of the first sieve plate 1 in a rectangular array. The lower surface of the first sieve plate 1 is in contact with the second sieve plate 5, the first through hole 2 corresponds to the second through hole 6, the right end of the first spring 7 is fixedly connected to the fixing plate 3, the left end of the first spring 7 is fixedly connected to the second sieve plate 5, and the left surface of the second sieve plate 5 is in contact with the adjusting nut 8.
[0028] The lower surface of the fixed plate 3 is provided with a limiting groove 10. The limiting groove 10 is used to limit the movement of the L-shaped buckle block 13. The inner surface of the limiting groove 10 is fixedly connected to a slide rod 11. The outer surface of the slide rod 11 is provided with a second spring 12. The outer surface of the slide rod 11 is slidably connected to the L-shaped buckle block 13. The outer surface of the L-shaped buckle block 13 is provided with a rubber sleeve 14. The rubber sleeve 14 can improve the comfort when pressing the L-shaped buckle block 13. The inner surface of the slot 15 is adapted to the L-shaped buckle block 13. The inner surface of the slot 16 is adapted to the L-shaped buckle block 13. Both ends of the second spring 12 are fixedly connected to the L-shaped buckle block 13.
[0029] Working principle: During use, according to the required air permeability, rotate the adjusting nut 8 on the guide rod 4 to drive the second sieve plate 5 to slide along the guide rod 4, and compress the first spring 7. This will cause the first through hole 2 on the first sieve plate 1 and the second through hole 6 on the second sieve plate 5 to be misaligned. At the same time, according to the scale 9, the size of the sieve holes can be precisely adjusted to meet the air permeability requirements of black tea and improve the fermentation effect. When either the first sieve plate 1 or the second sieve plate 5 is damaged, simply press the corresponding two rubber sleeves 14 along the inside of the limiting groove 10 to drive the corresponding two L-shaped latch blocks 13 to slide towards each other along the slide rod 11, thus activating the L-shaped latch blocks 13. By disengaging from the inside of the slot 16, the restrictive effect of the first screen plate 1 and the second screen plate 5 as a whole is released. Then, the first screen plate 1 or the second screen plate 5 as a whole is pulled out along the inside of the slot 15, thus completing the disassembly of the first screen plate 1 or the second screen plate 5 as a whole. When installing a new first screen plate 1 or the second screen plate 5 as a whole, simply insert the L-shaped buckle block 13, which is in a state of opposite compression, into the slot 15. When the L-shaped buckle block 13 corresponds to the slot 16, release the rubber sleeve 14. Under the action of the rebound force of the second spring 12, the two corresponding L-shaped buckle blocks 13 will be driven into the corresponding slots 16, thus completing the installation of the first screen plate 1 and the second screen plate 5 as a whole. It is simple and convenient.
[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
