There are many types of tea, which can be divided into six categories according to factors such as fermentation degree and preparation method: green tea, black tea, yellow tea, oolong tea, dark tea and white tea. Flattening is one of the links in tea processing. After searching, the Chinese patent authorization number CN220494141U discloses a flattening device for tea processing, which belongs to the field of tea processing technology, including a supporting mechanism for placing tea leaves; a flattening mechanism capable of flattening the tea leaves on the supporting mechanism is provided above the supporting mechanism; the flattening mechanism is supported by a Two parallel fixed bars are provided on one side near the supporting mechanism; a slide groove is opened on each fixed bar; a slider is slidably arranged in each slide groove; a scraper is connected between the two sliders; in the present application, the scraper is driven to move by the slider, so that the tea leaves adhering to the flattening mechanism after being flattened can be scraped off, thereby avoiding the tea leaves remaining on the flattening mechanism from being mixed with the new tea leaves when the next batch of tea leaves is flattened, thereby reducing the impurity content of the tea leaves and improving the purity of the tea leaves; at the same time, after the tea leaves remaining on the flattening mechanism are scraped off, the situation of cross-flavoring of two different tea leaves can be avoided, thereby ensuring the quality of the tea leaves.

[0003] The flattening device for tea processing in the above patent has the following shortcomings: when the device is in use, the user needs to pull the outer end of the support plate after each flattening of the tea leaves to separate the support plate from the discharge pipe so that the tea leaves can be unloaded from the discharge pipe. This requires the user to perform repeated operations, which increases the user's workload. For this reason, a flattening device for tea leaves is designed. Utility Model Content

The extrusion bin 6 is provided with a sliding groove that is compatible with the L-shaped sliding plate 18. The L-shaped sliding plate 18 is located on the outside of the extrusion bin 6 and is fixedly connected to a connecting rod 22. The other end of the connecting rod 22 is fixedly connected to a triangular plate 23. A groove that is compatible with the triangular plate 23 is provided in the middle of the top of the L-shaped connecting plate 19.

[0022] In this embodiment, a discharge pipe 12 is fixedly connected to the bottom of the extrusion bin 6 , and a feed hopper 7 is fixedly connected to the top of the extrusion bin 6 .

[0023] In this embodiment, a same sliding rod 13 is fixedly connected between the two sides of the inner wall of the feed hopper 7 near the front end, and a screw block 16 is slidably sleeved on the circumferential surface of the sliding rod 13. A cleaning brush 17 is fixedly connected to the rear side of the screw block 16. A screw rod 14 is rotatably connected between the two sides of the inner wall of the front end of the feed hopper 7, and the screw rod 14 threadedly penetrates the screw block 16. A threaded hole matching the screw rod 14 is opened on the screw block 16. A motor 15 is fixedly connected to one end of the outer side of the feed hopper 7, and the output end of the motor 15 penetrates the feed hopper 7 and is fixedly connected to one end of the screw rod 14. Through the forward and reverse rotation of the motor 15, the cleaning brush 17 can clean the bottom of the L-shaped pressure plate 11.

[0024] In this embodiment, a bracket 2 is fixedly connected to the top of the bottom plate 1 , a hydraulic push rod 3 is fixedly connected to the inner side of the top of the bracket 2 , and a lifting plate 4 is fixedly connected to the bottom of the hydraulic push rod 3 .

[0025] In this embodiment, an L-shaped rod 8 is fixedly connected to the rear end of the bottom of the lifting plate 4, and a rotating block 24 is rotatably connected to the bottom bending part of the L-shaped rod 8, and the rotating block 24 is adapted to the triangular plate 23. The cooperation between the rotating block 24 and the triangular plate 23 enables the L-shaped sliding plate 18 to separate from the extrusion chamber 6 when the hydraulic push rod 3 contracts.

[0026] In this embodiment, a connecting rod 10 is fixedly connected to the front end of the bottom of the lifting plate 4, and an L-shaped pressing plate 11 is fixedly connected to the bottom of the connecting rod 10. The L-shaped pressing plate 11 is adapted to the inner wall of the extrusion bin 6, and an electric heating wire is arranged inside the L-shaped pressing plate 11. The arrangement of the electric heating wire facilitates the shaping of the tea leaves.

[0027] Working principle: A tea flattening device. When in use, the tea is put into the extrusion bin 6 through the feed hopper 7, and the hydraulic push rod 3 is started to extend, so that the lifting plate 4 with the connecting rod 10 and the L-shaped pressing plate 11 descends, and the electric heating wire inside the L-shaped pressing plate 11 is turned on at the same time. The L-shaped pressing plate 11 descends and cooperates with the extrusion bin 6 and the L-shaped sliding plate 18 to achieve the flattening of the tea leaves. The electric heating wire is convenient for shaping the tea leaves. When the flattening operation is completed, the hydraulic push rod 3 is started to shrink, so that the L-shaped pressing plate 11 is separated from the L-shaped sliding plate 18. When it is necessary to clean the bottom of the L-shaped pressing plate 11, when the L-shaped pressing plate 11 returns to the highest point, the motor 15 is started, so that the screw rod 14 moves with the screw block 16 and the cleaning brush 17 to achieve the bottom of the L-shaped pressing plate 11. The attached tea leaves are cleaned, and the motor 15 is controlled by the PLC controller. When the hydraulic push rod 3 extends and brings the L-shaped pressing plate 11 down, the rotating block 24 rotates when it contacts the triangular plate 23. When the L-shaped pressing plate 11 drops to the lowest point, the rotating block 24 reaches the bottom of the triangular plate 23. When the hydraulic push rod 3 contracts, the rotating block 24 becomes horizontal. At this time, the rotating block 24 is stuck with the hypotenuse of the triangular plate 23, driving the triangular plate 23 and the L-shaped sliding plate 18 to push back. At this time, the L-shaped sliding plate 18 will gradually slide out of the extrusion bin 6, so that the pressed tea leaves descend through the discharge pipe 12. When the rotating block 24 is completely separated from the triangular plate 23, under the action of the spring 21, the L-shaped sliding plate 18 is reset, and the user can add tea leaves again.
