[0002] With the continuous development of modern technology, the production field of tea has made great progress. During the tea production and processing process, flattening is a relatively important process.

[0003] The Chinese patent discloses a tea flattening device for tea processing, with the publication number CN218681718U. It is proposed in the text that "it includes a flattening box and a quantitative component. Brackets are fixedly installed on both sides of the flattening box and are symmetrically distributed. The adjacent side walls of the two brackets are fixedly installed with a conveying box. The quantitative component is arranged inside the conveying box. The quantitative component includes a rotating column, a sleeve seat and a partition plate. By driving the sleeve seat to rotate through the rotating column, the cavities formed by the conveying box and the partition plate are used to hold tea in sequence, and the rotation of the rotating column is used to put the tea, so as to quantitatively convey the tea"; this flattening device sends the tea to the inside of the flattening box for flattening operation. Since there is only one space inside the flattening box, only one piece of tea can be fed and flattened at a time, and the next portion of tea can be flattened only after the complete discharge, and continuous batch flattening treatment cannot be carried out, reducing the working efficiency of the overall device for flattening tea. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tea flattening device, which solves the problem in the related technology that continuous batch flattening treatment cannot be carried out during use, reducing the working efficiency of the overall device for flattening tea.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3, this embodiment proposes a flattening device for tea leaves, including an outer frame 1. A sealing plate 2 for sealing is fixedly installed at the bottom end of the outer frame 1. The top end of the sealing plate 2 is rotatably connected to an outer ring 3. A plurality of tea columns 31 for flattening tea leaves are fixedly installed on the inner side wall of the outer ring 3. An inner column 32 is fixedly installed on the inner side wall of the tea column 31. The bottom ends of the inner columns 32 are respectively rotatably connected to the sealing plate 2 and the inner wall of the outer frame 1. A discharge port 21 for discharging materials is provided on the inner side wall of the sealing plate 2. A plurality of flattening components 4 for flattening tea leaves are arranged on the outer side of the inner column 32. A driving component 5 for driving the flattening components 4 is arranged at the top end of the outer frame 1. A driving motor 11 is fixedly installed at the bottom end of the outer frame 1. The output end of the driving motor 11 is fixedly connected to the bottom end of the inner column 32. A limiting ring 12 is fixedly installed on the outer side of the outer frame 1. The inner side wall of the limiting ring 12 is rotatably connected to the outer side of the outer ring 3. A support column 13 is fixedly installed on the outer side of the limiting ring 12. A feeding funnel 14 is fixedly installed at the top end of the support column 13. When using this device to flatten tea leaves, tea leaves can be added into the tea column 31 below it through the feeding funnel 14. The driving motor 11 drives the inner column 32 to rotate inside the outer frame 1, so as to drive the tea column 31 and the outer ring 3 to rotate on the inner wall of the limiting ring 12, and at the same time drive the flattening components 4 to rotate synchronously through the inner column 32, so that the flattening components 4 can flatten the tea leaves inside the tea column 31 below it. When the tea column 31 rotates to the position of the discharge port 21 of the sealing plate 2 following the inner column 32, the flattened tea leaves inside the tea column 31 can be discharged from the discharge port 21. When the empty tea column 31 continues to rotate, the driving component 5 acts on the flattening components 4 to extract them from the inside of the tea column 31, so that when the tea column 31 moves to the position of the feeding funnel 14, tea leaves can be continuously added into the tea column 31, maintaining the continuity of the overall flattening operation of the tea leaves by the flattening device;

[0025] Please refer to Figure 3 , Figure 4 and Figure 5, in this embodiment, a flattening device for tea leaves is proposed. The flattening assembly 4 includes multiple ejector rods 41 fixedly installed on the outer side of the top of the inner column 32. A plurality of bottom rods 42 are also fixedly installed on the outer side of the inner column 32. The flattening assembly 4 further includes a driving lead screw 43 rotatably connected to the inner side wall of the ejector rod 41. A flattening column 44 is slidably connected to the inner side wall of the bottom rod 42. The inner wall of the top end of the flattening column 44 is threadedly connected to the outer side of the bottom end of the driving lead screw 43. The driving assembly 5 includes a top plate 51 fixedly installed on the inner wall of the top of the outer frame 1. A half gear 52 and a half tooth ring 53 are respectively fixedly installed at the bottom of the top plate 51. The driving assembly 5 includes a driving gear 54 fixedly installed at the top end of the driving lead screw 43. The driving gear 54 meshes with the half gear 52 and the half tooth ring 53 respectively. While the inner column 32 drives the ejector rod 41 and the bottom rod 42 to rotate, it can drive the flattening column 44 and the driving lead screw 43 on it to move synchronously. Thus, the driving lead screw 43 can rotate inside the flattening column 44 through the contact between the driving gear 54 and the half gear 52 or the half tooth ring 53, so as to drive the flattening column 44 to move up and down and slide, and flatten the tea leaves inside the tea column 31.

[0026] In this embodiment, during use, the driving lead screw 43 and the flattening column 44 are synchronously driven to rotate on the inner wall of the outer frame 1 by multiple tea columns 31, so that the feeding hopper 14 can continuously add the tea leaves to be flattened into the tea column 31. During the rotation of the tea column 31, through the interaction between the driving gear 54 on the driving lead screw 43 and the half tooth ring 53 or the half gear 52, the flattening column 44 can gradually press down into the tea column 31 to flatten the tea leaves inside it. Then, the flattened tea leaves are discharged downward to the discharge port 21 on the sealing plate 2. Thus, the tea leaves can be continuously flattened and the feeding and discharging operations can be carried out continuously during the continuous rotation of the tea column 31, improving the working efficiency of the overall device for flattening the tea leaves.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
