[0003] A specific example of the pressurizing mechanism in an existing tea rolling machine can be found in application number CN202222860533.X, which includes a rolling drum, a rolling disc, a pressure plate, and a tea receiving container. The rolling disc includes a base and a disassembly disc. The disassembly disc is movably mounted on the base. Ribs are provided on the surface of the disassembly disc. A heating mechanism is provided inside the base. The beneficial effects of this utility model are: it solves the problems that since most rolling discs are fixed on a support frame, it is inconvenient to disassemble and install the rolling disc as a whole, and the rolling discs on the frame have a convex rib structure, which requires a lot of time, manpower, and material resources for cleaning and maintenance. The aforementioned device does not have a component for pressure protection. When pressing down on the tea leaves, it is impossible to effectively control the force. If the force is too great, the tea leaves are easily crushed, thereby reducing the pass rate and increasing the loss. Therefore, a pressure mechanism for a tea rolling machine is proposed to address the above problems. Utility Model Content

One end of the return spring 13 is fixedly connected to the moving block 12, and the other end of the return spring 13 is fixedly connected to the fixed guide seat 10. During operation, the movable block 12 moves along the outside of the fixed guide rod 11 inside the fixed guide seat 10. At the same time, when the movable block 12 moves, it will pull the return spring 13 to extend, thereby relieving the greater pressure and protecting the tea leaves.

[0017] Furthermore, the top end of the movable block 12 is fixedly connected to the bottom end of the first fixed seat 14, and the bottom end of the rotating push rod 15 is sleeved on the outer side of the top end of the first fixed seat 14. The rotating push rod 15 is rotatably connected to the first fixed seat 14, and the inner wall of the rotating push rod 15 sleeved on the outer side of the first fixed seat 14 is designed to be circular. When the push rod 15 is rotated during operation, it will simultaneously rotate along the outer side of the first fixed seat 14 and apply an outward thrust to the first fixed seat 14.

[0018] Furthermore, a lower pressure plate 17 is provided above the pressure plate 2, and four sets of second fixed seats 16 are provided at the bottom of the lower pressure plate 17. The bottom of the lower pressure plate 17 is fixedly connected to the top of the second fixed seat 16. The top of the rotating push rod 15 is sleeved on the outer side of the bottom of the second fixed seat 16, and the rotating push rod 15 is rotatably connected to the second fixed seat 16. The inner wall of the rotating push rod 15 sleeved on the outer side of the second fixed seat 16 is designed to be circular. During operation, the pressure will be transmitted to the second fixed seat 16 at the bottom of the lower pressure plate 17 and the rotating push rod 15, causing the top of the rotating push rod 15 to rotate along the outside of the second fixed seat 16.

[0019] Furthermore, the top of the lower pressure plate 17 is fixedly connected to the bottom of the first fixed sleeve block 18. The first fixed sleeve block 18 is sleeved inside the outer side of the bottom of the threaded rod 19, and the threaded rod 19 is rotatably connected to the first fixed sleeve block 18. The top of the threaded rod 19 is fixedly connected to the bottom of the rotating disk 20. The inner wall of the first fixed sleeve block 18 is circular. During operation, the rotating disk 20 is rotated. When the rotating disk 20 rotates, it will drive the threaded rod 19 to rotate synchronously. At the same time, the bottom end of the threaded rod 19 will rotate along the inside of the first fixed sleeve block 18 at the top of the lower pressure plate 17.

[0020] Furthermore, a fixing frame 21 is sleeved on the outer side of the threaded rod 19, and the threaded rod 19 is threadedly connected to the fixing frame 21. The bottom end of the fixing frame 21 is fixedly connected to the top end of the rotating rod 22. A second fixing block 23 is sleeved on the outer side of the bottom end of the rotating rod 22, and the rotating rod 22 is rotatably connected to the second fixing block 23. The bottom end of the second fixing block 23 is fixedly connected to the top end of the base plate 24. The inner wall of the second fixing block 23 is circular. The side end of the base plate 24 is fixedly connected to the outer side of the kneading barrel 1. During operation, tea leaves are placed inside the kneading barrel 1, and the fixing frame 21 is rotated. When the fixing frame 21 rotates, it will drive the bottom end of the rotating rod 22 to rotate along the inside of the second fixing sleeve block 23 at the top of the base plate 24 until the pressure plate 2 rotates above the kneading barrel 1. The threaded rod 19 rotates, and as the threaded rod 19 rotates along the inside of the fixing frame 21, it will gradually move downwards.

[0021] Furthermore, the inner wall of the kneading drum 1 is provided with three sets of observation windows 25, the inner wall of the kneading drum 1 is fixedly connected to the outer side of the observation windows 25, and the observation windows 25 are designed with transparent plastic material. During operation, staff can check the pressure through the observation window 25 to prevent excessive pressure from affecting the tea leaves.

[0022] Working principle: When pressing is required, first place tea leaves inside the kneading drum 1, then rotate the fixing frame 21. As the fixing frame 21 rotates, it will cause the bottom end of the rotating rod 22 to rotate along the inside of the second fixing sleeve 23 at the top of the base plate 24 until the pressing plate 2 rotates above the kneading drum 1. Then rotate the rotating disk 20. When the rotating disk 20 rotates, it will cause the threaded rod 19 to rotate synchronously. Simultaneously, as the threaded rod 19 rotates, its bottom end will rotate along the inside of the first fixing sleeve 18 at the top of the lower pressing plate 17. During this rotation along the fixing frame 21, the threaded rod 19 will gradually move downwards, pushing the lower pressing plate 17 downwards. When the lower pressing plate 17 moves downwards, it will... The pressure plate 2 moves downwards until the tea leaves are compressed. However, if the pressure is too high, it will be transmitted to the second fixed seat 16 and the rotating push rod 15, causing the top of the rotating push rod 15 to rotate along the outside of the second fixed seat 16. At the same time, as the rotating push rod 15 rotates, it will also rotate along the outside of the first fixed seat 14, applying an outward pushing force to the first fixed seat 14 and causing it to move outwards. When the first fixed seat 14 moves outwards, it will cause the moving block 12 to move along the outside of the fixed guide rod 11 inside the fixed guide seat 10. At the same time, when the moving block 12 moves, it will pull the return spring 13 to extend, thereby relieving the excessive pressure and protecting the tea leaves. Meanwhile, the staff can check the pressing situation through the observation window 25 to prevent excessive pressure from affecting the tea leaves.
