Description

Technical Field

[0001] This invention relates to the field of tea production technology, specifically a tea pressing device. Background Technology

[0002] Tea originated in China, initially used as a sacrificial offering. However, from the late Spring and Autumn Period, it was consumed as a vegetable, developed medicinal uses in the mid-Western Han Dynasty, and became a high-class beverage in the imperial court in the late Western Han Dynasty. Its widespread use as a common beverage among the common people only began after the Western Jin Dynasty. The earliest evidence of artificial tea cultivation has been found at the Tianluoshan site in Yuyao, Zhejiang Province, dating back over 6,000 years. Tea drinking originated in China. The leaves are leathery, oblong or elliptical, and can be steeped directly in boiling water. Based on variety, processing method, and product appearance, tea is classified into six main categories. Based on seasonal harvesting, it can be divided into spring tea, summer tea, autumn tea, and winter tea. Various raw or refined tea leaves are further processed to create additional teas, including flower tea, compressed tea, extracted tea, medicinal and health teas, tea-based foods, and tea-containing beverages.

[0003] Existing tea bricks require pressing devices for compaction, but existing pressing devices have limited functionality and offer little protection or assistance for air hammers, failing to meet usage requirements. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a tea pressing device.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: A tea pressing device includes a body, a shielding component, a receiving component, and a limiting component. The body is provided with the shielding component, the receiving component, and the limiting component. The body includes an air hammer that drives the pressing plate to work. The air hammer has openings on both sides, and the openings are provided with shielding components. The air hammer drives the pressing plate to move toward the inside of the receiving component through a connecting rod. A foot pedal is installed on the side of the body near the receiving component. The foot pedal is connected to the air hammer, and a limiting component is installed on the side of the foot pedal.

[0006] Preferably, the limiting component includes a fixed plate, a movable block, a follower rod, and a limiting rod. The fixed plate is installed at one end of the machine body by a threaded bolt. Two spaced clamping strips are installed on the side of the fixed plate flush with the machine body. The interior of each clamping strip is hollow and has a horizontally opened movable groove. A movable block is slidably installed inside the movable groove. A transmission rod is installed in the middle of the movable block between the two clamping strips. One end of the transmission rod is fixedly connected to the movable block, and the other end is fixedly connected to the horizontally positioned L-shaped follower rod. One end of the follower rod extends toward the bottom of the foot pedal, and a grid plate is installed at the other end. A limiting rod is fixedly installed on the upper surface of the follower rod on one side of the bottom of the foot pedal. The limiting rod is vertically positioned and abuts against the bottom end of the foot pedal.

[0007] Preferably, an inner rod is horizontally fixedly installed inside the movable groove relative to the direction of the limiting rod. The inner rod is inserted into the outer rod and is hollow with a spring inside that is connected to the inner rod. The other end of the outer rod is fixedly connected to a movable block.

[0008] Preferably, the receiving assembly includes a collection box fixedly installed on the machine body. The bottom of the collection box is provided with a movable and liftable base plate. The bottom end face of the base plate is connected to a vertically arranged threaded rod. A driven gear is also sleeved on the outside of the threaded rod. The driven gear is hollow inside and has an internal thread on its inner wall that matches the threaded rod. A gear plate is also provided on the side of the driven gear. The gear plate meshes with the driven gear. The gear plate is connected to a drive motor fixedly installed inside the machine body through a connecting shaft.

[0009] Preferably, a groove for inserting a limiting post is provided at the inner center of the threaded rod. The limiting post is vertically fixedly installed at the bottom of the threaded rod and inserted into the bottom of the threaded rod. A lifting block is protruding from the upper side wall of the limiting post. The lifting block is embedded in the lifting groove vertically opened on the inner wall of the threaded rod and slides vertically along the lifting groove.

[0010] Preferably, the shielding assembly includes mounting frames symmetrically installed on both sides of the machine body and mounting tubes fixedly installed on the inner wall of the machine body. The mounting tubes are installed separately from the air hammers inside the machine body and do not contact each other. Two parallel telescopic cylinders are installed inside the mounting tubes, and the mounting tubes have holes on the surfaces facing the two mounting frames for the telescopic cylinders to extend out. The telescopic cylinders are slidably connected to the surface of the first swing plate facing the air hammers.

[0011] Preferably, the mounting frame has a first swing plate and a second swing plate hinged to each other inside. The second swing plate is located below the first swing plate. A locking block protrudes from the surface of the second swing plate facing the first swing plate when it is flipped and folded up. A fitting groove adapted to the locking block is opened on the first swing plate.

[0012] Preferably, the machine body is further provided with a lifting plate, which is fixedly connected to the air hammer through a connector. The connector passes through a movable slot vertically opened on the machine body, and the lifting plate is connected to a connecting rod for transmission.

[0013] The beneficial effects of this invention are as follows: The tea pressing device described in this invention can effectively increase the safety of the device through the setting of the shielding component. Furthermore, when maintenance of the air hammer drive system is required, the bending and folding of the second and first swing plates effectively improves the convenience of maintenance. When the second and first swing plates are unfolded, they can effectively shield the drive part of the air hammer, ensuring strong safety. The limiting component can slide away when tea pressing is needed, or limit the foot pedal otherwise, further improving the safety of the device during operation and preventing accidental stepping or impact from falling objects that could cause automatic operation, thus reducing safety hazards. The material receiving component can adjust the position of the pressed tea bricks upwards, bringing them closer to the opening of the collection box for easier removal. This tea pressing device increases the efficiency of tea pressing, improves ease of use, and can be widely promoted. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, a tea pressing device of the present invention includes a body 2, a shielding component 1, a receiving component 7, and a limiting component 9. The body 2 is provided with the shielding component 1, the receiving component 7, and the limiting component 9. The body 2 includes an air hammer that drives the pressing plate to work. The air hammer has openings on both sides, and the shielding component 1 is provided at the opening. The air hammer drives the pressing plate to move toward the inside of the receiving component 7 through a connecting rod 6. A foot pedal 8 is installed on the side of the body 2 near the receiving component 7. The foot pedal 8 is connected to the air hammer, and the limiting component 9 is installed on the side of the foot pedal 8. The body 2 is also provided with a lifting plate 4. The lifting plate 4 is fixedly connected to the air hammer through a connecting member. The connecting member passes through a vertically opened movable slot 5 on the body 2. The lifting plate 4 is connected to the connecting rod 6 for transmission.

[0023] The shielding assembly 1 includes mounting frames 3 symmetrically installed on both sides of the body 2 and mounting tubes 30 fixedly installed on the inner wall of the body 2. The mounting tubes 30 are staggered from the air hammers inside the body 2 and do not contact each other. Two parallel telescopic cylinders 35 are installed inside the mounting tubes 30, and each surface of the mounting tube 30 facing the two mounting frames 3 has holes for the telescopic ends of the cylinders 35 to extend. The telescopic cylinders 35 are slidably connected to the surface of the first swing plate 32 facing the air hammers. The cylinders extend through the two telescopic cylinders 35 in different directions, carrying... The first swing plate 32 is flipped open. Inside the mounting frame 3, there are a first swing plate 32 and a second swing plate 33 that are hinged to each other. The second swing plate 33 is located below the first swing plate 32. A locking block 34 protrudes from the surface of the second swing plate 33 facing the first swing plate 32 when it is flipped and folded up. The first swing plate 32 has a fitting groove 31 that matches the locking block 34. The locking block 34 extends into the fitting groove 31 to lock and store the first swing plate 32 and the second swing plate 33. The air hammer is exposed and can be inspected and maintained.

[0024] The limiting assembly 9 includes a fixed plate, a movable block 12, a follower rod 20, and a limiting rod 13. The fixed plate is installed at one end of the body 2 by a threaded bolt. Two spaced clamping bars 11 are installed on the side of the fixed plate flush with the body 2. The interior of the clamping bars 11 is hollow and has a horizontally opened movable groove 17. A movable block 12 is slidably installed inside the movable groove 17. A transmission rod 15 is installed in the middle of the movable block 12 between the two clamping bars 11. One end of the transmission rod 15 is fixedly connected to the movable block 12, and the other end is fixedly connected to the horizontally positioned L-shaped follower rod 20. One end of the follower rod 20 extends toward the bottom of the foot pedal 8, and the other end is equipped with a grid plate 14. The follower rod 20 is located on one side of the bottom of the foot pedal 8. A limiting rod 13 is fixedly installed on the upper surface. The limiting rod 13 is vertically set and abuts against the bottom end of the foot pedal 8. The limiting component 9 protects the foot pedal 8 and prevents it from being impacted by falling objects and operating automatically, thus reducing safety hazards. An inner rod 18 is fixedly installed horizontally inside the moving groove 17 relative to the direction of the limiting rod 13. The inner rod 18 is inserted into the outer rod 19. The outer rod 19 is hollow and has a spring 16 connected to the inner rod 18 inside. The other end of the outer rod 19 is fixedly connected to the moving block 12. The follower rod 20 drives the moving block 12 located inside the moving groove 17 to slide through the transmission rod 15. During the movement, the moving block 12 drives the outer rod 19 to move towards the inner rod 18, thereby causing the spring 16 to contract.

[0025] The material receiving assembly 7 includes a collection box 22 fixedly installed on the machine body 2. The bottom of the collection box 22 has a movable and liftable base plate 21. The bottom end of the base plate 21 is connected to a vertically arranged threaded rod 23. A driven gear 24 is also sleeved on the outside of the threaded rod 23. The driven gear 24 is hollow inside and has internal threads on its inner wall that are compatible with the threaded rod 23. A gear disc 27 is also provided beside the driven gear 24. The gear disc 27 meshes with the driven gear 24. The gear disc 27 is connected to a drive motor 26 fixedly installed inside the machine body 2 via a connecting shaft. The drive motor 26 drives the gear disc 27 to rotate. 7 meshes with the driven gear 24 to drive its rotation. A groove for inserting the limiting post 25 is provided at the inner center of the threaded rod 23. The limiting post 25 is vertically fixed at the bottom of the threaded rod 23 and is inserted into the bottom of the threaded rod 23. A lifting block 28 protrudes from the upper side wall of the limiting post 25. The lifting block 28 is embedded in the lifting groove 29 vertically opened on the inner wall of the threaded rod 23 and slides vertically along the lifting groove 29. The limiting post 25 is provided at the bottom of the threaded rod 23 to prevent the threaded rod 23 from rotating. When the threaded rod 23 rises, the base plate 21 also rises.

[0026] In use, the tea leaves to be pressed are first placed inside the collection box 22. Then, the air hammer is driven by stepping on the foot pedal 8. The air hammer moves back and forth, causing the connecting rod 6 and the pressure plate to move continuously toward the inside of the collection box 22, pressing the tea leaves into bricks. This working principle is existing technology. When stepping on the foot pedal 8, the limiting component 9 must first be removed. The limiting component 9 protects the foot pedal 8 from impacts by falling objects, reducing safety hazards. First, the follower rod 20 is moved by pushing the grid plate 14. The follower rod 20 drives the moving block 12 located inside the moving groove 17 to slide through the transmission rod 15. The moving block 12 moves... During the process, the outer rod 19 moves towards the inner rod 18, causing the spring 16 to contract. As the follower rod 20 moves, the limiting rod 13 on the upper surface is misaligned with the bottom surface of the foot pedal 8, thus losing its limiting position. The foot pedal 8 can then be pressed down to work. At this time, the grid plate 14 is released, and the follower rod 20 moves towards the foot pedal 8 again through the restoring force of the spring 16. However, since the foot pedal 8 is being pressed down, the follower rod 20 can only contact the foot pedal 8. When the foot pedal 8 is released, it returns to a horizontal state, and the follower rod 20 slides directly into its bottom for limiting. The working principle is simple and convenient, and there is no need for manual adjustment of the limiting component 9 to reset, thus effectively increasing safety and automation.

[0027] After the tea bricks are pressed, the air hammer drives the connecting rod 6 and the pressure plate to move away from the inside of the collection box 22. At this time, the tea bricks inside the collection box 22 can be taken out. The movable base plate 21 effectively increases the convenience of collecting the tea bricks. The drive motor 26 drives the gear plate 27 to rotate. The gear plate 27 meshes with the driven gear 24 to drive it to rotate. After receiving the rotational power from the external driven gear 24, the threaded rod 23 inside the driven gear 24 also meshes with the threaded rod 23, so the threaded rod 23 rises vertically. The bottom of the threaded rod 23 is provided with a limit post 25, which prevents the threaded rod 23 from rotating on its own. When the threaded rod 23 rises, the base plate 21 also rises, making the tea bricks closer to the opening of the collection box 22, making them easier to take out.

[0028] With the shielding component 1 in place, the air hammer is in a closed state during operation, improving safety. When maintenance is required, two telescopic cylinders 35 extend in different directions, causing the first swing plate 32 to flip and unfold. Then, the second swing plate 33 flips towards the first swing plate 32, and the locking block 34 extends into the fitting groove 31 to lock and store the first swing plate 32 and the second swing plate 33. The air hammer is then exposed for maintenance. This tea pressing device increases the efficiency of tea pressing and improves ease of use, and can be widely promoted.
