[0029] Please see Figure 1-8 A vacuum sealing and shaping device for tea packaging includes a vacuum box 1, a door 2 installed on the front side of the vacuum box 1, a placement plate 5 fixedly connected to the bottom of the inner wall of the vacuum box 1, a placement groove 6 opened on the top of the placement plate 5, and two detachable sealing heat clamps 9 provided on the left side of the placement plate 5, with the right side of the sealing heat clamps 9 in contact with the left side of the placement plate 5.
[0030] Specifically, an electric push rod 7 is fixedly installed on the top of the inner wall of the vacuum chamber 1, corresponding to the position of the placement groove 6. The telescopic end of the electric push rod 7 is fixedly connected to a shaping pressure plate 8. A rubber buffer pad 28 is fixedly installed at the bottom of the shaping pressure plate 8. During the shaping process, it can effectively protect the tea packaging bag and avoid damage to the packaging bag due to excessive pressure, thus ensuring the integrity and aesthetics of the tea packaging bag. The size of the shaping pressure plate 8 is adapted to the placement groove 6. The tea packaging bag is squeezed and shaped by the cooperation between the shaping pressure plate 8 and the placement groove 6.
[0031] Specifically, a vacuum pump 3 is fixedly installed on the left side of the vacuum chamber 1, and an air extraction pipe is fixedly installed on the right side of the vacuum pump 3. The air extraction pipe is connected to the vacuum chamber 1. A control panel 4 is installed on the front side of the chamber door 2.
[0032] Specifically, the sealing heat clamp 9 is movably connected to the front side of the mounting block 10, and the front side of the mounting block 10 has a limit opening 11.
[0033] In practice, the first limiting block 12 is connected to the inside of the limiting port 11. The rear side of the first limiting block 12 is fixedly connected to the front side of the sealing hot clamp 9. Limiting grooves 13 are opened on the side of the two first limiting blocks 12 that are far apart from each other. Movable openings 14 are opened on the side of the two mounting blocks 10 that are far apart from each other.
[0034] Specifically, the movable port 14 and the limiting port 11 are interconnected, and the two mounting blocks 10 are fixedly connected to the opposite sides of each other by a fixing bracket 15.
[0035] In specific implementation, two movable rods 16 are provided on the side of the fixed frame 15 away from the mounting block 10. The end of the movable rod 16 near the mounting block 10 passes through the fixed frame 15 and extends to the inside of the fixed frame 15. The movable rod 16 is movably connected to the fixed frame 15. The ends of the two movable rods 16 away from the mounting block 10 are fixedly connected to the same handle 17. The ends of the two movable rods 16 away from the handle 17 are fixedly connected to the same movable plate 18. The movable plate 18 is in movable contact with the mounting block 10. The side of the movable plate 18 near the mounting block 10 is fixedly connected to a second limiting block 19. The side of the second limiting block 19 away from the movable plate 18 passes through the movable opening 14 and the limiting groove 13 in sequence and extends into the inside of the limiting groove 13. The second limiting block 19 is movably engaged with the limiting groove 13.
[0036] Specifically, the second limiting block 19 is movably connected to the movable port 14, a spring 20 is sleeved on the surface of the movable rod 16 and inside the fixed frame 15, and a servo motor 21 is fixedly connected to the left side of the front of the placement plate 5.
[0037] In practical implementation, the output end of the servo motor 21 is fixedly connected to the first screw 22, and the top of the first screw 22 is fixedly connected to the second screw 23. The threads of the first screw 22 and the second screw 23 are opposite in direction. The top of the second screw 23 is fixedly connected to the stop block 24. The surfaces of the first screw 22 and the second screw 23 are both threadedly connected to threaded plates 25. The left side of the threaded plates 25 is fixedly connected to the right side of the mounting block 10. In use, the servo motor 21 can drive the first screw 22 and the second screw 23 to rotate in opposite directions. Under the action of the threads, the two threaded plates 25 move away from each other or move closer to each other, thereby realizing that the two sealing heat clamps 9 move closer to each other or away from each other. The front side of the placement plate 5 is also fixedly connected to the support plate 26. The top of the support plate 26 is fixedly connected to the vertical rod 27. The threaded plates 25 are slidably sleeved on the vertical rod 27. The vertical rod 27 can guide the threaded plates 25 and prevent the threaded plates 25 from rotating with the screws.
[0038] In practical application: During use, place the tea bag in the placement slot 6, ensuring the bag opening is between the two sealing heat clamps 9. Then close the door 2, start the vacuum pump 3 to extract air from the vacuum chamber 1. Once the vacuum level reaches the set value, the vacuum pump 3 stops. Then, the electric push rod 7 drives the shaping plate 8 downwards, which squeezes and shapes the tea bag. Finally, start the sealing heat clamps 9 and the servo motor 21, which drives the first... The screws 22 and 23 rotate in the forward direction, causing the two threaded plates 25 to move closer to each other under the action of the threads. This, in turn, causes the two sealing heat clamps 9 to move closer to each other, thereby heat-sealing the opening of the packaging bag through the two sealing heat clamps 9. After sealing, the servo motor 21 drives the first screw 22 and the second screw 23 to rotate in the opposite direction, thereby resetting the two sealing heat clamps 9. Then, the electric push rod 7 drives the shaping pressure plate 8 to reset upward. Finally, the box door 2 is opened, and the packaging bag can be taken out. When the sealing heat clamp 9 needs to be disassembled and repaired, simply pull the handle 17 away from the limiting groove 13. This will cause the movable rod 16, movable plate 18, and second limiting block 19 to move away from the limiting groove 13, simultaneously compressing the spring 20. This will cause the second limiting block 19 to disengage from the limiting groove 13. Then, pull the sealing heat clamp 9 backward, causing the first limiting block 12 to move backward and disengage from the limiting opening 11. The sealing heat clamp 9 can then be removed for subsequent repairs. By following these steps, the sealing heat clamp 9 can be easily disassembled for repair without the need for other tools. This design greatly improves the convenience of repairing the sealing heat clamp 9, reduces downtime caused by malfunctions, and thus improves work efficiency.
