[0031] The present application provides a tobacco packaging and shaping mechanism, comprising a carrying platform 10; a positioning device 20 disposed on both sides of the carrying platform 10; a shaping device 30, a rotating lifting device 40, and a clamping device 50 disposed on the upper side of the carrying platform 10; the rotating lifting device 40 comprises a first mounting frame 41 and a rotating frame 42, wherein the rotating frame 42 is rotatably mounted on the first mounting frame 41; the shaping device 30 comprises a shaping frame 32 and a leveling rod 34 disposed on the side of the shaping frame 32, wherein the shaping frame 32 is reversibly mounted on the rotating frame 42, and the leveling rod 34 is swung toward the inside of the shaping frame 32; the clamping device 50 comprises a transfer frame 53 and a bracket 54 that is liftably mounted on the transfer frame 53, wherein the transfer frame 53 is slidably mounted on the rotating frame 42. Tobacco 16 covered with a packaging bag 15 is placed on the carrying platform 10. The rotary lifting device 40 drives the shaping device 30 and the clamping device 50 to move toward the tobacco 16 on the supporting platform 10. The first mounting frame 41 presses the top surface of the tobacco 16, so that the top of the packaging bag 15 and the tobacco 16 fit together, and the tobacco 16 fits together with the bottom of the packaging bag 15. The shaping frame 32 opens, and the transfer frame 53 slides outward. Then, the transfer frame 53 slides inward, so that the bracket 54 lifts the tobacco 16, and the shaping frame 32 clamps and presses the packaging bag 15, so that the tobacco 16 and the left and right sides of the packaging bag 15 fit together. The rotary lifting device 40 is activated to adjust the direction of the tobacco 16. At this time, the shaping frame 32 shapes the front and back of the tobacco 16, so that the tobacco 16 and the front and back of the packaging bag 15 fit together. That is, the shaping device 30, the rotating lifting device 40, and the clamping device 50 cooperate to clamp and shape the tobacco 16 and the packaging bag 15 twice, so that the left and right sides, front and back sides, top surface, and bottom surface of the tobacco 16 and the packaging bag 15 are fully fitted together, and the flattening rod 34 can wipe the packaging bag 15 again after each shaping, so that the appearance of the tobacco 16 packaging can be ensured to be neat, which helps to reduce the loading space of the tobacco 16.

[0032] Preferably, the support platform 10 is provided with a plurality of rows of spherical protrusions 13 at intervals. The spherical protrusions 13 can allow the bottom of the tobacco 16 to be suspended a certain distance, so that the support rod 55 on the bracket 54 can extend to the bottom of the tobacco 16 to support the tobacco 16.

[0033] Preferably, the support platform 10 includes a first support platform 11 and second support platforms 12 disposed on either side of the first support platform 11. The first support platform 11 is mounted on a lifting module 14. The lifting module 14 is powered by a pneumatic or hydraulic cylinder. The lifting module 14 can lift the first support platform 11, thereby lifting the tobacco 16.

The smoothing rod 34 is connected to the output end of the gear box 39. The drive rod 38 connected to the output end of the fifth cylinder 37 is connected to the input end of the gear box 39. The power of the fourth cylinder is transmitted to the first rotating shaft 31 via the first drive rod 36. When the first rotating shaft 31 rotates, the shaping frame 32 can swing up and down, thereby shaping the outer surface of the tobacco 16.

[0039] Preferably, the shaping frame 32 has a curved portion 33 near the first rotating shaft 31, and the curved portion 33 can be pressed against the edge of the top of the tobacco 16. The curved portion 33 can fully fit the top edge of the tobacco 16, so that the top edge of the tobacco 16 has a certain curvature without causing the edge of the tobacco 16 to collapse.

[0040] In summary, the key design feature of the present invention lies in its positioning device 20, which centers the packaged tobacco 16 on the support platform 10, facilitating subsequent shaping and clamping. The support platform 10, shaping device 30, rotary lifting device 40, and clamping device 50 work together to ensure that the packaging bag 15 is fully aligned with all exterior walls of the tobacco 16, resulting in a neat appearance, reduced loading space, and convenient loading.
