The second top rope fixture 446 pulls up the first rope buckle 64, so that the knot of the rope fork 441 is separated from the rope fork 441, and the rope hook 432 rotates to separate from the second packaging rope 63, and then the sixth clamp 445 continues to pull the first packaging rope 62 upward, so that the first packaging rope 62 and the second packaging rope 63 can bundle the tobacco 66. This work efficiency is very high. In this example, two packaging bags 67 (ie, the first packaging bag 60 and the second packaging bag 61) are used for packaging, which saves complicated bag making process and improves the packaging efficiency.

[0038] Preferably, the shaping mechanism 50 includes a second workbench 51, a positioning device 510 arranged on both sides of the second workbench 51, a rotating device 520 arranged on the upper side of the second workbench 51, a shaping device 530 arranged on the rotating device 520, and the clamping device 540; the shaping device 530 includes a shaping frame 531, and a leveling rod 532 arranged on the side of the shaping frame 531, the shaping frame 531 can be flipped and arranged on the rotating device 520, and the leveling rod 532 can swing toward the inner side of the shaping frame 531; the clamping device 540 includes a transfer frame 541 and a bracket 542 which can be raised and lowered and arranged on the transfer frame 541.

[0039] The tobacco that has completed the first bundling action on the first workbench 311 will be transported to the second workbench 51 by the second conveyor frame driven by the chain. In this embodiment, two bundlings are performed, namely longitudinal and transverse bundling. After completing the two bundlings, the shaping device 530 will shape the tobacco. The rotating device 520 can be used to turn the direction of the tobacco 66 so that the tobacco 66 completes the transverse and longitudinal bundling. The shaping device 530 further shapes the tobacco 66 that has completed packaging so that the packaging bag 67 and the tobacco 66 fit tightly. The positioning device 510 can be used to correct the position of the tobacco on the second workbench 51 so that the tobacco that has completed the guarantee is centered on the second workbench 51. During operation, the positioning device 510 first adjusts the position of the tobacco 66, the shaping device 530 shapes the tobacco 66, and then the rotating device 520 rotates the tobacco 66 in the horizontal direction, and then the packaging mechanism 40 bundles the tobacco 66 longitudinally (the first time is transverse bundling), and after bundling is completed, the second conveyor frame transports the tobacco 66 to the unloading mechanism 70. The unloading mechanism 70 may be a conveyor belt or a roller conveyor line, which can directly convey the tobacco 66 to a preset position.

[0040] Specifically, the rotating device 520 includes a second mounting frame 521 and a rotating frame 522, and the rotating frame 522 can be rotatably set on the second mounting frame 521; the shaping device 530 includes a shaping frame 531, and a flattening rod 532 set on the side of the shaping frame 531, the shaping frame 531 can be flipped and set on the rotating frame 522, and the flattening rod 532 can swing toward the inside of the shaping frame 531; the clamping device 540 includes a transfer frame 541 and a bracket 542 that can be raised and lowered on the transfer frame 541, and the transfer frame 541 is slidably set on the rotating frame 522 to place the bundled and packaged tobacco on the second workbench 51.

[0041] The rotating device 520 drives the shaping device 530 and the clamping device 540 to move toward the tobacco on the second workbench 51, and the second mounting frame 521 presses the top surface of the tobacco, and the second packaging bag fits the top of the tobacco. The shaping frame 531 opens, the transfer frame 541 slides outward, and then the transfer frame 541 slides inward, so that the bracket 542 holds up the tobacco, and the shaping frame 531 clamps and presses the packaging bag, so that the left and right sides of the tobacco and the packaging bag can be fully fitted. The rotating lifting device moves to adjust the direction of the tobacco. At this time, the shaping frame 531 shapes the front and back of the tobacco, so that the front and back of the tobacco and the packaging bag are fully fitted together. That is, the shaping device 530, the rotating lifting device, and the clamping device 540 cooperate to clamp and shape the tobacco and the packaging bag twice, so that the left and right sides, front and back sides, top surface, and bottom surface of the tobacco and the packaging bag are fully fitted together, and the leveling rod 532 can wipe the packaging bag again after each shaping, so that the appearance of the tobacco packaging can be guaranteed to be neat, which helps to reduce the loading space of the tobacco. The rotary lifting device is preferably a module driven by a cylinder or a screw.

[0042] Preferably, a plurality of rows of spherical protrusions are arranged at intervals on the second workbench 51. The spherical protrusions can allow the bottom of the tobacco to be suspended for a certain distance, so that it is convenient for the support rod on the bracket 542 to support the tobacco.

[0043] Preferably, the positioning device 510 includes a first positioning plate 511, a second positioning plate 512, a second mounting bracket 514, and a driving arm 516; the driving arm 516 connects the first positioning plate 511 and the second mounting bracket 514, and the second positioning plate 512 is arranged on the second mounting bracket 514; the output end of the first cylinder is connected to the second mounting bracket 514; the output end of the second cylinder is connected to the driving arm 516. The first positioning plate 511 and the second positioning plate 512 are provided with shaping bosses on the inner side. The first cylinder can lift the second mounting bracket 514. When the second mounting bracket 514 rises, the first positioning plate 511 and the second positioning plate 512 can both rise to a certain height at the same time, so that the first positioning plate 511 and the second positioning plate 512 can adjust the position of the tobacco on the second workbench 51. Among them, the driving arm 516 is hinged to the first positioning plate 511 and the second mounting bracket 514, so when the second cylinder is in motion, the shaping bosses on the two first positioning plates 511 can be swung from bottom to top to further smooth the surface of the packaging bag. It can be seen that under the joint action of the shaping frame 531, the leveling rod 532, the first positioning plate 511, and the second positioning plate 512, the packaging bag on the tobacco can be shaped multiple times, so that the upper and lower surfaces, left and right sides, and front and back sides of the tobacco can fully fit with the packaging bag, ensuring the neatness of the appearance, helping to reduce the loading space, and making it more convenient to load.

[0044] In summary, the design focus of the present invention is that a bagging mechanism 30, a packaging mechanism 40, and a shaping mechanism 50 are arranged between the upper tobacco mechanism 10 and the upper packaging bag mechanism 20. Among them, the upper tobacco mechanism 10 is used to load tobacco 66; the upper packaging bag mechanism 20 is used to provide packaging bags 67; the bagging mechanism 30 is used to wrap the upper and lower packaging bags 67 on the tobacco; the packaging mechanism 40 ties the packaging rope to the packaging bag so that the packaging bag can firmly wrap the tobacco and will not loosen; the shaping mechanism 50 is used to shape the packaged tobacco 66 so that the packaging bag 67 can be close to the tobacco 66; the unloading mechanism 70 is used to transport the packaged tobacco to a preset place. Therefore, the process of this type of tobacco conveyor is simpler, which is conducive to improving the efficiency of transportation and packaging.
