Description

Technical Field

[0001] The present invention relates to the technical field of conveyors, and in particular to a tobacco conveyor. Background Art

[0002] In the tobacco industry, tobacco bags are mostly used to load and unload tobacco during the processes of tobacco packaging, transportation, and storage. During production, tobacco is first compressed into blocks in a compressor, and then the tobacco is packed into a bag. After packing, it is transported to the next production workshop. Tobacco is an important part of the national economy, and the consumption of tobacco is very large. However, the packing process of some tobacco packing and conveying equipment is designed to be relatively complex, resulting in low packing and conveying efficiency.

[0003] For example, a tobacco loading device disclosed in Chinese Patent Application No.: CN201721105275. The tobacco loading device includes a bag-making device, a loading device, and a bag-sealing device, and the bag-making device, the loading device, and the bag-sealing device are connected in sequence. When this tobacco loading device works, it is necessary to first compress the tobacco separately, make the packaging bag separately, then load it into the packaging bag, and finally seal it. It can be seen that the packing process of this kind of tobacco is designed to be very complex, resulting in low packing and conveying efficiency. Summary of the Invention

[0004] In view of this, in view of the deficiencies of the existing technology, the main purpose of the present invention is to provide a tobacco conveyor with a simpler process and higher packing and conveying efficiency, thereby overcoming the deficiencies of the existing technology.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] The present application provides a tobacco conveyor, including an upper tobacco mechanism and an upper packaging bag mechanism; a bagging mechanism, a packing mechanism, and a shaping mechanism are arranged between the upper tobacco mechanism and the upper packaging bag mechanism;

[0007] Among them, the upper packaging bag mechanism can convey the packaging bag to the bagging mechanism; the upper tobacco mechanism can convey the tobacco to the bagging mechanism, and the bagging mechanism wraps the packaging bag around the tobacco; the packing mechanism binds the packing rope to the packaging bag; a blanking mechanism is arranged beside the shaping mechanism and can send out the packaged tobacco.

[0008] The present invention has obvious advantages and beneficial effects compared with the prior art. Specifically, as can be seen from the above technical solutions, a bagging mechanism, a packing mechanism, and a shaping mechanism are provided between the upper tobacco mechanism and the upper packaging bag mechanism. Among them, the upper tobacco mechanism is used to load tobacco; the upper packaging bag mechanism is used to provide packaging bags; the bagging mechanism is used to wrap the upper and lower packaging bags around the tobacco; the packing mechanism binds the packing rope to the packaging bag so that the packaging bag can firmly wrap the tobacco and will not loosen; the shaping mechanism is used to shape the tobacco after packing so that the packaging bag can closely adhere to the tobacco; the blanking mechanism is used to convey the packed tobacco to a preset place. Therefore, the packaging, conveying and other processes of such a tobacco conveyor are simpler, which is conducive to improving the conveying and packing efficiency.

The first rope jacking jig 443 jacks up the first packaging rope 62 upwards to the sixth clamp 445, and the sixth clamp 445 clamps the position near the end of the first packaging rope 62. 7. The second rope jacking jig 446 smooths up the first rope buckle 64, so that the rope knot of the rope winding fork 441 disengages from the rope winding fork 441, and the rope hook 432 rotates and disengages from the second packaging rope 63. Then, the sixth clamp 445 continues to pull the first packaging rope 62 upwards, so that the first packaging rope 62 and the second packaging rope 63 can tie up the tobacco 66 well. This working efficiency is very high. In this example, two packaging bags 67 (i.e., the first packaging bag 60 and the second packaging bag 61) are used for packaging, eliminating the complicated bag-making process and having a higher packaging and packing efficiency.

[0045] Preferably, the shaping mechanism 50 includes a second workbench 51, positioning devices 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 flattening rod 532 arranged beside the shaping frame 531. The shaping frame 531 is rotatably arranged on the rotating device 520, and the flattening rod 532 can swing towards the inner side of the shaping frame 531; the clamping device 540 includes a transfer frame 541 and a bracket 542 that can be lifted and lowered on the transfer frame 541.

[0046] The tobacco that has completed the first bundling action on the first workbench 311 will be conveyed by the chain-driven second conveyor to the second workbench 51. In this embodiment, two bundling operations are performed, namely longitudinal and transverse bundling. After the two bundling operations are completed, 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 can complete the transverse and longitudinal bundling. The shaping device 530 further shapes the packaged tobacco 66 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 guaranteed tobacco 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, then the rotating device 520 rotates the tobacco 66 in the horizontal direction, and then the packing mechanism 40 performs longitudinal bundling on the tobacco 66 (the first time is transverse bundling). After the bundling is completed, the second conveyor conveys the tobacco 66 to the blanking mechanism 70. Among them, the blanking mechanism 70 can be a conveyor belt or a roller conveyor line, which can directly convey the tobacco 66 to a preset position.

[0047] Specifically: The rotating device 520 includes a second mounting frame 521 and a rotating frame 522, and the rotating frame 522 is rotatably arranged on the second mounting frame 521; the shaping device 530 includes a shaping frame 531 and a flattening rod 532 arranged beside the shaping frame 531. The shaping frame 531 is flipably arranged on the rotating frame 522, and the flattening rod 532 can swing towards the inner side of the shaping frame 531; the clamping device 540 includes a transfer frame 541 and a bracket 542 that can be lifted and lowered on the transfer frame 541. The transfer frame 541 is slidably arranged on the rotating frame 522. The tobacco that has completed the bundling and packaging is placed on the second workbench 51.

[0048] The rotating device 520 drives the shaping device 530 and the clamping device 540 to move towards the tobacco on the second workbench 51. The second mounting frame 521 presses the top surface of the tobacco, and the second packaging bag fits with the top of the tobacco. The shaping frame 531 opens, the transfer frame 541 slides outwards, and then the transfer frame 541 slides inwards so that the bracket 542 lifts the tobacco, and the shaping frame 531 clamps the packaging bag, so that the left and right sides of the tobacco and the packaging bag can fit fully. The rotating and lifting device operates to adjust the direction of the tobacco. At this time, the shaping frame 531 shapes the front and rear surfaces of the tobacco so that the front and rear surfaces of the tobacco and the packaging bag fit fully together. That is, the shaping device 530, the rotating and 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, the front and rear sides, the top surface, and the bottom surface of the tobacco and the packaging bag fit fully together. The flattening rod 532 can also wipe the packaging bag again after each shaping, so that the appearance neatness of the tobacco packaging can be guaranteed, which helps to reduce the loading space of the tobacco. The rotating and lifting device is preferably a cylinder or a module driven by a screw rod.

[0049] Preferably, a plurality of rows of spherical protrusions are arranged at intervals on the second workbench 51. The spherical protrusions can keep the bottom of the tobacco suspended at a certain distance, which facilitates the tobacco to be lifted by the support rods on the support 542.

[0050] 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 inner sides of the first positioning plate 511 and the second positioning plate 512 are provided with shaping bosses. 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 by 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. Therefore, when the second cylinder acts, the shaping bosses on the two first positioning plates 511 can swing from bottom to top to further smooth the surface of the packaging bag. Thus, under the combined action of the shaping frame 531, the smoothing 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 be fully attached to the packaging bag, ensuring the neatness of the appearance, helping to reduce the loading space, and making it more convenient during loading.

[0051] In summary, the design focus of the present invention is that a bagging mechanism 30, a packing mechanism 40, and a shaping mechanism 50 are arranged between the tobacco mechanism 10 and the upper packaging bag mechanism 20. Among them, the upper tobacco mechanism 10 is used to load the tobacco 66; the upper packaging bag mechanism 20 is used to provide the packaging bag 67; the bagging mechanism 30 is used to wrap the upper and lower two packaging bags 67 around the tobacco; the packing mechanism 40 binds the packing rope to the packaging bag so that the packaging bag can firmly wrap the tobacco and will not come loose; the shaping mechanism 50 is used to shape the tobacco 66 after packing so that the packaging bag 67 can closely adhere to the tobacco 66; the blanking mechanism 70 is used to convey the packed tobacco to a preset place. Therefore, the process of this tobacco conveyor is simpler, which is beneficial to improving the conveying and packing efficiency.
