[0051] In this embodiment, Figure 3-Figure 7 As shown, the bag hanging device 200 is used to hang packaging bags, wherein the bag hanging device 200 includes a rotating mechanism 210 and several bag hanging mechanisms 220. The rotating mechanism 210 rotates the bag hanging mechanism 220 with several packaging bags to the bag taking station, and the bag hanging mechanism 220 is used to hang packaging bags and push the packaging bags forward.

[0052] In this embodiment, Figures 8-14As shown, the bag expanding device 300 is arranged beside the bag hanging device 200, and the bag expanding device 300 is used to remove the packaging bag on the bag hanging station and transfer it to the bag expanding station for expanding. The bag expanding device 300 includes a bag suction mechanism 310 for adsorbing the packaging bag on the bag hanging station, a first bag clamping mechanism 320 for clamping the packaging bag on the bag hanging station, a flipping mechanism 330 for flipping the clamped packaging bag to realize flipping the packaging bag from a vertical state to a horizontal state, and a rotating bag supporting mechanism 360 for opening the packaging bag on the bag suction mechanism 310 to realize that the mouth of the packaging bag is supported into a flat and long mouth shape.

[0053] In this embodiment, Figure 15-16 As shown, the feeding device 400 is arranged beside the bag expanding device 300, and the feeding device 400 is used to fix the packaging bag and put the material into the packaging bag. The feeding device 400 includes a feeding hopper 410, a second bag-holding mechanism 420 and two second bag-clamping mechanisms 430. The second bag-holding mechanism 420 is arranged below the feeding hopper 410 and is used to hold open and fix the packaging bag. The two second bag-clamping mechanisms 430 are respectively arranged on both sides of the feeding hopper 410. The second bag-clamping mechanism 430 is used to clamp and fix the packaging bag below the feeding hopper 410.

[0054] In this embodiment, Figure 17-Figure 19 As shown, the bag feeding device 500 is arranged at the bottom of the feeding device 400, and the bag feeding device 500 is used to transport the loaded packaging bags to the sealing device 600. The bag feeding device 500 includes a conveyor belt 510, a trolley 520 and two closing mechanisms 530. The conveyor belt 510 is arranged below the feeding device 400, and the trolley 520 is arranged below the feeding device 400 and above the conveyor belt 510. The trolley 520 reciprocates to transfer the loaded packaging bags to the conveyor belt 510, and the closing mechanism 530 is used to close the opening of the loaded packaging bags.

[0055] In this embodiment, Figure 20-21 As shown, the sealing device 600 is arranged on the side of the feeding device 400 and above the bag feeding device 500. The sealing device 600 is used to seal the opening of the packaging bag. The sealing device 600 includes a sealing mounting seat 610 and an introduction mechanism 620 fixed on the sealing mounting seat 610, an introduction drive mechanism 630 and a sealing mechanism 640. The sealing mechanism 640 is used to seal the opening of the packaging bag.

[0056] The bag-hanging rotary automatic packaging machine provided by the present invention utilizes the coordination between the bag-hanging device 200, the bag-expanding device 300, the feeding device 400, the bag-feeding device 500, and the sealing device 600 to enable the bag-hanging device 200 to provide multi-station bag supply. This allows workers to simply attach multiple bags to the bag-hanging device 200 at once, allowing the machine to operate for a longer period of time. Compared to the prior art method of manually attaching bags to the feeding device 400 one by one, this significantly reduces worker workload and effectively improves production efficiency. The bag-expanding device 300 automates bag suction, clamping, flipping, and supporting, reducing labor intensity and improving production efficiency. The feeding device 400 loads material into the bags, and the bag-feeding device 500 transports the loaded bags to the sealing device 600, which sews the bag openings shut. This achieves automatic loading and sealing, eliminating the need for manual operation and saving production costs. The packaging machine realizes automatic production from bag loading, unloading, conveying and bag sewing. No manual assistance is required in the middle. The degree of automation is high and manpower is saved.

[0057] In another embodiment of the present invention, Figure 3 As shown in FIG7 , the bag hanging device 200 is used to hang packaging bags, wherein the bag hanging device 200 includes a rotating mechanism 210 and a plurality of bag hanging mechanisms 220. The rotating mechanism 210 rotates the bag hanging mechanism 220 with a plurality of packaging bags to the bag taking station. The bag hanging mechanism 220 is used to hang the packaging bags and push the packaging bags forward.

[0058] In this embodiment, Figure 4 As shown, the rotating mechanism 210 includes a support base 211 fixedly connected to the frame 100. A rotating drive motor 212 and a rotating frame 213 connected to the output shaft of the rotating drive motor 212 are fixedly mounted above the support base 211. In this embodiment, the rotating mechanism 210 controls the movement of the rotating frame 213 via the rotating drive motor 212. When the bag hanging rod 232 is loaded, the positions of several bag hanging mechanisms 220 can be interchanged, and the loaded packaging bags can be rotated to the bag removal station.

[0059] In this embodiment, Figure 5-Figure 6As shown, the bag hanging mechanism 220 includes a bag hanging assembly 230 for hanging packaging bags, a bag pushing assembly 240 for pushing the packaging bags forward, and a bag separating assembly 244 for separating the pushed forward packaging bags. The bag hanging assembly 230 includes a bag hanging plate 231 connected to the rotating mechanism 210 and a bag hanging rod 232 connected to the bag hanging plate 231. There are four bag hanging assemblies 230, each of which includes a bag hanging plate 231 and two bag hanging rods 232. The two bag hanging rods 232 are symmetrically arranged on the bag hanging plate 231, and multiple packaging bags are stacked and hung on the two bag hanging rods 232. When one bag hanging plate 231 rotates to the bag retrieval working position, the other bag hanging plate 231 is in the loading position. The four bag hanging plates 231 are driven by the rotating mechanism 210 to circulate between the four working stations, greatly improving the loading speed.

[0060] When the bag-dividing assembly 244 is preferably a bag-dividing brush, the bag-dividing brush includes a set of brush holders connected to the bag-hanging plate 231, and a brush is connected to the bottom surface of the brush holder, and the brush separates the adhered packaging bags. When the bag-dividing assembly 244 is also an iron sheet, the iron sheet is connected to the frame 100, and the iron sheet separates the adhered packaging bags. It should be noted that the bag-dividing assembly 244 can also be other bag-dividing components that can separate adhered packaging bags. This embodiment is not specifically limited, and the corresponding bag-dividing assembly 244 can be adapted according to actual use.

[0061] In this embodiment, Figure 7As shown, the bag pushing assembly 240 includes a bag pushing drive assembly 241 disposed within the rotating mechanism 210 and a bag pushing plate 242 driven by the bag pushing drive assembly 241. The bag pushing plate 242 is driven by the bag pushing drive assembly 241 to reciprocate and translate along the direction corresponding to the bag hanging rod 232 to push the packaged bags. The bag separating assembly 244 separates stuck packages. A package bag detection sensor 243 is embedded in the bag pushing plate 242 to detect the presence of packages. Four bag pushing assemblies 240 are provided, each comprising a bag pushing drive assembly 241 and a bag pushing plate 242. The bag pushing drive assembly 241 is disposed on the inner surface of the rotating frame 213. The bag pushing drive assembly 241 drives the bag pushing plate 242 to reciprocate and translate along the direction corresponding to the bag hanging rod 232 to push the packaged bags. The bag separating assembly 244 separates stuck packages. When the bag pushing assembly 240 in this embodiment is in motion, the bag pushing plate 242 is driven by the bag pushing driving assembly 241 to move back and forth along the extension direction of the corresponding bag hanging rod 232 to push the packaging bag. In the process of pushing the packaging bag, the bag separating assembly 244 separates the packaging bags that are stuck together, thereby facilitating the bag expanding device 300 to remove the packaging bag on the outer end side of the corresponding bag hanging rod 232.

[0062] The bag pushing drive assembly 241 in this embodiment includes a first connecting base 245 connected to the inner bottom surface of the rotating frame 213. A lifting cylinder 246 is mounted on the first connecting base 245. The output shaft of the lifting cylinder 246 is connected to a connecting plate 247. A bag pushing plate drive motor 248 is mounted on the bottom surface of the connecting plate 247. The output shaft of the bag pushing plate drive motor 248 passes through the connecting plate 247 and is connected to a driving bevel gear 249. The bag pushing drive assembly 241 also includes a screw assembly 250 disposed on the bag hanging plate 231 and connected to the driving bevel gear 249. The screw assembly 250 includes a screw 251 connected to the bag pushing plate 242, a screw nut 252 threadedly connected to the outer surface of the screw 251, and a driven bevel gear 253 meshing with the driving bevel gear 249. The driving bevel gear 249 and the driven bevel gear 253 rotate simultaneously due to the bag pushing plate drive motor 248. The driving bevel gear 249 is driven to rotate by the bag pushing plate driving motor 248. Since the driving bevel gear 249 is meshed and connected with the driven bevel gear 253, the driving bevel gear 249 drives the driven bevel gear 253 to rotate during the rotation process. The driven bevel gear 253 drives the screw rod 251 to reciprocate during the rotation process, thereby driving the bag pushing plate 242 to reciprocate, thereby realizing reciprocating translation pushing of the packaging bag.

[0063] The bag hanging device 200 includes the following steps when in operation:

[0064] Step S100: During use, a worker hangs packaging bags on the bag hanging rod 232, controls the rotation of the rotating frame 213 through the rotating drive motor 212, rotates the bag hanging rod 232 with several packaging bags to the bag taking station, and supplies the packaging bags to the bag expanding device 300, and then hangs packaging bags on the other bag hanging rods 232.

[0065] Step S110: After the rotary drive motor 212 rotates the bag hanging rod 232 with the packaging bag hung on it to the bag taking station, the bag pushing drive component 241 drives the bag pushing plate 242 to move back and forth along the extension direction of the bag hanging rod 232 to push the packaging bag. In the process of pushing the packaging bag, the bag separating component 244 separates the packaging bags that are stuck together, so that the bag expanding device 300 can take away the packaging bag corresponding to the outer end side of the hanging bag.

[0066] Step S120: When the packaging bag detection sensor 243 cannot detect the packaging bag, the rotary drive motor 212 controls the rotation of the rotating frame 213 to rotate the bag hanging rod 232 with several packaging bags hanging on it to the bag taking station, thereby realizing uninterrupted bag supply. At the same time, the bag pushing plate 242 of the bag pushing mechanism pushes the packaging bags on the bag hanging rod 232 outward in time to replenish the packaging bags, so as to facilitate the next bag taking by the bag expanding device 300.

[0067] In another embodiment of the present invention, Figure 8-Figure 9 As shown, the bag expanding device 300 is arranged beside the bag hanging device 200, and the bag expanding device 300 is used to remove the packaging bag on the bag hanging station and transfer it to the bag expanding station for expanding. The bag expanding device 300 includes a bag suction mechanism 310 for adsorbing the packaging bag on the bag hanging station, a first bag clamping mechanism 320 for clamping the packaging bag on the bag hanging station, a flipping mechanism 330 for flipping the clamped packaging bag to realize flipping the packaging bag from a vertical state to a horizontal state, and a rotating bag supporting mechanism 360 for opening the packaging bag on the bag suction mechanism 310 to realize that the mouth of the packaging bag is supported into a flat and long mouth shape.

[0068] In this embodiment, Figure 10As shown, the bag suction mechanism 310 includes a first bag suction mechanism 311 for sucking the packaging bags on the bag pushing station, the first bag suction mechanism 311 includes a second connecting seat 312 connected to the frame 100, and a group of vacuum suction cup cylinders 313 are provided on the second connecting seat 312, and the output shafts of the two vacuum suction cup cylinders 313 are connected to the first connecting rod 314, and the first connecting rod 314 is connected to the suction cup connecting plate 315 at one end away from the output shaft of the vacuum suction cup cylinder 313, and the left side of the suction cup connecting plate 315 is fixedly connected to the vacuum suction cup 316, and the vacuum suction cup cylinder 313 drives the vacuum suction cup 316 to reciprocate by driving the first connecting rod 314 to achieve suction of the packaging bag.

[0069] A first rotating shaft 317 is provided at the connection between the suction cup connecting plate 315 and the first connecting rod 314, enabling a rotational connection. A connecting ear (not labeled) is integrally formed on the inner sidewall of the suction cup connecting plate 315. A connecting post 318 is provided on the second connecting seat 312, connected to the connecting ear (not labeled). A second rotating shaft 319 is provided on the connecting ear (not labeled) and the connecting post 318, enabling a rotational connection. The first bag suction mechanism 311 described in this embodiment moves to the bag removal station to remove bags. The vacuum suction cup cylinder 313 of the first bag suction mechanism 311 drives the first connecting rod 314 to reciprocate. The other end of the first connecting rod 314 drives the suction cup connecting plate 315, which is connected to the first rotating shaft 317, to swing about the first rotating shaft 317, thereby driving the vacuum suction cup 316 to swing, thereby sucking and removing the packaging bag. In this implementation example, when the vacuum suction cup 316 rotates to one side of the packaging bag along with the suction cup connecting plate 315, the vacuum suction cup 316 is connected to the vacuum air source through the air source pipeline, and the vacuum air source draws air from the vacuum suction cup 316 to generate vacuum and absorb the packaging bag.

[0070] In this embodiment, Figure 11As shown, the first bag clamping mechanism 320 includes a supporting plate 321 connected to the frame 100. A guide plate 322 is connected to one side of the supporting plate 321. A support plate 323 is fixedly mounted on the bottom surface of the supporting plate 321. A group of first bag clamping cylinders 324 are symmetrically arranged on the bottom surface of the support plate 323. The output shaft of the first bag clamping cylinder 324 is connected to a second connecting rod 325. The second connecting rod 325 is connected to a clamping claw 326 at one end away from the output shaft of the first bag clamping cylinder 324. The first bag clamping cylinder 324 drives the second connecting rod 325 to relatively clamp or release the clamping claw 326. The second bag clamping mechanism 430 of this embodiment uses the first bag clamping cylinder 324 to drive the second connecting rod 325 to move. During the movement of the second connecting rod 325, the clamping claw 326 is rotated to control the closing of the clamping claw 326, thereby achieving the clamping and release of the packaging bag.

[0071] In this embodiment, Figure 12 As shown, the flip mechanism 330 includes a flip connecting plate 331 connected to the frame 100. A flip cylinder 332 is connected to the flip connecting plate 331. The output shaft of the flip cylinder 332 is connected to a third connecting rod 333. The end of the third connecting rod 333 away from the output shaft of the flip cylinder 332 is rotatably connected to a clamping clamp 334. The clamping clamp 334 clamps a rotating shaft 335 connected to the bottom surface of the supporting plate 321. The flip cylinder 332 drives the third connecting rod 333 to rotate the clamping clamp 334 and the rotating shaft 335 to flip the supporting plate 321. Rotating shaft connecting seats 336 connected to the frame 100 are symmetrically provided on both sides of the rotating shaft 335. The rotating shaft 335 is rotatably connected to the rotating shaft connecting seats 336. The flipping mechanism 330 flips the unopened packaging bag sucked by the first bag suction mechanism 311 onto the supporting plate 321. Specifically, the flipping cylinder 332 drives the third connecting rod 333 to move, and the other end of the third connecting rod 333 drives the clamping clamp 334 connected to it to rotate. The clamping clamp 334 thereby drives the rotating shaft 335 to rotate on the rotating shaft connecting seat 336, and further drives the supporting plate 321 to flip from a vertical state to a horizontal state, thereby flipping the packaging bag and conveying it to the corresponding bag-supporting station.

[0072] In this embodiment, Figure 13As shown, the bag suction mechanism 310 also includes a second bag suction mechanism 340 for adsorbing the upper and lower surfaces of the flipped packaging bag, wherein the second bag suction mechanism 340 includes an upper bag suction component 341 and a lower bag suction component 348, the upper bag suction component 341 is arranged above the lower bag suction component 348, the upper bag suction component 341 is used to adsorb the upper bag surface of the packaging bag, and the lower bag suction component 348 is used to adsorb the lower bag surface of the packaging bag, and the bag opening of the packaging bag is sucked open through the cooperation between the upper bag suction component 341 and the lower bag suction component 348.

[0073] The upper bag suction assembly 341 includes a connecting frame 342 connected to the frame 100. An upper vacuum cup cylinder 343 is connected to one side of the connecting frame 342. The output shaft of the upper vacuum cup cylinder 343 is connected to an upper cup mounting plate 344. A plurality of upper vacuum cups 345 are evenly spaced on the upper cup mounting plate 344. The upper vacuum cup cylinder 343 drives the upper cup mounting plate 344 to move so that the upper vacuum cups 345 can absorb the upper surface of the packaging bag. The upper vacuum cup cylinder 343 drives the upper cup mounting plate 344 to move downward, and the plurality of upper vacuum cups 345 on the upper cup mounting plate 344 absorb the upper surface of the packaging bag. After the plurality of upper vacuum cups 345 have absorbed the upper surface of the packaging bag, the upper vacuum cup cylinder 343 drives the upper cup mounting plate 344 to move upward, causing the upper surface of the packaging bag to be opened.

[0074] A set of guide rods 346 are symmetrically arranged on the upper suction cup mounting plate 344. Slide blocks 347 connected to the connecting frame 342 are slidably connected to the two guide rods 346. Driven by the upper vacuum cup cylinder 343, the guide rods 346 are synchronously driven to move back and forth horizontally on the slide blocks 347.

[0075] It should be noted that in this embodiment, four upper vacuum suction cups 345 are provided. The four upper vacuum suction cups 345 are distributed on the upper suction cup mounting plate 344 and are all connected to the vacuum air source through an air source pipeline. The vacuum air source draws air from the upper vacuum suction cups 345 to produce vacuum adsorption, thereby adsorbing the upper bag surface of the packaging bag. The installation position of the upper vacuum suction cups 345 can be adjusted to accommodate packaging bags of different sizes. The number and installation position of the upper vacuum suction cups 345 are not limited to this and can be changed accordingly as needed, as long as they can adsorb the packaging bag and cooperate with the lower bag suction assembly 348 to open the bag opening of the packaging bag.

[0076] The lower bag suction assembly 348 includes a set of connecting blocks 349 disposed on the bottom surface of the carrier plate 321. The end of the connecting block 349 away from the carrier plate 321 is connected to a lower suction cup mounting plate 350. Several lower vacuum cups 351 are evenly spaced on the lower suction cup mounting plate 350. These lower vacuum cups 351 apply suction to the lower surface of the packaging bag. When the packaging bag is flipped onto the carrier plate 321, the lower vacuum cups 351 apply suction to the lower surface of the packaging bag, allowing the rotating bag-opening mechanism 360 to quickly open the packaging bag.

[0077] It should be noted that in this embodiment, three lower vacuum suction cups 351 are provided. The three lower vacuum suction cups 351 are distributed on the lower suction cup mounting plate 350 and are all connected to the vacuum air source through an air source pipeline. The vacuum air source draws air from the lower vacuum suction cups 351 to produce vacuum adsorption, thereby adsorbing the lower bag surface of the packaging bag. The installation position of the lower vacuum suction cups 351 can be adjusted to accommodate packaging bags of different sizes. The number and installation position of the lower vacuum suction cups 351 are not limited to this and can be changed accordingly as needed, as long as they can adsorb the packaging bag and cooperate with the upper bag suction assembly 341 to open the bag opening of the packaging bag.

The output shaft of the drive motor 363 is connected to a rotating shaft 364, and the bag-opening assembly 365 is mounted on the rotating shaft 364. In this embodiment, the drive motor 363 of the rotating assembly 361 drives the rotating shaft 364 to rotate. During rotation, the rotating shaft 364 drives the bag-opening assembly 365 to rotate toward the bag opening. After the bag-opening assembly 365 completes its bag-opening operation, the rotating assembly 361 transfers the opened bag to the next workstation.

[0079] The bag-supporting assembly 365 includes a pair of bag-supporting connecting seats 366 mounted on the rotating shaft 364. A bag-supporting member 367 is rotatably connected to each of the two bag-supporting connecting seats 366. The inner sidewalls of each bag-supporting member 367 are each provided with a first connecting member 368. A bag-supporting cylinder 369 is connected to one of the first connecting members 368. The output shaft of the bag-supporting cylinder 369 is connected to a fourth connecting rod 370. The fourth connecting rod 370, at one end away from the output shaft of the bag-supporting cylinder 369, is connected to the other first connecting member 368. The bag-supporting member 367 includes a bag-supporting plate 371 connected to the bag-supporting connecting seats 366 and a bag-supporting piece 372 disposed below and in the middle of the bag-supporting plate 371.

The bag-stretching assembly 365 in this embodiment drives the fourth connecting rod 370 to move through the bag-stretching cylinder 369, and the other end of the fourth connecting rod 370 drives the bag-stretching member 367 connected to the first connecting member 368 to swing around the bag-stretching connecting seat 366, so that one bag-stretching member 367 approaches or moves away from the other bag-stretching member 367, thereby enabling the bag-stretching plate 371 and the bag-stretching piece 372 of the bag-stretching member 367 to stretch the packaging bag, so that the bag opening of the packaging bag is stretched into a flat and long mouth shape. When the bag-stretching assembly 365 completes the bag-stretching action on the packaging bag, the rotating assembly 361 transports the stretched packaging bag to the next workstation.

[0080] The bag expansion device 300 includes the following steps when in operation:

[0081] Step S200: When in use, the first bag suction mechanism 311 moves to the bag taking station to take the bag, and the vacuum suction cup cylinder 313 of the first bag suction mechanism 311 drives the first connecting rod 314 to reciprocate, and the other end of the first connecting rod 314 drives the suction cup connecting plate 315 connected to the first rotating shaft 317 to swing around the first rotating shaft 317, thereby driving the vacuum suction cup 316 to swing, thereby performing the bag adsorption and bag taking operation on the packaging bag.

[0082] Step S210: After the packaging bag is adsorbed, the first bag clamping cylinder 324 of the first bag clamping mechanism 320 drives the second connecting rod 325 to move.

[0084] Step S230: When the packaging bag is flipped onto the supporting plate 321, the lower vacuum suction cup 351 of the lower suction bag assembly 348 of the second suction bag mechanism 340 adsorbs the lower bag surface of the packaging bag, and the upper suction cup mounting plate 344 is driven downward by the upper vacuum suction cup cylinder 343 of the upper suction bag assembly 341, and the several upper vacuum suction cups 345 on the upper suction cup mounting plate 344 adsorb the upper bag surface of the packaging bag. After the several upper vacuum suction cups 345 adsorb the upper bag surface of the packaging bag, the upper vacuum suction cup cylinder 343 drives the upper suction cup mounting plate 344 to move upward, so as to suck open the bag mouth of the packaging bag.

[0085] Step S240: After the bag opening of the packaging bag is sucked open, the driving motor 363 of the rotating component 361 of the rotating bag-holding mechanism 360 drives the rotating shaft 364 to rotate, and the rotating shaft 364 drives the bag-holding component 365 to rotate toward the bag direction of the packaging bag during the rotation process, and the bag-holding cylinder 369 of the bag-holding component 365 drives the fourth connecting rod 370 to move, and the other end of the fourth connecting rod 370 drives the bag-holding component 367 connected to the first connecting member 368 to swing around the bag-holding connecting seat 366, so that one bag-holding component 367 approaches or moves away from the other bag-holding component 367, thereby realizing that the bag-holding plate 371 and the bag-holding piece 372 of the bag-holding component 367 hold the packaging bag open, so that the bag opening of the packaging bag is held into a flat and long mouth shape.

[0086] Step S250 : After the bag-opening assembly 365 completes the bag-opening action on the packaging bag, the rotating assembly 361 transfers the expanded packaging bag to the unloading station.
