Among them, the rotating bag supporting mechanism 600 includes a rotating component 610 and a bag supporting component 620 for expanding the packaging bag on the second sucking bag mechanism 500.

[0045] In another embodiment of the present invention, as Figure 3As shown in the figure, the first bag suction mechanism 200 includes a first connecting seat 201 connected to the frame 100. A set of vacuum suction cup cylinders 202 are arranged on the first connecting seat 201. Output shafts of the two vacuum suction cup cylinders 202 are both connected with a first connecting rod 203. One end of the first connecting rod 203 away from the output shaft of the vacuum suction cup cylinder 202 is connected with a suction cup connecting plate 204. A vacuum suction cup 205 is fixedly connected to the left side of the suction cup connecting plate 204. A first rotating shaft 206 for realizing rotational connection is arranged at the connection position between the suction cup connecting plate 204 and the first connecting rod 203. A connecting ear 207 is integrally formed on the inner side wall of the suction cup connecting plate 204. A connecting column 208 connected with the connecting ear 207 is arranged on the first connecting seat 201. A second rotating shaft 209 for realizing rotational connection is arranged on the connecting ear 207 and the connecting column 208. In this embodiment, the first bag suction mechanism 200 moves to the bag taking station to take a bag. The vacuum suction cup cylinder 202 of the first bag suction mechanism 200 drives the first connecting rod 203 to reciprocate. The other end of the first connecting rod 203 drives the suction cup connecting plate 204 connected with the first rotating shaft 206 to swing around the first rotating shaft 206, thereby driving the vacuum suction cup 205 to swing, so as to perform an adsorption bag taking operation on the packaging bag. In this implementation example, when the vacuum suction cup 205 rotates to one side of the packaging bag along with the suction cup connecting plate 204, the vacuum suction cup 205 is communicated with a vacuum pumping air source through an air source pipeline, and the vacuum pumping air source pumps air to the vacuum suction cup 205 to generate vacuum to adsorb the packaging bag.

[0046] In another embodiment of the present invention, as Figure 4 shown in the figure, the bag clamping mechanism 300 includes a bearing plate 301. A guide plate 302 is connected to one side of the bearing plate 301. A support plate 303 is fixedly installed on the bottom surface of the bearing plate 301. A set of bag clamping cylinders 304 are symmetrically arranged on the bottom surface of the support plate 303. Output shafts of the bag clamping cylinders 304 are connected with a second connecting rod 305. One end of the second connecting rod 305 away from the output shaft of the bag clamping cylinder 304 is connected with a clamping jaw 306. The bag clamping cylinder 304 drives the second connecting rod 305 to drive the clamping jaw 306 to clamp or loosen relatively; A first connecting member 307 connected with the clamping jaw 306 is further arranged on the bottom surface of the support plate 303. A third rotating shaft 308 for realizing rotation of the first connecting member 307 and the clamping jaw 306 is penetrated and connected on the first connecting member 307. In the bag clamping mechanism 300 of this embodiment, the bag clamping cylinder 304 drives the second connecting rod 305 to move. During the movement of the second connecting rod 305, the clamping jaw 306 is driven to rotate, thereby controlling the closing of the clamping jaw 306, so as to realize clamping and loosening of the packaging bag.

[0047] In another embodiment of the present invention, asFigure 5 As shown, the flipping mechanism 400 includes a flipping connecting plate 401 connected to the frame 100. A flipping cylinder 402 is connected to the flipping connecting plate 401. The output shaft of the flipping cylinder 402 is connected to a third connecting rod 403. One end of the third connecting rod 403 away from the output shaft of the flipping cylinder 402 is rotatably connected to a clamping clip 404. A rotating shaft 405 connected to the bottom surface of the bearing plate 301 is clamped by the clamping clip 404. The flipping cylinder 402 drives the third connecting rod 403 to drive the clamping clip 404 and the rotating shaft 405 to rotate to achieve the flipping of the bearing plate 301. Symmetrically arranged on both sides of the rotating shaft 405 are rotating shaft connection seats 406 connected to the frame 100. The rotating shaft 405 is rotatably connected to the rotating shaft connection seats 406. The flipping mechanism 400 flips the unopened packaging bag sucked by the first bag sucking mechanism 200 onto the bearing plate 301. Specifically, the flipping cylinder 402 drives the third connecting rod 403 to move. The other end of the third connecting rod 403 drives the clamping clip 404 rotatably connected thereto to rotate. The clamping clip 404 thus drives the rotating shaft 405 to rotate on the rotating shaft connection seats 406, and further drives the bearing plate 301 to flip from the vertical state to the horizontal state, thereby flipping and conveying the packaging bag to the corresponding bag supporting station.

[0048] In another embodiment of the present invention, as Figure 6 shown, the upper bag sucking assembly 510 includes a connecting frame 511 connected to the frame 100. An upper vacuum suction cup cylinder 512 is connected to one side of the connecting frame 511. The output shaft of the upper vacuum suction cup cylinder 512 is connected to an upper suction cup mounting plate 513. A plurality of upper vacuum suction cups 205 are equidistantly arranged on the upper suction cup mounting plate 513. The upper vacuum suction cup cylinder 512 drives the upper suction cup mounting plate 513 to move to achieve the adsorption of the upper bag surface of the packaging bag by the upper vacuum suction cups 205. By driving the upper suction cup mounting plate 513 to move downward by the upper vacuum suction cup cylinder 512, a plurality of the upper vacuum suction cups 205 on the upper suction cup mounting plate 513 adsorb the upper bag surface of the packaging bag. When a plurality of the upper vacuum suction cups 205 adsorb the upper bag surface of the packaging bag, the upper vacuum suction cup cylinder 512 drives the upper suction cup mounting plate 513 to move upward, so that the upper bag surface of the packaging bag is in an open state.

[0049] Specifically, a set of guide rods 515 are symmetrically arranged on the upper suction cup mounting plate 513. Sliders 516 connected to the connecting frame 511 are slidably connected to both of the two guide rods 515. Under the driving action of the upper vacuum suction cup cylinder 512, the guide rods 515 are synchronously moved to drive the guide rods 515 to reciprocate horizontally back and forth on the sliders 516. ​

[0050] It should be noted that four upper vacuum suckers 205 are provided in this embodiment. The four upper vacuum suckers 205 are distributed on the upper sucker mounting plate 513 and are all connected to a vacuum pumping air source through an air source pipeline. The vacuum pumping air source pumps air to the upper vacuum suckers 205 to generate vacuum adsorption, and then adsorbs the upper side surface of the packaging bag. The installation position of the upper vacuum suckers 205 is adjustable to suit packaging bags of different sizes. The number and installation position of the upper vacuum suckers 205 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 sucking assembly 520 to open the bag mouth of the packaging bag.

[0051] In another embodiment of the present invention, as Figure 7 shown, the lower bag sucking assembly 520 includes a set of connecting blocks 521 arranged on the bottom surface of the bearing plate 301. One end of the connecting block 521 away from the bearing plate 301 is connected to a lower sucker mounting plate 522. A plurality of lower vacuum suckers 523 are equidistantly arranged on the lower sucker mounting plate 522. The plurality of lower vacuum suckers 523 adsorb the lower side surface of the packaging bag. When the packaging bag is flipped onto the bearing plate 301, the lower vacuum suckers 523 adsorb the lower side surface of the packaging bag, so that the rotating bag supporting mechanism 600 can quickly open the packaging bag.

[0052] It should be noted that three lower vacuum suckers 523 are provided in this embodiment. The three lower vacuum suckers 523 are distributed on the lower sucker mounting plate 522 and are all connected to a vacuum pumping air source through an air source pipeline. The vacuum pumping air source pumps air to the lower vacuum suckers 523 to generate vacuum adsorption, and then adsorbs the lower side surface of the packaging bag. The installation position of the lower vacuum suckers 523 is adjustable to suit packaging bags of different sizes. The number and installation position of the lower vacuum suckers 523 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 sucking assembly 510 to open the bag mouth of the packaging bag.

[0053] In another embodiment of the present invention, as Figures 8 - 9 shown, the rotating assembly 610 includes a set of second connecting seats 611 connected to the frame 100. A driving motor 612 is arranged on one side of any one of the second connecting seats 611. The output shaft of the driving motor 612 is connected to a rotating shaft 613. The bag supporting assembly 620 is arranged on the rotating shaft 613. The driving motor 612 drives the rotating shaft 613 to rotate. During the rotation of the rotating shaft 613, the bag supporting assembly 620 is driven to rotate towards the pocket direction of the packaging bag. After the bag supporting assembly 620 completes the bag supporting action on the packaging bag, the rotating assembly 610 conveys the opened packaging bag to the next working station.

[0054] In another embodiment of the present invention, as Figures 8 - 9 shown, the bag supporting assembly 620 includes a set of bag supporting connection seats 621 arranged on the rotating shaft 613. A bag supporting member 622 is rotatably connected to each of the two bag supporting connection seats 621. A second connecting member 623 is provided on the inner side wall of each of the two bag supporting members 622. A bag supporting cylinder 624 is connected to one of the second connecting members 623. The output shaft of the bag supporting cylinder 624 is connected to a fourth connecting rod 625. One end of the fourth connecting rod 625 away from the output shaft of the bag supporting cylinder 624 is connected to the other second connecting member 623. The bag supporting member 622 includes a bag supporting plate 626 connected to the bag supporting connection seat 621 and a bag supporting piece 627 arranged below the middle of the bag supporting plate 626. A bag supporting pull rod 628 is connected to the outer surface of each of the two bag supporting plates 626. By driving the fourth connecting rod 625 to move through the bag supporting cylinder 624, the other end of the fourth connecting rod 625 drives the bag supporting member 622 connected to the second connecting member 623 to swing around the bag supporting connection seat 621, so that one bag supporting member 622 approaches or moves away from the other bag supporting member 622, thereby realizing that the bag supporting plate 626 and the bag supporting piece 627 of the bag supporting member 622 open the packaging bag, and making the bag opening of the packaging bag be opened into a flat and long mouth shape.

[0055] The flipping suction bag and supporting device provided by the embodiment of the present invention, as Figures 1 - 9As shown, during use, the first suction bag mechanism 200 moves to the bag-taking station to take a bag. The vacuum suction cup cylinder 202 of the first suction bag mechanism 200 drives the first connecting rod 203 to reciprocate. The other end of the first connecting rod 203 drives the suction cup connecting plate 204 connected to the first rotating shaft 206 to swing around the first rotating shaft 206, thereby driving the vacuum suction cup 205 to swing, so as to perform the operation of adsorbing and taking the packaging bag. After the packaging bag is adsorbed, the bag clamping cylinder 304 of the bag clamping mechanism 300 drives the second connecting rod 305 to move. During the movement of the second connecting rod 305, it drives the clamping jaw 306 to rotate, thereby controlling the closing of the clamping jaw 306, so as to clamp the packaging bag. After the packaging bag is clamped, the turning cylinder 402 of the turning mechanism 400 drives the third connecting rod 403 to move. The other end of the third connecting rod 403 drives the clamping clamp 404 rotatably connected thereto to rotate. The clamping clamp 404 thereby drives the rotating shaft 405 to rotate on the rotating shaft connecting seat 406, and further drives the bearing plate 301 to turn from the vertical state to the horizontal state, so as to turn and convey the packaging bag to the corresponding bag-supporting station. When the packaging bag is turned onto the bearing plate 301, the lower vacuum suction cup 523 of the lower suction bag assembly 520 adsorbs the lower side of the packaging bag, and the upper vacuum suction cup cylinder 512 of the upper suction bag assembly 510 drives the upper suction cup mounting plate 513 to move downward. A plurality of the upper vacuum suction cups 205 on the upper suction cup mounting plate 513 adsorb the upper side of the packaging bag. After a plurality of the upper vacuum suction cups 205 adsorb the upper side of the packaging bag, the upper vacuum suction cup cylinder 512 drives the upper suction cup mounting plate 513 to move upward to open the bag mouth of the packaging bag. At the same time, the driving motor 612 of the rotating assembly 610 drives the rotating shaft 613 to rotate. During the rotation of the rotating shaft 613, it drives the bag-supporting assembly 620 to rotate towards the pocket of the packaging bag. The bag-supporting cylinder 624 of the bag-supporting assembly 620 drives the fourth connecting rod 625 to move. The other end of the fourth connecting rod 625 drives the bag-supporting member 622 connected to the second connecting member 623 to swing around the bag-supporting connecting seat 621, so that one bag-supporting member 622 approaches or moves away from the other bag-supporting member 622, thereby realizing that the bag-supporting plate 626 and the bag-supporting piece 627 of the bag-supporting member 622 expand the packaging bag, so that the bag mouth of the packaging bag is expanded into a flat and long "mouth" shape. After the bag-supporting assembly 620 completes the bag-supporting action on the packaging bag, the rotating assembly 610 conveys the expanded packaging bag to the next station.

[0056] In summary, the flipping suction bag supporting device provided by the embodiment of the present invention, through the cooperation among the first suction bag mechanism 200, the bag clamping mechanism 300, the flipping mechanism 400, the second suction bag mechanism 500 and the rotating bag supporting mechanism 600, the first suction bag mechanism 200 moves to the bag taking station to adsorb the packaging bag on the bag pushing station and cooperates with the bag clamping mechanism 300 to clamp the packaging bag. The flipping mechanism 400 flips the vertically suspended packaging bag from the vertical state to the horizontal state and sends the unopened packaging bag to the corresponding bag supporting station. Then, the two sides of the packaging bag are pulled open by the second suction bag mechanism 500 and cooperate with the rotating bag supporting mechanism 600 to realize the bag supporting operation of the packaging bag, thereby realizing automatic bag suction and bag supporting, reducing the labor intensity and improving the production efficiency.
