[0054] The heat sealing mechanism 800 is provided on the movable frame 200 and is used for heat sealing the bag opening.

[0055] As a supplementary explanation, the present invention is provided with a sensor for sensing the packaging bag.

[0056] The working steps of the present invention are as follows: first, the suction cup mechanism 300 opens the bag opening of the packaging bag, the driving module 400 drives the inner bag sorting mechanism 500 and the outer bag sorting mechanism 600 to approach the packaging bag, the two bag sorting plates 520 of the inner bag sorting mechanism 500 extend into the inner bag, and the two clamping members 620 of the outer bag sorting mechanism 600 clamp the packaging bag, the second translation driving assembly drives the two clamping members 620 to move away from each other to smooth the outer bag from the center to both ends, the first translation driving member 510 drives the two bag sorting plates 520 to move away from each other to flatten the inner bag; then, the vacuum mechanism 700 extracts the air in the bag body; finally, the heat sealing mechanism 800 heat seals the bag opening of the packaging bag.

[0057] It should be noted that the driving module 400 is a motor and a lead screw structure; the first translation driving component 510 and the second translation driving component 610 are both cylinders.

[0059] The movable frame 200 includes an upper movable plate 210, a lower movable plate 220 and multiple second support shafts 230. The two ends of the second support shafts 230 are respectively connected to the upper movable plate 210 and the lower movable plate 220.

The upper fixed plate 110 is sleeved on the second support shaft 230 through a linear bearing 140, that is, the movable frame 200 and the fixed frame 100 are movably connected up and down.

[0060] In this embodiment, the lifting assembly 240 includes a lifting screw 241, a bearing seat 242, and a handwheel 243. The lifting screw 241 is sleeved on the upper fixed plate 110 via a linear bearing 140. The lifting screw 241 is fixedly sleeved on the upper movable plate 210 via the bearing seat 242. The handwheel 243 is connected to one end of the lifting screw 241. When the handwheel 243 is turned, the lifting screw 241 rises and falls relative to the linear bearing 140, that is, the upper movable plate 210 rises and falls relative to the upper fixed plate 110, thereby adjusting the height of the movable frame 200. Therefore, the height of the movable frame 200 can be adjusted according to actual needs, which is more flexible and adaptable.

[0061] In this embodiment, the suction cup mechanism 300 includes a first lifting drive member 310 and two suction cups 320.

The facing sides of the two clamping plates 622 are provided with buffer pads 623. The buffer pads 623 have a buffering effect to prevent the clamping plates 622 from scratching or tearing the packaging bag. The clamping drive member 621 is used to drive the two clamping plates 622 to approach or move away from each other in the vertical direction, thereby clamping or loosening the packaging bag.

[0064] It should be noted that the clamping driving member 621 is a clamping cylinder, and the two clamping plates 622 are connected to the two clamping claws of the clamping cylinder.

[0065] In this embodiment, the vacuum mechanism 700 includes a third translation drive member 710 and a vacuum machine. The vacuum machine is externally arranged.

When the pre-pressing mechanism 900 clamps the bag opening of the packaging bag, it is convenient to remove the exhaust nozzle 720. The exhaust nozzle 720 is arranged on the third translation drive member 710. The third translation drive member 710 is used to drive the exhaust nozzle 720 to move along the X-axis direction.

[0066] In actual operation, the third translation drive member 710 drives the vacuum nozzle 720 to approach and insert into the inner bag. The vacuum machine works to make the vacuum nozzle 720 extract the air from the inner bag. When the inner bag is in a vacuum state, the pre-pressing mechanism 900 clamps the bag opening up and down to prevent air from entering the bag. The end of the vacuum nozzle 720 is set to a flat shape, which also plays a role in cooperating with the bag opening to be clamped.

[0067] It should be noted that the third translation driving member 710 is a cylinder.

[0068] In this embodiment, the heat sealing mechanism 800 includes an upper pressing component 820 and a lower pressing component 810;

[0069] The pressing assembly 810 includes a second lifting member 811 and a lower pad 812. The second lifting member 811 is disposed on the lower movable plate 220. The lower pad 812 is disposed on the second lifting member 811. A first pad 813 is disposed on the top surface of the lower pad 812.

[0071] In actual operation, the second lifting member 811 drives the lower plate 812 to rise, and at the same time the third lifting member 821 drives the cutter 822 to descend. The lower plate 812 and the cutter 822 squeeze the bag opening of the packaging bag, and the cutter 822 heat-seals the bag opening.

[0072] It should be noted that the second lifting member 811 and the third lifting member 821 are both cylinders.

[0073] In this embodiment, the present invention further includes a pre-pressing mechanism 900 , which includes an upper pre-pressing assembly 910 and a lower pre-pressing assembly;

[0076] In actual work, the packaging bag needs to be pre-sealed before heat sealing. The fourth lifting member 911 drives the upper pre-pressing plate 912 to descend, and at the same time the second lifting member 811 drives the lower pre-pressing plate 920 to rise. At this time, the upper pre-pressing plate 912 and the lower pre-pressing plate 920 clamp the packaging bag to prevent air from entering the packaging bag, and at the same time play the role of fixing the bag opening to facilitate the cutter 822 to heat seal the bag opening.
