The bag suction device 300 comprises a first suction assembly 310 and a second suction assembly 330, the first suction assembly 310 is used for suctioning the packaging bags 630 located in the temporary storage device 100 and transferring the packaging bags 630 to the conveying device 200, and the first suction assembly 310 and the second suction assembly 330 can cooperate to open the bag opening of the packaging bags 630. The discharging device 400 is located above the conveying device 200. The sealing device 420 is located above the conveying device 200. The bag clamping device 500 is used for clamping the bag opening of the packaging bags 630 to align the bag opening of the packaging bags 630 with the discharging port 410 of the discharging device 400, the discharging device 400 is used for transferring the material into the packaging bags 630, the conveying device 200 is used for conveying the packaging bags 630 filled with the material to the sealing device 420, and the sealing device 420 is used for sealing the packaging bags 630.

[0044] It can be understood that when the automatic filling and sealing bag packaging machine starts to work, the first suction assembly 310 sucks and transfers the packaging bag 630 on the temporary storage device 100 to the conveying device 200, the first suction assembly 310 and the second suction assembly 330 cooperate to open the bag opening of the packaging bag 630, the bag clamping device 500 clamps the packaging bag 630 so as to keep the bag opening of the packaging bag 630 continuously open and aligned with the discharging opening 410 of the discharging device 400, the material of the discharging device 400 enters the packaging bag 630 through the discharging opening 410, and the conveying device 200 conveys the packaging bag 630 to the sealing device 420 for sealing treatment; the automatic filling and sealing bag packaging machine can realize fully automatic production of filling and sealing, avoids the need for manual intervention, and improves production efficiency.

[0045] According to some embodiments of the present application, referring to Figure 1 and Figure 3 , the conveying device 200 can convey the packaging bag 630 from right to left, the temporary storage device 100 is located at the rear side of the conveying device 200, the temporary storage device 100 includes a temporary storage cabinet 110, a push plate 120 and a first driving component 130, and the push plate 120 is arranged in the temporary storage cabinet 110; in the temporary storage cabinet 110, a plurality of packaging bags 630 are stacked in the front-rear direction with the bag openings upward, and the first driving component 130 is used to drive the push plate 120 to move in the front-rear direction, so that the push plate 120 can push the plurality of packaging bags 630 to move forward. The first suction assembly 310 can suck and transfer the packaging bag 630 located at the frontmost position on the temporary storage device 100 to the conveying device 200.

[0046] Preferably, referring to Figure 3The first driving component 130 comprises a first driving motor 131, a first rack 132 and a first gear 133. The first driving motor 131 is installed on the push plate 120 which is slidingly connected to the temporary storage cabinet 110 in the front-rear direction. The first rack 132 is arranged on the temporary storage cabinet 110 and extends in the front-rear direction.

The rear side surface of the stopper 140 can abut against the packaging bag 630 located at the frontmost position of the temporary storage device 100. It can be understood that when the first suction assembly 310 sucks the packaging bag 630 located at the frontmost position of the temporary storage device 100, the stopper 140 can provide a certain resistance to the packaging bag 630 at the frontmost position. The first suction assembly 310 overcomes the resistance of the stopper 140 and thus sucks away the packaging bag 630 at the frontmost position. Since the second packaging bag 630 has a certain adsorption force with the packaging bag 630 at the frontmost position, after the packaging bag 630 at the frontmost position is sucked away, the stopper 140 can immediately block the second packaging bag 630 located at the second position from moving forward, so as to avoid that the packaging bag 630 is separated from the temporary storage cabinet 110.

[0047] According to some embodiments of the present application, with reference to Figure 1 and Figure 2 , the conveying device 200 comprises a first conveying assembly 210, a second conveying assembly 220 and a first lifting assembly 230.

The first conveying assembly 210 can transport the packaging bag 630 to the second conveying assembly 220. The second conveying assembly 220 can transport the packaging bag 630 to the sealing device 420. The first conveying assembly 210 and the second conveying assembly 220 are both belt conveying assemblies. The first lifting assembly 230 is a lifting cylinder. It can be understood that when the packaging bag 630 is located on the first conveying assembly 210, the first lifting assembly 230 can drive the first conveying assembly 210 to move in the up-down direction, thereby driving the packaging bag 630 to move in the up-down direction, so as to adapt to packaging bags 630 of different heights. The bag opening of the packaging bag 630 can be aligned with the dispensing opening 410 of the dispensing device 400 and kept at a small distance from the dispensing opening 410, so as to avoid that the distance is too large and the material is scattered around. Moreover, the first lifting assembly 230 can cooperate with the bag clamping device 500 to ensure that the bag clamping device 500 can clamp the side wall of the packaging bag 630.

[0048] According to some embodiments of the present application, with reference to Figure 4 and Figure 5, the automatic loading and bag sealing and packing machine further comprises a frame 600, the first suction assembly 310 comprises a first suction disc 311 and a second driving component 312, the first suction disc 311 is located at the front side of the temporary storage device 100, the second driving component 312 comprises a second driving motor 321 and a rotating motor 322, the rotating motor 322 can drive the first suction disc 311 to rotate so that the suction port of the first suction disc 311 faces forward or backward, the rotating motor 322 is slidingly connected to the frame 600 in the front-rear direction, and the second driving motor 321 can drive the rotating motor 322 to move in the front-rear direction.

[0049] It can be understood that when the packaging bag 630 on the temporary storage device 100 needs to be sucked, the rotating motor 322 drives the first suction disc 311 to rotate so that the suction port of the first suction disc 311 faces backward, the second driving motor 321 drives the rotating motor 322 and the first suction disc 311 to move backward so that the first suction disc 311 can abut and adsorb the packaging bag 630, the second driving motor 321 drives the rotating motor 322 and the first suction disc 311 to move forward again so that the first suction disc 311 carries the packaging bag 630 to move forward, the rotating motor 322 drives the first suction disc 311 to rotate again so that the packaging bag 630 falls on the first conveying assembly 210 of the conveying device 200, and the third driving component 332 drives the second suction disc 331 to move forward again so that the second suction disc 331 adsorbs the front side of the packaging bag 630.

At this time, the bag opening is aligned with the discharging port 410.

[0050] Preferably, referring to Figure 4 , the discharging port 410 of the discharging device 400 is in a strip shape and extends in the left-right direction. It can be understood that during the movement of the packaging bag 630 filled with material from right to left, a flat part 631 extending in the left-right direction and a sewing thread in the left-right direction will appear on the packaging bag 630 after the sealing by the sealing device 420. The extension of the discharging port 410 in the left-right direction can make the material in the packaging bag 630 extend and distribute in the left-right direction and gradually accumulate upward during the filling process, that is, the length of the material in the packaging bag 630 in the left-right direction is greater than the length in the front-rear direction, so as to facilitate the subsequent sewing and sealing treatment of the sealing device 420 in the left-right direction, and avoid the sewing deviation due to the uneven distribution of the weight of the material in the packaging bag 630 in the left-right direction.

[0051] According to some embodiments of the present application, referring to Figure 4 and Figure 5 , the automatic loading and bag sealing and packing machine further comprises a frame 600 and a second lifting assembly 610, the bag clamping device 500 comprises a lifting frame 510 and two bag clamping assemblies 520 symmetrically arranged along the front-rear direction, the lifting frame 510 is slidingly connected to the frame 600, the second lifting assembly 610 is used to drive the lifting frame 510 to move along the up-down direction, the bag clamping assembly 520 comprises a bag clamping cylinder 521, a fixed clamping arm 522 and a movable clamping arm 523, one end of the fixed clamping arm 522 is fixedly connected to the lifting frame 510, the middle part of the movable clamping arm 523 is rotatably connected to the fixed clamping arm 522, and the bag clamping cylinder 521 is installed on the fixed clamping arm 522. The driving end of the bag clamping cylinder 521 is connected to one end of the movable clamping arm 523, and the bag clamping cylinder 521 can drive the movable clamping arm 523 to rotate to make the movable clamping arm 523 and the fixed clamping arm 522 cooperate to clamp the side wall of the packaging bag 630. It can be understood that the two bag clamping assemblies 520 can clamp the front and rear side walls of the packaging bag 630 respectively, so that the bag opening of the packaging bag 630 remains open, avoiding the bag opening of the packaging bag 630 from being reduced during the loading process, causing the material to spill. The second lifting assembly 610 can drive the lifting frame 510 and the bag clamping assembly 520 to move along the up-down direction, so that the bag clamping assembly 520 can adapt to packaging bags 630 of different heights. The second lifting assembly 610 comprises a lifting motor, a second rack and a second gear. The second rack is installed on the frame 600 and extends along the up-down direction. The driving end of the lifting motor is fixedly connected to the second gear, and the second gear is meshingly connected to the second rack. The lifting motor is slidingly connected to the frame 600, and the lifting motor is fixedly installed on the lifting frame 510. The rotation of the lifting motor can make the second gear and the second rack move relatively, thereby driving the lifting frame 510 to move along the up-down direction.

[0052] According to some embodiments of the present application, referring to Figure 6 , the second conveying assembly 220 is provided with a guide plate 620 near one end of the first conveying assembly 210. Two guide plates 620 are arranged at intervals along the front-rear direction, and a guide channel is formed between the two guide plates 620. The two guide plates 620 cooperate to guide the packaging bag 630 on the second conveying assembly 220 to move along a specified path. After the packaging bag 630 moves from the first conveying assembly 210 to the second conveying assembly 220, the packaging bag 630 enters the guide channel. The guide channel extends along the left-right direction, and the two guide plates 620 can respectively exert forward and rearward forces on the packaging bag 630, thereby adjusting the distribution of the material in the packaging bag 630, so that the material in the packaging bag 630 extends along the left-right direction, avoiding the center of gravity of the packaging bag 630 from being biased forward or backward, causing the packaging bag 630 to be separated from the second conveying assembly 220 along the front-rear direction. The guide plate 620 can ensure that the packaging bag 630 can smoothly pass through the sealing device 420 for sealing treatment, improving the yield.

[0053] According to some embodiments of the present application, with reference to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , the automatic loading, bag sealing and packing machine further comprises a guiding device 700 located on the left side of the guiding plate 620, the guiding device 700 is located above the second conveying assembly 220, the guiding device 700 comprises, from right to left, a first bag pressing device 710, a second bag pressing device 720 and a third bag pressing device 730.

[0054] The first bag pressing device 710 can press the upper ends of the front and rear sidewalls of the packaging bag 630 to form a flat part 631, so that the bag opening of the packaging bag 630 is closed, and the first bag pressing device 710 can press the flat part 631 and transport the packaging bag 630 to the second bag pressing device 720. The first bag pressing device 710 comprises two first bag pressing assemblies 711 symmetrically arranged in the front-rear direction, each first bag pressing assembly 711 comprises a first belt assembly 712 and an oscillating cylinder 713, and the oscillating cylinder 713 is used to drive the first belt assembly 712 to oscillate. In the two first bag pressing assemblies 711, the two oscillating cylinders 713 can respectively drive the two first belt assemblies 712 to oscillate so that the two first belt assemblies 712 move away from or close to each other, and the two first belt assemblies 712 can jointly press the flat part 631 and transport the packaging bag 630 to the left. It can be understood that when the packaging bag 630 passes through the first bag pressing device 710, the oscillating cylinder 713 drives the first belt assembly 712 to oscillate, so that the two first belt assemblies 712 move close to each other and abut and press the front and rear sides of the packaging bag 630, so that the bag opening of the packaging bag 630 is closed, the upper end of the packaging bag 630 is pressed to form the flat part 631, and the flat part 631 extends in the left-right direction. The belt of the first belt assembly 712 drives the packaging bag 630 to move from right to left during rotation.

[0055] The second bag pressing device 720 can receive and press the flat part 631 of the packaging bag 630 from the first bag pressing device 710 and drive the flat part 631 to move upward and to the left. The second bag pressing device 720 comprises two second belt assemblies 721 symmetrically arranged in the front-rear direction, the belt conveying direction of the second belt assembly 721 is upward and to the left, and the right end of the second belt assembly 721 is lower than the left end of the second belt assembly 721. The belt of the second belt assembly 721 drives the flat part 631 of the packaging bag 630 to move upward and to the left during rotation. It can be understood that during the movement of the flat part 631 to the left and upward by the second belt assembly 721, the bottom of the packaging bag 630 does not separate from the second conveying assembly 220, i.e. the second conveying assembly 220 supports the packaging bag 630, and the packaging bag 630 is pulled upward by the two second belt assemblies 721, so that the packaging bag 630 is straightened to facilitate the smoothness of the flat part 631 without wrinkles, and facilitate subsequent sewing and sealing.
