[0042] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0043] According to some embodiments of the present invention, referring to Figures 1 to 7 The automatic loading and sealing packaging machine includes a temporary storage device 100, a conveying device 200, a bag suction device 300, a feeding device 400, a sealing device 420 and a bag clamping device 500. The temporary storage device 100 is used to temporarily store a plurality of packaging bags 630. The bag suction device 300 includes a first suction component 310 and a second suction component 330. The first suction component 310 is used to suck the packaging bag 630 located in the temporary storage device 100 and transfer the packaging bag 630 to the conveying device 200. The first suction component 310 and the second suction component 330 can cooperate to open the bag mouth of the packaging bag 630. The feeding 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 to clamp the bag opening of the packaging bag 630 so that the bag opening of the packaging bag 630 is aligned with the unloading port 410 of the unloading device 400. The unloading device 400 is used to transfer the material into the packaging bag 630. The conveying device 200 is used to convey the packaging bag 630 containing the material to the sealing device 420. The sealing device 420 is used to seal the packaging bag 630.

[0044] It can be understood that when the automatic loading, bag sealing and baling machine is started, the first suction component 310 absorbs the packaging bag 630 located on the temporary storage device 100 and transfers it to the conveying device 200, the first suction component 310 and the second suction component 330 cooperate to open the bag opening of the packaging bag 630, the bag clamping device 500 clamps the packaging bag 630 to keep the bag opening of the packaging bag 630 continuously open and aligned with the discharge port 410 of the discharge device 400, the material of the discharge device 400 enters the packaging bag 630 through the discharge port 410, and the conveying device 200 then transports the packaging bag 630 to the sealing device 420 for sealing; the automatic loading, bag sealing and baling machine can realize fully automated production of loading and sealing, avoid the need for manual intervention, and improve production efficiency.

[0045] According to some embodiments of the present invention, 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. The push plate 120 is arranged in the temporary storage cabinet 110. In the temporary storage cabinet 110, multiple packaging bags 630 are stacked in the front-to-back direction with the bag opening facing upward. The first driving component 130 is used to drive the push plate 120 to move in the front-to-back direction, so that the push plate 120 can push the multiple packaging bags 630 to move forward. The first suction component 310 can absorb the packaging bag 630 located at the front of the temporary storage device 100 and transfer it to the conveying device 200.

[0046] Preferably, refer to Figure 3The first driving component 130 includes 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, and the push plate 120 is slidably connected to the temporary storage cabinet 110 along the front-to-back direction. The first rack 132 is provided on the temporary storage cabinet 110 and extends along the front-to-back direction. The driving end of the first driving motor 131 is fixedly connected to the first gear 133, and the first gear 133 is meshedly connected to the first rack 132. The left inner wall and the right inner wall of the temporary storage cabinet 110 are both provided with a plurality of blocks 140, and the rear side of the block 140 can abut against the packaging bag 630 located at the front of the temporary storage device 100. It can be understood that when the first suction component 310 sucks the packaging bag 630 located at the front of the temporary storage device 100, the block 140 can provide a certain resistance to the packaging bag 630 at the front, and the first suction component 310 overcomes the resistance of the block 140 to suck away the packaging bag 630 at the front, and because there is a certain adsorption force between the second packaging bag 630 and the packaging bag 630 at the front, after the packaging bag 630 at the front is sucked away, the block 140 can immediately block the second packaging bag 630 from the front to the back located in the temporary storage device 100 from moving forward, thereby preventing the packaging bag 630 from leaving the temporary storage cabinet 110.

[0047] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The conveying device 200 includes a first conveying assembly 210, a second conveying assembly 220 and a first lifting assembly 230. The first conveying assembly 210 is located directly below the unloading device 400. The first lifting assembly 230 is used to drive the first conveying assembly 210 to move in the up and down direction. The second conveying assembly 220 is located on the left side of the first conveying assembly 210. The first conveying assembly 210 can transport the packaging bag 630 to the second conveying assembly 220, and 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, and the first lifting assembly 230 is a lifting cylinder. It is understandable 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, so that the bag opening of the packaging bag 630 can be aligned with the discharge opening 410 of the discharge device 400 and the distance between the bag opening 410 and the discharge opening 410 is kept at a small distance, so as to avoid the material spilling around due to the large distance. In addition, 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 invention, referring to Figure 4 and Figure 5The automatic loading and sealing packaging machine also includes a frame 600, a first suction assembly 310 includes a first suction cup 311 and a second driving component 312, the first suction cup 311 is located at the front side of the temporary storage device 100, and the second driving component 312 includes a second driving motor 321 and a rotating motor 322, the rotating motor 322 can drive the first suction cup 311 to rotate so that the suction port of the first suction cup 311 faces forward or backward, the rotating motor 322 is slidably connected to the frame 600 along the front-to-back direction, and the second driving motor 321 can drive the rotating motor 322 to move along the front-to-back direction. The second suction assembly 330 includes a second suction cup 331 and a third driving component 332, the second suction cup 331 is located at the front side of the first suction cup 311, the suction port of the second suction cup 331 faces backward, the second suction cup 331 is slidably connected to the frame 600 along the front-to-back direction, and the third driving component 332 can drive the second suction cup 331 to move along the front-to-back direction.

[0049] It can be understood that when it is necessary to suck the packaging bag 630 on the temporary storage device 100, the rotating motor 322 drives the first suction cup 311 to rotate so that the suction port of the first suction cup 311 faces backward, the second driving motor 321 drives the rotating motor 322 and the first suction cup 311 to move backward so that the first suction cup 311 can abut and absorb the packaging bag 630, and the second driving motor 321 drives the rotating motor 322 and the first suction cup 311 to move forward so that the first suction cup 311 moves forward with the packaging bag 630, and the rotating motor 322 drives the first suction cup 311 to move forward. The motor 322 then drives the first suction cup 311 to rotate so that the packaging bag 630 falls onto the first conveying assembly 210 of the conveying device 200, and the third driving component 332 then drives the second suction cup 331 to move forward so that the second suction cup 331 absorbs the front side of the packaging bag 630. At this time, the first suction cup 311 is absorbing the rear side of the packaging bag 630. The second driving motor 321 and the third driving component 332 cooperate to make the first suction cup 311 and the second suction cup 331 move away from each other, thereby opening the bag opening of the packaging bag 630. At this time, the bag opening is aligned with the discharge port 410.

[0050] Preferably, refer to Figure 4 , the feeding opening 410 of the feeding device 400 is in the shape of a long strip and extends in the left-right direction. It is understandable that when the packaging bag 630 filled with materials moves from right to left, after being sealed by the sealing device 420, a flat portion 631 extending in the left-right direction and a sewing thread extending in the left-right direction will appear on the packaging bag 630. The extension of the feeding opening 410 in the left-right direction enables the materials in the packaging bag 630 to extend and distribute in the left-right direction and gradually accumulate upward during the loading process, that is, the length of the materials in the packaging bag 630 in the left-right direction is greater than the length in the front-back direction, so that the sealing device 420 can perform sewing and sealing processing in the left-right direction later, and avoid sewing deviation due to uneven distribution of the weight of the materials in the packaging bag 630 in the left-right direction.

[0051] According to some embodiments of the present invention, referring to Figure 4 and Figure 5 The automatic loading, bag sealing and baling machine also includes a frame 600 and a second lifting assembly 610. The bag clamping device 500 includes a lifting frame 510 and two bag clamping assemblies 520 symmetrically arranged along the front-to-back direction. The lifting frame 510 is slidably connected to the frame 600. The second lifting assembly 610 is used to drive the lifting frame 510 to move in the up and down directions. The bag clamping assembly 520 includes 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, and the middle part of the movable clamping arm 523 is rotatably connected to the fixed clamping arm 522. The bag clamping cylinder 521 is installed on the fixed clamping arm 522, and the driving end of the bag clamping cylinder 521 is connected to one end of the movable clamping arm 523. The bag clamping cylinder 521 can drive the movable clamping arm 523 to rotate so that 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 respectively clamp the front and rear side walls of the packaging bag 630, so that the bag opening of the packaging bag 630 is continuously opened, so as to prevent the bag opening of the packaging bag 630 from shrinking during the loading process and causing the material to spill. The second lifting assembly 610 can drive the lifting frame 510 and the bag clamping assembly 520 to move in the up and down direction so that the bag clamping assembly 520 can adapt to packaging bags 630 of different heights. The second lifting assembly 610 includes a lifting motor, a second rack and a second gear. The second rack is mounted on the frame 600 and extends in the up and down direction. The driving end of the lifting motor is fixedly connected to the second gear, and the second gear is meshed with the second rack. The lifting motor is slidably connected to the frame 600. The lifting motor is fixedly mounted on the lifting frame 510. The rotation of the lifting motor can make the second gear and the second rack move relative to each other, thereby driving the lifting frame 510 to move in the up and down direction.

[0052] According to some embodiments of the present invention, referring to Figure 6 A guide plate 620 is provided at one end of the second conveying assembly 220 close to the first conveying assembly 210. The two guide plates 620 are arranged at intervals in the front-to-back direction. A guide channel is formed between the two guide plates 620. The two guide plates 620 cooperate to guide the packaging bag 630 located 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 in the left-right direction. The two guide plates 620 can respectively apply forward and backward forces to the packaging bag 630, thereby adjusting the distribution of materials in the packaging bag 630 so that the materials in the packaging bag 630 extend in the left-to-right direction, thereby preventing the center of gravity of the packaging bag 630 from being biased forward or backward and causing it to separate from the second conveying assembly 220 in the front-to-back direction. The guide plates 620 can ensure that the packaging bag 630 can smoothly pass through the sealing device 420 for sealing processing, thereby improving the yield rate.

[0053] According to some embodiments of the present invention, referring to Figure 1 , Figure 2 , Figure 6 and Figure 7 The automatic loading, bag sealing and packaging machine also includes a guide device 700, which is located on the left side of the guide plate 620. The guide device 700 is located above the second conveying component 220. The guide device 700 includes a first bag pressing device 710, a second bag pressing device 720 and a third bag pressing device 730 from right to left.

[0054] The first bag pressing device 710 can press the upper ends of the front and rear side walls of the packaging bag 630 to form a flat portion 631, so that the bag mouth of the packaging bag 630 is closed. The first bag pressing device 710 can press the flat portion 631 and transport the packaging bag 630 to the second bag pressing device 720. The first bag pressing device 710 includes two first bag pressing assemblies 711 symmetrically arranged along the front and rear directions. The first bag pressing assembly 711 includes a first belt assembly 712 and a swing cylinder 713. The swing cylinder 713 is used to drive the first belt assembly 712 to swing. In the two first bag pressing assemblies 711, the two swing cylinders 713 can respectively drive the two first belt assemblies 712 to swing so that the two first belt assemblies 712 are away from or close to each other. The two first belt assemblies 712 can work together to press the flat portion 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 swing cylinder 713 drives the first belt assembly 712 to swing, so that the two first belt assemblies 712 approach each other and abut and press the front and rear sides of the packaging bag 630, so that the bag mouth of the packaging bag 630 is closed, and the upper end of the packaging bag 630 is pressed to form a flat portion 631, and the flat portion 631 extends in the left and right directions. The belt of the first belt assembly 712 drives the packaging bag 630 to move from right to left during the rotation process.

[0055] The second bag pressing device 720 can receive and press the flat portion 631 of the packaging bag 630 from the first bag pressing device 710 and drive the flat portion 631 to move along the upper left. The second bag pressing device 720 includes two second belt assemblies 721 symmetrically arranged along the front-to-back direction, the belt conveying direction of the second belt assembly 721 is toward the upper 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 portion 631 of the packaging bag 630 to move toward the upper left during the rotation process.
