[0023] It should be noted that the folding packaging box is placed on the conveyor 1 at a regular time by means of a matching automated mechanical suction cup, and the folding packaging box is conveyed between the two conveyor belts by means of the conveyor 1; Start the motor 708, and the power output shaft of the motor 708 drives the reciprocating screw 707 to rotate. The reciprocating screw 707 drives the third rotating shaft 705 to rotate through the first bevel gear 704 and the second bevel gear 706. The third rotating shaft 705 drives the first rotating shaft 603 to rotate through the third pulley 703, the second pulley 701, and the second connecting belt 702. The first rotating shaft 603 drives the driving roller 609 to rotate, and the driving roller 609 drives the driving belt 607 to transmit. When the first rotating shaft 603 rotates, it will also drive the first gear 602 to rotate. The first gear 602 will drive the other first gear 602 to rotate in the opposite direction, so that the other driving belt 607 can drive in the opposite direction. In this way, the two driving belts 607 can further transport the folding packaging box transported by the conveyor 1, and because the spacing between the two driving belts 607 is limited, the folding packaging box will be further squeezed when it is transported.

[0024] Please refer to Figures 5 to 7A slide groove 611 is provided on the inner wall of the mounting frame 601, a second slide bar 612 is fixedly installed inside the slide groove 611, a positioning block 615 is fixedly connected to the second slide bar 612, a second spring 616 is fixedly connected to the top and bottom of the positioning block 615, a slider 614 is fixedly connected to the second spring 616, and the slider 614 is slidably connected to the mounting frame 601 and the second slide bar 612; a second pressing plate 610 is fixedly connected to the slider 614, and an auxiliary stick 613 is rotatably connected to the second pressing plate 610. The intermittent pressing mechanism includes a driving box 901, and the driving box 901 is located at the driving box The belt 607 is fixedly connected to the mounting frame 601, the driving box 901 is slidably connected with a piston plate 904, the piston plate 904 is fixedly connected with a pressure rod 902, the pressure rod 902 penetrates the driving box 901 and is slidably connected to the driving box 901, and a third spring 903 is sleeved on the pressure rod 902, and the two ends of the third spring 903 are respectively connected to the piston plate 904 and the driving box 901; the driving box 901 is fixedly connected with an air guide pipe 905, and the air guide pipe 905 is fixedly connected with an air delivery pipe 906, which extends to the inside of the slide groove 611, and the air delivery pipe 906 is slidably connected inside. The third spring 903 is connected to the gas pipe 906 through the fourth spring 907. The intermittent pressing mechanism also includes a first protrusion 606, which is located between the two driving rollers 609 and is fixedly connected to the second rotating shaft 608. When the first rotating shaft 603 rotates, it will also drive the first protrusion 606 to rotate. The rotation of the first protrusion 606 will squeeze the pressure rod 902, and the pressure rod 902 will drive the piston plate 904 to move, so that the gas in the piston plate 904 is transported to the gas pipe 906 through the air guide pipe 905. Due to the entry of gas, under the action of air pressure, When the second pressing plate 610 is pressed downward, the third sliding bar 908 can be prompted to move, and the movement of the third sliding bar 908 will act on the slider 614 to move the slider 614, and the movement of the slider 614 will drive the second pressing plate 610 to move, and the second pressing plate 610 pressing downward will act on the conveyor belt. Since the two second pressing plates 610 are operated synchronously, approaching or moving away from each other, when the two second pressing plates 610 are close to each other, the gap between the two driving belts 607 will be reduced, thereby achieving the effect of squeezing the folded packaging box, and the operation is fast, and the small wrinkles on the surface of the folded packaging box can be effectively smoothed by quick pressing.

[0025] Please refer to Figure 3 to Figure 4, a first double-axis pulley 710 is fixedly connected to the third rotating shaft 705, and two adjacent first double-axis pulleys 710 are connected by a third connecting belt 711; a second protrusion 712 is arranged inside the driving belt 607, and the second protrusion 712 is fixedly connected to the third rotating shaft 705; when the third rotating shaft 705 rotates, it will also drive the second protrusion 712 to rotate, and the rotation of the second protrusion 712 will squeeze the second pressing plate 610, so that the second pressing plate 610 slowly moves down, and when the second protrusion 712 squeezes the second pressing plate 610 to move down to the critical point, it will deeply squeeze the driving belt 607, so that the driving belt 607 compresses the folding packaging box, so that the folding of the folding packaging box can be repaired more deeply and thoroughly with the help of a single slow pressing, and the rotation of the third rotating shaft 705 will also drive multiple third rotating shafts 705 to rotate through the first double-axis pulley 710 and the third connecting belt 711, thereby driving multiple second pressing plates 610 to run synchronously.

[0026] like Figure 2 , Fig.11 As shown, a flip mechanism is fixedly connected to the support plate 2, and the flip mechanism includes a fixed shaft 805, the fixed shaft 805 is fixedly connected to the support plate 2, a rotating ring 812 is fixedly connected to the fixed shaft 805, a rotating block 804 is rotatably connected to the rotating ring 812, and the rotating block 804 is fixedly connected to the mounting frame 601; the flip mechanism also includes a first connecting frame 803, the first connecting frame 803 is fixedly connected to the threaded plate 801, a first extension plate 802 is fixedly connected to the first connecting frame 803, a rack 810 is fixedly connected to the first extension plate 802, and a second extension plate 811 is fixedly connected to the rack 810; the flip mechanism also includes a worm 809, a rotating seat 808 is rotatably connected to the worm 809, the rotating seat 808 is fixedly connected to the mounting frame 601, a worm wheel 807 is meshed on the worm 809, the worm wheel 807 is fixedly connected to the fixed shaft 805, and a second gear 806 is fixedly connected to the worm 809.

[0027] It should be noted that when the reciprocating screw rod 707 rotates, the threaded plate 801 will also reciprocate, and the reciprocating movement of the threaded plate 801 will cause the first connecting frame 803 to reciprocate, and the reciprocating movement of the first connecting frame 803 will drive the first extension plate 802, the second extension plate 811, and the rack 810 to reciprocate; In this way, when the motor 708 is started, the motor 708 drives the driving belt 607 to squeeze and convey the folding packaging box, and the rack 810 will continue to approach the second gear 806. When the driving belt 607 has stored all the folding packaging boxes between the two driving belts 607, the rack 810 will also begin to act on the second gear 806 to rotate the second gear 806, and the second gear 806 drives the worm 809 to rotate, and the worm 809 will rotate around the worm wheel 807, so that the rotating block 804 rotates around the rotating ring 812, so that the driving belt 607 located above will turn over. When the rack 810 completely acts on the second gear 806, the rotating block 804 just rotates 180 degrees. At this time, due to the action of the first extension plate 802, the driving belt 607 will continue to run, and the driving block will not turn over, so that the driving belt 607 can transport the folding packaging box to the packaging storage box 4 for packaging, and the folding packaging box will turn over during the process, which can be conveniently used for double-sided inspection to avoid packaging damaged folding packaging boxes.

[0028] like Fig.12 As shown, a packaging mechanism is fixedly installed on the fixed shaft 805, and the packaging mechanism includes a support frame 501, the support frame 501 is fixedly connected to the fixed shaft 805, and the support frame 501 is fixedly connected to the bottom plate 3; a first slide bar 505 is fixedly connected to the support frame 501, the first slide bar 505 is fixedly connected to the bottom plate 3, a slide plate 503 is slidably connected to the first slide bar 505, and the slide plate 503 is connected to the bottom plate 3 through a first spring 504, a second connecting frame 507 is fixedly connected to the slide plate 503, and the second connecting frame 507 is fixedly connected to the first pressing plate 506, a packaging storage box 4 is arranged below the first pressing plate 506, and the packaging storage box 4 is fixed on the bottom plate 3; two first magnetic blocks 502 are fixedly installed on the rotating block 804, and a second magnetic block 508 is fixedly connected to the second connecting frame 507, and the first magnetic block 502 and the second magnetic block 508 magnetically repel each other.

[0029] It should be noted that, during the rotation of the rotating block 804, the first magnetic block 502 will also be driven to rotate. When it rotates ninety degrees, the first magnetic block 502 will act on the second magnetic block 508, so that the second connecting frame 507 drives the first pressure plate 506 to move downward. The downward movement of the first pressure plate 506 will squeeze the folding packaging box in the packaging storage box 4. Since the folding packaging box in the packaging storage box 4 is placed on the reverse side, by alternately pressing on the front and back sides, pressure can be applied to the folds of the paper box from different directions, so that all parts of the paper box can be fully adjusted.

[0030] like Fig.13 As shown, a packaging method of a packaging box automatic packaging device includes the following steps: S1: conveying: conveying the folded packaging box by the conveyor 1 fixed on the support plate 2, so that the folded packaging box enters between the two driving belts 607; S2: first pressing: start the motor 708, and control the second pressing plate 610 to press the folding packaging box through the motor 708; S3: Flipping: The motor (708) is used to control the worm (809) to flip around the worm wheel (807).
