[0021] Preferably, the servo feeding mechanism 8 includes a transmission belt 801 spanning the second conveying mechanism 5 and the first conveying mechanism 2, and a servo motor 803 for driving the transmission belt 801 to operate. A push plate 802 is installed on the transmission belt 801. The running direction of the transmission belt 801 is perpendicular to the running direction of the second conveying mechanism 5 and the first conveying mechanism 2. A guide groove 804 is provided between the second conveying mechanism 5 and the first conveying mechanism 2 to adapt to the transmission belt 801.

[0022] Preferably, the second conveying mechanism 5 includes push blocks 502 evenly distributed on the middle conveyor belt 501, first pressure strips 503 provided on both sides of the push blocks 502, and second pressure strips 504 provided above the push blocks 502. The length direction of the first pressure strips 503 and the second pressure strips 504 is consistent with the running direction of the middle conveyor belt 501. Figure 2 、 Figure 3 and Figure 5 Here, there are two first pressure strips 503 arranged on both sides of the push block 502, and the second pressure strip 504 is located above the push block 502. Specifically, the first pressure strip 503 and the second pressure strip 504 are arranged on both sides below the transmission belt 801, that is, according to the running direction of the conveyor belt 501, the second pressure strip 504 is located behind the first pressure strip 503.

[0023] Preferably, the crease pressing mechanism 10 includes a pair of folding guide plates 1001 arranged on both sides of the middle conveyor belt 501 and located at the end of the second pressure strip 504. The front ends of the two folding guide plates 1001 form a trumpet-shaped guiding surface inclined forward and upward. Figure 2, here the trumpet-shaped guide surface and the second pressure strip 504 have an overlapping area. When the paper sheet advances with the middle conveyor belt 501, the paper bodies on both sides of the paper sheet gradually stand up vertically along the trumpet-shaped guide surface and wrap the bottom and two side surfaces of the packaging box 14. In this way, when the paper body stands up, the limiting effect of the second pressure strip 504 prevents the packaging box 14 from being lifted and shifted to ensure a stable position. A first paper folding pressing plate 506 is provided above the folding guide plate 1001. A first paper folding guide rod 505 is provided at the front end of the first paper folding pressing plate 506. The first paper folding guide rod 505 is located above the trumpet-shaped guide surface and is inclined outward to fold the upright rear side paper body toward the upper surface of the packaging box 14. Please refer to Figure 2 The front end of the first paper folding guide rod 505 is inclined toward a folding guide plate 1001 on the rear side and intersects with a folding guide plate 1001 on the rear side at the middle position above the trumpet-shaped guide surface. In this way, after the paper body on the rear side of the paper sheet is erected, when it continues to move forward with the intermediate conveyor belt 501, the paper body is bent toward the upper surface of the packaging box 14 by the action of the first paper folding guide rod 505 and adhered to the upper surface of the packaging box 14 under the action of the first paper folding pressing plate 506. There is a gap between the two sides of the first paper folding pressing plate 506 and the two folding guide plates 1001. In this way, on the one hand, the paper body after being erected on the front side moves forward in an upright state, and on the other hand, it is convenient to spray glue on the bent rear paper body; A second folding guide rod 507 is provided at the outlet end of a folding pressure plate 506. The second folding guide rod 507 is provided on the opposite side of the first folding guide rod 505, and is used to fold the upright front paper body toward the upper surface of the packaging box 14 and overlap with the upper surface of the rear paper body. Here, the front end of the first folding guide rod 505 also has a guiding section with a folding guide plate 1001 inclined toward the front side and a pressing section located above the middle of the middle conveyor belt 501. That is, when the paper sheet and the packaging box 14 move forward along the middle conveyor belt 501, the upright front paper body is gradually folded toward the upper surface of the packaging box 14 under the action of the guiding section, and finally, under the action of the pressing section, it is adhered and overlapped on the upper surface of the rear paper body to complete the wrapping of the packaging box 14.

[0024] Preferably, the multifunctional automatic wrapping machine also includes a glue nozzle 15 for spraying glue at a set position on the surface of the rear side paper body that is bent and adhered to the upper surface of the packaging box 14 so that the front side paper body and the upper surface of the rear side paper body are bonded together when they overlap. Specifically, the glue nozzle 15 is installed above the first folding paper pressing plate 506, and it sprays glue toward the rear side paper body that has been bent and adhered to the upper surface of the packaging box 14 through the gap between the first folding paper pressing plate 506 and a folding guide plate 1001 on the rear side.

[0025] Preferably, an instruction manual scanning sensor 9 and a paper box scanning sensor 11 are also provided above the intermediate conveyor belt 501. The instruction manual scanning sensor 9 is provided on the front side of the servo feeding mechanism 8 for scanning the instruction manual, and the paper box scanning sensor 11 is provided at the output end of the fold pressing mechanism 10 for scanning the wrapped packaging box 14.

[0026] Preferably, a rejection mechanism 12 is provided at the end of the second conveying mechanism 5, including a collection frame 1201 provided on one side of the intermediate conveyor belt 501 and a cylinder 1203 on the other side. A waste pushing head 1202 is installed at the output end of the cylinder 1203 for pushing defective products on the intermediate conveyor belt 501 into the collection frame 1201.

[0027] Combine Figures 1 to 4 The working principle of the present invention is that the wrapping paper and the instruction manual are placed in the paper material bin 3 and the instruction manual bin 6 respectively, and the packaging box 14 with the materials loaded is placed in the first conveying mechanism 2. Here, the first conveying mechanism 2 usually adopts a conveyor belt structure. When working, the first conveying mechanism 2 conveys the packaging box 14 to its end, and the pushing plate 802 of the servo feeding mechanism 8 pushes the packaging box 14 from the conveyor belt of the first conveying mechanism 2 and pushes it along the guide groove 804 to the middle conveyor belt 501 of the second conveying mechanism 5. The synchronous paper suction mechanism 4 sucks the paper out of the paper material bin 3 and places it on the middle conveyor belt 501 of the second conveying mechanism 5 and sends it forward. When it reaches the bottom of the instruction manual suction mechanism 7, the instruction manual sucked from the instruction manual bin 6 by the instruction manual suction mechanism 7 also arrives synchronously and is placed on the paper. Through the first pressure strips 503 arranged on both sides of the pushing block 502, here, the first pressure strips 503 are fixed relative to the main frame 1. When the paper is placed When the packaging box 14 is placed on the instruction manual, the second pressure strip 504 prevents the paper bodies on both sides of the paper from shifting the packaging box 14 in the initial stage of erecting, thereby ensuring the accurate position during packaging; when the packaging box 14 continues to move forward, the paper body on the rear side of the paper sheet after erecting is bent and attached to the upper surface of the packaging box 14 by the action of the first paper folding guide rod 505 and the first paper folding pressure plate 506, and then glue is sprayed on the set position. At this time, the paper body on the front side of the paper sheet moves forward in an upright state, and when it reaches the second paper folding guide rod 507, it is bent to the top of the rear side paper body and bonded under the action of glue, thereby completing the packaging action of the packaging box 14.
