[0018] The position sensing system 4 can adopt a visual sensing scheme or a distance sensing scheme in existing mature technology; the push plate 515 is perpendicular to the turnover rod 513, and the folding working principle and method are as follows: after the position sensing system 4 identifies that the unfolded paperboard with a fold reaches the folding and splicing assembly 5, the top plate 522 is driven to rise by the top lifting driving devices 521 on the front and back sides, the paperboard on the front and back sides is lifted, and the whole paperboard is slightly lifted to leave a contact space for the push plate 515, then the first turnover driving motor 511 drives the turnover rod 513 to turn upward, and at the same time the turnover rod 513 turns, the first telescopic driving device 514 can drive the push plate 515 to move, so that the first turnover assembly 51 is on the underside of the first conveying device 1, realizes the superposition of the circular motion and the linear motion, realizes the variable-diameter turnover of the push plate 515 around the shaft, and then the push plate 515 is smoothly moved to the upside of the first conveying device 1 and continues to contact and clamp and extrude the paperboard on the left and right sides at an upward angle, and at the end of the stroke, the horizontal movement is completely transitioned, and under the clamping of four sides, the folding of the upper opening box body is completed.

[0022] Specifically, as shown in Figures 4-6 , the filling assembly 3 comprises a transverse moving frame 31, a transverse moving platform 32 transversely and slidingly connected to the transverse moving frame 31 and a transverse moving driving device 33 for driving the transverse moving platform 32 to move, the transverse moving platform 32 is provided with a lifting device 34, the bottom end of the lifting device 34 is provided with a suction head 35, the suction head 35 can not only be used for sucking the goods 8, but also can be used for pressing the four paperboards at the upper opening when there is no air.

[0023] The transverse moving platform 32 is provided with a plurality of guide holes, the suction head 35 is connected with a guide rod 37, the guide rod 37 is vertically and slidingly connected to the guide holes, which can effectively improve the stability of the movement of the suction head 35; specifically, the lower end of the guide rod 37 and the output end of the lifting driving device are connected with an air supply platform 36, and the suction heads 35 are collectively connected to the air supply platform 36, which can effectively improve the stability of the suction head 35.

[0027] Specifically, the working principle of the lever device 38 and the push rod device 39 is as follows: the two contact wheels 384 are first brought close to each other and then moved away from each other through the first rotary drive device 381. When approaching, they first continue to push the cardboards at the front and rear ends of the box opening. Then, as they continue to approach, they will enter a state of being separated from the cardboard. Then, they will move away from each other to contact the inner side of the cardboard, causing the cardboard to turn outward and enlarge the opening. After the contact member adopts a hook shape, the push rod device 39 can also adopt a similar principle. When pushing the cardboards at the left and right ends of the upper opening of the box, the cardboards are turned inward.

After that, the lifting device 34 above drives the adsorption head 35 to move downward to press the cardboards on the left and right sides of the upper opening of the box body. After pre-pressing, the lever device 38 and the push rod device 39 are completely withdrawn, and then continue to press down to achieve sealing. A binding machine is integrated on the ventilation table 36 to fix the box body, and the packaging can be completely completed; a lifting drive platform 9 can also be added at the rear to drive the binding machine for binding and fixing.
