[0031] Pressure maintaining assembly 3, said pressure maintaining assembly 3 is mounted on the first support plate 12 and arranged close to one side of the lower folding end face assembly 14.

[0032] Continue to refer to Figures 1 to 5 As shown, in this embodiment, it further includes a product transmission line, and the lower folding end face mechanism 1 is arranged close to one side of the product transmission line; the product on the product transmission line, that is, the packaging box of the notebook computer, has its end to be sealed facing the lower folding end face mechanism 1. After the packaging box is transmitted in place, the lower end face of the sealed end of the packaging box is arranged on the lower folding end face assembly 14, and the lugs 102 at both ends of its lower end face are respectively arranged above a folding lug assembly 13, while the upper folding end face assembly 24 and the tongue piece assembly 25 are located above the upper end face of the sealed end of the packaging box. At the same time, both the first X-axis translation mechanism 21 and the first Z-axis lifting mechanism 22 directly adopt linear motor modules, and there is no limitation to this. With their mutual cooperation, the upper folding end face assembly 24 and the tongue piece assembly 25 can be driven to perform translation and lifting movements so as to fold the upper end face and the tongue piece 101 of the packaging box.

[0033] During operation, first, the two lugs 102 at the lower end face of the packaging box are folded upward by the two folding lug assemblies 13. Subsequently, the lower folding end face assembly 14 folds upward the lower end face of the packaging box so that the lugs 102 are inserted into the seal of the packaging box. Subsequently, the tongue piece 101 at the upper end face of the packaging box is pressed and bent downward by the tongue piece assembly 25. After the tongue piece 101 is bent in place, the upper end face of the packaging box is then pressed and bent downward by the upper folding end face assembly 24 so that the tongue piece 101 is inserted into the corresponding bayonet in the seal of the packaging box.
