The second page folding leading-in mechanism 2 comprises a second page folding pushing block 22 which is arranged on the lateral side of the horizontal conveying path and used for pushing the second page to be folded inwards, and the second page folding pushing block 22 is driven by a pushing block driver;

third hinge guiding mechanism 3 includes second carousel 31, second carousel 31 is located the top in horizontal transport route, and the vertical setting of second carousel 31 and axial are perpendicular with horizontal transport route direction, the edge of second carousel 31 is circular profile, be equipped with an opening on the second carousel 31.

The structure and the operation principle of the first rotating disc 11 and the second rotating disc 31 can refer to the rotating disc structure in the chinese utility model patent application with application publication No. CN 104108481A.

As shown in fig. 5, the first folding guiding mechanism 1 further includes two first limiting rods 12 arranged side by side in the left-right direction and extending along the horizontal conveying path, and the two first limiting rods 12 are correspondingly located at the inner sides of the second folding 102 and the fourth folding 104, so as to limit the second folding 102 and the fourth folding 104 from being turned inwards, and avoid interference of the first folding 101 folded on the first rotating disc 11.

Further, the first folding guiding mechanism 1 further includes a first folding limiting rod 13 extending from the rear side of the first folding guiding mechanism to the front side of the second folding guiding mechanism, for limiting the first folding from being turned upwards, so as to facilitate the second folding 102 to be turned over and folded on the first folding 101.

In one embodiment, the pushing block driver is a pushing block driving cylinder 23, the moving path of the second flap pushing block 22 is inclined to the horizontal plane, and the second flap 102 is pushed to be turned inside and folded on the first flap 101 during the second flap pushing block 22 moves obliquely downward. The bottom of the head end of the second folding push block 22 is provided with an arc surface which acts with the second folding 102. It is to be understood that the push block driving cylinder 23 may be replaced with an electric cylinder or the like.

Further, the second folding guiding mechanism 2 further includes a glue gun 24 for spraying glue on the second folding surface to enable the third folding to be folded and pressed on the second folding 102 and to be glued and fixed at the same time. It will be appreciated that the glue gun 24 may also spray glue onto the first sheet surface so that the second sheet is folded over and secured to the first sheet. Of course, other glue guns can be arranged, for example, a glue gun is arranged on the rear side of the third folding page guiding-in mechanism, so that glue can be sprayed on the surface of the third folding page, and the fourth folding page can be conveniently glued and fixed.

In order to prevent the second hinge 102 from turning outwards before the second hinge pushing block 22 pushes the second hinge to be turned inwards, the second hinge guiding mechanism 2 further includes a second hinge limiting rod 21 for limiting the second hinge to the inside, and the second hinge limiting rod 21 is disposed above the second hinge pushing block 22. One end of the second folding limiting rod 21 is connected with the first limiting rod 12, and the connected end is inclined outwards to guide the second folding 102 to enter the inner side of the second folding limiting rod 21.
