[0039] The suction conveyor belt 3 is located below the suction cup 12 . The suction conveyor belt 3 is arranged on the frame. The suction conveyor belt 3 is used to drive the paperboard pages to move along the page diagonal rod 22 .

[0040] The page opening mechanism is configured with a suction opening component, a page spreading component and a suction conveyor belt 3, so as to conveniently open the folded cardboard pages, reduce the operation intensity of workers and improve the page opening efficiency. In addition, the equipped suction conveyor belt 3 can also ensure the efficient opening of the book pages.

[0041] Specifically, in this embodiment, the moving direction of the cardboard page is forward. When the folded cardboard page is put in, the opening direction of the folded cardboard page is leftward. The extending direction of the page opening inclined rod 22 is from the left rear to the right front.

[0042] The folded cardboard page is put on the suction conveyor belt 3, and the suction conveyor belt 3 forms suction on the bottom surface of the cardboard page. At the same time, the suction linear driver 11 drives the suction cup 12 to move and suck up the top side of the folded cardboard page. The folded cardboard page is sucked out of an opening. At this time, the page opening linear driver 21 drives the page opening inclined rod 22 to extend into the opening, and the suction conveyor belt 3 drives the cardboard page to move forward. Under the action of the page opening inclined rod 22, the top side page of the cardboard page (that is, ) completes the operation of opening the cardboard page. Specifically,
