The automatic flattener comprises a book clamping device, a slide-clamping air cylinder, a middle clamping device, page turning devices and page spreading devices, wherein the book clamping device comprises a front clamping unit and a rear clamping unit; each of the front clamping unit and the rear clamping unit comprises a main frame, a horizontal clamping screw, vertical clamping screws; an upper clamping plate, a lower clamping plate, clamping caps, lower moving plates, upper moving plates and springs; the middle clamping device comprises a moving plate, a pair of front rotary rods, a pair of rear rotary rods, a middle clamping plate, clamping plates and clamping springs; each page turning device comprises a page-turning air cylinder, a page-turning rotary rod and a page-turning sucker; and each page spreading device comprises a horizontal-spreading air cylinder, a vertical-spreading air cylinder and a page spreading block. The automatic flattener provided by the invention is applicable to automatic spreading of the edges and corners of various books (big books, small books, thin books, thick books and the like); the application scope is broad; the spreading effect is good; and the working efficiency is high.

Description

technical field [0001] The invention relates to the field of stationery, in particular to an automatic leveler for book curling. Background technique [0002] When the book has curled edges and corners, if you don't care about it, it will become more and more curled in the future when it is picked up and used, and it will look like sloppy ghosts. For the sake of neatness and beauty, and for the convenience of use, or just to have a good mood, we must trim these books. [0003] The existing common leveling methods are: [0004] (1) Cutting method [0005] Operation: Cut off the corners that are rolled up, and try to cut them into arcs when cutting too much. Trim or trim off the rolled sides. [0006] Effect: Not only the rolled up part is removed, but also the corner after trimming is not in the position of "edge" and "corner", so it is difficult to roll up again, which plays a preventive role. [0007] (2) Hand laying method [0008] Operation: Flatten the rolled corne...

But because the corners are still in the position of "side" and "corner", if it is not used properly and the folded writing is not stiff enough, it will still roll up again

[0013] The above three methods are three common methods of leveling the corners of the paper in the prior art, but the above methods are all manually operated, and there are also defects of damaging the books and changing the original appearance of the books. When the corners of books and valuable books are leveled, the above method is no longer suitable for the needs. In view of this, the present invention provides a device that can automatically level the corners of paper, which has the beneficial effects of:
