S6, folding the cover into a gluing surface matched with the book block and the book spine: two folds are formed at the center of the book cover formed in the S06 through the creasing plate 25 and the positioning plate 36, and the part of the book cover between the two folds is a gluing surface; when the cover is processed, the second control valve is closed, so that the cover falls on the supporting sheet 8, the cover can be hung at the upper end of the supporting sheet 8 under the action of the center seam, and the center seam can be abutted against the supporting sheet 8. The second cylinder 33 is opened, the abutting plate 32 abuts against the cover on the supporting sheet 8, and under the action of the third cylinder 27, the moving plate 26 drives the creasing plate 25 to move towards the cover to be creased, so that the creasing plate 25 is abutted with the positioning plate 36, and a crease is formed on the cover. At this moment, open the third control valve and make the front cover adsorb on butt plate 32, third cylinder 27 drives butt plate 32 and shifts up to slide along spout 10, the front cover that will accomplish the crease enters into the front cover rack of cementing machine 4, makes the relative distance between two locating plates 36 adjustable through rotating adjusting threaded rod 35, and adjusts the relative distance between two creasing plates 25 through sliding connection along 28, thereby reaches the effect of adjusting the relative distance between the two creases.

S7, gluing and sleeving a cover and a book block: bonding the spine to the bonding face formed in S6 on the binding machine 4 by applying a glue to the spine of the book block formed in S5;

s8, book cutting: and flattening and cutting three sides of the glued book by a cutting machine to obtain the finished book.

The implementation principle and the beneficial effects of the embodiment are as follows:

the center of the front cover is folded with the center seam through the center seam assembly, when the center seam is folded, 2/1 of the front cover to be folded is fixedly placed on the connecting plate 11, then the pressing plate 12 falls on the side line of the front cover and the connecting plate 11 to fold the center seam, the front cover with the folded center seam is placed on the supporting sheet 8, under the action of gravity and the structure of the front cover, the center seam of the front cover is supported at the upper end of the supporting sheet 8, at the moment, the abutting plate 32 moves towards the supporting sheet 8 and abuts against the center seam of the front cover on the supporting sheet 8, then the indentation plate 25 moves towards the supporting sheet 8, the positioning plates 36 are arranged on the two sides of the abutting plate 32 to enable the positioning plates 36 to be in butt joint with the indentation plate 25, two creases are folded on the front cover, a gluing surface matched with the spine of the book is formed between the two creases, the front cover and the book core are convenient to be adhered, and the phenomenon of the front cover being stuck, the book cover production method has the advantages that the book production quality is effectively improved, the waste of covers is reduced, the production input cost is effectively saved, and the production efficiency of book production is improved.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
