Description

Technical Field

[0001] The utility model relates to the technical field of printed matter packaging, in particular to a printed matter packaging edge glue tightening device. Background Art

[0002] After printing, books or periodicals generally need to be bound into volumes. The binding methods are mostly glue binding, stapling or thread binding. Glue binding is suitable for most books and periodicals, and has no restrictions on the thickness of the books, so it is widely used. The main equipment used in the glue binding process of books are pagination machines, glue binders, three-sided book trimmers, etc. The equipment is connected by conveyor belts, which can form a complete production line between the equipment, greatly reducing manual operations, and helping to improve production efficiency and production benefits.

[0003] When books are bound in a binding machine, usually after the spine of the book core is covered with glue, a book cover is put on the spine. The book cover and the spine are bonded together by cold gluing. After the bonding is completed, they are turned horizontally by a flipping mechanism and then spread flat on a conveyor belt and transported to the book cutting station. During the process of the book cover being cold-glued and transported on the conveyor belt, since the book cover is usually made of hard cardboard and folded, there is a certain degree of recovery at the fold of the book cover, which can easily cause the side of the book cover away from the conveyor belt to curl up, resulting in poor bonding quality between the book cover and the spine, affecting the quality of the book.

[0004] In order to solve the above problems, we have made improvements and proposed a printed product packaging edge glue tightening device. Utility Model Content

The book moves on the conveyor belt 1, and the motor 11 works to drive the active pulley 10 to rotate. With the cooperation of the driven pulley 8, the belt 9 moves on the outside of the pressing plate 7, and the book passes under the pressing plate 7. When the book passes under the pressing plate 7, the pressing plate 7 squeezes the book and the book cover, so that the book cover fits tightly against the book, effectively avoiding the phenomenon of the book cover warping after bonding.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
