Anti-deformation jointing die for board book

Abstract

The invention discloses an anti-deformation jointing die for a board book. The die comprises a carrier, a layer of rubber covers a gluing working surface of the carrier, bulges with closed outer contours are uniformly distributed on the rubber, and the distribution density of the bulges is set by taking the gluing area required for laminated board book inner pages as a standard. According to the die, the elasticity and flexibility of the working surface of the carrier are increased through the rubber, glue marks after gluing form relatively independent closed bodies one by one through the bulges, with closed outer contours, arranged on the rubber, stress is relatively closed, concentrated and uniform, and the phenomenon of mutual stress concentration among the glue marks when glue is driedand contracted is avoided; and the manufactured laminated board book is stable in quality and high in flatness, is not limited by the size of the board book, and cannot deform and wrinkle after beingused for a long time.

Description

technical field [0001] The invention relates to a printing device, in particular to a card-book anti-deformation joint mold which avoids deformation after the card-book pair is mounted by controlling the shape of gluing, and belongs to the field of printing equipment. Background technique [0002] Card books are mainly used to make commemorative albums, picture albums, stamp albums, collection books, etc. Due to the limitations of performance and structure, the inner pages need to have thicker size, higher strength and hardness, and at the same time, they need to have good support ,Not easily deformed. [0003] When making existing card books, the inner pages are evenly rolled by rubber rollers with smooth surfaces, and then mounted by a mounting machine, and finally the mounted inner pages are bound into a book to complete the production of card books. Although this kind of rubber roller with a smooth surface is fast and efficient in gluing, the amount of gluing is not e...

AI Technical Summary

Problems solved by technology

Although this kind of rubber roller with a smooth surface is fast and efficient in gluing, the amount of gluing is not easy to control, and it is easy to cause glue leakage and running. Wet the mounted pages, and the shrinkage force produced when the glue solidifies will cause wrinkles and unevenness on the mounted pages, which seriously affects the aesthetics and durability of the card book, resulting in a low yield of the card book. The quality of the book is greatly affected and limited

[0004] In order to avoid the above problems, in recent years, in the printing industry, local gluing has been used instead of the overall roll to reduce the amount of gluing when the inner pages of the card book are mounted, and to avoid the occurrence of stress concentration in the later stage. However, how to carry out local Gluing, how to control the gluing process and method, has not been effectively resolved
