Book gluing and binding method

Abstract

The invention discloses a book gluing and binding method. The method comprises the steps of book feeding treatment, book back treatment, gluing, covering and book shaping. A page detection device is arranged, so that unqualified pages are prevented from flowing into subsequent procedures, the qualification rate of books is effectively improved, and the waste of raw materials is avoided; a book back treatment mechanism is redesigned, so that paper scraps are prevented from affecting adhesion of glue, strength of the books is improved, meanwhile, the paper scraps on the pages can be prevented from falling into a glue pool, and purity of the glue is guaranteed. A first glue roller, a second glue roller and a distance sensor are arranged, so that gluing of the pages is neither too thick nor too thin, gluing is more uniform, waste of the raw materials can be avoided, and strength and reading experience of the books are not influenced. PUR hot melt adhesive is adopted for book adhesive binding, so that the reading comfort of a reader is improved, and use at high temperature or low temperature can be facilitated. Finally, the cooling time of PUR adhesive coating is shorter, so that the book processing speed is increased.

Description

technical field [0001] The invention belongs to the technical field of book binding, and in particular relates to a book binding method with gluing. Background technique [0002] Perfect binding is a printing process that does not use iron wire or thread, but glues the book block with glue, from book publishing to automatic binding. [0003] At present, some book manufacturers have the following problems when gluing and binding books: some pages will not be aligned or missing pages will be folded after the pages are aligned, and there is a lack of equipment for page detection, resulting in unqualified The pages of the book flow into the follow-up processing program, and the books processed by these unqualified pages are all unqualified products; when the pages are processed on the back of the book, it is necessary to increase the roughness of the glued surface of the pages through roughening and grooving, which will lead to There is a certain amount of dandruff on the back ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for binding books with gluing, so as to solve the problem in the above-mentioned background art that some pages are not aligned or pages are missing or folded after the pages of the book are aligned. At the same time, there is a lack of equipment for page detection. , causing unqualified pages to flow into subsequent processing procedures, and the books processed by these unqualified pages are all unqualified products; when the pages are processed on the back of the book, it is necessary to increase the roughness of the glued surface of the pages by roughing and grooving , which will lead to a certain amount of dandruff on the back of the book. The existence of these dross will lead to a poor bonding effect between the glue and the pages, which will affect the strength of the book; It is inconvenient to flip, and the thinner glue will lead to a lower service life of the book; the use of glue is not advanced enough, and EVA hot melt glue is still used to bind books. The performance of EVA hot melt glue is poor, and the cooling and solidification time is longer, which affects the book. The problem of processing efficiency
