Novel book back processing technology of perfect binding machine

Abstract

The invention relates to the technical field of book perfect binding products, in particular to a novel perfect binding machine book back processing technology which comprises the following steps: step 1, clamping, fixing and moving a whole book block; step 2, making the book back of the whole book block become neat from uneven; step 3; a plurality of transverse grooves are formed in the book back of the whole book block; 4, milling a plurality of transverse grooves in the book back of the whole book block to form thick and long fibers of the paper; and step 4, extruding and removing air in the pages by a'pressurizing device '. According to the method, thick and long fibers of paper are pulled out of the book back, so that the fibers can be better adhered to glue liquid in subsequent steps, and the adhesion firmness and the specification stability of a book cut subsequently are further improved; air between the inner pages can be extruded and removed, the inner pages of the whole book back are tightly attached and neat again, the problem that the book back is fluffy is thoroughly solved, and the defects that glue holes and bubbles are generated in the follow-up forming process of the book back, and the cover compaction size fluctuates, glue permeates and the like are overcome.

Description

technical field [0001] The invention relates to the technical field of book perfect binding products, in particular to a novel process for processing book backs of perfect binding machines. Background technique [0002] Books are an important carrier for the development of human society and culture. Only after the paper is printed, bound, and cut can it become a beautiful finished book. There are many forms of book binding, and perfect binding is one of the forms with the highest modern applicability and universality. Book binding generally needs to be folded into sheets and pages into a book, and then enter the machine of the perfect binding package, and then go through book block vibration, milling, slotting, book brushing, gluing, cover and creasing, supporting Solid clamping forming and other processes. [0003] The processes of back milling, slotting, and book brushing before the book block is glued are the processing technology of the glue-bound book back. The proc...

Problems solved by technology

[0006] 1. After a series of book back processing processes, the back part of the book that was originally clamped and tightly bonded by the book clip becomes bulky, and the paper scraps generated by the slotting knife will be caught by the gap between the book blocks, resulting in the brush may not be able to clean If the condition is clean, the glue on the back of the book will not be full and uneven, which will affect the quality of the back of the book.

[0007] 2. The back of the book is bulky, resulting in changes in the size and specification of the compacted boundary of the upper cover, such as Image 6 Dimension a in , resulting in unsightly shape of the finished book back and unstable quality

[0008] 3. The back of the book is bulky, and the residual air between the inner pages cannot be discharged when it is clamped and formed after gluing. It is easy to form glue holes and air bubbles in the glue layer of the back of the book, which directly leads to weak adhesion.

[0009] 4. The bulkiness of the back of the book directly affects the quality of subsequent gluing

When gluing, the glue is easy to seep into the gaps in the inner pages of the book block, so that the finished book will see uneven glue seepage in the process of reading and using. This is not allowed by the standard of perfect book binding. Thickening will directly affect the cutting accuracy of the downstream three-side trimmer
