Description

Technical Field

[0001] The invention relates to the technical field of book production, folding and binding, and in particular to a printing, folding and binding integrated device based on book production. Background Art

[0002] A book refers to a bound work, including paper books, silk, bamboo slips, parchment scrolls, etc. Human social life requires the transmission of information and the exchange of ideas. Before the emergence of writing, people mainly communicated with each other through language, but language was limited by time and space. Therefore, the ancients used methods such as knotting ropes, carving wood, and simple graphic symbols to help memory. Books refer to works that are compiled or created for the purpose of spreading knowledge, introducing experiences, expounding ideas, and promoting ideas. They are written, engraved, and printed on certain materials. In the process of book production, multiple processes are required to complete the manufacturing and binding to form a book for use.

[0003] With the development of science and technology, the ways of book binding have also become different. Currently, the wireless adhesive binding book technology has become the mainstream in the book market. However, before gluing, the folds of the printed books must be completely milled open. If the printing and binding links are not handled or operated properly, it is easy for pages to scatter or fall off, and the pages are not firmly bonded.
