High-quality online monitoring book and periodical production process capable of improving cementing quality

Abstract

The invention discloses a high-quality online monitoring book and periodical production process capable of improving cementing quality. The high-quality online monitoring book and periodical production process is characterized by comprising the following steps: step 1, plate making; step 2, pre-printing; step 3, detecting the quality of a printed product during printing; the quality of printed matters in the whole printing process is ensured; 4, manufacturing a bulk book block; 5, making a cover; 6, the book block and the cover are bonded; according to the method, the back ridges of the sections are coated with the graphene heat-conducting hot melt adhesive coating through the online gluing device, after the covers are bonded, the graphene heat-conducting hot melt adhesive between the sections is molten and bonded again under the action of high temperature, graphene has an ultra-strong heat-conducting effect, reinforced connection between the sections is achieved, the digital detection standard is achieved, and the detection efficiency is improved. Compared with naked eye judgment of workers, the method is more accurate and reliable, the printing quality problem in the printing process can be rapidly and accurately recognized, and the books and periodicals after adhesive binding are not prone to breakage and long in service life.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a high-quality online monitoring book production process capable of improving the quality of glue binding. Background technique [0002] In recent years, the level of pre-press and printing automation of printing companies has been continuously improved, and a lot of labor has been liberated. However, they still rely heavily on labor in the quality inspection process; especially in the printing process of books and periodicals, including pre-press and post-press processes, pre-press Including pattern and content design, proofreading and printing, post-press including folding, binding, etc. Pre-press includes pattern and content design, proofreading and printing. Most of them still rely on manual labor to control the printing quality with their own experience; and for post-press, the traditional printing industry currently uses hot-melt adhesives to glue paper. Melt adhesive is ...

Pre-press includes pattern and content design, proofreading and printing. Most of them still rely on manual labor to control the printing quality with their own experience; and for post-press, the traditional printing industry currently uses hot-melt adhesives to glue paper. Melt adhesive is a solid soluble polymer that does not require solvents and does not contain moisture; hot melt adhesives are solid at room temperature, and when the hot melt adhesive is heated and melted to a certain temperature, it will flow and become a liquid with good viscosity. Different from hot-melt adhesives for other purposes, hot-melt adhesives used in books and periodicals not only require hot-melt adhesives to have good bonding strength, but also require them to have good fatigue resistance and bending properties. This is because ordinary hot-melt adhesives The anti-fatigue bending performance of the adhesive is poor. When reading books and periodicals many times, the hot melt adhesive is easy to break, causing the pages to fall off; For example, a Chinese patent for a perfect binding process for book printing; the perfect binding process disclosed in the application number 201811239125.4, through the copolymerization of EVA with a VA content of 40-42% and ethylene-1-octene with good flexibility and high bonding strength After mixing the compound and ethylene-ethyl acrylate copolymer, the mixture A obtained by melt-blending with malein rosin, zinc oxide powder and pentaerythritol, and then mixed with EVA, waxes, bentonite, anti After the oxygen agent and anti-blocking agent are mixed, the hot melt adhesive obtained has good bonding strength and fatigue resistance bending performance; in this way, the service life of books and periodicals is improved; different binding methods are also used, such as many books and periodicals now use locking glue Back-stitching, also known as thread-locking adhesive binding, when binding, each signature is firstly threaded and then glued, and the back is not milled when gluing. This binding method produces a strong and flat book, but this method of binding , between each signature is still only relying on the adhesion of the hot melt adhesive on the back of the book block, after reading for a long time, there will still be cracks
