As a further scheme of the invention, the hairbrushes are arranged in a plurality of groups, the hairbrushes are uniformly arranged on the right side of the air faucet, and the top ends of the hairbrushes are 6mm higher than the bottom surface of the page.
The brush rubs the back of the book of page to clear away the shredded paper bits on the back of the book, set up the air cock simultaneously and blow the back of the book, thoroughly clear away the shredded paper bits on the back of the book, avoid the shredded paper bits to influence the bonding of glue, also can avoid the shredded paper bits on the page to fall into simultaneously and glue the pond, influence the pure degree of glue.
As a further scheme of the invention, the first rubber roller and the second rubber roller are rotatably connected with the rubber pool, and the roughness degree of the outer surface of the second rubber roller is higher than that of the first rubber roller.
The back of the book of page carries out rubberizing for the first time by first rubber roll, and is more when first rubber roll rubber coating, then scrapes the glue on the page by first scraper, and is less when first rubber roll rubber coating, then the glue coating is thinner on the page, and the page directly has the space with first scraper, and distance sensor on the first scraper can't sense the object, then carries out the secondary by the second rubber roll and mends gluey, and the surface of second rubber roll is coarser, more does benefit to the glue and bonds, avoids the secondary to mend gluey still to rubberize not enough.
As a further scheme of the invention, the second rubber roller is driven by the lifting table to move up and down in the rubber pool.
The second rubber roll is used for supplementing glue to the pages, when the first rubber roll normally works, the position of the second rubber roll is lower, glue supplementing operation is not carried out, and when the glue on the first rubber roll is insufficient, the second rubber roll is lifted to supplement the glue.
As a further scheme of the invention, the glue coating products used in the glue coating machine are PUR hot melt glue.
Compared with the standard EVA hot melt adhesive, the PUR glue coating has the advantages that the coating amount of the spine gum is less, the glue consumption is less, the strength is not reduced, but the strength is improved, the PUR glue coating is softer than the standard EVA hot melt adhesive, therefore, books and periodicals are unfolded very smoothly, the books and periodicals can be well spread without being pressed by hands during reading, the reading comfort of readers is improved due to the smoothness of books, meanwhile, the PUR glue coating also has the characteristic of good environment adaptability, the PUR glue coating can be better used at high temperature or low temperature, the cooling time of the last PUR glue coating is half of that of the standard EVA hot melt adhesive, and the book processing speed is improved.
Compared with the prior art, the invention has the following beneficial effects:
1. the book page detection device is arranged, the book page detection device can detect the length and the width of the book page, whether the detected book page is qualified or not is judged by comparing the detected length and the detected width with the numerical value of a qualified product, if the length is unqualified, the book page is not aligned, if the width is unqualified, the problem that the book page is missing, folded or multiple pages is caused is solved, if the length is unqualified, the book page is not aligned, and different treatments are respectively carried out, so that the problem that unqualified book pages flow into subsequent processes is avoided, the qualification rate of books is effectively improved, and the waste of raw materials is also avoided;
2. the book back processing mechanism is redesigned, and the air nozzle, the brush, the grooving roller and the milling disc are designed to thoroughly remove broken paper scraps on the book back, so that the broken paper scraps are prevented from influencing the bonding of glue, the strength of books is improved, meanwhile, the broken paper scraps on pages can be prevented from falling into a glue pool, and the purity of the glue is ensured;
3. the first rubber roller, the second rubber roller and the distance sensor are arranged on the gluing mechanism, the first rubber roller is used for gluing for the first time, the distance sensor is used for detecting the gluing condition, and then the second rubber roller is used for supplementing glue, so that the gluing of the pages is not too thick or too thin, the gluing is more uniform, raw material waste can be avoided, and the strength and the reading experience of books can not be influenced;
4. glue and order to books and adopt the PUR hot melt adhesive, the PUR rubber coating is compared with standard EVA hot melt adhesive, the volume of scribbling of spine gum is less, although the volume of gluing is few, intensity has not reduced and has improved on the contrary, the PUR rubber coating is softer than standard EVA hot melt adhesive and is many, therefore books and periodicals are opened very smoothly, need not to press with the hand during reading and can be well opened flatly, the books planarization has improved reader's reading comfort, the PUR rubber coating still has the characteristics that environmental suitability is good simultaneously, can be better use under high temperature or low temperature, the cooling time of last PUR rubber coating is half of standard EVA hot melt adhesive, thereby book process velocity has been improved.
