The production line comprises a bookblock manufacturing assembly, a book cover manufacturing assembly and an adhesive binding machine, the bookblock manufacturing assembly comprises a bookblock printer, a folding machine and a collating machine, the collating machine is connected with the adhesive binding machine, the book cover manufacturing assembly comprises a book cover printer and a paper cutting machine, and further comprises a mark folding device connected with the paper cutting machine, the mark folding device comprises a rack and a supporting sheet, and the rack is provided with a middle seam folding assembly and an adhesive-binding face folding assembly; the middle seam folding assembly comprises a connecting plate and a pressing plate, and the connecting plate is provided with a measuring assembly; and the adhesive-binding face folding assembly comprises two indentation plates, an abutting plate is arranged at the end, away from the indentation plates, of the supporting sheet, two positioning plates are arranged on the two sides of the abutting plate, a crossbeam is fixed to the upper end of the rack and provided with a sliding groove, and the abutting plate and the pressing plate are slidably connected to the slidinggroove. Binding of bookblocks and covers is facilitated, generation of defective books is effectively reduced, and the phenomenon of waste of raw materials is reduced.

Description

technical field [0001] The invention relates to the technical field of book printing, in particular to a book printing production process and production line. Background technique [0002] Book printing is the process of materializing book design into books with physical form by using paper, various binding materials and printing technology. Book printing mainly adopts lithographic printing. The graphic part of the lithographic printing plate and the blank part are almost on the same plane. When printing, the water supply device supplies water to the blank part of the printing plate, and then the ink supply device supplies water to the printing plate. Ink, using the principle of immiscibility of water and ink, the ink can only be supplied to the graphic part of the printing plate, and then use the printing pressure to transfer the ink on the printing plate to the substrate through the blanket to complete the printing. The overall design of the book and its final shape, effe...

Problems solved by technology

[0004] The above-mentioned prior art scheme has the following defects: after the book block and the cover are made, glue is applied to the middle seam of the cover, and then bonded to the book block. The above-mentioned prior art is to directly bond the flat cover to the book block. When gluing the cover, the cover is in a flat state, so it is difficult to determine the position of the middle seam of the cover, there may be a phenomenon of gluing offset or excessive gluing area, and the cover in the flat state is bonded to the book block Sometimes, it is difficult to accurately find the best bonding position between the cover and the book block, so that the phenomenon of cover sticking will appear, which will increase the defective rate of book production, and the cover needs to be removed for reprocessing, resulting in the loss of cover materials and paper. waste, not conducive to sustainable development
