Description

Technical Field

[0001] The utility model relates to a paper cutter, in particular to a book cutting posture correction device. Background Art

[0002] The production of books includes the production process of cutting white paper, printing, binding into books, etc. After binding into books,

[0003] The excess parts of the edges of the other three sides of the book except the back are trimmed to make the books of the same size and the edges even.

[0004] Traditional book paper cutters require manual turning after cutting one side, adjusting the size, and then cutting the other side.

[0005] Manual steering and size adjustment are required to complete the cutting of the three edges of the book. In order to solve the safety problem of manually delivering books to the blade, the existing patent literature, such as "A Book Trimming Machine" with application number 201721331046.7, includes an operating table, a conveying device arranged on the operating table, a clamping device mounted above the conveying device for pre-clamping the book, a cutter assembly arranged on one side of the conveying device, and a driving device that drives the cutter assembly to cut the edge of the book. Before the cutter assembly cuts the book, the piston shaft of the pneumatic cylinder can abut against the side wall of the movable splint, and push the movable splint to overcome the elastic force of the spring and translate in the direction of the fixed splint to clamp the book firmly. When the cutting action is completed, the piston shaft retracts to disengage from the movable splint, and the movable splint can be reset under the elastic force of the spring. The book cutting machine with this structure requires the operator to adjust the cutting edge of the book many times, which is time-consuming, labor-intensive and inefficient, and cannot efficiently achieve efficient cutting of three-sided books.

[0006] As an improvement, someone has designed a three-sided book trimmer with a composite cutter, which can simultaneously trim the three edges of a book. However, this three-sided book trimmer has a complex structure, requires a large cutting power (more than 5 times higher than a single cutter), is difficult to process, and requires professional personnel to install and debug the cutter after the blade is blunted and sharpened, and has a high maintenance cost.
