The function of the book cutter and its structural features

The cutter is a cutting device that is specifically designed to cut the front opening of the books, the sun-cuts, and the cutting of the foot.

Cutting books is the process of writing paperback books, except for setting up the mouth, cutting off the three edgings to become a book that can be read. Three-sided cuts also include severed book block cores and double-cuts. The purpose of three-sided cutting is:

(1) Make the draft of the books in line with the provisions of the national standard GB788 (on books, magazines, and format size);

(2) Make it easy to read and make books and books have a neat appearance;

(3) It is convenient for special books to be modeled and processed on three sides of the incision;

(4) When hardcover books are finished, book blocks can be evenly staggered to create conditions.

The classification of the book cutter: According to the input mode of the product to be cut, it is divided into an automatic three-side cutter and a semi-automatic three-side cutter.

The structure and composition of the book cutter

It is mainly composed of a foot control mechanism, a book delivery mechanism, a book pressing mechanism, a cutting mechanism, and a book publishing institution. The operating principle and structure of the three-sided cutters produced in China are basically the same. They have a high cutting performance and can cut books, magazines, and albums with hardcover, paperback, and saddle-stitching that are 8 to 100 inches wide.

Three sides of the cut books have multiple cuts and single cuts. Multiple stacking is generally used for stand-alone production, while single-cut production is used for linked production lines.

The process of cutting books on three sides: The stack of books to be cut is first fed into the underside of the tongue plate of the book holder 1 , and the stack of books is automatically pressed, and then the stack of books is sent to the cutting position. When the book stack is pressed by the book press 2 , the left and right side knives 3, 4 move downwards at the same time, and according to the adjusted size, the books are cut off and the foot is lifted. The front mouth of the cut book is moved downwards. After the front mouth is cut, the book is automatically raised and reset. The book that is cut is sent from the robot of the book delivery institution to the conveyor belt.
