Book trimming device of double-face book trimming machine

Abstract

A book trimming device of a double-face book trimming machine comprises a rack, cutter holders and blades which are arranged on a cutter shaft, a book cutting table, a cutter holder regulation mechanism and a power transmission device; a left cutter holder and a right cutter holder are arranged on the cutter shaft and are respectively provided with a cutter shell and a blade; adjusting screws for adjusting the left and left blades to be synchronous are arranged on the left and right cutter shells; the cutter edges of the left and right blades are positioned in the same plane due to the adjusting bolts; a book trimming oblique guide rail and a secondary guide rail are connected onto a rack wall board in a mode of crossing at a certain angle; a book trimming oblique guide rail slideway is internally provided with a main slider; a secondary guide rail slideway is internally provided with a secondary slider; an eccentric shaft is connected with the secondary slider and an auxiliary connection rod. The book trimming oblique guide rail and the main slider as well as the secondary guide rail and the secondary slider drive the cutter shaft by the connection rod to enable the cutter edges to downward cut in a front low and rear high mode. The book trimming device of the double-face book trimming machine is simple in structure, low in cost, timesaving, laborsaving, and convenient to operate and adjust, and two sides of a book are cut at one step.

Description

technical field [0001] The invention relates to a double-side trimmer, in particular to a book-cutting device of the double-side trimmer. Background technique [0002] The book cover folding front opening machine (also known as the front opening machine) can only cut the front opening of the book and close the cover, but cannot cut the two sides of the book. Manually transfer to the three-side trimmer and then cut the two sides of the book. Like this, the equipment cost is high, the labor cost is high, and the production efficiency is low, which cannot meet the needs of modern production. In the previous book cutting device of the book cutting machine, the synchronization of the two cutting knives was not completely consistent, and the distance between the knife edge and the book was parallel to the cutting when the book was cut down. Contents of the invention [0003] In view of the deficiencies in the background technology, the technical problem to be solved by the pres...

Problems solved by technology

[0002] The book cover folding front opening machine (also known as the front opening machine) can only cut the front opening of the book and close the cover, but cannot cut the two sides of the book. It is manually transferred to the three-side trimmer and then cut the two sides of the book. In this way, the equipment cost is high, the labor cost is high, and the production efficiency is low, which cannot meet the needs of modern production.

In the previous book cutting device of the book cutting machine, the synchronization of the two cutting knives was not completely consistent, and the distance between the knife edge and the book was parallel to the down cutting when cutting the book. The book cutting force was large, the blade was easy to wear, and the effect was not ideal.
