Bidirectional bias cutting device of triple-side book cutting machine

Abstract

The invention discloses a bidirectional bias cutting device of a triple-side book cutting machine, which can use one cutter to cut three sides of books, wherein a cylinder fixed front base is respectively connected at the upper parts of a left and a right front vertical plates, a cylinder rotating base is arranged between the cylinder fixed front base and a gantry rack, and a paper cutting cylinder is inversely arranged at the cylinder rotating base; pin roll sleeve holes are respectively arranged at the positions close to the two ends of the upper parts of the left and the right front vertical plates, a first left cutting positioning cylinder, a first right cutting positioning cylinder, a second left cutting positioning cylinder and a second right cutting positioning cylinder are linked at the upper part of the back of the gantry rack in the way of corresponding to the four pin roll sleeve holes, the piston rod end parts of the four positioning cylinders are respectively sleeved with a swing pin roll, the four swing pin rolls are sleeved in the pin roll sleeve holes in a one-to-one correspondence way, left paper cutting swing arms are respectively sleeved on the two swing pin rolls at the left part, right paper cutting swing arms are respectively sleeved on the two swing pin rolls at the right part, and the lower parts of the left and the right paper cutting swing arms are connected with a cutter body; and the piston rod head of the paper cutting cylinder is connected with a drive pin roll, and the drive pin roll is pivoted with the middle part of a tool rest body. The device is applicable to cutting the stapled books.

Description

technical field [0001] The invention relates to a structural assembly of a small three-sided book cutter. Background technique [0002] The three-sided book cutter is usually composed of three cutting knives, door knife, left knife and right knife, and the corresponding parts. It can complete the three-sided cutting of books in one-time clamping with the cooperation of the book delivery trolley; its advantage is that it can be used in large quantities When cutting books of the same specification, the speed is fast and the efficiency is high; its disadvantage is that when cutting small batches of books with multiple specifications, it is necessary to frequently replace the clamping tool and adjust the positions of the book feeding trolley and the cutter, which affects the production of the whole machine efficiency and increased workload. [0003] When the book delivery trolley holding the book can be turned and positioned in addition to translation, a cutter can complete the...
