Longitudinal double-blade device for cutting machine

Abstract

The invention discloses a longitudinal double-blade device for a cutting machine. Two blades are provided and are symmetrically arranged in an internal space formed by a right lateral plate and a left lateral plate; the bottom ends of the blades are vertically fixed on the outer surface of a floating shaft; the floating shaft sleeves a fixed shaft; the opposite sides of the positions, which are connected with the blades, on the floating shaft are connected to spring pressure blocks by two left and right independently arranged connecting parts; the spring pressure blocks are connected with hand wheels by regulating rods; one ends of the right lateral plate and the left lateral plate are arranged on the fixed plate. According to the longitudinal double-blade device for the cutting machine, which is disclosed by the invention, by separately and independently arranging regulating devices of two blades, the problem that two blades cannot simultaneously carry out complete cutting, which is caused by an error of two blades, can be regulated in real time; a floating bearing and a fixed bearing are arranged into structures of which the middles of two circular arcs are straight sections, so that the longitudinal double-blade device is convenient to regulate the up-and-down positions of the blades without influencing the front-and-back positions and the error caused by shaking of a tool is avoided.

Description

technical field [0001] The invention relates to a cutting knife structure, in particular to a longitudinal double-knife device of a cutting machine. Background technique [0002] Advertisement, as a means of publicizing goods, is also rapidly gaining wide-ranging applications with the development of the economy. One of the important publicity methods of advertisements is to produce flat prints and post them on suitable occasions for publicity. The post-production of flat prints involves product cutting. When printing multiple images at the same time, a post-production double-cutting knife is required. Due to the small interval, higher requirements are placed on the operation accuracy of the double-cutting knife. In order to ensure that the two blades can cut through the screen at the same time, it is necessary to improve the processing accuracy of the blades and overcome the bearing error. The processing operation requires high requirements and is time-consuming and laborio...
