Paper cutter with cutting knife moving vertically

Abstract

A paper cutter with cutting knife moving vertically is composed of support frame consisting of vertical piles and top beams, air-cushion bench, paper pusher with more vacuum sucking disks, motor-leading screw drive mechanism, knife holder, and knife. Said knife is linked to a electric hydraulic cylinder mounted to top beam for moving up and down. Its advantages are high cutting precision and high safety.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and in particular relates to the structural improvement of a paper cutter. Background technique [0002] The main structure of the traditional paper cutter is as follows: figure 1 Shown (published by Chemical Industry Press entitled "post-press processing", Jin Yinhe, September, 2001), including frame 11, the workbench 12 installed on the frame, the push paper arranged on the workbench Device 13, paper presser 14, driving device and the knife bed driven by it, and the paper cutter 15 installed on the knife bed; wherein the driving device is driven by a worm and gear controlled by a hydraulic clutch, and drives the knife bed for tilting motion through a connecting rod, so that The blade cuts at an angle. The paper pusher can not only push the paper forward, but also be used as a guide for positioning; the paper presser compresses the positioned paper 10, so as to avoid errors caused b...

AI Technical Summary

Problems solved by technology

The most important thing is that the paper must be pressed, so the size after the knife must be limited, so the accuracy of the final knife of the finished product still depends entirely on the technical level of the operator, and it is difficult to meet the final unified specification requirements

In addition, the steel edge of the blade of this paper cutter 15 is generally about 70mm, and it is impossible to make the best use of it by using the adjustment of the connecting rod.
