Paper conveying device

Abstract

The invention discloses a paper conveying device, comprising a continuous working unit and an intermittent work unit; an eccentric control device is arranged between the continuous work unit and the intermittent work unit; when the intermittent work unit works, the eccentric control device gradually lengthens a first paper path between the continuous work unit and the intermittent work unit; the eccentric control device for changing the length of the first paper path is arranged between the continuous work unit and the intermittent work unit, and is used for gradually lengthening the first paper path, so the speed of a third paper path entering the intermittent work unit is slowed, and the intermittent work unit has enough time to perform operations such as die cutting or gold stamping on the third paper path entering the intermittent work unit. While being operated at a high speed, the paper conveying device can perform intermittent operations such as die cutting and gold stamping on the paper path, the paper conveying device meets the printing demands of a long order form, the obtained printed paper product has high quality and the work efficiency is high.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a paper feeding device. Background technique [0002] With the progress of society, printing machines often need to cooperate with intermittent working units such as flat die-cutting, flat pressing and hot stamping, so as to improve product quality, work efficiency and production cost. However, for continuous paper printing machines, if you need to use intermittent working units such as flat die-cutting and flat pressing hot stamping, you need to change the continuous operation paper path to intermittent operation paper path. , can be used in conjunction with flat-press flat-die-cutting, flat-press hot stamping and other intermittent working units to process continuous paper. [0003] At present, there are two ways to change the continuous paper path from the continuous motion state to the intermittent motion state: [0004] 1. In the paper feeding device of the print...

AI Technical Summary

Problems solved by technology

The intermittent working group can be added to the continuous paper printing machine, but because the swing speed of the paper roller swing arm is limited, the operating speed of the printing machine is also limited, and there must be continuous paper at both ends of the intermittent operation paper path , so that the intermittent operation paper path in this mode cannot perform paper-cut die-cutting operations
