A static elimination device for high-speed digital printing machine

Abstract

The invention provides an electrostatic elimination device used for a high-speed digital printer. The electrostatic elimination device comprises an electrostatic ion rod which is used for eliminating electrostatics among paper and a control circuit which is used for controlling the starting and stopping of the electrostatic ion rod; the electrostatic ion rod is arranged on a paper path overturning plate at the paper exit of the high-speed digital printer, and is vertically arranged above the paper; the control circuit is connected with the electricity supply power end of the electrostatic ion rod through a conduction wire; and the control circuit is separately connected with the power end of the high-speed digital printer and a paper feeding control signal end for controlling the starting and stopping of paper feeding. According to the electrostatic elimination device, the control circuit starts and stops working of the electrostatic ion rod according to the paper feeding and paper stopping conditions of the high-speed digital printer; an automatic starting and stopping effect that the electrostatic elimination is started when the paper feeding begins, and the electrostatic elimination is stopped when the paper feeding stops is realized; no manual operation is needed during the whole process, so that the electrostatic elimination device is more convenient and safe; the electrostatic elimination device has an automatic electrostatic elimination function; a paper jamming phenomenon is avoided; the working efficiency is improved; the electrostatic elimination device is safe and harm-free; the assembly is convenient; and the work of the original printer is not affected.

Description

technical field [0001] The invention mainly relates to the field of accessories of digital printing machines, in particular to a static elimination device for high-speed digital printing machines. Background technique [0002] There is a lot of static electricity between the papers printed by the high-speed digital printing machine of the prior art, the stacked papers stick together, the papers are arched and sometimes jammed. The usual way to eliminate static electricity is to place the printed paper statically for 3-4 hours in a standard temperature and humidity environment and wait for the static charge to disappear naturally, or to add a simple static cleaning brush to the high-speed digital printing machine to control static electricity, but the method of eliminating static electricity The effect is very poor, and the high-speed printing is completed but cannot quickly enter the subsequent binding process due to static electricity. The paper jams due to static electrici...

The usual way to eliminate static electricity is to place the printed paper statically for 3-4 hours in a standard temperature and humidity environment and wait for the static charge to disappear naturally, or to add a simple static cleaning brush to the high-speed digital printing machine to control static electricity, but the method of eliminating static electricity The effect is very poor, and the high-speed printing is completed but cannot quickly enter the subsequent binding process due to static electricity. The paper jams due to static electricity will affect the work efficiency, and even cause the digital printing machine to stop in severe cases.
