AI Technical Summary

Technical Problem

During the high-speed printing process, existing offset printing machines have problems such as deformation, expansion, loss, scrap sheets, and incomplete paper collection, resulting in low quality of printed products, slow operation speed and insufficient stability.

Method used

A high-speed anti-scratch monochrome double-sided offset printing machine consisting of a paper feeder, a flat paper mechanism, a regular paper delivery component, a reverse and front frame, a roller, an ink-washing road system, a paper collection roller and a guide rail is designed. It adopts a tapered roller bearing structure, an electrostatic elimination device, a non-stop paper-mounted mechanism, an axial adjustable anti-scratch paper tray and a fully enclosed guide rail structure.

Benefits of technology

The printing speed is achieved to reach 15,000 sheets/hour, the quality of the printed product is improved, the waste sheets and paper collection is reduced, and the stability and operation convenience of the machine are enhanced.

Abstract

The invention relates to a high-speed anti-smudge monochrome double-sided offset printing machine, which comprises a paper feeder, a flat paper mechanism, a regular paper delivery component, a back side frame, a front transfer roller I, a front transfer roller II, a back side impression roller, a back side rubber roller, a back side printing plate roller, a back side ink path system, an intermediate transfer roller I, an intermediate transfer roller II, a front side frame, a front side ink path system, a front side printing plate roller, a front side rubber roller, a front side impression roller, a paper collection roller, a paper collection guide rail, a paper collection frame, a paper collection fan and a paper collection table. The paper feeder with an anti-static device, a regular paper delivery component adapted to high-speed paper transfer, a roller with a tapered roller bearing and a 3X4 stepless adjustable speed paper pressing fan are adopted, an anti-smudge paper tray with a reduced contact area is provided, and a flat paper mechanism and a non-stop paper feeding mechanism are added, thereby ensuring that the machine can run at a speed of 15,000 revolutions per hour.
