Automatic paper feeding digital indentation paper folding machine

Abstract

The invention discloses an automatic paper feeding digital indentation paper folding machine, which comprises a paper feeding unit, an indentation unit, a paper folding unit, a paper collecting unit, a fan unit and an operating control unit, wherein the indentation unit mainly comprises a paper feeding rubber roll, an indentation tool, a paper discharging rubber roll, an indentation driving motor and a paper sensor; and the paper folding unit comprises a paper feeding rubber roll, a paper folding and conveying roll, a paper folding roll, a slotting tool and a slotting tool motor. By adopting the automatic paper feeding digital indentation paper folding machine, the problem of low efficiency caused by the need of manufacturing an indentation template for indenting, paper folding with the paper folding machine and the requirement of manual paper folding on a thick medium is solved; in the indentation paper folding machine, indentation and paper folding are completed simultaneously, and the entire process is set fully automatically without manual intervention; a lower air suction paper feeding mechanism for feeding paper without stopping is adopted, so that the working efficiency is increased greatly; and the indentation unit and the paper folding unit can work independently separately, so that the using flexibility is enhanced.

Description

technical field [0001] The invention relates to the technical field of creasing machines and folding machines in post-press equipment, in particular to a creasing and folding machine which is perpendicular to the paper feeding direction and directly performs insert-knife folding. Background technique [0002] In traditional printing, thicker paper exceeding 157g, if directly folded, often bursts the paper, exposing the pulp and destroying the picture; this is especially true in digital printing, where the toner is only pressed on the surface of the paper, no matter how thick the paper is, it can be folded directly The result is that the toner pops and the pulp is exposed. Therefore, it is necessary to indent and then fold the page, so as to ensure the integrity of the picture; [0003] Existing equipment and process: [0004] 1. The traditional equipment only has a single function, the creasing machine only has the creasing function, and the folding machine only has the fo...

AI Technical Summary

Problems solved by technology

[0004] 1. The traditional equipment only has a single function, the creasing machine only has the creasing function, and the folding machine only has the folding function. The key is that the traditional creasing needs to make the creasing template in advance for different jobs, and the efficiency is extremely low;

[0005] 2. Creasing and folding are two completely independent processes. When traditional equipment completes this work, it is necessary to transfer the creasing paper to the folding machine after creasing, and adjust the folding machine according to the result of creasing , to complete the folding process, labor-intensive, time-consuming, and low degree of automation

[0006] 3. Most of the traditional folding machines are fence-type structures, and the folding accuracy is poor, and usually only 200g / m 2 The following thin papers cannot be folded to meet the folding needs of thick media such as coated paper, heavy-weight coated paper, exquisite cardboard covers, and photo paper.
