Paper shredder and paper shredding method thereof

Abstract

A paper shredder and a paper shredding method thereof, the paper shredder includes a cardboard, a paper suction device arranged on the cardboard, an optical identification device, a shredding cutter, a control device and a shredding bucket for shredding classification , the paper suction device can suck the waste paper placed on the paper passing board one by one and convey it to the shredding cutter along the paper passing board; the optical recognition device is arranged between the paper suction device and the On the cardboard passing between the shredding cutters, when waste paper passes through, the optical recognition device recognizes the font position on the paper on both sides of the waste paper; the shredding cutter is set at the end of the passing cardboard, The waste paper can be cut; the shredded paper barrel for sorting and storing the shredded paper is set under the shredding cutter, and is used for sorting and storing shredded paper with ink and shredded paper without ink; the control device recognizes according to the optical recognition device The position of the characters on the waste paper and control the shredding cutter to cut; so as to realize the separation of the part with ink on the waste paper and the part without ink.

Description

technical field [0001] The invention relates to the field of office applications, in particular to a paper shredder and a paper shredding method thereof. Background technique [0002] Under the situation of responding to the green theme of eco-environmental protection worldwide, secondary fiber has become an important fiber source for the pulp and paper industry. Therefore, the recycling and reuse of waste paper has attracted more and more attention. At present, the process of waste paper recycling is generally: sorting→shredding→deinking→removing residue, screening→washing→concentrating→bleaching→sending to beating. Almost every process of treatment consumes water and discharges waste water, but the largest amount of waste water is discharged in the deinking process, and various pollutants are also produced during the production of deinking agents to endanger the ecological environment. In addition, in the paper shredding process, a large part of the ink-free part that can...

AI Technical Summary

Problems solved by technology

Almost every process of treatment consumes water and discharges waste water, but the largest amount of waste water is discharged in the deinking process, and various pollutants are also produced during the production of deinking agents to endanger the ecological environment

In addition, in the paper shredding process, a large part of the ink-free part that can be directly used is crushed together with the ink-containing part, and participates in the recycling of paper pulp secondary fibers, which inevitably increases the amount of deinking agent. The use of it leads to the discharge of a large amount of pollutants and aggravates environmental pollution
