Paper shredding machine and paper shredding method thereof

Abstract

The invention discloses a paper shredding machine and a paper shredding method. The paper shredding machine comprises a paper passing plate, a paper sucking device, an optical recognition device, a paper shredding cutter, a control device and a shredded paper box with shredded paper classified, wherein the paper sucking device, the optical recognition device, the paper shredding cutter and the control device are arranged on the paper passing plate, the paper sucking device can suck waste paper placed on the paper passing plate one by one and convey the waste paper to the paper shredding cutteralong the paper passing plate, the optical recognition device is arranged at the position, between the paper sucking device and the paper shredding cutter, of the paper passing plate, when the wastepaper passes, the optical recognition device recognizes character positions on the paper surfaces of the front surface and the back surface of the waste paper, the paper shredding cutter is arranged at the tail end of the paper passing plate and can cut the waste paper, the shredded paper box with the shredded paper stored in a classified mode is arranged below the paper shredding cutter and is used for storing the shredded paper with ink and the shredded paper without ink in a classified mode, and the control device recognize the character positions on the waste paper through the optical recognition device and controls the paper shredding cutter to work.

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
