Problems solved by technology

[0003] The shredding process plays an important role in the mass production and processing of copy paper. Generally, shredding is a process step in which waste paper is sent to a shredder for shredding and preliminary filtering; The disintegration is not uniform enough, resulting in the remaining large paper in the shredded paper, which will affect the quality of further pulping

Abstract

The invention relates to a preparation method of copy paper. The preparation method comprises the following steps: (1) disintegrating: feeding waste paper into a paper shredder, and carrying out repulping and filtering; (2) pulp preparing; (3) papermaking; (4) dehydrating and drying; (5) rewinding and cutting selection; (6) paper feeding; (7) surface treatment; and (8) packaging, wherein the papershredder in the step (1) comprises a machine body, a feeding barrel arranged at the top of the machine body, a stirring mechanism arranged in the machine body and a shaking filtering screen mechanism, the stirring mechanism is connected with the center of the top of the machine body, and the shaking filtering screen mechanism is arranged below the stirring mechanism. According to the preparationmethod of the copy paper, through the cooperation of the stirring mechanism and the shaking filtering screen mechanism, the paper is fully disintegrated, the disintegration uniformity of the paper isimproved, and the preparation method is simple in structure and easy to implement.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for preparing copy paper. Background technique [0002] China is a big paper-making country, and the consumption of wood pulp alone reaches more than 20 million tons every year. The frequency of use of copy paper in daily work is very high, and the production efficiency and production quality of copy paper directly affect our daily life. [0003] The shredding process plays an important role in the mass production and processing of copy paper. Generally, shredding is a process step in which waste paper is sent to a shredder for shredding and preliminary filtering; The disintegration is not uniform enough, resulting in the remaining large paper in the shredded paper that has not been disintegrated, thereby affecting the quality of further pulping. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings and deficienci...
