Embodiment Construction

[0031] The present invention will be further described in detail through specific embodiments below.

[0032] The reference signs in the accompanying drawings of the specification include: barrel 1, driving impeller 2, cutter 3, switch cover 4, mounting seat 5, discharge port 11, push block 12, spring seat 13, filter screen 14, guide groove 15 , Extension spring 16, driving wheel sheet 21, impeller shaft 22, copper sheet 41, I-shaped post 51, retaining sheet 52, and sheet 53.

[0033] Shredding methods of paper waste paper, including the following, such as figure 1 Shown:

[0034] S1, before adding waste paper into the barrel, let the driving motor drive the impeller to rotate, and then send the recovered waste paper into the barrel through the conveyor belt. After the waste paper enters the barrel, the driving wheel on the driving impeller drives The waste paper rotates, and when the waste paper rotates, it moves relative to the cutter on the inner wall of the barrel, and t...

Abstract

The invention relates to the technical field of paper making, in particular to a paper shredding method of waste paper used for paper making. The method comprises the steps that firstly, the waste paper is fed into a material barrel through a conveying belt, the waste paper is rotated in the material barrel through a driving impeller on the bottom of the material barrel, the waste paper is rotated so as to move relative to cutting knives, and the cutting knives cut the waste paper up; secondly, sheet copper is made to be aligned to a gap of a power-on circuit wire of an electromagnet due to the rotation of an impeller shaft, the electromagnet is powered on, when the sheet copper is not aligned to the gap of the power-on circuit wire of the electromagnet, the electromagnet is powered off, and so repeatedly, the electromagnet is powered on intermittently; thirdly, when the electromagnet is powered on intermittently, the electromagnet attracts a push block down repeatedly, and the push block repeatedly moves downwards, so that the shredded paper on a filter screen is scraped off; fourthly, the shredded waste paper is thrown away from a material discharging outlet in the rotating process of driving impeller blades. In the method, the push block reciprocates up and down, so that the material discharging outlet is prevented from being blocked, and meanwhile, the situation that the waste paper is unevenly cut up is prevented.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for shredding waste paper for papermaking. Background technique [0002] Trees are the main raw materials for the papermaking industry. Due to the long growth cycle of tree resources and the limited existing tree resources, the problem of limited raw resources is solved by waste paper treatment. Waste paper treatment is the process of reprocessing recycled waste paper to obtain qualified fibers for making paper products. The recycling and reuse of waste paper is conducive to protecting the environment, protecting forests and saving resources. [0003] The existing waste paper shredder includes a material barrel and a conveyor belt. The discharge port of the conveyor belt is located directly above the material barrel. A driving impeller is installed at the bottom of the material barrel. The waste paper inside rotates at a high speed driven by the driving impeller, a...
