Shredding device for waste paper making

Abstract

The invention relates to the field of paper-making equipment, in particular to a paper shredder for paper making with waste paper. The paper shredder comprises a material barrel, a bracket and a conveyor belt, the bottom of the material barrel is provided with a driving impeller, the driving impeller comprises an impeller shaft and driving impeller vanes fixed on the impeller shaft, the inner wallof the material barrel is provided with multiple rows of cutters, a discharging port is formed in the bottom of the material barrel, an intermittent powered-on electromagnet is arranged in the innerbottom of the material barrel, the impeller shaft is fixedly provided with a switch sleeve, and the switch sleeve is internally and fixedly provided with a copper piece for making the electromagnet powered on; the discharging port is provided with a filtering net, the inner wall of the material barrel is fixedly provided with a spring base, the spring base is connected with a tension spring, the tension spring is connected with a push block capable of scraping iron materials of the filtering net, the push block is located above the filtering net within the magnetic range of the electromagnet when the electromagnet is powered off, the push block is fixedly provided with a guide column, the inner wall of the material barrel is provided with guide grooves matched with the guide column, and the guide grooves are located in the two sides of the filtering net. According to the paper shredder, the discharging port is prevented from being blocked through the up-down reciprocating movement of the push block, and meanwhile, the waste paper is prevented from being shredded unevenly.

Description

technical field [0001] The invention relates to the field of papermaking equipment, in particular to a shredding device for papermaking from waste paper. Background technique [0002] Papermaking is made by combining pulped plant fiber water suspension on the net, dehydrating initially, and then compressing and drying. The raw materials for papermaking mainly include coniferous wood, broad-leaved tree wood and grass plants. The growth cycle is long, and the existing tree resources are limited, so the problem of limited original 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 abov...
