Description

Shredded wastepaper processing apparatus of a paper shredder with compression enlarging apparatus}

The present invention relates to an apparatus for processing shredded gripping in a paper shredder, and more particularly, to pulverized shredded phage which is easily deformed or crushed in pieces of shredded paper under low noise, and present in the dehydrating cylinder. The present invention relates to a shredded gripping apparatus of a document shredder having a compressive force increasing device for increasing the dehydration rate.

In general, in the process of processing shredded paper in the paper shredder which is used to dispose of printed paper documents including confidential documents in the office, the shredded paper shredder of the document shredder of Utility Model Registration No. 061378 (2002.3.28) The device uses a grinder and a screw to mix the shredded phage with water, create a mass of paper after dehydration, and generates a lot of noise due to the cutter blade of the grinder rotating at a high speed, thus preventing work in the office. In addition, due to the use of screw blades having one inner diameter and one outer diameter, there is a problem in that the dehydration rate is lowered due to a decrease in the compressive force of the pulp fractured phage inside the dehydrating part cylinder.

The present invention has been devised to solve the above problems, and when crushing the shredded pieces of paper mixed with water, it is possible to improve the low noise and the crushing force and to increase the dehydration rate for the pulped shredded phage. The purpose is to provide a structure that can increase the pressing force so that.

The ultimate goal of increasing the compaction force in the compaction force increasing device, which is the core of the present invention, is achieved by minimizing the ratio of water in the pulping fragments mixed with water, that is, achieving a high dehydration rate.
