Description

Waste paper shredder{Waste paper shredder}

The present invention relates to a waste paper shredding device, and more particularly, to a waste paper shredding device capable of significantly increasing the grinding performance of the device by a simple configuration and operation structure.

In general, a system that treats waste paper generated during the manufacturing process of a paper factory or waste boxes used for packaging products in a distribution center reduces the volume of waste paper to facilitate storage or transportation, while reducing the amount of dust generated during the disposal process. By reducing the amount of waste, environmental pollution and waste of resources can be reduced.

Such a treatment system usually consists of a shredding device that crushes bulky waste paper to a certain size or less, a separator that separates and treats dust and foreign matter contained in the waste paper by sucking out the shredded waste paper from the shredding device, and a waste paper connected to the separator. It may be configured to include a compression device for pressurizing and a dust collector for filtering dust.

In this configuration, depending on the shredding size of the waste paper by the shredding device, problems such as a decrease in mobility or clogging of the waste paper transferred to the separator may occur, or a decrease in compressive force in the compression device may occur, so that the shredding capability of the shredding device The overall performance of the system may be influenced by this.

However, the conventional crushing device has a limitation in easily exiting the waste paper due to the double drum structure, and there is a problem that some waste paper may accumulate inside the drum, so that the crushing efficiency decreases or the operation of the device is not smooth. In addition, the conventional crushing device has a limitation in elaborate crushing during a short period of time passing through the waste paper by uniformly forming the configuration of the crushing drum itself or the shape or arrangement of crushing blades provided therein.
