The granular crusher consists of a set of rotating blades, paper combs and drive motors. The paper enters between the interwoven blades and is divided into small pieces of paper to keep it secret. Different crushing methods are suitable for different occasions. However, if you use certain occasions with high safety requirements, you must use a foam-like crushing method. For now, a shredder composed of four blades is a relatively advanced method. The cutting principle of the shredder is that the blade or cutter is placed in a staggered position, and the paper is torn under the action of the power supply. If the tool or blade is provided with a tool tip, the effect of the shredded paper entering the shredder is segmented or granular. Because there are few shredder products on the market that are aimed at daily office documents in the form of paper balls. Therefore, innovative design research was conducted for this product.

The main innovation of the design is that by changing the structure design of the traditional paper shredder, it can make up for the defect that the paper shredder on the market cannot handle fragmented files such as paper balls. The specific innovative design is as follows:

(1) The paper inlet of the shredder is improved into a bowl shape, and the paper inlet of the shredder with fixed specifications on the market is changed, so that the paper-like documents can be easily put in for shredding processing.

(2) The three roll blades can crush the paper balls placed inside, so that the shredded paper can be automatically rolled into the bottom storage part for storage. The rubber anti-skid design on the bottom can make the granular shredder work very stably. Push-button design, press the switch directly after putting shredded paper, and perform shredder operation.

(3) Less space occupation, easy to use, beautiful appearance, USB power supply, suitable for various office environments, easily smashing scattered files of various shapes.
