Description

Automatic compression paper shredder

Technical Field

The invention belongs to the technical field of paper shredder equipment, and particularly relates to an automatic compression paper shredder.

Background

Information becomes more and more important with the development of science and technology and times, and paper shredders play a role in keeping confidential regardless of whether personal information or company information is processed. In the information era, a lot of important information is stored on the internet in a data form, and also a lot of important information is transmitted by using paper as a carrier, so that the paper shredder mainly plays a role in destroying the important information, is commonly used in the office field for carrying out confidential treatment on paper documents, and is divided into a hand-operated paper shredder, a desktop paper shredder, a small personal/household paper shredder, a medium-sized office paper shredder, a large-sized office paper shredder and the like according to different use objects and use environments along with the development of the paper shredder. The paper shredder has two main parts, one paper cutter and one electric motor connected closely via belt and gear, and the motor drives the belt and gear to transfer power to the paper cutter. Some paper shredders on the market can select two or more paper shredding modes. Different paper shredding modes are suitable for different occasions, and if the paper shredding mode is a general office occasion, the paper shredding mode can be selected to be segment, granular, filiform or strip. However, if the foam is used in some occasions with higher requirements on confidentiality, the foam is necessarily used. The paper shredding mode that adopts four swoves to constitute at present is the most advanced working method, and the paper grain of shredded paper is neatly fallen, can reach secret effect. The cutting principle of the paper shredder is that the blades or the cutters are arranged in a staggered mode, and paper is torn under the action of a power source. If the knife or blade is provided with a knife tip, the effect of shredding is segment-like or granular, and if the knife or blade is provided without a knife tip, the effect is strip-like.

But the recovery treatment of the broken paper scraps in the later period is troublesome, on one hand, loose paper scraps are inconvenient to carry, on the other hand, the density of the fluffy and piled waste paper scraps is small, the occupied space is large, the waste paper scraps are uniformly collected, the space is also easy to cause scattering and messy, therefore, when the paper scrap storage box of the paper shredder is full, people usually mix the paper scrap storage box with other garbage and discard the paper scrap storage box due to the small quantity of the paper scrap storage box, the recycling efficiency is low, the waste of paper resources is caused, objects are generally compressed by a pneumatic device or a hydraulic device, the most effective effect can be obtained, but the paper shredder is usually applied in office places, and the pneumatic device and the hydraulic mechanism need to be provided with an additional power device, an air pump and an oil cylinder, which not only increases the volume and is inconvenient to arrange, but also has overlarge noise, therefore, it is impractical to provide a crusher that can achieve a good compression process even when using low-power electricity at home as power.
