Paper shredder for teaching and office

Abstract

The invention discloses a paper shredder for the teaching and office. The paper shredder comprises a base. A cushion is arranged in the base. A processing cavity is formed in the middle end in the cushion. An electric control box is arranged at the upper end of the right side of the processing cavity. A paper input opening is formed in the upper side of the processing cavity. A first breaking cavity is formed in the lower side of the paper input opening. A connecting cavity is formed in the left side of the first breaking cavity. A discharging pipe is arranged on the lower side of the first breaking cavity. A second breaking cavity is formed in the lower side of the discharging pipe. Sealing cavities are correspondingly formed in the left side and the right side of the second breaking cavity. A mixing cavity is formed in the lower side of the second breaking cavity. A water storage cavity is formed in the left side of the mixing cavity. A water adding opening is formed in the upper side of the water storage cavity. A water pumping pipe is arranged at the right end of the water storage cavity. A drainage pipe is arranged on the right side of the mixing cavity. A filter cavity is formed in the right side of the drainage pipe. A filter net is arranged in the filter cavity. A connecting pipe is arranged between the filter cavity and the water storage cavity. A connecting pump is arranged on the connecting pipe. By the adoption of the paper shredder for the teaching and office, the paper can be effectively shredded twice, so that the paper shredding efficiency of the equipment can be guaranteed effectively, and treatment of shredded paper is facilitated.

Description

technical field [0001] The invention relates to a teaching device, in particular to a paper shredder for teaching and office use. Background technique [0002] Teaching instruments and equipment refer to the instruments and equipment used in teaching and scientific research units with a unit price of 800 yuan or more and used for teaching or scientific research. Teaching instruments can be divided into two categories: experiments and practical training, which are mainly used in various majors of science and engineering. Among them, the shredder is a general type of teaching equipment. A shredder consists of a set of rotating blades, a comb and a drive motor. The paper is fed from the middle of the interlocking blades and is divided into many small pieces of paper to achieve the purpose of confidentiality. The shredding method refers to the shape of paper shredded by a shredder knife after being processed by a shredder. According to the composition of the shredder knife, ...

Problems solved by technology

[0003] However, the current paper shredders are generally processed through a layer of crushing equipment, which often makes the shredded paper not small enough, and the shredding efficiency is very low, and it is very inconvenient to handle the paper after the equipment is shredded. In addition, during the shredding process of the equipment, Generate vibration, which not only produces noise pollution, but also affects the service life of the equipment
