Horizontal cutting knife and paper shredding knife

Abstract

The invention provides a horizontal cutting knife which comprises a fixed frame, a static knife board and a dynamic knife board, wherein the static knife board and the dynamic knife board are fixedly arranged on the fixed frame; the dynamic knife board is matched with the static knife board; the dynamic knife board is provided with a first connecting end and a second connecting end; the first connecting end and the second connecting end are respectively movably connected to the fixed frame; when a medium is cut, the first connecting end moves along a first track, and the second connecting end moves along a second track at the same time; the first track comprises an arc-shaped section or a straight-line section which is inclined relative to an edge of the static knife board; the second track is matched with the first track in a linked way. The horizontal cutting knife provided by the invention has the advantages of simple structure and low cost; according to the horizontal cutting knife, when paper is cut, the dynamic knife board moves up and down relative to the static knife board so as to cut the medium and simultaneously moves left and right relative to the static knife board so as to cut the medium, so that the labor conservation in cutting is achieved. In addition, the invention also discloses a paper shredding knife.

Description

technical field [0001] The invention relates to the field of cutters, in particular to a cutting cutter for laterally cutting media. Background technique [0002] With the rapid development of knowledge today, people's awareness of confidentiality is getting stronger and stronger. In daily life or work, there are often documents and other media that need to be destroyed, so as to prevent others from obtaining the information recorded on the document. Correspondingly, all kinds of discarded paper technical materials should be shredded before being thrown away as garbage. Different shredding methods are suitable for different occasions. If it is a general office occasion, you can choose segmental, granular, filamentary, or strip-like. But if it is used in some occasions that require high confidentiality, it must use foam. So at present, various paper shredders are widely used in offices. The paper shredder mainly uses groups of shredding blades fixed on two parallel and re...

Problems solved by technology

However, the paper at the end of this shredding mechanism cannot be effectively shredded into small particles, and the confidentiality is not good. The horizontal shredding mechanism can be a spiral shredding cutter formed by a combination of a spiral knife and a fixed knife, or a guillotine cutting tool formed by a combination of a moving knife and a static knife. However, the spiral knife not only costs High, and the confidentiality of shredded paper is still not good. Although the cost of the guillotine cutter is low, it is laborious to shred paper
