Description

Technical Field

[0001] The utility model relates to the technical field of paper cutting machines, and more specifically, it relates to a paper cutting machine with adjustable cutting distance. Background Technique

[0002] When a paper cutting machine cuts paper, some cut perpendicular to the paper feeding direction to cut a paper roll into sheets of paper, while some cut along the paper feeding direction to cut a paper roll into narrower paper rolls. When the latter cuts, multiple cutting knives are provided, and the distance between the cutting knives is the cutting distance. At present, the cutting distance in most cutting devices is not easy to adjust, so it is not easy to adjust the width of each paper roll after cutting at will; in addition, the cutting knives in the existing cutting machines are fixed and correspond to the positions to be cut of the paper. The paper is driven by an external paper feeding mechanism for conveying. When the paper passes through the cutting knives, it is cut into two parts by the cutting knives, and these two parts continue to be conveyed until they are wound on different paper rolls later to achieve paper cutting. However, at this time, a certain part of the cutting edge of the cutting knife is used for cutting for a long time, resulting in easy chipping and wear at this position of the cutting knife. When it is not sharp enough, burrs or breakage will occur at the cutting position of the paper, affecting the cutting quality. Content of the Utility Model
