Description

Technical Field

[0001] The utility model belongs to the technical field of printer cutting, in particular to a printer paper cutting device. Background Art

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on related media. There are many types of printers. According to whether the printing element hits the paper, they are divided into impact printers and non-impact printers; according to the structure of printed characters, they are divided into full-width character printers and dot matrix character printers; according to the way a line of characters is formed on paper, they are divided into serial printers and line printers; according to the technology used, they are divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers.

[0003] Currently, the printed engineering drawings are on papers of different sizes, including various specifications. Therefore, during the printing process of engineering drawings, the paper needs to be cut according to actual needs. The current cutting method is mostly manual cutting. During manual cutting, the paper is mostly pressed down by an object, and then cut with a utility knife. In this way, the cut edges of the paper are uneven, and it is easy to accidentally damage the paper. Most engineering drawings cannot be damaged. Utility Model Content

[0004] The utility model aims to provide a printer paper cutting device, which provides a movable cutting knife, specifically, pulls up a movable plug rod and pushes a push rod. Because the push rod and the cutting knife head are both conical, when the push rod is pushed, the cutting knife will be pressed down, causing the knife head to leak out. The movable plug rod is lowered by the protrusion of the movable plug rod head, stuck in the groove provided by the push rod and the cutting knife, and fixed. Then the cutting knife is pushed to complete the cutting of the paper, which solves the problem that the paper needs to be cut according to actual needs during the printing of engineering drawings. The current cutting method is mostly manual cutting. When manual cutting is performed, the paper is mostly pressed down by an object, and then a utility knife is used to cut. In this way, the cutting edge of the cut paper is uneven, and it is easy to accidentally scratch the paper, and the engineering drawings cannot be damaged.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
