Printer

Abstract

The invention discloses a printer, comprising a main frame, a first moving frame, a second moving frame, a split cutter which is composed of a moving blade and a shear blade, a first fixed apparatus which is positioned on the sidewall of the second moving frame, and a second fixed apparatus which is positioned on the sidewall of the main frame. The moving blade and the shear blade are respectively fixed on the first and the second moving frames. The first and the second moving frames are respectively hinged on both sides of the main frame through rotating shafts. The first fixed apparatus andthe second fixed apparatus are respectively arranged on both sides of the cutter edges, wherein, the first fixed apparatus is positioned on a side near the moving blade, and is used to limit the displacement of the second moving frame corresponding with the main frame while cutting the paper; the second fixed apparatus is positioned on a side near to the shear blade, and is used to limit the rotation of the second moving frame corresponding with the main frame. The printer has the advantages of adding to the location stability of the shear blade while cutting the paper, and prolonging the service life of the cutter.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printer with split cutters. Background technique [0002] Commonly used dot-matrix printers use the needles of the print head to print the ink on the ink ribbon opposite to the print medium to form images or characters. At present, in order to improve the printing function and improve the printing efficiency, there are a large number of printers with an automatic cutting mechanism on the market, which can automatically cut the printing medium through the automatic cutting mechanism after printing is completed. [0003] like figure 1 As shown, a "printer" disclosed in Chinese patent CN03148992 has a structure as follows: the fixed frame 12 of the printer supports the print head 20, the movable frame 13 supports the paper support member 55, and the movable frame 13 is supported by the fixed frame 12 Support, and rotate relative to the fixed frame 12 through the hinge shaft.

AI Technical Summary

Problems solved by technology

[0004] However, there are at least the following problems in the prior art: since the fixed blade 31 is fixed between the first passage 15 and the second passage 36, this makes After opening the printer casing, the print head 20 and the paper support member 55 cannot be fully exposed, thereby reducing the maintainability of the printer

[0006] However, this technology has at least the following problems: since the fixed blade bracket 3 is hinged to the printer main body 1, it can rotate along the hinge axis, which will cause the fixed blade 31 Unstable position

Thereby, the precise and stable positional relationship between the fixed blade 31 and the movable blade 21 will be affected when paper is cut, thereby affecting the stability and reliability of the paper cutting by the cutter. The relative position of the movable blade 21 is unstable when cutting paper, which will cause the blade to wear due to excessive friction between the blade and the paper, thus reducing the service life of the cutter
