Abstract

The invention discloses a plane printing roller and relates to a needle type printer. The plane printing roller comprises two rubber layers and a solid metal layer, wherein the two rubber layers and the solid metal layer are bonded together through two elastic buffering layers. The thickness of each rubber layer is 2-3mm. Printing planes are arranged at the ends, far away from the elastic buffering layers, of the rubber layers. Inclined planes are arranged at two sides of the printing planes. The rubber layers and the elastic buffering layers are arranged symmetrically with respect to the solid metal layer. Mounting heads are fixedly connected with the two sides of the solid metal layer and are connected with an external printer frame. The plane printing roller can solve the problems thata large amount of noise is generated, the printing quality is poor, and outer-layer rubber needs to be replaced integrally due to partial damage when a needle type printer works in the prior art.

Description

technical field [0001] The invention relates to a dot matrix printer, in particular to a plane printing roller of a dot matrix printer. Background technique [0002] The working principle of the dot matrix printer is: first put the paper on the printing roller, rely on the printing needle of the dot matrix print head to hit the ribbon, and print the ink on the surface of the ribbon on the paper, and the printing roller actually plays a role in the printing process. As a support for the paper, every time the printing needle hits the ribbon, it will force the local deformation of the paper and impact and friction with the printing roller. In the traditional dot matrix printer, the printing roller is generally composed of an outer rubber ring and an inner rubber ring. It is made of a hollow circular metal pipe, and the sound generated by impact and friction will echo continuously inside the hollow pipe, so a lot of noise will be formed; the rubber on the outer layer of the prin...
