Abstract

The utility model discloses a thermal print head comprising a base plate made from insulating material. A ground coat layer is formed on part of or all the surface of the base plate; electrode leads and resistance heaters which are supplied with power through the electrode leads are formed on the surface of the ground coat layer or the base plate; a resistance belt is formed by the resistance heaters; and the resistance heaters and the electrode leads which are connected with the resistance heaters are at least partially covered by protection layers. The thermal print head is characterized inthat one side of each resistance heaters is provided with a printing paper pre-grinding layer. When a thermal printer works, the printing paper is fully pre-ground on the printing paper pre-grinding layer under the drive of the pressure and the rotary drawing force of a rubber-covered roller so that the rough surface of the printing paper is subjected to the similar 'polishing'treatment. When theprinting paper which is subjected to the similar'polishing' treatment on the surface is printed after contacting the protection layers covered on the surfaces of the resistance heaters, the wear of the protection layer of the thermal print head is alleviated, and the wear-resistance distance of the thermal print head is prolonged, thus the thermal print head can print on a piece of rough paper. The utility model has the advantages of simple structure, easy implementation, low printing cost, long running service and the like.
