Convenient-to-use thermal printer

Abstract

The invention discloses a convenient-to-use thermal printer. The thermal printer comprises a printer housing, wherein a fixed seat is fixed on an outer wall of the printer housing; a control panel isarranged at the upper end of the printer housing; a printing head is arranged in the printer housing, and a printing paper fixing housing is clamped at the upper part of the printer housing; shiftingblocks are arranged at two ends of the printing head, a second spring is arranged at the inner side of each shifting block, and a positioning seat is fixed to one end of each second spring and fixed to an inner wall of the printer housing; a printing paper fixing rod is arranged at the inner side of the printing paper fixing housing; a fixing button is arranged on the outer wall of the printing paper fixing housing in a penetrating manner; and paper guide wheels are arranged at the inner side of the printing paper fixing housing. The convenient-to-use thermal printer is provided with a clamping structure, so that mounting work of printing paper is facilitated, the size of the thermal printer is small, and carrying work of the thermal printer is facilitated.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to an easy-to-use thermal printer. Background technique [0002] The working principle of a thermal printer is that a semiconductor heating element is installed on the print head. After the print head is heated and contacts the thermal printing paper, the required pattern can be printed out. The principle is similar to that of a thermal fax machine. Produced by a chemical reaction in the film, this thermal printer chemical reaction is carried out at a certain temperature, high temperature will accelerate this chemical reaction, when the temperature is lower than 60 ° C, the paper needs to go through a long, even long It takes several years to turn into a dark color, and when the temperature is 200°C, this reaction will be completed within a few microseconds. [0003] Most of the body modules and chassis of existing thermal printers are fixed, and it takes time and effort to disass...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an easy-to-use thermal printer to solve the problem that the body modules and the chassis of the thermal printer proposed in the background technology are mostly fixed, and the dismantling of the chassis and the body module during the maintenance and repair process of the machine is solved. It is time-consuming and laborious to solve and install, the efficiency is low, it is very inconvenient, and it is very inconvenient to set the printing paper at the same time
