a thermal printer

Abstract

The present invention relates to the technical field of printer equipment, in particular to a thermal printer, comprising a printer casing and a receiving device, the receiving device is movably plugged into the side of the printer casing, and the side end surface of the printer casing is opened There is a first insertion slot, and limit slides are provided on both sides of the inner bottom surface of the first insertion slot, grooves are symmetrically opened on the edge of one end surface of the first insertion slot, and the top of the printer casing An extruding block is movably inserted on the edge of one end of the surface, and a heat dissipation hole is opened in the center of the top surface of the printer casing, and an outlet is opened on the top surface of the printer casing and located at the edge of the heat dissipation hole. An operation panel is fixedly installed on the end surface, a receiving base is fixedly installed inside the receiving device, and a limiting device is installed movable inside the receiving base. The present invention can expand the installation space of the label roll by pulling out the receiving base, which is convenient for workers to install the label roll.

Description

technical field [0001] The invention relates to the technical field of printer equipment, in particular to a 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. It is produced by a chemical reaction in the film, and the chemical reaction of this thermal printer is carried out at a certain temperature. High temperatures accelerate this chemical reaction, and at 200°C, the reaction completes within microseconds. [0003] At present, with the rapid development of technology, the volume of thermal label printers is getting smaller and smaller. When using thermal label printers, the label roll needs to be installed inside the thermal label printer, and then heated at high temperature to make the image ...

Problems solved by technology

[0003] At present, with the rapid development of technology, the volume of thermal label printers is getting smaller and smaller. When using thermal label printers, the label roll needs to be installed inside the thermal label printer, and then heated at high temperature to make the image printed on the label surface, so as to complete the label printing, but when the existing thermal label printer installs the label, due to the small size of the printer and the small installation space inside the printer, it is not convenient for the staff to quickly install the label , so a thermal printer is needed to solve the problems raised in the above
