Thermal head heating adjusting device, thermal head heating adjusting method and thermal printer

Abstract

The invention provides a thermal head heating adjusting device, a thermal head heating adjusting method and a thermal printer. The thermal head heating adjusting device comprises a thermal head module, a paper bin internal environmental temperature acquisition module, a thermal head body temperature acquisition module and a master control module. The thermal head heating adjusting device, the thermal head heating adjusting method and the thermal printer have the advantages that temperature sensors in a paper bin of equipment are matched with a built-in thermistor of a thermal head and are combined with the built-in thermistor of the thermal head, the design is perfect, the automatic thermal head heating control accuracy is high, and accordingly the thermal printer can clearly print data for a long time.

Description

technical field [0001] The invention relates to the field of printers, in particular to a thermal head heating adjustment device and method and a thermal printer. Background technique [0002] Thermal printer technology was first used on fax machines. With the development of thermal printer technology, it has been popularized in POS terminal systems, banking systems and other fields. Because thermal printers have the advantages of low noise, fast speed, high reliability, clear printing characters, and miniaturization, they have also been widely used in the field of medical instruments, mainly in electrocardiographs, monitors, and inspection instruments. Print test data, waveforms, etc. [0003] The basic principle of a thermal printer is that the processor of the main device sends the data to be printed to the thermal printer, and the thermal printer converts the data into a dot matrix signal of the thermal head after receiving the data, and then controls the heating of the...

Problems solved by technology

The printing process in the whole high-temperature environment will appear: the printed graphics are too dark, and the action of printing a section and entering the protection repeatedly occurs, which affects the actual use effect. The equipment reduces the number of doctors checking patients and affects the doctor's work efficiency.

[0009] In summary, due to the immaturity of previous technologies, the heating time of thermal printers has not been adjusted accordingly for changes in ambient temperature, resulting in blurred and unclear printed images and texts in low-temperature environments, which affects doctors' viewing of test data; in high-temperature environments , the printed text is darker, the temperature of the thermal head is too high, and it enters the overheating protection sooner, which affects the number of patients that doctors use the equipment to check, and affects the work efficiency of doctors
