Problems solved by technology

[0011] The technical problem to be solved by the present invention is to solve the problem of slow printing speed, high energy consumption required for printing, large wear of the print head and print head wear and tear due to the use of "heat conduction" in the prior art to transfer heat energy to the printing consumables. To solve the problem of high manufacturing cost and difficulty, a new thermal print head is provided, which can transfer heat energy to printing consumables in the form of infrared radiation, thereby effectively increasing the printing speed and greatly reducing printing energy consumption. Mechanical wear and tear and manufacturing difficulty and cost of thermal printheads

Abstract

The invention discloses a thermosensitive printing head. The thermosensitive printing head comprises an infrared radiation layer, and the infrared radiation layer is made of an infrared radiation material and used for radiating heat to a printing medium in a thermal radiation mode. According to the thermosensitive printing head, printing consumables can be heated in an infrared radiation mode, therefore, through the infrared radiation heating characteristics that the penetrating power is high, internal heating and external heating can be simultaneously conducted, the heating speed is high, noheat transfer medium is needed for transferring, the heat efficiency is good, and a heated object can reach the temperature similar to that of an infrared radiation source in a short time when the infrared ray absorption rate of the heated object is high enough, the printing speed is effectively increased, and printing energy consumption, mechanical losses of the thermosensitive printing head andthe manufacture difficulty and cost of the thermosensitive printing head are significantly reduced.

Description

[0001] This application is a divisional application based on the original application with the application number 201710165253.8, the application date is March 20, 2017, and the invention name is "thermal print head". technical field [0002] The present invention relates to the field of printing equipment, in particular to a thermal print head for thermal and thermal transfer printing, and more specifically, to a thermal print head that transmits thermal energy required for printing in the form of infrared radiation. Background technique [0003] Both thermal printing and thermal transfer printing methods use a thermal print head to heat the surface of printing consumables to achieve printing. The thermal printing method does not use a carbon ribbon, and the thermal print head directly heats the thermally sensitive components on the surface of the thermal printing medium to develop color and then prints out the corresponding pattern. Therefore, there is only one kind of prin...
