Embodiment 2

[0069] Embodiment 2 Contact thermal baking printing method (principle-based example)

[0070] The process flow of the contact thermal baking printing method is as follows: figure 1 shown. It inherits the basic flow of printing data transmission 1, energy supply 2, electromechanical control system 3, printing head 4, printing head movement process 5, printing paper (paper feeding device) 6, etc. in the current printing method. But innovations were made to the print head. It includes: the heating process of the heating element, the action process of the relevant parts that contact the printing paper, and the process of discoloring the surface of the printing paper through high temperature to form characters or patterns. Printheads can be divided into two categories, they are respectively based on the printheads of existing dot matrix printers and thermal printers, by adding high-temperature thermistors and temperature control devices, etc., and then carrying out corresponding ...

Embodiment 3

[0071] Embodiment 3 A collectively heated needle-type thermal baking print head device

[0072] Figure 7 Shown is a structural schematic diagram of the core part of a collectively heated double-circle pin type thermal baking print head device. Its basic structure and principle are similar to Figure 4 The improvement of the double-circle dot print head of b is as follows: firstly, in terms of materials, it needs to be made of high-temperature-resistant materials; secondly, Figure 4 As shown in a, when the printing needle passes through the positioning plate 10 from the root, it directly passes through the position of the center of the corresponding small hole of the positioning plate, without contacting the positioning plate-current printers need to pass through contact, so that if Figure 5 The needles shown in a were originally arranged in a circle, through Figure 5 The guidance of the positioning plate or guide plate from top to bottom shown in c, finally forming two ...

Embodiment 4

[0073] Figure 8 Shown is a structural schematic diagram of the core part of a double-circle needle type thermal printing head device for each printing needle. Its basic structure and principle are similar to Figure 7 , the improvement is: replace the collective heating plate 13 with the heat insulating plate 12, each printing needle can be heated by electrifying itself, and then according to the printing data information, heat the printing needle that needs to be printed, and let it complete the printing at the same time action. At this time, the temperature of the non-printing printing needles will drop greatly, so compared with the way of collective heating, the heat insulation requirements will be lower. When not printing, there needs to be a certain distance between the tip of the needle tip and the printing paper, usually 0.2-1mm.

Abstract

The invention discloses an inkless ecological hot baking printing method and a printing head device. Ordinary printing paper is used, a printing head and the paper adopts either a direct contact mode or a non-direct contact mode. The inkless ecological hot baking printing method and the printing head device are characterized in that a heating element is arranged on the printing head, the color ofthe surface layer of the printing paper is changed through the heat energy of the printing head, so characters or patterns are formed. During the direct contact, the temperature of the printing head is set into 100 to 1000 DEG C, the stop time of the printing head is 0.1 to 100 ms, during the non-direct contact, the temperature of the printing head is set into 200 to 1000 DEG C, and the stop timeof the printing head is 0.1 to 100 ms. Ink powder or ink or paint is not needed, the printing effect can be reached through hot baking by only adopting the single ordinary printing paper, and good low-carbon energy-saving effects and social benefits are realized.

Description

technical field [0001] The invention relates to an ink-free ecological printing and printing technology, in particular to a thermal baking printing method, which can be applied to printing devices such as office, household or industrial printers, printing machines, copiers, fax machines and all-in-one machines. Background technique [0002] With the development of science and technology and the improvement of people's living standards, printing devices such as printers have become an indispensable device in the offices of enterprises and institutions, and have also become common articles for many families. [0003] At present, in addition to 3D printing technology, printers can be mainly divided into four categories: laser, inkjet, dot matrix and thermal printing in terms of printing principles. Among them, thermal printers are mainly used to print labels and barcodes, dot matrix printers are mainly used in special fields such as printing bills, while laser and inkjet printe...
