Embodiment 1

[0031] Such as Figure 1-2 As shown, this embodiment provides a print head assembly, including at least two print heads that are spliced ​​transversely in the printing width direction, and share the same print axis 7, and the thermal heating lines of at least two of the print heads are parallel They are arranged at intervals along the printing direction on the plane of the substrate and spliced ​​horizontally. In this embodiment, at least two of the print heads are the first print head 4, the second print head 5, and the third print head 6 that are sequentially spliced ​​horizontally along the printing width direction, and the first print head 4 of the first print head 4 The thermosensitive heating lines 1, the second thermosensitive heating lines 2 of the second print head 5 and the third thermosensitive heating lines 3 of the third print head 6 are arranged alternately, that is, they are overlapped and spliced ​​in the transverse direction. Further, the splicing surfaces of...

Embodiment 2

[0039] This embodiment provides a thermal transfer printer, including the print head assembly described in Embodiment 1, and also includes a drive assembly for driving the print head assembly to move, the drive assembly is a motor, and there is only one, one It only needs to connect the output shaft of the motor to the printing shaft 7 of the print head assembly, which reduces the cost.

Embodiment 3

[0041] This embodiment provides a printing method using the thermal transfer printer in Embodiment 2, including: the drive assembly drives three print heads to press down to the position to be printed on the paper at the same time; Corresponding images are output sequentially at intervals, that is, the first print head 4 at the front of printing outputs images first, and the second print head 5 and third print head 6 at the rear output images sequentially, thereby completing image horizontal splicing. In this embodiment, the predetermined time interval is the ratio of the distance between the thermally sensitive heating lines of two adjacent print heads to the printing speed.

[0042] In this embodiment, since the printing surfaces of two adjacent print heads are inclined planes, and the pixels of the printing areas on the inclined planes overlap, when printing, the left side of the second printing head is controlled to output overlapping pixel images, while The right side of ...

Abstract

The present invention relates to the technical field of printers and in particular to a print head assembly, a thermal transfer printer having the same, and a printing method. The print head assemblyincludes at least two print heads laterally spliced in a print width direction and sharing the same print shaft. The thermo-sensitive heating lines of the at least two print heads are laterally spliced at intervals in a print direction on a plane parallel to a print material. The print head assembly of the present invention is low in cost and relatively fast in print speed. A print ribbon and paper are less likely to wrinkle and paper is less likely to jam.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a print head assembly, a thermal transfer printer with the same and a printing method. Background technique [0002] The working principle of the thermal transfer printer is to use a special carbon ribbon, and through the working principle of the thermal print head, the toner coating on the carbon ribbon is transferred to paper or other types of materials by heating. The carbon ribbon is on the thermal transfer printer, the heat-resistant coating is in direct contact with the thermal print head, and the thermal transfer ink is in direct contact with the substrate (paper or other types of materials). The heat of the hot spot is transmitted to the thermal transfer ink coating through the heat-resistant coating and the base film, and the ink is melted and stamped onto the substrate to form text and images. Thermal transfer printers use carbon ribbons to transfer printing. There is...
