Description

Technical Field

[0001] The utility model belongs to the technical field of print head components of label printers, and in particular relates to a print head fixing structure of a wide-format printer. Background Art

[0002] Wide-format printers usually refer to printers that can print wide-format fabrics. They are widely used in advertising, decoration, clothing, logos, packaging and other fields. Wide-format printers are characterized by their ability to print larger materials. Common printing widths range from 1 meter to 3 meters, or even wider, to meet printing needs of different sizes.

[0003] The print head assembly of existing wide-format thermal transfer printers generally includes a print head, a print head bracket, a spring and a spring support frame. The wide-format print head assembly is much larger than the two- or three-inch print head assembly, which is mainly reflected in the thickness of the print head bracket and the thickness of the spring support frame. The wider print head requires greater spring force, and a thicker thickness is required to ensure that the print head and the spring support frame will not be deformed due to the greater spring force, because deformation will cause unclear printing in the middle, especially when printing harder paper such as aluminum foil, which requires greater spring force. Therefore, it is currently a contradiction to reduce the size of the print head assembly on a wide-format portable machine without sacrificing print quality. Utility Model Content
