Document Type and Number:
WIPO Patent Application WO/2024/016599
Kind Code:
A1
Abstract:
A print head assembly (10) with a deflection angle, comprising a print head tray (11) and print heads (12), wherein the print heads are distributed side-by-side in several rows on the print head tray, print heads in two adjacent rows are staggered and overlap with each other, and the print heads are obliquely mounted relative to the print head tray; and the several rows of print heads are arranged around an arc-shaped print face, lower surfaces of the several rows of print heads are combined to form a concave ink-jet surface, and each face of the ink-jet surface is tangent to the arc-shaped print surface. Further disclosed is a printing device, comprising a roller (30), a linear moving assembly (40), and the print head assembly, wherein the roller is configured to wind and feed a print medium; and the linear moving assembly is configured to drive the print head assembly so as to adjust the distance between the print head assembly and the surface of the roller. The print head assembly solves the problem that several rows of staggered and overlapping print heads cannot be perpendicular to the arc-shaped print surface at the same time, thereby improving the overall printing quality.
