Annular printing device and printing method

Abstract

The invention provides an annular type printing device, comprising a printing component and a locating mechanism, which is characterized in that: the printing device can print awaiting print thing with curved surface in circle; the printing component is arranged on the annular guide way and is composed of a printing material box; the locating mechanism comprises a housing space, a sliding seat, apole support and a locating bar at least; wherein the housing space is used to store an awaiting print thing; the sliding seat is arranged at the end of the housing space and is provided with a elastic element; one end of the pole support is connected with the bottom of the sliding seat and the other end is connected with the locating bar; when the locating bar is pushed ahead, under the interdependent function, the pole support pushes up the sliding seat, and then the elastic element reaches to the awaiting print thing to fulfill locating; wherein the annular guide way is surrounded by the locating mechanism to make the printing component can print the awaiting print thing in circle after locating.

Description

technical field [0001] The present invention relates to a printing device, in particular to a circular printing device, which is applicable to printing curved surface objects. Background technique [0002] With the increasing diversification of technological development, the functions of printing devices are also developing towards more changes following the trend. Because traditional printing devices are mainly used in offices and do not have other varied functions, as long as printing devices are mentioned, it is easy to directly think of inkjet printers, toner printers, photocopiers, and fax machines. Traditional printing devices have a common feature, that is, the objects that can be printed are all flat objects, such as ordinary paper, advertisement leaflets, large pictures or posters. [0003] Therefore, in order to cooperate with the design of the traditional printing device, if printing on objects with curved surfaces, the method usually adopted is to first put the ...

AI Technical Summary

Problems solved by technology

The printing trajectory T1 of the traditional printing device is straight, and the surface S1 of the object A to be printed is arc-shaped. Therefore, when printing an object with a curved surface, it still cannot match the curvature of the curved surface, and the perfect printing quality cannot always be achieved. , especially at the two ends of the curved surface object, because the curved surface is relatively large, it often cannot be printed or the pattern overlaps
