DETAILED DESCRIPTION

[0046] Various exemplary embodiments, features, and aspects of the present application will be described herein below with reference to the accompanying drawings. The same reference numbers in different drawings represent the same or similar elements or components. Although various aspects of the embodiments are illustrated in the drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0047] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0048] In addition, for the purpose of convenience and brevity, detailed descriptions of well-known methods, apparatuses, materials and / or components are omitted so as to avoid obscuring the teachings of the present application. In some instances, methods, apparatuses, components, and / or elements known in the art have not been described in detail in order to avoid obscuring the teachings of the present application.

[0049] Please refer to Figures 1-4 In the embodiment of the present application, a movable ink delivery roller device of a gravure printing machine comprises an ink table 1 and an ink tank 5 mounted on the ink table 1, a support structure, a lifting mechanism, an ink delivery roller 6, a lifting piece and a driving piece, wherein:
