Technical Field

[0001] The utility model relates to the technical field of printing, and more specifically to a water-based ink gravure printing plate roller. Background Art

[0002] Gravure printing is one of the most common basic printing methods in the printing field. It is a printing method that uses gravure printing. In gravure printing, the blank part on the printing plate is higher than the printed image part, and the height difference is large. The blank part is located on the same plane or the same curved surface, and the concave image part forms a mesh to hold the ink. Through the effect of printing pressure, the image imprint is transferred to the surface of the substrate.

[0003] The gravure plate roller is generally an integrated structure of the shaft and roller, which is inconvenient to transport and store. In the prior art, some gravure plate rollers with a detachable plate roller and inner shaft have appeared, but the inner shaft can only adapt to the plate roller with a fixed axial size. Due to the large size differences such as the width of the printing plate during the printing process, when printing a local pattern with a smaller width, a longer plate shaft is still used as the bearing substrate, which undoubtedly consumes a lot of printing equipment investment costs and has poor economic efficiency. Utility Model Content

DETAILED DESCRIPTION

[0017] The utility model is described in detail below in conjunction with the accompanying drawings.

[0018] Specific embodiment 1 of a water-based ink gravure printing plate roller of the utility model:

[0019] like Figure 1 As shown, the water-based ink gravure plate roller comprises an inner shaft 1 and a plate roller 2 sleeved on the outer side of the inner shaft 1. The outer side of the inner shaft 1 is also sleeved with fixed plugging sleeves 3 located at both ends of the plate roller 2. The plate roller 2 is positioned and fixed on the inner shaft 1 through the fixed plugging sleeves 3 at both ends. Two groups of adjustable threaded holes 4 are symmetrically opened at both ends of the inner shaft 1, and each group of adjustable threaded holes 4 is provided with at least two.
