AI Technical Summary
Technical Problem
In existing sheet-fed gravure printing machines, the ink cylinder experiences unstable viscosity due to ink sedimentation during use, which easily leads to ink streaking, reduces printing quality, and affects production efficiency. Furthermore, the stirring device requires electric power, increasing production costs.
Method used
Multiple baffles and guide holes are installed inside the ink cylinder. Combined with a rotating shaft and a stirring shaft, the ink flowability is optimized. The ink is evenly distributed through automatic flow or motor drive, avoiding sedimentation and stratification.
Benefits of technology
It improved printing quality, reduced streaking, saved energy, increased production efficiency, and reduced production costs.

Abstract
The utility model discloses an ink cylinder for a sheet-fed gravure press, which comprises a cylinder body, a first partition plate is arranged in the cylinder body, the cylinder body is divided into an ink inlet cylinder body and an ink outlet cylinder body by the first partition plate, and a first flow guide hole communicated with the ink inlet cylinder body and the ink outlet cylinder body is arranged at the bottom of the first partition plate; compared with the prior art, the ink tank has the advantages that the flowability of ink in the tank body is improved through the arrangement of the first partition plate, in the using process, along with the reduction of the amount of the ink in the ink outlet tank body, the ink in the ink inlet tank body can be automatically supplemented into the ink outlet tank body, along with the flowing of the ink, precipitation layering generated in the standing process of the ink tank body is reduced, and the printing quality is improved.
