Description

Technical Field

[0001] This invention belongs to the field of testing technology for aluminum two-piece can printing machines, specifically relating to a device and method for detecting wear on the ink hopper support of an aluminum two-piece can printing machine. Background Technology

[0002] Currently, the ink hopper of aluminum two-piece can printing presses is mounted on the printing press frame via a fixed shaft, support arm, and other mechanisms, referring to... Figure 8 and Figure 9 As shown, due to collisions and friction during the disassembly or installation of the ink fountain in the printing press, as well as vibrations generated during the printing press's operation, the support will wear down over time. This causes the ink fountain's fixed shaft to become misaligned, resulting in inconsistent pressure between the ink fountain's plate shaft and the front and rear ends of the tape turntable. Consequently, printing defects such as uneven color depth, missing prints, or ink smearing occur on the cans. During repairs, the gap is usually eliminated by adding shims or replacing the support. However, since replacing the support is time-consuming and labor-intensive, adding shims is generally considered as a temporary fix. Due to a lack of testing methods, the thickness of the shims is usually determined based on the repair personnel's experience and the printing condition of the product, making it difficult to determine the correct thickness the first time and affecting daily maintenance work.
