AI Technical Summary

Technical Problem

Existing high-speed printers cannot pre-spread ink before printing, resulting in incomplete printing and difficulty in controlling ink output, which affects print quality and wastes paper.

Method used

A roller ink control and adjustment system was designed, including an ink distribution mechanism, a drive component, and a spacing adjustment component. The drive component makes the ink roller fit tightly against the inner wall of the printing roller, and the spacing adjustment component adjusts the spacing between the ink distribution roller and the ink roller to achieve pre-ink distribution and stable ink output.

Benefits of technology

It avoids printing defects in the early stages of printing, ensures printing quality, and maintains stable ink output under different ambient temperatures, reducing ink waste.

Abstract

This invention provides a roller ink control and adjustment system: it includes a printing roller rotatably connected to a frame, and an ink-spreading mechanism inside the printing roller for spreading ink evenly. The ink-spreading mechanism includes a mounting bracket, an ink-spreading roller, an ink roller, and a drive assembly. The mounting bracket is connected to the frame, and the ink-spreading roller and ink roller are rotatably connected to the mounting bracket. The ink-spreading roller and ink roller are arranged parallel to each other, and an ink storage tank for accommodating ink is formed between them. The drive assembly is connected to the frame and is used to push the mounting bracket so that the outer peripheral wall of the ink roller on the mounting bracket abuts against the inner peripheral wall of the printing roller. Before printing, this invention can push the mounting bracket with the drive assembly so that the outer peripheral wall of the ink roller on the mounting bracket abuts against the inner peripheral wall of the printing roller. Then, the printing roller rotates to pre-spread ink on its inner peripheral wall before printing begins, avoiding printing defects on the first few sheets.
