At this time, the side scraping plate 52 abuts against the inner side surface of the dispersion barrel 3, and the bottom scraping plate 55 abuts against the inner bottom surface of the dispersion barrel 3. Finally, start the first driving motor 6 to drive the central column 51 to rotate, and the side scraping plate 52 and the bottom scraping plate 55 rotate, simultaneously driving a plurality of horizontal stirring paddles 53 and a plurality of vertical stirring paddles 56 to rotate, so as to stir and disperse the ink. After the dispersion is completed, the material is discharged through the discharge nozzle 31. The structural form of the stirring mechanism 5 of the present utility model can more fully stir and disperse the ink at different positions, with higher stirring efficiency and more uniform dispersion. While stirring the ink, it can also scrape off the ink adhering to the inner wall of the dispersion barrel 3.
