[0002] There are many printing methods. Among them, gravure printing is to cover the entire surface of the printing plate with ink, then remove the ink from the blank areas so that the ink remains only in the cells of the graphic part. Then, under greater pressure, the ink is transferred to the surface of the substrate to obtain the printed product. Gravure printing is a direct printing method.

[0003] During printing, a roller is required to pick up ink from the ink tank. To prevent ink from settling and forming nodules, the ink needs to be stirred. As the ink is consumed, the ink level in the ink tank continues to drop. However, as the level continues to drop, ink will adhere to the inner wall of the ink tank, causing ink drying loss.

During the stirring process, the stirring component 2 can scrape the ink on the inner wall of the shell 1, so that the ink on the inner wall of the shell 1 that is higher than the ink liquid level falls off, avoiding the ink adhering to the side wall of the shell 1 and causing the ink to dry out and be lost in the shade.

[0023] like Figure 3 and 4 As shown, the stirring assembly 2 includes a first rotating shaft 21, which is rotatably connected to the inside of the shell 1, and the side wall of the first rotating shaft 21 is fixedly connected with equidistantly distributed inclined plates 22, and the side wall of the inclined plate 22 is in contact with the inner wall of the shell 1. The surface of the inclined plate 22 is provided with evenly distributed through holes 25, and the side wall of the first rotating shaft 21 is symmetrically fixed with a circular plate 23, and one end of the circular plate 23 is fixedly connected with a first scraper 24, and one end of the first scraper 24 is in contact with one end of the inner wall of the shell 1.

[0024] According to the above structure, when in use, the first rotating shaft 21 drives the inclined plate 22 and the circular plate 23 to rotate. After the inclined plate 22 rotates, it can not only stir the ink on the inner wall of the shell 1, but also the side wall of the inclined plate 22 can scrape the ink on the inner wall of the shell 1 to prevent the ink from adhering to the inner wall of the shell 1. After the circular plate 23 rotates, the first scraper 24 at the end of the circular plate 23 can scrape the ink on the end of the inner wall of the shell 1 to reduce the loss of ink.

[0025] like Figure 3 and 4 As shown, a first motor 26 is fixedly connected to one end of the outer wall of the shell 1, and the first motor 26 is fixedly connected to one end of one of the first rotating shafts 21. The transmission assembly 3 includes two pulleys 31 respectively fixedly connected to one end of the two first rotating shafts 21, and a belt 32 is provided between the two pulleys 31.

[0029] The working principle of the utility model is as follows: when in use, the gravure roller 51 is driven to rotate by the second motor 52, and the second scraping strips 54 at both ends of the gravure roller 51 scrape the ink on both ends of the inner wall of the shell 1, and the gravure roller 51 picks up the ink inside the shell 1 for printing, and the first rotating shaft 21 drives the inclined plate 22 and the circular plate 23 to rotate. After the inclined plate 22 rotates, it can not only stir the ink on the inner wall of the shell 1, but also the side wall of the inclined plate 22 scrapes the ink on the inner wall of the shell 1 to prevent the inner wall of the shell 1 from adhering to the ink. After the circular plate 23 rotates, the first scraping strip 24 at the end of the circular plate 23 can scrape the ink on the end of the inner wall of the shell 1 to reduce the loss of ink. When working, the first rotating shaft 21 connected to it is driven to rotate by the first motor 26, and the other first rotating shaft 21 is driven to rotate through the transmission of the two pulleys 31 and the belt 32, so that the two first rotating shafts 21 rotate synchronously.
