Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for lithographic offset printing water-based ink. Background Art

[0002] Offset printing is a type of lithography. Simply put, offset printing is a printing method that uses rubber to transfer the image on the printing plate to the substrate. It is also because of the existence of the rubber blanket that this printing method got its name. When printing, water-based ink needs to be applied to the rubber, and then the rubber is pressed on the object to be printed to complete the printing.

[0003] When preparing water-based ink, it is necessary to stir and mix a variety of materials to achieve better ink performance. The water-based ink is usually stirred by a common stirring device. However, after the existing stirring device stirs and discharges the material, residual ink will remain at the bottom of the stirring device and cannot flow to the discharge port to complete the discharge. Over time, the ink will dry up and adhere to the bottom of the stirring device, thereby affecting subsequent preparation. To this end, we propose a lithographic offset printing water-based ink stirring device to solve the above problem. Utility Model Content

Figure 2 , the stirring blade 7 is provided with multiple groups, so that a filter plate 10 is provided at the bottom end of the stirring blade 7, and the stirring blade 7 is fixedly connected to the filter plate 10, so that the stirring blade 7 can drive the filter plate 10 to rotate together, and the outer wall of the filter plate 10 at the bottom end of the lowest stirring blade 7 is fixedly connected to the inner wall of the stirring barrel 1, so that the group of filter plates 10 is sleeved on the outside of the rotating rod 6, and the bottom end of the group of stirring blades 7 and the top end of the group of filter plates 10 are fitted with each other, and then a connecting pipe 8 is provided at the bottom end of the feed port 3, and the connecting pipe 8 is inclined, so that a receiving platform 9 is provided on the outside of the rotating rod 6, and the receiving platform 9 is located below the openings of the two groups of connecting pipes 8.

[0031] Working principle: When the utility model is in use, the raw materials enter the interior of the mixing barrel 1 through the feed port 3, and then are aggregated through the connecting pipe 8, and then fall to the top of the receiving platform 9 for preliminary mixing.
