Description

Technical Field

[0001] The utility model relates to the technical field of uniform inkjet equipment, in particular to a printing material uniform jetting device. Background Art

[0002] In order to ensure the printing quality of the printed part, it is often necessary to uniformly spray the ink through the nozzle, and then a uniform inkjet device is needed. The utility model patent with patent application number CN202220551612.X discloses a uniform inkjet device for a printer, which uses an ink storage box to store ink, and cooperates with a liquid pump and a connecting pipe to extract ink, uses a processing box to store the ink extracted by the liquid pump, and uses a filter plate to filter the introduced ink, so as to facilitate filtering of particulate impurities or breaking of foam generated during extraction, and fully avoid affecting the uniform inkjet of the nozzle. The sealing plate is used to facilitate quick removal of the filter plate for cleaning, which is convenient for users to operate and use. According to the technical solution disclosed by the utility model, when the existing uniform inkjet device is used, on the one hand, when the ink is stirred evenly, the single rotation of the stirring mechanism is not conducive to uniformly dispersing the sediment into the ink again, which is not conducive to ensuring the uniform ink jetting work. On the other hand, after the printing work is completed, the ink retained in the nozzle is easy to cause clogging of the nozzle due to air drying, and personnel are often required to clean the nozzle, which is inconvenient to use.

[0003] Therefore, how to design a device for uniformly ejecting printing materials has become our current problem to be solved. Utility Model Content
