The invention discloses a water-based printing ink stirring device and a printing ink preparation technology. The water-based printing ink stirring device comprises a stirring barrel, wherein a base is connected with the bottom of the stirring barrel; one end of each fourth straight bar is connected with the top of the base; the other end of each fourth straight bar is hinged with one end of eachof two second straight bars; the other end of each second straight bar is hinged with one end of each sixth straight bar; the other ends of the two sixth straight bars are hinged with one end of the same first straight bar; the other ends of the first straight bars are connected with a motor through fifth straight bars; a hollow shaft is connected with an output end of the motor. The water-based printing ink stirring device is simple in structure, raw materials are subjected to triple stirring at one time by the aid of the stirring device, so that the raw materials are sufficiently mixed, andproduction efficiency of the raw materials is improved; meanwhile, various raw materials and auxiliaries are added in proportion, therefore, the produced printing ink has better deposition-preventingeffect, and color of the printing ink is less affected in the normal using process.
