[0002] Conductive silver paste is widely used in printed circuit boards, single-board ceramics, varistors and thermistors, piezoelectric ceramics, and silver electrodes for carbon film potentiometers. Conductive silver paste is usually mixed by stirring. During the production process, some raw materials such as silver powder and adhesive need to be poured into the mixing device in a certain proportion for mixing.

[0003] A Chinese patent discloses a low-temperature curing environmentally friendly conductive silver paste preparation device, the publication number is CN118155933A, including a preparation barrel and a barrel cover, the top of the barrel cover is evenly fixed with multiple support rods in the circumferential direction, two fixed plates are fixedly installed between the multiple support rods, and multiple storage barrels are equidistantly installed in the circumferential direction between the two fixed plates, and the bottom ends of the multiple storage barrels are fixedly installed with fixed tubes. The present invention drives the driving gear to rotate while the stirring shaft rotates, so that the driving gear drives the multiple driven gears meshing with it to rotate, so that the driven gear can drive the multiple storage barrels to rotate, so that the stirring blades fixedly installed inside the storage barrel can pre-mix the raw materials separately, so as to avoid precipitation of the internal components of the raw materials and affect the preparation purity of the environmentally friendly conductive silver paste.
