Description

Technical Field

[0001] The utility model relates to the technical field of etching liquid production, in particular to a stirring device for etching liquid production. Background Art

[0002] The main purpose of stirring the etching solution is to ensure that the chemical components in the etching solution are evenly distributed to maintain the stability and consistency of the etching rate. In addition, stirring also helps prevent the accumulation of precipitates generated during the etching process on the plate surface and in the solution, which may affect the etching effect. The stirring device for etching solution production in the prior art is realized by setting a stirring rod. When the stirring rod stirs and mixes the etching solution, the stirring rod rotates at the same height, which makes it difficult to quickly drive the etching solution in the mixing barrel to flow and mix up and down. In addition, there is a tendency for precipitation to occur on the bottom side of the mixing box, and the newly added liquid on the upper side of the mixing box is difficult to quickly integrate into the mixing box, resulting in a relatively low stirring and mixing efficiency of the etching solution. Therefore, this application proposes a stirring device for etching solution production to solve the above problems. Utility Model Content

[0011] (3) Beneficial effects

[0012] The beneficial effects of the present invention are:

[0013] The stirring device for producing etching liquid has two lifting cylinders arranged on the driving shaft.
