Nail surface rust removal device for nail manufacturing

The invention relates to the technical field of rust removal, in particular to a nail surface rust removal device for nail manufacturing, which comprises a treatment box for containing rust removal acid liquor, a pH value sensor, a first liquid level sensor, an acid injection mechanism and a controller, the pH value sensor is arranged in the treatment box and used for detecting the pH value of the rust removal acid liquid, the first liquid level sensor is used for detecting the remaining amount of the rust removal acid liquid in the treatment box, and the acid filling mechanism is used for adding the rust removal acid liquid into the treatment box; when the concentration or residual amount of the acid liquor in the treatment box is lower than a set threshold value, automatic adding can be conducted in time, the stability and consistency of rust removal operation are ensured, incomplete rust removal or rust residue caused by too low concentration of the acid liquor is avoided, and the nail production quality i
