The invention discloses a double-channel soldering iron adjusting tool of a high-speed cigarette making machine. The double-channel soldering iron adjusting tool comprises a base, a soldering iron supporting plate, a supporting seat and a soldering iron body, the base is fixed on a support surface, a first reference surface is formed on the top surface of the base, an accommodating cavity for accommodating a test mandrel is formed in the base, and a through groove is concavely formed in the first reference surface; the middle of the soldering iron supporting plate is fixed to the supporting face through the supporting seat, a second reference surface is formed on the top face of the soldering iron supporting plate, and a first adjusting assembly is arranged at the first end of the soldering iron supporting plate. The soldering iron body is fixed to the second end of the soldering iron supporting plate in a liftable mode, and a second adjusting assembly is arranged on the soldering ironbody. And a third adjusting assembly is arranged on the supporting seat. Compared with the prior art, by arranging the first adjusting assembly, the second adjusting assembly and the third adjustingassembly, the technical problem of rapid adjustment of the working position of the double-way soldering iron of the cigarette making machine can be rapidly solved.
