Scraping and recycling device for outer weld bead of pipe

The utility model provides a scraping and recycling device for an outer welding bead of a pipe. The scraping and recycling device comprises a workbench, a scraper mechanism and a winding mechanism, the scraper mechanism comprises a first cutter module, a first outer scraper arranged on the first cutter module, a second cutter module and a second outer scraper arranged on the second cutter module; the winding mechanism is arranged above the workbench and comprises a guiding module and a rewinding module. And the pipe is continuously input into the scraper mechanism under the traction of an external force, so that the stripped welding wire is continuous and is further obtained by the guide module and the rewinding module of the winding mechanism, and the end part of the welding wire is guided to the rewinding module along the guide module, so that the welding wire is automatically stripped. The device is simple in structure, better in safety and operability, and capable of remarkably improving the machining eff
