Door loop line welding cleaning system

The utility model relates to a door loop line welding cleaning system which comprises a conveying mechanism and a welding base plate, and the welding base plate can move on the conveying mechanism in the Y-axis direction. A sweeping mechanism used for sweeping the welding base plate is arranged over the conveying mechanism, and a jacking mechanism used for jacking the welding base plate is arranged under the conveying mechanism. The conveying mechanism, the cleaning mechanism and the jacking mechanism are used in cooperation, the welding base plate can be cleaned, the risk of abnormal door ring machining caused by excessive welding slag accumulation of the welding base plate is reduced, the cleaning process is automatically operated, operation is easy, and use is convenient; after the conveying mechanism conveys the welding base plate to the cleaning station, the welding base plate is jacked through the jacking mechanism, and in the process that the cleaning mechanism cleans the welding base plate, the weldin
