Description

Roller sleeve overlaying device Technical Field The utility model belongs to the technical field of overlaying, and relates to an overlaying device, in particular to a roller sleeve overlaying device. Background The surfacing is an economical and rapid process method for modifying the surface of materials, and is increasingly widely applied to the manufacturing and repairing of parts in various industrial departments. In order to most effectively perform the function of the build-up layer, it is desirable to employ a build-up method that has less dilution of the base material, higher deposition rate, and excellent build-up layer properties, i.e., a build-up technique that is excellent, efficient, and low in dilution. The surfacing welding device with the publication number of CN217193485U comprises a welding gun, a first powder feeder and a second powder feeder, wherein the first powder feeder and the second powder feeder are arranged at intervals with the welding gun, the first powder feeder and the second powder feeder are arranged at intervals, the first powder feeder or the second powder feeder can move along the direction of a plumb line or along the horizontal direction along with the welding gun at the same time and abut against or are far away from a workpiece, the first powder feeder and the second powder feeder are respectively communicated with the welding gun, and the first powder feeder and the second powder feeder are respectively used for conveying different surfacing welding raw materials to the welding gun. According to the surfacing device, after powder is sprayed on the surface of the workpiece, the surface of the workpiece is further processed through the welding gun, but the situation that the powder drifts at the edge of the chuck to cause waste exists in the welding gun processing and the powder spraying process, so that the surfacing cost is increased. Disclosure of utility model The utility model provides a roller sleeve overlaying device which can collect powder scattered on the edge of a chuck, so that waste is reduced, and cost is lowered. The utility model solves the technical problems by adopting the technical scheme that the roller sleeve overlaying device comprises a chuck, wherein a baffle is sleeved at the edge of the chuck, a plurality of mounting grooves are formed in the bottom surface of the baffle, a fan is fixedly connected in each mounting groove, a collecting ring is detachably connected below the fan, a groove communicated with the mounting grooves is formed in the collecting ring, and when the fan is opened before powder is sprayed, the powder scattered on the edge of the chuck enters the groove through the fan. The baffle plate comprises an inclined plate and a flat plate integrally formed with the inclined plate, the fan and the collecting ring are arranged on the flat plate, and the diameter of the inclined plate gradually increases from one end close to the flat plate to one end far from the flat plate.
