the distance between the surfacing welding gun 24 and the upper surface of the wear-resistant roller 4 is adjusted through the adjusting seat 23, the surfacing welding gun 24 is adjusted to one end of the threaded rod 22, the first motor 28 is started, the surfacing welding gun 24 is started simultaneously, the output end of the first motor 28 starts to rotate, the threaded rod 22 is synchronously driven to synchronously rotate in the rotation process of the output end of the first motor 28, the adjusting seat 23 slides to the other end along one end of the installation guide shell 21, the surfacing welding gun 24 is synchronously driven by the adjusting seat 23 at the moment, surfacing operation on the surface of the wear-resistant roller 4 is realized through the surfacing welding gun 24, the adjusting seat 23 reciprocates along the outer wall of the threaded rod 22 by changing the rotation direction of the first motor 28 and simultaneously driving the threaded rod 22 to reversely rotate, the surfacing welding efficiency is improved, the shielding plates 25 at the two ends of the installation guide shell 21 can block arc light generated in surfacing, and strong arc light is prevented from stimulating eyes of workers, the protecting function is achieved for workers, meanwhile, a large amount of smoke dust can be generated by the surfacing regulations, the shielding plates 25 at the two ends can block the smoke dust, the smoke dust is reduced from flying into the air, the body health of the workers is affected, when the wear-resisting roller 4 is placed in the placing groove 11, the shielding plate 25 at the front end can be lifted, meanwhile, the tensioning spring 27 is stretched, after the wear-resisting roller 4 is placed in the placing groove 11, the tensioning spring 27 pulls the shielding plate 25 to return to the original position, the shielding plate 25 can block the wear-resisting roller 4, and the shielding plate 25 can prevent the wear-resisting roller 4 from rolling out of the placing groove 11;

when other parts of the outer wall of the wear-resistant roller 4 are subjected to surfacing, the wear-resistant roller 4 needs to be rotated, the position which is not subjected to surfacing is rotated to the position under the surfacing welding gun 24, the second motor 32 is started, the output end of the second motor 32 drives the first transmission column to rotate, the first transmission column drives the transmission support column 34 to synchronously rotate through the transmission belt 33 in the rotating process, the fixed shaft 41 is arranged between the first transmission column and the transmission support column 34, and in the rotating process of the first transmission column and the transmission support column 34, the fixed shaft 41 is simultaneously driven to synchronously rotate, the fixed shaft 41 can be ensured to be more slowly and stably rotated through the arc-shaped friction plate 51, meanwhile, the fixed shaft 41 can be prevented from rolling out from the position between the first transmission column and the transmission support column 34, and the wear-resistant roller 4 is stably and synchronously driven to rotate through the fixed shaft 41;

in the rotating process of the wear-resistant roller 4, the surface of the wear-resistant roller 4 after overlaying is cooled by the cooling fan 63 arranged on the inner wall of the cooling plate 61, meanwhile, welding slag on the surface of the wear-resistant roller 4 can be blown to the surface of the guide scraper 66 by the cooling fan 63, the welding slag slides down through the surface of the guide scraper 66 and enters the welding slag collecting box 12 for centralized collection, when the wear-resistant roller 4 rotates, the upper surface of the guide scraper 66 rubs with the outer wall of the wear-resistant roller 4, further, the welding slag on the outer wall of the wear-resistant roller 4 after overlaying is cleaned, the jacking springs 7 push the jacking plates 71, the jacking columns 72 are supported by the two jacking plates 71, the guide scraper 66 is pushed by the jacking columns 72, the guiding scraper 66 and the outer wall of the wear-resistant roller 4 are kept in a butting state all the time, and the cleaning effect of the welding slag attached to the outer wall of the wear-resistant roller 4 by the guiding scraper 66 is improved.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention.
