Compression roller of engraving machine

The utility model provides a carving machine compression roller which comprises a main compression roller, and a protection ring is movably embedded in the outer wall of the main compression roller. Telescopic rods are mounted at the left and right ends of the main compression roller through bolts; a socketed pipe is connected between the telescopic rods in a sleeving manner, and the joint is fixed through a bolt; a lifting seat is mounted on the outer wall of the socketed pipe through bolts; a supporting stand column frame structure is supported in the lifting base. A synchronous adjusting operation frame structure is supported at the upper end of the supporting stand column frame structure. Through the arrangement of the synchronous adjustment operation frame structure, the vertical threaded rods at different positions are synchronously driven to rotate so as to be synchronously matched with the lifting seat and the main compression roller for lifting adjustment. 本实用新型提供一种雕刻机压辊，包括主压辊，主压辊外壁上活动镶嵌有防护环；主压辊左右两端均
