Textile machinery driving roller with parts convenient to replace

The utility model is applicable to the technical field of transmission rollers, and provides a textile machinery transmission roller convenient to replace parts, which comprises a fixed column, the inner side of the fixed column is fixedly connected with a limiting block, the inside of the fixed column is rotatably connected with a rotating block, the inside of the rotating block is rotatably connected with a rotating shaft, and the outer side of the rotating shaft is slidably connected with a rotating roller. One end of the rotating roller away from the rotating shaft is fixedly connected with a connecting structure. According to the textile machinery driving roller with the parts convenient to replace, when the rotating block rotates in the fixing column, the rotating block can guide the rotating roller to rotate around the upper end of the fixing column by means of sliding of the rotating roller and the outer side of the rotating shaft, so that the rotating roller is effectively lifted, and the rotating ro
