This utility model discloses a textile finishing and dyeing machine, relating to the technical field of textile processing equipment. It aims to solve the technical problem that current textile finishing and dyeing machines are inconvenient for removing excess dye from fabrics that have passed through the dyeing vat. The machine includes a main body. Through its designed cleaning structure, this utility model adjusts the relative movement of two sets of clamps inside the cavity during fabric dyeing. The clamps apply pressure to the fabric. When the two sets of fabric rollers in the main body of the dyeing machine repeatedly unload and reload the fabric, the fabric passing through the dyeing vat first passes through the cavity. Then, the two sets of clamps in the cavity squeeze out excess dye from the fabric. The fabric rollers in the main body then unload and reload the fabric with the squeezed-out excess dye, thus avoiding a large amount of excess dye remaining on the fabric and preventing dye splashing during the unloading and reloading process.
