This utility model discloses a smoothing structure for a heat-setting device used in the production of soft, lightweight silk jacquard fabrics. It aims to solve the problem that, since most jacquard fabrics have raised patterns, using rigid rollers to squeeze the fabric can damage the raised patterns, thus affecting product quality. This utility model uses several drive rods mounted on an installation tube, with push rods and push plates slidably mounted on these drive rods. Springs are also installed on the push rods, allowing the push plates to have a certain elasticity when squeezing the fabric, preventing excessive pressure on the raised patterns and reducing the possibility of damage. Furthermore, during the rotation of the installation tube, the installation rods move laterally under the action of the pushing mechanism, further applying tension to the fabric in the lateral direction and further improving the smoothing effect.
