Knitted fabric mercerizing device

The utility model discloses a knitted fabric mercerizing device which comprises a dyeing box, a placing connecting plate is arranged at the left end of the dyeing box, an extrusion roller is arranged at the inner side of a fixing frame at the left end, and rotating clamping blocks are arranged at the front end and the rear end of the dyeing box. A sliding groove block is arranged at the right end of the guide roller, a connecting spring is arranged in a sliding groove, and an extrusion clamping block is arranged on the outer side of the connecting spring. Through extrusion clamping blocks with connecting springs, the phenomenon that when an extrusion plate is thin, the extrusion plate easily shakes to affect tension stretching of the extrusion plate on the knitted fabric, and then the mercerizing effect of the knitted fabric is affected can be effectively avoided; and by rotating a clamping block and adding a convex block on the placing connecting plate, the placing connecting plate can be more conveniently a
