The invention provides a cold pad-batch dyeing machine for knitted fabric.The cold pad-batch dyeing machine is characterized by comprising an open-width cloth inlet unit, a dust suction unit, a cooling unit, an edge unfolding unit, a dyeing unit, a cloth outlet unit and a moving and rolling unit.The open-width cloth inlet unit is arranged on the upper side of the dust suction unit and the cooling unit.The dust suction unit is arranged on the left side of the cooling unit.The cooling unit, the edge unfolding unit, the dyeing unit, the cloth outlet unit and the moving and rolling unit are sequentially arranged from left to right.An open-width processing mode is adopted, the structure is compact, the knitted fabric is effectively prevented from being wrinkled or crimped in the processing process, tension changes are small in the deformation process of the knitted fabric, and the effect of even dyeing can be achieved.According to the cold pad-batch dyeing machine, low-tension control can be effectively carried out over the knitted fabric in the whole drying link; all the technological processes are short, the utilization rate of dyes can be greatly improved, water saving and consumption reducing are achieved, production cost is reduced, and environmental pollution is small.
