Heavy pressure mangle with high mangle expression

The utility model relates to a heavy-duty mangle of high liquid-mangling rates, which is mainly used for mangling liquid before drying fabrics in the continuous printing and dyeing product line. The heavy-duty mangle comprises a framework (1), an upper roller (2) and a lower roller (3); the upper roller (2) and the lower roller (3) are vertically arranged on the framework (1) from top to bottom, the upper roller (2) and the lower roller (3) are both steel rubber composite rollers and comprise inner-circle steel rollers, outer-circle rubber rollers and a plurality of small oil cylinders, and the oil cylinders are embedded in the cavities between the inner-circle steel rollers and the outer-circle rubber rollers of the upper roller (2) and the lower roller (3). By the two high-hardness and high-elastic rubber rollers, the mangle minimizes the liquid volume of the fabric as far as possible so as to improve the drying efficiency or to effectively control the use of chemicals needed by the fabric, and then achieve
