As an optimized proposal of the utility model, the frame is positioned at one end of the feeding side of the hot rolling embossing machine and is provided with a cloth guide roller.

As an optimized scheme of the utility model, it has the circulation conduction oil to lead to in the first hot roll, it has the circulation conduction oil to lead to in the second hot roll.

As a preferred scheme of the utility model, first hot roll by first motor drive and can pivoted install in the frame, the second hot roll by second motor drive and can pivoted install in the frame.

As an optimized scheme of the utility model, the fine opener with be provided with metal detector between the automatic cotton feeder.

As an optimized proposal of the utility model, the carding machine is a double-cylinder carding machine.

As a preferable aspect of the present invention, the cross section of the notch is circular, oval, quadrilateral, triangular, or trapezoidal.

The beneficial effects of the utility model are that, the utility model discloses a set up the hot rolling coining mill between carding machine and oven, and then make the non-woven fabrics dry and stereotype again after the knurling is accomplished, thereby can extrude closely knit decorative pattern, guarantee disposable moisture absorption articles for use's water conservancy diversion performance and moisture absorption performance, in addition, the first hot roll of hot rolling coining mill is the smooth roll, the surface of second hot roll is provided with a plurality of notch, first hot roll, the second hot roll contacts, can further improve the knurling effect, the decorative pattern of assurance extrusion is tight real, moreover, the steam generator is simple in structure, and easy realization.
