Further, the device comprises a second pressure device 11, wherein the second pressure device 11 comprises a bottom roller and a press roller 10, the bottom roller is fixed on the frame 1, the press roller 10 is connected with the second pressure device 11, and the press roller 10 and the bottom roller are pressed against each other through the second pressure device 11.

Further, at least one ironing wheel is arranged in front of the first liquid carrying roller 2, and the ironing wheel is rotatably connected to the frame 1.

Further, the first liquid carrying roller 2 or/and the second liquid carrying roller 3 or/and the bottom roller, and the press roller 10 are liquid carrying rollers of a double-layer structure, the liquid carrying rollers of the double-layer structure comprise an outer layer, an inner layer and a shaft core, the outer layer is a thick-wall steel pipe, the inner layer is a thick-wall steel pipe or a round steel, the diameter of the cross section of the middle part of the inner layer is larger than that of the cross section of the two end parts, the outer wall of the middle part of the inner layer is connected with the inner wall of the middle part of the outer layer, and the two end parts of the outer layer and the two end parts of the inner layer are connected in an abutting mode through check rings or; the inner layer is connected with the core, the outer layer is connected with the shaft core in an abutting mode through a check ring arranged at the end portion of the outer layer, the surface of the outer layer is made of stainless steel or electroplated hard chromium steel or ceramic or is provided with an encapsulated surface, silica gel is preferentially used for encapsulating, a working area of the encapsulated surface is provided with concave portions or convex portions, and the concave portions or the convex portions form a pre-designed pattern on the surface of the outer layer.

The central axes of the first liquid-carrying roller 2, the second liquid-carrying roller 3 and/or the bottom roller and the press roller 10 are through axes, the middle part of the central axes in the width direction is connected with the inner circle of the roller blank of the liquid-carrying roller in a hot fit or welding manner, the length of the connection is between one fourth of the length of the roller surface of the liquid-carrying roller and the length of the roller surface in the width direction of the roller surface of the liquid-carrying roller, and the connection length is preferably one third of the length of the roller surface.

Further, one or more of a tension control device, a spreading device, a static elimination device and the like are arranged at the inlet guide wheel and/or the outlet guide wheel, and the spreading device is one or more of an arc spreading device, an aluminum sheet type spreading device, a spiral spreading device and the like;

furthermore, in order to prevent the cloth from being wrinkled, a cloth unfolding device is arranged in front of an inlet of the pressing device, and the unfolding device is an arc-shaped unfolding roller, a spiral unfolding roller, an aluminum sheet type unfolding roller or the like.

Furthermore, in order to adjust and control the running speed, a tension detection and control device is arranged at an outlet (or a subsequent station) of the rolling device, the tension detection and control device is a swing arm type tension controller or a pressure sensor, and the rotating speed of the rolling device is controlled by detecting the tension condition of the cloth surface.

As an extension of practical application, the padder in this embodiment can be used for not only performing micro-feeding hydraulic rolling on cloth, but also coating operation of functional coating, and only needs to change a dye solution into a functional coating solution, such as a softening agent, a stiffening resin, a mildew preventive, a color fixing agent, an alkaline agent, an oxidizing agent, and the like, and the production operation process is applied as in the foregoing example.

While the micro-feeding padder provided with the double-sided coating and rolling device of the present invention has been described in detail, those skilled in the art will appreciate that the embodiments and applications of the invention are not limited to the above description.
