The ironing device comprises a heating roller, an impression roller assorted with the heating roller, and a spray pipe communicated with an ultrasonic wave water atomization generator, wherein a plurality of spray holes are formed in a pipe wall of the spray pipe and are in the following arrangement, gaps close to the center of the spray pipe are the largest while gaps close to two ends of the spray pipe are the smallest, the gaps change gradually, and when cloth penetrates below the spray holes, humidity of two ends of the cloth contacting atomized steam is high while that of the center of the cloth contacting the atomizd steam is low, and the humidity changes gradually; the heating roller comprises a fence ring composed of a plurality of circumferential strips of the same width and length and at least two axial strips, the fencing ring is installed close to an inner wall of a roller ring, distance between circumferential strips close to the two ends of the roller ing is larger than that between circumferential strips close to the center of the roller ring, the distance changes gradually, and the fence ring prevents the roller ring from absorbing heat. The benefical effects of the ironing device are energy conservation, high temperature, high humidity and high pressure setting, and excellent precision control effects.

The invention discloses quick ironing equipment for tanning. The quick ironing equipment for tanning comprises a heating roller and an impression roller. A spray pipe communicated with an ultrasonic water atomizing generator is located above cloth. The pipe wall of the spray pipe is provided with a plurality of spray holes, the center intervals of the spray holes are the same, the areas of the spray holes close to the two ends of the spray pipe are larger than the areas of the spray holes close to the center of the spray pipe and gradually change. When the cloth penetrates through the position below the spray holes, the humidity of the two ends of the cloth in contact with atomizing steam is high, and when the center of the cloth is approached, the humidity of the cloth in contact with the atomizing steam is low. The heating roller comprises a fence ring, the fence ring is composed of a plurality of peripheral strips which are the same in both width and length and two or more axial strips, the fence ring is tightly attached to the inner wall of a roller ring, the interval distances of the peripheral strips close to the two ends of the roller ring are larger than the interval distances of the peripheral strips close to the center of the roller ring, the interval distances gradually change, and the fence ring prevents the roller ring from absorbing heat. The quick ironing equipment for tanning has the advantages that heat energy and water are saved, high-temperature high-humidity high-pressure shaping is achieved, and the accurate control effect is good.
