Water-saving and electricity-saving ironing equipment for tanning

Abstract

The present invention discloses a water-saving and power-saving ironing device for tanning. 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.

Description

technical field [0001] The invention relates to a device for ironing corrugated cloth during synthetic leather processing. Background technique [0002] During the processing of synthetic leather, the cloth is sent to the coating machine, and the heated leather slurry is coated on the cloth to form synthetic leather. In the prior art, in order to prevent the cloth from being wrinkled and uneven, there is a process of pressing the cloth before coating 1. In the process of heating and removing wrinkles, since the wrinkled cloth has certain elasticity, when the pressure and temperature are removed, it will return to the wrinkled state to some extent. In order to further improve the wrinkle removal effect, the humidity can be increased, that is, after adding Increase the humidification process before pressing and heating, and remove wrinkles through high temperature, high humidity, and high pressure, and the wrinkle removal effect will be significantly improved. However, there a...

[0002] During the processing of synthetic leather, the cloth is sent to the coating machine, and the heated leather slurry is coated on the cloth to form synthetic leather. In the prior art, in order to prevent the cloth from being wrinkled and uneven, there is a process of pressing the cloth before coating 1. In the process of heating and removing wrinkles, since the wrinkled cloth has certain elasticity, when the pressure and temperature are removed, it will return to the wrinkled state to some extent. In order to further improve the wrinkle removal effect, the humidity can be increased, that is, after adding Increase the humidification process before pressing and heating, and remove wrinkles through high temperature, high humidity, and high pressure, and the wrinkle removal effect will be significantly improved. However, there are two sides to things. High humidity will evaporate after high temperature, and steam will take away a lot of heat, thus increasing energy. When the cloth is transported from the cloth factory to the synthetic leather factory, the two ends of the cloth in the width direction are most likely to wrinkle due to the influence of packaging and transportation, while the center of the cloth is not easy to wrinkle. In addition, the cloth passes through the transmission roller during the synthetic leather coating process. At the same time, the center of the cloth is easy to tighten, and the two ends of the width of the cloth are relatively loose. Finally, because the two ends of the heating roller are easy to dissipate heat through the end surface of the roller, the roller shaft and the frame, the temperature at both ends of the heating roller ring is relatively low. According to Based on the principle of thermal expansion and contraction, the diameter of the two ends of the roller ring affected by the low temperature is small, and there is a gap between the two ends of the heating roller and the pressure roller, which cannot apply uniform pressure to the cloth. Therefore, the two ends of the cloth are not easy to flatten. The probability of quality problems at both ends of synthetic leather after coating is high
