Energy-saving tanning device with segmented wrinkle removal

Abstract

The present invention discloses an energy-saving tanning device with segmented wrinkle removal. The device comprises a heating roller, an impression roller, a spray pipe, and a fence ring, wherein two end heads of the spray pipe are sealed the spray pipe is disposed above cloth, an inlet is arranged in the center of the spray pipe and is communicated with an ultrasonic wave water atomization generator, a plurality of spray holes are formed in a pipe wall of the spray pipe, center-to-center distance of the spray holes is the same, areas of the spray holes close to two ends of the spray pipe is larger than that of the spray holes adjacent to the center of the spray pipe and gradually change, and when the cloth passes below the spray holes, and humidity of the two ends of the cloth contacting atomizd steam is high; the fencing ring is composed of a plurality of circumferential strips of the same length and at least two axial strips, the fencing ring is installed close to an inner wall of a roller ring of the heating roller, center-to-center distance between adjacent circumferential strips is the same, the width of the circumferential strips reduces gradually from the center of the roller ring to two ends of the roller ring, and the temperature of a high temperature oil lowers after the oil is conducted to the roller ring, reaches the highest at positions close to the two ends of the roller ring, and changes gradually. The benefical effects of the tanning 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...

[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
