Fast ironing equipment for tanning

Abstract

The invention discloses a quick ironing device for leather making, which comprises: a heating roller; a pressure roller; a nozzle connected to an ultrasonic water atomization generator, located above the cloth, and several nozzles are arranged on the wall of the nozzle. Nozzle holes, the distance between the centers of the several nozzle holes is the same, the area of ​​the nozzle holes near the two ends of the nozzle is larger than the area of ​​the nozzle holes near the center of the nozzle and changes gradually, when the cloth passes under the nozzle holes, the two ends of the cloth contact the atomized vapor The humidity is high, and when it is close to the center of the cloth, the humidity in contact with the atomized vapor is low; the heating roller includes: a fence ring, which is composed of a plurality of circumferential strips with the same width and length and at least two axial strips, the fence circle It is installed close to the inner wall of the roller ring, wherein the distance between the circumferential strips near the two ends of the roller ring is greater than the distance between the circumferential strips near the center of the roller ring, and the distance changes gradually. The fence ring blocks the heat absorption of the roller ring. The beneficial effects of the invention are: saving heat and water, high temperature, high humidity and high pressure setting, and good effect of precise control.

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
