Energy-saving leather making equipment capable of realizing segmented ironing

Abstract

The invention discloses energy-saving leather making equipment capable of realizing segmented ironing. The equipment comprises a heating roller, a pressure applying roller, a humidification box, steam nozzles communicated with an ultrasonic water atomization generator, a steam isolating plate and an electric heater, wherein the steam isolating plate is arc-shaped and mounted in the humidification box, a humidification space is defined by the steam isolating plate, the humidification box and fabric, distances between two ends of the steam isolating plate and the steam nozzle mounting surface of the humidification box are long, and the distance between the center of the steam isolating plate and the steam nozzle mounting surface of the humidification box is short; the electric heater comprises an electric heating wire, an insulating frame and a heat collecting cover, is mounted on a rack and can heat a roller ring, the electric heating wire winds around the insulating frame, parts, close to two ends of the roller ring, of the electric heating wire wind densely, the part, close to the center of the roller ring, of the electric heating wire winds sparsely, the density changes gradually, the two ends of the roller ring obtain more heat and have higher temperatures, the center of the roller ring obtains less heat and has the lower temperature, and the temperatures change gradually. The equipment has the benefits as follows: the equipment is reasonable in structure, low in cost, good in accurate control effect and capable of saving heat energy, water and electricity and realizing high-temperature, high-humidity and high-pressure setting.

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
