Efficient ironing equipment based on synthetic leather processing

Abstract

The invention discloses efficient ironing equipment based on synthetic leather processing. The efficient ironing equipment comprises a heating roller, a pressure applying roller, a humidification box, steam nozzles communicated with an ultrasonic-wave water atomization generator as well as steam isolating plates, wherein the arc-shaped steam isolating plates are mounted in the humidification box; humidification space defined by the steam isolating plates, the humidification box and fabric can meet the following requirements: when the fabric penetrates through the humidification space, the time when two ends of the fabric are contacted with atomized steam is long, and the time when positions, close to the center of the fabric, of the fabric is contacted with the atomized steam is short; the heating roller comprises a round heat-collection barrel which comprises a hollow body and a plurality of heat-collection pieces arranged on the inner wall of the hollow body, the outer surface of the hollow body is tightly attached to the inner wall of a roller ring, each heat-collection piece adopts a structure of symmetrical double triangles, apexes of the double triangles are close to the center of the hollow body, the round heat-collection barrel can absorb heat from high-temperature oil, the temperature of positions close to two ends of the roller ring is high, and the temperature changes gradually. The efficient ironing equipment based on synthetic leather processing has the benefits of heat energy saving, water saving, high-temperature, high-humidity and high-pressure setting and good accuracy control effect.

Description

technical field [0001] The invention relates to an equipment for processing synthetic leather and ironing corrugated cloth. 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
