Water-saving and power-saving leather making equipment realizing segmented crease removal

Abstract

The invention discloses water-saving and power-saving leather making equipment realizing segmented crease removal. The water-saving and power-saving leather making equipment comprises a heating roller, a pressurizing roller, a spray pipe and a fence ring, wherein two ends of the spray pipe are closed, the spray nozzle is located above cloth, an inlet is formed in the center and communicated with an ultrasonic water-atomizing generator, a plurality of spray holes are formed in the wall of the spray pipe and arranged as follows: space of the spray holes close to the center of the spray pipe is maximum, space of the spray holes close to two ends of the spray pipe is minimum, the space changes gradually, when the cloth passes through the part below the spray holes, the humidity of the two ends, contacted with atomized vapor, of the cloth is high, the humidity of center, contacted with the atomized vapor, of the cloth is low, and the humidity changes gradually; the fence ring comprises multiple circumferential strips with the same length and at least two axial strips and is mounted tightly to the inner wall of a roller ring of the heating roller, the adjacent circumferential strips have the same center space, the width of each circumferential strip is gradually reduced from the center to two ends of the roller ring, the temperature, transmitted from the fence ring to the roller ring, of high-temperature oil is reduced, the temperature of the position close to the two ends of the roller ring is the highest, and the temperature changes gradually. The water-saving and power-saving leather making equipment has the benefits of water saving, power saving, high-temperature, high-humidity and high-pressure setting and good accurate control effect.

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
