Efficient leather manufacturing equipment achieving segmented wrinkle removal

Abstract

The invention discloses efficient leather manufacturing equipment achieving segmented wrinkle removal. The efficient leather manufacturing equipment comprises a heating roller, an impression roller, a humidification box, a steam nozzle communicated with an ultrasonic water atomization generator, a steam insulation plate and a barrier ring. The steam insulation plate is in an arc shap, and is arranged in the humidification box, humidification space is defined by the steam insulation plate, the humidification box and cloth, the two ends of the steam insulation plate are far away from the mounting face of the steam nozzle of the humidification box, and the center of the steam insulation plate is near to the mounting face of the steam nozzle of the humidification box. When the cloth penetrates through the humidification space, the two ends of the cloth are in contact with atomization steam for a long time. The barrier ring is composed of a plurality of circumferential bars identical in length and at least two axial bars, the barrier ring is arranged by being closely attached to the inner wall of a roller ring of the heating roller, the center intervals of the adjacent circumferential bars are the same, the widths of the circumferential bars are gradually reduced from the center of the roller ring to the two ends of the roller ring, the temperature of high-temperature oil is reduced when the high-temperature oil is conducted to the roller ring from the barrier ring, the temperature of the positions close to the two ends of the roller ring is high, and the temperature gradually changes. The efficient leather manufacturing equipment has the advantages of saving heat energy and water, achieving high-temperature high-humidity high-pressure setting and being good in precise control effect.

Description

technical field [0001] The invention relates to a device for ironing crepe cloth during synthetic leather processing. Background technique [0002] In the process of synthetic leather processing, 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 wrinkling and uneven, there is a pressure on the cloth before coating. , In the process of heating and wrinkle removal, because the wrinkled cloth has a certain elasticity, when the pressure and temperature are removed, it will return to a wrinkled state. The humidification process is added before pressing and heating to remove wrinkles through high temperature, high humidity and high pressure, and the effect of wrinkle removal is significantly improved, but things have two sides. When the cloth is transported from the cloth factory to the synthetic leather factory, the two ends of the cloth in the width dir...

Problems solved by technology

[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
