Water-saving and power-saving wrinkle removal equipment for synthetic leather processing

Abstract

The invention discloses water-saving and power-saving wrinkle removal equipment for synthetic leather processing. The equipment comprises a heating roll and a pressurizing roll which are mutually matched, wherein the heating roll comprises an inner cylinder provided with a first insulating material on the outer surface and an electric heating wire winding the first insulating material on the inner cylinder, the electric heating wire close to two ends of the inner cylinder is wound densely, the electric heating wire close to the center of the inner cylinder is wound sparsely, the gradual density transition of the electric heating wire is realized, the inner cylinder is nested in the a roll ring, and space between the electric heating wire and the inner surface of the roll ring is filled with a second insulating material; when the electric heating wire heats, temperatures of two ends of the roll ring are the highest, and the central temperature of the roll ring is the lowest; a spray pipe is located above cloth and is communicated with an ultrasonic water atomization generator; a plurality of spraying holes are formed in the wall of the spray pipe, the center interval between every two of the spraying holes is identical, the area of each of spraying holes close to two ends of the spray pipe is larger than that of each of spraying holes close the center of the spray pipe, and the areas of the spraying holes gradually change from two ends to the center. The equipment has the benefits as follows: the equipment is power-saving, water-saving, can realize setting at high temperature and under conditions of high humidity and high pressure and has a good accurate control effect.

Description

technical field [0001] The invention relates to a wrinkle-removing device for processing synthetic leather.

[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 direction of the cloth are relatively loose. Finally, because the two ends of the heating roller ring are easy to dissipate heat through the roller end face, roller shaft and frame, the temperature at the two ends of the heating roller ring is relatively low. , according to 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 press the cloth evenly. Therefore, the two ends of the cloth are not easy to press Flat, there is a high probability of quality problems at both ends of the synthetic leather after coating
