Efficient wrinkle removing equipment for synthetic leather processing

Abstract

The invention discloses efficient wrinkle removing equipment for synthetic leather processing. The equipment comprises a heating roller, a compressing roller, a humidifying box, a steam nozzle which is communicated with an ultrasonic water atomization generator, and a steam partition plate. The heating roller comprises an inner cylinder and an electric heating wire. A first insulating material is wound outside the inner cylinder. The electric heating wire is wound outside the first insulating material on the inner cylinder. The electric heating wire close to the two ends of the inner cylinder is wound densely, the electric heating wire close to the center of the inner cylinder is wound sparsely, and the sparse and dense condition is in transition gradually. The inner cylinder is sleeved with a roller ring. When the electric heating wire gives out heat, the temperature of the two ends of the roller ring is highest, and the temperature of the center of the roller ring is lowest. The steam partition plate is in an arc shape and is mounted in the humidifying box. Humidifying spaces defined by the steam partition plate, the humidifying box and cloth can meet the condition that when the cloth penetrates through the humidifying spaces, the time for the two ends of the cloth to make contact with atomization steam is long, and the humidifying amount is large; the time for the position close to the center of the cloth to make contact with atomization steam is short, and the humidifying amount is small. The efficient wrinkle removing equipment has the advantages that electricity and water are saved, high-temperature, high-humidity and high-pressure shaping is realized, and the precise control effect is good.

Description

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

[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. When coating, the center of the cloth is easy to tighten, and the two ends of the width of the cloth are relatively loose. Therefore, the two ends of the cloth are not easy to flatten, and the probability of quality problems at both ends of the synthetic leather after coating is high.
