Humidifying equipment for tanning

Abstract

The invention discloses humidifying equipment for tanning. The humidifying equipment comprises a spraying pipe having two sealed ends and arranged over cloth. An inlet is formed in center of the spraying pipe; the inlet is communicated with a ultrasonic wave water atomization generator; a plurality of nozzles are arranged on the pipe wall of the spraying pipe; the plurality of nozzles are arranged as follow: the closer the nozzles is to the center of the spraying pipe, the greater the distance is; the distance is the smallest when the nozzles are close to two ends of the spraying pipe; the distance is gradually changed; when cloth passes under the nozzles, the two ends of the cloth have high humidity due to the contact with the atomization air; the center of the cloth has low humidity; the humidity is gradually changed; a cover is fixed on the spraying pipe; and the cover is in a horn shape and forms humidifying areas together with the cloth. Atomization air diffusion can be reduced by the use of the technical scheme; a place where the cover is close to the center of the spraying pipe is provided with two separation plates; a non-humidifying area is formed between the two separation plates; no nozzles are arranged in the non-humidifying area; and the inlet is communicated with spraying holes of the two humidifying areas. The beneficial effects of the humidifying equipment for tanning are that the humidifying area is electricity-water-saving; humidifying and crinkle-removing can be conducted at different stages; and great and accurate control can be achieved.

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.

[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
