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

Embodiment Construction

[0031] Now in conjunction with accompanying drawing, the present invention will be further described:

[0032] As shown in the figure, a segmental ironing tanning equipment includes:

[0033] The heating roller 6 is composed of a roller ring 61, two roller end faces 62 and a roller shaft 64, and the roller shaft 64 is installed on the frame through a bearing 63;

[0034] The pressure roller 5 cooperates with the heating roller 6 to pressurize and heat the cloth 1;

[0035] Also includes:

[0036] The nozzle 3 is closed at both ends and is located above the cloth 1. The center of the nozzle 3 is provided with an inlet 2, which is connected to the ultrasonic water atomization generator. The wall of the nozzle 3 is provided with two symmetrically arranged V The V-shaped nozzle hole 31 has a V-shaped tip close to the center of the nozzle pipe 3. When the cloth 1 passes under the nozzle hole 31, the two ends of the cloth 1 contact the atomized steam with high humidity, and the ce...

Abstract

The invention discloses a segmented ironing tanning device. The segmented ironing tanning device comprises a heating roller and a pressurizing roller which are used for heating and pressurizing cloth, and further comprises a spraying pipe and an electric heater. The spraying pipe is located above the cloth. An inlet is formed in the center of the spraying pipe and communicated with an ultrasonic water atomization generator. Two symmetrically-formed spraying holes in a V shape are formed in the pipe wall of the spraying pipe. The pointed part of the V shape is close to the center of the spraying pipe. When the cloth passes through the portion below the spraying holes, the humidity of atomization steam in contact with the two ends of the cloth is high, and humidity is gradually changed. The electric heater is composed of an electric heating wire, an insulation frame and a heat gathering cover. The electric heater is installed on a machine frame and can heat a roller ring. The electric heating wire is wound around the insulation frame, the wound portions, close to the two ends of the roller ring, of the electric heating wire are thick, the wound portions, close to the center of the roller ring, of the electric heating wire are thin, and the thin-thick degree is gradually changed. The heat obtained by the two ends of the roller ring is much, and the temperature of the two ends of the roller ring is high; the heat obtained by the center of the roller ring is little, and the temperature of the center of the roller ring is low; the temperature is gradually changed. The segmented ironing tanning device has the advantages that heat energy, water and electricity are saved, high-temperature, high-moisture and high-pressure shaping is carried out, accurate control is achieved, and the effect is good.
