Heating roller for tanning ironing equipment

Abstract

The invention discloses a heating roller for tanning ironing equipment. The heating roller comprises a heating roller body. The heating roller body is composed of a roller ring, two roller end faces and a roller shaft. The roller shaft is installed on a machine frame through a bearing. High-temperature oil in the heating roller body is communicated with a heating oil tank through an oil pump. The heating roller further comprises a fence ring which is composed of multiple circumferential strips with the same width and length and at least two axial strips. The fence ring is tightly attached to the inner wall of the roller ring. The distance between the circumferential strips close to the two ends of the roller ring is larger than the distance between the circumferential strips close to the center of the roller ring. The distance gradually changes. The fence ring blocks the roller ring from absorbing heat. The temperature of the positions close to the two ends of the roller ring is high. The position close to the center of the roller ring is low. The temperature gradually changes. The center of the roller ring has a certain distance J; in the distance J, the distances between the circumferential strips are equal, and the temperature of the corresponding position in the center of the roller ring is uniform. The heating roller has the advantages of saving heat energy and water, achieving high-temperature high-pressure shaping and being accurate in control and good in effect.

Description

technical field [0001] The invention relates to a device for ironing corrugated cloth during synthetic leather processing. 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. However, there...

[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
