Heating roller of ironing equipment based on synthetic leather processing

Abstract

The invention discloses a heating roller of ironing equipment based on synthetic leather processing. The heating roller comprises a roller ring, two roller end surfaces and a roller shaft, wherein the roller shaft is mounted on a rack through a bearing, and high-temperature oil in the heating roller is communicated with a heating oil tank through an oil pump; a round heat-collection barrel comprises a hollow body and a plurality of heat-collection pieces arranged on the inner wall of the hollow body, the outer surface of the hollow body is tightly attached to the inner wall of the roller ring, each heat-collection piece adopts a structure of symmetrical double triangles, apexes of the double triangles are close to the center of the hollow body, the round heat-collection barrel can absorb heat from the high-temperature oil and transfer the heat to the roller ring, the temperature of positions close to two ends of the roller ring is high, the temperature of a position close to the center of the roller ring is low, and the temperature changes gradually. According to the fact that the apexes of the double triangles of each heat-collection piece are close to the center of the hollow body, the center refers to a distance J, and the temperature of the corresponding roller ring center is equal in the distance J. The heating roller of the ironing equipment based on synthetic leather processing has the benefits of reasonable structure, low cost, electricity saving, water saving, high-temperature, high-humidity and high-pressure setting and good accuracy control effect.

Description

technical field [0001] The invention relates to an equipment for processing synthetic leather and ironing corrugated cloth. 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, ther...

[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
