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

[0033] Now in conjunction with accompanying drawing, the present invention will be further described:

[0034] As shown in the figure, a tanning ironing heating equipment includes:

[0035] 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;

[0036] Also includes:

[0037] Electric heater is made up of electric heating wire 9, insulating frame 8 and heat collecting cover 7, and electric heater is installed on the frame and can heat roller ring 61, and electric heating wire 9 is wound on insulating frame 8, near the two ends of roller ring 61 The winding is dense, and the winding is sparse near the center of the roller ring 61, and the density changes gradually. The heat obtained by the two ends of the roller ring 61 is high and the temperature is high, and the heat obtained by the center of the roller ring 61 is low and the temperature is low, and the temp...

Abstract

The invention discloses ironing and heating equipment for tanning, which comprises an electric heater, wherein the electric heater is composed of an electric heating wire, an insulating frame and a heat concentrating cover; the electric heater is installed on a machine frame and can be used for heating a roller ring; the electric heating wire is wound on the insulating frame, is wound densely at positions close to both ends of the roller ring, and is wound sparsely at a position close to the center of the roller ring, and the density changes gradually; two ends of the roller ring obtain more heat quantity and are higher in temperature, the center of the roller ring obtains fewer heat quantity and is lower in temperature, and the temperature changes gradually; a heating roller is an electric heating roller or an oil heating roller which heats evenly; the insulating frame is made from a ceramic plate, and the ceramic plate is provided with embossments for hooking the electric heating wire; and the center of the roller ring refers to a distance J, the electric heating wire is evenly wound within the distance J, and the corresponding temperature of the center of the roller ring is identical. The ironing and heating equipment for tanning has the beneficial effects of reasonable structure, low cost, heat energy, water and electricity conservation, sectional high temperature setting and good precise control effect.
