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

[0028] Now in conjunction with accompanying drawing, the present invention will be further described:

[0029] As shown in the figure, a heating roller of a tanning and wrinkling removal equipment includes:

[0030] The heating roller 6 is composed of a roller ring 61, two roller end faces 62 and a roller shaft 64. The roller shaft 64 is installed on the frame through a bearing 63, and the high-temperature oil 67 in the heating roller 6 communicates with the heating oil tank through an oil pump; The central inlet 641 of the roller shaft 64 flows in, the inner outlet hole 651 of the roller shaft 64 flows out into the heating roller 6, and then flows out from the inner inlet hole 652 of the roller shaft 64 through the center outlet 642 of the roller shaft 64, and the roller shaft 64 and the oil pipeline The connections can be made with swivel joints.

[0031] The center of the roll ring 61 refers to a distance J within which the circumferential strips 6621 have the same width a...

Abstract

The invention discloses a heating roller of tanning wrinkle removal equipment. The heating roller is composed of a roller ring, two roller end faces and a roller shaft. The roller shaft is mounted on a rack through bearings, and high-temperature oil in the heating roller is communicated with a heating oil tank through an oil pump. The heating roller further comprises a fence ring. The fence ring is composed of a plurality of peripheral strips which are the same in length and two or more axial strips and tightly attached to the inner wall of the roller ring, the center intervals of adjacent peripheral strips are the same, and the widths of the peripheral strips are gradually decreased from the center of the roller ring to the two ends of the roller ring; the high-temperature oil is conducted to the roller ring from the fence ring, the temperature is lowered, the temperatures of the positions close to the two ends of the roller ring are the highest, the temperature of the position close to the center of the roller ring is the lowest, and the temperatures gradually change. The roller ring center refers to a distance J, in the distance J, the widths of the peripheral strips are the same, and the temperatures, corresponding to the peripheral strips, of the center of the roller ring are the same. The heating roller has the advantages that the structure is reasonable, the cost is low, heat energy and water are saved, high-temperature high-pressure shaping is achieved,a dn the accurate control effect is good.
