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

[0025] Now in conjunction with accompanying drawing, the present invention will be further described:

[0026] As shown in the figure, a water-saving and power-saving synthetic leather processing and wrinkle-removing equipment includes:

[0027] 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. The high temperature oil 67 in the heating roller 6 communicates with the heating oil tank controlled by electricity through an oil pump. The high-temperature oil flows in from the central inlet 641 of the roller shaft 64, 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 can be connected with the oil pipeline with a swivel joint.

Abstract

The invention discloses synthetic leather processing and wrinkle-removing equipment capable of saving water and electricity. The equipment comprises a heating roller and a pressing roller, which cooperates with the heating roller, and also comprises a spray pipe. Two ends of the spray pipe are sealed, the spray pipe is arranged above cloth, the center of the spray pipe is provided with an inlet, the inlet is communicated with an ultrasonic water atomization generator, two V-shaped spray holes are symmetrically arranged in the wall of the spray pipe, the sharp part of each V shape is close to the center of the spray pipe; when cloth goes through the space under the spray holes, the humidity of atomized gas that contacts two ends of the cloth is high, and the humidity changes gradually. The equipment comprises a heat trapping barrel, which is composed of a hollow body and a plurality of heat trapping sheets arranged on the internal wall of the hollow body. The external surface of the hollow body is tightly attached on the inner wall of a roller ring. Each heat trapping sheet is in a symmetric double-triangular structure; and the sharp parts of double triangles are close to the center of the hollow body, so that the heat trapping barrel can absorb thermal energy from high temperature oil and transmit the thermal energy to the roller ring. The temperature of position that is closer to two ends of the roller ring is higher, and the temperature changes gradually. The provided equipment has the advantages that the electricity and water are saved, the moulding is carried out under conditions of high temperature, high humidity and high pressure, and the effect can be precisely controlled.
