Description

Technical field [0001] The invention relates to a textile machine, in particular to a new type of calender, which is used for the post-treatment of textile articles. Background technique [0002] The calender is mainly used for surface treatment of layered materials to achieve better physical and chemical properties. For example, the Chinese patent CN2535432Y announced on February 12, 2003 discloses a soft calender, which includes a main machine, a hydraulic system, an electric control system and a heating system. The main machine includes a frame, a hard roller, a soft roller, and a transmission device. The hard roller It is a heat roller and is connected to the heating system. The soft roller is an elastic soft roller and is connected to a hydraulic system. The hard roller and the soft roller are respectively rotatably arranged on the frame and driven by a transmission device. The hard roller and the soft roller are radially outside. The walls are in contact with each other to...

AI Technical Summary

Problems solved by technology

The early hard roll generally adopts a hollow columnar structure. The axial ends of the hard roll are rotatably set on the frame through bearings. The hollow part of the hard roll is equipped with an electric heating device. Power supply connection, the main disadvantage of this kind of electric heating hard roll is that there is a gap between the electric heating device and the hard roll, the heat transfer efficiency is low, and the temperature of the outer wall of the hard roll is unevenly distributed along the circumferential direction; the existing hard roll uses heat transfer oil as Heat conduction medium, the inner cavity of the hard roll is filled with heat conduction oil, so that the electric heating device can better transfer heat to the outer wall of the hard roll through the heat conduction oil

But this kind of hard roll heated by heat transfer oil also has disadvantages. One is that when filling the cavity of the hard roll with heat transfer oil, the amount of heat transfer oil added cannot be controlled. If too much heat transfer oil is added, when heating, the heat conduction The hard roll bursts when the oil is heated and expands; the second is that the temperature of the heat transfer oil near the heating device is high, while the temperature of the part away from the heating device is low, which will cause uneven heating of the outer wall of the hard roll along the circumferential direction and affect the calendering effect; The third is that the connecting part between the hard roller and the sealing device is easy to crack due to long-term thermal expansion and contraction, resulting in seal failure, and the heat transfer oil leaks from the crack
