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

Abstract

The invention provides a novel press-polishing machine which can effectively avoid invalidation of sealing equipment, comprising a frame and hard roller which can rotate and is arranged on the frame; wherein, the hard roller comprises a roller body, two shaft heads, a supporting tube and a heating device, the roller body is of a prismatical hollow structure, the two shaft heads are respectively fixedly arranged at the two ends of a roller body along the axial direction, at least one sealing equipment is arranged between the shaft heads and the roller body, at least two fixed trays are arranged in the roller body along axial direction at intervals, the supporting tube penetrates through the radial central part of the fixed trays, the heating device is arranged in the supporting tube, an input end of the heating device is electrically connected with an external power source by a revolving connector, the sealing equipment comprises an internal tray, a ring-shaped copper tube and an external tray along the axial direction of the roller body, the lateral wall of the ring-shaped copper tube is respectively connected with the adjacent external side of an internal tray and internal side of the external tray and are combined into a whole, the other side of the internal tray and the other side of the external tray are respectively connected with the shaft head and the roller body and are combined into a whole.

Description

technical field [0001] The invention relates to a textile machine, in particular to a new type of calender, which is used for post-treatment of textile articles. Background technique [0002] Calenders are 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 host, a hydraulic system, an electrical control system, and a heating system. It is a hot roll and connected to the heating system. The soft roll is an elastic soft roll and connected to the hydraulic system. The hard roll and the soft roll are respectively rotatable on the frame and driven by the transmission device. The radial outer side between the hard roll and the soft roll The walls contact each other to compact the layered material passing therethrough. The Chinese patent CN2835304Y announced on November 8, 2006 discloses a calender cloth edge...
