Novel heating mantle

The invention provides a novel heating mantle. The novel heating mantle is used for solving the problems of slow heating and uneven heating of a conventional heating mantle. According to the technical scheme, the novel heating mantle comprises a rack and a heating mantle body, wherein the right end of the heating mantle body is rotatably fixed on the rack, the left end of the heating mantle body is downwards bent in the shape of 7, multiple thermocouples are longitudinally arranged at a bent opening at intervals, multiple groups of gold heating short pipes, which are longitudinally arranged at intervals and correspond to the thermocouples, are transversely arranged in the heating mantle body at the right of the thermocouples at intervals, multiple longitudinal gold heating pipes are transversely arranged in the heating mantle body at the right of the gold heating short pipes at intervals, multiple longitudinal quartz heating pipes are transversely arranged at intervals between the gold heating pipes and the right end of the heating mantle body, an air cylinder is arranged on the rack, a piston rod of the air cylinder is connected to the outer edge surface of a heat preserving side plate, and a mirror surface stainless steel plate is arranged on the inner top surface in the heating mantle body. The novel heating mantle can ensure the consistence of the plumpness of lines at the middle and the two sides of artificial leather and is capable of accurately controlling the temperature so as to enable the surface layer of the artificial leather to have an ideal temperature all the time.
