Embodiment
Below in conjunction with embodiment and Figure of description, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
As shown in Figure 1, 2, electromagnetic heating roller device described in the utility model, comprise heater coil 4, the first nip roll 1 and the second pressure roller 2, wherein, heater coil 4 comprises that the first heater wire 5 and the second heater wire 6, the first heater wires 5 are fixedly connected with the second heater wire 6, are provided with the gap between the first nip roll 1 and the second pressure roller 2, the first heater wire 5 and the second heater wire 6 lay respectively at the both sides in described gap, and the first heater wire 5 and the second heater wire 6 are close to respectively the first nip roll 1 and the second pressure roller 6.
Wherein, the first nip roll 1 and the second pressure roller 2 are set to respectively solid formula pressure roller or open-core type pressure roller, can be common solid metal formula nip rolls, also can be the hollow metal formula nip rolls of heavy wall; Solid metal formula nip roll is used for the technique of long pressure roller, large pressure, guarantees that pressure roller has enough little deflection; Hollow metal formula nip roll is hollow structure, can lead in inside cooling water or warm water, with the temperature difference inside and outside the adjusting pressure roller, quick, the stable operating state that reaches balance.
The first nip roll 1 and the second pressure roller 2 all are set to the metal type pressure roller, can also be set to nonmetal formula pressure roller, they can divide inside and outside two-layer design, skin is designed to the composite construction that metal level, internal layer are designed to non-metallic layer, even can outermost layer be non-metallic layer, internal layer is the composite construction of metal level.
