Novel electric heating structure corrugated roll

The invention discloses a novel electric heating structure corrugated roll. The corrugated roll comprises a hollow cylinder and shaft heads which are fixedly and hermetically connected with the two ends of the cylinder, wherein the middle parts of the end faces of the shaft heads are provided with through holes; the through holes are communicated with the internal space of the cylinder; the end face of the cylinder is uniformly provided with a plurality of electric heating tube holes; electric heating tubes are arranged in the electric heating tube holes; the two ends of the electric heating tubes are connected with electric heating tube mounting disks; the electric heating tube mounting disks are fixedly connected with the end faces of the cylinder. The corrugated roll has the beneficial effects that the technical innovation is made for the conventional electric heating corrugated roll, the original central single-tube heating is changed into a multi-point heating mode on the inner layer of the cylinder of t
