The plurality of wire grooves 7 on the roller 6 are evenly spaced in the horizontal direction, so that the four rollers 6 work together to synchronously coat multiple electromagnetic wire cores. There are four rollers 6 in total;

[0021] A plurality of drying cylinders 9 are fixed on one side of the film material pool 1 and are distributed at equal intervals in the horizontal direction. Every two adjacent drying cylinders 9 are connected by a connecting block 10. L-shaped positioning rods 8 are welded at both ends of the plurality of drying cylinders 9, and the positioning rods 8 are welded to the outer wall of the film material pool 1. The two ends of the connecting block 10 are respectively welded to two drying cylinders 9, so that the structure of the plurality of drying cylinders 9 remains stable, wherein three mounting grooves 11 are provided on the inner side of each drying cylinder 9, and the three mounting grooves 11 are distributed in a circular array along the central axis of the drying cylinder 9, and electric heating wires 12 are installed in the three mounting grooves 11, and the electric heating wires 12 require external power supply, and a discharge port 13 for discharging excess film material dripping from the electromagnetic wire core is provided under the plurality of drying cylinders 9;

[0022] A collecting hopper 14 is welded to the outer wall of the film material pool 1 on the side where the multiple drying cylinders 9 are located, wherein the collecting hopper 14 is located below the multiple drying cylinders 9 and is used to receive excess film material dripping from the multiple electromagnetic wire cores.
