Heating device in continuous winding type glass fiber reinforced plastic pipeline mold

The utility model discloses a heating device in a continuous winding type glass fiber reinforced plastic pipeline mold. The heating device comprises a main shaft; a slip sheet; the heating pipeline loop comprises long heating pipes arranged in the two sliding sheets, and the length direction of the long heating pipes extends in the axial direction of the main shaft; the far-end openings and the near-end openings of the two long heating pipes are connected in a sealed mode through short heating pipes perpendicular to the axial direction of the main shaft, and a closed pipeline loop is formed. The one-way valve is arranged in the heating pipeline loop; the heating equipment is arranged on the heating pipeline loop; and the heating pipeline loop is filled with a liquid heating medium and air. The scheme has the beneficial effects that the heating pipeline loop is arranged on the sliding sheet, so that the sliding sheet can be stably heated, and a brand new mode of solidifying the pipeline from inside to outside
