Description
Technical Field

[0034] Working principle: During use, the transformer to be coated is transported by the guide table 4 to the processing seat 3 located at the loading position. The telescopic clamp 10 clamps and fixes the transformer to be coated on both sides of the processing seat 3. The electric pulley 12 at the bottom of the processing seat 3 moves in a circle along the annular slide rail 2, causing the processing seat 3 at the loading position to rotate to the coating position. The electric lifting column 7 drives the upper pressure seat 8 to move down and contact the top of the transformer. The upper pressure seat 8 with the rotating component 9 and the processing seat 3 at the coating position press and rotate the transformer relative to each other, thereby driving the film unloading motor 116 of the automatic coating mechanism 11 to unload the film and rotate it around the transformer. The transformer is coated with film. The processing seat 3 moves along the annular slide rail 2 via the electric pulley 12 at the bottom of the processing seat 3. The processing seat 3, which is holding the coated transformer in the coating process position, is rotated to the heat sealing process position located in the heat sealing machine box 13. The temperature is sensed by the temperature sensor 164, and the electric heating tube 163 is controlled to heat the air blower 162 to introduce airflow to the required temperature. The hot air is output to the air outlet plate 15 through the air duct 165. The rotatable transformer held by the processing seat 3 in the heat sealing process position can be heated and coated from all directions. After the coating process is completed, the processing seat 3, which is holding the heat-sealed transformer in the heat sealing sequence position, is rotated to the unloading process position to remove the transformer and complete the coating process.
