Beschreibung
Zusammenfassung:	The utility model provides a coating shielding device and a coating system, the coating shielding device comprises a base, a first spray head and a second spray head, the base is used for bearing a coating piece and can rotate around a vertical central axis, the first spray head is located above the base and can spray shielding medicament downwards, and the second spray head is located above the base and can spray shielding medicament downwards. The second spray head is located on the front side of the base and can spray out the shielding agent towards the rear side, and the second spray head can move in the left-right direction. The film coating shielding device provided by the utility model is used for spraying a uniform shielding coating on a non-film-coated surface before the film coating of a film-coated piece is started, and the coating on the non-film-coated surface is effectively removed in a water-soluble manner after the film coating is finished. Therefore, the non-coated surface of the coated part
