[0020] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0021] Example: See Figure 1-4 In order to solve the problems existing in the current anti-corrosion operation using manual spraying, ensure the overall anti-corrosion coating effect of the packaging carton and increase the efficiency, a packaging carton anti-corrosion coating device is provided, including a bottom plate 1 and a conveyor belt 2, the conveyor belt 2 is fixedly installed on the upper end of the bottom plate 1, two coating boxes 3 are provided on both sides of the upper end of the bottom plate 1, and the two coating boxes 3 are provided with a coating drying structure, and a flip structure is provided on one side of the upper end of the bottom plate 1;

[0022] The coating and drying structure includes: a hot air blower 4, an air inlet screen 5, four guide rods 6, a first cylinder 7, a coating frame 8, four electric rollers 9, a coating belt 10 and a glue spreading assembly;

[0023] The hot air blower 4 is fixedly installed on one side of the coating box 3, the air inlet mesh plate 5 is embedded in the upper end of the wall of one side of the coating box 3, the four guide rods 6 are respectively installed on both sides of the coating box 3, the first cylinder 7 is fixedly installed on the upper end of the coating box 3, the two ends of the coating frame 8 are movably mounted on the upper ends of the four guide rods 6, the four electric rollers 9 are respectively installed on both sides of the coating frame 8, the coating tape 10 is movably mounted on the upper ends of the four electric rollers 9, and the glue spreading assembly is fixedly installed on one side of the upper end of the coating frame 8, and is in contact with the outer side of the upper end of the coating tape 10.

[0024] When in use, the packaging cartons can be continuously conveyed by the provided conveyor belt 2. When conveyed to the coating box 3, the glue spreading component located at the upper end of the coating frame 8 applies the anti-corrosion coating to the upper end of the coating belt 10. The four built-in electric rollers 9 work to drive the coating belt 10 to rotate, and the built-in first cylinder 7 works to make the lower end of the coating belt 10 contact the packaging carton at the upper end of the conveyor belt 2, and the upper surface of the packaging carton is coated. After the treatment is completed, the coating is dried by the hot air blower 4 to ensure the stability of the coating of the packaging carton. As the conveyor belt 2 continues to work, the coating is dried by the hot air blower 4 to ensure the stability of the coating of the packaging carton. The set flipping structure performs the flipping operation on the packaging carton. After the flipping is completed, the other side of the packaging carton is coated and dried again by another coating and drying structure to ensure the overall anti-corrosion effect of the packaging carton. The set guide rod 6 can effectively ensure the lifting and lowering stability of the coating frame 8. Through the above operation, the coating and flipping functions of the packaging carton can be realized, and the double-sided coating operation of the packaging carton can be realized.
