Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, in particular to a drying room for steel plate spray painting. Background Art

[0002] Color-coated steel plates are made on a continuous unit with cold-rolled steel strips or galvanized steel strips as the substrate. After surface pretreatment, they are coated with one or more layers of liquid paint by roller coating, and then baked and cooled to obtain the resulting plate. After the existing color-coated steel plates are sprayed with paint, they will pass through a drying device to dry the paint.

[0003] A Chinese patent discloses a drying device for steel plate spraying, with the publication number CN215235618U, comprising a housing, a ring bar is provided in the housing, a plurality of paint lamps are provided on the inner side of the ring bar, a rectangular slider is fixedly connected to the left side of the ring bar, a moving mechanism for reciprocating the rectangular slider up and down is provided in the housing, a placement plate is horizontally provided in the housing, a placement slot is provided at the upper end of the placement plate, a plurality of placement mechanisms are provided in the placement slot, and a rotating mechanism for rotating the placement plate is provided in the housing. During use, the paint lamp is in a moving state, which can make the light source of the paint lamp and the heat it emits contact with the steel plate more evenly, ensuring the quality of the paint, and a rotating mechanism is also provided to further improve the uniformity of the paint.

[0004] However, it still has the following disadvantages: the device places the steel plate on the limit block and uses the paint lamp to dry the paint on the steel plate. However, when the placement plate rotates, only the outermost steel plate has the best paint effect, which makes the drying effect of the same batch of steel plates vary greatly. Therefore, we proposed a drying room for steel plate spray painting to solve this problem. Utility Model Content
