Embodiment Construction
[0025] In order to further describe the present invention, the present invention will be further described below in conjunction with the examples.
[0026] As shown in the figure, a method for reducing the water on the edge of the color plate after the initial coating is cured, including a plate edge spraying system composed of a support tube 1, a welding fixing sleeve 2, a positioning handle 3, a galvanized outer sleeve 6 and an adjustable nozzle 7. The blowing device is characterized in that: the width of the color plate is 800mm-1600mm, the thickness is 0.3mm-2.0mm, and it is stitched at a certain distance; the adjustable nozzle is installed on the movable connecting rod. The cover can be adjusted according to the width of the production steel belt 5, and is fixed with a positioning handle 3; two welding fixed sleeves 2 are installed at the fixed position so that the nozzle connecting rod can be turned up and down so that the steel belt sewing head can be turned up automatic...

Abstract
The invention discloses a method for reducing edge water of a color plate after primary coating curing. The method comprises a plate edge spraying device consisting of adjustable nozzles, and is characterized in that the adjustable nozzles are left and right two movable sleeves mounted on a movable connecting rod and capable of adjusting according to the width of a produced steel strip, and are provided with positioning handles for fixing; two welding fixed sleeves are mounted in fixed positions to turn a nozzle connecting rod up and down for automatic turning up when a steel strip joint head comes; and the turning-up is automatically recovered under the gravity effect of the nozzle connecting rod after the joint head passes away; an angle between the nozzle connecting rod and the surface of the steel strip is always 30 degrees; and the nozzles are the adjustable nozzles. The method is characterized by comprising the manufacturing steps of: (1) drawing according to scene environment space sizes; (2) machining and use of needed spare parts and materials according to the drawing; (3) welding and manufacturing; and (4) field installation and debugging. The method has the advantages of solving the problems of chromatic aberration influence and paint removal due to plate edge water and improving the product quality and the production continuity.
Description
technical field [0001] The invention relates to the technical fields of roller coating and purging of various solid surfaces, and in particular to a method for reducing water on the edge of a color plate after the primary coating is cured. Various types of oil, lacquer and air spray can be carried out on the surface of objects by changing the medium and the nozzle. Background technique [0002] Primary and fine coating water quenching, which is used to spray desalted water on the surface of the strip after the strip steel comes out of the curing furnace to cool the strip steel. The water passes through the spiral plate heat exchanger to cool the desalinated water tank. Cool the strip steel out of the solidification furnace at a temperature above 200 degrees to below the process requirement of 50 degrees. If the water on the surface of the initial coating board enters the coating area, there will be missing coating or color difference coating, and the water on the surface of...
