Description

Technical Field

[0001] The invention relates to a license plate erasing device. Background Art

[0002] The traditional license plate erasing device consists of a conveying roller, an erasing roller, and a plate pressing roller. The conveying roller conveys the license plate, and the plate pressing roller presses the license plate. The left and right sides of the erasing roller are in contact with the water-retaining roller. It is necessary to set a level gauge and adjust the tripod to ensure that the erasing roller and the plate are on the same level. The gap between the left and right water-retaining rollers and the erasing roller determines the amount of solvent in and out. The amount of solvent on the surface of the erasing roller is difficult to control. Too much will stain the license plate, and too little will not wipe off the paint on the embossed characters. The distance between the plate pressing roller and the conveying roller needs to be adjusted according to the different thicknesses of the license plate. The adjusting nut on the plate pressing roller needs to be adjusted frequently to ensure that the plate pressing roller can press the license plate. The upper and lower parts of each license plate require manual intervention, and contamination cannot be avoided. Summary of the invention
