[0002] Tracing paper is a common type of drawing paper in mechanical drawing. Its specifications are consistent with international standard drawing paper. It is light in weight, semi-transparent in color, and has good wear resistance, water resistance and ink absorption. The coating production process involves coating a coating on a workpiece such as a plate. Specifically for tracing paper, the purposes of coating include but are not limited to anti-corrosion, insulation and decoration. By covering a thin plastic layer on the surface of tracing paper, the paper can be effectively protected from damage, and at the same time, its use value and aesthetics can be increased.

[0003] The patent with the publication number CN 209491003U discloses a coating device for oil-resistant tracing paper. This device has the advantages of uniform and dense coating. The oil-resistant tracing paper has good oil resistance, but this device does not have an adjustment mechanism and cannot coat tracing paper with different thicknesses. Moreover, this coating device for oil-resistant tracing paper is not designed with a deviation correction mechanism and is prone to deviation during coating. Summary of the Utility Model
