Problems solved by technology
[0002] In the galvanizing process, it is necessary to use coating equipment to coat the surface of the plate with a passivating agent. The existing coating equipment includes two vertically arranged rubber rollers. The passivating agent is sprayed from the surface of the rubber rollers to the rubber rollers through a pneumatic diaphragm pump. The passivating agent is applied from the rubber roller to the plate squeezed between the two rubber rollers. At present, the following disadvantages exist: the longitudinal extrusion force of the two rubber rollers on the plate is not enough, so that the passivating agent is not evenly coated, and the dosage Large, and the coating thickness cannot be adjusted, and the product quality cannot be adjusted according to the required production requirements

The invention relates to passivation solution coating equipment convenient to adjust coating thickness. The coating equipment comprises an upper rigid roller, an upper rubber roller, a lower rubber roller and a lower rigid roller, which are sequentially arranged from top to bottom in the vertical direction and from left to right in the horizontal direction, wherein pneumatic diaphragm pumps are arranged between the upper rigid roller and the upper rubber roller, as well as between the lower rubber roller and the lower rigid roller; a plate passes through the space between the upper rubber roller and the lower rubber roller; pressure is provided for the upper rubber roller and the lower rubber roller through the upper rigid roller and the lower rigid roller; the projections of the upper rubber roller and the lower rubber roller are superposed in the horizontal direction; the plate undergoes sinuous movement when passing through the upper rubber roller and the lower rubber roller so that the pressure is uniform, the coating is uniform and a passivator is saved; the upper rigid roller, the upper rubber roller, the lower rubber roller and the lower rigid roller are respectively driven by different motors; through adjusting the rotation speed difference among the motors, the coating thickness is adjusted, so that convenience is brought to adjust the product quality.
