Description

A kind of automatic spraying equipment on the surface of ceramic substrate

technical field

The utility model relates to a spraying device, in particular to an automatic spraying equipment for the surface of a ceramic substrate.

Background technique

The adhesion of the spraying medium (which can be red ink) to the surface of the existing ceramic substrate is achieved through the natural adhesion of the sponge roller. First, the worker places the ceramic substrate on the conveying roller, and the conveying roller conveys it. Through the red-painted area, a row of sponge rollers dipped in red ink in the red-painted area (a part of the sponge roller is soaked in red ink, and during the rotation of the roller, the entire surface of the sponge is covered with red ink) to roll the red ink. The ink adheres to the surface of the ceramic substrate, and then the ceramic substrate is transported out of the red-painted area to enter subsequent processes such as hot air drying. There are several disadvantages in the existing method of sponge roller adhesion. One is that the thickness of the coating is uneven, and some even do not adhere to the red ink. The main reason is that the flatness of the ceramic substrate is not good, and it is easy to make some ceramic substrates The surface cannot adhere to the red ink. In addition, because the thickness of the coating is determined by the amount of red ink absorbed by the sponge roller, and the amount of red ink absorbed by the sponge roller cannot be controlled, the thickness of the coating varies greatly; The ceramic substrates are placed on the conveying rollers without overlapping, resulting in low production efficiency, low spraying quality and high labor intensity.
