Description

TECHNICAL FIELD

[0001] The utility model relates to the field of spraying coating, especially relates to a ceramic roller bar coating device for spraying. BACKGROUND

[0002] In order to effectively protect the ceramic roller bar, reduce unnecessary loss of the ceramic roller bar, and reduce the production cost of the ceramic enterprise. The ceramic enterprise will generally apply ceramic roller bar coating on the surface of the ceramic roller bar to form a protective layer, effectively reducing the adhesion and erosion of the glaze to the ceramic roller bar.

[0003] Forming a ceramic roller bar coating layer with uniform thickness is the key to effectively protecting the ceramic roller bar. At present, most ceramic enterprises rely on manual application of ceramic roller bar coating, and some use automatic roller bar coating machines. The main operation steps are to immerse the ceramic roller bar in a ceramic roller bar coating slurry pool and then take it out to dry, so that a ceramic roller bar coating protective layer is formed on the surface of the ceramic roller bar. However, during the process of taking the ceramic roller bar out of the ceramic roller bar coating slurry pool and drying, it is difficult to ensure that a coating layer with uniform thickness is formed on the surface of the ceramic roller bar due to the influence of the water absorption rate of the ceramic roller bar and the self-weight of the ceramic roller bar coating slurry, which greatly reduces the performance of the ceramic roller bar. Secondly, manual coating can harm the health of the operator due to the high dust in the working environment of the ceramic roller bar coating area, and it has high labor intensity, low work efficiency, and high production cost. Although the automatic roller bar coating machine can improve the working environment of the operator, reduce labor intensity, and improve work efficiency, its structure is complex, which also brings problems such as high production cost.
