Description

Drum sprayer

technical field

The utility model belongs to the technical field of spraying equipment, in particular to a drum type spraying machine.

Background technique

Many electronic accessories or products on the market, such as electromagnets, need to be sprayed with a certain thickness of paint on the surface to achieve anti-corrosion, anti-rust, wear-resistant or insulation purposes. The paint materials mainly include epoxy resin, pigments and solvents. The pigments are solid granular objects, so they need solvents to dissolve and adhere to the surface of the product. At present, the coatings formulated with domestic solvents are very thin every time they are sprayed on the product, which cannot meet the requirements of anti-corrosion, anti-rust, wear-resistant or insulation of the product. Therefore, it is necessary to dry the coating and repeat it many times. Secondary spraying and drying operations. Therefore, there are many processes, and a large amount of time and labor are required, which is not conducive to reducing production costs and improving production efficiency.

In view of the above problems, we have introduced foreign advanced solvents, which can make the paint adhered to the product thicker after each spraying, so the number of spraying and drying operations can be significantly reduced, thereby saving time and human purpose. However, this solvent is different from existing domestic solvents in that it needs heating to dissolve the solid pigment, and the solvent needs to be heated for this reason. Of course, after all the materials of the coating can be prepared, they can be uniformly heated into a coating that can be sprayed directly, and then sprayed on the coating. However, this has a big disadvantage, that is, when the spraying work needs to be suspended due to special circumstances or workers rest , the paint will cool and solidify in the pipe, which will cause serious damage to the equipment.

The drum-type spraying machine can evenly coat the paint on the surface of the product by placing the product in a continuously rotating drum. At present, the drum spraying machines on the market use paint made of domestic solvents. Therefore, the paint coated on the surface of the product is very thin each time, and the thickness is about 10um each time. Take the product out of the cylinder, dry it, and then put it back into the cylinder for coating and drying. Only after repeating this many times can the required coating thickness of the product be met. The process is cumbersome, consumes a lot of labor, and the production efficiency is low .

Therefore, in order to apply coatings made of foreign advanced solvents and reduce the number of times of coating and drying products, it is necessary to develop a set of machines that can heat and spray products at the same time.
