Description

Technical Field

[0001] The utility model belongs to the field of coating spraying equipment, and in particular relates to a coating spraying mechanism for the inner wall of a thermos cup. Background Art

[0002] Generally, it is a water container made of ceramic or stainless steel with a vacuum layer. It has a cover on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids inside to achieve the purpose of heat preservation. In order to avoid the formation of scale for a long time, it is generally necessary to spray a layer of coating on the inner wall of the thermos cup to increase the service life of the water cup and reduce the scale generated by use. In order to achieve a better spraying effect, the water cup generally needs to be sandblasted before being sprayed to increase the surface roughness of the inner wall of the water cup. In order to make the paint better fit the water cup during the later spraying, the traditional operation method is mostly manual operation, which is inefficient, and the dust generated by sandblasting also affects the operator's body. After manual sandblasting, the inner wall of the cup is prone to residual gravel, or the cup after sandblasting is not transferred in time, resulting in gravel entering the cup after sandblasting during the later sandblasting. During spraying, the residual gravel is directly covered by the paint, reducing the product yield. Therefore, a thermos cup inner wall coating spraying mechanism that can automatically transfer the process and automatically sandblast and spray is required. Utility Model Content
