Description

Technical Field

[0001] The utility model relates to the technical field of paint production equipment, in particular to a paint heating device for a paint production line. Background Art

[0002] The spraying construction of paint is generally carried out at room temperature, that is, the spraying environment temperature is consistent with the temperature of the paint. Paint heating spraying is to use a paint heater to heat the paint. Heating spraying is a novel paint spraying construction process. The viscosity of the paint is related to the temperature of the paint. As the temperature of the paint increases, its viscosity decreases. When we spray at room temperature, we adjust the viscosity of the paint by using low-viscosity solvents and high-viscosity paints. In fact, in the process of paint drying and film formation, the solvent is constantly evaporating. The solvent is not a film-forming substance, but is only to improve the construction and drying conditions. The volatile solvent not only damages the health of the spray construction workers, but also pollutes the atmospheric environment. Reducing the amount of solvent is a very concerned issue in spray construction. Paint heating is a solution to reduce the amount of solvent.

[0003] Existing paint heating equipment usually adds a stirring rod inside the heating box when in use to stir the paint raw materials in the heating box, thereby improving the heating effect. However, there is still uneven stirring and heating on the inner wall of the heating box, resulting in uneven stirring and heating of the paint and poor paint heating quality. Utility Model Content
