Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to a high-safety paint spraying equipment. Background Art

[0002] Paint is a material that is applied to the surface of an object to be protected or decorated and can form a continuous film that is firmly attached to the object. It is usually a viscous liquid made of resin, oil or emulsion, with or without pigments, fillers, and corresponding additives, and is prepared with organic solvents or water. Paint not only has protective and decorative effects, but also can give objects specific functions, such as insulation, rust prevention, mildew resistance, heat resistance, etc. In the prior art, workers are required to climb up to spray the wall, which makes it difficult to ensure the safety of the workers.

[0003] The existing spraying equipment can only spray vertical walls. When it is necessary to spray the ceiling of the room, its angle adjustment is inconvenient, which limits its scope of application. In addition, the paint contains many harmful substances, such as volatile organic compounds, formaldehyde, etc. These substances will be released into the air during the spraying process. If workers inhale these harmful substances for a long time, they may cause health problems such as respiratory system lesions, headaches, eye irritation, and insomnia. In view of this, we propose a high-safety paint spraying equipment and spraying process. Summary of the invention
