Abstract

The invention relates to a device and a method for spraying a coating. The device for spraying the coating comprises a spraying box (1), a coating recycling box (2), a coating pump (3) and an air blower, wherein the upper end of the spraying box (1) and the upper end of the coating recycling box (2) are communicated through a first connecting pipe (5) and are closed; the middle of the spraying box (1) is provided with a feed inlet (11) through which the spraying box (1) is communicated with external atmosphere; the coating is accommodated in the part of the spraying box (1), which is below the feed inlet (11); an inlet of the coating pump (3) is connected with the coating recycling box (2); an outlet of the coating pump (3) is connected with the spraying box (1), so that the recycled coating in the coating recycling box (2) is conveyed to the part below the spraying box; and an air blower (4) is connected with the upper part of the coating recycling box (2) and exhausts air. By the device and the method, the coating can be uniformly distributed on the surface of a workpiece, and the coating can be effectively prevented from being diffused in the air outside the device, so that the air is prevented from being polluted, health of spraying personnel is guaranteed, and the coating is fully utilized simultaneously.

Description

technical field [0001] The invention belongs to the technical field of spraying, in particular to a paint spraying device and method. Background technique [0002] At present, the existing paint spraying process mainly uses a spray gun to atomize the paint and then sprays the workpiece; however, the inventors have found that the existing paint spraying process has at least the following disadvantages: [0003] First, if figure 1 As shown, after the paint is sprayed from the spray gun 1, a fan-shaped atomization area A will be formed; only a part of the atomized paint in the atomization area A will adhere to the workpiece 2, while the rest of the atomized paint will be partially Diffuse directly into the air, and some are splashed into the air after impacting the surface of the workpiece 2; under the existing technical conditions, there is no good way to recycle these atomized coatings diffused into the air, so this The spraying process will not only cause a serious waste o...
