Spraying room for quick color changing equipment

Abstract

The invention discloses a spraying room for quick color changing equipment. The spraying room comprises a spraying room body, a ventilation opening, an electrostatic filter layer and an air outlet, wherein a spraying cavity is arranged on the middle position inside the spraying room body; the ventilation opening is formed in one side of the spraying cavity; the air outlet is formed in the other side of the spraying cavity; the filter layer is arranged inside the ventilation opening; a filter element is arranged at the other side inside the air outlet; and a fan is arranged at the other side inside the air outlet. The spraying room realizes cleaning for powder inside the spraying cavity through an electric telescopic pole and a brush; the spraying cavity communicates with a powder recyclingcavity through a powder leaking slot, so that powder conveniently enters the powder recycling cavity for being recycled and utilized for a second time; an electrostatic filter layer can adsorb lightparticles, namely dust, in powder, so that dust impurities are prevented from being mixed into the powder to affect spraying quality; and secondary screening processing does not need to manually perform, so that the spraying room is simple in structure and is reasonable in design.

Description

technical field [0001] The invention belongs to the technical field of metal sheet metal surface treatment, and in particular relates to a spray booth for rapid color changing equipment. Background technique [0002] With the continuous development of society and the continuous strengthening of the world's environmental protection awareness, people's requirements for product quality are getting higher and higher. In addition to the basic performance of the product, the requirements for the durability, wear resistance and aesthetics of the product appearance are also mentioned. With the same level of product performance, ordinary coatings can no longer meet the above requirements. The electrostatic spraying process is widely used because of its strong wear resistance, strong surface adhesion, and uniform color. The spraying room production in the existing electrostatic spraying process The skills are becoming more and more sophisticated, but there are still some deficiencies ...

[0002] With the continuous development of society and the continuous strengthening of the world's environmental protection awareness, people's requirements for product quality are getting higher and higher. In addition to the basic performance of the product, the requirements for the durability, wear resistance and aesthetics of the product appearance are also mentioned. With the same level of product performance, ordinary coatings can no longer meet the above requirements. The electrostatic spraying process is widely used because of its strong wear resistance, strong surface adhesion, and uniform color. The spraying room production in the existing electrostatic spraying process Skills are becoming more and more sophisticated, but there are still some deficiencies that need to be improved

[0003] There are the following problems in the spraying room of the rapid color-changing equipment in the prior art: 1. At present, most of the spraying rooms of the rapid color-changing equipment are equipped with a powder recovery device, which is used to recycle the powder that is not adsorbed on the workpiece to avoid waste of powder resources , but part of the recovered powder contains impurities, and the direct supply of powder and spraying in the spray gun will easily affect the spraying quality of the workpiece. It needs secondary processing and screening before it can be used, which increases the operating cost of the enterprise; 2. In order to avoid the air not circulating in the spraying room The phenomenon of internal humidity occurs, most of the existing spraying rooms of color changing equipment are not in a fully enclosed space, but the circulation environment causes the powder to spill easily during powder spraying, resulting in a large amount of powder waste, and the powder also contains some harmful substances to the human body, which is easy to spill pollute the working environment and affect the health of the staff
