Abstract

The invention provides an efficient air returning structure for a painting production line solidifying device, and belongs to the technical field of painting equipment. The efficient air returning structure solves the technical problems that in the prior art, returned air is high in powder content, and the follow-up processing working procedure is high in pressure. The efficient air returning structure comprises an outer wall and an inner wall, an air returning cavity is formed between the outer wall and the inner wall, air inlets are formed in the top of the outer wall and communicated with the interior of the inner wall, air returning openings are formed in the side wall of the inner wall and communicated with the air returning cavity, the bottom of the air returning cavity is downwards sunken to form a settling collecting area, and a powder settling mechanism capable of enabling powder to be settled is further arranged in the air returning cavity. According to the efficient air returning structure, the temperature in an air returning structure is even, painting is facilitated, and cost can be effectively reduced.

Description

technical field

[0001] The invention belongs to the technical field of spraying equipment, and relates to a high-efficiency return air structure for a curing device in a coating production line. Background technique

[0002] Electrostatic powder spraying technology is a new coating technology that has developed rapidly in recent years. It is characterized by energy saving, non-polluting process, simple powder, recyclable and easy automation, and the coating is beautiful, durable and durable. The new development direction of the industry. In the electrostatic spraying operation, it is usually necessary to place the profile adsorbed with resin powder in a drying room to be melted and fixed so that the surface of the profile is covered with a complete resin coating. The drying room usually uses hot air circulation to provide heat energy for powder melting, and needs to be Hot air circulation must have a return air structure.

[0003] The existing return air structure such as ...
