A fully automatic assembly line system for electrostatic powder coating

Abstract

The invention discloses a fully automatic assembly line system for electrostatic powder coating, which comprises a fixed base, a non-contact powder bin arranged on the base, a powder material recovery system arranged on the non-contact powder bin, and a device fixedly connected to the fixed base. Cylindrical coating silo, suspension conveying mechanism located in the cylindrical coating silo, primary powder spraying structure located in the cylindrical coating silo, secondary powder spraying structure located in the rear side of the primary powder spraying structure The powder spraying structure and the leveling mechanism located in the secondary powder spraying structure; two spraying structures are set to expand the spraying area between the flowing water, and the conveying speed of the suspended conveying structure can be further accelerated, thereby improving the working efficiency; setting A powder recovery system is installed, which can realize the timely recovery and utilization of powder in conjunction with the drum-type coating silo, reducing the waste of powder and saving costs.

Description

technical field [0001] The invention belongs to the technical field of electrostatic powder coating, and in particular relates to an automatic assembly line system for electrostatic powder coating. Background technique [0002] Electrostatic powder spraying is commonly known as "electrostatic spraying"; electrostatic powder spraying uses a coating machine with an atomizing nozzle (to atomize the paint) and a discharge level (to generate electricity and current) to atomize the paint, apply a charge to it, and connect the electrode and the paint. An electric field is formed between the objects to be coated, and the electrostatic adsorption is used for coating; the existing electrostatic coating equipment on the market generally uses a single row of array spray guns to spray on both sides at the same time, so that the coating of the workpiece can be completed at one time; this spraying method It is often necessary to spray twice or even three times the amount of powder that exc...

[0002] Electrostatic powder spraying is commonly known as "electrostatic spraying"; electrostatic powder spraying uses a coating machine with an atomizing nozzle (to atomize the paint) and a discharge level (to generate electricity and current) to atomize the paint, apply a charge to it, and connect the electrode and the paint. An electric field is formed between the objects to be coated, and the electrostatic adsorption is used for coating; the existing electrostatic coating equipment on the market generally uses a single row of array spray guns to spray on both sides at the same time, so that the coating of the workpiece can be completed at one time; this spraying method It is often necessary to spray twice or even three times the amount of powder that exceeds the amount of coating at one time to ensure that there is no blank area for coating, so that a large amount of powder will accumulate at the bottom of the coating chamber, which needs to be recycled, screened and repainted regularly. Utilization increases the workload; at the same time, this coating method is more friendly to plate workpieces, and the coating effect on polyhedrons and irregular shapes is poor, and the function is relatively single
