Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spraying operation, in particular to an automatic spraying device for petroleum and chemical steel drum production. BACKGROUND

[0002] The steel drum produced by the factory is composed of a cylindrical barrel body and two upper and lower circular plates. In order to improve the service life of the steel drum, the inside and outside of the steel drum need to be sprayed with paint. In order to reasonably utilize resources and avoid waste, the steel drums used in the fields of petroleum, chemical industry and the like need to be renewed and reused. In the process of renewing the old steel drum, the surface, bottom and cover of the steel drum need to be sprayed with protective paint. The types of metal plates include steel, aluminum, copper, stainless steel, aluminum alloy and the like. Generally, the metal is oxidized and rusted in the air. Rust removal is a method for removing rust on the surface of the metal by various means. The rust on the metal is the oxide of the metal. The strength and quality of the rusted steel plate will decrease, and the rust will slowly penetrate into the interior.

[0003] Traditionally, a fixed spray gun or an operator holding a spray gun can be used. It is difficult for the fixed spray gun to perfectly cover the entire circumference of the cylindrical steel drum, and it is easy to produce a spraying blind area or a thin coating on both sides of the barrel body. The hand-held spraying completely depends on the skill and stability of the worker, and the phenomena of uneven paint film thickness, sagging, orange peel and the like frequently occur. Whether manual spraying or semi-automatic spraying, more auxiliary time is needed, and the effective operation time of actual spraying accounts for a low proportion. Manual spraying is slow and cannot be continuously operated. It is usually designed for a specific size of steel drum. Once the diameter or height of the steel drum changes, tedious mechanical adjustment needs to be carried out, such as moving the position of the spray gun, replacing the clamp and the like, or even another production line needs to be set up. This cannot adapt to the flexible production demand of small batch and multiple specifications, and the over-spraying phenomenon of manual spraying is very serious. SUMMARY
