Abstract

The invention provides spraying equipment, which comprises a rack and a spraying device. A motor and a conveying crawler belt driven by the motor are arranged on the rack; a metal thin sheet is conveyed on the conveying crawler belt; a spraying device is arranged above the conveying crawler belt and is arranged on a fixed support; the fixed support is fixedly connected with one side of the rack; the spraying device comprises a high voltage static spray gun, a powder supply barrel, a high voltage static device and a controller; a high voltage generator is arranged in the high voltage static spray gun; a powder pipe and a gun pipe are connected onto the high voltage static spray gun; the powder pipe is connected with the powder supply barrel; the gun pipe is connected with the high voltage generator and the high voltage static device; and the high voltage generator is connected with the controller. The spraying equipment provided by the invention has the beneficial effects that the highvoltage static spray gun can be used for enabling powder to uniformly adsorb on a surface of the metal thin sheet during work so as to obtain a smooth surface, and a spraying effect is better throughthe arranged controller.

Description

technical field [0001] The invention relates to the technical field of metal can processing, in particular to a spraying equipment. Background technique [0002] Packaging metal cans made of thin metal sheets are a category of packaging containers commonly used at present. The can body of this metal can is formed by welding the joint seam with a high-frequency resistance seam welding machine after bending the metal sheet. . The surface of the metal sheet for canning is generally sprayed with an anti-corrosion protective layer before being cut into small squares, then rolled into a circle, and processed into a tank body through welding, recoating, necking, sealing and other processes. In the process of spraying the surface of the metal sheet, uneven spraying often occurs, causing the surface of the tank body to be rough and beautiful, and affecting product quality. Contents of the invention [0003] The purpose of the present invention is to provide a spraying equipment w...
