[0002] Powder-coated steel plate is a commonly used material in modern buildings. It has the characteristics of light weight, easy installation, and high corrosion resistance. The existing powder-coated steel plate is mainly finished by sacrificing the surface leveling effect and blowing compressed air during painting. Poor surface leveling effect and poor aesthetics; high energy consumption, more compressed air is used to complete; high cost, the purged powder cannot be recovered or recycled; pollutes the environment, and the purging powder is easy to overflow during the coating process. Low efficiency , the powder overflows and floats in the workshop, then falls to the ground, and then cleans, repeated work; it is also easy to cause color mixing on the back

Embodiment Construction
[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0030] Such as figure 1 , figure 2 As shown, an edge spraying shielding device for metal coils includes a drive wheel device 3 and a driven wheel device 2 installed on the left and right sides of the bracket 1, and the drive wheel device 3 is connected to the driven wheel device 2 through a timing belt 4 , the synchronous belt 4 is connected with the power supply.
[0031] The device is placed on both sides of the coil or plate, and the synchronous belt 4 is energized. The synchronous belt 4 is designed in combination with Faraday and the principle of physical shielding of dead corners without powdering, so as to reduce edge discharge during normal coating. The main content of Faraday's law of electromagnetic ind...
