[0031] Specifically, the surface of the metal coil (for example, an aluminum coil) is sprayed with powder (for example, polyester powder), which can provide high light, matte, metallic texture and the like, and has strong decoration.

[0032] One end of the metal coil passes through the inside of the shell 2, and the one end of the metal coil can pass into an external processing equipment (for example, a curling processing equipment), and under the traction of the external processing equipment, the metal coil slowly and uniformly passes through the inside of the shell 2.

[0033] During the process, the spraying mechanism 3 operates, the powder is transported by compressed air, is charged by high-voltage static electricity, and the charged powder is atomized and sprayed out and is uniformly adsorbed on the surface of the grounded metal coil. At the same time, the recycling assembly 5 operates, and the unadsorbed powder is collected by the recycling device and is reused.

[0034] The curing assembly 40 processes the surface of the metal coil, under the action of the recycling assembly 5, external air rapidly flows through the surface of the metal coil through a through slot 21, so that the speed of curing is accelerated, and the process does not need to rely on external cooling equipment, has the advantages of low energy consumption, and reduces production cost.

[0035] In one embodiment of the utility model, as shown in Figure 2 The spraying mechanism 3 comprises a powder supply box 31, a first pipe body 32, a distribution pipe 33 and a plurality of spray guns 34.
