As shown in fig. 1 to 6, this embodiment discloses a fully coated hook for powder electrostatic spraying, which comprises a hook body 1 and an insulating layer 2 coated on the outer side of the hook body 1, wherein the hook body 1 comprises an upper hook portion 11 for connecting a hanger 3, a lower hook portion 12 for connecting a workpiece and a connecting portion 13 for extending the workpiece into a spraying chamber to perform powder electrostatic spraying, two ends of the connecting portion 13 are respectively connected with the upper hook portion 11 and the lower hook portion 12, the outer side wall of the connecting portion 13 is fully coated with the insulating layer 2, and the hook body 1 is made of a conductive material. Preferably, the hook body 1 is made of an aluminum alloy material, and the insulating layer 2 is made of silica gel or polytetrafluoroethylene material. When the hook body 1 is made of an aluminum alloy material, the hook body 1 has good electric conductivity, so that the adsorption performance of workpiece spraying processing is ensured, and the spraying effect of the workpiece is better; in addition, the hook body 1 also has higher structural strength and lighter weight, can reduce the working energy consumption of a suspension conveying line, and meanwhile, the hook body 1 also has better high-temperature resistance and acid-alkali corrosion resistance. When the insulating layer 2 is made of silica gel or polytetrafluoroethylene material, the insulating layer 2 has better insulating property and better high-temperature resistance, acid and alkali corrosion resistance; the better the insulating property of the insulating layer 2 is, the less the surface of the insulating layer is easy to adsorb spraying powder, the area of the hook body 1, from which the spraying powder needs to be removed, is reduced, and the powder coating rate of a product can be improved. Because the workpiece is required to be subjected to a high-temperature curing process in the powder electrostatic spraying process, the hook body 1 and the insulating layer 2 are required to have high-temperature resistance; the powder used in spraying may involve acidic and alkaline coating powder, and the impurity on the surface of the workpiece is removed by pickling or the like before the workpiece is sprayed, so that the hook body 1 and the insulating layer 2 are required to have acid and alkali corrosion resistance.
In this embodiment, in order to further reduce the adhesion of the insulating layer 2 to the coating powder, the surface roughness Ra of the insulating layer 2 is 0.2 μm or less, and when the surface of the insulating layer 2 is sufficiently smooth, the coating particles adhering to the surface of the insulating layer 2 can be reduced.
In this embodiment, the upper hook 11 and the lower hook 12 are both hook-shaped structures.
In this embodiment, the hanger further comprises a plurality of hangers 3 arranged along the conveying direction of the hanging conveying belt 4, a distance plate 5 is arranged between adjacent hangers 3, and the adjacent hangers 3 are spaced apart by a fixed distance through the distance plate 5.

The top of the hanging ring 32 passes through the distance plate 5 and enters the clamping groove 33, and the bridging component 31 and the hanging ring 32 are locked and fixed through the positioning pin 34. The head of the locating pin 34 is abutted to the outer side of one connecting bridge 311, the rod part of the locating pin 34 passes through the bridging component 31 and the hanging ring 32, the cotter pin 35 radially passes through the rod part of the locating pin 34, and the cotter pin 35 is abutted to the outer side of the other connecting bridge 311, so that the bridging component 31 and the hanging ring 32 are very conveniently and fixedly connected.
