Background
At present, electrostatic powder spraying is commonly adopted in the world to carry out surface spraying on metal structural parts, cold-rolled steel plates, galvanized steel plates and aluminum plates.
Electrostatic powder spraying is performed by a plurality of spray guns. A high-voltage electrostatic generator is arranged in the gun body of the spray gun, and when electrostatic powder is sprayed out of the nozzle, an electrostatic field is generated by the electrode. The electrode is typically a straight wire and extends a little to the nozzle outlet, the tip of the wire being sharp. A high-voltage electrostatic field is generated by concentrating one point at the tip, and an electric charge is added to the powder discharged from the nozzle.
For some existing sprayers adopting line source electrodes and annular umbrella-shaped nozzles, the powder spraying amount of the sprayers is larger than that of the sprayers. If a plurality of spray guns of this type are arranged in a row and are arranged according to a certain width, a sheet material of the same width can also be sprayed. But two of the lances in a row cannot be closely spaced for two reasons. Firstly, a spray gun nozzle electrode is provided with high-voltage static electricity, when two nozzles are close in distance, a potential difference exists between the two nozzles due to electric leakage or other reasons of one nozzle, so that a discharge phenomenon is generated, the potential of the nozzle can be lost or reduced, the charging capacity is reduced, and the powder charging effect is poor, so that the spraying is influenced; meanwhile, discharge is an unsafe phenomenon in spraying work, and powder burning or explosion can be caused.
In the prior art, for example, patent application No. 201510081079. X, entitled line source electrode electrostatic powder sprayers, discloses reducing the overlap of sprayed coating between adjacent sprayers by changing the shape of the internal caliber of the sprayers. However, the distance between the spray heads is too close, which cannot fundamentally solve the problem of potential difference caused by voltage leakage.
In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.

The power-on roller 300 has a plurality of positive charges, which can attract the paint with negative charges sprayed by the electrostatic spray head, and the paint falls onto the coiled material in the attracted process to realize the spraying effect of the coiled material.
In the case of the metal conductive coil 400 (metal coil), the product is charged (with positive charges) by connecting the coil with the conductive path, and the energizing roller 300 is not required to be provided inside the apparatus. In particular, in this example, the support roller 101 may be connected to a charge generator (in a manner not shown in the drawings) to provide additional charge to the support roller 101 during the transfer support of the web.

And does not affect the spray effect (the distance of the spray range between adjacent atomising cartridges 2 does not increase).
Referring to fig. 3 and 4, in addition, the connecting pipe 3 of the present application adopts a ten-thousand-joint pipe capable of deforming (the ten-thousand-joint pipe is an existing pipe structure, for example, some desk lamp supporting pipes, water supply pipelines in a kitchen or a bathroom are all related), the ten-thousand-joint pipe has a good plastic deformation effect, and after the ten-thousand-joint pipe is deformed by external force, the ten-thousand-joint pipe still maintains the deformation effect after the external force is removed.
