When compressed air as carrier gas sends powder coating from powder supply barrel to spray cup and polar needle of spray gun through powder tube, it is connected with corona discharge produced by high-voltage negative electrode, and produces dense negative charge in its vicinity, and makes powder take negative charge. The powder with negative charges enters an electrostatic field with high electric field intensity, and the powder uniformly flies to the surface of the grounded workpiece under the dual actions of electrostatic force and carrier gas driving force to form a powder layer with uniform thickness. Then melted by reheating and cured to form a durable coating film.

The upper third round platform and the upper fourth round platform of the upper joint 8 are fixedly connected with the lower U-shaped block; the diameter of the third round platform is equal to that of the first round platform of the blind hole; the height of the third round platform is smaller than that of the first round platform of the blind hole; the diameter of the second round platform is equal to that of the fourth round platform; the height of the fourth round platform is larger than that of the second round platform of the blind hole; no. three round platforms are embedded in the No. one round platform.
The lower joint 9 consists of an upper U-shaped block and a lower block structure; the bottom of the lower joint 9 is provided with a sucker; the middle part of the lower joint 9 is provided with an inverted T-shaped section; the top of the lower joint 9 is hinged with the bottom of the upper joint 8.
The supporting legs 7 and the upper joints 8 can rotate around an axis in the horizontal direction, and the upper joints 8 and the lower joints 9 can be bent, so that the angles of the positioning table 6 and the suction cup can be adjusted at any time to align various dead angles.
The working principle is as follows: the nozzle 5 is replaced according to different use scenes, and when the distance is long and the spraying pressure is strong, the round-head nozzle 5 is used; when the distance is required to be short, the flat-head nozzle 5 is used when the spraying pressure is required to be slightly small. At the time of replacement, the magnet 1b can be replaced by a screw according to the circumstances, and a free replacement mode can be selected.
When the trigger 10d is pulled to perform painting, the switch element 10f is closed, and the high voltage generator 10e releases electric ions to one end of the wire, i.e., the nozzle opening, so that the electric ions are attached to the paint. The sheet metal part is connected with a negative electrode, so that the sheet metal part has an adsorption effect on positive point load.
When needing spraying special-shaped sheet metal component inside, only need to erect the rifle head from arbitrary angle and stretch into the inner space, press deformation button 10b in rifle body 10 side, cooperation rifle body inner space, transmission sliding key 10c can be because pressure level slides backward promptly, pulling tension steel wire 10a, slide towards the rear along the spout on sleeve pipe 3 through tension steel wire 10a pulling slider 3a, slider 3a can drive connecting rod 4 when sliding and take place the motion, make its pulling inner tube 2 realize the deformation effect around the pin joint, consequently, only need press deformation button 10b can realize the spraying in the inside four corners of spraying sheet metal component.
When the sheet metal component inner space that needs the spraying is darker, need pulling inner tube 2 and 3 both sides of sleeve pipe and can block the through-hole on the sleeve pipe 3 under spring deformation effect through No. two spacing balls 3b, make it fix at ultimate extension length to realize the extension of whole barrel, be convenient for to the spraying operation under the specific condition. Because the inner tube 2 and the sleeve 3 are both rectangular sections, the telescopic structure of the inner tube 2 and the sleeve 3 cannot shake too much when the matching size is within a reasonable range.
When the sheet metal component of spraying need follow certain track and carry out the spraying, can use positioning table 6, press the sucking disc that adsorbs on positioning table 6 lower clutch 9 all around and can confirm the track all around processing the track. When confirming well processing the track, press deformation button 10b and warp the barrel, need to go into the U type inslot of positioning table 6 with a spacing ball 1a portion card on the rifle body 10 bending tube 1 this moment, along the groove inwards push can, because a spacing ball 1a under the effect of bottom spring deformation, when passing through U type groove width minimum point, will buckle pipe 1 and be fixed in U type groove. After the operation is finished, the gun body 10 is pulled out of the U-shaped groove along the path only when the gun body is withdrawn.
When the special-shaped inner corner surface is required to be sprayed along a track, the adsorption angle of the sucker can be adjusted only by rotating the upper joint 8 and the lower joint 9 at the bottom of the supporting leg 7, and the adsorption direction of the sucker can be adjusted by rotating the upper joint 8 along the horizontal direction. The matching among the supporting legs 7, the upper joint 8 and the lower joint 9 completes the dead-angle-free spraying of the fixed area at the special-shaped inner angle.
