In the electrostatic spraying process, an electrostatic spinning cup spray gun is a core device for spraying. The existing electrostatic rotary cup spray gun has a large spraying area, and when some high-end ornaments need to be sprayed finely, the existing electrostatic rotary cup spray gun cannot spray the high-end ornaments accurately, so that the spraying requirements of the high-end ornaments cannot be met, and paint waste can be caused to a certain extent by large-area spraying.

To this end, referring to fig. 1 to 3, the present invention provides a nozzle structure of an electrostatic spinning cup spray gun, which is assembled with a body 2 of the electrostatic spinning cup spray gun. This shower nozzle structure includes: a head main body 1; the spray painting assembly is arranged in the spray head main body 1 and penetrates through one end, far away from the machine body 2, of the spray head main body 1; a plurality of fumarole 11, its outer wall of locating shower nozzle main part 1, when the assembly of shower nozzle structure and fuselage 2, fumarole 11 and the inside gas circuit intercommunication of fuselage 2, fumarole 11 is gaseous in order to gather the paint spray of the subassembly spun paint mist of spraying paint towards the direction blowout that is close to the subassembly spun paint mist of spraying paint.

The utility model discloses with shower nozzle and 2 assemblies of fuselage when using, the subassembly that sprays paint communicates paint pipe in order to acquire paint, and the air supply is put through in order to acquire the air current behind the gas circuit of 11 intercommunication fuselages 2 inside. After the static revolves cup spray gun and starts, the subassembly that sprays paint spraying spouts the coating cloud, and the fumarole 11 is gaseous towards the direction blowout coating cloud of subassembly blowout of spraying paint simultaneously to this effect of gathering together the coating cloud of subassembly blowout of spraying paint. Therefore, when some fine high-end ornaments are sprayed, the gathered paint mist can spray the ornaments more accurately; and the paint particles can be prevented from being sprayed outwards to cause waste in the spraying process, so that the utilization rate of the paint is improved.

In the present embodiment, the painting assembly includes: an impeller 12 fixed inside the head main body 1 and connected to the air passage; a rotor 13 fixedly connected to one end of the impeller 12 far away from the body 2; and a paint cup 14 disposed at one end of the rotor 13 away from the impeller 12, wherein an opening end of the paint cup 14 penetrates the nozzle body 1. Wherein, paint channels are arranged on the paint spraying rotary cup 14 and the rotor 13, and the paint channels are communicated with paint pipes. After the electrostatic bell cup spray gun is started, the gas drives the impeller 12 to rotate, thereby driving the rotor 13 and the paint cup 14 to rotate. When the paint is conveyed to the inner wall of the paint spraying rotary cup 14 rotating at a high speed, the paint is diffused into uniform fog drops along the inner wall of the rotary cup 14 under the action of centrifugal force and is sprayed out, and meanwhile, the paint is prevented from remaining on the surface of the spray head main body 1 to cause pollution.

In this embodiment, a plurality of gas injection holes 11 are evenly distributed around the open end of the paint bell cup 14. Therefore, when the paint spraying rotary cup 14 sprays paint mist, the gas sprayed from the air spray holes 11 can promote the paint mist to gather together from all directions, and meanwhile, the paint mist can be driven away from the spray head main body 1, so that paint residue is further avoided.

In the present embodiment, the opening direction of the gas ejection holes 11 is set in a direction close to the opening end of the paint cup 14. This allows the gas ejected through the gas ejection holes 11 to further gather the paint mist.

In the conventional electrostatic bell cup type spray gun, the paint bell cup 14 is mounted on the rotor 13, but since the open end of the paint bell cup 14 has a sharp edge and a small volume, the mounting process needs to be carefully performed. The utility model discloses in, the cup 14 is rotated in spraying paint and rotor 13 design for integrated into one piece, from this, has increased the volume of part, installs the operation better, has still saved the installation procedure.

In the present embodiment, the gas path includes a first gas path 21 and a second gas path 22, the impeller 12 is communicated with the first gas path 21, and the gas injection holes 11 are communicated with the second gas path 22. Therefore, when the paint mist does not need to be gathered, the second air passage 22 may not be connected to the air source, and the air injection holes 11 will not inject air.

In the present embodiment, the paint cup 14 is provided with a protrusion 141 toward the rotor 13, and the head body 1 is provided with a stopper 15 inside to restrict the movement of the protrusion 141.

In some examples, the stoppers 15 are respectively disposed on two sides of the protrusion 141 toward the paint cup 14 and the protrusion 141 toward the main body 2, so that the protrusion 141 can be restricted from moving in the two directions, that is, the movement of the cup 14 in the two directions is restricted, and the cup 14 is prevented from being separated from the preset position due to high-speed rotation.

The utility model discloses with shower nozzle and 2 assemblies of fuselage when using, the subassembly that sprays paint communicates paint pipe in order to acquire paint, and the air supply is put through in order to acquire the air current behind the gas circuit of 11 intercommunication fuselages 2 inside. After the static revolves cup spray gun and starts, the subassembly that sprays paint mist sprays, and the fumarole 11 is gaseous towards the direction blowout paint mist that is close to the subassembly that sprays paint mist simultaneously to this reaches the effect of gathering together the subassembly spun paint mist that sprays paint. Therefore, when some fine high-end ornaments are sprayed, the gathered paint mist can spray the ornaments more accurately; and the paint particles can be prevented from being sprayed outwards to cause waste in the spraying process, so that the utilization rate of the paint is improved, the loss is reduced, the production cost is reduced, and the market competitiveness of the product is improved.

While the present invention has been described in detail in connection with the drawings and the embodiments, it is to be understood that the above description is not intended to limit the present invention in any way. The present invention may be modified and varied as necessary by those skilled in the art without departing from the true spirit and scope of the invention, and all such modifications and variations are intended to be included within the scope of the invention.
