Abstract

The utility model relates to a spraying cup for static powder spraying gun. The spraying gun is provided with an outlet; a main shaft is arranged in the outlet in the mode of rotation in-situ; the spraying cup is arranged on the outlet part of the spraying gun through the main shaft; the spraying cup comprises a pipe body connected and arranged on one end of the main shaft; a turbine is arranged in the pipe body; the turbine is provided with a plurality of radially arranged blades; the blade surface of each blade is inclined to the same direction; when connected with the main shaft in the spraying gun, the spraying cup can be driven to rotate at a high speed by the main shaft; when passing through the pipe body of the spraying cup, the paint sprayed from the spraying gun can collide with the surfaces of the blades and generate the atomization; the paint can be sprayed outwards in radial patterns under the impact force of the rotation of the spraying cup; the paint can be atomized into thinner molecules; thus, the adhesive force of the paint adhered to the surface of the work piece can be improved, and the painting surface can be more uniform.

Description

The spray cup of powder electrostatic spray gun

Technical field

The utility model is relevant with application machinery, is meant a kind of spray cup of powder electrostatic spray gun especially.

Background technology

Known powder electrostatic spray gun is to utilize pressure-air ejection coating, connects the diffuser plate that is located on the spray gun by one again, makes to strike the surface of diffuser plate earlier when coating outwards sprays and atomize, and outwards sends forth radially.

Yet, known powder electrostatic spray gun is in the mode of diffuser plate atomised coating, it is not enough that its fogging degree is still disliked, make the coating deposit efficiency not good, therefore, coating flows because of the gravity relation produces easily, causes below, application zone coating comparatively thick and heavy, and the comparatively rare situation of top coating, part in fact haves much room for improvement.

Summary of the invention

At the problems referred to above, main purpose of the present utility model is to provide a kind of spray cup of powder electrostatic spray gun, and it can make the coating atomizing of spray gun ejection be more tiny molecule, and then improves the coating deposit efficiency, makes workpiece can obtain more uniform processing surface.

For achieving the above object, the spray cup of a kind of powder electrostatic spray gun provided by the utility model, spray gun has an outlet, but the mode with the original place rotation in it is provided with a main shaft, spray cup is installed in the exit of spray gun by main shaft, and the spray cup comprises a body, connects and is located at main shaft one end; One is arranged at the turbine in the body, and turbine has the blade of plural radial arrangement, and the blade face of each blade tilts in the same direction.

Adopt technique scheme, when spray cup of the present utility model and main shaft in the spray gun connect establish after, can be driven by main shaft and rotation at a high speed, make from the coating of spray gun ejaculation, when the body of process spray cup, atomize because of the surface collision with blade produces, and outwards send forth open radially with the impulsive force of spray cup rotation, make coating be atomized into more tiny molecule, and then improve adhesive force, make the application surface more even attached to the work package surface.

The specific embodiment

As shown in Figure 1 and Figure 2, the application schematic diagram that combines with a powder electrostatic spray gun 20 of the spray cup 10 that is provided for the utility model preferred embodiment.Spray gun 20 has an outlet 21, but is provided with the main shaft (not shown) of an original place rotation in it, and coating sent main shaft by pressure-air, from exporting 21 ejections, because spray gun 20 is a prior art, does not repeat them here again.Spray cup 10 of the present utility model includes: a conical tube 11 and is located at the turbine 12 in the body 11, wherein:

Body 11 is a conical tube, has a bigger diameter end 111 and a miner diameter end 112, and in the present embodiment, miner diameter end 112 screws togather with the mode that is spirally connected and an end of main shaft, for coating by its pipe shaft.

Turbine 12 is made up of the blade 121 that plural pieces is inclination, and each blade 121 arranges radially, and an end is connected with each other, the other end then links with the internal face of body 11 respectively, in addition, the blade face of each blade 121 tilts in the same direction, and the angle of body 11 axles is between 45 degree are spent to 89.

Adopt said structure, the advantage of spray cup provided by the utility model is: for the mode of in the past utilizing the diffuser plate atomizing merely, spray cup provided by the utility model is because of being driven rotation at a high speed by main shaft, when coating passes through the blade 121 of spray cup turbine 12, just can be because of producing collision with blade 121 surfaces, add the relation of revolving force effect, and atomizing is for more tiny molecule, is thrown out of radially subsequently and is attached to the work package surface.Because the tiny factor of coating molecule makes therefore to be difficult for the adhesive force lifting can obtaining finished surface more equably because of the gravity relation causes the thick situation that approaches that goes up under the application zone.

Certainly, the utility model also can be installed diffuser plate, as shown in Figure 3, be second preferred embodiment of the present utility model, turbine 31 center back of spray cup 30 are extended a protuberance 311, make turbine 31 can be arranged with an embedding hole 312 from its front end center, make on the spray gun (among the figure shown in the imaginary line) and also can install a diffuser plate 40 additional, diffuser plate 40 has an interlocking bar 41, it can connect with the embedding hole 312 of turbine 31 and establish, to utilize diffuser plate 40, allow the user can select the coating fogging degree and the spraying effect of spray gun as required again with the coating atomizing.

Again as shown in Figure 4, be the spray cup 50 of the utility model the 3rd preferred embodiment, the embedding hole 51 of spray cup 50 also can combine with a spray point 52, and the carried charge with the application powder strengthening passing through promotes powder adhesive force.Because spray point is a prior art, therefore repeat no more.

What must remark additionally is, spray cup of the present utility model, and the axle angle of the blade face of its blade and its body is when 45 degree are between 89 spend, and the atomizing effect of coating is best.Certainly, also can adjust by the needs appropriateness of actual design.Therefore, this extraneous variable inclination degreeization of inclining must be included in the protection domain of the present utility model.
