Background technology
Such spray gun is known by EP0706832B1.It has the compressed air distributor being connected on blowpipe, and the compressed air of blowpipe is distributed on loudspeaker air-flow feeding pipe (Hornluftversorgungsleitung) and circular jet feeding pipe (Rundstrahlversorgungsleitung).The air supply that can flow to by the bolt regulating part setting of regulating cock valve loudspeaker air-flow feeding pipe, this plug valve has the little sealing-plug being positioned on end, for opening or closing continuously loudspeaker air-flow feeding pipe.Pressure in the situation that closing loudspeaker air-flow in circular jet region raises while exceeding the peak of spray gun permission, for the pressure occurring in circular jet region being limited to certain maximum, this plug valve is from its end, have at little sealing-plug rear the region that diameter is larger, the air path between compressed air conveying pipeline and circular jet feeding pipe is also shunk continuously in this region in the time closing loudspeaker air-flow feeding pipe.Plug valve is offset in the axial direction by rotatable knurled knob there.The solution of describing in that patent has following shortcoming,, is used to open or close the pipeline in compressed air distributor and adjustment movement in the axial direction based on plug valve that is, exceedes one week so knurled knob must rotate.And because plug valve design has the disk body of little sealing-plug and chip, so can only inaccurately determine in advance or calculate the air distribution in compressed air distributor.In addition, the manifold make in that patent is disadvantageous for manufacturing process.In addition, in the time regulating, the spacing between knurled knob and rifle body changes, and this is often considered to shortcoming.
By known a kind of spray gun and a kind of compressed air distributor in DE102009032399A1, it can overcome above-mentioned various shortcomings, and make it possible to realize the setting of pressure is carried out to shirtsleeve operation, and the compressed air that can calculate like a cork in spray gun distributes.
Known spray gun is characterised in that thus, regulating part is designed to cannot move in the axial direction of rotation and remains on compressed air distributor in compressed air distributor chamber and that can rotate around this rotation, be used to open or close the geat of circular jet pipeline and flat jet pipeline.Because only adjustment movement diametrically of compressed air distributor, can realize obviously less, flat jet opening here from being closed to the adjusting angle of opening completely completely.According in the solution of EP0706832B1, this adjusting angle relatively but reaches about 410 °, so the knurled knob in that patent must rotate and exceed a whole circle in the time that loudspeaker gas flow opening is closed from being opened to.This has also hindered the current aperture position that shows simply loudspeaker gas flow opening.Can relatively simply simulate in addition, calculate or according to empirically determining the design of compressed air distributor, and therefore relatively simply simulate, calculate or according to empirically determining the setting to the correct proportions between the different geat in compressed air distributor chamber.Another advantage is always to have identical spacing with rifle body for the revolving part of compressed air distributor.

Distributor screw rod 13 and therefore also have compressed air distributor 14 can both distribute the revolving part that is designed to knurled knob 15 in cylinder 8 to rotate around rotation D diametrically by compressed air.Knurled knob 15 can be from the position shown in Fig. 2 a (now flat jet pipeline geat 7' opens) pass through in the clockwise direction the position shown in Fig. 4 a (now flat jet pipeline geat 7' partially opens) and rotate to the position shown in Fig. 6 a (now flat jet pipeline geat 7' closes).Make thus the pressure supply of the flat jet nozzle 5 in the tubaeform portion of pigment shower nozzle 3 be reduced to continuously stress-free state.Prevent that by stopper section 21 knurled knob 15 from turning over the position shown in Fig. 6 a in the clockwise direction, or turn in the counterclockwise direction the position shown in Fig. 2 a, these stopper sections form an entirety with gun body 1 in the present embodiment and (see Fig. 2 d, 4d, 6d and 2e, 4e and 6e).Guarantee thus particularly can not continue rotation in the clockwise direction and again compressed air is imported in flat jet pipeline 7 because careless in the case of the flat jet pipeline geat 7' shown in Fig. 6 a closes completely, and minimum in circular jet pipeline 6 or reduce after air capacity can not increase or continue minimizing.
At this, knurled knob 15 always keeps identical distance with rifle body 1.Select as follows this distance at this, that is, make material spray (Overspray) or the analog of transition cannot immerse distributor screw rod 13.In an embodiment, this distance is approximately 1.2mm.Therefore, there is very high safety in operation according to design of the present utility model.Avoided in addition because revolving part erect too high and bring constant.
In Fig. 2 c, can find out the region of spray gun 1, the compressed air of wherein having introduced cylindrical hole form distributes cylinder 8.The bottom 8a in hole is smooth, and substantially distributes with compressed air the angle that the case surface 8b shape of cylinder 8 is in 90 °.Bottom 8a and case surface 8b form the wall that compressed air distributes cylinder 8.From Fig. 2 c, can find out the hole of blowpipe 10, and circular jet pipeline 6 and flat jet pipeline 7 pass in compressed air distribution cylinder 8 with the staggered 90 ° of ground substantially of blowpipe 10 in the peripheral direction of compressed air distribution cylinder 8.This compressed air distributor 14 can distribute the opening 8c of cylinder 8 to insert wherein from compressed air.
The distributor screw rod 13 of compressed air distributor plug-in unit 14 has circular shrouding disc 17, and this shrouding disc makes compressed air distribute the interior chamber of cylinder 8 further to seal to outside.This shrouding disc distributes the rotation guiding device of the compressed air distributor 14 in cylinder 8 as compressed air.Shrouding disc 17 is applicable to the interior diameter that compressed air distributes cylinder 8, makes it possible to carry out central rotation accurately, and there is no large gap.
In the present embodiment, compressed air distributor plug-in unit 140 is designed to Liang Ge branch.Be made of metal at the distributor screw rod 13 shown in Fig. 7, made by brass.Guarantee thus extra high material solidness and guiding accurately.Compressed air distributor 14 is made of plastics, and is made up of polyamide.The width dimensions of this compressed air distributor slightly more greatly, make its after inserting in spray gun 1 by extruding a little.Guarantee thus to seal up well guiding piece.In addition,, although the version more complicated of this compressed air distributor, because the material providing is selected and corresponding design, it can be smoothly through spray to cast method and make.Due to selected combination of materials, also the production cost of compressed air distributor plug-in unit 140 can be remained in desirable boundary accordingly.
But, can certainly be with any another metal or another plastics or with other arbitrarily combination of materials one or many parts ground manufacture compressed air distributor plug-in unit arbitrarily.
End thereon, distributor screw rod 13 rotatably remains on compressed air by threaded sleeve 18 and distributes in cylinder 8, although compressed air distributor plug-in unit 140 is distributed in cylinder 8 at compressed air can be round rotation D rotation, can not distribute passing in axial direction of the rotation D in cylinder 8 at compressed air.For this reason, threaded sleeve 18 is screwed to compressed air by external thread rotary and distributes in the corresponding internal thread on the outer end of cylinder 8.The circular annular region that deviates from compressed air distributor 14 of shrouding disc 17 is used the stopper section of the end face towards compressed air distribution cylinder 8 that acts on threaded sleeve 18.Therefore, threaded sleeve 18 is responsible for the secure localization of distributor screw rod 13, and be therefore responsible for compressed air distributor 14 and distribute the location in cylinder 8 at compressed air, and except shrouding disc 17, concur with being designed to annular seal 23 here the interior chamber that seal compression air distributes cylinder 8, stop air to external leakage.
Extraly also with respect to rifle body 1 sealing thread sleeve pipe 18.
Knurled knob 15 is torsionally by being connected with distributor screw rod 13 at the screw bolt 19 shown in Fig. 2 c.For this reason, screw bolt 19 is engaged in threaded cephalic par of joining of compressed air distributor plug-in unit 140.By the interior axle collar 24 on knurled knob 15, at the pre-tensioner seal 23 when threaded together bolt 19 in order to manufacture reliable sealing effectiveness.
The interior axle collar 24 on knurled knob 15 concurs with the stopper section 21 on rifle body 1.In the present embodiment, on open position and closed position, be respectively arranged with a stopper section 21.These two positions form the angle of 95 degree in the present embodiment.Can visually aware well thus the adjusting of position.
In the admissible embodiment of another kind, can design larger angle, for example, between 90 ° and 180 °, be still preferably always less than 360 °.
As can finding out in Fig. 2 a, knurled knob 15 has the position indication piece 20 of cut forms, it vertically points in the time that flat jet pipeline geat 7' opens completely as shown in Fig. 2 a-2e, and in the time that flat jet pipeline geat 7' closes completely, rotate in the clockwise direction about 95 ° in the indication piece of locational position shown in Fig. 6 a 20.
Instead, also can design example except otch if the single mark of impression or scale are as position indication piece 20.Can certainly position indication piece 20 not designed on knurled knob 15, and design is on rifle body 1.
In the variant of the knurled knob 15 shown in Fig. 7, position indication piece is designed to be molded in position mark 28 on knurled knob 15, projection.In the present embodiment, it is long especially that this position mark 28 designs, and on the whole surface of imaginary diameter line side extend through knurled knob 15; Except the zone line of knurled knob, this region is made up of bolt 19.On unshowned rifle body, can be provided with position mark that mate with position mark 28, projection here.In this variant, can visually aware particularly well the adjusting of position.
In the present embodiment, distributor screw rod 13 and compressed air distributor 14 form compressed air distributor plug-in unit 140.It is for example made up of adapter ring, hex bolts and sealing ring 23 connected system 150() be connected with knurled knob 15 by bolt 19.Can certainly realize and connecting with other form, for example, connect by socket connection or clamping, or connect by bayonet socket.Putting in order of member also can change, thus for example sealing ring 23 can be placed on another position, or can be provided with multiple sealing rings.
Set forth now the structure of compressed air distributor 14 by Fig. 8.It illustrates the embodiment from a kind of compressed air distributor 14 of Fig. 7.The flat jet that flat jet control band 146 has for closing circular jet pipeline geat 7' completely closes closed region 146a, and for opening continuously or close the flat jet open area 146b of flat jet pipeline geat 7'.
In contrast to this, circular jet control band 147 is positioned at top and the close shrouding disc 17 of flat jet control band 146, and this is because circular jet pipeline 6 passes into the upper area that compressed air distributes cylinder 8.Shrouding disc 17 in Fig. 8 is incomplete, and this is because it is constructed and form together by unshowned distributor screw rod 13 in Fig. 8 in the present embodiment.Because circular jet pipeline opening 6' also slightly misplaces with respect to flat jet pipeline opening 7' in the circumferential direction of compressed air distribution cylinder 8, so circular jet control band 147 correspondingly misplaces with respect to flat jet control band 146 in addition in circumferential direction.This circular jet control band 147 has the circular jet that is almost in the present embodiment rectangle opening 147a is set, it closes closed region 146a dislocation with respect to flat jet like this,, close completely and when blowpipe 10 opens completely simultaneously, can not exceed in circular jet pipeline 6 and the maximum pressure therefore allowing on circular jet nozzle 4 at flat jet pipeline 7.
Self-evidently, circular jet arranges opening 147a and also can be designed to slotted hole, trapezoidal, hexagon, octagonal or similar shape.
Right hand edge, the circular jet of compressed air distributor 14 in Fig. 8 arranges opening 147a and also has flat jet to close closed region 146a formation blowpipe control band, and structure forms as follows,, when compressed air distributor 14 is during in position shown in Fig. 6 a-6e, blowpipe geat 10' fully distributes cylinder 8 to open towards compressed air, and any member of just mentioning of not compressed air distributor 14 hides.
But with under the state shown in Fig. 2 a-2e on the contrary, not only flat jet closes closed region 146a, also have the right hand edge of circular jet control band 147 in Fig. 8 and the short region 148 between them can reach in blowpipe geat 10' always, in the time that circular jet pipeline geat 6' and flat jet pipeline geat 7' open completely, in circular jet pipeline 6 or flat jet pipeline 7, leading maximum pressure is no more than the maximum pressure of permission.
Fig. 1 a-1d and Fig. 2 a-2e illustrate the position of compressed air distributor 14 in the time that circular jet pipeline geat 6' and flat jet pipeline geat 7' open completely, that is to say the position there is maximum pressure on circular jet nozzle 4 and flat jet nozzle 5 time.At this moment, compressed air distributor 14 is opened circular jet pipeline geat 6' and the flat jet pipeline geat 7' in compressed air distribution cylinder 8 completely at this.Blowpipe geat 10' is the but blowpipe control band of compressed air distributor 14 covering substantially on the contrary, thereby distributes the pressure in cylinder 8 to be limited on the maximum pressure of permission compressed air.
Carry compressed air in order to reduce to flat jet nozzle 5, and therefore reduce to be that compressed air distributes the pressure on the flat jet pipeline geat 7' in cylinder 8, knurled knob 15 is rotated to about 45 ° in the clockwise direction from the position shown in Fig. 2 a and enter the position shown in Fig. 4 a.This can directly find out for user on position indication piece 20.Thus by the flat jet pipeline geat 7' of flat jet open area 146b rotation process of the flat jet control band 146 shown in Fig. 8.Meanwhile, 147 rotations of circular jet control band are through circular jet pipeline geat 6', and it is partly hidden at the edge, lower-left shown in Fig. 8 by circular jet control band 147 thus, and partly by circular jet, opening 147a unlatching is set.Meanwhile, open continuously blowpipe geat 10' by rotary compression air distributor 14, but on the position shown in Fig. 4 a-4e as before still partly keep compressed air distributor 14 to hide.Because circular jet pipeline geat 6' and flat jet pipeline geat 7' diminish simultaneously, but but increase by the compressed air of blowpipe geat 10' input, so being set as follows, compressed air distributes the pressure dependence in cylinder 8,, be no more than and be connected on circular jet pipeline 6 also have maximum pressure on flat jet pipeline 7 and that be allowed in them.
If then by knurled knob 15 and therefore compressed air distributor 14 is continued in the clockwise direction rotation about 45 °, forward the position shown in Fig. 6 a to from the position shown in Fig. 4 a, arrive the position that flat jet pipeline geat 7' is fully closed.As can be from can finding out Fig. 6 c and Fig. 6 b, at circular jet pipeline geat 6', opening 147a being also set by a part of circular jet loads from the blowpipe geat 10'(Fig. 6 c to e opening completely at that time) compressed air during, flat jet pipeline geat 7' closes completely.By compression distributor 14 and its special shape, it is flat jet open area 146b, circular jet open area 147a, circular jet control band 147 and extension blowpipe control band of adjacency with it, guarantee in the whole closing process of flat jet pipeline geat 7', no matter be on circular jet pipeline 6 and wherein or on flat jet pipeline 7 and wherein, and therefore on attached troops to a unit nozzle (circular jet nozzle 4 and flat jet nozzle 5) can not reach the pressure that exceedes predetermined maximum pressure.
Instead, if correspondingly select circular jet that the geometric shape of opening 147a is set, so just can close circular jet pipeline geat 6' completely.
In addition,, according to the shape of flat jet open area 146b, can realize or be closing characteristics that power exponent changes or linear or that successively decrease.
In the present embodiment, flat jet open area 146b has circular opening 149, and it separates with the outward flange of compressed air distributor 14 by dividing plate 152.Increase the stability of compressed air distributor 14 by dividing plate.In addition, be used for manufacturing the material of compressed air distributor 14, for example plastics, so do not concentrate in the interior zone of member to heavens.Reduced thus the distortion that conventionally can produce in the time of cooling spray to cast parts.Dividing plate 152 has inclined plane 151, and it more easily flows through air from dividing plate 152.
In the embodiment of describing before compressed air distributor 14, the geat 10' of blowpipe 10 also can close, and reason is that the structure of compressed air distributor 14 structurally as one man mates the surface of blowpipe 10 as described previously.So, not carrying out in the alternate embodiments of this coupling, therefore just can not or closes compression air delivery pipe 10 fully.But, needn't worry can cause larger adverse effect to the ideal functionality of spray gun at this.Always there is following possibility, that is, optionally by all air total amounts or the air capacity of minimizing is flowed to compressed air distributor.
A significant advantage with respect to the solution commonly known in the art from other is, in the utility model, due to compressed air distributor 14 adjustment movement diametrically, can realize obviously much smaller adjusting angle.According in the solution of EP0706832B1, this adjusting angle is for example about 410 °, and knurled knob there is closed loudspeaker gas flow opening and just must be rotated and exceed whole one week from being opened to.This has also hindered the current aperture position that shows simply loudspeaker gas flow opening.In addition, utilize the plug valve with sealing-plug, EP0706832B1 is difficult to correctly arrange the proportionate relationship each other of different openings in compressed air distributor, and only in the situation that cost is very high, could correspondingly simulates or calculate.Adjustment movement can not be also here linear, and knurled knob can change the spacing of it and rifle body.If it is too high that knurled knob is erect, may allow the material spray of transition enter in spray gun, this just can not occur in solution described herein.
Another advantage is, successfully one-hand control compressed air distributor 14.
In the embodiment describing before, the opening 149 of flat jet open area 146b designs conglobate substantially.According to of the present utility model according to the embodiment of Fig. 9 in, opening be but relatively designed to triangle or drip shape 149a.Can produce favorable influence to the control curve of flat jet air according to opening leg-of-mutton or a shape of the present utility model, thereby particularly in so-called HVLP spray gun, realize accurate, recoverable spray figure setting.
In the embodiment shown in Figure 10, pressure distributor plug-in unit 140 is configured to an entirety, that is to say that distributor screw rod 13 and compressed air distributor 14 are unified in a member.Have the circular jet that is essentially rectangle that the embodiment of opening 147a is set is different from described above, the embodiment in Figure 10 has octagonal circular jet opening 147b is set.
Finally it is to be noted, described embodiment has only described limited several operational feasibilities that choose, and therefore the utility model is not formed to limitation.
