Description
Technical field
The utility model relates to a kind of nozzle, relates in particular to a kind of adjustable coating of masking liquid quantity for spray precoating nozzle of using with the steel coating machine.
Background technology
Used a kind of precoating nozzle that the band steel is carried out precoating, this precoating nozzle comprises as shown in Figure 1: feed liquid pipeline 1 in the past; Form one with this feed liquid pipeline 1 outer wall, have spray orifice 2a and be communicated with the endoporus 1a of feed liquid pipeline 1 and a plurality of masking liquid ejiction opening 2b, the 2b of the predetermined distance of being separated by ... cuboid nozzle head 2; Be installed in the bristle 3,3 on the nozzle head 2; And protuberance 4a is entrenched in the spray orifice 2a and flange 4b is inserted in the slot 2c of nozzle head 2 and the spray volume adjusting device 4 of the convex shape that slidably moves.Spray volume adjusting device 4 is a convex shape by the polyethylene one-shot forming.
The operation principle of the precoating nozzle of this structure is, band steel insulating coating solution is delivered to the masking liquid ejiction opening 2b of precoating nozzle by feed liquid pipeline 1, after masking liquid ejiction opening 2b ejection, coat the surface (gap location of redundant coating liquid between spray volume adjusting device 4 and nozzle head 2 is left to the not shown batea) of band steel G, make the whole plate face of band steel that masking liquid all be arranged, essence through coating roller is coated with again, make the masking liquid that is distributed with uniform film thickness on the belt steel surface, behind the overbaking sintering, be solidificated in belt steel surface then and form dielectric film.When the strip width position after changing on the precoating nozzle, need manually spray volume adjusting device 4 to be carried out the width adjustment, produce the phenomenon of edge thickening or cause the masking liquid spray less than being with the phenomenon that produces the coating inequality on the steel because of adjustment amount is too small to prevent that the masking liquid ejection from turning over too much at band steel another side.But, the whole bottom of convex shape spray volume adjusting device 4 is the closed structure on plane, after spray volume adjusting device 4 is inserted in the slot 2c of nozzle head 2, it protrudes end face 4c and is lower than the bristle 3 that is installed on the nozzle head 2,3 the about 4mm of bristle end face 3a (with reference to Fig. 1 (b)), after the nozzle head ejection of masking liquid by the precoating nozzle, redundant coating liquid can be from the gap location ejection of 4mm, turn on owing to touch that the motion that produces surface tension and strip edge portion behind the band steel G causes taking up masking liquid, thus on band steel G the bad phenomenon (as shown in Figure 1) of generation edge thickening and coating inequality.
The utility model content
Problem in view of above-mentioned existence, the purpose of this utility model is to provide a kind of like this coating precoating nozzle, can adjust the width of masking liquid ejection, function with sealing masking liquid, water conservancy diversion masking liquid, can prevent from again to translate on the masking liquid to be coated with on the object, eliminate the phenomenon that is coated with object edge thickening and coating inequality.
For achieving the above object, coating of the present utility model comprises with the precoating nozzle: feed liquid pipeline (1); Form one with described feed liquid pipeline outer wall, have spray orifice (2a) and be communicated with the endoporus (1a) of described feed liquid pipeline and a plurality of masking liquid ejiction opening (2b, the 2b of the predetermined distance of being separated by ...) cuboid nozzle head (2); Be installed in the bristle (3,3) on the described nozzle head; And protuberance (4a) is entrenched in the described spray orifice and flange (4b) is inserted in the slot (2c) of described nozzle head and the spray volume adjusting device (4) of the convex shape that slidably moves, wherein, form the recess (4k) of undercut shape in the bottom of described spray volume adjusting device central authorities, on the protrusion end face (4c) of described spray volume adjusting device, be fixed with spray volume adjusting device bristle (5).
In addition, to be installed in the described bristle upper surface on the described nozzle head apart be 0.5～1.5mm in the upper surface of described spray volume adjusting device bristle.
In addition, the shape of cross section of described recess is rectangle or semicircle.
In addition, the length of described spray volume adjusting device is the length of sealing described a plurality of masking liquid ejiction openings at least.
And a side that is preferably in described spray volume adjusting device is provided with and pulls bar (6).
Adopt coating of the present utility model precoating nozzle, not only can adjust, and masking liquid can be coated on equably and be coated with object and promptly be with on the steel, can not produce the phenomenon that masking liquid thickens in strip edge portion the width of masking liquid ejection.

The specific embodiment
Below, describe coating of the present utility model precoating structure of nozzle and beneficial effect in conjunction with the accompanying drawings in detail.
Shown in Fig. 2 (a) and (b), coating of the present utility model comprises with the precoating nozzle: feed liquid pipeline 1; Form one with this feed liquid pipeline 1 outer wall, have spray orifice 2a and be communicated with the endoporus 1a of feed liquid pipeline 1 and a plurality of masking liquid ejiction opening 2b, the 2b of the predetermined distance of being separated by ... the cuboid nozzle head 2 of (present embodiment is shown as 4 masking liquid ejiction openings, also can be made as 2 or the masking liquid ejiction opening more than 3 even 5 according to the length of feed liquid pipeline 1); Be installed in the bristle 3,3 on the nozzle head 2; And protuberance 4a is entrenched in the spray orifice 2a and flange 4b is inserted in the slot 2c of nozzle head 2 and the spray volume adjusting device 4 of the convex shape that slidably moves.Wherein, form the recess 4k of undercut shape in the bottom of spray volume adjusting device 4 central authorities, and the shape of cross section of this recess is set as rectangle (shown in Fig. 2 (a)), also can be set as semicircle (not shown), in addition, on the protrusion end face 4c of spray volume adjusting device 4, be fixed with spray volume adjusting device bristle 5.
The length of spray volume adjusting device 4 is to seal present embodiment not 4 masking liquid ejiction opening 2b, 2b at least ... length.
In addition, preferably spray volume adjusting device bristle 5 is set as the upper surface that its upper surface is installed in the bristle 3 on the nozzle head 2 apart and is about 0.5～1.5mm, in the present embodiment, be made as 1mm (shown in Fig. 2 (b)).
And as shown in Figure 3, a side that is preferably in spray volume adjusting device 4 is provided with and pulls bar 6, is used to control the spray volume of precoating nozzle.
By making structure as described above, for example be with steel (silicon steel) when G etc. in advance spray with the precoating nozzle to being coated with object with coating, spray volume adjusting device 4 is inserted in the precoating nozzle, hold and pull bar 6 lateral adjustments width positions, make the ejection of band steel G marginal position masking liquid, after the masking liquid ejiction opening 2b ejection of masking liquid by the precoating nozzle, redundant coating liquid can be discharged from the undercut shape recess 4k of spray volume adjusting device 4 bottom central authorities, because spray volume adjusting device 4 itself also is fixed with bristle 5, and be installed in bristle 3 on the nozzle head 2 at a distance of for about 1mm, therefore, can effectively prevent masking liquid from translating into from the gap location between spray volume adjusting device 4 and the nozzle head 2 on the band steel, thicken phenomenon with the coating inequality thereby eliminate strip edge portion.If there is strip width to change, regulate spray volume adjusting device 4 this moment again in the lateral attitude, guarantees that the masking liquid ejection is normal.
This coating is simple with the precoating nozzle arrangements, and cost of manufacture is low, and is easy to operate, can guarantee coating quality.This precoating nozzle can be used in the silicon steel coating machine system, also can be used for other masking liquids more liquid, have in the coat system of precoating function.
