A kind of coating spray equipment
Technical field
The utility model relates to a kind of coating spray equipment, belongs to the coating technique field.
Background technology
Membrane material needs to apply the coating of special formulation in order to satisfy specific performance and requirement on the surface of film, generally adopt the intaglio plate applicator roll to be coated with.The surface engraving of intaglio plate applicator roll has the groove of definite shape and the degree of depth, and the roll surface groove is full of quantitative coating fluid, and film contacts with gravure roller surface, and the coating fluid in the gravure roll groove evenly is coated to the top layer that film surface forms specific function.
After coating fluid is coated to film surface, the residual coating fluid of gravure roll inside grooves contacts with air, solution is after volatilization, part solid constituent in coating fluid is separated out, remain in inside grooves, cause on the one hand gravure roll to be with the coating liquid measure to reduce, the coating liquid measure that is coated to the membrane material surface reduces thereupon, the reduction of coating stability; Coating fluid caking easily appears in the surface of gravure roll on the other hand, causes gravure roller surface groove and mesh to stop up, and occurs sticking with paste the roller phenomenon, and then coating is produced can't proceed.In order to eliminate this impact, need to clean gravure roll.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of coating spray equipment for cleaning the intaglio plate applicator roll.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of coating spray equipment, described device is comprised of liquid-feeding pump, control valve, metal shower, and liquid-feeding pump is connected with control valve by woven hose, and control valve is connected with the metal shower by woven hose, and metal shower surface distributed has spray apertures.
In above-mentioned spray equipment, the aperture of described spray apertures is 1 ~ 2 millimeter.
In above-mentioned spray equipment, the spacing of described spray apertures is 100 ~ 150 millimeters.
Compared with prior art, this apparatus structure is simple, reasonable in design, efficiently solve the solid constituent that causes due to the coating fluid solvent evaporates in the applicator roll groove and separate out problem, avoided sticking with paste the generation of roller phenomenon, stablized the coating quality of product, extended the coating time, improved film and be coated with online stability.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the relative position schematic diagram of the utility model device and intaglio plate applicator roll.
In figure, each list of reference numerals is: 1, intaglio plate applicator roll; 2, metal shower; 3, spray apertures; 4, control valve; 5, liquid-feeding pump; 6, woven hose.
The specific embodiment
When coating is produced, spray equipment is mounted to intaglio plate applicator roll 1 the place ahead, so that spray equipment can spray spray liquid the surface of intaglio plate applicator roll 1, make in the groove on intaglio plate applicator roll surface and keep moistening, reduce or avoid the surface of intaglio plate applicator roll 1 to stop up reticulate pattern groove and mesh because of caking, reducing and even avoided paste roller phenomenon.
Described spray equipment is comprised of liquid-feeding pump 5, control valve 4, metal shower 2, and wherein, liquid-feeding pump 5 is connected with control valve 4 by woven hose 6, and control valve 4 is connected with metal shower 2 by woven hose 6, and metal shower 2 surface distributed have spray apertures 3.During the coating beginning, open liquid-feeding pump 5, regulate the flow of spray liquid by control valve 4, spray liquid is delivered to the two ends of metal shower 2 by woven hose 3, and then being full of whole shower 2, spray liquid is ejected to the surface of intaglio plate applicator roll 1 from the spray apertures 3 on shower 2 surfaces.For the groove that makes intaglio plate applicator roll surface fully moistening, can be for different coating speeds, be arranged on the aperture of spray apertures on metal shower surface and the spray flux that spacing is adjusted spray liquid by adjustment.So continue spray, can prevent effectively that the surface of intaglio plate applicator roll 1 from stopping up reticulate pattern groove and mesh because of caking, reduce and even avoided paste roller phenomenon, stablized the coating quality of product, extended the coating time, improved film and be coated with online stability.
Liquid-feeding pump in spray equipment, control valve and woven hose can adopt known commercially available prod; The mixed solvent that the spray liquid that uses in spray equipment can use coating fluid or be deployed into according to the solvent that coating fluid uses preferably uses coating fluid.
The utility model is described in further detail below in conjunction with specific embodiment.
Embodiment 1
Spray equipment is arranged on the approximately place of 400 millimeters, intaglio plate applicator roll 1 the place ahead; It is that 1 millimeter, pitch of holes are the spray apertures of 100 millimeters that the surface distributed of metal shower 2 has the aperture.During the coating beginning, open liquid-feeding pump 5, regulate the flow of spray liquid by control valve 4, spray liquid is delivered to the two ends of metal shower 2 by woven hose 3, and then be full of whole shower 2, spray liquid is ejected to the surface of intaglio plate applicator roll 1 from the spray apertures 3 on shower 2 surfaces, make the groove on intaglio plate applicator roll surface fully moistening.
