The specific embodiment
See also Fig. 1 and Fig. 2, the ejecting device 10 that first embodiment of the invention provides comprises one first shower nozzle 12 and one second shower nozzle 14.
This first shower nozzle 12 and these second shower nozzle, 14 shapes are basic identical, all elongated, and the cross section be rescinded angle vertebra shape and rectangle in conjunction with shape.The length of this first shower nozzle 12 and this second shower nozzle 14 can be decided as required.This first shower nozzle 12 and this second shower nozzle 14 be arranged in parallel side by side.This first shower nozzle 12 comprises upper surface 120 and side 121, and this second shower nozzle 14 comprises upper surface 140 and side 141.First shower nozzle 12 comprises at least one feeding mouth and at least one discharging opening.Second shower nozzle 14 comprises at least one air intake and at least one gas outlet.
In the present embodiment, this first shower nozzle 12 comprises a plurality of circular hole feeding mouths 20 and 1 discharging opening 21 that all is communicated with these a plurality of feeding mouths 20.This feeding mouth 20 can be arranged on the upper surface 120 of first shower nozzle 12, also can be arranged on the side 121 of first shower nozzle 12.These a plurality of feeding mouths 20 are arranged in delegation along the length direction of this first shower nozzle 12.Feeding mouth 20 is connected with quantitative discharging device (as shown in Figure 3).Material can be the higher material of colloidal form, especially viscosity, is mainly used in the formation film, for example forms the reflecting layer of thin-film solar cells etc.Discharging opening 21 is an elongated slot-like.In other embodiments, the circular hole discharging opening that be separated from each other corresponding with feeding mouth 20 quantity can be set.
This second shower nozzle 14 comprises that quantity is more than a plurality of circular hole air intakes 40 of feeding mouth 20 and a gas outlet 41 that is communicated with these a plurality of air intakes 40.Air intake 40 can be arranged on the upper surface 140 or the side 141 of first shower nozzle 12.Gas outlet 41 is elongated slot-like.In other embodiments, a plurality of circular hole gas outlet that be separated from each other corresponding with air intake 40 quantity can be set.The pressure of the air-flow of these second shower nozzle, 14 ejections equates everywhere.These a plurality of air intakes 40 are arranged in delegation along the length direction of this second shower nozzle 14, and 5 air intakes 40 wherein align with 5 feeding mouths 20.
More even for the air pressure of the air-flow that makes the ejection of second shower nozzle 14, an equal splenium 412 (referring to Fig. 3) can be set in the inside of air intake 40.All splenium 412 can be a mushy material, for example, and dustless cloth, sponge etc.Mushy material is placed on the position of air intake 40 inner portions, and when gas is divided into the multiply air-flow during through mushy material, speed descends, and form one etc. pressure gas stream 41 flow out from the gas outlet, and the direction of air-flow will be basically perpendicular to base material.
When base material (referring to Fig. 3) plane, place is vertical with the material flow outgoing direction, it is inhomogeneous when the material that discharging opening 21 is gone out drops on base material, for example central part thickness is thicker, side is thinner, therefore make equal pressure gas stream direction and the aligning central part substantially parallel of gas outlet 41 ejections with the falling direction of this material, thereby make the material at thicker position spread to thin district, the suffered air pressure of each part was tending towards equal when the thickness convergence in the material entire scope was consistent, thereby material is no longer mobile, can form homogeneous film.
In the present embodiment, first shower nozzle 12 comprises 5 feeding mouths 20, and this second shower nozzle 14 comprises 13 air intakes 40.More air intake 40 can provide wider equal pressure gas stream.Allow in other embodiments, the quantity of feeding mouth 20 and air intake 40 is identical, the position is corresponding.The quantity of feeding mouth and air intake and position depend primarily on the viscosity and the parameters such as flowability, flow parameter and coating speed of material.
The shape of the shape of the gas outlet 41 of this second shower nozzle 14 and the discharging opening 21 of this first shower nozzle 12 is consistent can be blown out the uniform film of a thickness by the air-flow of this second shower nozzle 14 so that the material that flowed out of this first shower nozzle 12 is easier certainly.This first shower nozzle 12 and second shower nozzle 14 can be to make respectively, fit together then, and also can be one-body molded, promptly directly on a mould, two exhausting holes are set, and make the usefulness of material spray and the usefulness of air blowing respectively.This first shower nozzle 12 and this second shower nozzle 14 also can independently be provided with, and do not fit together.
Can expand first shower nozzle 12 and second shower nozzle 14 according to actual conditions, promptly the side relative with first shower nozzle 12 at second shower nozzle 14 continues to add one first shower nozzle and one second shower nozzle, like this can be disposable base material in be in a big way carried out material spray and air blowing.
See also Fig. 3, the coating system 50 that second embodiment of the invention provides comprises drawing mechanism 51, pulsometer 52, ejecting device 10, conveyer 53.Ejecting device 10 comprises first shower nozzle 12 and second shower nozzle 14.Conveyer 53 comprises one first roller 531 and second roller 532, is used for carrying and transmits base material 54.Base material 54 can be selected flexible material for use.Certainly, also can on hard substrate, spray material and blow the even film that forms then.
The feeding mouth 20 of the drawing mechanism 51 and first shower nozzle 12 communicates, and makes material to flow out from the discharging opening 21 of first shower nozzle 12.In the present embodiment, a drawing mechanism 51 communicates with a feeding mouth 20; In other embodiments, a plurality of pipelines are set can for drawing mechanism 51, each pipeline communicates with a feeding mouth 20.The air intake 40 of the pulsometer 52 and second shower nozzle 14 communicates, and makes that gas can evenly ejection from the gas outlet 41 of second shower nozzle 14.In the present embodiment, a pulsometer 52 communicates with an air intake 40; In other embodiments, a plurality of pipelines are set can for pulsometer 52, each pipeline communicates with an air intake 40.
When first shower nozzle 12 with material 55 stream after base material 54, base material 54 moves to second shower nozzle, 14 belows, perhaps ejecting device 10 moves and makes the gas outlet of second shower nozzle 14 aim at material 55, thereby blows material 55 even.Blowing the even time to determine by calculating.For example, certain for each load, the situation that air velocity is certain is obtained the average time of blowing even material, then, will be decided to be the standard time operation of blowing this average time.
Mobile dependence first roller 531 of base material 54 and the scrolling realization of second roller 532.Certainly, also can adopt other kind of drive.The direction of arrow is represented the moving direction of base material 54 among the figure.In the present embodiment, base material 54 is vertical with the material spray direction and the jet direction of first shower nozzle 12 and second shower nozzle 14 all the time in moving process.
The coating system 50 of ejecting device 10 provided by the invention and this ejecting device 10 of employing can be implemented in the even painting process in the continuous process, and is simple in structure, realizes easily.
Be understandable that those skilled in the art also can do other variation in spirit of the present invention, all should be included within the present invention's scope required for protection.
