Abstract
The utility model relates to a kind of high uniformity liquid cutter, it comprise corresponding closing lid two pieces of liquid knife plates, be formed at the first cavity between two pieces of described liquid knife plates, be formed at the fluid bar of two pieces of described liquid knife plate bottoms seam, the second cavity be connected with described first cavity is also formed between two pieces of described liquid knife plates, described second cavity stitches with described fluid bar and is connected, and the cross section of described second cavity is circular or oval.The utility model high uniformity liquid cutter, by arranging coupled the second logical cavity between fluid bar seam and the first cavity, and this second cavity is circular or oval, due to the existence of the first cavity and the second cavity, the particularly arcuate structure of the second cavity, fluid can be made to obtain sufficient pressure equalization within it, and the fluid ejected presents whole uniform waterfall.
Description
Technical field
The utility model relates to a kind of liquid cutter, relates to a kind of high uniformity liquid cutter particularly.
Background technology
At present, in the industries such as FPD industry, AMOLED industry, industry of printed circuit boards, photovoltaic industry, liquid cutter belongs to core component in whole processing procedure, particularly requires very high FPD and AMOLED industry, and the requirement of liquid cutter is high.
At present, liquid cutter major function is to eject from liquid cutter evenly, the waterfall of uniform thickness, and requires without bifurcated, without the even phenomenon of mass flow discrepancy.Observe according to the fluid analysis of traditional liquid cutter and practical application, the design of tradition liquid cutter, manufacture, be all that medium is tested with water, in actual applications, when tackling other liquid of different viscosities, liquid cutter cannot obtain reasonable jet graphics, make to occur spraying the problems such as uneven, injection jag.In order to address these problems, the solution of current routine is bar seam width or the expulsion pressure of adjustment liquid cutter, such adjustment makes liquid cutter jeting effect occur that some improve, but also there is some new problems simultaneously, as excessive in liquid cutter flow, the appearance of liquid cutter expulsion pressure these problems excessive must change the technique initialization of equipment end user, have impact on cleaning or etching effect, also result in certain cost waste.
Summary of the invention
The utility model object is to overcome the deficiencies in the prior art and a kind of high uniformity liquid cutter.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high uniformity liquid cutter, it comprise corresponding closing lid two pieces of liquid knife plates, be formed at the first cavity between two pieces of described liquid knife plates, be formed at the fluid bar of two pieces of described liquid knife plate bottoms seam, the second cavity be connected with described first cavity is also formed between two pieces of described liquid knife plates, described second cavity stitches with described fluid bar and is connected, and the cross section of described second cavity is circular or oval.
Optimally, the two ends of described fluid bar seam are provided with the pilot flow be connected with described second cavity, and the width of described pilot flow is greater than the width of described fluid bar seam.
Optimally, two pieces of described liquid knife plates are fixed by multiple screw.
Further, described screw is between described first cavity and described second cavity.
Optimally, the cross section of described first cavity is square, circular or oval.
Because technique scheme is used, the utility model compared with prior art has following advantages: the utility model high uniformity liquid cutter, by arranging coupled the second logical cavity between fluid bar seam and the first cavity, and this second cavity is circular or oval, due to the existence of the first cavity and the second cavity, the particularly arcuate structure of the second cavity, can make fluid obtain sufficient pressure equalization within it, and the fluid ejected presents whole uniform waterfall.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model high uniformity liquid knife structure schematic diagram;
Accompanying drawing 2 is the utility model high uniformity liquid cutter using state figure;
Wherein, 1, liquid knife plate; 2, screw; 3, the first cavity; 4, figure is sprayed; 5, the second cavity; 6, fluid bar seam; 61, pilot flow.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model preferred embodiment is described in detail:
High uniformity liquid cutter as depicted in figs. 1 and 2, mainly comprises liquid knife plate 1, first cavity 3, second cavity 5 and fluid bar seam 6.
Wherein, liquid knife plate 1 has two pieces, they relatively to should be able to closing lid together.The one side of two pieces of liquid knife plates 1 closing lids is mutually provided with three symmetrical grooves, when their closing lids together time these grooves correspondences form first cavity 3, second cavitys 5 and fluid bar seam 6, wherein fluid bar seam 6 is positioned at the bottom of liquid knife plate 1, first cavity 3 is positioned at the top of liquid knife plate 1, and the second cavity 5 is then positioned at the middle part of liquid knife plate 1; First cavity 3 is connected with the second cavity 5, and the second cavity 5 and fluid bar stitch 6 and be connected.The particularly important is, the cross section of the second cavity 5 is circular or oval, due to the existence of two cavitys and the arcuate structure of the second cavity 5, fluid can be made to obtain sufficient pressure equalization within it, namely after fluid enters the second cavity 5, after particularly full-bodied liquid enters the second cavity 5, fluid can be uniformly mixed wherein and eject from fluid bar seam 6, obtains like this presenting whole uniform waterfall (namely forming uniform spray figure 4).
In the present embodiment, the two ends (only showing the right-hand member of fluid bar seam 6 in Fig. 2) of fluid bar seam 6 are provided with the pilot flow 61 be connected with the second cavity 5, the width of pilot flow 61 stitches the width of 6 slightly larger than fluid bar, make liquid cutter can overcome the surface tension of liquid, spray figure 4 can thoroughly be opened without the need to high pressure, avoids the phenomenon of inwardly shrinking.Two pieces of liquid knife plates 1 are fixed by multiple screw 2, and a neat row lined up by these screws 2, between the first cavity 3 and the second cavity 5, can improve the constant intensity between two pieces of liquid knife plates 1.The shape in the first cavity 3 cross section can by multiple, such as square, circular or oval.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
