Detailed description of the invention
The present invention is described in further detail to lift a specific embodiment below in conjunction with accompanying drawing.
Please refer to Fig. 1-4, a kind of flexible sponge sucker system, comprises spongy layer 1, unidirectional valve layer 2, airtight cavity 3 and framework 4.Unidirectional valve layer 2 comprises multiple check valve, described check valve comprises valve body 21, valve ball 22, valve port and derby 23, derby 23 is preferably copper billet, valve pocket 24 is provided with in valve body 21, valve ball 22 can be movable in valve pocket 24, metallic filtering gauze sheet 25 is provided with between valve ball 22 and valve port, derby 23 is arranged at the top of valve pocket 24, derby 23 forms a hemispherical dimples 28 towards the end face of valve ball 22, the shape of this hemispherical dimples 28 is identical with the surface of valve ball 22, the bottom of hemispherical dimples 28 is provided with longitudinal hole 26, derby 23 athwartship plane is also provided with cross through hole 27, cross through hole 27 one end is communicated with longitudinal hole 26, the other end is communicated with the valve pocket 24 of check valve, the bore of cross through hole 27 is less than the bore of longitudinal hole 26, spongy layer 1 comprises foam-rubber cushion 11, filter screen 12 and rubber pad 13, foam-rubber cushion 11, filter screen 12 is connected successively with rubber pad 13, foam-rubber cushion 11 and rubber pad 13 are all provided with corresponding bottom outlet 14, and bottom outlet 14 is at least one, filter screen 12 does not establish bottom outlet 14.Spongy layer 1 also comprises mucigel 15, described mucigel 15 is provided with the perforation adapted with the bottom outlet 14 on described foam-rubber cushion 11 and described rubber pad 13.According to difformity and the feature of product, bottom outlet 14 is changeable, can justify can just, can closely dredge, can Bao Kehou, various uneven can be adapted to, and then play good sealing function.
Be located in framework 4 in unidirectional valve layer 2 and airtight cavity 3, the material of airtight cavity 3 and framework 4 is preferably aluminum alloy.The bottom of airtight cavity 3 connects each check valve in unidirectional valve layer 2 by longitudinal hole 26, top connects vacuum lamp by vacuum tube joint 5.Spongy layer 1 is fixed on below framework 4 by mucigel 15, on spongy layer 1, each bottom outlet 14 is corresponding with each valve port of check valve, and being airtightly fixed on bottom outlet inner end, the bottom outlet on spongy layer, filter screen, metallic filtering gauze sheet, check valve valve pocket and longitudinal hole form a gas circuit.
At startup vacuum pump in a flash, air enters check valve by the bottom outlet 14 on spongy layer 1 from check valve valve port, valve ball 22 in all check valves is pushed up in hemispherical dimples 28, because the shape of hemispherical dimples 28 is identical with the surface of valve ball 22, therefore, by the gas circuit of longitudinal hole 26 to blocking, and cross through hole 27 will continue air intake, when workpiece 6 contacts with any one or more bottom outlets 14 on spongy layer 1, bottom outlet 14 is blocked by workpiece 6.Afterwards, the air in bottom outlet 14 is pumped, and the application force of the air in valve pocket 24 to valve ball 22 reduces gradually, under the combined action of valve ball 22 self gravitation and airtight cavity 3 internal pressure, valve ball 22 is fallen, and the air that valve pocket is 24 li is taken away instantaneously, and workpiece 6 is sucked; And other are several not by bottom outlet 14 that workpiece 6 is blocked, owing to exposing in atmosphere, below valve ball, the air pressure of bottom outlet end is greater than the application force and valve ball 22 self gravitation sum that air in airtight chamber 3 produces valve ball 22, therefore valve ball 22 can not fall, longitudinal hole 26 continues to be blocked by valve ball 22, the vacuum of airtight chamber 3 can not be destroyed, even if Here it is, workpiece 6 does not cover bottom outlet 14 completely, the reason that also can not drop.Because spongy layer 1 has characteristic that is soft and sealing, it can change shape with the different profile of workpiece 6, therefore, spongy layer 1 can reach optimum efficiency with the contact surface of workpiece 6, is no matter that sheet material or beverage bottle or other fitfull contact surfaces can be held, in addition, spongy layer 1 is dispersed with a lot of bottom outlets 14, each bottom outlet 14 correspond to again a check valve, so workpiece 6 only need contact with the random one or more bottom outlets 14 on spongy layer 1 and just workpiece 6 can be held.
Be only specific embodiments of the invention disclosed in above-mentioned, this embodiment is only that clearer explanation the present invention is used, and is not limitation of the invention, and the changes that any person skilled in the art can think of, all should drop in protection domain.
