The following specific embodiment further specifies the utility model in connection with above-mentioned accompanying drawing.
The specific embodiment
See also Fig. 1, anti-shake plate 100 described in the utility model is roughly a platy structure, and it comprises first 10 and second portion 20 that one connects.This first 10 is platy structure.This second portion 20 is platy structure also, offers some through holes 21 on it.The shape of this through hole 21 is not limit, and can be the hole of circular port, square hole, slot, slotted eye, tri-angle-holed or other shapes.
This second portion 20 has an end 23, and this end 23 can be set to have certain radian and upwarp.
The Length Ratio of this second portion 20 and first 10 is (1:10)-(1:1).
See also Fig. 2, a kind of object conveying device of using above-mentioned anti-shake plate 100, this object are frivolous sheets, such as paper web, plastic film or cloth and so on.Present embodiment adopts the paper apparatus 200 of copying of field of papermaking to describe.This copies the paper web 220 that paper apparatus 200 comprises deflector roll 210 and move under the drive of deflector roll 210, carry without support these paper web 220 belows.These anti-shake plate 100 parallel tops that are fixedly installed on the paper web 220 of high-speed mobile (500-1800m/min).The moving direction of this paper web 220 is consistent with the direction that first 10 points to second portion 20.
Understandable, this object conveying device is not limited to copy paper apparatus 200, and namely this paper web 220 is replaceable other frivolous sheets that are, such as plastic film or cloth and so on.
When the paper web 220 of high-speed mobile not yet moves to the below of anti-shake plate 100, produce air-flow around the paper web, air-flow velocity very fast (annotating: can produce air-flow around when objects at high speed moves).
When paper web 220 moves to the below of first 10, the space of paper web 220 tops diminishes, and according to the fluid mechanics theorem, the air-flow velocity of paper web 220 tops can increase thereupon.And according to Bernou1li equation as can be known: along with the increase of the air-flow velocity of paper web 220 tops, the air pressure of paper web 220 tops can diminish, the air pressure of paper web 220 belows is greater than the air pressure of paper web 220 tops at this moment, pressure difference can make paper web 220 produce the trend (generation of pressure difference makes paper web 220 be subject to one and upwards pressure, and this pressure is more than or equal to the weight of paper web) of first 10; In addition in the paper-making process paper web 220 with static, with first 10 near the time also can produce suction, make paper web 220 stable, can effectively prevent the shake of paper web 220.
Annotate: Bernou1li equation is:
, it is for all fluids, and wherein p is pressure, and ρ is density, and g is acceleration due to gravity, and h is height, and v is speed, and c is constant.Fluid herein is air, so can ignore gravity, Bernou1li equation can be reduced to:
, therefore higher according to the Bernou1li equation fluid velocity, pressure is less.
Should try one's best smoothly in first 10 and paper web 220 relative surfaces, prevent that 10 pairs of paper web 220 surfaces of first exert an influence under the pressure difference effect, affects paper web 220 quality.
When paper web 220 moves to the below of second portion 20, because the existence of through hole 21, the pressure difference of the above and below of paper web 220 reduces gradually, makes paper web 220 break away from gradually anti-shake plate 100.
When paper web 220 leaves the below of anti-shake plate 100 fully, paper web 220 recovers the most initial state.
For making paper web 220 break away from smoothly anti-shake plate 100, the end 23 of described second portion 20 can be set to have certain radian and upwarp; Or described some through holes 21 are set to along first 10 to second portion the mode that 20 direction increases gradually reaches the purpose that pressure difference is steadily reduced.
In conjunction with copying the paper speed of a motor vehicle and copying the paper indoor environment and calculate anti-shake plate 100 and the distance of paper web 220 and size and the density of through hole 21, pressure is steadily reduced, prevent because the air pressure sudden change causes the paper web shake.
The speed of a motor vehicle is different, and the size that through hole 21 need to be set is different with density, could arrive to prevent the effect of shaking.
The general speed of a motor vehicle is in the situation of 500-1800m/min, if this through hole 21 is circular port, the diameter of its through hole 21 is 5-20mm, and adjacent two pitchs of holes are 1-4 times of through hole 21 diameters.
If this through hole 21 is square hole, then through hole 21 length of sides are 5-20mm, and adjacent two pitchs of holes are 1-4 times of through hole 21 length of sides.
If this through hole 21 is slot, the length of its through hole 21 is 10-100mm, and the width of through hole 21 is 5-20mm, and pitch of holes is 1-4 times of through hole 21 width.The length direction of this rectangular through hole 21 is consistent with the moving direction of paper web.
If this through hole 21 is other shape, size and pitch of holes that its via area size, pitch of holes can be joined the through hole 21 of above-mentioned circle, square or rectangular arrange.
It should be noted that the closest range that above-mentioned adjacent two pitchs of holes are adjacent two holes.
The length of anti-shake plate 100 is moderate, long can affect first 10 not steady with the pressure of paper web 220 contact zones, does not too shortly then produce enough pressure differences, the effect of the steady paper web 220 of out of reach, this length also need determine with reference to the speed of a motor vehicle of paper web 220.The general speed of a motor vehicle is 500-1800m/min, and the length of anti-shake plate 100 is 500-2000mm.
Effect through anti-shake plate 100 has reduced jitter amplitude and the frequency of paper web 220 in paper-making process, makes whole paper-making process more stable, reduces disconnected paper chance, also makes and batches better effects if, and the raising body paper is copied and got quality.In addition, this anti-shake plate 100 is consumed energy not, and is simple in structure, can reach the effect that prevents the paper web shake, and installation is regulated, safeguards all fairly simple, and cost is lower, and more energy-conserving and environment-protective can arrange installation in a plurality of positions in whole paper-making process.
In addition, those skilled in the art also can make various modifications, interpolation and the replacement on other form and the details in the utility model claim scope of disclosure and spirit.Certainly, these all should be included within the utility model scope required for protection according to the variations such as various modifications, interpolation and replacement that the utility model spirit is made.
