Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As depicted in figs. 1 and 2, a kind of tensioner with air-flow braking function, comprise with the interconnected upper cover 2 of internal and external threads and lower cover 4, upper cover 2 and lower cover 4 are cylindrical shape, the open-top screw thread of upper cover 2 lower ends and lower cover 4 upper ends is connected to each other, upper cover 2 upper ends and lower cover 4 lower ends are respectively equipped with little opening, the spool 10 of pop-up 6 is upward through the upper cover 2 little openings in upper end, the spool 10 of subiculum 8 is down through the lower cover 4 little openings in lower end, spool 10 is tubular structure, yarn 24 can be smoothly by its hollow entering in sacculus 14, pop-up 6 and subiculum 8 opposite ends are equipped with the semielliptical shape concave surface of relative orientation, semielliptical shape concave edge is fixedly connected with two free ends of sacculus 14, sacculus 14 vertical directions are provided with 2-4 blister cavities 16, blister cavities 16 inner wall shape are elliposoidal, elliposoidal major axis is vertical direction arranged in co-axial alignment, each blister cavities 16 inside are equipped with an outside dimension and are slightly less than the tension force ellipsoid 18 of blister cavities 16 internal diameters, between adjacent blister cavities 16, be communicated with by yarn road, so just form yarn path of the present invention: from subiculum 8 spools 10, to gap between the inner blister cavities 16 of sacculus 14 and tension force ellipsoid 18, finish to pop-up 6 spools 10 again, form the yarn path of an inner wall smooth.
The spool 10 of pop-up 6 stretches out upper cover 2 parts and is provided with the compressed air interface 22 that is tilted to lower sensing tensioner middle part, the spool 10 of subiculum 8 stretches out lower cover 4 parts and is provided with the compressed air interface 22 that tilts to be directed upwards towards tensioner middle part, two compressed air interfaces 22 are all communicated with spool 10, and the compressed air interface 22 being obliquely installed can be easy to compressed air is sent in the sacculus 14 in the middle part of tensioner and being flowed out from the tensioner other end from the spool 10 of tensioner one end compared with slight drag.Be provided with the spring on the spool 10 that is located in pop-up 6 in upper cover 2 inside, be provided with the spring on the spool 10 that is located in subiculum 8 in lower cover 4 inside simultaneously, two springs are all spacing in tensioner inside by pop-up 6 and upper cover 2 or subiculum 8 and lower cover 4, spring can be easy to pop-up 6, subiculum 8 and the soft contact of sacculus 14 three between 2 lower covers 4 of upper cover, reduce the hard collision of sacculus 14 and tensioner upper cover 2 and lower cover 4, while making yarn 24 by tensioner, be not easy to be subject to external force impact.
The surface of tension force ellipsoid of the present invention 18 bottoms is provided with gas leakage groove 20, its another part smooth surface, the air that the compressed air interface 22 being connected with the spool 10 of pop-up 6 like this flows out at a high speed district flows out through subiculum 8 spools 10 downwards through sacculus 14 from the top down, air can flow out from the gas leakage groove 20 of tension force ellipsoid 18 bottoms and the hole of sacculus 14 inwalls smoothly, and yarn 24 also can be driven through spool 10 sacculus 14 and the smooth yarn path through tensioner inside of gas leakage groove 20 by air-flow.The air that compressed air interface 22 high velocity stream that are connected with the spool 10 of subiculum 8 are gone out upwards flows out through pop-up 6 spools 10 through sacculus 14 from bottom to top, air-flow blows tension force ellipsoid 18 tops to the upper surface of sacculus 14 inwalls, sacculus 14 and tension force ellipsoid 18 are pressed together at an upper portion thereof, and the yarn 24 being between sacculus 14 and tension force ellipsoid 18 is mutually pushed formation gripping resistance and then yarn 24 is moved and forms braking by sacculus 14 inside and tension force ellipsoid 18 outer surfaces.
The present invention in use, as shown in Figure 3, in the first situation, when yarn 24 1 free ends are placed on spool 10 place suitable for reading of pop-up 6, compressed air flows into tensioner from the compressed air interface 22 of the spool 10 of pop-up 6, due to negative pressure, yarn 24 can be inhaled into tensioner and enter each blister cavities 16 of sacculus 14 with compressed air, gap between blister cavities 16 and tension force ellipsoid 18 can be passed through yarn 24, when yarn 24 arrives tension force ellipsoid 18 bottom, yarn 24 can be with air-flow through gas leakage groove 20, thereby yarn 24 can enter the spool 10 of subiculum 8 successively from top to bottom by each blister cavities 16, finally leave tensioner, this process is pneumatic entry process, after pneumatic entry finishes, stop sending into compressed air, in the second situation, yarn 24 has moved in tensioner, compressed air flows into tensioner from the compressed air interface 22 of the spool 10 of subiculum 8, the compressed air of tension force ellipsoid 18 upwards blows to the top of each sacculus 14, make tension force ellipsoid 18 and sacculus 14 mutually push yarn 24 is choked in sacculus 14 upper inside wall, and then formation grips resistance to the motion of yarn 24, the active force stack meeting of multiple blister cavities 16 internal tension ellipsoids 18 forms larger gripping brake force to yarn 24, and can not make like this yarn 24 a bit be subject to causing large pressure and rupturing compared with large grasping force at certain, because it is not constant that each tension force ellipsoid 18 is subject to the air-flow that upwards air blows, sealing between each tension force ellipsoid 18 and blister cavities 16 is owing to lacking the setting of sealing ring, can not seal completely, can there is bob so the blister cavities 16 of tension force ellipsoid 18 at its place is interior, beating of an interior tension force ellipsoid 18 is inconsistent, the grasping force stack of multiple tension force ellipsoids 18 can make to grip resistance and keep comparatively stable state, this process is yarn 24 braking procedures, complete after yarn 24 brakings, stop compressed-air actuated entering.The first situation finishes to stop sending into after compressed air, when yarn 24 moves along yarn path from top to bottom in tensioner, tension force ellipsoid 18 is because the existence of gravity can be pressed in the bottom of its place blister cavities 16, and then yarn 24 is formed to certain grasping force, due to the existence of gas leakage groove 20, yarn 24 can move along one of them gas leakage groove 20, make grasping force compared with do not exist gas leakage groove 20 situation under less, multiple tension force ellipsoids 18 several less grasping forces of stack that are arranged above and below form an overall stability, lasting yarn 24 tension force controls, multiple tension force ellipsoids 18 can prevent from only having some tension force ellipsoids 18 in tension force ellipsoid 18 situations due to the grasping force extinction tests of beating and forming.
Be enlightenment according to desirable embodiment of the present invention above, by above-mentioned description, related personnel can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to claim scope.
