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, only basic structure of the present invention are 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 flow brake function, comprise the upper cover 2 and lower cover 4 that are connected to each other with internal and external threads, upper cover 2 and lower cover 4 are cylindrical shape, the open-top screw thread of upper cover 2 lower end and lower cover 4 upper end is connected to each other, upper cover 2 upper end and lower cover 4 lower end are respectively equipped with little opening, the spool 10 of pop-up 6 is upward through the little opening in upper cover 2 upper end, the spool 10 of subiculum 8 is down through the little opening in lower cover 4 lower end, spool 10 is tubular structure, yarn 24 can hollowly enter in sacculus 14 by it smoothly, pop-up 6 and subiculum 8 opposite end 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 direction is provided with 2-4 blister cavities 16, blister cavities 16 inner wall shape is elliposoidal, elliposoidal major axis is vertical direction arranged in co-axial alignment, each blister cavities 16 inside is equipped with the tension force ellipsoid 18 that an outside dimension is slightly less than blister cavities 16 internal diameter, be communicated with by yarn road between adjacent blister cavities 16, so just form yarn path of the present invention: from subiculum 8 spool 10, to gap between the inner blister cavities 16 of sacculus 14 and tension force ellipsoid 18, terminate to pop-up 6 spool 10 again, form the yarn path of an inner wall smooth.
The spool 10 of pop-up 6 stretches out upper cover 2 part and is provided with the compressed air interface 22 be tilted in the middle part of lower sensing tensioner, the spool 10 of subiculum 8 stretches out lower cover 4 part and is provided with the compressed air interface 22 tilting upward and point in the middle part of tensioner, two compressed air interfaces 22 are all communicated with spool 10, the compressed air interface 22 be obliquely installed can be easy to compared with slight drag compressed air is sent in the middle part of tensioner sacculus 14 from the spool 10 of tensioner one end in and flow out from the tensioner other end.The spring be located on the spool 10 of pop-up 6 is provided with in upper cover 2 inside, be provided with in lower cover 4 inside the spring be located on the spool 10 of subiculum 8 simultaneously, two springs all by pop-up 6 and upper cover 2 or subiculum 8 and lower cover 4 spacing inner at tensioner, spring can be easy to pop-up 6, subiculum 8 and the soft contact of sacculus 14 three between upper cover 2 lower covers 4, reducing the hard collision of sacculus 14 and tensioner upper cover 2 and lower cover 4, making yarn 24 by being not easy during tensioner to be subject to external force impact.
The surface of tension force ellipsoid 18 bottom of the present invention is provided with gas leakage groove 20, its another part smooth surface, the air that the compressed air interface 22 be connected with the spool 10 of pop-up 6 like this flows out at a high speed district flows out through subiculum 8 spool 10 downwards through sacculus 14 from the top down, air can flow out from the gas leakage groove 20 of tension force ellipsoid 18 bottom with the hole of sacculus 14 inwall smoothly, and yarn 24 also can be driven by air-flow the yarn path passing through tensioner inside through spool 10 sacculus 14 and gas leakage groove 20.The air that compressed air interface 22 high velocity stream be connected with the spool 10 of subiculum 8 is gone out upwards flows out through pop-up 6 spool 10 through sacculus 14 from bottom to top, tension force ellipsoid 18 top is blowed the upper surface to sacculus 14 inwall by air-flow, sacculus 14 and tension force ellipsoid 18 are pressed together at an upper portion thereof, and the yarn 24 be between sacculus 14 and tension force ellipsoid 18 is mutually extruded to be formed to grip resistance and then move to yarn 24 by sacculus 14 inside and tension force ellipsoid 18 outer surface and forms braking.
The present invention in use, as shown in Figure 3, in the first situation, when yarn 24 1 free end is 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 makes yarn 24 to pass through, when yarn 24 arrives tension force ellipsoid 18 bottom, yarn 24 can with air-flow through gas leakage groove 20, thus 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 terminates, stop sending into compressed air, in the second situation, yarn 24 moves in tensioner, compressed air flows into tensioner from the compressed air interface 22 of the spool 10 of subiculum 8, tension force ellipsoid 18 is upwards blowed the top to each sacculus 14 by compressed air, tension force ellipsoid 18 and sacculus 14 are extruded mutually in sacculus 14 upper inside wall yarn 24 is choked, and then the motion gripping resistance formed yarn 24, the active force superposition of multiple blister cavities 16 internal tension ellipsoid 18 can form larger gripping brake force to yarn 24, and yarn 24 can not be made so to be a bit subject to larger grasping force at certain cause large pressure and rupture, because the air-flow that each tension force ellipsoid 18 is subject to upwards blow air is not constant, sealing between each tension force ellipsoid 18 and blister cavities 16 is owing to lacking the setting of sealing ring, can not seal completely, so can bob be there is in tension force ellipsoid 18 in the blister cavities 16 at its place, beating of an interior tension force ellipsoid 18 is inconsistent, the grasping force superposition of multiple tension force ellipsoid 18 can make to grip the comparatively stable state of resistance maintenance, this process is yarn 24 braking procedure, after completing yarn 24 braking, stop compressed-air actuated entering.After the first situation terminates to stop sending into compressed air, when yarn 24 moves along yarn path from top to bottom in tensioner, tension force ellipsoid 18 can be pressed in the bottom of its place blister cavities 16 due to the existence of gravity, and then certain grasping force is formed to yarn 24, due to the existence of the groove 20 that leaks gas, yarn 24 can move along one of them gas leakage groove 20, make grasping force compared with do not exist gas leakage groove 20 when less, multiple tension force ellipsoid 18 be arranged above and below superposition several less grasping force form an overall stability, lasting yarn 24 tension force controls, under multiple tension force ellipsoid 18 can prevent only having tension force ellipsoid 18 situation, some tension force ellipsoids 18 are due to the grasping force extinction tests formed of beating.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can 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 right.
