Embodiment

As shown in Figure 1, the utility model is from left to right provided with successively to control show case, motor housing and test desk on the plate face of rectangular support base plate 15.

Support baseboard 15, as supporting body, for supporting miscellaneous part, is provided with four supporting legs 6 in the bottom of support baseboard 15.

Control the high order end that show case is arranged on support baseboard 15, the front face of casing is provided with the human-computer interaction interface 2 of power switch 1, starting switch 3 and input and reading data; The controller for controlling each component working and the arithmetical unit for calculating data is provided with in the inside controlling show case.

Motor housing is arranged on the right side controlling show case, and be provided with stepper motor 16 in motor housing, for driving the helical screw of test desk inside to rotate, stepper motor 16 is also connected with controller, only controls its forward, reverse or stop by controller.Be provided with pulling force sensor 14 at the top (or inner) of motor housing, pulling force sensor 14, for gathering the value of thrust signal on tested yarn, when pulling force reaches setting value to controller transmission of signal, sends instruction control step motor 16 by controller and reverses.

As depicted in figs. 1 and 2, test desk is arranged on the right side of motor housing, its table top is rectangle, the table top of test desk is provided with the first clamper 4 and the second clamper 5 for clamping yarn samples, wherein, first clamper 4 is fixedly installed on one end of the close motor housing of test desk, and the first clamper 4 is connected with pulling force sensor 14; Second clamper 5 is fixedly installed on and along on the slide plate 10 of test desk left and right slippage, and can moves left and right with slide plate 10.Two clampers form by base and the chuck be hinged on base, and the end of yarn samples is pressed on base by chuck, to fix respectively the two ends of yarn.Be fixedly installed leading block 12 at the low order end of test desk table top, leading block 12 has coordinated the pulling force calibration operation before test with the first clamper 4.The table top of test desk is equipped with rule 11 along its length, when the spacing of setting two clampers, by observe the position of two clampers on rule 11 check space whether accurate; Rule 11 also can be used for measuring yarn samples be elongated after length, but how much all there is error, therefore fewer use due to artificial reading.

As shown in Figure 2, the helical screw 7 be in transmission connection with stepper motor 16 is provided with in the inside of test desk, helical screw 7 is socketed with nut 8, anti-rotation catch 9 is fixed with at the top of nut 8, when stepper motor 16 drives helical screw 7 to rotate, due to the stop of anti-rotation catch 9, nut 8 can not be rotated with helical screw 7, but drive anti-rotation catch 9 to move to the left or to the right along helical screw 7 together.Laterally offering strip through-hole 13 in the side of test desk, the window that the anti-rotation catch 9 as test desk inside is connected with outside slide plate 10, is also the moving conduit that anti-rotation catch 9 moves left and right with the connecting portion of slide plate 10.One end of anti-rotation catch 9 passes from the through hole 13 of test desk side, one end of slide plate 10 bends downwards and extends to through hole 13 place, cross with the end of anti-rotation catch 9, the intersection of the two is fixedly connected with by web member (as screw rod etc.), thus makes nut 8, anti-rotation catch 9, slide plate 10 and the second clamper 5 connect into an entirety.Thus, when opening stepper motor 16, under the effect of helical screw 7, the second clamper 5, along the table top slippage of test desk, changes the rotation direction of stepper motor 16, can control the second clamper 5 and move to left or move to right.

In order to avoid the error of artificial reading, and then measure the length that yarn samples is straightened more accurately, the utility model arranges scrambler 17 in one end of helical screw 7, scrambler 17 is connected with arithmetical unit, the air line distance of both conjunction measuring nut 8 movements, is the length that yarn is elongated, and arithmetical unit is doubly worth computing formula according to the hair set again, can show that the hair of this sample is doubly worth, final testing result is presented on human-computer interaction interface 2.

After having tested when one group, controller control step motor 16 rotates backward, and stops after making the second clamper 5 return to reference position, can start next group test.

In addition, the utility model also comprises embedded mini-printer, for the printout of test data; Also be provided with power-off protector in the inside controlling show case, if power-off suddenly in test, after again connecting with the mains, still can preserve the data originally done, and continue test.

Using method of the present utility model:

Force value is demarcated: turn on the power switch, enter value of thrust calibration interface, second clamper is pulled down, counterweight (counterweight as 100cN) corresponding for standard tension value with testing sample is hung over one end of cotton rope, the other end of cotton rope is by being clipped on the first clamper after leading block, display value stabilization to be verified is 100cN, verification completes, take off counterweight, exit calibration interface, the second clamper is installed back original position.

Setting is spaced and loading: open and measure interface, set space (the determining according to testing sample length) between two clampers, under the effect of controller, second clamper will be automatically moved to corresponding position, be sandwiched respectively in two clampers at the two ends of yarn samples to be measured after confirmation.

Start to detect: press starting switch, stepper motor rotates clockwise, and drives helical screw to rotate, and nut and anti-rotation catch are moved right along screw rod, and slide plate and the second clamper be slippage to the right thereupon also.When the value of thrust that pulling force sensor detects in tested yarn samples reaches setting value (as 100cN), namely signal is sent to controller, controller sends toggling command to stepper motor again, stepper motor rotates counterclockwise, drive helical screw reverse rotation, second clamper is moved to left, stops after getting back to reference position, wait for and testing next time.Meanwhile, scrambler reads the maximum distance (i.e. sample be elongated length) that nut moves right, and by data information transfer to arithmetical unit, the hair being calculated sample by arithmetical unit is doubly worth.
