Description
Technical field
The present invention relates to a kind of fabric test instrument, particularly a kind of fabric thickness high speed tester device.
Background technology
The thickness of fabric refers to fabric vertical range between positive and negative two seating surfaces under certain pressure, take " mm " as measurement unit.Line density, fabric tissue and the yarn degree of crook in fabric that the principal element that affects fabric thickness is filling yarn etc.Fabric thickness is larger on the impact of wearability of fabric, as the performances such as fastness, gas penetration potential, warmth retention property, windproof property, drapability and hard and soft property of fabric.Fabric can be divided into slim, medium-thick type and thick type three classes by the difference of thickness.
The method of testing of general fabrics thickness is: fabric sample is placed on reference plate, the presser feet that is parallel to reference plate puts on authorised pressure (saddle weight) on sample regulation area, measure after stipulated time and record the vertical range between two plates, being the sample thickness measured value.
The thickness of fabric is tested with thicknessmeter.Two kinds of forms are arranged at present, and a kind of is mechanical, and it is to be connected in ratch with presser feet, by a series of fan type tooth plates and gear and a kind of device of transmission needle pivot.Each scale of index dial represents 1/100mm, and the scale that the pointer indication dial disc is corresponding is fabric thickness.Another kind is electronic type, with presser feet, is connected in interior bar, and by a series of machinery and electric signal conversion, the liquid crystal display of instrument shows thickness, and its resolution is 1/100mm.There is following defect in these testing tools: 1,, according to the requirement of GB3820-1997 standard, the variety classes fabric needs different moulding pressures, and its required moulding pressure is also different, and therefore, thicknessmeter need to have the saddle weight of multiple different size, 2, mechanical displacement or drift can occur later (when presser feet contacts with reference plate using in instrument, pointer is the indication dial disc zero-bit not, perhaps the liquid crystal display displayed value exceeds allowed band), while causing again measuring, before putting sample, dial needle indication or display screen show non-vanishing, therefore before starting test or every test all to recalibrate zero-bit several times, as mechanical thicknessmeter, when presser feet contacts with reference plate, if it is unpunctual that pointer and index dial zero-bit slightly have, by the zero-bit control hand wheel, proofreaied and correct, arc profile of tooth tooth bar is housed on index dial, pinion wheel engagement with control hand wheel, the zero graduation line can be calibrated in the position of rotation scale, then make presser feet move up and down 2-3 time together with ratch, whether observe pointer also in zero-bit, if do not calibrated again also needing, until pointer refers in zero-bit.Thicknessmeter for electronic type, when presser feet contacts with reference plate, if it is non-vanishing that display screen shows, need to adjust the zero-bit of dial gauge, if zero difference is more than 0.20mm, available dial gauge bottom is exposed 8 milled screws and is adjusted, coordinate rotation dial gauge shell to be finely tuned, mix up zero-bit, empty examination several times, official testing again after zero-bit is stable, in test process, interval to observe the zero-bit situation, if (while not putting fabric) be not in zero-bit (during empty examination zero-bit when unloaded, exceed ± 0.005mm of zero drift), need to repeatedly adjust.So repeatedly, cause whole test process loaded down with trivial details, accurate, consuming time larger for guaranteeing test result.3,, during the thickness of test fabric different parts, need to mention presser feet, moving fabric, and to guarantee fabric smooth, without tension force be placed on reference plate, this process is more loaded down with trivial details, and the fabric state is easy to change, cockline, cause final testing result inaccurate; 4, due to thicknessmeter be by presser feet, connected in bar (ratch), so above saddle weight is put into presser feet the time, the actual force value be applied on fabric is less than the sign value of saddle weight, causes test result bigger than normal.When electronic thickness gauge carries out reading by machinery and electric signal conversion, can be subject to the impact of electromagnetic interference (EMI) and temperature drift simultaneously, cause test result inaccurate also unstable; The mechanical type thicknessmeter, by a series of fan type tooth plates and gear drive needle pivot, makes pointer indicate test result at index dial, and this process can be subject to the impact of mechanical drag, also can be subject to the impact of the state of thicknessmeter own, makes test result inaccurate simultaneously.These two kinds of testing tools are particularly outstanding for the test result impact of zephyr.5, in electronic thickness gauge test process one-period, presser feet and interior bar thereof move must have motor slowly drive rising or descend, this process can be adjusted sample site and change sample after finishing, when therefore experimental duties are heavier, expend time in longer, cause testing efficiency extremely low, be not suitable for inspection body or student experimenting real training needs.
