Abstract
The utility model discloses a testing and sampling device for carbon fiber tow linear density. The testing and sampling device comprises a measuring scale and a cutting knife, wherein the measuring scale comprises three cushions plates consisting of a first limiting cushion plate, a value-reading cushion plate and a second limiting cushion plate, which are fixedly connected on the bottom plate in sequence and the same in height; a first cutting gap is formed between the first limiting cushion plate and the value reading cushion plate; a second cutting gap is formed between the value reading cushion plate and the second limiting cushion plate; the width of the first cutting gap is the same as that of the second cutting width; the knife body thickness of the cutting knife is equal to the width of the first cutting gap; the sum of set length of the value reading cushion plate and the width of the first cutting gap is equal to a carbon fiber tow linear density testing and sampling predetermined value; the carbon fiber tows are leveled and placed on the measuring scale; and the cutting knife is respectively used for cutting at the first cutting gap and the second cutting gap, so that obtained value is the carbon fiber tow linear density testing and sampling predetermined value. Besides, the testing and sampling device for the carbon fiber tow linear density is capable of avoiding the errors caused by manual naked-eye observation of the operation, so that the value reading is more accurate.
Description
Technical field
The utility model relates to a kind of carbon fibre tow line density test sampler.
Background technology
Carbon fiber is in the newer, high-performance fiber materials more than 92% by a kind of carbon content, have multiple excellent properties such as high specific strength, high ratio modulus, high temperature resistant, corrosion-resistant, antifatigue, conduction, heat conduction and far infrared radiation, being widely used in Aero-Space, military and national defense, sports apparatus and industrial circle, is national important strategic basic material.
Carbon fiber is a kind of new material of mechanical property excellence, it not only has the inherent characteristic of material with carbon element, the soft processibility that has both textile fibres again be fortifying fibre of new generation, so the properties of carbon index comprises line density, pulling strengrth, breaking elongation, stretch modulus, density etc.About the existing corresponding testing standard of the above-mentioned performance index of carbon fiber, be example with the carbon fiber line density measurement, require 1 meter of sample length, error is ± 0.5mm.
At present, usually the method that adopts is that carbon fiber bundle is placed on the meter ruler, and carbon fiber bundle is stretching, with the length of 1 meter of scissors clip with the weighing of ten thousand/balance.The method scissors must be between carbon fiber bundle and meter ruler, carbon fiber bundle is unsettled to lean on the projection of human eye range estimation fibrous bundle on the meter ruler scale manually to shear, but adopt the error of said method clip sample to be difficult to assurance ± 0.5mm, thereby influence the test result of carbon fiber line density, and troublesome poeration.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of easy operating, value carbon fibre tow line density test more accurately sampler.
For solving the problems of the technologies described above, the utility model provides a kind of carbon fibre tow line density test sampler, it is characterized in that: comprise dip stick and cutter;
Described dip stick comprises three the highly identical backing plates of fixedly ining succession successively on the base plate, be respectively that the first restriction backing plate, value backing plate and second limit backing plate, between the first restriction backing plate and the value backing plate first cutting gap is arranged, value backing plate and second limits between the backing plate second cutting gap, and the first cutting gap width is identical with the second cutting gap width;
The blade thickness of described cutter equals the width of first cutting gap and second cutting gap.
After adopting such structure, set length, the first cutting gap width and the second cutting gap width of value backing plate earlier, make the length of value backing plate add that the first cutting gap width equals carbon fibre tow line density test sampling predetermined value, again carbon fiber bundle is evened up and be placed on the dip stick, cut at first cutting gap and the second cutting gap place respectively with cutter at last, the line density of the carbon fibre tow just test sampling predetermined value that obtains, use simple and convenient, and avoid operating the error of bringing by artificial visual inspection, value is more accurate.
Below in order to understand technology contents described in the utility model better, more easily, abbreviate the utility model carbon fibre tow line density test sampler as this device.
The blade of the cutter of this device makes that in the centre position of cutting blade thickness direction projection reducing the blade deviation brings error for the intercepting carbon fibre tow.
The long 999.5mm of value backing plate of this device, the width of first cutting gap is 0.5mm, usually carbon fibre tow line density test sampling predetermined value is 1m, and the error that guarantees sampling adopts such structure within ± 0.5mm, guarantees accurate value.

Fig. 3 is the front elevation of this device embodiment.
Fig. 4 is the partial enlarged drawing of the A part of Fig. 3.
Embodiment
Shown in Fig. 1 to 4, dip stick 1 is accurately cut at the length place of 999.5mm by a Steel Ruler (length overall can greater than 1m); The steel ruler that 0mm to 999.5mm is long partly is welded on and is value backing plate 13 on the steel substrate 11; Steel ruler remainder under the cutting is cut two again, be respectively first and limit backing plate 12 and the second restriction backing plate 14, first limits backing plate 12 is welded on the base plate 11, and makes first restriction backing plate 12 rear end faces and value backing plate 13 front end faces accurately leave first cutting gap 15 that width is 0.5mm; Second limits backing plate 14 is welded on the base plate 11, and makes second to limit backing plate 14 front end faces and value backing plate 13 rear end faces accurately to leave width be that second cutting gap 16, the first of 0.5mm limits backing plates 12, value backing plate 13 is highly identical with the second restriction backing plate 14.
During use, place on the dip stick 1 carbon fibre tow 3 stretching and live (drawing of illustrating of figure with hand, for convenient understanding content of the present utility model has carbon fibre tow 3 at interval in dip stick 1, reality is adjacent on the dip stick 1 for carbon fibre tow 3), cutter 2 with 0.5mm thickness cut at first cutting gap 15 and second cutting gap, 16 places simultaneously, 16 the first center line 4b that the blade 22 of cutter 2 is aimed at 15 the first center line 4a of first cutting gap and first cutting gap respectively cuts vertically downward, because of the thickness of cutter 2 identical with second cutting gap 16 with first cutting gap 15, carbon fibre tow 3 respectively has more 0.25mm in value backing plate 13 both sides, the length of Jie Qu carbon fibre tow 3 is exactly 1000mm like this, use this directional error much smaller than ± 0.5mm, almost can ignore, thereby guarantee the accuracy of carbon fibre tow line density test sample length, and then guarantee carbon fibre tow line density precision of test result.
Above-described only is a kind of embodiment of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle; can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
