Description
Technical field
Glass wire density measurement collecting device relates to glass wire density measurement yarn fixed length sampler, is to the improvement of virgin glass fibre line density test with collecting device.
Background technology
On the glass fibre production line, regularly detecting the glass fiber precursor line density is one of main means that keep constant product quality.The assay method of glass fibre line density is the tested glass fiber yarn sample that accurately batches certain-length, claim after its weight, calculate the value of line density again.
In glass fiber industry, passive unwinding mode is all adopted in the sampling of the line density test yarn of widespread use at present.Promptly the precursor glass fiber yarn is moved back in the internal layer of bobbins by take-up mechanism or outer outside move back and pull out, bobbins itself is motionless.Be characterized in that bobbins itself has certain tapering (up-small and down-big), the yarn of reeling on the bobbins is to adopt short distance winding displacement mode.Move back in this way when separating yarn, the friction on glass fiber yarn and bobbins tube limit is less, and sampling comparatively fast, conveniently.But such bobbins package amount is generally smaller, and approximately every less than 1 kilogram, and it mainly is applicable to the glass fibre ball farad silk production that the package amount is little.
In recent years, along with the introduction of external advanced person's glass fibre tank furnace wire-drawing technology, original ball farad silk can't adapt to the pool kiln wiredrawing needs of big turnout with rouleau loading amount taper bobbins.In pool kiln wiredrawing production, replace the garden cylindricality hard bobbins that adopts the large package amount.Therefore, the glass fibre weaving spun yarn that present pool kiln wiredrawing technology is produced, the overwhelming majority has been wound on the hard bobbins.The characteristics of this hard bobbins have two: one,, the diameter of bobbins is upper and lower generally thick; The 2nd,, the bobbins quality is harder.Be the use of the bobbins that cooperates this big volume amount, the yarn winding method also adopts long-range winding displacement mode thereupon.Such bobbins package amount is general every only up to the 1-10 kilogram, can improve the package efficient that glass fibre is produced greatly.The hard bobbins of this kind large package amount is adopted at present about in the world glass fibre weaving spun yarn production more than 80%.
For the hard bobbins, because glass fiber yarn is to be tiled on the whole isometrical bobbins, as adopting free style unwinding sampling again, institute's glass fiber yarn of getting can rub with whole layer surface inevitably, also can constantly rub simultaneously with the tube limit of hard bobbins, gently then cause segment glass fibre single thread yarn samples impaired, heavy then cause the fracture of yarn.Impaired monofilament sample will inevitably influence precision of test result, in case and single wire fracture then influences normally carrying out of sampling.
Summary of the invention
The purpose of this utility model, be in the glass fiber yarn coiling sampling process at above-mentioned existence, yarn samples is easy to defective impaired or fracture, a kind of glass wire density measurement collecting device is proposed, it can carry out active unwinding, accurately fixed length sampling, guarantee the serviceability rate of the glass fiber yarn sample of getting, improve the efficient of yarn sampling and the accuracy of measurement result.
For achieving the above object, technical solution of the present utility model is as follows: it comprises unwinding device 1 and batch device 2, it is characterized in that: unwinding device 1 is driven by unwinding motor 3, batches device 2 and is driven by reel-motor 4; Unwinding motor 3 is by 5 controls of unwinding frequency converter, reel-motor 4 is by batching frequency converter 6 controls, near the long signal sensor of survey that batches 2 of the devices is connected with the input end of length detection controller 7, the output terminal of length detection controller 7 respectively with unwinding frequency converter 5, batch frequency converter 6 and be connected.
At unwinding device 1 with batch and also be provided with travel switch 8 between the device 2, it is fixed on the storage yarn bar 9, and the signal wire of travel switch 8 links to each other with the speed selection port of unwinding frequency converter 5.
The utility model is compared the advantage that has with existing passive type take-off device: this installs automatic control degree height, and it is accurate that fixed length is batched yarn.When the glass fibre spun yarn was taken a sample, the unwinding device can be realized initiatively unwinding, and with batch device run-in synchronism, reduced the friction between the yarn, guaranteed the serviceability rate of the glass fiber yarn sample of getting, improve the efficient that yarn takes a sample and the accuracy of measurement result.
