Technical field

The utility model relates to a kind of special shearing device.Say definitely, the utility model is a kind of being used for animal fiber (such as wool), along the staple length direction, segmentation cuts the fiber fragment of different length, for the sampler of test, the fineness of studying wool fibre and evenness (fineness along the staple length direction changes).

Background technology

Along with the continuous development of textile industry, more and more higher in recent years to the quality requirements of textile raw material, particularly more and more be subjected to the attention of wool spinning as the fineness of the wool fiber of large wool textile raw material and evenness.According to the study, the spinnability 80% of wool fiber is by its fineness and evenness decision.Scopular evenness is poor more, and its tender wool is just serious more, and the existence of tender wool is very harmful concerning textile industry, it makes wool in combing and carded process, and fuds fuddled increases, and the row yielding of wool reduces, and fibre length reduces in the wool top, and brute force diminishes, and the durability of fabric is reduced.

Animal fiber is as a kind of natural fiber, and its uniform fineness is influenced by kind, individual character, age, sex, nutrition, weather etc.Same hair can be because of differences such as the nutrition condition of season of growth, growth period individuality, physiological situation (as pregnancy, lactation etc.), health status along the fineness of staple length direction, domestic wool particularly, because the climate change of its growth phase is big, nutrition supply is unbalanced, alter a great deal along the fineness of staple length direction.Studies show that homemade fine wool increases to the high-quality green tea fineness gradually along hair root, the nearly 9 μ m of maximum difference.Liu keeps benevolence academician etc. and the annual wool growth of the Chinese merino double-toothed ewe of the purple earth spring sheep stud in Xinjiang and quality are changed studies, and the result shows that its fineness of wool of Various Seasonal growth is discrepant.Therefore, according to variation along staple length direction fineness, can study of the influence of the seasonal variety of a certain growth section sheep nutrition, health status and herbage nutrition only to wool quality, thereby study and define rational feeding and management scheme, by artificial nutrition regulation, make the only annual nutrition supply equilibrium of sheep, improve wool quality.In addition, by under the identical feeding and management condition, the analytical test of Different Individual scopular evenness, can study Different Individual, adaptability to changes to environmental change, environmental change is just produced the hair Effect on Performance to Different Individual, selects the more blunt sheep of environmental change reaction is only carried out selection cross, cultivates the fine-wool sheep kind that can adapt to varying environment.Therefore, the test of scopular evenness is bred textile industry, fine-wool sheep all positive directive function.

At present, the instrumentation of domestic professional test scopular evenness still belongs to blank, and great majority are with the Ha Shi food slicer fiber to be carried out gradation segmentation sampling, detect with microscopic projector or other fineness testing tool again, analyze its fineness then and change.The Ha Shi food slicer has two metal platen, wherein on a metal platen protruding tongue is arranged, and is fluted on another piece metal platen, and two metal platen are meshed, and a certain size space is arranged between groove and the protruding tongue, and sample is just filled out in this space.The space that forms between metal platen is provided with and the corresponding to little push rod of pore size, and controls the position of push rod in the space with screw rod.Rotary screw in the use travels forward push rod and the fibrous bundle head is released the front end of metal platen, after the pieces length of being released reaches sample length and requires, again with sharp blade along metal platen front end face cutting-out sample section.Cut a fiber samples with the Ha Shi food slicer, minimumly will cut two cuttves, and cut the sample limited amount at every turn.In addition, cut sample with the segmentation of Ha Shi food slicer, disarray scopular easily, its operating difficulties is cut the sample number of times and is restricted thereby make.Therefore, the sample of cutting in China's present wool fibre fineness test is to cut position, scopular middle part basically, and the test of scopular evenness only usually only the branch upper, middle and lower cut sample for three sections, and the position of cutting sample can not quantize to determine.Like this, the representativeness of sample is all relatively poor with the accuracy of cutting the sample position, thereby influences precision of test result.Bring difficulty for the research work of domestic staple formation.At present, the instrument that is used for the evenness test in the world has only the FDA2000 of Australia's production, this instrument is to adopt laser scanner technique, need not cut sample, whole Shu Maocong is carried out the test of fineness every certain distance along its length direction, analyze its fineness then and change, but this instrument costs an arm and a leg, and is difficult to popularize.
