Floccus sectionalized sample cutting instrument

Abstract

The invention relates to a device for cutting animal hair under certain requirement to do research or be used in other special situation, which comprises an immovable knife holder, and a movable knife holder fixed on the immovable knife holder by a hinge; wherein, the movable knife holder comprises a U-shaped device with a handle, a movable knife clamping device fixed on the U-shaped device by a bolt, and at least two movable knives. The U-shaped device is provided with a hole matching the hinge. The immovable knife holder is provided with a plurality of immovable knives that are matching with the movable knives and have the same number of holes of the movable knives.

Description

technical field [0001] The present invention relates to a special cutting device. To be precise, the present invention is a method for cutting animal hair fibers (such as wool) along the length direction of the hair bundle to segment and cut fiber fragments of different lengths for testing and researching the fineness and evenness of the wool fibers (along the length direction of the hair bundle). Sampling device for changes in fineness along the length of the tuft. Background technique [0002] In recent years, with the continuous development of the textile industry, the quality requirements for textile raw materials are getting higher and higher, especially the fineness and evenness of wool fiber, which is a bulk wool spinning raw material, has been paid more and more attention by the wool spinning industry. According to research, 80% of the spinnability of wool fiber is determined by its fineness and evenness. The poorer the evenness of the wool pile, the more serious t...

AI Technical Summary

Problems solved by technology

Cut a fiber sample with a Hastelloy slicer, at least two cuts are required, and the number of samples cut each time is limited

In addition, using a Hastelloy slicer to cut samples in sections is easy to mess up the hair bundles, and its operation is difficult, so that the number of sample cuts is limited

Therefore, the current wool fiber fineness test in our country basically cuts a part in the middle of the hair tuft, while the wool tuft evenness test usually only divides the upper, middle and lower three sections to cut the sample, and the position of the cut sample cannot be quantitatively determined

In this way, the representativeness of the sample and the accuracy of the cutting position are poor, thus affecting the accuracy of the test results

It brings difficulties to the research work on the morphology of hair tufts in China

At present, the only international instrument used for evenness testing is the FDA2000 produced in Australia. This instrument uses laser scanning technology and does not need to cut samples to test the fineness of the entire bundle of wool at certain distances along its length. Then analyze its fineness change, but the instrument is expensive and difficult to popularize
