Embodiment 1

[0028] In view of the above-mentioned problems, the present invention provides a preferred embodiment, this scheme relates to a kind of carding device, described carding device comprises symmetrically arranged front carding device and rear carding device, and described front carding device is consistent with described rear carding device , and are respectively arranged on the front side and the rear side of the reinforcing point, and the fiber strips on the front side and the rear side of the reinforcing point are combed. The specific structure of the front and back carding device is as follows:

[0029] The preceding carding device includes an upper carding roller and a lower carding roller, the upper carding roller is positioned at the top of the fiber strip, and the upper carding roller includes an upper dense carding roller and an upper sparse carding roller, and the upper dense carding roller passes through the first The upper lifting device is connected with the upper te...

Abstract

The invention relates to a method for testing the intrinsic quality of a sliver. The invention tests the front and rear fiber strips, the fiber quality of the front and rear ends, and the change of the mass distribution of the front and rear fiber strips along the length direction of the support point, which is the theoretical mass distribution before drawing. Curve and front actual mass distribution curve, the area of ​​the graph composed of the two curves is the front hook index, after drawing the theoretical mass distribution curve and the rear actual mass distribution curve, the area of ​​the graph composed of the two curves is the back hook index, so Realize the test of the internal quality of the sliver; at the same time, the present invention provides a carding device, which sequentially carries out the upper and lower simultaneous carding stage, the lower carding stage and the upper carding stage for the fiber sliver that is intercepted and supported in the middle. The fibers are combed out, and on the other hand, the fibers supported by the blessing points and containing hooks are combed and straightened.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for testing the internal quality of sliver and a carding device thereof. Background technique [0002] At present, in the spinning process, firstly, the larger fiber blocks that are disordered and contain more impurities are opened and removed to form fiber bundles or fiber rolls with a certain degree of uniformity, and then the fiber bundles or The fiber rolls are carefully and deeply opened and removed to make the initial fiber strips. At this time, the fibers in the fiber strips are in a poor straight state, and the fibers of the fiber strips are mostly at the front or rear, or at the front and rear ends. Both contain hooks, and then the fiber strips are combed and drawn, or directly drawn, which improves the straightness of the fibers in the sliver on the one hand, and improves the weight unevenness in the length direction on the other hand. , so as to ...
