[0016] As shown in Fig. 1, the double-needle plate roller hybrid stretch-cutting spinning equipment used in the stretch-cutting process of the present invention is provided with three stretch-cut zones. The sliver A after softening enters the third stretching zone, the second stretching zone and the first stretching zone successively, and is stretched respectively in these stretching zones to make the fibers straight and parallel, and the long fibers follow With the gradual reduction of the distance in the stretch-cutting area, it is gradually broken into the required length, which ensures the elimination of ultra-long fibers. At the same time, due to the function of the needle plate, it can greatly reduce the mutual binding (bonding) of fibers , that is to reduce the doubling, and the curved fiber bundles ...

Abstract

The invention relates to a double needle plate roller composite draft-cut spinning device, which comprises a roller type draft-cut device (2) and two needle plat devices (3) which are fixed on the rack, wherein the roller type draft-cut device (2) comprises three draft-cut areas which are formed by four rubber rollers and four pairs of rollers, and the needle plat devices (3) are respectively arranged on the first and the third draft-cur areas. The invention can distinctively reduce doubling, and guarantee that bend fiber bundles which are shorter than the first and the third draft-cut gauge can be straightened under the control of needle bar.

Description

technical field [0001] The invention belongs to the field of roller mixed stretch-cut spinning equipment, in particular to a double-needle plate roller mixed stretch-cut spinning equipment. Background technique [0002] In the current roller mixed stretch-cut spinning equipment, such as the invention patent of application number 200510110059.7 roller-needle plate mixed stretch-cut spinning equipment for ramie, there are five pairs of top rollers, which are divided into 4 stretch-cut zones, and only in the last Needle boards are installed in the fourth stretching area, and there are many parallel threads. In particular, because the length of partially bent and entangled fiber bundles is shorter than that of the first stretching area, it cannot be gripped by the rollers and cannot be stretched. After the processing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-needle plate roller hybrid stretch-cut...
