Abstract

The invention discloses a device for stretching and cutting two-to-sliver, comprising stretching region and cutting region, where a first main drag head in the snapping region is a fixed drag head fixed on a machine frame, and the rest are sliding drag heads and installed on a slide way in turn, there is a transmission case arranged under the slide way, driving wheels are fixed in the transmission case, corresponding to the main drag heads, one by one, and there are changeable hanging wheels arranged. The invention adopts a form of four-case and six-stage gear transmission, simplifying the transmission structure, lightening the top case, enhancing the mechanism stability, and having the advantages of high transmission accuracy, and small gear return difference, allowing shorter fiber, canceling the spline shaft to make continuous gearing, adjusting screw being safe and clean in the gear box, and better lubricating effect, etc.

Description

technical field [0001] The invention relates to a continuous filament cutting device, in particular to a tow breaking and slitting device for processing chemical fiber tow or chemical fiber slivers into chemical fiber slivers by a direct breaking method. technical background [0002] The stretch-type direct sliver is used to change the chemical fiber tow made of filament into a spinnable chemical fiber sliver made of short fiber in one process. This process includes several steps in which the chemical fiber tow is first elongated and then broken due to the continuous elongation. The processing is mainly polypropylene chemical fiber tow. In addition, polyester, viscose or Kevlar chemical fiber tow is also processed, and the quality of the fiber strips made by the stretching method is high. The stretching machine has one or more stretching zones, one of which is usually designed as a heating zone, and one or more stretching zones. The stretching and break...
