Technical Field
The invention belongs to the technical field of textile equipment, and particularly relates to a weft yarn traction device of a flat laying machine and a corresponding weft yarn traction method.
Background
The flat laying machine is an advanced textile machine in the world at present, and the main principle is that yarns in longitudinal and transverse directions are converged together, cross points are bonded through resin adhesive, and the cross points are heated and dried for positioning. The machine is mainly different from the domestic most common rapier loom, and the production efficiency of the flat laying machine can be improved by 30-50 times.
The weft yarn traction of the prior spreading machine is mainly in a rotating mode, and the main defects of the rotary weft yarn spreading device are as follows:
1. the rotating device has a complex structure and occupies a large area.
2. The rotating device has higher yarn removing ratio, unstable lapping effect and longer occupied time for replacing the yarns.
3. The rotating device has very high requirements on the sleeve because the rotating speed of the weft yarn sleeve is relatively high, so that the specification of the yarn is limited, and the specification cannot be conveniently changed.
4. The quality of the product produced by the rotating device is unstable, and the density of the weft yarn is not uniform.
To solve the problems in the related art, no effective solution is proposed at present, and for this purpose, a weft yarn traction device of a spreader and a corresponding weft yarn traction method are proposed.
