Length measuring and weft accumulating device used on water-jet loom

Abstract

The invention relates to a length measuring and weft accumulating device used on a water-jet loom. The device comprises a controller and a weft accumulating device, wherein the weft accumulating device comprises a motor, a base and rollers; the rollers are arranged on the base along the circumferential direction; an inclination angle is formed between the shaft of each roller and the vertical line of an installation plane of the base; and the rollers comprise a driven roller driven by the motor. In the device, the rollers are obliquely arranged, so that appropriate intervals exist among circles of wefts accumulated on the rollers, and the wefts cannot be overlapped and wound; moreover, the driven roller is obliquely arranged, so that the wefts are output in a pulse mode, the unwinding length of the wefts is stably controlled, and shutdown obstacle removal times is reduced; therefore, work efficiency is improved, and the quality of fabrics is ensured correspondingly.

Description

technical field [0001] The invention relates to a textile machine, in particular to a length-measuring weft feeder used on a water-jet loom. Background technique [0002] When the water jet loom is weaving, it uses high-speed water flow with a certain pressure to drive the weft thread to achieve beating. Before weft beating, weft insertion needs to be carried out by a weft feeder. The length-measuring weft feeder is used as a weft yarn feeding device to control the storage and release of weft yarns. In the prior art, the weft insertion device usually includes a motor, a rotating arm and a yarn storage drum. The weft thread enters one end of the rotating arm, and the motor drives the rotating arm to rotate, so that the weft thread is wound on the yarn storage drum, and the yarn storage drum is positioned by a magnet. When the weft thread is sprayed, the weft thread on the storage drum is unwound and enters the fabric fall through the nozzle. The yarn storage method of thi...

AI Technical Summary

Problems solved by technology

The yarn storage method of this kind of weft feeder is not easy to grasp the winding angle of the weft thread, and the phenomenon of overlapping and winding of the weft thread often occurs

When sharing weal and woe, the weft threads are tightly wound and arranged, and it is easy to cause several laps of weft threads to fall off at the same time during weft insertion, which will affect the normal work, reduce the working efficiency of the loom, and easily cause fabric defects
