Problems solved by technology

[0002] The rapier loom is currently the most widely used shuttleless loom. In addition to the characteristics of high speed, high degree of automation, and high-efficiency production of the shuttleless loom, its positive weft insertion method has strong variety adaptability and can adapt to Weft insertion of various yarns, and rapier looms also have obvious advantages in multi-color weft weaving; as shuttleless looms replace shuttle looms, rapier looms will become the main production machine for woven fabrics ;The weft selection mechanism is an important unit in the rapier loom. The existing weft selection mechanism generally has the disadvantages of limited weft selection, poor clamping effect of the rapier chuck, and large running resistance.

Abstract

The invention discloses a weft selecting mechanism for big tows. The mechanism includes a rapier clamping head and a multi-selection turntable; the multi-selection turntable is provided with multipleyarn guiding channels which can run through big tow fibers; by rotating the multi-selection turntable, the yarn discharging end of each yarn guiding channel can correspond to a clamping part of the rapier clamping head in sequence; a motor is adopted for locating, and conversion of the tows is fast and accurate.

Description

technical field [0001] The invention belongs to the field of looms, in particular to a weft selection mechanism for large tows. Background technique [0002] The rapier loom is currently the most widely used shuttleless loom. In addition to the characteristics of high speed, high degree of automation, and high-efficiency production of the shuttleless loom, its positive weft insertion method has strong variety adaptability and can adapt to Weft insertion of various yarns, and rapier looms also have obvious advantages in multi-color weft weaving; as shuttleless looms replace shuttle looms, rapier looms will become the main production machine for woven fabrics ; The weft selection mechanism is an important unit in the rapier loom. The existing weft selection mechanism generally has the disadvantages of limited weft selection, poor clamping effect of the rapier chuck, and large running resistance. Contents of the invention [0003] Purpose of the invention: In order to overco...
