Weft insertion device
Technical Field
The invention relates to a loom, in particular to a weft insertion device of the loom, and belongs to the field of weaving machinery.
Background
With the advancement of society, the weaving technology is more advanced, and the weft insertion system alone is from manual picking to shuttle picking to shuttleless picking, such as a water jet loom, an air jet loom and the like. However, some varieties are deviated, and some of the advanced shuttleless weaving technologies are not suitable for water and soil. For example, thin velour, because the warp is fine, the pile warp has no tension, the flexible rapier loom with the guide rail can hook the weft warp and break the warp, the rigid rapier loom without the guide rail can not bear the tension and break the warp, and the water jet loom is limited by the raw materials and can only use the chemical fiber with hydrophobicity. Air jet looms are not always good at smoothing chemical fibers. Therefore, some factories continue to use shuttle looms for weft insertion weaving, and even some people change the rapier looms into the shuttle looms, so as to meet the requirements of high speed, good quality and light weight.
With the increasingly tense social labor force, people hope to have a better method to solve the weaving bottleneck of thin velour under the situation of higher and higher requirements on the silk surface quality, thereby saving labor force and improving quality.
Research is also ongoing at Lanzhou university of Engineers, Wuhan university of weaving, etc., but improvements are still made on projectile looms, such as electromagnetic weft insertion, for example, bidirectional weft insertion of a projectile, for example, bidirectional weft insertion shuttle clamp with patent number 201410805442.3, but are not suitable for weft insertion modification of shuttle looms.
