Description

Technical Field

[0001] The utility model relates to the technical field of water jet loom leveling equipment, in particular to a large-area leveling device for a water jet loom. Background Art

[0002] The water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. The frictional traction of water jet weft insertion on the weft yarn is greater than that of air jet weft insertion, and the diffusion is small, which is suitable for the weft insertion of synthetic fibers, glass fibers and other filaments with smooth surfaces. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, the jet weft consumes less energy and has the lowest noise. The water jet loom uses water as the weft insertion medium to generate frictional traction on the weft yarn by jetting water, so that the weft yarn on the fixed bobbin is introduced into the shed. The water jet loom has the characteristics of high speed and high unit output, and is mainly suitable for the production of hydrophobic filament chemical fiber fabrics with smooth surfaces. However, since water is used as the weft insertion medium, the obtained grey cloth is wet, and even after dehydration, a small amount of water will remain. It is very easy to produce creases when winding into a cloth roll. When the cloth roll is dried, the creases are more difficult to smooth, affecting the appearance and quality of the product.

[0003] CN102433671A discloses a leveling device for a water jet loom, comprising a cloth pressing roller, characterized in that: a cloth pressing roller belt is respectively provided at both ends of the cloth pressing roller, one end of the cloth pressing roller belt is sleeved with the cloth pressing roller, and the other end of the cloth pressing roller belt is connected to a cloth pressing roller belt seat. The overall structure of the invention is simple and stable, and the cloth pressing roller can adjust itself to the thickness of the cloth roll, thereby ensuring a good leveling effect, saving manpower, and improving product quality.

[0004] In this solution, the cloth pressing roller can play a simple role in smoothing flat cloth, but when dealing with cloth rolls, there will be a problem of offset, making it difficult to apply pressure to the cloth roll, and a good smoothing effect cannot be achieved for the grey cloth of the water jet loom.

[0014] (III) Beneficial effects

[0015] The utility model provides a large-area leveling device for a water jet loom. It has the following beneficial effects:

[0016] 1. The large-area leveling device of the water jet loom is equipped with a leveling mechanism. When the cloth roll moves on the conveyor table, the ironing board will contact the cloth due to the reaction force of the spring, and the nozzle will spray water on the cloth at this time. After spraying water, the two ironing boards can continuously iron the cloth in sequence, so that the cloth can be flat before rolling up, avoiding wrinkles. In addition, the ironing board can play a good role in the cloth made by the water jet loom, and the cloth can be leveled without spraying water.

[0017] 2. The large-area leveling device of the water jet loom is provided with a winding mechanism. The winding roller can rotate to wind the cloth. The wound cloth is wound from the bottom of the winding roller, so that the middle shaft plays an effect of supporting the cloth. Then, when winding, the cloth roll will be pressed by the pressing wheel, so as to ensure the flatness of the winding. When the cloth roll gradually becomes larger, the weight on the winding roller will slowly increase, and then the pressure of the cloth on the middle shaft will continue to increase. Therefore, the larger the cloth roll, the greater the pressure applied to the cloth roll, so as to avoid difficulty in leveling the cloth roll in the later stage. BRIEF DESCRIPTION OF THE DRAWINGS
