Description

Technical Field

[0001] The utility model relates to the technical field of air-jet fabrics, and more specifically to a guide roller for an air-jet loom. Background Art

[0002] The air jet loom is a shuttleless loom that uses a jet of air to pull the weft yarn through the shed. Its working principle is to use air as the weft insertion medium, and use the ejected compressed air flow to generate friction traction on the weft yarn to pull the weft yarn through the shed, and achieve the purpose of weft insertion through the jet generated by the air jet.

[0003] The utility model patent with publication number CN219342462U discloses a guide roller of an air jet loom. The existing guide rollers of air jet looms are mostly installed through bearing seats during installation, which may make it inconvenient to install or replace the guide rollers; and the existing guide rollers are not convenient for flattening the fabric during use, which may cause wrinkles in the fabric, reducing the practicality of the guide rollers. The above utility model has two sets of spiral grooves symmetrically arranged, so that when the guide roller body rotates, the fabric is expanded outward along the spiral direction of the spiral groove, thereby playing a role in flattening the fabric and preventing the fabric from wrinkling.

[0004] However, in actual use, when replacing a faulty guide roller, the bearings cannot be quickly removed from both sides of the guide roller, which affects the replacement efficiency.
