Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary components for air-jet looms, specifically a guide roller for an air-jet loom. Background Technology

[0002] Air-jet looms are shuttleless looms that use jet airflow to pull the weft yarn through the shed. During the weaving process, guide rollers are key transmission and guiding components, mainly used to transport, tension and guide the warp yarns or fabric, ensuring that the yarns or fabrics maintain a stable running trajectory during the weaving process and guaranteeing the weaving quality of the fabric.

[0003] The guide rollers of existing air-jet looms are mostly integrated and fixed structures, which have the following drawbacks: Firstly, the length of the guide rollers is fixed and cannot be adjusted according to the weaving width of the air-jet loom or the feeding requirements of the yarn and fabric. This limits their applicability. When different weaving specifications need to be adapted, the entire guide roller must be replaced, increasing equipment costs and replacement time. Secondly, after long-term use, the surface of the guide rollers easily accumulates impurities such as fly waste and oil stains. If not cleaned in time, these impurities will adhere to the surface of the yarn or fabric, causing fabric defects. Cleaning existing guide rollers requires manual disassembly and cleaning after the machine is stopped, which is cumbersome and affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a guide roller for an air-jet loom to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a guide roller for an air-jet loom, comprising a fixed shaft, both ends of which are provided with mounting flanges, the mounting flanges being provided with mounting holes, two symmetrical movable rollers being movably sleeved on the outer wall of the fixed shaft, the inner walls of the two movable rollers being provided with locking components, and the opposite ends of the two movable rollers being provided with annular bosses.

[0006] Preferably, guide grooves are provided on both sides of the fixed shaft along the axial direction, and multiple equidistant positioning holes are provided inside the guide grooves. The locking assembly includes guide sliders and locking bolts. Guide sliders are provided on both sides of the inner wall of the movable roller. The guide sliders on both sides are slidably disposed in the corresponding guide grooves. Locking bolts are installed on the internal threads of the guide sliders. The positioning holes allow one end of the locking bolt to be inserted.

[0007] Preferably, four mounting holes are provided, and the four mounting holes are equidistantly distributed along the periphery of the mounting flange.

[0008] Preferably, a cleaning ring is provided on the outside of the movable roller, and a cleaning brush is provided on the inner wall of the cleaning ring, with one end of the cleaning brush in contact with the outside of the movable roller.

[0009] Preferably, four cleaning brushes are provided, and the four cleaning brushes are arranged in a circular array about the center of the cleaning ring.

[0010] Preferably, the cleaning ring has connecting ears on both sides of its top, and a fixing rod passes through each of the connecting ears.

[0011] Preferably, the fixed shaft is made of 45 steel, and the surface of the fixed shaft has been heat-treated to improve its strength and wear resistance.

[0012] Preferably, the movable roller is made of aluminum alloy, and the inner wall of the movable roller is fixed to the guide slider by welding to ensure connection strength.

[0013] Preferably, the cleaning brush is made of nylon filaments with a diameter of 0.1-0.2mm, which ensures cleaning effectiveness without scratching the surface of the moving roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The movable rollers slide in a guide groove on the fixed shaft via a guide slider. The distance between the two movable rollers can be adjusted according to the weaving width of the air-jet loom or the conveying requirements of the yarn fabric. The position is then locked by locking bolts and positioning holes. There is no need to replace the entire guide roller, which expands the scope of application and reduces equipment costs.

[0015] 2. The cleaning brushes on the inner wall of the fixed cleaning ring fit tightly against the rotating movable roller, which can clean the surface of the guide roller after the guide roller has finished working, such as fly shavings and oil stains, ensuring the cleanliness of the guide roller surface, reducing the generation of fabric defects, and improving production efficiency.
