Abstract
Description
Technical Field
[0001] This utility model relates to the field of air-jet loom technology, specifically to an automatic selvedge mechanism for polyester fabric on 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. The working principle is to use air as the weft-introducing medium, and the compressed airflow generated by the jet will generate frictional traction force on the weft yarn to pull it through the shed. The jet generated by the airflow achieves the purpose of weft introduction.
[0003] Among several shuttleless looms, the air-jet loom has the highest speed. Due to its reasonable weft insertion method, high weft insertion rate, simple and safe operation, wide adaptability to various products, low material consumption, high efficiency, high speed and low noise, it has become one of the most promising new types of looms. However, the biggest disadvantage of the air-jet loom, which uses airflow weft insertion, is its high energy consumption.
[0004] However, existing technologies reveal that traditional air-jet looms, during selvage operations, do not facilitate rapid adjustment of the guide rods that guide the textile yarn. The adjustment process is cumbersome and laborious. This application addresses this problem by incorporating components such as a worm gear, worm wheel, bevel gear one, and bevel gear two. The connection between bevel gear one and bevel gear two enables the connection between the threaded rod and the sliding block, allowing the two sets of guide rods to move relative to each other. This facilitates rapid adjustment of the distance between the guide rods, improving tension and ensuring the yarn tension meets weaving requirements. Therefore, a new solution is needed to address this issue. Utility Model Content
[0005] The existing technology mentioned above has the shortcomings and defects of not being able to quickly adjust the guide rod that guides the textile yarn, the adjustment operation is cumbersome, and the debugging is laborious.
[0006] This utility model discloses an automatic selvedge mechanism for polyester fabric on an air-jet loom, comprising a worm gear, a worm wheel meshing on the outer surface of the worm gear, a connecting rod fixedly connected to the inner wall of the worm wheel, a bevel gear I fixedly connected to the bottom end of the connecting rod, two bevel gear II meshing on the outer surface of the bevel gear I, a threaded rod fixedly connected to the side of each bevel gear II that is far apart from each other, a sliding block threadedly connected to the outer surface of each threaded rod, a mounting plate fixedly connected to the bottom surface of each sliding block, mounting bases arranged at equal intervals fixedly connected to the front surface of each mounting plate, and a guide rod fixedly connected to the front surface of each mounting base.
[0007] Furthermore, the outer surface of the worm gear is rotatably connected to a mounting component, the bottom surface of the mounting component is fixedly connected to a mounting block, and the outer surface of the connecting rod is rotatably connected to the inner wall of the mounting block.
[0008] Furthermore, the bottom surface of the mounting block is provided with a sliding groove, and the outer surface of each sliding block is slidably connected to the inner wall of the sliding groove. A connector is fixedly installed on the right side of the mounting block.
[0009] Furthermore, a support rod is fixedly connected to the left side of the connector, and a hemming module is fixedly installed on the left side of the support rod.
[0010] Furthermore, a guide block is fixedly connected to the bottom surface of the twisting module, and a threaded block is fixedly connected to the back side of the guide block.
[0011] Furthermore, the inner wall of the threaded block is threaded with a screw, and the outer surface of the screw is rotatably connected to two limiting blocks.
[0012] Furthermore, the inner wall of the guide block is slidably connected with a slide rail, and the front of each limiting block is fixedly connected to the back of the slide rail.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model incorporates components such as a worm gear, worm wheel, bevel gear one, bevel gear two, threaded rod, and sliding block. Rotating the worm gear causes the worm wheel to rotate, which in turn drives the connecting rod. The connecting rod then connects bevel gear one and bevel gear two, causing them to rotate synchronously in opposite directions. These bevel gears then drive the corresponding threaded rod to rotate, which in turn connects to the sliding block, causing the two sliding blocks to move synchronously. This, in turn, drives the mounting plate mounted on the bottom surface. The mounting plate then moves the corresponding mounting base and guide rod, facilitating adjustment of the distance between the two sets of guide rods and thus the tension, ensuring the yarn tension meets weaving requirements.
[0015] 2. This utility model incorporates components such as a guide block, threaded block, screw, limiting block, and slide rail. The slide rail is fixed with bolts. Rotating the screw, the limiting block limits its movement. The connection between the screw and the threaded block allows the threaded block to slide on the surface of the slide rail, thereby moving the twisted edge module mounted on the guide block. This facilitates adjustment of the twisted edge module's position. The installation of support rods and connectors enables the movement of the mounting block, thus achieving the effect of easily adjusting the position of the twisted edge module.
