[0002] In the textile industry, air-jet looms, with their advantages of high-speed weaving, high production efficiency, and stable fabric quality, have become one of the mainstream weaving equipment, widely used in the production and processing of various fabrics such as cotton, chemical fibers, and blends. As a key step in the weaving process of air-jet looms, the selvage operation's core function is to treat the fabric edge. Through a specific selvage mechanism, the warp and weft yarns at the fabric edge are firmly interwoven to form a neat and sturdy selvage structure. This process directly affects the fabric's suitability for subsequent processing, the finished product's appearance, and its durability. This utility model relates to a selvage mechanism for air-jet looms.

[0003] In the sewing mechanism currently used in air-jet looms, the top roller is prone to shaking when the sewing machine is stopped for position adjustment, which in turn causes the fabric to shake, directly affecting the stability of the fabric positioning and ultimately affecting the sewing accuracy.

During the edge twisting process, the drive motor 232 stops, and the first hydraulic cylinder 261 drives the base 263 and the rubber pad 2631 to move down and press the top roller 255 to prevent it from rotating. Then, the third hydraulic cylinder 291 drives the connecting rod 2921 to move down along the linear bearing seat 292, thereby moving the lower pressure plate 293 and the buffer plate 2931. Pressing down on the support rod 294 to stabilize the fabric, then adjusting the position of the edge trimming machine 287, driving the lead screw 275 to slide the mating seat 272 and sliding seat 271 left and right by rotating the handwheel 2751, and driving the lead screw 284 to move the movable seat 285 up and down under the guidance of the fixed rod 282 via the connecting belt, thereby realizing the left and right and height adjustment of the edge trimming machine 287 to accurately align it with the edge of the fabric, starting the edge trimming machine 287 and retracting the first hydraulic cylinder 261 and the third hydraulic cylinder 291, driving the motor 232 to rotate to resume fabric feeding, and starting the fabric edge trimming operation; throughout the process, the controller 141 integrates and controls all driving components.
