Description

Technical Field

[0001] The utility model relates to the technical field of weaving cloth lench edges, in particular to a lench edge mechanism of a jacquard machine. Background Art

[0002] Jacquard machine, also known as flower machine or flower machine, is a human-powered textile machine equipped with a jacquard mechanism that can raise and lower each warp yarn separately. It can be used to weave complex large-patterned fabrics. It is an important invention in ancient China. The jacquard machine needs to be twisted after work is completed.

[0003] The hemming mechanism of the existing jacquard machine can mostly only perform synchronous adjustment of the distance between the two ends, but the needs for woven cloth are diverse, and different forms of hemming are often required on both sides. The distances required to control different forms of hemming will also be different. Then, it is inconvenient to adjust the hemming mechanism on one side synchronously, and it is often necessary to adjust back and forth, with poor adaptability. In addition, the newly woven cloth needs to be ironed flat to facilitate better hemming, but different types of woven cloth have different thicknesses, making it difficult to achieve better ironing and flatness.

[0004] The Chinese utility model patent with application number CN202223527122.5 proposes a jacquard machine hemming mechanism that is easy to clean. Through the arrangement of the ironing roller and the lint removal roller, the driving motor can drive the ironing roller and the lint removal roller to rotate synchronously through the belt transmission mechanism. The heating tube in the ironing roller will heat the ironing roller, thereby rolling and ironing the cloth flat, and the lint suction mechanism at one end of the lint removal roller can suck away the lint and dust through the lint removal holes on the lint removal roller, so that the cloth remains clean. Although this jacquard machine hemming mechanism that is easy to clean can be ironed flat, it can only be used to iron woven fabrics of fixed thickness, and its practicality is poor. Moreover, it can only be ironed flat on one side, and the flattening effect will also be poor.

[0005] Therefore, a leno mechanism for a jacquard machine is proposed. Utility Model Content

[0027] Specifically, Figure 2 and Figure 4As shown, a slider 8 is fixedly connected to the upper end of the mounting seat 9, and the slider 8 is clamped in the slide rail 7 and slidably connected. The slide rail 7 is opened at the bottom end of the movable seat 6. The slide rail 7 and the slider 8 are both T-shaped. The slide rail 7 and the slider 8 are adapted to each other. A second servo motor 11 is fixedly installed on the side of the mounting seat 9.

The gear 12 is meshed with a rack 13, and the rack 13 is fixedly connected to the bottom end of the movable seat 6. When in use, the first servo motor 4 is started. Because the first bidirectional lead screw 5 is threadedly connected with two symmetrical groups of movable seats 6, and the movable seats 6 are attached to the inside of the support frame 3, the first servo motor 4 drives the two groups of movable seats 6 to move toward or away from each other through the first bidirectional lead screw 5, and the two groups of movable seats 6 drive the two groups of hemming devices 10 to adjust to a suitable distance through the mounting seat 9.
