Description
Technical Field
[0001] The utility model relates to a novel jacquard and twirled assembly control system, belonging to the field of rapier looms. Background Art
[0002] The leno fabric is centered on the weft yarn, and the two warp yarns are alternately woven and twisted to form a mutually twisted shape, which improves the shape stability of the fabric. The jacquard structure is a structure in which the warp yarns or weft yarns float or sink on the surface of the fabric or interweave in accordance with regular requirements to form patterns or designs. The patterns vary greatly and can enrich the variety of fabrics. In the Chinese invention patent with the authorization announcement number CN106868686B, entitled "A rapier loom for weaving double-layer breathable fabrics", a rapier loom is disclosed, which can realize leno structure and jacquard structure on one device. The rapier loom includes a frame, a warp feeding component, a warp stopping component, a warp guiding component, a weft guiding component, a jacquard component, a reset mechanism, a curling component and a driving component. The frame includes a front frame and a rear frame. The warp feeding component is arranged on the front frame, and the warp guiding component, the weft guiding component, the jacquard component, the reset mechanism and the curling component are arranged on the rear frame. The warp feeding component includes a component for winding and feeding the double-layer breathable fabric. The rapier loom further comprises a first warp beam for the first warp yarn of the air-permeable fabric and a second warp beam for winding the second warp yarn forming a double-layer breathable fabric. The warp-guiding component comprises a plurality of independently moving first warp-guiding components arranged in a row and a plurality of independently moving second warp-guiding components arranged in a row. The first warp-guiding component is located at a station preceding the second warp-guiding component. The first warp-guiding component is used to drive the first warp yarn to form a shed for introducing the weft yarn between the first warp yarns. The second warp-guiding component is used to drive the second warp yarn to form a shed for introducing the weft yarn between the second warp yarns or to form a shed for introducing the weft yarn between the second warp yarns and a unit warp bundle composed of at least two first warp yarns. The rapier loom further comprises a yarn-splitting component located at a station preceding the yarn-splitting component. The yarn-splitting component is used to separate the horizontal positions of the first warp yarn a and the second warp yarn b, and ensure that the horizontal position of the second warp yarn b when not forming a shed with the unit warp bundle is always lower than the horizontal position of the first warp yarn a. The yarn-splitting fabric comprises a yarn-pressing roller for pressing down the second warp yarn b, with the first warp yarn a above the yarn-pressing roller. If the second warp yarn and the first warp yarn are in the same bundle during the transportation process, that is, the horizontal heights are almost the same, when a part of the second warp yarn is twisted with a part of the first warp yarn to form the first shed, the next adjacent part of the second warp yarn, that is, the second warp yarn itself, will be fully raised, and the next adjacent part of the first warp yarn, that is, the first warp yarn itself, will be fully raised by the second warp yarn. Then, when it is necessary to form a second shed after the first shed, the horizontal position of the first warp yarn has been affected and raised, making it difficult for the second warp yarn to change its relative height accurately with the first warp yarn, and making it difficult for the second warp yarn to appear alternately on the opposite sides of the first warp yarn, which makes it difficult to form the second shed. If the horizontal position of the second warp yarn during transportation is higher than that of the first warp yarn, it will also make it difficult to form the second shed.Therefore, this weaving structure on the rapier loom is specially designed with a yarn dividing cloth to control the horizontal position of the first warp yarn and the second warp yarn to ensure that the shed can be formed normally and accurately when the first warp yarn and the second warp yarn are twisted.
[0003] A yarn separation roller is used to control the horizontal position of the first warp yarn and the second warp yarn. The separation gap between each first warp yarn and the second warp yarn is fixed. When the separation gap needs to be adjusted for different yarns and fabrics, it is troublesome to replace the yarn separation roller. In addition, the existing structure also makes it difficult to control the first warp yarn and the second warp yarn in different areas.
[0004] Based on the above issues, the applicant conducted research, which led to the present case. Utility Model Content
[0005] The utility model aims to provide a novel jacquard and leash assembly control system with more flexible position control of the first warp yarn and the second warp yarn.

The upper and lower positions of the yarn guides can be controlled by the first pulling mechanism and the first reset mechanism, thereby separating the horizontal positions of the first warp yarn and the second warp yarn. Since the positions of the first yarn and the second yarn can be individually controlled through the yarn guides, mutual interference between the yarns is avoided, and the control of a single yarn is more flexible and accurate, meeting the weaving requirements of special fabrics.

[0027] The first, second, and third lifting mechanisms of the present invention are all jacquard faucets 50, which utilize the corresponding drive mechanisms in the existing jacquard faucets 50 to respectively control the lifting of the heald, the left heald arm, the right heald arm, and the yarn guide 31. The first, second, and third resetting mechanisms 32, 22, 21, and fourth resetting mechanisms of the present invention are all springs, which respectively control the downward resetting of the left heald arm, the right heald arm, the middle half heald, and the yarn guide 31 through multiple springs. When the present invention is in use, the first warp yarn 41 can be passed through the yarn guide 31 and then through the first warp guide component 10, and the second warp yarn 42 can be passed through the yarn guide 31 and then through the middle half heald. The yarn guide 31 can more flexibly control the horizontal positions of the first and second warp yarns 41 and 42, so that the first and second warp yarns 41 and 42 are in a better weaving position, thereby improving the stability of the weaving.
