本发明属于纺织机械技术领域，特别是涉及一种角度可调的异形机织物卷取装置及卷取方法。The invention belongs to the technical field of textile machinery, in particular to an angle-adjustable special-shaped woven fabric winding device and winding method.
背景技术Background technique
随着工程技术和材料科学的迅速发展，工业生产对材料性能的要求也变的越来越高。纤维增强复合材料因其独特、卓越的性能，在航空航天、风力发电、船舶等领域特别是飞机制造业中得到广泛应用。采用碳纤维、石英纤维、玻璃纤维等高性能纤维机织成型的机织布，常通过特定形状的裁剪，用于复杂异型面构件的铺层，再经过复合后形成复合材料构件。但是，采用机织布铺放的异型构件，纤维层不连续、纤维走向可设计性不强、存在布层搭接、褶皱等缺陷、材料浪费多，对于航空、航天等领域一些要求承载能力要求较高的构件，其性能无法满足。With the rapid development of engineering technology and material science, industrial production has higher and higher requirements on material performance. Fiber-reinforced composite materials are widely used in aerospace, wind power generation, shipbuilding and other fields, especially aircraft manufacturing, because of their unique and excellent performance. Woven fabrics made of high-performance fibers such as carbon fibers, quartz fibers, and glass fibers are often cut in specific shapes to lay layers of complex shaped surface components, and then composited to form composite material components. However, the special-shaped components laid by woven fabrics have discontinuous fiber layers, poor designability of fiber directions, defects such as overlapping of cloth layers and wrinkles, and a lot of waste of materials. Higher components, its performance cannot meet.
一些需要高性能纤维复合材料的异形构件，其型面多为空间不可展曲面，采用普通矩形机织布进行包裹、缠绕，同样存在布层褶皱、纤维滑移等缺陷，无法满足材料的性能需求。因此，采用仿形机织的工艺，根据型面要求，进行纤维增强体织物的整体织造，所织造的织物具有纤维连续、按材料要求设计纤维走向、包裹后型面贴敷精度高等特点。在仿形机织工艺是在传统机织的工艺上发展而来，主要由送经、开口、引纬、打纬及卷取五大运动构成。其中，为了实现空间曲面的仿形织造，通过仿形模具进行卷取是关键，在进行织造的同时进行仿形包覆及收卷，实现织物型面的精度控制。Some special-shaped components that require high-performance fiber composite materials, most of which are curved surfaces that cannot be developed in space, are wrapped and wound with ordinary rectangular woven fabrics, which also have defects such as fabric folds and fiber slippage, which cannot meet the performance requirements of the material . Therefore, the process of profile weaving is used to weave the fiber reinforced fabric as a whole according to the requirements of the profile. The woven fabric has the characteristics of continuous fiber, fiber direction design according to material requirements, and high precision of profile application after wrapping. The profiling weaving process is developed from the traditional weaving process, which mainly consists of five major movements: warp let-off, shedding, weft insertion, beating-up and take-up. Among them, in order to realize the profiling weaving of the space curved surface, it is the key to take up through the profiling mold, and the profiling wrapping and winding are performed at the same time as weaving, so as to realize the precision control of the fabric profile.
公开号：CN1194126C的一种机织物及其织造方法，介绍了一种非矩形形状如扇形机织物的织造方法，其中介绍了采用仿形模具进行卷取，但是采用其他方法进行织造，仿形模具轴线与织造平面进行平行安装，仿形模具与织造平面会形成一定的角度，在织造中会出现经纱的滑移，造成织物密度不均。该专利为解决滑移问题，采用辅助导辊进行纤维的限位，其结构复杂不同型面的织物需进行辅助导辊的调整及专用设计更换，操作复杂，卷取装置专用性高。这类卷取方法通过变截面模具和辅助压辊可实现异形织物的成形卷取，但是针对不规则织物，无法实现沿母线方向卷取，且卷取角度不可调。公开号：CN211145164U，介绍一种万向联轴器，该万向联轴器主要由可伸缩连杆、万向节组成，实现不在同一轴线或轴线折角较大运动机构的万向传动。公开号CN200978895Y介绍一种十字槽式万向联轴器，该万向联轴器允许的轴线折角大、运行可靠性高、结构简单。这类万向传动结构主要用于力矩和运动的传递，没有应用于异形机织物的卷取装置。公开号CN108396444B，介绍了一种异步多辊卷取机构，该机构主要实现立体织物不同织物层的异步卷取，解决了传统单辊卷取机构造成织物织口向织机机后退缩问题。公开号：CN203284573U，介绍了一种管状立体织机的牵引机构，克服了辊筒式牵引机构对立体织物的碾压，避免立体织物褶痕的产生。Publication number: CN1194126C, a kind of woven fabric and its weaving method, introduces a weaving method of non-rectangular shape such as fan-shaped woven fabric, which introduces the use of profiling dies for coiling, but uses other methods for weaving, profiling dies The axis is installed parallel to the weaving plane, and the profiling mold and the weaving plane will form a certain angle, and warp yarns will slip during weaving, resulting in uneven fabric density. In order to solve the problem of slippage, this patent uses auxiliary guide rollers to limit the position of fibers. Fabrics with complex structures and different profiles need to adjust the auxiliary guide rollers and replace them with special designs. The operation is complicated and the take-up device is highly specific. This kind of winding method can realize the forming and winding of special-shaped fabrics through variable-section dies and auxiliary pressing rollers, but for irregular fabrics, it cannot realize winding along the direction of the generatrix, and the winding angle cannot be adjusted. Publication number: CN211145164U, introduces a universal joint, which is mainly composed of a telescopic connecting rod and a universal joint, and realizes the universal transmission of a motion mechanism that is not on the same axis or the axis has a large kink angle. Publication No. CN200978895Y introduces a cross-groove universal joint, which allows a large axis kink angle, high operational reliability and simple structure. This kind of universal transmission structure is mainly used for the transmission of torque and motion, and is not applied to the take-up device of special-shaped woven fabrics. Publication No. CN108396444B introduces an asynchronous multi-roller take-up mechanism, which mainly realizes the asynchronous take-up of different fabric layers of three-dimensional fabrics, and solves the problem that the fabric mouth shrinks toward the back of the loom caused by the traditional single-roller take-up mechanism. Publication number: CN203284573U, introduces a traction mechanism of a tubular three-dimensional loom, overcomes the rolling of the three-dimensional fabric by the roller-type traction mechanism, and avoids the generation of three-dimensional fabric creases.
本发明提出了一种角度可调的异形机织物卷取装置，可实现卷取平面内一定角度任意调节，实现织物沿母线方向卷取，保障经纱张力均匀性、减少纱线滑移。The invention proposes an angle-adjustable special-shaped woven fabric take-up device, which can realize arbitrary adjustment of a certain angle in the take-up plane, realize fabric take-up along the generatrix direction, ensure warp tension uniformity, and reduce yarn slippage.

After the loom is used to open the warp yarn, weft insertion and beating-up, the take-up shaft is driven to rotate by a certain angle through the driving mechanism to realize the profiling take-up of the formed fabric. Since the warp is tangent to the parallel generatrix of the take-up die, there is no warp slippage. After the fabric taken up by the take-up shaft wraps the tapered take-up mold for one week, the take-up step is automatically adjusted through the control program to achieve stable control of the weft density.
本发明工作流程与原理如下：一些需要高性能纤维复合材料的异形构件，其型面多为空间不可展曲面，所以无法通过平面板块织物组合拼接成空间曲面。本申请装置主要实现异形织物编织过程中仿形成形及卷取两种功能。织物成型过程中，随着织物卷取的厚度不断增加，异形卷取模具和织物相切的母线也在不断变化，为了保证编织过程织物经、纬密的均匀性，本装置使得异形卷取模具和织物相切的角度会随着织物的卷取厚度变化而变化，本装置的夹角a会在编织过程中调整变化(如图5所示)，本装置也会随着织物厚度的增加调整异形卷取模具的位置，保证织物母线和模具的仿形相切，减少经纱在模具卷取时滑移现象，从而控制织物的经纬密均匀性。The working process and principle of the present invention are as follows: Some special-shaped components that require high-performance fiber composite materials are mostly curved surfaces that cannot be developed in space, so they cannot be spliced into curved surfaces in space by combining flat plate fabrics. The device of the application mainly realizes two functions of profiling and coiling during the weaving process of special-shaped fabrics. During the fabric forming process, as the thickness of the fabric coiling continues to increase, the tangent generatrices between the special-shaped coiling mold and the fabric are also constantly changing. In order to ensure the uniformity of the fabric warp and weft density during the weaving process, this device makes the special-shaped coiling mold The angle tangent to the fabric will change with the thickness of the fabric, and the angle a of the device will be adjusted during the weaving process (as shown in Figure 5), and the device will also be adjusted as the thickness of the fabric increases. The position of the special-shaped winding mold ensures that the profiling of the fabric generatrix and the mold is tangent, and reduces the slippage of the warp yarn during the mold winding, thereby controlling the uniformity of the warp and weft density of the fabric.
如图6所示，根据分析异形织物成型过程中织物母线的变化规律，织物成型过程中，随着织物的卷取，模具的厚度不断增加，模具的母线位置规律变化，通过控制系统控制两侧升降机构1的升降驱动装置的动作，实现两侧升降机构1分别按控制编程规律升降，从而实现异形卷取模具5倾斜角度的规律变化，控制异形卷取模具5母线和平面织物的仿形相切(如图7所示)。异形卷取模具5位置调节的同时驱动机构2通过万向转向机构4带动异形卷取模具5对织物进行收卷。As shown in Figure 6, according to the analysis of the change law of the fabric busbar during the forming process of the special-shaped fabric, during the fabric forming process, as the fabric is taken up, the thickness of the mold continues to increase, and the position of the busbar of the mold changes regularly. The two sides are controlled by the control system The action of the lifting drive device of the lifting mechanism 1 realizes the lifting and lowering of the lifting mechanisms 1 on both sides according to the control programming law, thereby realizing the regular change of the inclination angle of the special-shaped
如图8所示，一种角度可调的异形机织物卷取方法，包括以下步骤：As shown in Figure 8, a kind of angle-adjustable profiled woven fabric winding method comprises the following steps:
步骤1、调整异形卷取模具在卷取轴上的位置，保证卷取中心位置与织造中心对正；Step 1. Adjust the position of the special-shaped coiling mold on the coiling shaft to ensure that the coiling center is aligned with the weaving center;
步骤2、驱动机构通过带动连接轴旋转，进而带动卷取轴上的异形卷取模具进行旋转，实现异形机织物的仿形卷取；
步骤3、通过独立调整两侧升降机构的高度，调整卷取轴和异形卷取模具的轴线与织造平面的夹角，使得织物母线和异形卷取模具的仿形一直保持相切。
