Description

Technical Field

[0001] The invention belongs to the technical field of textile machinery, and in particular relates to a winding device and a winding method for special-shaped woven fabrics with adjustable angles. Background Art

[0002] With the rapid development of engineering technology and materials science, the requirements for material performance in industrial production have become increasingly higher. Fiber-reinforced composite materials have been widely used in aerospace, wind power generation, shipbuilding and other fields, especially in the aircraft manufacturing industry, due to their unique and excellent performance. Woven fabrics made of high-performance fibers such as carbon fiber, quartz fiber, and glass fiber are often cut into specific shapes and used for the laying of complex special-shaped surface components, and then compounded to form composite components. However, special-shaped components laid with woven fabrics have discontinuous fiber layers, weak designability of fiber orientation, defects such as overlap of fabric layers and wrinkles, and much material waste. Their performance cannot meet the requirements of some components with high load-bearing capacity in the fields of aviation and aerospace.

[0003] Some special-shaped components that require high-performance fiber composite materials have surfaces that are mostly non-developable in space. Ordinary rectangular woven fabrics are used for wrapping and winding, which also has defects such as cloth layer wrinkles and fiber slippage, and cannot meet the performance requirements of the material. Therefore, the process of contour weaving is adopted to weave the fiber-reinforced fabric as a whole according to the surface requirements. The woven fabric has the characteristics of continuous fibers, fiber orientation designed according to material requirements, and high surface application accuracy after wrapping. The contour weaving process is developed based on the traditional weaving process, and is mainly composed of five major movements: warp feeding, opening, weft insertion, weft beating and winding. Among them, in order to achieve contour weaving of spatial surfaces, winding through contour molds is the key. Contour coating and winding are carried out while weaving to achieve precision control of the fabric surface.

[0004] Publication number: CN1194126C, a woven fabric and its weaving method, introduces a weaving method of non-rectangular shaped woven fabrics such as fan-shaped woven fabrics, wherein the use of a profiling mold for winding is introduced, but when other methods are used for weaving, the axis of the profiling mold is installed parallel to the weaving plane, and the profiling mold and the weaving plane will form a certain angle, and the warp yarn will slip during weaving, resulting in uneven fabric density. In order to solve the slip problem, this patent uses auxiliary guide rollers to limit the fiber position. The structure is complex, and fabrics with different profiles need to adjust the auxiliary guide rollers and specially designed replacements. The operation is complicated, and the winding device is highly specialized. This type of winding method can realize the forming and winding of special-shaped fabrics through variable-section molds and auxiliary pressure rollers, but for irregular fabrics, it is impossible to achieve winding along the generatrix direction, and the winding angle is not adjustable. Publication number: CN211145164U, introduces a universal coupling, which is mainly composed of a telescopic connecting rod and a universal joint, and realizes the universal transmission of motion mechanisms that are not on the same axis or have a large axis angle. Publication number CN200978895Y introduces a cross-slot universal coupling, which allows a large axis angle, has high operational reliability and a simple structure. This type of universal transmission structure is mainly used for the transmission of torque and motion, and is not applied to winding devices for special-shaped woven fabrics. Publication number CN108396444B introduces an asynchronous multi-roller winding mechanism, which mainly realizes the asynchronous winding of different fabric layers of three-dimensional fabrics, and solves the problem of the fabric weft retreating to the back of the loom caused by the traditional single-roller winding mechanism. Publication number: CN203284573U introduces a traction mechanism for a tubular three-dimensional loom, which overcomes the rolling of the three-dimensional fabric by the roller traction mechanism and avoids the generation of folds on the three-dimensional fabric.

[0005] The invention proposes an angle-adjustable special-shaped woven fabric winding device, which can realize arbitrary adjustment of a certain angle in a winding plane, realize the winding of the fabric along the generatrix direction, ensure the uniformity of warp tension and reduce yarn slippage.

[0015] Furthermore, the universal steering mechanism includes a left universal joint, an extension mechanism, a locking mechanism, and a right universal joint; one end of the left universal joint is connected to the lifting mechanism on the left, and the right universal joint is connected to the lifting mechanism on the right; the other end of the left universal joint is connected to the extension mechanism, and the extension mechanism can be extended and locked, and the extension distance is adjusted according to the inclination angle of the special-shaped winding mold; a winding shaft is arranged between the end of the extension mechanism away from the left universal joint and the right universal joint, and a special-shaped winding mold is arranged on the winding shaft; locking mechanisms are arranged at both ends of the special-shaped winding mold, and the special-shaped winding mold is locked on the winding shaft through the locking mechanism after the position is adjusted according to the distribution range of the warp yarn, and the locking mechanism and the special-shaped winding mold are rigidly connected through a mechanical structure to ensure that the special-shaped winding mold and the universal steering mechanism rotate synchronously.

[0016] Furthermore, the driving mechanism is driven by a motor, which is connected to the connecting shaft of the universal steering mechanism through a plum blossom coupling after passing through a reducer, and the connecting shaft is fixed on the slider by cooperating with a bearing.

[0017] In order to achieve the purpose of the present invention, the present invention also discloses a method for winding a special-shaped woven fabric with adjustable angle, comprising the following steps:

[0018] Step 1: Adjust the position of the special-shaped winding mold on the winding shaft to ensure that the winding center is aligned with the weaving center;

[0019] Step 2, the driving mechanism drives the connecting shaft to rotate, thereby driving the special-shaped winding mold on the winding shaft to rotate, so as to realize the contoured winding of the special-shaped woven fabric;

[0020] Step 3: independently adjust the height of the lifting mechanisms on both sides and adjust the angle between the axis of the winding shaft and the special-shaped winding mold and the weaving plane so that the fabric generatrix and the special-shaped winding mold always maintain a contoured tangent relationship.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] like Figure 1 , Figure 2 As shown, the lifting mechanism 1 can achieve lifting within a certain range by controlling the handle 101. The lifting mechanisms 1 on both sides are connected to the universal steering mechanism 4. The universal steering mechanism 4 can achieve telescopic extension within a certain distance to meet the different length requirements of the universal steering mechanism 4 when the special-shaped winding mold 5 changes at different angles. The universal steering mechanism 4 cooperates with the lifting mechanisms 1 on both sides to achieve different height combinations to achieve the angle tilt of the special-shaped winding mold 5 within a certain range to achieve the best winding position. The universal steering mechanism 4 is connected to the driving mechanism 2, and the driving mechanism 2 is activated to achieve the rotation of the entire winding device within a certain precision range.

[0035] like Figure 2 As shown, the lifting mechanism 1 is composed of a control handle 101, a locking mechanism 102, a slideway 103, and a moving slider 104. The control handle 101 and the moving slider 104 are rigidly connected, and the moving slider 104 is directly connected to the universal steering mechanism 4. By adjusting the movement of the control handle 101, the moving slider 104 is driven to move vertically in the slideway 103, and the slideways 103 on both sides can be adjusted asynchronously.

[0036] like Figure 3As shown, the universal steering mechanism 4 is composed of a left universal joint 401, an extension mechanism 402, a locking mechanism 403, and a right universal joint 404. The left universal joint 401 is connected to the left lifting mechanism 1, and the left universal joint 401 can realize multi-degree-of-freedom rotation in space. The tail of the left universal joint 401 is an extension mechanism 402, which can realize extension within a certain range. The extension of a specified distance can be locked by a mechanical mechanism, and the extension within a certain range can be performed according to the inclination angle of the special-shaped winding mold 5. The special-shaped winding mold 5 can be adjusted according to the distribution range of the warp yarn, adjusted to the optimal position, and locked by the locking mechanism 403. The locking mechanism 403 can be rigidly connected to the special-shaped winding mold 5 through a mechanical structure to ensure that the special-shaped winding mold 5 and the universal steering mechanism 4 rotate synchronously. The right universal joint 404 is connected to the right lifting mechanism 1.

[0037] Specifically, in this embodiment, the mechanical transmission part of the driving mechanism 2 includes a motor, a reducer, and a coupling. The motor is driven, and the motor and the reducer are fixed to the bottom of the frame by bolts, and are connected to the transmission shaft of the universal steering mechanism 4 through a plum blossom coupling, and the transmission shaft is fixed to the moving slider 104 by cooperating with a bearing.

[0038] like Figure 4 As shown in the figure, taking the weaving of conical cloth for conical fabric as an example, carbon fiber is used to weave conical cloth for conical fabric. Design and construct the conical mold, install the mold on the winding shaft, adjust the lifting mechanism on both sides to make the generatrix of the conical winding mold with different tapers parallel to the cloth fell, and fix the warp head on the conical mold. After the loom is used to open the warp, insert the weft and beat the weft, the driving mechanism drives the winding shaft to rotate a certain angle to realize the contour winding of the formed fabric. Since the warp is tangent to the parallel generatrix of the winding mold, there is no warp slip. After the fabric wound by the winding shaft wraps the conical winding mold for one week, the winding step is automatically adjusted through the control program to achieve stable control of the weft density.

[0039] The working process and principle of the present invention are as follows: Some special-shaped components that require high-performance fiber composite materials have surfaces that are mostly spatially undevelopable curved surfaces, so they cannot be spliced ​​into spatial curved surfaces through a combination of flat panel fabrics. The device of the present application mainly realizes the two functions of profiling and winding during the weaving process of special-shaped fabrics. During the fabric forming process, as the thickness of the fabric winding continues to increase, the generatrix at which the special-shaped winding mold and the fabric are tangent is also constantly changing. In order to ensure the uniformity of the warp and weft density of the fabric during the weaving process, the present device allows the angle at which the special-shaped winding mold and the fabric are tangent to change as the thickness of the fabric winding changes. The angle a of the present device will be adjusted and changed during the weaving process (such as Figure 5As shown in the figure, the device will also adjust the position of the special-shaped winding mold as the fabric thickness increases, ensuring that the fabric main line and the mold are tangent to each other, reducing the slippage of the warp yarn when the mold is wound, thereby controlling the uniformity of the warp and weft density of the fabric.

[0040] like Figure 6 As shown in FIG. 1 , according to the analysis of the changing law of the fabric generatrix during the forming process of the special-shaped fabric, during the forming process of the fabric, as the fabric is rolled up, the thickness of the mold increases continuously, and the generatrix position of the mold changes regularly. The control system controls the actions of the lifting drive devices of the lifting mechanisms 1 on both sides, so that the lifting mechanisms 1 on both sides are lifted and lowered according to the control programming law, thereby realizing the regular change of the inclination angle of the special-shaped winding mold 5, and controlling the profiling tangency of the generatrix of the special-shaped winding mold 5 and the plane fabric (such as Figure 7 As shown in FIG. 1 , the position of the special-shaped winding mold 5 is adjusted while the driving mechanism 2 drives the special-shaped winding mold 5 to wind the fabric through the universal steering mechanism 4 .

[0041] like Figure 8 As shown, a method for winding a special-shaped woven fabric with adjustable angle comprises the following steps:

[0042] Step 1: Adjust the position of the special-shaped winding mold on the winding shaft to ensure that the winding center is aligned with the weaving center;

[0043] Step 2, the driving mechanism drives the connecting shaft to rotate, thereby driving the special-shaped winding mold on the winding shaft to rotate, so as to realize the contoured winding of the special-shaped woven fabric;

[0044] Step 3: By independently adjusting the height of the lifting mechanisms on both sides, the angle between the axis of the winding shaft and the special-shaped winding mold and the weaving plane is adjusted so that the contours of the fabric generatrix and the special-shaped winding mold are always kept tangent.
