Description

Technical Field

[0001] The embodiments of this utility model relate to the field of weaving equipment technology, specifically to an integrated loom for weaving tow-stretching fabrics. Background Technology

[0002] As a key piece of equipment for realizing the weaving process, braiding machines have evolved over a long period into various types and specifications to meet the needs of different materials, weaving structures, and application scenarios. Carbon fiber fabrics possess excellent mechanical properties, such as high strength, high modulus, and low density. In the aerospace field, carbon fiber fabrics are widely used in the manufacture of key components such as aircraft fuselages and wings, effectively reducing aircraft weight and improving flight performance. In the automotive manufacturing field, they are used to manufacture car bodies and parts, enhancing vehicle safety and fuel economy.

[0003] Before carbon fiber precursors are woven into fabrics, they sometimes need to be broadened to improve their mechanical properties, making the fiber bundle thinner and wider. Furthermore, during the weaving process, to ensure a tight bond between the warp and weft yarns, a weft-beating operation is required. This involves applying a push force to each weft yarn in the direction of the woven fabric after each weft yarn is interlaced with the warp yarn, thereby enhancing the tightness of the bond between the warp and weft yarns and improving fabric quality.

[0004] When weaving stretched carbon fibers, the traditional weft-driving method is not suitable because the stretched carbon fiber fabric is relatively thin. For example, the weft-driving may not be in place because the contact between the weft-driving component and the weft yarn is not sufficient, or the weft-driving component and the weft yarn are prone to relative slippage when in contact, which makes it impossible for the weft yarn to be tightly woven with the warp yarn, resulting in inconsistent weaving density of the fabric, which in turn reduces the quality and performance of the fabric.

[0005] Therefore, there is an urgent need to develop a weaving equipment suitable for stretching carbon fiber fabrics to meet the manufacturing industry's demand for carbon fiber fabrics. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this utility model provide an integrated loom for weaving of tow-stretched fabrics, which solves the technical problem that traditional weft-beating methods in related technologies cannot meet the weft-beating effect requirements of carbon fiber fabrics.

[0007] According to one aspect, at least one embodiment of the present invention provides an integrated loom for weaving tow-widening fabrics, including a frame and a weaving mechanism, wherein the weaving mechanism includes a heddle assembly and a beat-up assembly; The heddle assembly consists of multiple sets and is slidably mounted on the frame. It is used to guide multiple sets of warp yarns. The multiple sets of heddle assemblies can drive the multiple sets of warp yarns to rise or fall respectively, so that the multiple sets of warp yarns form a weft opening between them for the weft yarn to pass through. The multiple sets of heddle assemblies can also drive the multiple sets of warp yarns to rise and fall alternately, so that a new weft opening is formed after a weft yarn passes through the weft opening, and finally a fabric woven by interlacing warp and weft yarns is formed. The weft insertion assembly includes a reed frame and reed blades. The reed frame is oscillatingly mounted on the machine frame. The reed blades are vertically positioned within the reed frame. There are multiple reed blades, spaced laterally. The lateral spacing between the multiple reed blades allows multiple warp yarns to pass through. Each reed blade has a weft insertion groove. After the weft yarn passes through the weft inlet, the weft insertion groove can push the weft yarn towards the woven fabric under the action of the reed frame, so that the weft yarn is tightly attached to the woven fabric.

[0008] For example, in at least one embodiment of this utility model, a tow-expanding fabric weaving integrated loom further includes: Both sides of the reed frame are provided with pressure-bearing parts and pressure blocks. The pressure blocks are slidably disposed on the side of the reed frame. The pressure blocks can press the end of the weft yarn to the pressure-bearing part after the weft yarn passes through the weft opening, so as to fix the weft yarn.

[0009] For example, in at least one embodiment of this utility model, a tow-expanding fabric weaving integrated loom further includes: The heald assembly includes a heald frame and a heald holder. The heald frame is slidably mounted on the frame and is vertically mounted inside the heald frame. There are multiple heald holders, which are spaced apart horizontally. The heald holders are provided with heald openings for guiding the warp yarns through.

[0010] For example, in at least one embodiment of this utility model, a tow-expanding fabric weaving integrated loom further includes: The heddle opening is provided with a pair of rotating guide rollers, with the space between the two guide rollers used for the warp yarn to pass through.

[0011] For example, in at least one embodiment of this utility model, a tow-expanding fabric weaving integrated loom further includes: It also includes a weft insertion assembly, which includes a weft yarn disc and a cutting unit located on one side of the heddle assembly, and a yarn clamping unit located on the other side of the heddle assembly. The weft yarn disc is rotatably mounted on the frame for mounting the weft yarn roll. The yarn clamping unit is slidably mounted on the frame and can pass through the weft opening and reset after clamping the end of the weft yarn, so that the weft yarn passes through the weft opening. The cutting unit is mounted on the frame for cutting the section of weft yarn that passes through the weft opening.

[0012] For example, in at least one embodiment of this utility model, a tow-expanding fabric weaving integrated loom further includes: The yarn clamping unit includes a sliding frame and clamping plates. The sliding frame is slidably mounted on the machine frame, and there are two clamping plates that are slidably mounted on the sliding frame. The two clamping plates are used to clamp the ends of the weft yarn.

[0013] For example, in at least one embodiment of this utility model, a tow-expanding fabric weaving integrated loom further includes: The cutting unit includes a base and a cutter. The base is mounted on the frame, and the cutter is slidably mounted on the frame. The base and the cutter are used to pass through the weft yarn. After the cutter descends, it can contact the base and cut the weft yarn.

[0014] For example, in at least one embodiment of this utility model, a tow-expanding fabric weaving integrated loom further includes: A yarn feeding unit is provided between the weft yarn roller and the cutting unit. The yarn feeding unit includes a support plate and a pressure plate. The support plate is slidably mounted on the frame, and the pressure plate is slidably mounted on the support plate. After the weft yarn is cut by the cutting unit, the pressure plate can press the end of the weft yarn to the support plate. The support plate can pull the end of the weft yarn in the direction of the cutting unit so that it can be clamped by the yarn clamping unit.

[0015] For example, in at least one embodiment of this utility model, a tow-expanding fabric weaving integrated loom further includes: It also includes a yarn feeding frame and a warp positioning frame. The yarn feeding frame is rotatably equipped with multiple warp bobbins for mounting warp yarn rolls. The warp positioning frame is equipped with multiple yarn separating rings, which are used to allow multiple warp yarns output from the yarn feeding frame to pass through, so as to comb the multiple warp yarns.

[0016] For example, in at least one embodiment of this utility model, a tow-expanding fabric weaving integrated loom further includes: A warp conveyor is provided between the warp positioning frame and the weaving mechanism. A yarn feeding roller and multiple expansion rollers are rotatably mounted on the warp conveyor. The warp yarns are conveyed alternately among the multiple expansion rollers. The multiple expansion rollers can expand the width of the warp yarns by means of the tension generated during conveying. The yarn feeding roller can rotate actively to convey the expanded warp yarns to the weaving mechanism.

[0017] The beneficial effects of the embodiments of this utility model are as follows: In this invention, multiple broadened carbon fiber warp yarns are divided into two groups, each passing through one of two heddle assemblies, and then correspondingly passing through the transverse gaps between multiple reeds, so that each warp yarn corresponds to one transverse gap. A conventional lifting drive device can be configured for the two heddle assemblies. During weaving, the two heddle assemblies are driven to rise and fall alternately. When one heddle assembly rises and the other falls, a weave opening is formed between the two warp yarns. At this time, under the action of an external traction component, the pre-broadened weft yarn is introduced and passes through this weave opening.

[0018] After the weft yarn passes through the weft hole, the reed frame, driven by a conventional oscillating drive device mounted on the frame, oscillates towards the already woven fabric, thereby causing multiple reed blades to oscillate synchronously. During the oscillation, the weft yarn passing through the weft hole enters the corresponding weft-beating grooves on multiple reed blades. The weft-beating grooves act as a limit, ensuring the weft yarn remains stably within the grooves, preventing relative slippage between the weft yarn and the reed blades, and guaranteeing good contact between the reed blades and the weft yarn. As the reed frame oscillates, the reed blades push the weft yarn towards the already woven fabric, causing the weft yarn to fit tightly against the woven fabric, completing the weft-beating operation. Afterwards, the two sets of heald assemblies operate again, exchanging their upper and lower positions, thereby weaving the weft yarn into the already woven fabric, while simultaneously forming a new weft hole for new weft yarns to pass through. This weaving and weft-beating process is repeated to achieve continuous weaving operations.

[0019] The weft insertion groove design on the reed in the weft insertion assembly avoids relative slippage between the weft yarn and the reed during the weft insertion process, ensuring good contact between the reed and the weft yarn. This allows the weft yarn to be tightly bonded to the woven fabric, thereby ensuring uniform weaving density and fabric quality. This helps carbon fiber fabrics fully utilize their high strength, high modulus, and other mechanical properties, meeting the stringent quality requirements of high-end manufacturing industries for carbon fiber fabrics.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] like Figures 1-10 The diagram illustrates an integrated weaving machine for tow-widening fabrics according to an embodiment of the present invention. It includes a frame 1 and a weaving mechanism 2, which comprises heddle yarn assemblies 201 and beat-up yarn assemblies 202. The frame 1 serves as the basic support structure for the entire loom. Multiple heddle yarn assemblies 201 are arranged in a lifting and sliding configuration on the frame 1. Each heddle yarn assembly 201 guides a different set of warp yarns, causing them to rise or fall, forming weft openings between the warp yarns. Furthermore, the heddle yarn assemblies 201 can alternately rise and fall, creating new weft openings after a weft yarn passes through, thus creating a cycle that ultimately forms a fabric woven from interlaced warp and weft yarns.

[0030] In the weft insertion assembly 202, the reed frame 2021 is oscillatingly mounted on the frame 1, and multiple reed blades 2022 are vertically arranged within the reed frame 2021, evenly distributed laterally. The reed blades 2022 are made of thin sheet-like metal. The lateral spacing between the multiple reed blades 2022 allows the spread carbon fiber warp yarns to pass through, ensuring the warp yarns are neatly aligned when passing through the reed blades 2022. Each reed blade 2022 has a weft insertion groove 20221, which allows the weft yarn to enter the weft insertion groove 20221 when the reed blade 2022 oscillates and pushes the weft yarn.

[0031] Working principle: Taking two sets of heddle assemblies 201 as an example, multiple broadened carbon fiber warp yarns are divided into two groups, passing through the two sets of heddle assemblies 201 respectively, and then passing through the transverse intervals between multiple reeds 2022 one by one, so that each warp yarn corresponds to one transverse interval. A conventional lifting drive device can be configured for the two sets of heddle assemblies 201. During the weaving process, the two sets of heddle assemblies 201 are driven to rise and fall alternately. When one set of heddle assemblies 201 rises and the other falls, a weave opening is formed between the two sets of warp yarns. At this time, under the action of the external traction component, the pre-broadened weft yarn is introduced and passes through this weave opening.

[0032] After the weft yarn passes through the weft hole, the reed frame 2021, driven by a conventional oscillating drive device mounted on the frame 1, oscillates towards the already woven fabric, thereby causing multiple reed blades 2022 to oscillate synchronously. During the oscillation, the weft yarn passing through the weft hole enters the corresponding weft-beating grooves 20221 on the multiple reed blades 2022. The weft-beating grooves 20221 act as a limiter, ensuring that the weft yarn is stably positioned within the grooves, preventing relative slippage between the weft yarn and the reed blades 2022, and ensuring good contact between the reed blades 2022 and the weft yarn. As the reed frame 2021 oscillates, the reed blades 2022 push the weft yarn towards the already woven fabric, causing the weft yarn to fit tightly against the already woven fabric, completing the weft-beating operation. Afterwards, the two sets of heddle assemblies 201 operate again, exchanging their upper and lower positions, thereby weaving the weft yarn into the already woven fabric, while simultaneously forming a new weft opening for the new weft yarn to pass through. This process of weaving and beating the weft is repeated to achieve continuous weaving operations.

[0033] The weft insertion groove 20221 design on the reed 2022 in the weft insertion assembly 202 avoids relative slippage between the weft yarn and the reed 2022 during the weft insertion process, ensuring good contact between the reed 2022 and the weft yarn. This allows the weft yarn to be tightly bonded to the woven fabric, thereby ensuring uniform weaving density and fabric quality. This helps carbon fiber fabrics fully utilize their high strength, high modulus, and other mechanical properties, meeting the stringent quality requirements of high-end manufacturing industries for carbon fiber fabrics.

[0034] In some examples, such as Figure 5 ,6 As shown, in the beat-up assembly 202, pressure-bearing parts 2023 and pressure blocks 2024 are provided on both sides of the reed frame 2021. The pressure-bearing parts 2023 are fixedly installed on the side of the reed frame 2021, and the pressure blocks 2024 are slidably disposed on the side of the reed frame 2021. During the weaving process, when the weft yarn passes through the weft hole, the pressure blocks 2024 slide towards the pressure-bearing parts 2023 under the action of an external power source (such as a cylinder, electric push rod, etc.), and the end of the weft yarn is firmly clamped, thereby maintaining stability during the beat-up process and preventing the weft yarn from shifting or shaking during the pushing of the reed plate 2022, thus ensuring the stability of the beat-up.

[0035] The heald assembly 201 consists of a heald frame 2011 and a heald holder 2012. The heald frame 2011 is slidably and vertically mounted on the frame 1, and its lifting movement is achieved by a lifting drive device on the frame 1. Multiple heald holders 2012 are vertically arranged within the heald frame 2011 and are evenly distributed horizontally. The heald holder 2012 has a heald opening 2013. Within the heald opening 2013, guide rollers 2014 are arranged in pairs and rotate. The gap between the two guide rollers 2014 is used to allow one warp yarn to pass through, thereby reducing the friction of the warp yarn during passage.

[0036] Working Principle: During the beat-up process, the weft yarn needs to remain stable to ensure it adheres tightly to the woven fabric. By setting pressure-bearing parts 2023 and pressure blocks 2024 on both sides of the reed frame 2021, the ends of the weft yarn are clamped and fixed after passing through the weft opening. This overcomes the displacement and swaying that may occur in the weft yarn under the beat-up force, ensuring the accuracy of the beat-up. During the weaving process, the warp yarn needs to move accurately along a preset path to form a neat weft opening for easy interweaving with the weft yarn. The heald frame 2012 and heald opening 2013 in the heald assembly 201 guide the warp yarn. Multiple heald frames 2012 are spaced laterally. The warp yarn passes through the heald opening 2013 on the heald frame 2012. Pairs of guide rollers 2014 inside the heald opening 2013 guide and support the warp yarn. The rotational design of the guide rollers 2014 reduces friction.

[0037] In some examples, such as Figure 9 , 10 As shown, a weft yarn disc 2031 and a cutting unit 2032 are provided on one side of the heddle assembly 201, and a yarn clamping unit 2033 is provided on the other side. The weft yarn disc 2031 is rotatably mounted on the frame 1 and is used to install the weft yarn roll. When the weft yarn is released, the weft yarn disc 2031 can be passively rotated.

[0038] In the cutting unit 2032, the base 20321 is mounted on the frame 1, and the cutter 20322 is slidably mounted on the frame 1, located above the base 20321. The cutter 20322 is connected to a conventional drive device (such as a cylinder or electric push rod). After the cutter 20322 descends and contacts the base 20321, it can cut the weft yarn between the two.

[0039] In the yarn clamping unit 2033, the sliding frame 20331 is slidably mounted on the frame 1 and can reciprocate in a direction parallel to the weft inlet. Two clamping plates 20332 are slidably mounted on the sliding frame 20331. The clamping plates 20332 are connected to a conventional drive device (such as a small cylinder or electric push rod) to realize the clamping and releasing operations of the weft yarn.

[0040] In the yarn feeding unit 2034, the support plate 20341 is slidably mounted on the frame 1 and can move linearly along the weft yarn feeding direction. The support plate 20341 is connected to a conventional drive device (such as an electric push rod) to control the sliding of the support plate 20341. The pressure plate 20342 is slidably mounted on the support plate 20341 and is connected to a conventional drive device (such as a small cylinder or electric push rod). When the cutting unit 2032 cuts the weft yarn, the pressure plate 20342 can descend and press the end of the weft yarn roll output onto the support plate 20341.

[0041] Working principle: After the heald assembly 201 drives the warp yarns to form a weave opening, the sliding frame 20331 of the yarn clamping unit 2033 passes through the weave opening, and the two clamping plates 20332 open. When the sliding frame 20331 reaches the weft yarn position, the clamping plates 20332 close and clamp the end of the weft yarn. Subsequently, the sliding frame 20331 slides in the opposite direction and returns to its initial position, thereby pulling the weft yarn through the weave opening. During the process of the weft yarn being pulled through, the weft yarn disc 2031 is passively rotated due to the pull of the weft yarn, releasing the weft yarn.

[0042] After the weft yarn is pulled past the weft opening by the clamping unit 2033, the cutter 20322 descends and cuts the weft yarn. The cut end of the weft yarn will be clamped by the pressure block 2024 and the pressure bearing part 2023 on the reed frame 2021 so that subsequent weft insertion operations can be carried out.

[0043] While the cutting unit 2032 cuts the weft yarn, the pressure plate 20342 descends and presses the end of the weft yarn roll against the support plate 20341 to prevent the weft yarn end from loosening. The support plate 20341 supports the end of the weft yarn roll, preventing it from sagging due to its own weight. Then, the support plate 20341 slides towards the cutting unit 2032, moving forward with the end of the weft yarn roll, and delivering the weft yarn end to the clamping position, waiting for the next clamping unit 2033 to clamp it, preparing for the next weft insertion operation.

[0044] In some examples, such as Figure 1 ,2 As shown, the yarn release frame 3 serves as a release device for the warp yarn rolls. Multiple warp yarn tubes 301 are rotatably mounted on the yarn release frame 3 for mounting the warp yarn rolls. The warp yarn positioning frame 4 is located behind the yarn release frame 3 and is equipped with multiple yarn separating rings 401. After the warp yarns are released from the warp yarn tubes 301, they pass through the corresponding yarn separating rings 401, allowing the warp yarns to be combed and arranged neatly, preventing them from tangling and preparing them for subsequent weaving processes.

[0045] The warp conveyor frame 5 is positioned between the warp positioning frame 4 and the weaving mechanism 2. The yarn feed roller 501 is rotatably mounted on the warp conveyor frame 5, located at its end and close to the weaving mechanism 2. Driven by a motor, the yarn feed roller 501 actively rotates, conveying the warp yarns to the weaving mechanism 2. Multiple extension rollers 502 are rotatably mounted on the warp conveyor frame 5. The warp yarns are interleaved among the extension rollers 502. As the warp yarns interleave among the extension rollers 502, they expand in width under tension, achieving the required width for weaving.

[0046] Working principle: After the warp yarns are released from the warp bobbin 301 on the yarn release frame 3, they pass through the yarn separating rings 401 on the warp positioning frame 4, with each warp yarn passing through its corresponding separating ring 401. The separating rings 401 guide and comb the warp yarns, ensuring that multiple warp yarns are arranged in an orderly manner and preventing them from tangling. After being combed by the warp positioning frame 4, the warp yarns enter the warp conveyor frame 5. On the warp conveyor frame 5, the warp yarns are conveyed alternately between multiple spreading rollers 502. Under tension, the width of the warp yarns gradually expands, achieving a widening effect. The feeding roller 501 is located at the end of the warp conveyor frame 5, conveying the widened warp yarns to the weaving mechanism 2.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
