Description

Technical Field

[0001] The invention belongs to the technical field of weaving equipment, in particular to a carbon fiber three-dimensional fabric weaving machine. Background Art

[0002] With the growing demand for high-performance materials in modern industry, carbon fiber three-dimensional fabrics have been widely used in many fields such as aerospace, automobile manufacturing, and high-end sports equipment due to their excellent strength-to-weight ratio, high temperature resistance, and chemical corrosion resistance. The weaving quality of carbon fiber three-dimensional fabrics directly affects the performance of the final product, and the weaving machine, as the key equipment to realize this weaving process, plays a decisive role in its technical level.

[0003] At present, mainstream carbon fiber 3D fabric weaving machines generally include a fixed-position rotating ring frame and a fixed rotating ring component. The rotating rotating ring component drives the weaving rotation to achieve a complex weaving process. However, in the weaving process, that is, the routing of the carbon fiber 3D fabric line, the carbon fiber 3D fabric line is usually routed directly on the wiring board with a narrow slit. The narrow slit on the wiring board is intended to plan the initial path for the fabric line so that it can enter the subsequent weaving process in an orderly manner.

[0004] However, the carbon fiber 3D fabric line itself is relatively rigid and not easy to bend and deform. At the same time, it has poor flexibility and is difficult to flexibly adjust its position in a small space. Based on these characteristics, when a large number of carbon fiber 3D fabric lines are crowded in the narrow routing gap of the distribution board, relying solely on the physical constraint of the narrow gap is far from enough. It is still very easy for two adjacent carbon fiber 3D fabric lines to be interlaced, thereby disrupting the weaving rhythm. Not only will the weaving pattern be very different from the preset structure, but it will also affect the final performance of the fabric and fail to meet the expected standards, reducing the quality and reliability of the product.

[0005] Therefore, a carbon fiber three-dimensional fabric weaving machine is proposed to solve the above problems. Summary of the invention

[0006] In order to solve the problems raised in the above background technology, the present invention provides a carbon fiber three-dimensional fabric weaving machine.

[0007] To achieve the above object, the present invention provides the following technical solution: a carbon fiber three-dimensional fabric weaving machine, comprising: A comb member is arranged on the trajectory of the carbon fiber yarn and is used to comb the carbon fiber yarn; Among them, the trajectory of the carbon fiber yarn includes a straight trajectory and a circumferential rotation trajectory; The dynamic ring rotates along with the circumferential rotation trajectory of the carbon fiber yarn; The comb member comprises: A comb head is arranged on the moving ring and contacts with the carbon fiber yarn, and combs the carbon fiber yarn along a straight line trajectory of the carbon fiber yarn; A positioning member connected to the comb head is used to determine the position of the comb head on the circumferential line of the moving ring and adapt to the straight trajectory of the carbon fiber yarn; The comb heads and positioning members are distributed on the moving ring in an array.

[0008] In the above technical solution, preferably, it also includes: The card slots are distributed in a circular array inside the dynamic ring; The positioning member comprises: A card block abuts against the card slot; The pushing member is connected to the card block and is used to push the card block to move toward / away from the card slot to engage / release the engagement.

[0009] In the above technical solution, preferably, it also includes: A slider connected to the comb head and circumferentially sliding around the axis of the moving ring in the moving ring; The pusher comprises: An inclined block is slidably disposed in the sliding block; The clamping block is provided with an inclined groove adapted to the inclined surface end of the inclined block; The two ends of the spring are respectively connected with the clamping block and the moving ring.

[0010] In the above technical solution, preferably, it also includes: The static elimination ring is located outside the dynamic ring, and the ion wind is ejected to contact the carbon fiber yarn: The ions carried by the ion wind neutralize the static charge on the surface of the carbon fiber yarn in equal amounts, eliminating static electricity.

[0011] In the above technical solution, preferably, the static elimination ring includes: A first annular ion air knife and a second annular ion air knife are respectively arranged on both sides of the comb member; The ion wind trajectories ejected by the first annular ion wind knife and the second annular ion wind knife are arranged opposite to each other in a direction toward the combing bar member combing the carbon fiber yarns.

[0012] In the above technical solution, preferably, the dynamic ring includes a first mounting ring, a second mounting ring and a third mounting ring for respectively assembling the first annular ion air knife, the comb member and the second annular ion air knife; A cover is provided between the outer sides of the first mounting ring and the third mounting ring. The cover, the first mounting ring and the third mounting ring are combined to form a static elimination area. The second mounting ring is located in the static elimination area.

[0013] In the above technical solution, preferably, it also includes a stationary ring, the moving ring is rotatably arranged outside the stationary ring, a fixing rod is arranged on the stationary ring, and the other end of the fixing rod is fixedly connected to the rotating ring frame of the braiding machine.

[0014] In the above technical solution, preferably, a dust guide cavity connected to the static elimination area is provided inside the static ring, and a dust guide pipeline connected to the dust guide cavity is provided outside the static ring.

[0015] In the above technical solution, preferably, an antistatic rubber cover is provided between adjacent positioning members to cover the moving track of the positioning members on the circumferential line of the dynamic ring.

[0016] In the above technical solution, preferably, a follower rod is provided on the movable ring, and the other end of the follower rod is connected to the rotating ring component of the braiding machine. The rotating ring component drives the carbon fiber yarn to rotate circumferentially, and the follower rod drives the movable ring to move along the circumferential rotation trajectory of the carbon fiber yarn.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention adapts to the straight trajectory of the carbon fiber yarn through the positioning member and the comb head, that is: no matter how the yarn position changes, it can accurately adapt to the yarn to perform the combing operation. Specifically, the comb member goes deep into the fabric lines to gradually separate the mutually entangled and intertwined lines, and comb the messy carbon fiber yarn smoothly, which plays the role of untangling and straightening, ensuring that the subsequent weaving process can be carried out based on the neat and orderly yarn, thereby ensuring the precision of the fabric structure and the stability of the mechanical properties.

[0018] Furthermore, through the coordinated operation of the pushing member and the clamping block, the position adjustment process of the comb head is accurate and fast. The inclined block is used as the operating end to be parallel to the axis of the moving ring and perpendicular to the rotation direction. The centrifugal force generated by the rotation of the moving ring can also avoid interference with the position of the comb head. It is ensured that the comb head is still accurately in the position adapted to the straight trajectory of the carbon fiber yarn when the moving ring rotates, and will not be offset or misplaced due to centrifugal force, thereby ensuring the accuracy and stability of the yarn combing.

[0019] The present invention also uses a static elimination ring to spray ion wind to directly contact the carbon fiber yarn, and uses the principle of equal neutralization of ions and static charges on the yarn surface to effectively prevent the yarns from being entangled and sticking to each other due to static electricity; Furthermore, through the relative ion wind trajectories of the first annular ion air knife and the second annular ion air knife, combined with the cover between the outer sides of the first mounting ring and the third mounting ring and the enclosure of the two, a static elimination area is formed, thereby forming a strong static electricity protection for the yarn combing area and reducing external interference. The double protection improves the static electricity elimination effect and creates a stable static electricity environment for yarn combing and weaving.

[0020] By setting up the dust guide cavity inside the static ring and the external dust guide pipeline, dust and other impurities generated by the elimination of static electricity by ion wind can be cleaned in time, keeping the inside of the equipment clean and avoiding the influence of impurities on the yarn combing quality and equipment operation.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1 , Figure 5 As shown, the present invention provides a carbon fiber three-dimensional fabric weaving machine, comprising: A comb member 1 is arranged on the trajectory of the carbon fiber yarn and is used to comb the carbon fiber yarn; Among them, the trajectory of the carbon fiber yarn includes a straight trajectory and a circumferential rotation trajectory; The dynamic ring 2 rotates along with the circumferential rotation trajectory of the carbon fiber yarn; The comb member 1 comprises: The comb head 11 is arranged on the moving ring 2 and contacts with the carbon fiber yarn, and combs the carbon fiber yarn along the straight track of the carbon fiber yarn; The comb head 11 focuses on combing the yarn in the straight trajectory stage. At this time, the movement of the yarn is relatively regular and single. The comb head 11 can exert force accurately and efficiently untie the possible entanglement and disorder of the yarn, and deliver straight and neat yarn for the subsequent more complex rotary weaving links, ensuring the weaving accuracy and quality.

[0025] The positioning member 12 is connected to the comb head 11 and is used to determine the position of the comb head 11 on the circumferential line of the moving ring 2 to adapt to the straight trajectory of the carbon fiber yarn; The function of the positioning member 12 is to accurately lock the position of the comb head 11 on the circumferential ring line of the moving ring 2 according to the change of the linear trajectory of the carbon fiber yarn, that is: no matter how the linear direction of the yarn is adjusted due to the requirements of the weaving process, it can ensure that the comb head 11 is always at the best combing working point to prevent the adjacent yarns from interlacing, knotting and other undesirable situations caused by the deviation of the combing position, thereby ensuring the orderly arrangement of the yarn.

[0026] The comb heads 11 and the positioning members 12 are distributed on the moving ring 2 in an array.

[0027] In actual industrial production, it is usually necessary to process multiple strands of carbon fiber yarn at the same time. Combined with the array-type comb heads 11 and positioning members 12, each strand of yarn can be taken care of by its own comb head 11 and positioning member 12, thus avoiding omissions or loss of focus in the combing process, and greatly improving the overall combing efficiency.

[0028] like Figures 7 and 8 As shown, it also includes: The card slots 13 are distributed in the moving ring 2 in a ring array; The positioning member 12 comprises: The card block 121 abuts against the card slot 13; The pushing member 122 is connected to the clamping block 121 and is used to push the clamping block 121 to move toward or away from the clamping slot 13 to engage or disengage.

[0029] like Fig. 9 As shown, it also includes: The slider 123 is connected to the comb head 11 and slides circumferentially around the axis of the moving ring 2 in the moving ring 2; The pusher 122 includes: The inclined block 1221 is slidably disposed in the sliding block 123; The block 121 is provided with an inclined groove 1222 adapted to the inclined surface end of the inclined block 1221; The two ends of the spring 1223 are respectively connected to the clamping block 121 and the moving ring 2.

[0030] Specifically, the inclined block 1221 includes an L-shaped block and an inclined plate, the inclined plate is arranged at the horizontal end of the L-shaped block, and the inclined plate is slidably arranged in the inclined groove 1222; The operator can push the card block 121 to move closer to or away from the card slot 13 through the inclined block 1221 as needed, and easily achieve engagement or disengagement. This design provides great convenience for responding to different weaving process requirements, yarn specification changes or equipment maintenance. For example, when it is necessary to adapt to carbon fiber yarns in different positions, the comb head 11 can be quickly adjusted to ensure adaptive combing of the yarn.

[0031] During the operation of the braiding machine, the moving ring 2 rotates circumferentially with the yarn to generate centrifugal force. The inclined surface of the inclined block 1221 interacts with the inclined groove 1222 in the clamping block 121 to decompose and transform the centrifugal force to avoid being affected. At the same time, the spring 1223 plays an elastic buffering and resetting role to maintain the stable clamping state of the clamping block 121, so that the yarn combing is not disturbed by the centrifugal force.

[0032] like Figure 1 to Figure 2 As shown, it also includes: The static elimination ring 3 is arranged outside the moving ring 2, and the ion wind is ejected to contact the carbon fiber yarn: The ions carried by the ion wind neutralize the static charge on the surface of the carbon fiber yarn in equal amounts, eliminating static electricity.

[0033] By using the principle of equal neutralization of ions and static charges on the yarn surface, the hidden danger of static electricity is eliminated from the root. This is crucial for carbon fiber, a material that is very prone to static adsorption. It effectively prevents the yarns from getting entangled and sticking to each other due to static electricity, ensures the smoothness of the yarns during the entire process of combing and weaving, and lays the foundation for the subsequent weaving of high-quality carbon fiber three-dimensional fabrics.

[0034] like Figure 3 to Figure 4 As shown, the static elimination ring 3 includes: A first annular ion air knife 31 and a second annular ion air knife 32 are respectively arranged on both sides of the comb member 1; The ion wind trajectories ejected by the first annular ion wind knife 31 and the second annular ion wind knife 32 are arranged opposite to each other in a direction toward the combing bar member 1 combing the carbon fiber yarns.

[0035] During the combing stage when the yarn needs to be straightened the most, the double ion wind coverage ensures further improvement of the static electricity elimination effect and greatly reduces the yarn disorder problem caused by static electricity.

[0036] Among them, the electrical connection between the first annular ion air knife 31 and the second annular ion air knife 32 can be electrically connected through an electric slip ring, that is, the electric slip ring can be arranged on the rotating ring frame or the fixed rod 7, and the two end wires are respectively connected to the ion air knife and the external control system. This design solves the problem of entanglement of the ion air knife line during the rotation of the moving ring 2, ensuring that the ion air knife can stably follow the rotation of the moving ring 2, and continuously provide uninterrupted static electricity elimination service for the yarn, and the static electricity elimination function will not be interrupted due to line problems.

[0037] like Figure 3 , Figure 4 , Figure 6 As shown, the dynamic ring 2 includes a first mounting ring 21, a second mounting ring 22 and a third mounting ring 23 for assembling the first annular ion air knife 31, the comb member 1 and the second annular ion air knife 32 respectively; If the static elimination device fails, maintenance personnel can quickly locate the static area and easily access related components for maintenance by removing the cover 24, without having to disassemble the overall structure of the knitting machine on a large scale, thereby improving the availability of the equipment.

[0038] A cover 24 is provided between the outer sides of the first mounting ring 21 and the third mounting ring 23. The cover 24, the first mounting ring 21 and the third mounting ring 23 enclose a static elimination area 25. The second mounting ring 22 is located in the static elimination area 25. A relatively closed and focused static electricity elimination space, in which the ion winds ejected by the first annular ion wind knife 31 and the second annular ion wind knife 32 can act on the carbon fiber yarn more efficiently, maximize the static electricity neutralization effect, and greatly reduce the problems of yarn entanglement and interlacing caused by static electricity adsorption.

[0039] Specifically, the second mounting ring 22 is fixed between the first mounting ring 21 and the third mounting ring 23 by a connecting rod, so as to maximize the space of the static elimination area 25, avoid interference between devices, and reduce the risk of additional static electricity generated due to friction between components.

[0040] like Figures 2 to 3 As shown, it also includes a stationary ring 6, and the dynamic ring 2 is rotatably arranged outside the stationary ring 6. A fixing rod 7 is arranged on the stationary ring 6, and the other end of the fixing rod 7 is fixedly connected to the rotating ring frame of the braiding machine.

[0041] The rotating ring frame serves as the basic supporting structure for the rotational movement of the entire carbon fiber yarn (this is the prior art, so no further description is given). The stationary ring 6 is stably fixed in a suitable position through the fixing rod 7, ensuring that the moving ring 2 and the comb member 1, ion air knife and other key components thereon can operate smoothly without shaking or deflection due to lack of stable support, which affects the yarn combing and weaving accuracy.

[0042] like Figure 3, Figure 4 ,to Figure 6 As shown, a dust guiding cavity 8 communicating with the static elimination area 25 is provided inside the static ring 6 , and a dust guiding pipeline 9 communicating with the dust guiding cavity 25 is provided outside the static ring 6 .

[0043] During the static elimination process, when the ion wind sprayed by the ion wind knife acts on the carbon fiber yarn, the dust and impurities on the yarn will be blown up. If these dusts accumulate in the static elimination area 25, it will not only affect the propagation path and effect of the ion wind, but also may generate static electricity again due to friction. The existence of the dust guide cavity 25 and the dust guide pipeline 9 can discharge these dusts in time, keep the static elimination area 25 clean, continuously optimize the static neutralization efficiency of the ion wind, and ensure that the yarn is always in a good static environment. Among them, the other end of the dust guide pipeline 9 is connected to an external processing device (this is the existing technology, so no further description is made), such as an electrostatic precipitator.

[0044] like Figure 5 As shown, an antistatic rubber cover 4 is provided between adjacent positioning members 12 to cover the moving track of the positioning members 12 on the circumferential loop of the dynamic ring 2 .

[0045] During the operation of the knitting machine, foreign objects such as dust and impurities may enter the moving track area of ​​the positioning member 12. Once these foreign objects accumulate, they may interfere with the normal movement of the positioning member 12, affect the engagement and disengagement operation of the clamping block 121 and the clamping slot 13, and further cause deviation in the position adjustment of the comb head 11, thereby reducing the accuracy of combing. The antistatic rubber cover 4 can effectively cover the moving track of the positioning member 12, forming a physical barrier to prevent dust and impurities from entering.

[0046] The antistatic rubber cover 4 has antistatic properties, which can reduce the accumulation of static electricity around the positioning member 12, avoid static electricity interfering with the adjustment accuracy of the positioning member 12, and further ensure the accuracy of the position adjustment of the comb head 11.

[0047] like Figure 2 As shown, a follower rod 5 is provided on the movable ring 2, and the other end of the follower rod 5 is connected to the rotating ring component of the braiding machine. The rotating ring component drives the carbon fiber yarn to rotate circumferentially, and the follower rod 5 drives the movable ring 2 to move along the circumferential rotation trajectory of the carbon fiber yarn.

[0048] The follower rod 5 establishes a close connection between the moving ring 2 and the rotating ring component of the braiding machine. Since the rotating ring component drives the carbon fiber yarn to rotate in the circumferential direction (this is a prior art, so no further description is given), the follower rod 5 can transmit the movement of the rotating ring component to the moving ring 2 in real time, so that the comb member 1 on the moving ring 2 and the carbon fiber yarn always maintain a relatively stable position relationship during the entire rotation process, and the comb head 11 can continuously and accurately comb the yarn.

[0049] The working principle and use process of the present invention: According to the process requirements of the carbon fiber three-dimensional fabric to be woven, the initial position of the comb head 11 is adjusted. The operator can push the inclined block 1221 to move along the inclined surface of the inclined groove 1222 by operation, so that the clamping block 121 moves and is released from the clamping groove 13. The spring 1223 stores energy, and after the comb head 11 is moved to a suitable position, the inclined block 1221 is pushed and the spring 1223 is reset to drive the clamping block 121 to re-enter the clamping groove 13 to complete the positioning; The carbon fiber yarn enters the weaving process and is first combed by the comb head 11 to untangle and disorganize the yarn. At the same time, the first annular ion air knife 31 and the second annular ion air knife 32 spray ion wind. The ion wind sprayed by the ion air knife continuously neutralizes the static electricity on the surface of the yarn and performs static electricity elimination on the yarn. The dust guide chamber 8 and the dust guide pipeline 9 discharge the dust generated by the ion wind in real time to keep the static electricity elimination area 25 clean, thus completing the entire combing, static electricity elimination and dust guide operations.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
