[0033] Currently, three-dimensional tubular fabrics can be combined with thermosetting resins to create a tubular composite material. Compared to traditional metal materials, these tubular composite materials offer comparable heat resistance and rigidity, are lighter, and have a wider range of applications, such as in the automotive and military industries. To produce these tubular composite materials, a variety of weaving equipment and methods are currently available on the market. However, these weaving methods and equipment have low levels of automation and high levels of manual labor, resulting in uneven fabric structure, unstable tension control, and poor product quality consistency.

[0034] In order to solve the above problems, the present invention provides a three-dimensional cylindrical fabric loom. Figures 1 to 11 This is a specific embodiment of the three-dimensional cylindrical fabric loom provided by the present invention.

[0035] See also Figures 1 to 11 The three-dimensional cylindrical fabric loom 100 includes a main frame 1, a core mold cylinder 2, a weft beating mechanism 3, a harness lifting mechanism 7 and a weft insertion mechanism 8. The present application does not limit the specific structure of the main frame 1, which can be as follows: Figure 1The circular plate-shaped workbench shown in the figure, which is supported by a plurality of rods, can be a scaffolding-like frame or other structure formed by a plurality of rods, as long as it can be used to support other mechanisms. The core mold cylinder 2 is arranged on the main frame 1, and the core mold cylinder 2 extends along the up and down directions (the up and down directions in this application refer to the up and down directions in real life), and is arranged on the main frame 1. The core mold cylinder 2 is driven up and down by the first driving mechanism 4. The outer side of the core mold cylinder 2 is provided with a clamping ring 5, which is a circular ring arranged on the outer side of the core mold cylinder 2, and the clamping ring 5 is also fixed on the main frame 1; the beating mechanism 3, including a ring arranged around the outer side of the core mold cylinder 2 There are multiple reed blades 31, each of which is driven up and down by a second driving mechanism 6; a shedding mechanism 7 is arranged on the periphery of the beating-up mechanism 3; and a weft insertion mechanism 8 is driven to rotate around the core mold cylinder 2 by a third driving mechanism 9; wherein the warp yarn is divided into multiple parts corresponding to the multiple reed blades 31, one end of each warp yarn is connected to the shedding mechanism 7, and the other end passes through the corresponding reed blade 31 and is fixed to the top of the core mold cylinder 2, the shedding mechanism 7 drives the multiple warp yarns to open in sequence, and the weft insertion mechanism 8 is always in the opening of each warp yarn, driving the weft thread to pass through the corresponding opening. After the weft thread passes through the opening, the beating-up mechanism 3 cooperates to beat-up.

[0036] The technical solution of the present invention does not limit the specific structures of the first driving mechanism 4, the second driving mechanism 6, the third driving mechanism 9, the beating-up mechanism 3, the harness raising mechanism 7 and the weft insertion mechanism 8. The present invention mainly arranges these mechanisms reasonably so that the above-mentioned mechanisms cooperate with the core mold cylinder 2 to produce cylindrical fiber fabrics.

[0037] Specifically, the first driving mechanism 4, the second driving mechanism 6 and the third driving mechanism 9 can be a cylinder, a structure in which a screw rod cooperates with a screw rod, or other structures that can drive the corresponding mechanisms to move; the heddle lifting mechanism 7 generally includes a large number of heddle through-holes, each of which has a warp yarn passing through it, and each portion of the warp yarn passes through a plurality of heddle through-holes arranged in parallel, and the plurality of heddle through-holes corresponding to each portion of the warp yarn are driven by a driving member, which can be a cylinder, a telescopic motor or other driving structure, driving each portion of the warp yarn to be divided into two bundles of warp yarn, and the two bundles of the warp yarn are staggered on the outside of the core mold tube 2 to form an opening; the weft insertion mechanism 8 is also not specifically limited, and the weft insertion mechanism 8 is generally a sleeve rod that is sleeved on the outside of the weft thread, and a plurality of weft rings are provided around the sleeve rod, through which the weft threads are passed in sequence. The number of the plurality of weft rings is not limited, and can be 2, 3, 4, 6, etc. The more weft rings there are, the straighter and tighter the weft threads will be stretched. The optimal number of weft rings is 5-6. Too many will cause trouble for threading, and too few will cause the weft threads to be not stretched straight enough. The beating mechanism 3 includes a plurality of reed blades 31. The number of the plurality of reed blades 31 is not specifically limited, and can be 2, 3, 4, etc. Generally, in implementation, the optimal number of the reed blades 31 is 8, which can surround the core mold cylinder 2 as much as possible without causing too many warp yarns on each reed blade 31.

[0038] In the technical solution of the present invention, the three-dimensional cylindrical fabric loom 100 also includes a warp feeding mechanism 10, which is a mechanism for feeding the warp yarn to the shedding mechanism 7. Generally, the warp feeding mechanism 10 includes a bobbin 101 for separating the warp yarns, a tension unit 102 for straightening the warp yarns, and a yarn gathering unit 103 for gathering the warp yarns. The specific structure of the warp feeding mechanism 10 is not limited in this application. In addition to the above-mentioned components, it can also include other components for gathering and straightening the warp yarns. The warp feeding mechanism 10, the core mold cylinder 2, the weft beating mechanism 3, the shedding mechanism 7 and the weft insertion mechanism 8 together constitute the three-dimensional cylindrical fabric loom 100. The loom of the present invention cooperates the weft insertion mechanism 8, the shedding mechanism 7 and the weft beating mechanism 3 on the periphery of the core mold cylinder 2, so that the three-dimensional cylindrical fabric loom 100 can automatically weave cylindrical fiber fabrics to improve the degree of automation and produce fabrics with uniform structure and stable tension through the machine.

[0039] Furthermore, the core mold cylinder 2 includes: a limiting cylinder 21, the side wall of which is composed of a plurality of vertical first steel needles 21a arranged in a ring, the plurality of first steel needles 21a are evenly spaced, the top ends of the plurality of first steel needles 21a are fixed on a horizontally arranged annular upper support plate 21b, and the bottom ends are fixed on a horizontally arranged lower support plate 21c; and a cylindrical cylinder 22, which is arranged below the lower support plate 21c, and the top end of the cylindrical cylinder 22 is fixed to the lower support plate 21c; wherein the clamping ring 5 is sleeved on the outside of the cylindrical cylinder 22, and the beating mechanism 3 and the weft insertion mechanism 8 are arranged around the outside of the cylindrical cylinder 22. The specific structure of the core mold cylinder 2 is as follows: Figure 2 and Figure 3 As shown, the core mold cylinder 2 includes the limiting cylinder 21 located at the top and the columnar cylinder 22 located at the bottom. The present application does not limit the specific number of the plurality of first steel needles 21a. The purpose of the plurality of first steel needles 21a is to be used for clamping the warp yarns between the adjacent first steel needles 21a to play a certain limiting role. Therefore, the gap between the two adjacent first steel needles 21a should be as narrow as possible to play a certain resistance role on the warp yarns. The other end of the warp yarn is fixed in the limiting position through the gap between the two adjacent first steel needles 21a. The top of the cylinder 21, the present invention does not specifically limit the component for fixing the other end of the warp yarn. The other end of the warp yarn can be clamped between two pressing blocks, or can be directly pressed on the top of the limiting cylinder 21 by a pressing block; the clamping ring 5 is sleeved on the outside of the columnar cylinder 22, and the formed cylindrical fiber fabric will be driven by the first driving mechanism 4 to the top of the clamping ring 5. The formed cylindrical fiber fabric is tightened by the tightening action of the clamping ring 5 and the limiting cylinder 21 to avoid loosening during the weaving process of the fiber fabric.

[0040] Specifically, if Figure 11 As shown, the clamping ring 5 can be fixed to the main frame 1 by multiple rods, or fixed to the main frame 1 by other supports. The upper support plate 21b is arranged in an annular shape, which forms the top of the limiting cylinder 21 with an open shape. This is conducive to placing the component that can fix the other end of the warp yarn into the limiting cylinder 21. The specific shape of the lower support plate 21c is not limited. It can be a triangular, circular, or other plate structure for fixing multiple first steel needles 21a. Optimally, the lower support plate 21c is a circular plate, which is beautiful and easy to produce.

[0041] In the technical solution of the present invention, Figure 4As shown, a specific structure for fixing the warp yarn is given, including a plurality of first pressing blocks 21d and a plurality of second pressing blocks 22e. The number of the plurality of first pressing blocks 21d is the same as the number of the plurality of reed blades 31, because the warp yarn passes through the corresponding reed blade 31 and reaches the corresponding first pressing block 21d. The number of the plurality of reed blades 31 is 4, 5, 6..., and the number of the plurality of first pressing blocks 21d is equal to the number of the plurality of reed blades 31. Each of the first pressing blocks 21d is fixed on the top surface of the lower support plate 21c located in the limiting cylinder 21. The first pressing block 21d and the lower support plate 21c can be connected by screws, adhesives, etc., and the second pressing block 22e is stacked on the top of each first pressing block 21d. The second pressing block 22e and the first pressing block 21d can be detachably connected by bolts, magnetism, etc. When the other end of the warp yarn needs to be fixed, the other end of the warp yarn is laid on the top surface of the first pressing block 21d, and the second pressing block 22e is fixed on the top surface of the first pressing block 21d, thereby fixing the other end of the warp yarn, and the operation is convenient and quick.

[0042] Specifically, the side wall of the cylindrical tube 22 is also composed of a plurality of second steel needles 22a arranged in a ring. The number of the plurality of second steel needles 22a is not limited, and there is no clear requirement for the gap between two adjacent second steel needles 22a. Therefore, the number of the plurality of second steel needles 22a can be set according to production needs or aesthetics. The core mold tube upper cover plate 22b and the core mold tube lower cover plate 22c are used to fix the plurality of second steel needles 22a. This application does not limit the specific shapes of the core mold tube upper cover plate 22b and the core mold tube lower cover plate 22c. They can be triangular, rectangular and circular, preferably circular plates, for the sake of aesthetics and ease of production.

[0043] In the technical solution of the present invention, the first driving mechanism 4 includes a lower welding plate 41, a rotating motor 43, a screw 44 and a screw nut 45. The lower welding plate 41 is horizontally arranged in the cylindrical tube 22. At least one support rod 42 is vertically provided at the bottom of the lower welding plate 41. The top of each support rod 42 is fixedly connected to the bottom surface of the lower welding plate 41, and the bottom end passes through the lower cover plate 22c of the core mold cylinder and is fixedly connected to the main frame 1; the rotating motor 43 is vertically arranged on the main frame 1 and the middle of the core mold cylinder lower cover plate 22c, the rotating motor 43 is fixedly connected to the core mold cylinder lower cover plate 22c; a screw rod 44 is coaxially arranged in the cylindrical cylinder 22, the top end of the screw rod 44 is connected to the bottom surface of the lower welding plate 41, and the bottom end passes through the core mold cylinder lower cover plate 22c and is connected to the rotating motor 43; and a screw rod nut 45 is sleeved on the outside of the screw rod 44, and the bottom of the screw rod nut 45 is connected to the top surface of the core mold cylinder lower cover plate 22c.

[0044] like Figure 3 As shown, the lower welding plate 41 is fixed to the top of the main frame 1 by at least one support rod 42, and the at least one support rod 42 can be 1, 2, 3, etc. The lower welding plate 41 is arranged inside the cylindrical cylinder 22, and each of the support rods 42 is fixed to the main frame 1 through the lower cover plate 22c of the core mold cylinder, and the rotating motor 43 is fixed to the bottom of the lower cover plate 22c of the core mold cylinder and is connected to the screw rod 44. In order to enable the screw rod 44 to rotate when the rotating motor 43 is running, the top end of the screw rod 44 is rotatably connected to the lower welding plate 41, for example, by a bearing connection, or a rotating rod is provided at the bottom of the lower welding plate 41, and the free end of the rotating rod passes through the top of the screw rod 44 and is rotatably engaged with the top of the screw rod 44, etc. Other connection methods are used to achieve the rotational connection, such as Figure 3 As shown, the screw nut 45 is sleeved on the outside of the screw 44 and fixed to the lower cover plate 22c of the core mold cylinder. The fixing here can be welding, bonding or some other connection methods.

[0045] When the first driving mechanism 4 is in operation, the rotating motor 43 drives the screw rod 44 to rotate, and the rotation of the screw rod 44 drives the screw nut 45 to have a rotation tendency. Since at least one of the support rods 42 limits the rotation of the screw rod nut 45, the screw rod nut 45 moves up and down on the screw rod 44, thereby driving the core mold tube 2 to move up and down. The use of this first driving mechanism 4 occupies a small space and has a high accuracy in up and down movement.

[0046] Furthermore, the plurality of reed blades 31 are evenly spaced and radially arranged outward with the core mold cylinder 2 as the center, and the arrangement of the plurality of reed blades 31 is as follows: Figure 5 As shown, the number of the plurality of reed blades 31 can be 2, 3, 4, etc., as long as the purpose of enclosing the core mold tube 2 is achieved, and the plurality of reed blades 31 are arranged around the periphery of the cylindrical tube 22. Optimally, the number of the plurality of reed blades 31 is 8, which can surround the core mold tube 2 as much as possible without causing too many warp yarns on each reed blade 31.

[0047] In the technical solution of the present invention, the second driving structure includes at least one cylinder 61, each cylinder 61 is vertically arranged on the main frame 1, and the output end of the cylinder 61 is connected to the edge of the reed blade 31. The number of at least one cylinder 61 can be 1, 2, 3, etc. Optimally, the number of at least one cylinder 61 is 3. If there are too many cylinders 61, the cost is high. If there are too few, the reed blade 31 will not be stable enough when moving.

[0048] In this embodiment, the second driving mechanism 6 also includes: a plurality of slide rails 62, which are vertically arranged in the limiting cylinder 21, and the bottom end of each slide rail 62 is connected to the top surface of the lower welding plate 41; and a plurality of sliders 63, which correspond one-to-one to the plurality of slide rails 62, and each slider 63 is slidably engaged in the corresponding slide rail 62. The plurality of sliders 63 are arranged one-to-one with the plurality of reed blades 31, and each slider 63 passes through the gap of the side wall of the cylindrical cylinder 22 composed of a plurality of second steel needles 22a and is connected to the end of the corresponding reed blade 31 close to the core mold cylinder 2; wherein, the number of at least one of the cylinders 61 is three, one of which is located below the end of the reed blade 31 close to the core mold cylinder 2 and is connected to the reed blade 31, and the other two cylinders 61 are located below the end of the reed blade 31 away from the core mold cylinder 2 and are connected to the reed blade 31.

[0049] Specifically, if Figure 6 As shown, the second driving mechanism 6 also includes a plurality of slide rails 62 and a plurality of sliders 63. The number of the plurality of slide rails 62 is the same as the number of the plurality of reed blades 31. The end of each reed blade 31 close to the core mold cylinder 2 is vertically slidably engaged with the slide rail 62 through the corresponding slider 63. The number of at least one cylinder 61 is three. The purpose of using such a cylindrical fiber fabric is to make the movement of the reed blade 31 more stable and the reed blade 31 will not shake.

[0050] In this embodiment, the second driving mechanism 6 also includes an annular upper welding plate 64, which is located in the cylindrical tube 22 and above the multiple slide rails 62. The top ends of the multiple slide rails 62 are fixedly connected to the bottom surface of the upper welding plate 64. The upper welding plate 64 serves to stabilize the multiple slide rails 62, so that each slide rail 62 is not easy to shake.

[0051] The technical solution of the present invention also includes a warp feeding mechanism 10, which includes a creel 101, a tension unit 102 and a yarn gathering unit 103 that are close to the main frame 1 from far to near. The warp yarn passes through the creel 101, the tension unit 102 and the yarn gathering unit 103 in sequence and is connected to the shedding mechanism 7.

[0052] Specifically, if Figure 1 、 Figures 8-10As shown, the warp feeding mechanism 10 is a mechanism for feeding the warp yarns to the sheddle lifting mechanism 7. Generally, the warp feeding mechanism 10 includes a bobbin 101 for separating the warp yarns, a tension unit 102 for straightening the warp yarns, and a yarn gathering unit 103 for gathering the warp yarns. The specific structure of the warp feeding mechanism 10 is not limited in this application. In addition to the above-mentioned components, it can also include other components for gathering and straightening the warp yarns. The warp feeding mechanism 10, the core mold cylinder 2, the weft beating mechanism 3, the sheddle lifting mechanism 7 and the weft insertion mechanism 8 together constitute the three-dimensional cylindrical fabric loom 100.
