Description

Technical Field

[0001] This utility model relates to the field of filament weaving technology, specifically to a high-efficiency carbon fiber filament weaving equipment. Background Technology

[0002] Traditional filament weaving processes mainly employ single-axis winding or hand weaving, which suffer from problems such as low efficiency, poor product consistency, and difficulty in achieving multi-material composite weaving.

[0003] Existing carbon fiber filament braiding equipment typically uses a fixed feeding structure, which can only achieve continuous winding of a single filament and cannot meet the needs of multi-material composite braiding. In addition, the filament feeding mechanism of traditional equipment mostly relies on a single slide rail or gear and rack transmission, which has defects such as low motion accuracy, easy wear, and insufficient stability. This leads to uneven filament tension during the braiding process, affecting the quality of the finished product. Some improved equipment attempts to use a multi-axis linkage structure, but due to the lack of reasonable motion decoupling design, it is prone to vibration when running at high speed, which limits the improvement of braiding efficiency.

[0004] Therefore, there is an urgent need to develop a new type of high-efficiency weaving equipment that can simultaneously weave multiple filaments of different materials, thereby meeting the modern industrial demand for high-performance composite filaments. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a high-efficiency carbon fiber filament weaving device that can weave carbon fiber filaments and simultaneously weave multiple filaments of different types and materials.

[0006] The technical problem to be solved by this utility model is achieved through the following technical solution: a high-efficiency carbon fiber filament weaving device, including a device body, which has;

[0007] A three-jaw chuck, located on top of the device body, is used to provide rotational power for the rod-shaped body.

[0008] The sliding mechanism is located on the equipment body below the three-jaw chuck. It includes a screw and nut assembly and a slide rail and slider assembly. The screw of the screw and nut assembly and the slide rail of the slide rail and slider assembly are arranged in a direction parallel to the axis of the three-jaw chuck.

[0009] The bottom left and right sides of the material box are fixedly connected to the top surface of the nut in the screw and nut assembly and the top surface of the slider in the slide rail and slider assembly, thereby supporting the material box and allowing it to move. Several material rods with filaments wound around them are vertically and rotatably installed on the inner wall of the bottom of the material box. A material cover is provided on the top of the material box, and a material passage hole for the filaments to pass through is opened on the material cover.

[0011] The power output end of the rotary power mechanism is connected to the end of the screw via a coupling.

[0012] The outer circumferential surfaces of both ends of the screw are mounted on the middle part of the equipment body through bearing seats;

[0013] Two nuts are provided, one in front of the other, and are screwed onto the screw rod at intervals. The top surfaces of the two nuts are welded to the bottom surface of the material box for fixation.

[0014] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the high-efficiency weaving equipment for carbon fiber filaments described above, wherein the slide rail and slider assembly includes a slide rail and a slider.

[0016] The slider is fitted with a linear bearing in the middle, and the inner ring of the linear bearing is sleeved on the outer circumferential surface of the slide rail.

[0017] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the high-efficiency weaving equipment for carbon fiber filaments described above has rounded corners on the top and bottom edges of the inner circumferential surface of the feed hole, thereby increasing the contact surface between the inner circumferential surface of the feed hole and the filament.

[0018] The technical problem to be solved by this utility model can also be achieved through the following technical solution: in the high-efficiency weaving equipment for carbon fiber filaments described above, the number of material passage holes is set in a one-to-one correspondence with the number of material rods, and the material passage holes are located directly above the material rods.

[0019] Compared with the prior art, the beneficial technical effects of this utility model are:

[0020] (1) The material box is equipped with multiple material rods wound with different types of filaments, which can simultaneously accommodate material rods wound with filaments of different materials, thus realizing the synchronous weaving of multiple heterogeneous filaments such as carbon fiber and other composite materials, avoiding the limitations of single material weaving.

[0021] (2) The screw and nut assembly and the slide rail and slider assembly work together to ensure the transmission rigidity of the axial movement of the material box on the one hand, and to provide stability when the material box moves on the other hand.

[0026] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0027] Example 1, referring to Figure 1-2 A high-efficiency carbon fiber filament weaving device, comprising a device body 1, which is formed as a roughly square frame structure, having on it;

[0028] The three-jaw chuck 2 is located on the top of the equipment body 1. The top of the equipment body 1 has a main shaft and a rotational power mechanism that drives the main shaft to rotate, such as a geared motor. The three-jaw chuck 2 is directly connected to the main shaft. Its installation method and operating principle are existing technologies, so its specific principle will not be described in detail here. It is used to provide rotational power for the rod-shaped body 3. The rod-shaped body 3 can be a cylindrical structure. Its purpose is to wind different types of filaments 4. After the filaments 4 are wound, we usually heat the rod-shaped body 3 to shape the filaments 4. After shaping, the filaments 4 can be separated from the rod-shaped body 3. The size and specifications of the rod-shaped body 3 can be selected according to the usage requirements.

[0029] The sliding mechanism is located on the equipment body 1 below the three-jaw chuck 2. It includes a screw and nut assembly and a slide rail and slider assembly. The screw 5 of the screw and nut assembly and the slide rail 6 of the slide rail and slider assembly are arranged in a direction parallel to the axis of the three-jaw chuck 2.

[0030] The screw and nut assembly includes a rotary power mechanism 7, a screw 5, and nuts 8, all located in the middle of the equipment body 1. The power output end of the rotary power mechanism 7 is connected to the end of the screw 5 via a coupling. The rotary power mechanism 7 can be a servo motor as described in the prior art. The outer circumferential surfaces of both ends of the screw 5 are mounted on the middle of the equipment body 1 via bearing seats. Two nuts 8 are arranged one in front of the other, and the two nuts 8 are screwed onto the screw 5 at intervals. The top surfaces of the two nuts 8 are welded and fixed to the bottom surface of the material box.

[0031] The slide rail and slider assembly includes a slide rail 6 and a slider 9; the slide rail 6 has support seats fixedly provided on the outer peripheral surfaces at both ends. The support seats are formed into a roughly square plate structure and can be bolted to the equipment body 1. The bottom surface of the support seats is fixed on the middle part of the equipment body 1; the slider 9 has a linear bearing embedded in the middle part, and the inner ring of the linear bearing is sleeved on the outer peripheral surface of the slide rail 6.

[0032] The material box 10 is formed into a roughly square box structure. The left and right sides of its bottom surface are fixedly connected to the top surface of the nut 8 in the screw and nut assembly and the top surface of the slider 9 in the slide rail and slider assembly, thereby supporting the material box 10 and allowing it to move. Several material rods 11 with filaments 4 wound around them are vertically and rotatably installed on the inner wall of the bottom surface of the material box 10. The connecting rods are formed into roughly cylindrical rod structures. Their bottoms are rotatably installed on the inner wall of the bottom surface of the material box 10 through a rotary bearing. A material cover 12 is provided on the top of the material box 10. The material cover 12 is formed into a roughly square cover structure. A material passage hole 13 for the filaments 4 to pass through is opened on the material cover 12. The material passage hole 13 can be a circular through hole. The number of material passage holes 13 corresponds one-to-one with the number of material rods 11. The material passage holes 13 are located directly above the material rods 11.

[0033] To prevent the inner circumferential edge of the feed hole 13 from being too sharp and thus damaging the filament 4 during the winding process, the top and bottom edges of the feed hole 13 are rounded to increase the contact area between the inner circumferential surface of the feed hole 13 and the filament 4.

[0034] The operating principle of the high-efficiency carbon fiber filament weaving equipment in Example 1 is as follows:

[0035] (1) Equipment preparation stage: Clamp the rod 3 to be wound on the three-jaw chuck 2. Ensure that the rod 3 is coaxial with the main shaft through the self-centering function of the chuck to avoid eccentric vibration during rotation. Open the material cover 12 of the material box 10 and install the material rod 11 with different materials of filament 4 such as carbon fiber and metal wire vertically on the rotary bearing at the bottom of the material box 10 to ensure that each material rod 11 can rotate freely. In order to facilitate the disassembly between the material rod 11 and the inner ring of the rotary bearing, a connecting key can be fixed at the bottom of the material rod 11. The rotary bearing can be selected with a keyway in the inner ring that is used to cooperate with the connecting key. After the material rod 11 is installed, close the material cover 12 and let the filament 4 pass through the corresponding material hole 13. Check the smoothness of each filament 4 when passing through the material hole 13. Use the rounded corner structure of the hole edge to reduce friction and prevent damage to the surface of the filament 4.

[0036] (2) Weaving parameter settings: We set the moving speed and stroke of the screw and nut assembly so that the material box 10 moves along the axial direction of the slide rail 6 and matches the spindle speed to form the required spiral winding pitch. The specific parameters can be customized according to the different specifications of the rod 3. The corresponding spindle speed and the speed of the power output end of the rotating power mechanism 7 can be controlled and adjusted by the existing PLC controller to meet the normal displacement feed of the material box 10, so as to achieve synchronous operation of the spindle and the screw 5.

[0037] (3) Filament 4 winding process: When the material box 10 moves, the filament 4 on each material rod 11 is continuously released from the material hole 13 and is evenly wound on its surface under the rotation of the rod 3. The linear bearing of the slide rail slider assembly ensures that the material box 10 moves without jamming. The double nut 8 structure prevents displacement error caused by the reverse clearance of the screw 5. Multiple filaments 4 of different materials are composite woven through the synchronous filament feeding of the material box 10, such as the mixed winding of carbon fiber and copper wire. After the weaving is completed, the rod 3 in the material box 10 can be taken out and finally sent into the oven for heat setting, so that the filament 4 is heat-set and cured. After the filament 4 is heat-set, the filament 4 can be easily separated from the rod 3 by man.
