Description

Technical Field

[0001] The present application relates to the technical field of carbon fiber tube processing and manufacturing, and in particular to a carbon fiber tube processing device. Background Art

[0002] Carbon fiber tubes are high-performance composite materials reinforced with carbon fibers. Due to their lightweight, high strength, high stiffness, and corrosion resistance, they are widely used in various industries. Patent publication number CN116728757B discloses a tool for preparing carbon fiber composite tubes. The tool comprises an electric slide, a movable seat, a guide assembly, and a mandrel. The movable seat is mounted on the electric slide, and the guide assembly is mounted on the movable seat. As the mandrel rotates, the movable seat slides on the electric slide, allowing multiple layers of carbon fiber strips to be wound around the mandrel. The mandrel is then removed and heated to produce a carbon fiber tube.

[0003] Since the production of carbon fiber tubes is to wind multiple layers of carbon fiber strips on a core shaft, and then heat and cut the core shaft to form a carbon fiber tube, the length of the carbon fiber tube is limited by the length of the core shaft. The variable range of the length of the carbon fiber tube is small and the applicability is low. In addition, after each carbon fiber tube is produced by the equipment, the core shaft needs to be disassembled and heated, which cannot produce carbon fiber tubes continuously and has low processing efficiency.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0035] A carbon fiber tube processing device, referring to Figure 1 , including a fixing frame 1, a core shaft 2, a feeding mechanism 3, a first braiding and winding machine 4, a soaking mechanism 6, a straight wire coating mechanism 7, a second braiding and winding machine 8, a heating box 9, a demoulding mechanism 10 and a cutting machine 20, one end of the core shaft 2 is fixed on the fixing frame 1 and the other end is extended in the horizontal direction, the core shaft 2 is sequentially provided with a first braiding station, a straight wire station, a soaking station, a second braiding station and a heating and forming station along the length direction, the feeding mechanism 3 is used to feed the first carbon fiber filament, the second carbon fiber filament and the third carbon fiber filament; the first braiding and winding machine 4 is provided at the first braiding station and is used to braid the first carbon fiber filament on the core shaft 2 to form a first braided winding layer; the soaking machine The structure 6 is arranged at the soaking station for soaking the second carbon fiber filaments in resin; the straight wire covering mechanism 7 is arranged at the straight wire station and is used to cover the second carbon fiber filaments soaked in resin on the first braided winding layer to form a straight wire layer; the second braiding winding machine 8 is arranged at the second braiding station and is used to braid the second carbon fiber filaments on the straight wire layer to form a second braided winding layer; the heating box 9 is arranged at the heating and molding station and is passed through by the core shaft 2 and is used to heat the carbon fiber tube; the demoulding mechanism 10 is arranged on the side where the core shaft 2 passes through the heating box 9 and is used to pull the molded carbon fiber tube out of the core shaft 2; the cutting machine 20 is arranged on one side of the demoulding mechanism 10 and is used to cut the pulled out carbon fiber tube.

[0036] In this embodiment, the first braiding and winding machine 4 and the second braiding and winding machine 8 can be a 24-inch braiding machine, a 48-inch braiding machine, a 96-inch braiding machine, or other types of braiding machines. By replacing the first braiding and winding machine 4 and the second braiding and winding machine 8 with different models, carbon fiber tubes of different specifications can be produced. In other embodiments, the first braiding and winding machine 4 and the second braiding and winding machine 8 can be an 8+8 winding machine, which is used to wind the first carbon fiber filaments on the core shaft 2 and the third carbon fiber filaments on the straight filament layer, thereby producing carbon fiber tubes of different specifications and forms.

[0037] In this embodiment, three feeding mechanisms 3 are provided, and the three feeding mechanisms 3 are used to feed the first carbon fiber filament, the second carbon fiber filament and the third carbon fiber filament, respectively, and a dryer 5 is provided next to each feeding mechanism 3. The first carbon fiber filament, the second carbon fiber filament and the third carbon fiber filament coming out of each feeding mechanism 3 are respectively passed into the corresponding dryer 5, and the first carbon fiber filament, the second carbon fiber filament and the third carbon fiber filament are dried by the dryer 5. Through the drying process, the moisture in the first carbon fiber filament, the second carbon fiber filament and the third carbon fiber filament is removed and the hardness and widening performance of the carbon fiber filament are enhanced, and the generation of hair is reduced, thereby improving the quality and consistency of the final product.

[0038] The dried first carbon fiber filaments are transferred to the first braiding and winding machine 4, which braids the first carbon fiber filaments onto the core shaft 2, thereby forming a tubular first braided winding layer. Furthermore, because the demolding mechanism 10 continuously demolds the formed carbon fiber tube, the formed first braided winding layer continuously advances on the core shaft 2.

[0039] At the same time, the second carbon fiber filament is transported to the soaking station, and the second carbon fiber filament is soaked in resin by using the soaking mechanism 6. The second carbon fiber filament after soaking in resin is transported to the straight wire station. At this time, the core shaft 2 on the straight wire station is covered with a first woven winding layer, and the straight wire covering mechanism 7 covers the second carbon fiber filament on the first woven winding layer to form a straight wire layer. Specifically, the second carbon fiber filament is arranged along the length direction of the core shaft 2 to provide longitudinal force support for the formed carbon fiber tube, and at this time the second carbon fiber filament is in contact with the first carbon fiber filament, so that the first carbon fiber filament and the second carbon fiber filament are both stained with resin.

[0040] The straight wire layer moves synchronously with the first braided winding layer. When it moves to the second braiding station, the second braiding winding machine 8 weaves the third carbon fiber wire on the straight wire layer to form a second braided winding layer. Since the second carbon fiber wire is bonded to the third carbon fiber wire, the second carbon fiber wire is also stained with resin. In this embodiment, the weaving directions of the first carbon fiber wire and the third carbon fiber wire are opposite to each other to increase the force-bearing capacity of the molded carbon fiber tube.

[0041] The first braided winding layer, the straight wire layer, and the second braided winding layer are synchronously moved into the heating box 9, where they are heated, thereby hardening the resin and forming a strong bond with the first carbon fiber filaments, the second carbon fiber filaments, and the third carbon fiber filaments, thereby forming a formed carbon fiber tube.

[0042] The demoulding mechanism 10 clamps the formed carbon fiber tube and moves in a direction away from the core shaft 2, so that the formed carbon fiber tube gradually slides off the core shaft 2, thereby achieving demoulding of the formed carbon fiber tube.

[0043] The cutter 20 cuts the demoulded formed carbon fiber tube and cuts the formed carbon fiber tube. The cutter 20 can cut carbon fiber tubes of different lengths according to actual engineering needs, thereby increasing the applicability of the carbon fiber tube processing device.

[0044] When the carbon fiber tube processing device is loaded for the first time, the first carbon fiber filament, the second carbon fiber filament, and the third carbon fiber filament can be pulled backward by a rope. After a portion of the carbon fiber tube is formed, the formed carbon fiber tube can be demolded by the demolding mechanism 10 without the need for rope pulling.

[0045] Reference Figure 2 Furthermore, support plates 41 are provided on both sides of the first braiding and winding machine 4, and each support plate 41 is provided with a plurality of holes 42. The holes 42 on one support plate 41 are used to pass the second carbon fiber filaments, and the holes 42 on the other support plate 41 are used to pass the third carbon fiber filaments. Through the setting of the two support plates 41, the second carbon fiber filaments and the third carbon fiber filaments are supported, thereby reducing the occurrence of collapse of the second carbon fiber filaments and the third carbon fiber filaments.

[0046] Reference Figure 3 The structure of the feeding mechanism 3 is introduced by taking the feeding mechanism 3 for feeding the first carbon fiber filament as an example. The structures of the other feeding mechanisms 3 are exactly the same as this feeding mechanism 3, so they will not be described in detail.

[0047] The feeding mechanism 3 includes a housing 32 and a plurality of feeding rollers 31. The plurality of feeding rollers 31 are rotatably connected to the housing 32. A first carbon fiber filament is wound around each feeding roller 31. Multiple first carbon fiber filaments pass through the housing 32 and are transported to the first braiding and winding machine 4 for braiding. The plurality of feeding rollers 31 are driven to rotate by a motor. The rotation of the feeding rollers 31 and the cooperation with the demolding mechanism 10 continuously pull the formed carbon fiber tube to slide, thereby achieving uninterrupted feeding of the first carbon fiber filaments.

[0048] Reference Figure 4The soaking mechanism 6 includes a soaking table 61, a pressing roller 62 and a mounting frame 63. The soaking table 61 is located directly below the core shaft 2. A soaking tank 611 is provided on the top surface of the soaking table 61. The mounting frame 63 is installed on the soaking table 61. The pressing roller 62 is rotatably connected to the mounting frame 63 and is arranged in the soaking tank 611. The second carbon fiber filament enters the soaking tank 611 and is pressed in the soaking tank 611 by the pressing roller 62. During the movement of the second carbon fiber filament, the friction between the second carbon fiber filament and the pressing roller 62 is reduced due to the rotation of the pressing roller 62, thereby reducing damage to the second carbon fiber filament.

[0049] Furthermore, a plurality of pressing rollers 62 are provided, and the plurality of pressing rollers 62 are rotatably connected to the mounting frame 63 and are arranged parallel to each other and spaced apart from each other, that is, gaps are provided between adjacent pressing rollers 62, and the second carbon fiber filaments are transported to the straight wire coating mechanism 7 through the gaps. Through the provision of the plurality of pressing rollers 62, the plurality of second carbon fiber filaments are dispersed, thereby reducing the situation in which the second carbon fiber filaments located in the middle and wrapped by other second carbon fiber filaments cannot be fully soaked in resin due to the aggregation of the plurality of second carbon fiber filaments, thereby ensuring that each second carbon fiber filament is fully soaked in resin.

[0050] Furthermore, a quick-release buckle 64 is provided on the soaking table 61, and the mounting frame 63 is fixed to the soaking table 61 by the quick-release buckle 64. In this embodiment, a quick-release buckle 64 is provided on both sides of the mounting frame 63, and the mounting frame 63 realizes a detachable connection between the mounting frame 63 and the soaking table 61 through two quick-release buckles 64, thereby facilitating the disassembly, replacement and cleaning of the mounting frame 63. In other embodiments, the mounting frame 63 can also be rotatably connected to the soaking table 61 at one end, and the other end is fixed to the soaking table 61 by the quick-release buckle 64, and the second carbon fiber filament is pressed into the soaking tank 611 by rotation.

[0051] Reference Figure 5 The straight wire covering mechanism 7 includes a covering tube 71 and a first wire dividing plate 72. The first wire dividing plate 72 is provided with a through hole 74 for the core shaft 2 to pass through and wire holes 75 distributed around the through hole 74. The covering tube 71 is sleeved on the core shaft 2 and fixed to the first wire dividing plate 72 through a connecting rod. The covering tube 71 is arranged between the second braiding and winding machine 8 and the first wire dividing plate 72 and there is a gap between the covering tube 71 and the first wire dividing plate 72.

[0052] After being soaked in resin, the second carbon fiber filaments are passed through the plurality of threading holes 75, so that the second carbon fiber filaments are evenly distributed throughout the first braided winding layer. The second carbon fiber filaments are then inserted into the sheathing tube 71, tightly fitting the second carbon fiber filaments to the first braided winding layer, thereby forming a straight filament layer. Specifically, the diameter of the sheathing tube 71 can gradually decrease from the end closest to the first wire dividing plate 72 to the end farther away from the first wire dividing plate 72, so that the second carbon fiber filaments gradually adhere to the first braided winding layer, making the second carbon fiber filaments adhere more gently to the first braided winding layer.

[0053] Furthermore, the straight wire coating mechanism 7 also includes a second wire dividing plate 73, which is arranged between the first wire dividing plate 72 and the soaking mechanism 6. The second wire dividing plate 73 is also provided with a wire threading hole 75 and a through-hole 74 for the core shaft 2 to pass through. The wire threading holes 75 on the second wire dividing plate 73 are distributed on both sides of the through-hole 74. The plurality of second carbon fiber threads are divided into left and right parts by the second wire dividing plate 73, and then the plurality of second carbon fiber threads are arranged around the first woven winding layer by the first wire dividing plate 72. By providing the second wire dividing plate 73, the position change of the plurality of second carbon fiber threads is smoother and easier to convert into a setting around the first woven winding layer.

[0054] In this embodiment, the first dividing plate 72 and the second dividing plate 73 having different numbers of threading holes 75 can be replaced to produce carbon fiber tubes of different specifications.

[0055] Reference Figure 6 The demolding mechanism 10 includes a machine 101, a horizontal moving member (not shown), and a clamping assembly 102. The horizontal moving member is fixed to the machine 101, and the clamping assembly 102 is fixed to the output end of the horizontal moving member. The horizontal moving member drives the clamping assembly 102 to move along the length of the core shaft 2. The clamping assembly 102 clamps the formed carbon fiber tube. When the clamping assembly 102 moves away from the core shaft 2, it drives the formed carbon fiber tube to move, thereby separating the formed carbon fiber tube from the core shaft 2 and achieving demolding of the formed carbon fiber tube. In this embodiment, the horizontal moving member is a telescopic cylinder. In other embodiments, the horizontal moving member can adopt a horizontal moving guide rail, a telescopic cylinder, an electric telescopic rod, or other structures.

[0056] Furthermore, at least two horizontal moving members and clamping assemblies 102 are provided, and each clamping assembly 102 is installed at the output end of the corresponding horizontal moving member. In this embodiment, two horizontal moving members and two clamping assemblies 102 are used as an example for description.

[0057] The following two horizontal moving members are named as the first horizontal moving member and the second horizontal moving member, and the two clamping assemblies 102 are named as the first clamping assembly 102 and the second clamping assembly 102. The first clamping assembly 102 is installed at the output end of the first horizontal moving member, and the second clamping assembly 102 is installed at the output end of the second horizontal moving member. The first horizontal moving member is closer to the core shaft 2 than the second horizontal moving member.

[0058] During demoulding, the first clamping assembly 102 clamps the formed carbon fiber tube and drives the formed carbon fiber tube to move away from the core shaft 2 through the first horizontal moving member. When the first horizontal moving member is about to reach the limit of the moving range, the second clamping assembly 102 clamps the formed carbon fiber tube and has the same movement speed as the first horizontal moving member. After the second clamping assembly 102 clamps the formed carbon fiber tube, the first clamping assembly 102 releases the clamping of the formed carbon fiber tube and is reset under the drive of the first horizontal moving member. It then re-clamps the formed carbon fiber tube and drives the formed carbon fiber tube to move away from the core shaft 2. At the same time, the second clamping assembly 102 releases the clamping of the formed carbon fiber tube and is reset under the drive of the second horizontal moving member. The above process is repeated to achieve continuous demoulding of the formed carbon fiber tube.

[0059] Specifically, when the second clamping assembly 102 is exchanged with the first clamping assembly 102, the second moving member first drives the second clamping assembly 102 to move at a speed that is the same as the speed at which the first moving member drives the first clamping assembly 102 to move, and then the second clamping assembly 102 clamps the formed carbon fiber tube, and the first clamping assembly 102 releases the clamping of the formed carbon fiber tube.

[0060] The clamping assembly 102 includes a frame 1021, a base plate 1022, a pressure plate 1023, and a driver 1024. The frame 1021 is fixedly connected to the output end of the horizontal moving member. The base plate 1022 and the pressure plate 1023 are mounted on the frame 1021. The driver 1024 is fixed to the frame 1021 and is used to drive the pressure plate 1023 to move away from or toward the base plate 1022. In this embodiment, the pressure plate 1023 is slidably connected to the frame 1021, and the base plate 1022 is fixedly connected to the frame 1021. By moving the pressure plate 1023 toward the base plate 1022, the base plate 1022 and the pressure plate 1023 clamp the formed carbon fiber tube. In this embodiment, the driver 1024 is a telescopic oil cylinder. In other embodiments, the telescopic member can also be a telescopic cylinder or an electric telescopic rod or other structures.

[0061] Furthermore, grooves adapted to the carbon fiber tubes are provided on the bottom plate 1022 and the pressing plate 1023 , so that the pressing plate 1023 and the bottom plate 1022 can clamp the carbon fiber tubes more tightly.

[0062] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
