Description

Technical Field

[0001] This utility model relates to the field of surface finishing device technology, and in particular to a carbon fiber surface finishing device. Background Technology

[0002] Carbon fiber is a new type of fiber material with high strength and high modulus, containing more than 95% carbon. However, the low surface energy of carbon fiber, poor resin wettability, and poor interfacial adhesion between the two phases result in low interlaminar shear strength of the composite material, which affects the overall performance of the composite material and restricts the further promotion and application of carbon fiber in the field of advanced composite materials. In order to improve the performance of carbon fiber reinforced resin matrix composites, the surface of carbon fiber must be modified to improve the adhesion between carbon fiber and other materials. The existing surface modification device is a device for improving and modifying the surface of carbon fiber, with the aim of obtaining carbon quantum dots to achieve surface treatment, which is beneficial to improving the specific binding with bisphenol A.

[0003] According to the authorized patent application No. 202421342986.6, which discloses an in-situ surface finishing device for large-tow carbon fibers, existing finishing devices require the large-tow carbon fibers to be gathered by a bundling ring and re-entered for finishing when decorating the surface of carbon fibers. Therefore, when the large-tow carbon fibers are gathered and pulled inside the bundling ring, they come into contact with the inner surface of the bundling ring and rub against each other during pulling. This friction can easily cause damage, reduce the finishing effect, and affect the convenience of the finishing device in preventing friction and rolling protection inside the bundling ring during the finishing process of carbon fiber surface finishing. To address this issue, this utility model proposes a carbon fiber surface finishing device. Utility Model Content

[0004] This utility model provides a solution to the technical problem that existing technologies suffer from the problem that when large tow carbon fibers are concentrated and pulled inside a bundling ring, they come into contact with each other on the inner surface of the bundling ring and generate friction during pulling, which can easily cause damage and reduce the finishing effect. The present utility model provides a carbon fiber surface finishing device to overcome the above-mentioned defects of the prior art.

[0005] To achieve the above objectives, this utility model provides a carbon fiber surface finishing device, comprising a finishing device body, which includes a carbon fiber roller frame, large tow carbon fibers, and a take-up roller assembly. Both the carbon fiber roller frame and the take-up roller assembly have bundled rings on their sides, and the large tow carbon fibers penetrate the interior of the carbon fiber roller frame and the take-up roller assembly. Three sets of conveying rollers are in drive contact on one side of the bundled rings. A heating roller assembly and a surface oxidation heating circuit are sequentially arranged at the ends of the conveying rollers. The finishing device body also includes:

[0006] An anti-friction rolling mechanism is provided, and the anti-friction rolling mechanism includes a limiting component disposed inside the bundle ring, wherein an elastic connecting component is disposed inside the limiting component, and a rolling component is disposed inside the elastic connecting component.

[0007] A cleaning mechanism, comprising a mounting assembly disposed at the end of a large tow carbon fiber located on the side of a carbon fiber roller frame, wherein a cleaning assembly is disposed inside the mounting assembly, and a feeding assembly is disposed on one side of the cleaning assembly located on the side of the mounting assembly.

[0008] Preferably, an in-situ modifier impregnation spray plate is provided on one side of the surface oxidation heating circuit, and a reaction furnace is provided on one side of the in-situ modifier impregnation spray plate. The large tow carbon fiber passes through the interior of the in-situ modifier impregnation spray plate and the reaction furnace. Support conveying rollers are provided at the ends of both the in-situ modifier impregnation spray plate and the reaction furnace, and the surface of the large tow carbon fiber is in contact with the surface of the support conveying roller.

[0009] Preferably, the limiting component includes limiting grooves formed on both sides inside the cluster ring, and the limiting grooves and the interior of the cluster ring are an integral structure.

[0010] Preferably, the elastic connection assembly includes a limiting seat that is limited and connected inside the limiting groove, and a compression spring is fixed at the connection between the surface of the limiting seat and the inner surface of the limiting groove.

[0011] Preferably, the rolling assembly includes a rolling groove formed inside the limiting seat, and a pressure roller rolls inside the rolling groove.

[0012] Preferably, the mounting assembly includes a frame disposed on one side of the carbon fiber roller frame on the outer surface of the large tow carbon fiber, the surface of the frame being integrally disposed on two mounting seats.

[0015] The beneficial effects of this utility model are:

[0016] In use, this invention employs an anti-friction rolling mechanism to elastically press the limiting seat and the pressure roller together. This allows the two pressure rollers to press the large tow carbon fiber into contact with the surface of the pressure roller. Therefore, during the finishing process, when the large tow carbon fiber is pulled inside the bundling ring, it contacts the surface of the pressure roller and drives the pressure roller to roll. This facilitates smooth pulling and prevents friction from occurring when the large tow carbon fiber is bundled inside the bundling ring. This improves the convenience of the finishing device in preventing friction and rolling during the finishing process of the large tow carbon fiber inside the bundling ring.

[0028] Please see Figures 1 to 6 This utility model provides a carbon fiber surface finishing device, including a finishing device body 100. The finishing device body 100 includes a carbon fiber roller frame 101, a large tow carbon fiber 102, and a gathering roller group 109. Both the carbon fiber roller frame 101 and the gathering roller group 109 are provided with a gathering ring 103 on their sides. The large tow carbon fiber 102 passes through the interior of the carbon fiber roller frame 101 and the gathering roller group 109. Three sets of conveying rollers 104 are in transmission contact on one side of the gathering ring 103. The end of the conveying roller 104 is provided with a heating roller group 105 and a surface oxidation heating circuit 106 in sequence.

[0029] An in-situ modifier impregnation spray plate 107 is provided on one side of the surface oxidation heating circuit 106, and a reaction furnace 108 is provided on one side of the in-situ modifier impregnation spray plate 107. Large tow carbon fiber 102 penetrates the interior of both the in-situ modifier impregnation spray plate 107 and the reaction furnace 108. Support conveying rollers 1081 are provided at the ends of both the in-situ modifier impregnation spray plate 107 and the reaction furnace 108. The surface of the large tow carbon fiber 102 contacts the surface of the support conveying rollers 1081. The large tow carbon fiber 102 is modified by the main body 100 of the modification device. The purpose of surface modification of the large tow carbon fiber 102 is to obtain carbon quantum dots to achieve surface treatment, which is beneficial to improving the specific binding with bisphenol A. The main body 100 of the modification device also includes:

[0030] The anti-friction rolling mechanism includes a limiting component disposed inside the bundle ring 103, an elastic connecting component disposed inside the limiting component, and a rolling component disposed inside the elastic connecting component. The main body 100 of the finishing device can finish the large tow carbon fiber 102. When the large tow carbon fiber 102 is pulled inside the bundle ring 103, it is subjected to anti-friction rolling treatment by the anti-friction rolling mechanism, which is not easy to cause friction damage.

[0031] In order to facilitate the installation of the limiting and clamping mechanism through the limiting component, in this embodiment, preferably, the limiting component includes limiting grooves 1032 formed on both sides inside the bundle ring 103. The limiting grooves 1032 and the interior of the bundle ring 103 are an integral structure, and the limiting seat 1031 can be installed inside the bundle ring 103 through the limiting grooves 1032, which facilitates the installation and limiting operation.

[0032] In order to facilitate the elastic pressing of the limiting seat 1031 and the pressure roller 1034 through the elastic connecting assembly, in this embodiment, preferably, the elastic connecting assembly includes a limiting seat 1031 that is limited and connected inside the limiting groove 1032. A compression spring 1033 is fixed at the connection between the surface of the limiting seat 1031 and the inner surface of the limiting groove 1032. The compression spring 1033 can deform to drive the limiting seat 1031 to slide inside the limiting groove 1032, thereby driving the pressure roller 1034 to perform elastic pressing operation.

[0033] In order to facilitate the smooth pulling of the large tow carbon fiber 102 inside the bundle ring 103 by means of the rolling assembly and to reduce friction, in this embodiment, preferably, the rolling assembly includes a rolling groove 1035 opened inside the limiting seat 1031, and a pressure roller 1034 rolls inside the rolling groove 1035. The pressure roller 1034 can elastically press against the surface of the large tow carbon fiber 102, and the contact roller 1034 is rolled to prevent friction when the large tow carbon fiber 102 is pulled inside the bundle ring 103.

[0034] The cleaning mechanism includes an installation component located at the end of the large tow carbon fiber 102 on the side of the carbon fiber roller frame 101. The installation component contains a cleaning component, and a feeding component is located on one side of the cleaning component on the side of the installation component. Before the finishing device body 100 finishes finishing the large tow carbon fiber 102, the cleaning mechanism cleans the large tow carbon fiber 102 and then finishes it again, thereby improving the finishing effect.

[0035] In order to facilitate the installation and cleaning of the flexible brush 1025 by means of the mounting component, in this embodiment, preferably, the mounting component includes a frame 1021 disposed on one side of the carbon fiber roller frame 101 on the outer surface of the large tow carbon fiber 102. The surface of the frame 1021 is integrally disposed on two mounting seats 1022. The frame 1021 can be fixedly installed at the end by means of the mounting seats 1022, which facilitates installation, cleaning and use before finishing.

[0036] In order to facilitate the finishing process after cleaning the surface of the large tow carbon fiber 102 using the cleaning component, in this embodiment, preferably, the cleaning component includes mounting grooves 1023 formed on both sides inside the frame 1021. A flexible brush 1025 is fixed inside the mounting groove 1023 by screws, and the surface of the flexible brush 1025 is in contact with the surface of the large tow carbon fiber 102. The large tow carbon fiber 102 can be cleaned inside the frame 1021 by contact with the flexible brush 1025, which facilitates the finishing process after cleaning and improves the finishing effect.

[0037] In order to facilitate the discharge of cleaned dirt to the outside through the feeding assembly, in this embodiment, preferably, the feeding assembly includes two feeding arc surfaces 1024 formed on one side of the mounting groove 1023 inside the carbon fiber roller frame 101, and the two feeding arc surfaces 1024 are symmetrically arranged. After cleaning the dirt on the surface of the large tow carbon fiber 102, the dirt at the bottom can be discharged through the feeding arc surfaces 1024, and the dirt at the end of the large tow carbon fiber 102 on the upper surface can be discharged through the bending angle.

[0038] The working principle and usage process of this utility model are as follows: In use, this carbon fiber surface modification device sequentially passes large tow carbon fibers 102 through a carbon fiber roller frame 101, a bundling ring 103, a heating roller assembly 105, a surface oxidation heating circuit 106, an in-situ modification agent impregnation spray plate 107, a reaction furnace 108, and a take-up roller assembly 109. After the large tow carbon fibers 102 are opened by the carbon fiber roller frame 101 and bundled inside the bundling ring 103, they pass through the heating roller assembly 105 again. The high temperature effectively removes the epoxy resin remaining on the surface of the original tow. When the large tow carbon fibers 102 pass through the surface oxidation heating circuit 106, the surface oxidation of the large tow carbon fibers 102 is completed in an air atmosphere. When the towed carbon fiber 102 is impregnated by the in-situ modifier spray plate 107, the spray holes on the plate spray an organic coating. This spray can effectively form an organic coating on the surface of the oxidized large towed carbon fiber 102. Then, the large towed carbon fiber 102 is heated by the reactor 108. This heating process can remove the solvent and promote the in-situ surface modification of the carbon fiber, thereby facilitating the modification treatment of the large towed carbon fiber 102 by the main body 100 of the modification device. The purpose of the surface modification of the large towed carbon fiber 102 is to obtain carbon quantum dots to achieve surface treatment, which is beneficial to improve the specific binding with bisphenol A (the above modification steps are all prior art and disclosed in the authorized patents, and will not be described in detail here).

[0039] Then, when the large tow carbon fiber 102 is being finished, the large tow carbon fiber 102 is bundled inside the bundling ring 103. At this time, the compression spring 1033 deforms and drives the limiting seat 1031 to elastically connect inside the limiting groove 1032 until the limiting seat 1031 and the pressure roller 1034 are elastically pressed together. This makes the two pressure rollers 1034 elastically press the large tow carbon fiber 102 to contact the surface of the pressure roller 1034. Therefore, when the large tow carbon fiber 102 is pulled inside the bundling ring 103 during the finishing process, it contacts the surface of the pressure roller 1034 and drives the pressure roller 1034 to roll. This facilitates smooth pulling and prevents friction when the large tow carbon fiber 102 is bundled inside the bundling ring 103. This improves the convenience of the finishing device body 100 in preventing friction and rolling protection when the large tow carbon fiber 102 is being pulled inside the bundling ring 103 during the finishing process.

[0040] Finally, before the finishing device body 100 finishes the large tow carbon fiber 102 and before the carbon fiber roller frame 101 is opened, the frame 1021 is fixedly installed in the position of use by the mounting base 1022. The large tow carbon fiber 102 penetrates the inside of the frame 1021 and contacts the surface of the flexible brush 1025. Before the finishing is opened, the large tow carbon fiber 102 passes through the inside of the frame 1021 and is cleaned by the flexible brush 1025. The frame 1021 is extremely flexible and the material used for cleaning the large tow carbon fiber 102 is not likely to cause damage to the large tow carbon fiber 102 during cleaning. After cleaning, the dirt on the lower surface is led out to the outside through the guide arc surface 1024. The dirt on the upper surface of the large tow carbon fiber 102 is led out to the outside by tilting the top of the large tow carbon fiber 102 at an angle. This facilitates cleaning before finishing, effectively finishes the finishing process, and improves the convenience and finishing effect of the finishing device body 100 in cleaning the surface of the large tow carbon fiber 102 during finishing.

[0041] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
