Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber cloth production, in particular to a resin coating device for carbon fiber cloth. Background Art

[0002] Carbon fiber cloth is a carbon fiber composite material formed by unidirectional carbon fiber filaments and matching impregnated glue. It can constitute a complete carbon fiber cloth sheet reinforcement system. It is suitable for reinforcement projects that deal with increased building loads, changes in engineering functions, material aging, concrete strength grades lower than the design value, structural crack treatment, and repair and protection of components serving in harsh environments.

[0003] During the production of carbon fiber cloth, epoxy resin glue needs to be coated on the carbon fiber filaments. In the existing gluing equipment, such as the gluing equipment for carbon fiber cloth production disclosed in patent CN208742924U, when in use, the motor drives the belt and pulley to operate. During the transmission process of the conveyor belt, the glue box continuously pours glue onto the carbon fiber cloth through the slurry outlet. When the carbon fiber cloth passes through the brush, the brush can play the role of brushing and printing evenly. When passing through the scraper, the scraper can scrape off the excess glue on the carbon fiber cloth and smooth its surface, thereby completing the gluing work of the carbon fiber cloth.

[0004] However, after the gluing is completed, the above-mentioned gluing equipment cannot rewind the carbon fiber cloth immediately because the epoxy resin glue takes a certain amount of time to cure. It can only be rewound after it is naturally cured or cured by special curing equipment, so the production efficiency is low. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0025] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0026] like Figure 1As shown, the resin coating device for carbon fiber cloth in this embodiment includes a frame 1, an unwinding roller 2, a winding roller 3, a winding motor 4, a first guide roller 5, a second guide roller 6, a third guide roller 7, a gluing mechanism 8 and a UV curing light box 9. The unwinding roller 2 and the winding roller 3 are respectively arranged on both sides of the frame 1 and at a lower position to facilitate the replacement of the roll; the first guide roller 5, the second guide roller 6 and the third guide roller 7 are arranged in sequence above the frame 1, the gluing mechanism 8 and the UV curing light box 9 are arranged in sequence above the frame 1 and between the second guide roller 6 and the third guide roller 7. A coating roller 10 and a support roller 11 are also provided between the gluing mechanism 8 and the UV curing light box 9. The coating roller 10 and the support roller 11 are symmetrically arranged above the frame 1 in the longitudinal direction.

[0027] like Figure 2 As shown, the winding motor 4 is disposed on one side of the frame 1 and is in transmission connection with the winding roller 3. A first gear 31 is disposed at one end of the winding roller 3. The winding motor 4 is in transmission connection with a second gear 41. The first gear 31 meshes with the second gear 41. The winding motor 4 drives the second gear 41 and the first gear 31 to rotate, thereby driving the winding roller 3 to rotate, thereby winding the carbon fiber cloth.

[0028] like Figure 3 As shown, the gluing mechanism 8 includes a glue box 81, a blanking plate 82 and a gate plate 83. The glue box 81 is supported by a first bracket 84 and is arranged above the frame 1. A cover plate 85 is provided at the feeding port on the top of the glue box 81. The blanking plate 82 is arranged at the discharge port of the glue box 81 in a downwardly inclined manner. A discharge grid 86 is provided laterally at the discharge port. The discharge grid 86 can evenly distribute the epoxy resin glue on the blanking plate 82 and flow along the blanking plate 82 to the carbon fiber cloth below.

[0029] A slide rail 87 is provided on the front outer wall of the glue box 81, and the back of the gate plate 83 is slidably connected to the slide rail 87 through a slider. A locking screw 88 is provided on the front side of the gate plate 83. The end of the locking screw 88 passes through the gate plate 83 and abuts against the front outer wall of the glue box 81, thereby locking the position of the gate plate 83 to achieve adjustment of the discharge port width and thereby change the glue discharge amount.

[0030] An electric heating plate 89 is provided at the bottom of the blanking plate 82. When the ambient temperature is low, the electric heating plate 89 can be started to heat the blanking plate 82, so that the heat is transferred to the epoxy resin glue to improve the fluidity of the epoxy resin glue and thereby improve the uniformity of the glue coating.

[0031] The UV curing light box 9 is set on the frame 1 through the second bracket 91. A plurality of UV lamps are arranged in the UV curing light box 9. The UV curing light box 9 uses a photoinitiator to generate excited ecological molecules under ultraviolet irradiation, decompose them into free radicals or ions, and make the unsaturated organic matter undergo chemical reactions such as polymerization, grafting, and cross-linking, thereby achieving the purpose of curing.

[0032] It should be noted that the UV curing light box 9 only cures the epoxy resin glue appropriately to the extent that it does not flow or drip, but does not completely dry it.

[0033] The first guide roller 5 is arranged on the frame through the third bracket 51. Figure 4 As shown, a slide groove 52 is provided inside the third bracket 51, and the first guide roller 5 is slidably set in the slide groove 52 through a slide seat 53. A gas spring 54 is also provided in the slide groove 52. The bottom of the gas spring 54 is set on the frame 1, and the piston rod at the top is fixedly connected to the slide seat 53.

[0034] During the operation of the carbon fiber cloth, the gas spring 54 is appropriately compressed to provide tensioning force and buffer space for the carbon fiber cloth, thereby preventing the carbon fiber cloth from being excessively stretched.

[0035] When the utility model is used, the carbon fiber cloth roll with the release paper laid on the bottom in advance is placed on the unwinding roller 2, and one end is pulled to the winding roller 3, and then the winding motor 4 drives the winding roller 3 to rotate, driving the carbon fiber cloth and the release paper to run synchronously toward the side of the winding roller 3.

[0036] During the operation of the carbon fiber cloth, the epoxy resin glue flows from the blanking plate 82 to the surface of the carbon fiber cloth, and then the glue is evenly spread and squeezed into the gaps of the carbon fiber tows through the coating roller 10 and the supporting roller 11. The glued carbon fiber cloth is then quickly cured by the UV curing light box 9 to prevent the glue from flowing, which facilitates the subsequent timely winding, thereby improving the gluing efficiency of the carbon fiber cloth.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. In addition, the technical solutions of the various embodiments may be combined with each other, but this must be based on the fact that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is inconsistent or cannot be implemented, it shall be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
