Abstract
Description
Technical Field
[0001] This utility model relates to the field of secondary reinforcement technology for bridges; specifically, this utility model relates to a tool for scraping and impregnating adhesive used in carbon fiber cloth reinforcement. Background Technology
[0002] Bonding carbon fiber cloth to the underside of bridges is a common method for secondary bridge reinforcement. During the bonding process, because the carbon fiber cloth itself is woven from thousands of fine filaments, there are tiny gaps. Direct bonding may not allow the adhesive to fully penetrate these fiber gaps. Therefore, to improve the bonding effect, a scraping method is needed to allow the impregnating adhesive (resin) to enter the fiber gaps while simultaneously expelling air, preventing air pockets. Current scraping methods mainly rely on manual hand-held scrapers to directly scrape the surface of the carbon fiber cloth. After scraping, a brush is used to apply the adhesive to the surface, and the brush is repeatedly used to scrape the surface to achieve uniform application. This process is inefficient and labor-intensive. Furthermore, the adhesive application effect is greatly affected by manual skill, and there is a lack of standardized scraping methods. Therefore, this application provides a tool for scraping impregnating adhesive used in carbon fiber cloth reinforcement. Utility Model Content
[0003] In view of this, the present invention provides a tool for scraping impregnating adhesive in the reinforcement of carbon fiber cloth, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.
[0004] To achieve the aforementioned objective, this utility model provides a tool for scraping impregnating adhesive used in carbon fiber cloth reinforcement, including a V-shaped adhesive trough for storing adhesive, a roller brush for scraping adhesive by rolling on the surface of carbon fiber cloth inside the V-shaped adhesive trough, a rotary pressing roller group for pressing the carbon fiber cloth synchronously disposed on the front side of the V-shaped adhesive trough, and a handrail for holding the hand between the V-shaped adhesive trough and the rotary pressing roller group.
[0005] In the tool for scraping impregnating adhesive used in carbon fiber cloth reinforcement as described above, optionally, a first brush body and a second brush body are respectively provided on the front and rear sides of the open top of the V-shaped adhesive groove. The first brush body is in a vertical state, and the second brush body is set to be parallel to the rear wall of the V-shaped adhesive groove. The first brush body and the second brush body are used to scrape the carbon fiber cloth.
[0006] In the tool for scraping impregnating adhesive used in carbon fiber cloth reinforcement as described above, the roller brush may optionally include a roller body, both ends of which are provided with roller shafts that rotatably engage with the ends of a V-shaped adhesive groove, the inside of the roller body is provided with an adhesive cavity, an overflow gap is provided between the end of the roller body and the end of the V-shaped adhesive groove, and multiple overflow holes are provided at equal intervals on both ends of the roller body.
[0007] In the tool for scraping impregnating adhesive used in a carbon fiber cloth reinforcement as described above, optionally, the end of the roller extends to the outside of the V-shaped adhesive groove and is fixed with a roller capable of rolling on the underside of the bridge.
[0008] In the tool for scraping impregnating adhesive used in carbon fiber cloth reinforcement as described above, optionally, the top height of the V-shaped adhesive groove is less than the top height of the roller, and the bottom of the V-shaped adhesive groove is set as an arc shape with an inner diameter that matches the outer diameter of the brush roller.
[0009] In the tool for scraping impregnating adhesive used in carbon fiber cloth reinforcement as described above, the rotary roller assembly optionally includes two toothed rotary belts, and a plurality of rotatable rollers are equidistantly arranged between the two toothed rotary belts, and both ends of the toothed rotary belts are meshed with gears.
[0010] The toothed rotary belt is provided with a support plate on its outer side. The belt gear is rotatably mounted on the support plate via a rotating shaft, and the outer end of the roller shaft is rotatably mounted on the support plate. The front end of the handrail is fixedly connected to the support plate.
[0011] In the tool for scraping impregnating adhesive used in carbon fiber cloth reinforcement as described above, optionally, a first gear is coaxially arranged on the outer side of the gear belt, a second gear is meshed on the rear side of the first gear, and the second gear is connected to the roller shaft by a synchronous belt.
[0012] This invention relates to a tool for applying adhesive in carbon fiber cloth reinforcement. This tool effectively combines the processes of air removal, flattening, and adhesive application in a rational manner. It allows for the carbon fiber cloth to be air-depressed and flattened before adhesive application, improving both the efficiency and the effectiveness of the adhesive application. Furthermore, the V-shaped adhesive groove design avoids repeated glue additions and ensures sufficient glue supply to the carbon fiber cloth.

Detailed Implementation
[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] like Figures 1 to 7 As shown, this utility model provides a tool for scraping impregnating adhesive used in carbon fiber cloth reinforcement, including a V-shaped adhesive trough 1 for storing adhesive, a roller brush 2 for scraping adhesive by rolling on the surface of carbon fiber cloth inside the V-shaped adhesive trough 1, a rotary pressing roller group 3 for pressing the carbon fiber cloth synchronously with the front side of the V-shaped adhesive trough 1, and a handrail 4 for holding between the V-shaped adhesive trough 1 and the rotary pressing roller group 3.
[0024] Both the glue and the roller brush 2 are located within the V-shaped glue groove 1, allowing for continuous replenishment of glue to the roller brush 2. The rotary pressing roller assembly 3 and the roller brush 2 are positioned front and rear, directly rolling on the carbon fiber cloth. The rotary pressing roller assembly 3 presses the carbon fiber cloth to achieve air release and further flattening, while the roller brush 2 directly applies glue to the surface of the carbon fiber cloth, further preventing bulging and improving the bonding effect. The handrail 4 spans the V-shaped glue groove 1 and the rotary pressing roller assembly 3 at both ends, serving not only as a handheld device but also effectively connecting the V-shaped glue groove 1 and the rotary pressing roller assembly 3, thus effectively combining the air release and glue application processes. Simultaneously, workers can control the pressure of the rotary pressing roller assembly 3 on the carbon fiber cloth by applying force to the handrail 4, achieving better air release and flattening effects.
[0025] In this embodiment, a first brush body 5 and a second brush body 6 are respectively provided on the front and rear sides of the open top of the V-shaped glue groove 1. The first brush body 5 is vertical, and the second brush body 6 is set parallel to the rear wall of the V-shaped glue groove 1. The first brush body 5 and the second brush body 6 are used to scrape the carbon fiber cloth. The first brush body 5 can further clean the surface of the carbon fiber cloth, remove dust from the carbon fiber cloth, and improve the glue scraping effect of the carbon fiber cloth. The second brush body 6 can further evenly distribute the glue on the surface of the carbon fiber cloth by scraping the surface of the carbon fiber cloth. At the same time, excess glue can flow back into the V-shaped glue groove 1 along the second brush body 6 to collect excess glue.
[0026] In this embodiment, the roller brush 2 includes a roller body 2.1. Both ends of the roller body 2.1 are provided with roller shafts 2.2 that rotatably engage with both ends of the V-shaped glue groove 1. The inside of the roller body 2.1 is provided with a glue cavity 2.3. An overflow gap 7 is provided between the end of the roller body 2.1 and the end of the V-shaped glue groove 1. Both ends of the roller body 2.1 are provided with a plurality of overflow holes 2.4 at equal intervals.
[0027] Specifically, the overflow hole 2.4 is located outside the circumference of the roller 2.2. By setting the glue cavity 2.3, a larger space for storing glue can be provided for the V-shaped groove, increasing the glue storage capacity and avoiding repeated glue additions. The glue in the glue cavity 2.3 can enter the overflow gap 7 through the overflow hole 2.4 and cover the surface of the roller brush 2 through the overflow gap 7, which can replenish the glue to the roller brush 2 in real time. In addition, during the process of the roller brush 2 rolling and applying glue on the carbon fiber cloth, it continuously applies glue to the V-shaped glue groove 1, which can prevent the glue from solidifying, maintain the uniformity and fluidity of the glue, and improve the glue application effect on the carbon fiber cloth.
[0028] Furthermore, the end of the roller 2.2 extends to the outside of the V-shaped glue groove 1 and is fixedly connected to a roller 8 that can roll on the bottom surface of the bridge. By using the roller 8 to roll on the bridge surface, the roller brush 2 is driven to rotate, so that the roller brush 2 can keep in sync with the rotation of the roller 8, ensuring that the roller brush 2 rolls stably on the surface of the carbon fiber cloth, preventing the roller brush 2 from rubbing against the surface of the carbon fiber cloth in some places, which would lead to uneven glue application, and thus ensuring that the roller brush 2 can always uniformly apply glue to the surface of the carbon fiber cloth.
[0029] The top height of the V-shaped adhesive groove 1 is less than the top height of the roller 8, and the bottom of the V-shaped adhesive groove 1 is set as an arc shape with an inner diameter that matches the outer diameter of the brush roller. The roller 8 can stably maintain the distance between the V-shaped adhesive groove 1, the roller brush 2, and the carbon fiber cloth, avoiding excessive compression of the first brush body 5, the second brush body 6, and the roller brush 2.
[0030] In this embodiment, the rotary rolling mill group 3 includes two toothed rotary belts 3.1, and a plurality of rotatable rolling mills 3.2 are equidistantly arranged between the two toothed rotary belts 3.1. Both ends of the toothed rotary belts 3.1 are meshed with gears 3.3.
[0031] A support plate 9 is provided on the outer side of the toothed rotary belt 3.1. A gear 3.3 is rotatably mounted on the support plate 9 via a rotating shaft, and the outer end of the roller 2.2 is rotatably mounted on the support plate 9. The front end of the handrail 4 is fixedly connected to the support plate 9.
[0032] The two support plates 9 are effectively connected as one unit by the handrail 4, thereby ensuring the stability between the rotary roller assembly 3 and the V-shaped rubber groove 1. Two gears 3.3 stably install the toothed rotary belt 3.1 between the two support plates 9, ensuring that the toothed rotary belt 3.1 has stable rotation performance.
[0033] Specifically, in this embodiment, the outer diameter of the roller 3.2 is larger than the width of the toothed rotary belt 3.1, so that the roller 3.2 contacts the surface of the carbon fiber cloth and rolls on the surface of the carbon fiber cloth, while the toothed rotary belt 3.1 moves away from the carbon fiber cloth. The length of the roller 3.2 should be set to be greater than or at least equal to the width of the carbon fiber cloth.
[0034] Furthermore, a first speed-changing gear 10 is coaxially arranged on the outer side of the gear 3.3, and a second speed-changing gear 11 meshes with the rear side of the first speed-changing gear 10. The second speed-changing gear 11 is connected to the roller shaft 2.2 by a synchronous belt 12. By setting the first speed-changing gear 10, the second speed-changing gear 11, and the synchronous belt, the roller 8 can drive the toothed rotary belt 3.1 to rotate in the opposite direction to the rolling direction of the roller 8 during the rolling process. That is, when the roller 8 rolls forward, the toothed rotary belt 3.1 drives the grinding roller 3.2 to rotate in the opposite direction. At this time, the grinding roller 3.2 can press the carbon fiber cloth forward and expel air forward.
[0035] The outer diameter of the second gear 11 is larger than that of the first gear 10, which makes the rotational speed of the toothed rotary belt 3.1 greater than that of the roller 8. This allows the roller 3.2 to roll on the surface of the carbon fiber cloth while also moving forward on the surface of the carbon fiber cloth. This combines rolling and pressing with moving and pushing, improving the efficiency of forward exhaust and thus improving the exhaust and flattening effect of the carbon fiber cloth.
[0036] In summary, the tool for applying impregnating adhesive in carbon fiber cloth reinforcement provided in this embodiment effectively combines the air removal and flattening of carbon fiber cloth with adhesive application, realizing a rational and standardized work process of first air removal, flattening and then applying adhesive, improving the adhesive application effect of carbon fiber cloth, and thus improving the bonding effect of carbon fiber cloth.
[0037] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
