Description

Technical Field

[0001] This utility model applies to the technical field of product adhesive coating, and particularly relates to a fiberglass cloth adhesive coating mechanism. Background Technology

[0002] The "Global Wind Power Industry Chain Technology Development White Paper (2023)" points out that the annual growth rate of composite material usage in the wind power industry has reached 12.3%. Among them, glass fiber reinforced materials (glass fiber cloth), as the core substrate of blades, have their surface treatment processes directly affecting the interlaminar shear strength (ILSS) of the composite material. Currently, the manufacturing industry faces a dual challenge: on the one hand, data from the International Renewable Energy Agency (IRENA) shows that labor costs account for 28% of the manufacturing cost of wind power components; on the other hand, the EU REACH regulation has raised the control standard for volatile organic compound (VOC) emissions to 150 mg / m³, making traditional adhesive coating processes insufficient to meet environmental requirements (data source: IRENA 2022 Annual Report). Manual application of adhesive faces several technical bottlenecks: First, the high viscosity of epoxy resin adhesive leads to insufficient precision in controlling the coating amount during manual operation (fluctuation range of ±15%), directly affecting the interlayer bonding strength of the composite material; second, the process environment poses occupational health risks due to excessive concentrations of volatile organic compounds (VOCs); third, existing adhesive application fixtures retain 12-18% of the raw material consumption, and cleaning and maintenance account for 30% of the production cycle. If a simple, precisely controllable adhesive amount could be designed for fiberglass cloth coating, ensuring dynamic matching between the fiberglass cloth's travel speed and the amount of adhesive applied, these problems could be solved. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a fiberglass cloth coating mechanism with a simple structure, which can accurately control the amount of adhesive and ensure the dynamic matching between the fiberglass cloth traveling speed and the amount of adhesive.

[0007] Furthermore, the fiberglass cloth assembly includes a rotating shaft support block, a fiberglass cloth roll, and a rotating motor.

[0019] like Figures 1 to 6 As shown, in this embodiment, the present invention includes a support frame 1, a fiberglass cloth assembly 2, and an adhesive coating assembly 3. The fiberglass cloth assembly 2 and the adhesive coating assembly 3 are respectively disposed on both sides of the support frame 1. The adhesive coating assembly 3 includes an adhesive coating base plate 31 and a fixing plate 32. A first adhesive coating component 33 and a second adhesive coating component 34 are respectively disposed on one side of the adhesive coating base plate 31 and the fixing plate 32. A plurality of adhesive nozzles 35 are disposed on the other side of the adhesive coating base plate 31. The plurality of adhesive nozzles 35 are connected and conductive to the first adhesive coating component 33. The fiberglass cloth end of the fiberglass cloth assembly 2 cooperates with the first adhesive coating component 33 and the second adhesive coating component 34. It can be seen that the fiberglass cloth assembly 2 and the adhesive coating assembly 3 are arranged in parallel, so that the fiberglass cloth can enter the adhesive coating station of the adhesive coating assembly 3 more stably. The plurality of adhesive nozzles 35 can evenly apply adhesive to the fiberglass cloth. The fiberglass cloth is removed by an external material handling mechanism. The structure is simple and the adhesive coating effect is better.

[0020] like Figure 3 and Figure 4 As shown, in this embodiment, the first adhesive coating component 33 has a first adhesive coating groove 36 on its adhesive coating side, and a plurality of adhesive injection ports 37 are arrayed on the connecting side of the first adhesive coating component 33. A plurality of adhesive injection nozzles 35 pass through the adhesive coating base plate 31 and connect to the plurality of adhesive injection ports 37. Therefore, the plurality of adhesive injection ports 37 can fill the interior of the adhesive coating groove 36 with adhesive, resulting in more thorough contact between the fiberglass cloth and the adhesive.

[0021] like Figure 3 and Figure 5 As shown, in this embodiment, the second adhesive coating component 34 is provided with a second adhesive coating groove 38, which conforms to the shape of the first adhesive coating groove 36. The fiberglass cloth end of the fiberglass cloth assembly 2 mates with both the first adhesive coating groove 36 and the second adhesive coating groove 38. Therefore, the second adhesive coating groove 38 and the first adhesive coating groove 36 form an adhesive coating space, ensuring uniform adhesive coating on both sides of the fiberglass cloth and preventing uneven coating.

[0022] like Figure 1 and Figure 6As shown, in this embodiment, the fiberglass cloth assembly 2 includes a rotating shaft support block 21, a fiberglass cloth roll 22, and a rotating motor 23. Two sets of rotating shaft support blocks 21 are disposed on one side of the support frame 1. Both ends of the fiberglass cloth roll 22 are rotatably engaged with the two sets of rotating shaft support blocks 21, and the rotating motor 23 is rotatably engaged with one rotating end of the fiberglass cloth roll 22. Therefore, the fiberglass cloth feeding speed is controlled by the rotating motor 23, and the adhesive is evenly coated onto the fiberglass cloth through the cooperation of the rotating motor 23 and an external peristaltic pump.

[0023] like Figure 1 and Figure 3 As shown, in this embodiment, quick clips 4 are provided at both ends of the adhesive base plate 31, and several quick clips 4 cooperate with several locking buckles 5 at both ends of the fixing plate 32. Therefore, the quick clips 4 can quickly assemble or disassemble the fixing plate 32 and the adhesive base plate 31 for cleaning.

[0024] like Figure 3 As shown, in this embodiment, the fixing plate 32 is provided with an operating handle 6. Therefore, the operating handle 6 allows the fixing plate 32 to be removed after disassembly.

[0025] like Figure 3 As shown, in this embodiment, a glue recycling frame 7 is provided at the lower end of the glue-coating base plate 31, and a glue recycling head 8 is provided on one side of the glue recycling frame 7. The glue recycling head 8 is connected to an external glue recycling device. Therefore, the glue is collected through the glue recycling frame 7, and then transferred to the glue recycling device through the glue recycling head 8.

[0026] As shown in the figure, in this embodiment, the fixing plate 32 is provided with a plurality of weight-reducing grooves 9. Therefore, the plurality of weight-reducing grooves 9 can reduce the weight of the fixing plate 32, making the assembly and disassembly of the fixing plate 32 easier.

[0027] The working principle of this utility model is as follows: Before the equipment is started, the fixing plate 32 is opened, and the fiberglass on the fiberglass cloth assembly 2 is arranged on the first adhesive coating part 33. The fixing plate 32 and the adhesive base plate 31 are connected by several quick clamps 4. The end of the fiberglass cloth is connected to the external pulling device. Several glue injection nozzles 35 inject glue into the first adhesive coating tank 36 and the second adhesive coating tank 38. The fiberglass cloth is soaked in glue. The external pulling device pulls the fiberglass cloth out. The rotating motor 23 drives the fiberglass cloth roll 22 to rotate synchronously, so that the fiberglass cloth can be evenly coated with glue. Excess glue is squeezed out through the gap between the first adhesive coating tank 36 and the second adhesive coating tank 38 and is recycled and transferred through the glue recycling frame 7 and the glue recycling head 8, thereby realizing automatic and precise control of glue coating of fiberglass cloth.

[0028] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
