Description
Technical Field
[0001] This utility model belongs to the field of glass fiber cloth technology, and specifically relates to an automatic coating equipment for glass fiber cloth. Background Technology
[0002] Fiberglass fabrics are excellent alternatives to metal materials. With the rapid development of the market economy, fiberglass fabrics have become an indispensable raw material in industries such as construction, transportation, electronics, electrical engineering, chemicals, metallurgy, environmental protection, and national defense. Due to their wide application in multiple fields, fiberglass is receiving increasing attention. As human horizons broaden and the product categories of fiberglass become more specialized, the performance requirements for fiberglass materials are also gradually increasing.
[0003] Due to imperfections in the production process, the fiberglass fabrics currently produced have aesthetic defects. The spacing between some threads does not meet production requirements, and the fabric's toughness is insufficient, breaking easily under strain. Using triethanolamine and boric acid as raw materials, aminotriethyl borate was synthesized. Using aminotriethyl borate as a precursor, it was pyrolyzed under a nitrogen atmosphere at specific temperatures. The pyrolysis products were a mixture of boron nitride and boron carbide. Boron nitride was separated by utilizing the different degrees of crystallization of aminotriethyl borate at different temperatures. The boron nitride coating significantly strengthens the fiberglass fabric.
[0004] Existing glass fiber fabric coating processes are cumbersome, requiring the separation of boron nitride solution to be applied to the glass fiber cloth, while the boron nitride solution is prone to cooling. Utility Model Content
[0005] The purpose of this invention is to provide an automatic coating device for fiberglass cloth. It has a simple structure and can pass fiberglass cloth through the bottom of the boron nitride heating chamber, and uniformly coat the surface of the fiberglass cloth with liquefied boron nitride. It has high working efficiency, strong practicality, and is suitable for widespread application.
[0006] This utility model provides the following technical solution: an automatic coating device for fiberglass cloth, including a base, a support arm fixedly provided at the rear end of the base, a heating barrel fixedly provided on the support arm, a gathering base below the heating barrel, symmetrical fixing frames fixedly provided on both sides of the base and the gathering base, guide rollers mounted on the fixing frames via rotating shafts, a coating roller provided on the support arm below the gathering base, the coating roller being connected to the support arm via a rotating shaft, and a motor for driving the rotating shaft being provided at the rear of the support arm;
[0007] The bottom of the converging base is fixedly provided with a strip frame, which is the lower opening of the heating barrel. The bottom of the strip frame is provided with an arc-shaped surface. The coating surface is surrounded by a coating surface on the side wall of the coating roller, and the coating surface is slidably connected to the strip frame.
[0008] Preferably, the lower part of the sidewall of the coating roller is lower than the upper part of the upper wall of the guide roller, and a notch is provided on one side of the arc-shaped surface. The gap formed by the notch and the coating surface matches the viscosity of the boron nitride coating liquid.
[0009] Preferably, a heating chamber is provided on the inner wall of the heating barrel, and a top cover is installed on the top of the heating barrel by threads. A motor is fixed on the top cover, and a stirring rod is connected to the output end of the motor. The stirring rod is inserted into the heating barrel, and a feeding cover is provided at the opening of the top cover by threads.
[0010] Preferably, a pressure roller is mounted above the guide roller via a bracket, and a fiberglass cloth runs through the space between the pressure roller and the guide roller.
[0011] The beneficial effects of this utility model are: simple structure, allowing glass fiber cloth to pass under the boron nitride heating chamber and uniformly coating the surface of the glass fiber cloth with liquefied boron nitride, resulting in high working efficiency and strong practicality, as detailed below:
[0012] (1) This utility model is equipped with a coating roller. When the equipment is running, the external device pulls the glass fiber cloth. The glass fiber cloth passes under the coating roller. The coating roller is driven to rotate by the motor. The boron nitride solution separated in the heating tank is discharged directly from below and adheres to the surface of the coating roller. It directly coats the glass fiber cloth passing below, thereby avoiding the process of transporting the boron nitride solution.
[0013] (2) The present invention is provided with a strip frame. When the coating roller is stationary, the coating roller is blocked at the arc surface of the strip frame. Since the boron nitride solution has viscosity, it will not overflow from the gap of the strip. When the coating roller rotates, the boron nitride solution is carried out from the gap by the coating surface, and the coating surface presses down on the glass fiber cloth, so that the boron nitride solution on the coating surface is pressed onto the glass fiber cloth, thereby completing the addition of boron nitride coating to the glass fiber cloth.

The stirring rod 13 is inserted into the heating barrel 3 to accelerate the heating efficiency. A feeding cover 11 is threadedly connected to the opening on the top cover 9.
[0024] See Figure 1-2 The base 1 is fixed with symmetrical fixing frames 5 on both sides of the convergence base 4. The fixing frames 5 are equipped with guide rollers 6 via rotating shafts. The guide rollers 6 are equipped with pressure rollers 8 via brackets. The pressure rollers 8 and guide rollers 6 are connected by fiberglass cloth 14. The fiberglass cloth 14 is connected to a pulling mechanism to tighten the fiberglass cloth 14. The support arm 2 is located below the convergence base 4 and is equipped with a coating roller 7. The coating roller 7 is connected to the support arm 2 via a rotating shaft. The support arm 2 is equipped with a motor that drives the rotating shaft to drive the coating roller 7 to rotate. The lower part of the side wall of the coating roller 7 is lower than the upper part of the guide roller 6, so that the coating roller 7 provides pressure to the fiberglass cloth 14.
[0025] See Figure 2-3 A strip frame 15 is fixedly provided at the bottom of the converging base 4. The strip frame 15 is the lower opening of the heating tank 3. The boron nitride solution separated in the heating tank 3 is discharged directly from below and adheres to the surface of the coating roller 7.

Since the boron nitride solution has viscosity, the coating surface 17 will not overflow from the strip-shaped notch 18 when it is stationary.
[0026] This utility model relates to an automatic coating device for glass fiber cloth. It has a simple structure and can pass glass fiber cloth through the bottom of the boron nitride heating chamber, and evenly coat the surface of the glass fiber cloth with liquefied boron nitride.
