DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1:

[0027] like Figures 1 to 4As shown, the present embodiment provides a device for scraping silicone on the surface of glass fiber cloth. The two sides of the device can be matched with an unwinding machine and a winding machine for glass fiber cloth rolls to realize continuous transportation. It is a prior art and includes: a scraping tower body 1, a cooling box 2 is connected to the bottom of the scraping tower body 1, and leg frames 3 are fixedly connected to the two sides of the bottom of the cooling box 2. A feeding port 4 is connected to the upper end of the scraping tower body 1. Double-sided spraying mechanisms are provided on the inner walls of the scraping tower body 1 on both sides near the feeding port 4. Reciprocating lifting mechanisms are provided on the side walls of the scraping tower body 1 below the spraying mechanism. Both ends of the reciprocating lifting mechanism extend into the scraping tower body 1 and are fixedly connected to two symmetrically arranged electric push rods 5. The adjacent ends of the two electric push rods 5 are fixedly connected to spring rods 6. The adjacent ends of the two spring rods 6 are fixedly connected to scraping knives 7. When When performing the scraping operation, the glass fiber cloth needs to stay for a short period of time, and reciprocate scraping for more than two times to improve the processing quality. A double-sided cooling mechanism is provided in the cooling box 2. The bottom of the cooling box 2 is connected to a discharge port 8. The side walls of the opening ends of the feed port 4 and the discharge port 8 are both equipped with guide rollers 38 to guide the transportation of the glass fiber cloth roll.

The control panel 9 is electrically connected to the double-sided spraying mechanism, the reciprocating lifting mechanism, the electric push rod 5 and one end of the double-sided cooling mechanism respectively, which means that the electrical equipment of the device is electrically connected to the control panel 9. The circuit involved is a prior art, which can be fully realized by those skilled in the art. Needless to say, the device can realize the continuous scraping of silicone on both sides of the glass fiber cloth, thereby improving the production and processing efficiency and quality of the glass fiber cloth.

[0028] The double-sided spraying mechanism includes a silicone liquid tank 10, and a liquid pump 11 is fixedly connected to the upper side wall of the silicone liquid tank 10. The first end of the liquid pump 11 is connected to the silicone liquid tank 10 through a first conduit 12, and the second end of the liquid pump 11 is connected to a U-shaped tube 14 through a second conduit 13. Two control valves are provided on the U-shaped tube 14. When single-sided spraying is required, one of them can be closed. The two sides of the U-shaped tube 14 extend to both sides of the scraping tower 1. Both sides are connected to evenly arranged spray pipes 15. The spray pipe 15 is provided with a solenoid valve, which is electrically connected to the control panel 9. It can be adjusted according to the glass fiber. According to the actual width of the cloth, a proper number of spraying pipes 15 are opened to avoid wasting silicone liquid.

The second end of the reflux pump 18 is connected to a reflux pipe 20, and the reflux pipe 20 is connected to the silicone liquid tank 10. When the scraping knife 7 moves downward to scrape the silicone liquid on the surfaces of both sides of the glass fiber cloth, the scraped excess silicone liquid falls into the collecting tank 17 along the inclined surface of the scraping knife 7. At the same time, the reflux pump 18 is started to work, and the excess silicone liquid collected in the two collecting tanks 17 is refluxed to the silicone liquid tank 10 by the three-way pipe 19 for continued use. The residual material recovery is convenient and avoids material waste.

[0030] Principle of this embodiment: When the device is used to simultaneously perform scraping and coating silicone on the surfaces of both sides of the glass fiber cloth, one end of the glass fiber cloth enters the scraping and coating tower body 1 from the feed port 4. First, the double-sided spraying mechanism is started to work, and the silicone liquid can be sprayed on both sides of the glass fiber cloth at the same time. The glass fiber cloth can be continuously transported. Before the glass fiber cloth sprayed with silicone liquid moves down and is transported to the cooling box 2, the two electric push rods 5 are started to work and extend, and the scraping knife 7 is pushed to contact the silicone liquid on the surface of the glass fiber cloth. The spacing between the two scraping knives 7 is adjusted according to the thickness of the glass fiber cloth or the thickness of the silicone liquid. The processing application range is wide. Then, the reciprocating lifting mechanism is started to drive the two scraping knives 7 to synchronously reciprocate and lift, and the silicone liquid sprayed on both sides of the glass fiber cloth is scraped to ensure that the silicone liquid is coated more evenly and uniformly, and the thickness is consistent. After scraping, the glass fiber cloth is continued to be transported to the cooling box 2, and this operation is repeated. The device can realize continuous scraping and coating of silicone on both sides of the glass fiber cloth, thereby improving the production and processing efficiency and quality of the glass fiber cloth.
