[0024] See also Figure 1 to Figure 2 , the embodiment of the utility model provides an extrusion-type glue dipping device for processing aerogel felt, and the extrusion-type glue dipping device for processing aerogel felt includes a tank body;

[0025] The upper end of the tank body is fixed with an upper cover body 8 through a flange 7, and an air filling conduit connection port 10 is fixed on the upper cover body 8, and a feeding port 9 for injecting sol is also provided;

[0026] A reel 1 with fiber felt 2 wound around it is also placed inside the tank body. The wound fiber felt 2 is in a spiral shape, and multiple sheet pressure bags 3 and porous flexible interlayers 4 are placed between adjacent fiber felts 2. One or more inflation ports are left on the side of any sheet pressure bag 3.

[0027] It should be noted that: in this device, when the fiber felt 2 is dipped in glue, it is firstly wound on the reel 1 in a spiral shape, and in the process of winding the fiber felt 2, a sheet pressure bag 3 is continuously placed inside it. The sheet pressure bag 3 itself is an air bag, and gas can be injected into it to make it expand. After expansion, the fiber felt 2 can be squeezed, and the air inside the fiber felt 2 is expelled by squeezing, so that it can have a better absorption effect when absorbing the sol later.

[0028] In the embodiments of the present invention, please refer to Figure 1 to Figure 2 The upper cover 8 is also provided with a thermometer 11 and a barometer 12 extending into the interior of the tank, and a transparent observation window 13 is also provided on the upper cover 8;

[0030] It should be noted that the thermometer 11 and the barometer 12 are arranged on the tank body to monitor the temperature and pressure inside the tank body, ensuring that the internal conditions are the most suitable state for the fiber felt 2 to absorb the sol, thereby improving the processing efficiency and the quality of the finished rubber felt;

[0031] It is also necessary to explain that through the provided jacket 14 and the opening, a heating or cooling medium can be injected into the interior to adjust the temperature of the tank body.

[0032] In the embodiments of the present invention, please refer to Figure 1 An air filling nozzle 5 is fixed to one end of the reel 1, one end of the air filling nozzle 5 is connected to an air distribution pipe 6, and the other end of the air distribution pipe 6 is connected to the air filling port on the side of the sheet-shaped pressure bag 3;

[0033] The other end of the inflation pipe opening 5 is connected to the inflation conduit connection opening 10 .

[0034] It should be noted that one end of the inflation pipe port 5 is connected to the inflation duct connection port 10, and the other end is connected to the sheet-like pressure bag 3 through the gas distribution pipe 6, so it is more convenient to inject gas into the sheet-like pressure bag 3, which is more practical.

[0035] In the embodiments of the present invention, please refer to Figure 1 The porous flexible interlayer 4 is oil-resistant synthetic rubber with a heat resistance of not less than 150°C. The size of the porous flexible interlayer 4 in the width direction is greater than or equal to the width of the fiber felt 2, and the length direction is also greater than or equal to the length of the fiber felt 2. The thickness of the porous flexible interlayer 4 can be compressed by 10-90% under a pressure of 1-15MPa;

[0036] The sheet-shaped pressure bag 3 is made of oil-resistant elastic rubber, and the length of the sheet-shaped pressure bag 3 is the length of the fiber felt 2 , and the width is the width of the fiber felt 2 .

[0037] It should be noted that this arrangement can maximize the contact area between the sheet-like pressure bag 3 and the fiber felt 2 and between the porous flexible interlayer 4 and the fiber felt 2, which can provide better protection on the one hand and ensure a more comprehensive range of action on the other.
