[0002] An aerogel refers to a nano-porous solid material formed by replacing the liquid phase in a gel with a gas through a sol-gel method and using a certain drying method. An aerogel composite coil is prepared by reinforcing the matrix with composite fibers, so that the aerogel has certain flexibility and toughness, and the application field of the aerogel material is broadened.

[0029] Referring to Figure 2 And Figure 3 , the product shaft A 102 is installed on the pay-off reel 101, and the first motor 103 and the clutch 104 are started to drive the product to unwind at a constant speed; when the product is transported to the front end of the pressing and transporting assembly, the upper sliding block 402 in the pressing devices 4 (referring to Figure 6 ) on the left and right sides is driven by the multi-stroke cylinder 401 to press down the driven pressing shaft 109, which cooperates with the driving pressing shaft 110 to press the product; after pressing, the second motor 106 drives the driving pressing shaft 110 to transport the product backward; the pressing devices 4 at the front and rear ends are connected by a belt 111 to transmit a certain amount of power and prevent the middle of the product from sagging, which is inconvenient for detection; during the transportation process, the product passes through the dust removal and water spraying devices in sequence, and finally the product is transferred to the rotating platform

[0030] The dust removal device is located at the front-end pressing device 4 (referring to Figure 6)At the rear, the upper blower 113 is installed on the blower mounting bracket 112.
