As shown in fig. 3 and 4, the glue applying mechanism 300 of the embodiment of the present application includes a cylindrical glue applying roller 310 and a glue blocking mechanism 320 disposed at the glue applying roller 310. The aerogel blanket conveyed by the first feeding mechanism 100 passes under the gluing roller 310.
The inner surface of the glue blocking mechanism 320 and the cylindrical surface of the gluing roller 310 together form a glue containing groove 330, and glue is contained in the glue containing groove 330. The glue receiving slot 330 is located above the aerogel blanket.
The glue receiving groove 330 is located at the right side of the gluing roller 310, and the cylindrical surface of the gluing roller 310 is glued when the gluing roller 310 rolls, and the aerogel blanket is glued when passing under the gluing roller 310.

The gluing mechanism 300 has the advantages that glue is not easy to waste; however, this arrangement causes problems: when the cylindrical surface of the glue applicator roller 310 sticks and moves upward and brings glue to the overlying aerogel blanket in the lower glue receiving trough 330, the glue will flow downward due to the gravity of the glue application, resulting in too little glue being applied to the final aerogel blanket. The surface of the aerogel felt is made of rough and uneven glass fiber yarns, and when the aerogel felt is attached to cloth, the aerogel felt is not firmly attached, so that the aerogel felt is easy to separate.
In contrast to the glue mechanism 300 of fig. 5, the glue mechanism 300 of fig. 3 of the present application allows a sufficient amount of glue to be applied to the aerogel blanket so that the aerogel blanket fits snugly against the fabric. Thus, the glue mechanism 300 shown in FIG. 3 herein is the preferred glue mechanism 300. Only the details of the glue applying mechanism 300 shown in fig. 3 will be described below.
As an improvement, the glue applying mechanism 300 shown in fig. 3 of the present application has a small gap X (not shown) between the edge of the glue blocking mechanism 320 and the cylindrical surface of the glue applying roller 310, and the gap X makes glue adhere to the surface of the glue applying roller 310 more easily. The gap X is 0.05 mm-1 mm. As a more preferred option, the size of the gap X can be adjusted because the amount of glue required on the surface of the aerogel blanket is different when different aerogel blankets are being patched.
In the glue applying mechanism 300 shown in fig. 3 of the present application, the glue blocking mechanism 320 includes a blocking plate 321 and two side plates (not shown) located at the end of the blocking plate 321, as shown in fig. 4. The baffle 321, the side plates, and the cylindrical surface of the glue roller 310 together form a glue receiving slot 330.
As an improvement, the glue blocking mechanism 320 further includes a flexible sheet 322 at the blocking plate 321. Wherein, one side of the flexible sheet 322 is connected with the baffle 321; the other side of the flexible sheet 322 is adjacent to the cylindrical surface of the glue roller 310.
As an improvement, in the glue applying mechanism 300 shown in fig. 3 of the present application, a glue container 340 is disposed below the glue receiving slot 330 and the glue applying roller 310. To prevent glue from leaking out of the top.
As an improvement, a glue inlet 350 is arranged above the glue containing groove 330. Firstly, the other side of the flexible sheet 322 is abutted against the cylindrical surface of the gluing roller 310, and then glue is injected into the glue accommodating groove 330 from the glue inlet 350; when the glue application is started, the glue application roller 310 starts to rotate, and the position of the baffle 321 and the flexible sheet 322 can be adjusted as required to keep the gap X at a proper size.
The cloth 700 of this application is temperature resistant cloth layer, can be high temperature resistant asbestos cloth, glass fiber cloth, or high silica fiber cloth. Preferably, the temperature-resistant fabric layer of the present invention is a glass fabric (glass fabric).
Aerogel blanket 600 of the present specific embodiment includes: a needled felt of filamentary structures, and aerogel particles dispersed within the needled felt.
The fiber can be aluminum silicate fiber, PET blend fiber, polyacrylonitrile fiber, glass fiber, high silica fiber, or carbon fiber. Preferably, however, the fibers of the aerogel blanket are glass fibers.
Aerogel particles, most commonly formed from alumina or silica. The aerogel particles are based on nano-silica aerogel, since silica aerogel has properties that make it a good choice for thermal insulation.
