[0032] To stabilize the aerogel web material 12 during flipping: guide roller support plates 1412 are respectively set perpendicular to the upper and lower flipping arm plates at the center position of the two flipping arm plates, and guide rollers 1413 are respectively set on the upper and lower guide roller support plates.

[0035] Example 2:

[0036] An aerogel winding and film wrapping method is based on the aerogel winding and film wrapping system of Example 1. The content of Example 1 is applicable to this embodiment. The winding machine 5 is set apart from the transverse cutting machine, so that after the transverse cutting machine cuts off the aerogel web, the winding roll still needs to rotate at least two turns to complete the winding of the aerogel web. Before the aerogel raw roll enters the longitudinal edge cutting machine, a length measuring sensor 19 is arranged to measure the length of the aerogel web sent out. The length measuring sensor 19 is a measuring roll sensor, which calculates the length of the aerogel web sent out by the number of revolutions of the measuring roll. The aerogel raw roll 2 sent out from the unwinding machine frame 1 is cut to a certain width by the longitudinal edge cutting machine 3, and then sent to the winding roll 13 of the winding station 501 of the winding machine 5. When the measured length reaches the designed winding length, the transverse cutting machine 4 is started to cut off the aerogel web. After receiving the cutting of the aerogel web by the transverse cutting machine, the main shaft drive reducer is started to exchange and turn over the winding station 501 and the winding completion station 502. The PE film is manually unwound from the PE film roll, and the PE film is wrapped around the roll surface with the aerogel web being wound. The PE film is cut by hand after at least two layers of PE film are wrapped around the aerogel web roll, and then the aerogel winding and film wrapping are completed by using adhesive tape.

[0037] In order to operate accurately and conveniently: the PE film is manually unwound from the PE film roll when the winding roll of the winding station is lifted to a rotation angle of 30 to 60 degrees.

[0038] Figure 9 As shown, the winding station 501 is turned over to approach the winding completion station 502 for continuous winding, and it can be seen that the PE film 1410-1 has been wound into the aerogel roll at this time; Figure 10 As shown, after the winding station 501 is turned over to approach the winding completion station 502 for continuous winding, the PE film 1410-1 is continuously wrapped, and the aerogel auxiliary material is wound into the winding roll of the winding station.

[0039] The aerogel winding and packaging film system and the winding and packaging film method change the traditional manual carrying mode, greatly reduce the labor intensity, and improve the production efficiency.

After the aerogel web material is cut by the transverse cutting machine, the main shaft drive reducer is started to start the winding station and the winding completion station are interchanged and flipped. The PE film is manually pulled out from the PE film roll and attached to the surface of the roll material. As the aerogel web material is being wound up, the winding continues until the winding completion station. After the PE film has wrapped the aerogel web material shaft with at least 2 layers, the PE film is manually cut and then the aerogel winding and wrapping is completed with tape.

7. The method according to claim 6, characterized in that, The manual extraction of PE film from the PE film roll is performed when the winding roller at the winding station is raised to between 30 and 60 degrees.

8. The method according to claim 6, characterized in that, The length measuring sensor is a measuring roller sensor.
