Abstract

The invention provides a collection device for a sponge-state carbon nanotube. The collection device comprises a tube furnace and a collection box which is communicated with the tube furnace, wherein the tube furnace is applied to catalytic generation of a carbon nanotube film; a spinning shaft and a collecting device arranged on the spinning shaft are arranged inside the collection box; the spinning shaft can be driven to rotate, so that the carbon nanotube film catalytically generated by the tube furnace is wound on the collection device; a laminating device matched with the spinning shaft is also arranged inside the collection box; and the distance between the laminating device and the spinning shaft is adjustable. Compared with the prior art, batch collection of the large-area adjustable sponge state carbon nanotube can be realized by the collection device for the sponge state carbon nanotube disclosed by the invention, and the collection device is simple in structure, stable, reliable, high in collection efficiency, and applicable to large-scale industrial production.
