Embodiment 1

[0057] see figure 1 — Image 6 , a device for continuously preparing carbon nanotube films, comprising a furnace tube 1 and a collection box 2, the input end of the furnace tube 1 communicates with a carbon nanotube generating device 11, and the output end of the furnace tube 1 extends to the collection box body 2; the collection box 2 includes a box shell 21 and a box inner cavity 22 opened inside the box inner cavity 22, which is provided with an upper pre-compression roller 3, a lower pre-compression roller 4 and a receiving roller 5 , the upper pre-compression roller 3 reciprocates longitudinally, the position of the lower pre-compression roller 4 is fixed, the middle part of the upper pre-compression roller 3 and the middle part of the lower pre-compression roller 4 are arranged up and down, the middle part of the upper pre-compression roller 3, Between the middle part of the lower pre-compression roller 4, there is an inter-cylinder space 30, and the inter-cylinder spac...

Embodiment 2

[0060] Basic content is the same as embodiment 1, the difference is:

[0061] Structurally: a discharge drum 8 is arranged between the lower pre-pressing drum 4 and the receiving drum 5, and the discharge drum 8 includes a discharge roller 81 and a discharge roller 82 connected to its two ends. The heights of the roller 81 , the lower pre-pressing roller 4 , and the receiving roller 5 increase sequentially, and a plastic film 83 is wound on the discharging roller 81 .

[0062] Method: Initially, after blocking the input end of the furnace tube 1 and the inner cavity 22 of the box, first pull out the plastic film 83 wound on the discharge roller 81, and then pull it out from the bottom of the lower pre-press roller 4 Pass through, then penetrate into the gap 30 between the cylinders, subsequently, when the carbon nanotube aggregate is pre-pressed into the carbon nanotube film 9 by the upper pre-press roller 3 and the lower pre-press roller 4, the bottom of the carbon nanotube f...

Abstract

The invention discloses a device for continuously preparing carbon nanotube films. The device comprises a furnace tube and a collecting box body, wherein an input end of the furnace tube communicates with a carbon nanotube generating device, and an output end of the furnace tube extends into the collecting box body; the collecting box body comprises a box body shell and a box body inner cavity arranged in the box body; an upper pre-pressing roller, a lower pre-pressing roller and a material collecting roller are arranged in the box body inner cavity; the upper pre-pressing roller reciprocates in a longitudinal direction; a position of the lower pre-pressing roller is fixed; the middle of the upper pre-pressing roller and the middle of the lower pre-pressing roller are arranged in an up-down opposite mode; an inter-roller gap is formed between the upper pre-pressing roller and the lower pre-pressing roller, and the inter-roller gap is opposite to the output end of the furnace tube; and the inter-roller gap and the material collecting roller are respectively located at two ends of the box body inner cavity. According to design provided by the invention, the manufacturing efficiency is high, and the continuity is good.

Description

technical field [0001] The invention relates to a carbon nanotube film preparation process, belongs to the technical field of nanomaterial preparation, and in particular relates to a device and method for continuously preparing carbon nanotube films. Background technique [0002] Carbon nanotubes have excellent mechanical, electrical and thermal properties, and have important application prospects in the fields of functional compounding, energy storage and biosensing. At the same time, the assembly of carbon nanotubes into macroscopic films can be used in fields such as composite reinforcement, catalyst carrier, energy storage electrode, and heat generation, with great prospects. [0003] In the prior art, the generated carbon nanotubes are mostly gathered and wound first to obtain aggregates, and then the aggregates are rolled and flattened to obtain carbon nanotube films. Although this method can prepare carbon nanotube films, the efficiency of preparing carbon nanotube f...
