Description

Technical Field

[0001] The present invention relates to the technical field of preparation of carbon nanotube macroscopic materials, and in particular to a device for collecting carbon nanotube macroscopic materials. Background Art

[0002] Carbon nanotube macroscopic materials (including fibers and films) have become strategic materials in the fields of aerospace, flexible electronics and smart materials due to their unique electrical conductivity, mechanical strength and lightweight advantages. In the preparation process, solution immersion is a key post-processing process, which drives the structural densification and ordered reconstruction of three-dimensional carbon nanotube aerogels through the physical-chemical synergy of the liquid medium. Specifically, the three-dimensional network aerogel generated by the chemical vapor deposition (CVD) method has ultra-high porosity and loose entanglement characteristics. Through the directional impregnation treatment of specific solvents, the capillary contraction effect induced by surface tension can be used to cause the carbon nanotube bundles to be arranged axially and form a dense stacking structure. This process not only significantly improves the density of the macroscopic material, but also can achieve precise design of fiber diameter and film size by controlling the solvent ratio, thereby giving the material continuous mesoscopic order and multifunctional properties.

[0003] However, the industrial production of carbon nanotube macroscopic materials still faces the following core challenges. During the solution immersion process, the coupling effect of the solvent evaporation rate gradient and the solute concentration gradient causes the fiber cross section to show a stratified alienation of "dense cortex-porous core", while the film produces edge warping and thickness fluctuations due to asymmetric shrinkage in the width direction, which seriously restricts its performance consistency. Traditional exogenous heating drying methods are prone to solvent residue and stress concentration. Microcracks are formed inside the fiber due to the evaporation of residual solvent, and the film is more prone to interlayer delamination during drying due to its larger specific surface area, resulting in a decrease in interfacial bonding strength. At the same time, existing intermittent collection devices (such as drum / roller pressing systems) are difficult to adapt to the differentiated deformation of fibers and films, affecting processing quality. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a collection device for carbon nanotube macroscopic materials in view of the deficiencies in the prior art.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: A collection device for carbon nanotube macroscopic materials, comprising: a contraction module, a base frame, a plurality of brass electrified driving wheels, a plurality of brass electrified driven wheels, an insulating frame, a displacement mechanism, a stepping motor, a collection servo motor, a collection rod, a winding magnetic powder clutch, a laser rangefinder, a tension sensor and a controller, wherein the contraction module is connected to the plurality of brass electrified driven wheels, the insulating frame, the displacement mechanism, the laser rangefinder and the tension sensor are all installed on the base frame, and the plurality of brass electrified driving wheels are connected to the winding magnetic powder clutch, the insulating frame, the displacement mechanism, the laser rangefinder and the tension sensor are all installed on the base frame, and the plurality of brass electrified driven wheels are connected to the winding magnetic powder clutch, the insulating frame, the displacement mechanism, the laser rangefinder and the tension sensor are all ...

[0006] The beneficial effects of the technical solution of the present invention are as follows: after the carbon nanotube macroscopic material enters the drying module, it passes around the brass electrified driven wheel and then passes around the brass electrified driving wheel. Due to the excellent thermal conversion characteristics of the carbon nanotube macroscopic material, the electrical energy is converted into thermal energy under the action of the positive pole of the power supply carried by the brass electrified driving wheel and the negative pole of the power supply carried by the brass electrified driven wheel, thereby evaporating the residual solution on the carbon nanotube macroscopic material. The displacement mechanism drives the collection servo motor and other parts to move forward and backward, so that the collection rod can collect evenly. During operation, the collection servo motor drives the collection rod to rotate and collect the carbon nanotube macroscopic material. This solves the problems of poor uniformity, low drying efficiency, and inability to collect continuously in the existing collection method. Automatic collection of nanotube fibers and carbon nanotube films is achieved.

[0007] Furthermore, when collecting carbon nanotube film, the shrinking module process is connected to a unwinding shaft, the unwinding shaft is connected to an unwinding magnetic powder clutch, the unwinding magnetic powder clutch is connected to an unwinding servo motor, the unwinding magnetic powder clutch and the unwinding servo motor are both connected to the controller, and the unwinding shaft process is connected to carbon nanotube aerogel production equipment.

[0008] The beneficial effect of adopting this further technical solution is that the carbon nanotube film collection process, compared to the carbon nanotube fiber collection process, includes an additional step: the carbon nanotube aerogel, after being produced from the furnace mouth, adheres to a conductive substrate unwound by the unwinding servo motor in the unwinding module, which is connected to the unwinding magnetic powder clutch and drives the unwinding shaft. The unwinding magnetic powder clutch then enters the retraction module. This facilitates the coordination of the rewinding magnetic powder clutch and the unwinding magnetic powder clutch when collecting carbon nanotube macrofilms, ensuring consistent torque during the collection process, and thus expanding the scope of application.

[0012] The beneficial effect of the above-mentioned further technical solution is that the carbon nanotube aerogel is guided into the solution tank by active guide wheels. Once in the solution tank, the carbon nanotube aerogel rapidly shrinks under the action of the solution to form carbon nanotube fibers. The carbon nanotube fibers are then drawn out of the solution through the guide wheel assembly and out of the shrinkage module. A water filter brush is installed in the middle of the guide wheel assembly. The solution extracted from the liquid by the carbon nanotube fibers is filtered out by the water filter brush and falls into the water guide trough and returns to the solution tank.

[0015] Furthermore, the plurality of brass electrified driving wheels are slidably mounted on the insulating frame, and the plurality of brass electrified driving wheels are all connected to a synchronous belt transmission module, and the synchronous belt transmission module is connected to the stepping motor.

[0016] The beneficial effect of adopting this further technical solution is that, because different voltages affect the drying effect of macroscopic materials, the spacing between the brass live driving wheel and the brass live driven wheel can be adjusted by sliding to adjust the voltage, thereby optimizing the drying effect. The configuration of the synchronous belt drive module enables a single stepper motor to drive multiple brass live driving wheels to rotate synchronously, simplifying the structure and reducing costs.

The displacement motor drives the support plate on the movable end of the displacement screw to move forward and backward. The displacement motor drives the collection servo motor and other components to move forward and backward, and the travel range is controlled by the travel switch.

[0023] Furthermore, a guide wheel is installed on one side of the base frame adjacent to the shrinkage module.

[0024] The beneficial effect of adopting the above further technical solution is that the guide wheel is located in front of the drying module to guide the fibers parallel to the entrance of the drying module, so that the carbon nanotube macro-material can be easily led out of the shrinking module and then redirected by the guide wheel before entering the drying module.

The unwinding magnetic powder clutch then enters the retraction module. This facilitates the coordination of the rewinding magnetic powder clutch and the unwinding magnetic powder clutch when collecting carbon nanotube macrofilms, ensuring consistent torque during the collection process, and thus expanding the scope of application.

[0042] Furthermore, when collecting carbon nanotube fibers, the shrinking module 2 is connected to a carbon nanotube aerogel production device.

[0045] The beneficial effect of the above-mentioned further technical solution is that the carbon nanotube aerogel is guided into the solution tank by active guide wheels. Once in the solution tank, the carbon nanotube aerogel rapidly shrinks under the action of the solution to form carbon nanotube fibers. The carbon nanotube fibers are then drawn out of the solution through the guide wheel assembly and out of the shrinkage module. A water filter brush is installed in the middle of the guide wheel assembly. The solution extracted from the liquid by the carbon nanotube fibers is filtered out by the water filter brush and falls into the water guide trough and returns to the solution tank.

[0046] like Figures 1 to 4 As shown, further, a lifting platform 13 is connected to the bottom of the shrinking frame 8, and the guide wheel group 11 is composed of a plurality of guide wheels. The plurality of guide wheels of the guide wheel group 11 are arranged in a gradually shrinking space from the top to the bottom of the solution tank 10, and the surfaces of the guide wheel group 11 are coated with ceramic material.

[0047] The beneficial effect of adopting the above further technical solution is that the height of the shrinking module can be adjusted by the lifting platform, so that the height of the shrinking module is adapted to the height of the shrinking module, thereby improving uniformity.

[0048] Among them, the guide wheel group 11 can be composed of multiple guide wheels, and the multiple guide wheels are arranged in sequence from the top to the bottom of the solution tank 10. The multiple guide wheels are located on the same plane, and the lengths of the multiple guide wheels can be reduced in sequence from the top to the bottom of the solution tank 10.

[0050] The beneficial effect of adopting this further technical solution is that, because different voltages affect the drying effect of macroscopic materials, the spacing between the brass live driving wheel and the brass live driven wheel can be adjusted by sliding to adjust the voltage, thereby optimizing the drying effect. The configuration of the synchronous belt drive module enables a single stepper motor to drive multiple brass live driving wheels to rotate synchronously, simplifying the structure and reducing costs.

[0057] like Figures 1 to 4 As shown, further, a guide wheel 16 is installed on one side of the base frame 15 adjacent to the shrink module 2.

[0058] The beneficial effect of adopting the above further technical solution is that the guide wheel is located in front of the drying module to guide the fibers parallel to the entrance of the drying module, so that the carbon nanotube macro-material can be easily led out of the shrinking module and then redirected by the guide wheel before entering the drying module.

[0059] like Figures 1 to 4 As shown, an embodiment of the present invention provides a carbon nanotube macroscopic material collection device, comprising an unwinding module 1, a retraction module 2, a drying module 3, a collection module 4, an unwinding shaft 5, an unwinding magnetic powder clutch 6, an unwinding servo motor 7, a retraction frame 8, an active guide wheel 9, a solution tank 10, a guide wheel assembly 11, a water filter brush 12, a lifting platform 13, a water guide trough 14, a base frame 15, a guide wheel 16, a brass electrified active wheel 17, a brass electrified driven wheel 18, a manual lifting device 19, a polyethylene frame 20, a polyethylene lifting platform 21, a conductive bearing 22, a brass shaft 23, a synchronous belt drive module 24, a stepping motor 25, a collection servo motor 26, a shift motor 27, a shift screw 28, a collection rod 29, a rewinding magnetic powder clutch 30, a laser rangefinder 31, a tension sensor 32, a travel switch 33, and a support plate 34. The device features energy saving and high efficiency, and can achieve constant torque and constant linear speed collection.

[0060] Carbon nanotube fiber collection process: During operation, carbon nanotube aerogel is produced from the furnace mouth and then enters the shrinking module 2. At this time, the carbon nanotube aerogel is guided by the active guide wheel 9 to the solution tank 10. At the same time, the height of the shrinking module 2 can be adjusted by the lifting platform 13. After entering the solution tank 10, the carbon nanotube aerogel rapidly shrinks under the action of the solution to form carbon nanotube fibers. The carbon nanotube fibers are then guided out of the solution through the guide wheel assembly 11 and out of the shrinking module 2. A water filter brush 12 is installed in the middle of the guide wheel assembly 11. The solution brought out of the liquid by the carbon nanotube fibers is filtered out by the water filter brush 12 and falls into the water guide trough 14 and returns to the solution tank 10.

[0061] Compared with the carbon nanotube fiber collection process, the carbon nanotube film collection process has an additional step, that is, after the carbon nanotube aerogel is produced from the furnace mouth, it adheres to the conductive substrate released by the unwinding servo motor 7 in the unwinding module 1 connected to the unwinding magnetic powder clutch 6 and drives the unwinding shaft 5 to release it, and then enters the shrinking module 2 together with the substrate (conductive substrate).

[0062] After exiting the shrinking module 2, the macroscopic carbon nanotube material passes through the guide wheel 16 and changes direction before entering the drying module 3. Once in the drying module 3, the macroscopic carbon nanotube material passes around the brass electrified driven wheel 18 and then around the brass electrified driving wheel 17. Due to the excellent thermal conversion properties of the macroscopic carbon nanotube material, the positive power supply from the brass electrified driving wheel 17 and the negative power supply from the brass electrified driven wheel 18 convert electrical energy into thermal energy, thereby evaporating any residual solution from the macroscopic carbon nanotube material. Because different voltages can affect the drying effect of the macroscopic material, the distance between the brass electrified driving wheel 17 and the brass electrified driven wheel 18 can be adjusted using a manual lifting device 19. After multiple drying steps, the macroscopic carbon nanotube material is then exited.

[0063] After being guided out of the drying module 3, the carbon nanotube macroscopic material passes through the tension sensor 32 and enters the collection module 4. The carbon nanotube macroscopic material is wound on a winding shaft mounted on the collection rod 29. The shift motor 27 drives the support plate 34 on the movable end of the shift screw 28 to move back and forth. The collection servo motor 26 and the winding magnetic powder clutch 30 are mounted on the support plate 34. The output shaft of the collection servo motor 26 drives the input shaft of the winding magnetic powder clutch 30, and the output end of the winding magnetic powder clutch 30 is connected to the collection rod 29. During operation, the collection servo motor 26 drives the collection rod 29 to rotate and collect the carbon nanotube macroscopic material. At the same time, the shift motor 27 drives the collection servo motor 26 and other parts to move forward and backward, and the range of movement is controlled by the travel switch 33. This allows the collection rod 29 to collect evenly.

[0064] When collecting carbon nanotube fibers, the winding magnetic powder clutch 30 adjusts torque output based on data from the tension sensor 32 to ensure consistent torque throughout the collection process. Simultaneously, a laser rangefinder 31 located behind the collection module 4 measures the thickness of the collected carbon nanotube material in real time. As the collected length increases, the diameter of the winding spool increases. Upon receiving thickness data from the laser rangefinder 31, the control system controls the collection servo motor 26 to reduce its angular velocity accordingly, enabling the collection module 4 to maintain a constant linear velocity.

[0065] When collecting the carbon nanotube film, the winding magnetic powder clutch 30 cooperates with the unwinding magnetic powder clutch 6 to ensure that the torque is consistent during the collection process.
