Description

Technical Field

[0001] This utility model belongs to the field of carbon nanotube production technology, specifically relating to a carbon nanotube conductive slurry premixing mechanism. Background Technology

[0002] Carbon nanotube conductive paste is a functional paste made by mixing carbon nanotubes as the conductive functional phase with solvents, resin matrices, and possibly added additives. Carbon nanotubes, with their unique tubular structure and excellent electrical properties, endow the paste with good conductivity. This paste can be applied to electronic devices, energy storage, and other fields through coating, printing, and other processes. While achieving conductivity, it can also meet specific processing and usage requirements, making it a conductive material with broad application prospects.

[0003] When mixing carbon nanotube conductive slurry, carbon nanotubes, due to their large aspect ratio and high surface energy, exhibit strong van der Waals forces. Therefore, during the premixing process, carbon nanotubes are prone to attracting each other and agglomerating. To solve this problem, a suitable dispersant needs to be added to the slurry. However, in practice, the dispersant is usually added directly to the slurry. This method of addition will result in uneven dispersion of the dispersant in the slurry, which will have an adverse effect on the mixing uniformity of the slurry. Utility Model Content

However, the present application can be practiced in other ways that are not identical to those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0024] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0025] EMBODIMENT

[0026] REFERENCE Figures 1-4 For the embodiment of the present application, the embodiment provides a carbon nanotube conductive paste premixing mechanism, comprising,

[0027] The premixing mechanism 100 comprises a box body 101, a motor 102 fixedly installed on the outer side of the box body 101, a rotating rod 103 fixedly installed on the output end of the motor 102, a plurality of mixing rods 104 fixedly installed on the surface of the rotating rod 103, a feeding pipe 105 communicated with the top of the box body 101, and a discharging pipe 106 communicated with the surface of the box body 101.

[0028] The mixing mechanism 200 comprises a mixing assembly 201 for premixing the dispersant, and a timing assembly 202 for timing the dispersant.

[0029] The power provided by the motor 102 can be fully utilized through the cooperation between the mixing assembly 201 and the timing assembly 202 to complete the premixing and timing dispensing of the dispersant, solve the problem that the traditional premixing mechanism cannot premix and time dispensing the dispersant to be added, and improve the mixing uniformity of the dispersant and the slurry.

[0030] Specifically, the mixing assembly 201 includes a side box 201a fixedly installed on the top of the box body 101, a rotating shaft 201b rotatably installed on the side box 201a, a plurality of stirring rods 201c fixedly installed on the surface of the rotating shaft 201b, and a material dropping pipe 201d communicated with the bottom of the side box 201a.

[0031] Further, the mixing assembly 201 further includes a driven wheel 201e fixedly installed on the top of the rotating shaft 201b, a driving wheel 201f fixedly installed on the output end of the motor 102, and a synchronous belt 201g sleeved on the surfaces of the driven wheel 201e and the driving wheel 201f and used for transmission. The top of the side box 201a is communicated with a material injection pipe.

[0032] The driving wheel 201f, the synchronous belt 201g and the driven wheel 201e are cooperated to drive the rotating shaft 201b to rotate by the power of the motor 102, so that the rotating shaft 201b drives the stirring rods 201c to premix the dispersant in the side box 201a, and improve the mixing uniformity of the dispersant when it is put into the box body 101.

[0033] Preferably, the top of the side box 201a is fixedly installed with a mounting bearing, and the mounting bearing is sleeved on the surface of the rotating shaft 201b.

[0034] The mounting bearing is used to rotate the rotating shaft 201b, and improve the stability of the rotating shaft 201b when it rotates.

[0035] Further, the timing assembly 202 includes a driving wheel 202a fixedly installed on the surface of the output end of the motor 102, a gear 202b rotatably installed on the top of the inner cavity of the box body 101 and cooperated with the driving wheel 202a, and a hollow groove 202c opened on the surface of the gear 202b and matched with the synchronous belt 201g to dispense the dispersant.

[0036] The surface of the driving wheel 202a has two teeth, which are engaged with the gear 202b. Under the action of the motor 102, the driving wheel 202a rotates, and in turn, the teeth on the driving wheel 202a drive the gear 202b to rotate. Since there are only two teeth on the driving wheel 202a, the driving wheel 202a drives the gear 202b to rotate intermittently. When the empty slot 202c rotates to the lower side of the synchronous belt 201g, the dispersant falls from the synchronous belt 201g into the inside of the box 101, achieving the purpose of dispensing the dispersant at a fixed time and improving the uniformity of mixing of the dispersant in the inside of the box 101.

[0037] Specifically, the top of the inner cavity of the box 101 is fixedly installed with a connecting rod, and the end of the connecting rod is rotatably connected with the gear 202b through a bearing.

[0038] The connecting rod and the bearing are matched to install the gear 202b, improving the stability of the gear 202b during rotation.

[0039] Further, the bottom of the synchronous belt 201g is fixedly installed with a sealing ring, and the sealing ring is in close contact with the surface of the gear 202b.

[0040] The sealing ring is used to increase the sealing property between the synchronous belt 201g and the gear 202b, preventing the dispersant from leaking out of the gap between the synchronous belt 201g and the gear 202b, and affecting the effect of dispensing the dispersant at a fixed time.

[0041] In use, the motor 102 is used to drive the rotating rod 103 to rotate, and in turn, the rotating rod 103 drives the mixing rod 104 in the inside of the box 101 to rotate, so that the mixing rod 104 mixes and stirs the slurry in the inside of the box 101. When the motor 102 rotates, the driving wheel 201f is driven to rotate. Under the transmission action of the synchronous belt 201g, the driving wheel 201f drives the driven wheel 201e to rotate, and in turn, the driven wheel 201e drives the rotating shaft 201b to rotate, and the rotating shaft 201b drives the stirring rod 201c to rotate, so that the stirring rod 201c pre-mixes the dispersant in the inside of the side box 201a.

[0042] The motor 102 rotates and in turn drives the driving wheel 202a to rotate. When the teeth on the surface of the driving wheel 202a rotate to engage with the gear 202b, the gear 202b is driven to rotate. The driving wheel 202a drives the gear 202b once per revolution, and in turn, the gear 202b rotates intermittently. When the empty slot 202c on the gear 202b rotates to the lower side of the synchronous belt 201g, the dispersant is discharged from the inside of the side box 201a through the synchronous belt 201g and falls into the inside of the box 101 through the empty slot 202c, achieving the purpose of dispensing the dispersant at a fixed time.

[0043] In summary, through the cooperation between the mixing assembly 201 and the timing assembly 202, the power provided by the motor 102 can be fully utilized to complete the premixing of the dispersant and the timed dispensing operation, solving the problem that the traditional premixing mechanism does not have the premixing and timed dispensing functions for the dispersant to be added, and achieving the effect of improving the mixing uniformity of the dispersant and the slurry.
