Description

Technical Field

[0001] This utility model relates to the technical field of masterbatch preparation device, specifically a carbon nanotube masterbatch premixing treatment device. Background Technology

[0002] Carbon nanotube conductive masterbatches can be applied in fields such as electronics, medical devices, aerospace, and energy storage. In the electronics field, carbon nanotube conductive masterbatches can be used to manufacture high-performance thin-film batteries, displays, and transistors. In the medical device field, carbon nanotube conductive masterbatches can be used to manufacture medical sensors, wearable devices, and artificial organs. In the aerospace field, carbon nanotube conductive masterbatches can be used to manufacture conductive coatings, conductive failure detection, and spacecraft batteries. The preparation of carbon nanotube conductive masterbatches usually requires the premixing of carbon nanotubes with a resin matrix, which necessitates the use of a masterbatch premixing treatment device.

[0003] Currently, traditional masterbatch premixing devices still have some shortcomings. Most of these devices are semi-open feeding premixing devices. When carbon nanotubes and PC resin are heated and stirred, the small particle size and light weight of carbon nanotubes make it easy to generate a lot of dust during the mixing process, thus polluting the production environment. At the same time, since the carbon nanotubes and PC resin are not pre-compressed during feeding, there are gaps between the two materials, which easily lead to stratification during stirring, resulting in poor mixing effect of carbon nanotubes and PC resin in subsequent stirring. To address these issues, we propose a carbon nanotube masterbatch premixing device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figures 1-5 In this embodiment of the present invention, a carbon nanotube masterbatch premixing treatment device includes: a container cylinder 1, a support plate connected to the outer surface of the container cylinder 1, a pressing mechanism 2 and a stirring mechanism 3 arranged inside the container cylinder 1, the pressing mechanism 2 extending to the outside of the container cylinder 1 and connected to the support plate, a transmission component 4 arranged on the pressing mechanism 2, the transmission component 4 extending to the inside of the container cylinder 1 and engaging with the stirring mechanism 3, a discharge pipe 5 connected to the bottom of the container cylinder 1, a cooling mechanism 6 arranged on the outer surface of the discharge pipe 5, and a cutting component 7 arranged on the cooling mechanism 6.

[0025] Specifically, by activating the pressing mechanism 2, the mixture can be extruded while the transmission component 4 drives the stirring mechanism 3 to rotate, thereby allowing the stirring mechanism 3 to stir the extruded mixture, so that the PC resin and carbon nanotubes can be better mixed, improving the mixing effect. By opening the cooling mechanism 6, the mixed material can be discharged. Activating the cutting component 7 can rotate to cut the discharged paste-like mixture into granules. Finally, activating the cooling mechanism 6 blows out cold air, placing the cold air on the surface of the masterbatch to cool the masterbatch, thereby accelerating the cooling speed of the masterbatch and increasing the molding rate of the masterbatch.

[0026] Example 2:

[0027] Please see Figures 2-4In this embodiment of the present invention, a carbon nanotube masterbatch premixing treatment device includes a pressing mechanism 2 comprising two crossbars 201, two pressure rollers 202, two linkage gears 203, and a motor 204. The two crossbars 201 are rotatably connected inside a container cylinder 1, with one end of each crossbar extending to the outside of the container cylinder 1. The two pressure rollers 202 are respectively fixedly connected to the outer surfaces of the two crossbars 201. The two linkage gears 203 are respectively connected to one end of the two crossbars 201 and mesh with each other. The motor 204 is connected to the top of a support plate, and one end of the motor 204's output shaft extends into the container cylinder 1 and connects to one end of one of the crossbars 201. The stirring mechanism 3 includes two crossbeams 301, a housing 302, a stirring rod 303, and a first bevel gear 304. The opposite ends of the two crossbeams 301 are connected to the inner surface of the container cylinder 1. The connection includes a housing 302 connected between adjacent ends of two crossbeams 301, a stirring rod 303 rotatably connected to the bottom of the housing 302 with its top end extending into the interior of the housing 302, a first bevel gear 304 connected to the top end of the stirring rod 303, and a transmission assembly 4 including a connecting rod 401, a second bevel gear 402, two transmission rollers 403, and a transmission belt 404. The connecting rod 401 is rotatably connected between the inner wall of the container cylinder 1 and one side of the inner wall of the housing 302, with one end of the connecting rod 401 extending into the outside of the container cylinder 1. The second bevel gear 402 is connected to the outer surface of the connecting rod 401 and meshes with the first bevel gear 304. The two transmission rollers 403 are respectively connected to the outer surface of one end of the output shaft of the connecting rod 401 and one end of the connecting rod 401. The transmission belt 404 is connected between the outer surfaces of the two transmission rollers 403.

[0028] Specifically, the output shaft of the starter motor 204 drives one of the linkage gears 203 to rotate via one of the crossbars 201. One of the linkage gears 203 drives another linkage gear 203 to rotate, causing the other crossbar 201 to rotate. This causes the two pressure rollers 202 to rotate in opposite directions, squeezing the PC resin and carbon nanotubes that have fallen between the two pressure rollers 202. The squeezed material falls into the container cylinder 1. At this time, the output shaft of the motor 204 drives one of the transmission rollers 403 to rotate. One of the transmission rollers 403 drives another transmission roller 403 to rotate via a transmission belt 404. The other transmission roller 403 drives the second bevel gear 402 to rotate via a connecting rod 401. The second bevel gear 402 drives the first bevel gear 304 to rotate, which in turn drives the stirring rod 303 to rotate. Through the heating of multiple heating rods, the squeezed PC resin and carbon nanotubes inside the container cylinder 1 are softened. The rotation of the stirring rod 303 continuously stirs the softened PC resin and carbon nanotubes, allowing them to mix better and improving the mixing effect.

[0029] Example 3:

[0030] Please see Figures 1-5 In this embodiment of the present invention, a carbon nanotube masterbatch premixing treatment device includes a cooling mechanism 6 comprising a baffle 601, a cold air chamber 602, a refrigeration device 603, a blower 604, a connecting pipe 605, an exhaust pipe 606, and multiple exhaust holes 607. The baffle 601 is connected to the outer surface of the discharge pipe 5, the cold air chamber 602 is connected to the top of the baffle 601, the refrigeration device 603 is fixedly installed inside the cold air chamber 602, and the blower 604 is connected to the front of the cold air chamber 602, with the output end of the blower 604 extending into the cold air chamber. Inside 602, a connecting pipe 605 is connected to one side of the cold air box 602, and one end of the connecting pipe 605 passes through the baffle 601 and extends into the interior of the baffle 601. An exhaust pipe 606 is connected to one end of the connecting pipe 605. Multiple exhaust holes 607 are equally spaced on the outer surface of the exhaust pipe 606. A cavity is opened inside the container cylinder 1. Multiple heating rods are installed in a ring at equal intervals inside the cavity. A feed hopper is connected to the top of the container cylinder 1, and a support base 8 is connected to the bottom of the container cylinder 1. A receiving tray 9 is installed on the support base 8.

[0031] Specifically, by opening the discharge valve on the discharge pipe 5, the mixture inside the container cylinder 1 can be discharged into the baffle 601. The cutting assembly 7, blower 604, and refrigeration device 603 are started. The blower 604 blows air into the cold air box 602. The refrigeration device 603 generates cold air inside the cold air box 602. After the air comes into contact with the cold air, it is cooled down. The cold air is then transported to the interior of the air outlet pipe 606 through the connecting pipe 605. It is blown into the lower part of the discharge pipe 5 through multiple exhaust holes 607 to cool the masterbatch falling on the top of the receiving tray 9, so that the masterbatch solidifies quickly, thereby improving the masterbatch forming rate. The support base 8 can improve the stability of the device placement.

[0032] The working principle of this utility model is as follows: First, the operator opens the hopper cover and puts PC resin and carbon nanotubes into the container cylinder 1 through the hopper. Then, the hopper cover is closed to seal the inside of the container cylinder 1. At this time, the motor 204 is started. The output shaft of the motor 204 drives one of the linkage gears 203 to rotate through one of the crossbars 201. When one linkage gear 203 rotates, it drives another linkage gear 203 to rotate, which in turn drives another crossbar 201 to rotate, thereby causing the two pressure rollers 202 to rotate in opposite directions. This squeezes the PC resin and carbon nanotubes that fall between the two pressure rollers 202. The squeezed material falls into the container cylinder 1. At the same time, the output shaft of the motor 204 drives one of the transmission rollers 403 to rotate. One transmission roller 403 drives another transmission roller 403 to rotate through the transmission belt 404. The other transmission roller 403 drives the second bevel gear 402 to rotate through the connecting rod 401. This causes the second bevel gear 402 to drive the first bevel gear 304 to rotate, which in turn drives the stirring rod 303 to rotate. Then, the mixture is heated by multiple heating rods. The extruded PC resin and carbon nanotubes inside container cylinder 1 are softened. During this process, the rotating stirring rod 303 continuously agitates the extruded and softened PC resin and carbon nanotubes, allowing for better mixing and improving the mixing effect. After mixing is complete, the discharge valve on the discharge pipe 5 is opened to guide the mixture inside container cylinder 1 into baffle 601. Then, the cutting assembly 7, blower 604, and cooling device 603 can be activated. The output of blower 604 blows air into the cold air chamber 602. At this time, the refrigeration device 603 will generate cold air inside the cold air box 602. The cold air is transported to the inside of the air outlet pipe 606 through the connecting pipe 605 and finally blown out through multiple exhaust holes 607. The cold air is constantly blowing on the lower part of the discharge pipe 5. At this time, the cutting component 7 cuts the mixture discharged from the inside of the discharge pipe 5, thereby cutting the mixture into granules. The granules of the mixture will fall on the top of the receiving tray 9. At this time, the cold air is constantly blowing towards the top of the receiving tray 9 to cool the masterbatch with air, so that the masterbatch solidifies quickly, thereby improving the masterbatch forming rate.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
