DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In one embodiment, reference Figure 1-Figure 9 , a high-efficiency graphene heat-conducting plastic mixing device, comprising a heat-insulating barrel 1, and a granulating mechanism 2 fixed directly below the heat-insulating barrel 1, a feeding assembly 3 is fixedly connected to the top of the heat-insulating barrel 1, and the feeding assembly 3 is used to put materials, and also comprises: a mixing mechanism 4, which is arranged inside the heat-insulating barrel 1, and the mixing mechanism 4 is connected to the end of the feeding assembly 3; wherein the mixing mechanism 4 comprises a mixing barrel 1 41 and a mixing barrel 2 42, the mixing barrel 2 42 is fixed inside the mixing barrel 1 41, and the mixing barrel 2 42 is fixed at A plurality of filter holes 43 are provided at the bottom of the mixing barrel 41 and the mixing barrel 2, and a gap baffle 44 is provided directly below the filter holes 43; a driving mechanism 5 is installed on the heat-insulating barrel 1 and fixedly connected to the middle of the gap baffle 44, so as to drive the gap baffle 44 to rotate; a discharge pipe 45 is connected to the bottom of the mixing barrel 41, and one end of the discharge pipe 45 passes through the heat-insulating barrel 1 and the granulating mechanism 2 respectively; a spiral blade 46 is fitted inside the discharge pipe 45, and the spiral blade 46 is fixed to the surface of the driving shaft 51.

[0035] By adopting such a scheme, the graphene and plastic raw materials can be dispersed and mixed for multiple times during the dispersion and mixing process, so as to prevent the problem of low mixing efficiency due to a large amount of graphene and plastic raw materials mixed, and the problem of uneven mixing that is easy to occur. In this way, the mixing efficiency is improved by the mixing mechanism 4.

[0036] When in use, first, the heat preservation barrel 1 is used to support the granulation mechanism 2, the feeding assembly 3 and the driving mechanism 5, and then the feeding assembly 3 is used to put the graphene and plastic raw materials into the mixing mechanism 4. At this time, the heating tube inside the heat preservation barrel 1 works so that it can heat the graphene and plastic raw materials inside the mixing mechanism 4 into liquid, so as to change the molecular structure between the graphene and the plastic raw materials. At this time, the mixing barrel 1 41 and the mixing barrel 2 42 are used to mix the graphene and plastic raw materials twice. First, the mixing barrel 2 42 is used to preliminarily mix the graphene and plastic liquid. The mixed graphene and plastic liquid are discharged through the filter hole 43, and then enter the mixing barrel 1 41 for re-mixing. It is connected to the driving mechanism 5 through the gap baffle 44, so that it can gap-feed the graphene and plastic liquid to prevent the graphene and plastic liquid from being put into the mixing barrel 1 41 to affect the mixing work efficiency.

[0037] When the graphene and the plastic liquid enter the mixing barrel 41, since the liquid will enter the spiral blade 46, the driving shaft 51 is reversed at this time, and the graphene and the plastic liquid in the spiral blade 46 can be moved upward in turn, preventing the unmixed graphene and the plastic liquid in the mixing barrel 41 from entering the granulation mechanism 2, and further promoting the mixing between the graphene and the plastic liquid, thereby improving the mixing effect;

[0038] When it is necessary to discharge the material into the mixing barrel 41, the driving mechanism 5 drives the driving shaft 51 to rotate forward, so that it can quickly and evenly discharge the graphene and plastic liquid from the mixing barrel 41 into the granulating mechanism 2, thereby avoiding the problem of the spiral blade 46 being easily blocked and improving the efficiency of discharge.

[0039] In addition, the mixing cylinder 41 and the inner bottom wall of the heat preservation barrel 1 are provided with slide rails to ensure stability when the mixing cylinder 41 rotates.

[0040] In one embodiment, reference Figure 4 and Figure 5The feeding assembly 3 includes a feeding shell 31 fixed on the heat preservation barrel 1, a feeding hopper 32 is fixedly connected to the top of the feeding shell 31, a crushing roller 33 is rotatably connected to the inside of the feeding hopper 32 through a bearing, the two crushing rollers 33 are meshed with each other through gears, one end of one of the crushing rollers 33 is fixedly connected to a connecting shaft 34, the end of the connecting shaft 34 is drivingly connected to the end of the driving mechanism 5, a rotating shaft 35 is rotatably connected to the inside of the feeding shell 31 through a bearing, the end of the rotating shaft 35 is driven by the end of the crushing roller 33, a cam 36 is fixedly connected to the surface of the rotating shaft 35, a sieve plate 37 is attached to the surface of the cam 36, the sieve plate 37 slides inside the feeding shell 31, a return spring 38 is fixedly connected to the bottom of the sieve plate 37, and the end of the return spring 38 is fixed in the feeding shell 31.

[0041] With such a solution, when the graphene and the plastic raw material enter the interior of the feed component 3, the graphene and the plastic raw material can be crushed and mixed by the feed component 3, so as to promote the preliminary mixing of the graphene and the plastic raw material;

[0042] In specific operation, the graphene and plastic raw materials are first put into the feed hopper 32 fixed on the top of the feed shell 31, and then the crushing roller 33 inside the feed hopper 32 is driven to crush and mix the graphene and the plastic raw materials, and the connecting shaft 34 fixed by the crushing roller 33 is meshed and driven with the driving mechanism 5, so that the crushing roller 33 can be rotated synchronously, thereby ensuring synchronous drive while reducing energy loss. When the crushed graphene and plastic raw materials enter between the two crushing rollers 33 and fall into the insulation barrel 1, the crushing roller 33 drives the rotating shaft 35 to rotate synchronously, thereby The sieve plate 37 is reciprocated and shaken up and down, so that when the graphene and plastic raw materials are smaller than or equal to the holes in the sieve plate 37, they will automatically fall into the insulation barrel 1 and then enter the mixing mechanism 4. When they are larger than the holes in the sieve plate 37, the sieve plate 37 will compress the reset spring 38 during the descent process, so that the sieve plate 37 will shake up and down during the resetting process again, so as to shake the graphene and plastic raw materials that cannot be filtered to between the crushing rollers 33, so as to crush them again, so that they can be completely filtered. By crushing and mixing the graphene and plastic raw materials, the graphene and plastic raw materials can be preliminarily mixed, so as to facilitate more efficient production in the later stage.

[0043] In addition, the gear drive is a gear plate, so that when one of the crushing rollers 33 rotates, it can synchronously drive the other crushing roller 33 to rotate synchronously, so as to achieve staggered crushing, so that the crushing efficiency of graphene and plastic raw materials is better, the driving mechanism 5 and the connecting shaft 34 can be meshed with bevel gears, so as to facilitate better transmission efficiency, the crushing roller 33 and the rotating shaft 35 can be driven by a belt or chain to provide a power source for the rotating shaft 35.

[0044] In one embodiment, reference Figure 3 and Figure 6 and Figure 7 The driving mechanism 5 includes a driving shaft 51 that rotates inside the heat preservation barrel 1 through a bearing, the end of the driving shaft 51 passes through the interior of the mixing barrel 1 41 and the surface is respectively fixedly connected with a stirring scraper 1 52, an ultrasonic head 53 and a stirring scraper 2 54, the stirring scraper 1 52 and the ultrasonic head 53 rotate inside the mixing barrel 2 42, the stirring scraper 2 54 rotates inside the mixing barrel 1 41, and the surface of the driving shaft 51 is fixedly connected with a rotating assembly 55, wherein the rotating assembly 55 includes a fixed gear ring 551 fixed to the top wall of the heat preservation barrel 1, and the interior of the fixed gear ring 551 is meshed with a driven gear 5 52, the surface of the driven gear 552 is meshedly connected with the main gear 553, the middle part of the main gear 553 is fixedly connected to the driving shaft 51, the bottom of the driven gear 552 is fixedly connected with the fixing rod 554, the end of the fixing rod 554 is fixed to the top of the mixing barrel 41, the upper surface of the driving shaft 51 is provided with a reciprocating wire groove 56, the surface of the reciprocating wire groove 56 is bolted with a reciprocating plate 57, the bottom of the reciprocating plate 57 is fixedly connected with a filter plate 58 through a connecting rod, the middle part of the filter plate 58 is slidably connected with a guide rod 59, and the end of the guide rod 59 is fixed to the inner bottom wall of the mixing barrel 41.

[0045] By adopting such a scheme, the driving mechanism 5 is driven to stir and disperse the graphene thermal conductive plastic liquid, thereby accelerating the full dissolution of the graphene and the plastic itself, so that the inside of the plastic has the thermal conductive property of the graphene;

[0046] During the specific operation, the driving shaft 51 is first rotated by the driving unit. During the rotation of the driving shaft 51, the stirring scraper 1 52, the ultrasonic head 53 and the stirring scraper 2 54 are driven to rotate synchronously. During the rotation of the stirring scraper 1 52, the graphene thermal conductive plastic liquid inside the mixing barrel 2 42 can be initially stirred, and the graphene thermal conductive plastic liquid on the inner wall of the mixing barrel 2 42 can be scraped to prevent the graphene thermal conductive plastic liquid from adhering to the inside of the mixing barrel 2 42 and affecting the later discharge. During the rotation of the filter hole 43, ultrasonic vibration can be generated inside the graphene thermal conductive plastic liquid to accelerate the internal dispersion structure of the graphene, so as to better fully merge with the plastic liquid. During the rotation of the stirring scraper 2 54, the graphene thermal conductive plastic liquid inside the mixing barrel 1 41 can be stirred again to promote the full mixing of the graphene and the plastic liquid again.

[0047] When the driving shaft 51 rotates, the reciprocating wire groove 56 on the surface will rotate synchronously. Through the rotation of the reciprocating wire groove 56, the reciprocating plate 57 on the surface can be reciprocated up and down in a straight line. When the reciprocating plate 57 moves up and down, the filter plate 58 will be driven to move synchronously. When the filter plate 58 moves upward, the bubbles generated by the mixing between the graphene and the plastic liquid can be lifted upward for rupture treatment, so as to prevent the bubbles from being unable to be processed and affecting the mixing effect of the graphene and plastic liquid in the later stage. When the filter plate 58 moves downward, it can assist the feeding efficiency of the graphene and plastic liquid inside the mixing barrel 41, and improve the fullness of the feeding, so as to avoid the drop of the falling and affect the granulation effect in the later stage. At the same time, under the setting of the mixing mechanism 4, it can filter the larger particles between the graphene and the plastic liquid, so as to prevent the plastic from being completely melted into the liquid and discharged. Under the setting of the guide rod 59, it can play a guiding role in the displacement process of the reciprocating plate 57 and the filter plate 58.

[0048] When the driving shaft 51 rotates, the rotating component 55 will work synchronously. When the rotating component 55 works, the main gear 553 is driven to rotate through the driving shaft 51. When the main gear 553 rotates, the driven gear 552 is synchronously rotated. When the driven gear 552 rotates, the heat preservation barrel 1 fixed by the fixed rod 554 is driven to rotate. Since the driven gear 552 is engaged with the fixed gear ring 551, it can guide and limit the driven gear 552 when it rotates, so as to ensure the stability of the rotation of the heat preservation barrel 1. The rotation of the heat preservation barrel 1 can further accelerate the full fusion between graphene and plastic liquid.

[0049] In addition, the driving element is driven by an electric motor.

[0050] In one embodiment, reference Figure 1 , Figure 3 , Fig. 9The granulation mechanism 2 includes a granulation cylinder 21 fixed at the bottom of the heat preservation barrel 1. The interior of the granulation cylinder 21 is connected to a auger rod 22 through a driving part. The end of the auger rod 22 passes through the granulation cylinder 21 and is fixedly connected to a cutting knife 23. A plurality of discharge holes 24 are opened at the end of the granulation cylinder 21. The plurality of discharge holes 24 are arrayed at equal distances along the surface of the granulation cylinder 21. A baffle 25 is fixedly connected to the end of the granulation cylinder 21. The baffle 25 is located on one side of the discharge hole 24.

[0051] With such a scheme, when the graphene heat-conducting plastic liquid enters the granulating mechanism 2, the graphene heat-conducting plastic liquid can be transported by the granulating mechanism 2. Since the granulating mechanism 2 is at a certain distance, the graphene heat-conducting plastic liquid will be naturally cooled during the transportation process, and then the granulation work can be carried out by cutting, so as to facilitate the subsequent operation.

[0052] During specific operation, the graphene thermal conductive plastic liquid is first collected through the granulation barrel 21, and then driven by the auger rod 22 to transport the graphene thermal conductive plastic liquid in the granulation barrel 21. At this time, under the transmission of the auger rod 22, the graphene thermal conductive plastic liquid can be squeezed out through the discharge hole 24, and the cutting knife 23 can be synchronously driven to rotate and cut when the auger rod 22 rotates, so as to cut and granulate the long strips of graphene thermal conductive plastic liquid, and the baffle 25 is used to guide and discharge the cut graphene thermal conductive plastic granules, so as to facilitate centralized collection.

[0053] In addition, the middle part of the auger rod 22 can cool the graphene thermal conductive plastic liquid by air cooling or water cooling, so as to facilitate the granulation work.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
