[0002] A mixing device for thermally conductive materials is used to mix and stir these materials, which are a new type of industrial material. These materials were designed in recent years to meet the heat transfer requirements of equipment, offering excellent performance and reliability. They are suitable for various environments and requirements, provide effective solutions for potential heat conduction problems, and greatly contribute to the high integration and ultra-small, ultra-thin design of equipment. These thermally conductive products are increasingly used in many products, improving their reliability. Examples include graphene, thermally conductive adhesives, graphene preparation equipment, thermal conductivity testing instruments, heating elements, thermally conductive silicone sheets, thermally conductive insulating materials, thermally conductive interface materials, thermally conductive silicone cloth, thermally conductive tape, thermally conductive grease, thermal paste, heat dissipation paste, thermal grease, heat dissipation oil, heat dissipation film, and thermally conductive film.

[0003] For example, the authorized patent with publication number CN214915460U (Heat-conducting material stirring device) includes a frame, a base, a lifting mechanism, a stirring motor, a stirring rod, a stirring tank, and a vacuum suction mechanism. A support arm is mounted on the lower side of the frame, and a tilting mechanism is mounted on the support arm and connected to the side wall of the stirring tank. The lifting mechanism is mounted on the frame, the stirring motor is mounted on the lifting mechanism, the stirring rod is mounted at the output end of the stirring motor and extends into the stirring tank during stirring, the base supports the stirring tank, and the lower side of the frame has a clearance space to facilitate the rotation of the stirring tank.

[0049] A method for stirring a thermally conductive material includes the following steps:

[0050] 1) Control panel 9 controls the operation of the second motor 34, which drives the drive gear 37 to rotate.

The heating layer 26 controls the temperature of the mixture in the inner cavity.

[0052] 3) The heat-conducting material after stirring and mixing is drawn out by the feed pump 24 and discharged through the feed head 25.

[0053] Working principle: When the equipment is in use, the control panel 9 controls the second motor 34 to run, which drives the drive gear 37 to rotate. The drive gear 37 and the driven gear 35 are connected by a transmission gear 36, which drives the screw 32 to rotate. The screw 32 is connected to the guide lug 33 by a lead screw, which controls the guide plate 17 to move the mixing tank 14 laterally. This adjusts the metering of the second feed hopper 18, the first feed hopper 15, and the third feed hopper 21 at the top of the mixing tank to the bottom of the first guide cylinder 3, the second guide cylinder 6, and the third guide cylinder 7, respectively.

These materials can be guided separately through a first guide cylinder 3, a third guide cylinder 7, and a second guide cylinder 6. Furthermore, the mixing tank 14 of this invention can move laterally on a guide rail, greatly solving the problem of high costs associated with multiple mixing tanks during the mixing process. This also makes the batching process more convenient and significantly increases the types of materials that can be mixed.
