[0029] The grinding assembly comprises a grinding box 19 fixedly connected to the outer right side of the base 1, a second motor 21 arranged on the outer back side of the grinding box 19, a first gear 22 fixedly connected to the output end of the second motor 21, two transmission rods 24 rotatably connected to the inner sides of the grinding box 19, the first gear 22 fixedly connected to the outer back side of the left transmission rod 24, a second gear 23 fixedly connected to the outer back side of the right transmission rod 24, the first gear 22 engaged with the second gear 23, two grinding rollers 25 fixedly connected to the outer sides of the two transmission rods 24, the grinding rollers 25 facilitating grinding of the epoxy heat-conducting filler, a conveying pipeline 27 fixedly connected to the bottom of the grinding box 19 and arranged in the inner part of the dispersion barrel 3, the conveying pipeline 27 facilitating conveying of the ground epoxy heat-conducting filler, a mounting ring 20 fixedly connected to the outer back side of the grinding box 19 and in which the second motor 21 is fixedly arranged, the mounting ring 20 facilitating fixation of the second motor 21, and a feeding port 26 fixedly connected to the upper part of the grinding box 19 and facilitating feeding of the epoxy heat-conducting filler.

[0030] Specifically, in the production and dispersion process of the epoxy heat-conducting filler, first, the epoxy resin is placed in the inner part of the dispersion barrel 3, and then the epoxy heat-conducting filler is fed into the inner part of the grinding box 19 through the feeding port 26. The filler can be a heat-conducting material such as aluminum oxide or boron nitride, and the purpose is to finely grind the filler to an appropriate particle size through grinding, so that it is easier to be uniformly dispersed in the epoxy resin subsequently. Then, the second motor 21 is started, and the first gear 22 fixedly arranged at the output end of the second motor 21 starts to rotate. The rotation of the first gear 22 drives the second gear 23 engaged with the outer part of the first gear 22 to rotate synchronously. With the rotation of the first gear 22 and the second gear 23, the two transmission rods 24 fixedly arranged in the inner part are driven to rotate. The two transmission rods 24 are connected to the two grinding rollers 25 fixedly arranged on the outer part. When the transmission rods 24 rotate, the grinding rollers 25 are driven to rotate synchronously. The high-speed rotation of the grinding rollers 25 produces a strong grinding effect on the epoxy heat-conducting filler, further reducing the size of the filler particles, breaking the agglomerates, and finally achieving uniform refinement. The ground epoxy heat-conducting filler is transmitted to the inner part of the dispersion barrel 3 through the conveying pipeline 27 and combined with the epoxy resin. Finally, the driving assembly is started, and the driving assembly drives the rotation of the rotating rod 10, thereby driving the dispersion rods 11 fixedly arranged around the outer part of the rotating rod 10 to rotate synchronously. The rotation of the dispersion rods 11 forms a strong shearing force and mixing force, promoting the epoxy heat-conducting filler to be fully dispersed in the epoxy resin, and the filler particles are uniformly distributed in the resin matrix. In the production of the epoxy heat-conducting filler, the filler is ground, which makes it easier to be uniformly dispersed in the epoxy resin. This ensures uniform distribution of the filler in the matrix material and improves the overall heat-conducting effect of the composite material.

[0031] Reference Figure 3 ,Figure 4 and Figure 6 The dismounting and assembling component comprises two fixed rods 29 fixedly connected at the two sides of the inner part of the mounting block 9, two sliding blocks 12 slidingly connected at the outer part of the two fixed rods 29, an extension rod 13 fixedly connected at the bottom of the inner right part of the mounting block 9, a spring 14 sleeved at the outer part of the extension rod 13, a handle 15 fixedly connected at the upper part of the sliding block 12, and an insertion block 16 fixedly connected at the outer left side of the sliding block 12. The insertion block 16 is convenient for fixing the rotating rod 10. A first through hole 18 is formed in the inner part of the mounting block 9, and the insertion block 16 is slidingly connected in the first through hole 18. The first through hole 18 is convenient for the movement of the insertion block 16. A second through hole 28 is formed in the upper part of the mounting block 9, and the handle 15 is slidingly connected in the second through hole 28. The second through hole 28 is convenient for the movement of the handle 15. A clamping groove 17 is formed in the inner part of the rotating rod 10, and the insertion block 16 is inserted into the clamping groove 17, thereby improving the stability of the rotating rod 10.

[0032] Specifically, in the process of cleaning the dispersion rod 11, first, the operator starts the air cylinder 6, and slowly moves the dispersion rod 11 with the rotating rod 10 out of the inner part of the dispersion barrel 3. The air cylinder 6 pushes the rotating rod 10 and the dispersion rod 11 to move upwards to a safe and convenient position. Then, the worker pulls the handle 15, and the handle 15 is connected to the bottom sliding block 12. The sliding block 12 moves at the outer part of the two fixed rods 29. When the sliding block 12 moves, it will generate pressure on the outer fixed extension rod 13, so that the extension rod 13 gradually shrinks, and the outer sleeved spring 14 is compressed at the same time. At this time, the spring 14 is deformed under the action of external force, providing elastic preparation for the reset of the subsequent insertion block 16. At this time, the sliding block 12 continues to move, driving the insertion block 16 fixed on the outer side thereof to separate from the clamping groove 17. The dispersion rod 11 and the rotating rod 10 will be completely separated from the mounting block 9, and the operator can easily take them out of the device. After the dispersion rod 11 is taken out of the mounting device, the operator can transfer it to the cleaning area, and use the specified cleaning tool and solvent to thoroughly clean the surface and the residual materials and fillers inside the dispersion rod 11. When installing, the operator first inserts the rotating rod 10 into the inner part of the mounting block 9, and then loosens the handle 15. With the help of the reaction force of the spring 14, the insertion block 16 will automatically insert into the clamping groove 17, thereby fixing the dispersion rod 11 at the correct installation position. Through this design, the equipment realizes the convenient dismounting and assembling of the dispersion rod 11, facilitates regular cleaning and maintenance, removes the residual materials or fillers on the surface of the equipment during the cleaning process, effectively prevents the pollution of impurities to the subsequent batch production, and improves the purity and quality of the product.

[0033] Working principle: in the production of epoxy heat-conducting filler dispersion, first, the epoxy resin is placed in the inside of the dispersion barrel 3, then the epoxy heat-conducting filler is put into the inside of the grinding box 19 through the feed port 26, then the second motor 21 is started, the second motor 21 rotates with the fixed output end of the first gear 22, the first gear 22 rotates with the second gear 23 engaged outside, the two transmission rods 24 are rotated with the inside fixed during the rotation of the first gear 22 and the second gear 23, the two grinding rollers 25 are rotated with the outside fixed during the rotation of the two transmission rods 24, the epoxy heat-conducting filler put into the inside of the grinding box 19 is ground through the rotation of the two grinding rollers 25, then the ground epoxy heat-conducting filler is conveyed to the inside of the dispersion barrel 3 through the conveying pipeline 27, then the dispersion rod 11 fixed around the outside of the rotating rod 10 is rotated through the driving assembly to complete the dispersion operation of the epoxy heat-conducting filler, which realizes the convenience of grinding the epoxy heat-conducting filler during the production of the epoxy heat-conducting filler, makes it easier to disperse uniformly in the epoxy resin, which can ensure the uniform distribution of the filler in the matrix material and improve the overall heat-conducting effect of the composite material.

[0034] When the dispersion rod 11 needs to be cleaned, first, the rotating rod 10 and the dispersion rod 11 are moved out of the inside of the dispersion barrel 3 through the cylinder 6, then the sliding block 12 fixed at the bottom is moved outside the two fixed rods 29 by pulling the handle 15, the telescopic rod 13 fixed outside is extruded when the sliding block 12 moves, the spring 14 outside the telescopic rod 13 is extruded when the telescopic rod 13 contracts, so that the spring 14 is deformed under stress, and at the same time, the insertion block 16 fixed outside the left side is moved when the sliding block 12 moves, so that the insertion block 16 is separated from the inside of the clamping groove 17, so that the rotating rod 10 and the dispersion rod 11 can be taken out of the inside of the mounting block 9 for cleaning, during installation, the rotating rod 10 is inserted into the inside of the mounting block 9, then the handle 15 is loosened, the insertion block 16 is inserted into the inside of the clamping groove 17 under the reaction force of the spring 14, which realizes the convenience of disassembling and cleaning the dispersion rod 11, can remove residual materials or fillers, prevents impurities from mixing into subsequent batches of production, thereby improving the purity and quality of the product.
