[0003] When pouring the existing filler structure, it is more common to pour it all at once and then stir and mix it, which will cause agglomeration. If the filler content is too high, it will cause the filler to settle, which will cause the filler to not be evenly dispersed, thereby reducing the thermal conductivity. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model proposes a filler structure for preparing high thermal conductivity insulating epoxy molding compound. In the prior art, the filler in the filler structure is unevenly mixed.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0022] Combination Figure 1 A filler structure for preparing a high thermal conductive insulating epoxy molding compound comprises a bracket 1, a cylinder 2 arranged inside the bracket 1, a cylinder cover 21 arranged on one side of the cylinder 2, a motor 3 is fixedly mounted on one side of the cylinder cover 21, and a stirring shaft 31 is fixedly mounted on the output end of the motor 3, and a feeding component 4 for adding fillers is arranged on the outer surface of the cylinder 2.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 5 The feeding component 4 includes a placement pool 41 arranged on the outer surface of the cylinder 2, a filter screen 42 arranged inside the placement pool 41, and a filling bottle 43 arranged above the filter screen 42. The outer surface of the filling bottle 43 is sleeved with a fixing ring 44, a moving column 45 is fixedly installed on one side of the fixing ring 44, a slider 46 is fixedly installed on one side of the moving column 45, and an electric push rod 47 is fixedly installed on one side of the slider 46. The fixed end of the electric push rod 47 is fixedly connected to one side of the placement pool 41, and the bottom of the placement pool 41 is connected to the inside of the cylinder 2. The filling bottle 43 is moved inside the placement pool 41 through the extension and retraction of the electric push rod 47, so that the filler can be evenly sprinkled in the cylinder 2, making mixing easier and the filler is not easy to gather. The filter screen 42 can prevent the larger seasonings that are gathered into a mass from entering the cylinder 2, and can reduce the drop rate of the filler, so that the filler can be better mixed with other mixtures, thereby improving the thermal conductivity.

[0026] A connecting rod 5 is provided on one side of the movable column 45, and a brush 51 is threadedly connected to one end of the connecting rod 5. The bottom of the brush 51 contacts the upper surface of the filter screen 42. Since the movable column 45 is moved by the electric push rod 47, the connecting rod 5 and the brush 51 will move accordingly. Because the bottom of the brush 51 contacts the upper surface of the filter screen 42, some clumped fillers can be pushed apart and the fillers can be prevented from sticking to the filter screen 42.

[0027] The outer surface of the stirring shaft 31 is provided with a turning assembly 6, which includes a gear A61 sleeved on the outer surface of the stirring shaft 31, a gear B62 meshingly connected to one side of the gear A61, one side of the gear B62 meshingly connected to an internal gear 63, and a rotating shaft 64 passing through the center of the gear B62. The outer surface of the rotating shaft 64 and the outer surface of the stirring shaft 31 are both provided with spiral blades 65. Since the raw material has a certain viscosity, it can be better mixed by two sets of spiral blades 65. In addition, the motor 3 drives the stirring shaft 31 to rotate, so the gear A61 rotates and drives the gear B62 to rotate. Because one side of the gear B62 is meshingly connected to the internal gear 63, the rotating shaft 64 will make a circular motion with the stirring shaft 31 as the center, thereby turning the mixture at the bottom of the cylinder 2 and adhering to the inner wall, reducing precipitation, and increasing the uniform dispersion of the filler.

[0028] A support column 7 is threadedly connected to one side of the cylinder cover 21, and a partition 71 is arranged on one side of the support column 7. An annular groove is opened on the surface of the partition 71, and a silicone baffle 72 is arranged inside the annular groove. The annular groove corresponds to the rotating shaft 64. The partition 71 and the silicone baffle 72 can block most of the mixture from entering the partition 71 to avoid erosion of the gear A61, the gear B62 and the internal gear 63.

[0029] All components inside the cylinder 2 are provided with an anti-stick coating to prevent sticking.

[0030] A feeding cylinder 8 is arranged on one side of the cylinder cover 21, and a discharging cover 9 is hingedly connected to one side of the cylinder cover 21, so as to facilitate the putting in of the mixture to be filled with fillers and the pouring out of the mixture to which the fillers have been added.

[0031] Specifically, the mixture to be added with fillers is put into the cylinder 2 from the feed barrel 8, and then the motor 3 is started to drive the stirring shaft 31 to rotate, and then the filler bottle 43 is moved inside the placement pool 41 by the extension and contraction of the electric push rod 47, so that the filler can be evenly sprinkled in the cylinder 2, making mixing easier and the filler is not easy to aggregate. The filter screen 42 can prevent the aggregated and larger seasonings from entering the cylinder 2, and can reduce the drop rate of the filler, so that the filler can be better mixed with other mixtures, and the thermal conductivity is improved. Because a connecting rod 5 and a brush 51 are provided on one side of the moving column 45, the connecting rod 5 and the brush 51 will move accordingly. Because the bottom of the brush 51 is in contact with the upper surface of the filter screen 42, some agglomerated fillers can be pushed apart, and the filler can be prevented from sticking to the filter screen 42. In addition, by Since the raw material has a certain viscosity, the motor 3 drives the stirring shaft 31 to rotate, so the gear A61 rotates, and drives the gear B62 to rotate. Because one side of the gear B62 is meshed with the internal gear 63, the rotating shaft 64 will make a circular motion with the stirring shaft 31 as the center, and the outer surface of the rotating shaft 64 and the outer surface of the stirring shaft 31 are both provided with spiral blades 65, so that the mixture at the bottom of the cylinder 2 and adhered to the inner wall can be turned over, reducing precipitation and increasing the uniform dispersion of the filler. A partition 71 and a silicone baffle 72 are also provided therein to prevent most of the mixture from entering the partition 71 to avoid erosion of the gear A61, the gear B62 and the internal gear 63. Because all components inside the cylinder 2 are provided with an anti-stick coating, sticking can be prevented, thereby reducing equipment loss. Finally, the mixture with the filler added is poured out from the discharge cover 9.
