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 , Figure 2 and Figure 3 A mixing device for producing high thermal conductive insulating epoxy molding compound comprises a tank body 1, a tank cover 2 arranged on the upper surface of the tank body 1, a motor 3 is fixedly mounted on the upper surface of the tank cover 2, and a stirring shaft 31 is arranged at the output end of the motor 3, a cleaning component 4 is arranged inside the tank body 1, and a heating component 5 is arranged on the outer surface of the tank body 1.

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

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 5 The cleaning component 4 includes a gear A41 sleeved on the outer surface of the stirring shaft 31, a gear B42 meshingly connected to one side of the gear A41, and a connecting rod 43 passing through the center of the gear B42. The outer surface of the connecting rod 43 is sleeved with a silicone brush 44, and the outer surface of the silicone brush 44 contacts the inner wall of the tank body 1. The outer surface of the connecting rod 43 is sleeved with a ring 45, and a micro fan is arranged inside the ring 45. When the mixture is mixed inside the tank body 1, the tank cover 2 is opened and the connecting rod 43 is installed to the center of the gear B42. At this time, the mixture remaining on the inner wall of the tank body 1 is in a flowing state. If it is flushed with clean water, the plastic in the wet state will be The sealing material residues often have a high adhesion force and adhere to the surface. They will also diffuse or dissolve during the cleaning process. Therefore, the stirring shaft 31 is driven to rotate by starting the motor 3, and the gear B42 is driven to rotate by the gear A41, so that the connecting rod 43 rotates. Because there is residual heat in the tank body 1 after mixing, the air circulation can be accelerated by the micro fan, so as to quickly dry the mixture adhered to the inner wall of the tank body 1, and then the dried residue is scraped off by the silicone brush 44. Because after drying, the adhesion of the plastic sealing material residues will be reduced, it is easier to become independent solid particles and easier to fall off from the surface, so it can be removed more thoroughly.

[0026] A circular groove 421 and a groove 422 are provided at the center of the gear B42. A spring 6 is fixedly installed on the inner wall of the groove 422. A ball 61 is fixedly installed at one end of the spring 6. A circular groove 421 is also provided on the outer surface of the connecting rod 43. The circular groove 421 is engaged with the ball 61. When cleaning is required, the connecting rod 43 is inserted into the center of the gear B42 so that the ball 61 is engaged with the circular groove 421 on the outer surface of the connecting rod 43, so that the connecting rod 43 can rotate together with the gear B42.

[0027] The internal thread of the tank cover 2 is connected with a partition 7, and the gear A41 and the gear B42 are both arranged on the upper surface of the partition 7. The outer surface of the tank body 1 is provided with a feed barrel 11, which provides support for the gears A41 and B42 through the partition 7 without affecting the feeding.

[0028] The outer surface of the tank body 1 is provided with a heat-insulating layer 8, which helps to maintain the stability of the temperature inside the mixing device, avoid the influence of temperature fluctuations on the materials, and improve production efficiency and product quality.

[0029] The heating assembly 5 includes a heating tube 51 wrapped around the outer surface of the tank body 1. One end of the heating tube 51 passes through the insulation layer 8 and is connected to the outside. When mixing, it is necessary to do so at high temperature. The heating tube 51 wrapped around the outer surface of the tank body 1 can make the heating more uniform.

[0030] A discharge barrel 9 is disposed inside the tank body 1 , and a valve is disposed inside the discharge barrel 9 , so that the mixed mixture flows out from the discharge barrel 9 .

[0031] Specifically, various raw materials enter from the feed barrel 11 on the outer surface of the tank body 1, and are driven by the motor 3 to rotate and mix the stirring shaft 31. After the mixing is completed, the raw materials flow out from the discharge barrel 9. Then, the tank cover 2 is opened to install the connecting rod 43 to the center of the gear B42, so that the ball 61 is engaged with the circular groove 421 on the outer surface of the connecting rod 43, so that the connecting rod 43 can rotate together with the gear B42. Since the mixing is carried out at a high temperature and the outer surface of the tank body 1 is provided with a heat-insulating layer 8, the mixture remaining on the inner wall of the tank body 1 is in a flowing state. If it is flushed with clean water, the plastic sealing material residue in a wet state will flow out. It tends to have a high adhesion force and adheres to the surface. It will also diffuse or dissolve during the cleaning process. Therefore, the stirring shaft 31 is driven to rotate by starting the motor 3, and the gear A41 drives the gear B42 to rotate, so that the connecting rod 43 rotates. Because there is residual heat in the tank body 1 after mixing, the micro fan can accelerate the air circulation, thereby quickly drying the mixture adhered to the inner wall of the tank body 1, and then the dried residue is scraped off by the silicone brush 44. Because after drying, the adhesion of the plastic sealing material residue will be reduced, it is easier to become independent solid particles, and it is easier to fall off from the surface, so it can be removed more thoroughly.
