[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a mixing device for preparing electronic potting compound, comprising: a mixing tank 1, a stirring frame 2 disposed inside the mixing tank 1, a fixed bearing 3 disposed inside the mixing tank 1, a scraping ring 4 disposed on the inner circumferential surface of the fixed bearing 3, and the stirring frame 2 being inserted into the scraping ring 4; a cover 5, on the surface of the cover 5 being provided with a drive motor 6 and a vacuum pump 7;

[0022] In use, the drive motor 6 can be started to mix the sealant in the mixing tank 1 through the stirring frame 2. During the mixing process, the vacuum pump 7 evacuates the air from the mixing tank 1. After the mixing is completed, the stirring frame 2 is stuck in the scraping ring 4 on the inner ring surface of the fixed bearing 3. The scraping ring 4 scrapes off the sealant adhering to the outer wall of the stirring frame 2, preventing the stirring frame 2 from having too much sealant adhering to it after the mixing is completed. This avoids the problem of material waste caused by a lot of adhesive on the surface when the stirring frame 2 is removed.

[0023] Example 2: Based on Example 1, in order to reduce the waste of potting compound, a scraper ring 4 is provided with a symmetrical structure and fixedly installed on the inner ring surface of the fixed bearing 3. The scraper ring 4 has two sets of symmetrical slots on its surface. A scraper 10 is fixedly installed directly below the slots. The scraper ring 4 can rotate in the mixing tank 1. A drive shaft 11 is fixedly installed in the middle of the mixing frame 2. The two ends of the mixing frame 2 are locked in the slots on the surface of the scraper ring 4. The outer walls of the two ends of the mixing frame 2 are in contact with the side walls of the scraper 10.

[0024] To reduce material waste, during mixing, the required materials are added to the mixing tank 1. Then, the mixing frame 2 and the mixing disc 16 are driven to rotate, thereby fully mixing the potting compound in the mixing tank 1. The mixing frame 2 is completely locked in the scraper ring 4 on the inner ring surface of the fixed bearing 3. When the mixing frame 2 rotates, the scraper ring 4 also rotates. After the potting compound is mixed, the mixing frame 2 is removed from the mixing tank 1. During the removal process, because the mixing frame 2 is completely locked in the scraper ring 4, and the scraper 10 below the scraper ring 4 is completely in contact with the outer wall of the mixing frame 2, the scraper 10 scrapes the potting compound adhering to the outer wall of the mixing frame 2 into the mixing tank 1, thereby reducing the waste of potting compound.

[0025] Example 3: Based on Example 2, a cover 5 is provided for easy mixing. A drive motor 6 is fixedly installed on the surface of the cover 5, and a drive shaft 11 is fixedly connected below the drive motor 6. A hole is opened on the outer wall surface of the cover 5, and a vacuum pump 7 is fixedly installed directly above the hole. An installation groove is opened on the inner wall of the mixing barrel 1, and a fixed bearing 3 is provided in the installation groove. The outer ring surface of the fixed bearing 3 is fixedly connected to the inner wall of the installation groove. A groove is opened on the upper inner wall of the mixing barrel 1, and the cover 5 can fit against the outer wall of the groove. A discharge pipe 8 is fixedly installed at the lower end of the mixing barrel 1, and a sealing plate 9 is fixedly installed at the lower end of the discharge pipe 8.

[0026] To facilitate mixing, a vacuum pump 7 is installed above the cap 5. During the mixing process, the vacuum pump 7 continuously pumps air out of the mixing tank 1, thereby reducing the air pressure inside the tank, reducing the possibility of air bubbles mixing into the material, and improving the uniformity and density of the mixture.

[0027] Two sets of fixing tubes 12 are sleeved on the outer wall of the drive shaft 11. The fixing tube 12 includes a first half tube 13, a second half tube 14 and a fixing screw 15. The first half tube 13 and the second half tube 14 are symmetrically sleeved on the drive shaft 11. The fixing screw 15 connects the first half tube 13 and the second half tube 14. A mixing disc 16 is fixedly installed on the outer wall of the fixing tube 12. A number of circumferentially equidistant stirring teeth are fixedly installed on the outer wall of the mixing disc 16.

[0028] To facilitate mixing, when installing the mixing disc 16, the first half-tube 13 and the second half-tube 14 are fitted onto the drive shaft 11 and fixed to the drive shaft 11 by the fixing screw 15. If the mixing disc 16 needs to be replaced or its position adjusted, the fixing screw 15 can be removed to remove the fixing tube 12 from the drive shaft 11, thus facilitating overall mixing.

[0029] In actual use, the drive motor 6 can be started to mix the sealant in the mixing tank 1 through the stirring frame 2. During the mixing process, the vacuum pump 7 evacuates the air from the mixing tank 1. After the mixing is completed, the stirring frame 2 is stuck in the scraping ring 4 on the inner ring surface of the fixed bearing 3. The scraping ring 4 scrapes off the sealant attached to the outer wall of the stirring frame 2, preventing the stirring frame 2 from having too much sealant attached after the mixing is completed. This avoids the problem of material waste caused by a lot of adhesive on the surface when the stirring frame 2 is taken out.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
