[0018] 1. In this utility model, a mixing component is provided. During use, the radar wave absorbing coating to be mixed is fed into the proportioning module through the inlet. Then, the proportioning module feeds the metered and proportioned radar wave absorbing coating raw material into the mixing tank through the outlet at the bottom of the proportioning module and the inlet at the top of the mixing tank. The motor is then started, driving the cooling fan, which in turn drives the connecting shaft and the mixing blades. The mixing blades mix the radar wave absorbing coating raw material, and the cooling fan cools the motor simultaneously to prevent the motor temperature from rising during prolonged operation and affecting its service life. If the motor temperature becomes too high, the connecting pipe and cooling pipe of the cooler are connected.

The cold air discharged from the refrigeration pipe further dissipates heat from the motor, and the lubricating cotton further lubricates the connecting shaft to prevent reduced smoothness and ensure proper operation. Therefore, this design not only increases the lifespan of the equipment but also ensures the electromagnetic function of the absorption coating and the preparation efficiency.

The mixing blade 69 is located inside the mixing tank 3. The top of the mixing tank 3 has a hole. The top end of the connecting shaft 68 passes through the hole in the protective shell 61. The side wall of the lubricating cotton 66 is fixedly connected to the top hole of the mixing tank 3.

[0028] The specific implementation method is as follows: In use, the radar wave absorbing coating to be mixed is fed into the proportioning module 4 through the feed port 5. Then, through the proportioning module 4, the metered and proportioned radar wave absorbing coating raw material is fed into the mixing tank 3 through the discharge port at the bottom of the proportioning module 4 and the feed hole at the top of the mixing tank 3. Then, the motor 64 is started, which drives the cooling fan 65, thereby driving the connecting shaft 68 and the mixing blade 69. The mixing blade 69 mixes the radar wave absorbing coating raw material. At the same time, the cooling fan 65 dissipates heat from the motor 64 to prevent the motor 64 from overheating during long-term operation and affecting its service life. When the temperature of the motor 64 is too high, the connecting pipe of the cooler is connected to one end of the cooling pipe 62, and the cold air is sent into the cooling pipe 62 and then discharged from the air outlet 63 to further dissipate heat from the motor 64. At the same time, the connecting shaft 68 is rotated and lubricated by the lubricating cotton 66 to prevent the smoothness of the connecting shaft 68 from decreasing and affecting its use.

[0030] The specific implementation method is as follows: while mixing the radar wave absorbing coating, the electric push rod 71 is activated, which drives the fixed plate 74, thereby driving the mixing tank 3, causing the mixing tank 3 to move back and forth on the sliding plate 75, thereby further mixing the radar wave absorbing coating raw materials inside the mixing tank 3 and improving the mixing efficiency.

[0031] Working principle: In use, the radar wave absorbing coating material to be mixed is fed into the proportioning module 4 through the feed inlet 5. Then, the proportioning module 4 feeds the metered and proportioned radar wave absorbing coating material into the mixing tank 3 through the discharge port at the bottom of the proportioning module 4 and the feed hole at the top of the mixing tank 3. The motor 64 is then started, driving the cooling fan 65, which in turn drives the connecting shaft 68 and the mixing blades 69. The mixing blades 69 mix the radar wave absorbing coating material, and simultaneously, the cooling fan 65 cools the motor 64, preventing overheating during prolonged operation and extending its service life. When the temperature of the machine 64 is too high, the connecting pipe of the cooler is connected to one end of the cooling pipe 62, and the cold air is sent into the cooling pipe 62 and then discharged from the outlet 63 to further dissipate heat from the motor 64. While the connecting shaft 68 is rotating, it is lubricated by the lubricating cotton 66 to prevent the smoothness of the connecting shaft 68 from decreasing and affecting its use. While mixing the radar wave absorbing coating, the electric push rod 71 is activated, which drives the fixed plate 74, thereby driving the mixing tank 3 to move back and forth on the sliding plate 75, thereby further mixing the radar wave absorbing coating raw materials inside the mixing tank 3 and improving the mixing efficiency.
