A mixing block 8 is provided inside the No. 1 mixing chamber 9, and a No. 2 mixing chamber 11 is provided inside the reaction channel 2. The material passes through the diverter block 10, and a part of it enters the side channel 7, and then enters the No. 1 mixing chamber 9 through the side channel 7. The mixing block 8 diverts the material and then mixes it to increase the mixing effect and slow down the flow rate of the material. When the material in the side channel 7 flows out, it merges with the material in the reaction channel 2 in the No. 2 mixing chamber 11. When materials with different flow rates converge, a greater counter-force will be generated, making the material mixing more even.

[0023] In this embodiment: the material passes through the diverter block 10, and a part of it enters the side channel 7, and then enters the No. 1 mixing chamber 9 through the side channel 7. The mixing block 8 diverts the material and then mixes it to increase the mixing effect and slow down the flow rate of the material. When the material in the side channel 7 flows out, it merges with the material in the reaction channel 2 in the No. 2 mixing chamber 11. When materials with different flow rates converge, they will generate a greater impact force, making the material mixing more even.

[0024] Please refer to Figure 3 The supporting mechanism 3 includes a fixed plate 301, which is fixed at the bottom of the base plate 1. A sliding groove 305 is provided on one side of the fixed plate 301. The internal sliding connection of the sliding groove 305 is a limiting rod 302. The middle part of the limiting rod 302 is fixedly connected with a slider 303, and the slider 303 slides inside the fixed plate 301. A screw 304 is rotatably connected to the middle position inside the fixed plate 301. The screw 304 is connected to the inside of the thread. The thread is arranged at the middle position of the slider 303. Connecting rods 306 are rotatably connected to both ends of the limiting rod 302. A fixed block 308 is fixedly connected to the bottom of the base plate 1. A supporting plate 307 is rotatably connected to one side of the fixed block 308. One side of the supporting plate 307 is rotatably connected to the connecting rod 306. The screw 304 is rotated to make the slider 303 slide in the fixed plate 301. When the slider 303 slides, it pushes the connecting rod 306 to rotate, thereby changing the angle of the supporting plate 307.

[0025] In this embodiment: the screw rod 304 is rotated to make the slider 303 slide in the fixed plate 301 . When the slider 303 slides, it pushes the connecting rod 306 to rotate, thereby changing the angle of the support plate 307 .

[0026] Please refer to Figure 2 An intermediate feed port 6 is provided on one side of the reaction channel 2, through which new materials can be added after other materials have been mixed and reacted to a certain extent.

[0027] In this embodiment, new materials can be added through the intermediate feed port 6 after other materials have been mixed and reacted to a certain extent.

[0028] Please refer to Figure 4 There is a gap between the No. 1 mixing chamber 9 and the mixing block 8. After the material enters the No. 1 mixing chamber 9, the material is diverted and then merged through the mixing block 8, thereby increasing the mixing effect of the material.

[0029] In this embodiment, after the material enters the first mixing chamber 9, the material is divided and then merged by the mixing block 8, thereby increasing the mixing effect of the material.

[0030] In the utility model, the working principle of the device is as follows:

[0031] When in use, the screw 304 is rotated to make the slider 303 slide in the fixed plate 301. When the slider 303 slides, it will push the connecting rod 306 to rotate, thereby changing the angle of the support plate 307, so that the substrate 1 always remains horizontal on the detection table, and then the material is put into the feed port 4. The material is collected into the reaction channel 2 through the feed port 4 for mixing. After passing through the diverter block 10, a part of the material enters the side channel 7 and enters the No. 1 mixing chamber 9 through the side channel 7. The mixing block 8 diverts the material and then mixes it, which can increase the mixing effect and slow down the flow rate of the material. After the material flows out of the side channel 7, it is collected in the No. 2 mixing chamber 11 with the material in the reaction channel 2. Materials with different flow rates will produce a greater counter-force when they are collected, so that the mixing effect is better and the material is mixed more evenly. The mixed material finally flows out from the discharge port 5.
