At this time, the screening component can effectively screen the raw materials, so that larger particle raw materials can be screened and filtered, thereby effectively improving the uniformity of the particle raw materials during mixing and the quality of the raw materials after mixing. When the raw materials fall into the mixing barrel 2, the stirring component starts to run. At this time, the stirring component can effectively stir and mix the raw materials inside the mixing barrel 2. While the stirring component is running, the driving component also starts to run synchronously. At this time, the driving component can drive the mixing barrel 2 to rotate synchronously in the opposite direction, thereby further improving the mixing effect of the raw materials. The stirring component will also drive the scraping component to rotate synchronously. At this time, the scraping component can effectively scrape the particles adhered to the inner wall of the mixing barrel 2, thereby preventing the waste of raw materials, etc., and preventing the particles adhered to the inner wall of the mixing barrel 2 from affecting the mixing of other particles. When the raw materials are mixed, the solenoid valve 10 is opened.

When it is necessary to mix the granular raw materials inside the mixing barrel 2, the first motor 14 starts to run. At this time, the first motor 14 will drive the rotating rod 15 to rotate synchronously, and the rotating rod 15 will drive the stirring rod 16 to rotate synchronously. At this time, the granular raw materials inside the mixing barrel 2 can be stirred and mixed by the stirring rod 16, thereby achieving the purpose of mixing the granular raw materials.

During the rotation of the rotating rod 15, the mounting plate 17 is also driven to rotate synchronously, and the mounting plate 17 drives the connecting sleeve 18 to rotate synchronously, and the connecting sleeve 18 drives the scraper 19 to move synchronously. At this time, the scraper 19 can be used to scrape off the granular raw materials adhered to the inner wall of the mixing barrel 2, thereby preventing the waste of granular raw materials and preventing The granular raw materials affect the mixing effect of other particles. When the scraper 19 needs to be disassembled, replaced or cleaned, it is only necessary to open the closing cover 3 first. At this time, the closing cover 3 will drive the stirring component and the scraping component to move synchronously. When the connecting sleeve 18 is completely separated from the inside of the mixing barrel 2, the plug rod 28 is pressed again. At this time, the plug rod 28 will squeeze the telescopic rod 27 and the return spring 29 synchronously. When the plug rod 28 is separated from the guide groove outside the connecting sleeve 18, the connecting sleeve 18 can be disassembled. The scraper 19 is disassembled to facilitate the staff to replace or clean the scraper 19.
