[0002] A mixer is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials. During the mixing process, it can also increase the contact surface area of ​​the materials to promote chemical reactions and accelerate physical changes.

[0003] After searching, the utility model patent with announcement number CN220589834U discloses a raw material mixer, which includes a filter box, and a feeding mechanism is arranged on the top of the filter box; the utility model arranges a connecting block, a filter screen and a bolt inside the filter box, and by opening the switch door, the connecting block is fixedly connected to the inner sides of the filter box, and the filter screen runs through the inside of the connecting block. By turning the bolts, the filter screen can be better disassembled, replaced and installed, which solves the problem that the filter screen cannot be replaced and may be blocked when filtering liquid raw materials for a long time, thereby reducing the filtering effect. The filter screen can better filter impurities in the liquid raw materials, thereby improving the practicality of the raw material mixer. However, the above patent still has the following shortcomings: the forked stirring rod on the stirring mechanism is only convenient for stirring a specific position in the mixing box, and the stirring efficiency and quality are poor. For this reason, we propose a stirring mechanism for a raw material mixer. Utility Model Content

[0023] Example:

[0024] See also Figure 1-4 A stirring mechanism for a raw material mixer comprises a mixing barrel 1, wherein both ends of the mixing barrel 1 are fixedly connected with support barrels 2, and the ends of the two support barrels 2 are fixedly sleeved with support bearings 3, and rotating columns 4 are fixedly sleeved on the inner sides of the two support bearings 3 and located in the inner cavity of the support barrel 2, and the ends of the two rotating columns 4 are respectively provided with square grooves 5, and a square column 6 is movably sleeved between the two square grooves 5, and the square column 6 passes through the inner cavity of the mixing barrel 1, and a multi-stage electric push rod 7 is fixedly installed on the inner wall of a square groove 5, and the output end of the multi-stage electric push rod 7 is connected to one end of the square column 6, and a servo motor 11 is fixedly installed at the end of a support barrel 2, and the output shaft of the servo motor 11 is connected to the end of a rotating column 4, and a plurality of stirring mechanisms 10 are arranged in the middle of the square column 6, and a scraping mechanism 21 is arranged in the inner cavity of the mixing barrel 1.

[0025] For details, please refer to Figures 2 to 4 The stirring mechanism 10 includes a support box 12 fixedly sleeved on the square column 6, the support box 12 is asymmetrically arranged on the square column 6, two telescopic grooves 13 are opened inside the support box 12, the inner walls of the two telescopic grooves 13 are fixedly connected with springs 14, the ends of the two springs 14 are respectively fixedly connected with moving seats 15, the end surfaces of the two moving seats 15 are respectively fixedly connected with sliding rods 16, one end of the two sliding rods 16 extends to the outside of the support box 12 and is fixedly connected with a stirring shovel 17.

[0026] In this embodiment, the support box 12 is asymmetrically fixed on the square column 6 so that two stirring shovels 17 on a stirring mechanism 10 are asymmetrically arranged in the inner cavity of the mixing barrel 1. The stirring shovel 17 far away from the square column 6 stirs the raw materials far away from the square column 6, and the stirring shovel 17 close to the square column 6 stirs the raw materials close to the square column 6, thereby ensuring the effect of stirring the raw materials.

[0027] For details, please refer to Figure 2 The scraping mechanism 21 includes a turntable 8 rotatably connected to the ends of the inner cavities of the two support tubes 2, a square column 6 and the turntable 8 are movably sleeved, and the sides of the two turntables 8 are fixedly connected with U-shaped scrapers 9, and the end faces and side faces of the U-shaped scrapers 9 are respectively in contact with the inner wall of the mixing barrel 1.

[0028] In this embodiment, two turntables 8 are used to seal the support tube 2 and the mixing barrel 1 to prevent the raw materials in the mixing barrel 1 from entering the support tube 2. In addition, when the square column 6 rotates, the turntable 8 and the U-shaped scraper 9 are driven to rotate synchronously, and the U-shaped scraper 9 is used to scrape the raw materials on the inner wall of the mixing barrel 1 to ensure the quality of raw material mixing.

[0035] Working principle: When in use, first put the required mixed raw materials into the mixing barrel 1 through the feed box 20, then start the servo motor 11 to drive a rotating column 4 to rotate, and drive the square column 6 and another rotating column 4 to rotate synchronously through the rotating column 4, and at the same time use the square column 6 to drive the support box 12, the stirring shovel 17, the turntable 8 and the U-shaped scraper 9 to rotate, use the stirring shovel 17 to stir the raw materials in the inner cavity of the mixing barrel 1, and use the U-shaped scraper 9 to scrape the raw materials off the inner wall of the mixing barrel 1 to ensure the mixing quality, and then start the multi-stage electric push rod 7 to drive the square column 6 to move back and forth horizontally, and use The square column 6 drives the support box 12 and the stirring shovel 17 to move horizontally, thereby changing the horizontal position of the stirring shovel 17 stirring the raw materials, and finally adjusting the speed of the servo motor 11 to drive the square column 6 to rotate. When the speed is low, the centrifugal force on the stirring shovel 17 is small. When the speed of the square column 6 is high, the centrifugal force on the stirring shovel 17 is large. At this time, the stirring shovel 17 will move outward along the axial direction of the support box 12, thereby adjusting the annular rotation position of the stirring shovel 17 on the side of the square column 6, and then changing the position of the stirring shovel 17 stirring the raw materials, to ensure that the raw materials are completely and efficiently mixed.
