[0037] Both ends of the movable rod 506 are fixedly connected to the inner wall of the through groove 505, the end of the stirring shaft 501 away from the inner wall of the through groove 505 is fixedly connected to the centrifugal block 1 507, the scraper 2 508 abuts the surface of the mixing blade 502, the scraper 2 512 abuts the surface of the mixing blade 502, and the end of the elastic rope 513 away from the centrifugal block 2 510 is fixedly connected to the inner wall of the through groove 505.

[0039] The left side of the mixing body 1 is fixedly connected to the discharge box 3, the left side of the discharge box 3 is fixedly installed with a cylinder 301, the output end of the cylinder 301 is connected to a propulsion rod 302, the end of the propulsion rod 302 away from the output end of the cylinder 301 is fixedly connected to a connecting frame 303, the right side of the connecting frame 303 is fixedly connected to a discharge baffle 304, the top of the connecting frame 303 is fixedly connected to a slide rod 305, the top of the discharge box 3 is fixedly installed with a slide rail 306, the two ends of the slide rod 305 are connected to rollers 307, the outer surface of the roller 307 is aligned with the slide rail 306, and the outer surface of the roller 307 is aligned with the outer surface of the slide rail 306. 6 is slidably connected to the inner wall of the mixing body 1, a discharge port 8 is opened on the left side of the mixing body 1, and the discharge baffle 304 is adapted to the shape of the discharge port 8. A discharge pipe 4 connected to the inside of the discharge box 3 is fixedly installed at the bottom of the discharge box 3. Before mixing the main material and the auxiliary material, the propulsion rod 302 is pushed by starting the cylinder 301, and the propulsion rod 302 pushes the connecting frame 303. The connecting frame 303 drives the sliding rod 305 and the roller 307 on its top to slide on the inner wall of the slide rail 306, thereby pushing the discharge baffle 304 close to the discharge port 8, sealing and blocking the discharge port 8;

[0040] After the main material and auxiliary material of the paracetamol and yellow pheniramine granules are mixed, the cylinder 301 is started, and the cylinder 301 pulls the push rod 302, and the push rod 302 drives the connecting frame 303 to move to the left, thereby driving the slide rod 305 and the roller 307 to slide in the opposite direction on the inner wall of the slide rail 306, pushing the discharge baffle 304 away from the discharge port 8.

[0041] Working principle: When the main ingredient and auxiliary ingredient of the paracetamol and yellow pheniramine granules are mixed, the main ingredient and auxiliary ingredient are poured into the inner tank body 5, and then the motor 7 is started. The output shaft of the motor 7 drives the stirring shaft 501 to rotate, and the stirring shaft 501 drives the stirring blade 502 to rotate to stir and mix the main ingredient and auxiliary ingredient. During the mixing process, the stirring blade 502 generates centrifugal force due to the continuous rotation. Under the action of the centrifugal force, the centrifugal block 1 507 and the centrifugal block 2 510 slide on the surface of the movable rod 506. The centrifugal block 1 507 continuously squeezes the spring 509 under the action of the centrifugal force. When the spring 509 is squeezed to the maximum After a large amount of compression, under the action of the restoring force of the spring 509 itself, the centrifugal block 1 507 will be pushed to slide on the surface of the movable rod 506 toward the side close to the stirring shaft 501. Under the subsequent centrifugal force and the restoring force of the spring 509 itself, the centrifugal block 1 507 will slide back and forth within a certain range. During the reciprocating sliding process of the centrifugal block 1 507, the scraper 2 508 will be driven to continuously scrape the surface of the stirring blade 502, thereby scraping off the main material and auxiliary material attached to the surface of the stirring blade 502, preventing the main material and auxiliary material from adhering to the stirring blade 502 and affecting subsequent mixing, thereby reducing the mixing efficiency.

[0042] Under the action of centrifugal force, the centrifugal block 2 510 will slide on the surface of the movable rod 506 to the side away from the stirring shaft 501. When the centrifugal block 2 510 slides, it will drive the connecting plate 511 and the scraper 2 512 to scrape the surface of the stirring blade 502. In the scraping process, the main material and auxiliary material attached to the surface of the stirring blade 502 will be scraped off, preventing the main material and auxiliary material from adhering to the stirring blade 502 and affecting the subsequent mixing, thereby reducing the mixing efficiency. When the centrifugal block 2 510 is pushed by the centrifugal force to slide away from the stirring shaft 501, it will pull the elastic rope 513. When the elastic rope 513 is pulled to the maximum extension, The centrifugal block 510 will be pulled back under the action of the restoring force of the elastic rope 513 itself, and slide on the surface of the movable rod 506 toward the side close to the stirring shaft 501. Under the continuous action of the subsequent centrifugal force and the restoring force of the elastic rope 513 itself, the centrifugal block 510 will make a reciprocating motion within a certain range and for a certain period of time, thereby driving the connecting plate 511 and the scraper 512 to continuously scrape the surface of the stirring blade 502 back and forth, thereby scraping off the main material and auxiliary material attached to the surface of the stirring blade 502, preventing the main material and auxiliary material from adhering to the stirring blade 502 and affecting the subsequent mixing, thereby reducing the mixing efficiency.
