[0023] The discharge pipe 8 and the spoon-shaped baffle 302 are located in the same vertical plane, and the discharge pipe 8 is directly above the spoon-shaped baffle 302 in one of the horizontal states. When the raw material is discharged downward from the discharge pipe 8, the impact force generated on the spoon-shaped baffle 302 is used to make the spoon-shaped baffle 302 rotate with the rotating shaft 301.

[0024] The mounting frame 1 is provided with a cleaning assembly 19 , and the discharge of the mixing kettle 12 is used to provide a driving force for the cleaning assembly 19 to move downward.

[0025] like Figure 1-Figure 6 and Figure 8 As shown, the cleaning assembly 19 includes a slide 1901, a slide plate 1902, a spring fixing plate 1903, a spring 1904, a baffle connecting rod 1905, a baffle plate 1906, a U-shaped connecting frame 1907 and a scraper 1908; The mounting frame 1 is provided with symmetrical sliding grooves 1901 on both sides thereof, a slide plate 1902 is slidably mounted on the sliding groove 1901, a spring fixing plate 1903 is fixedly mounted on the mounting frame 1, the slide plate 1902 and the spring fixing plate 1903 are connected by a spring 1904, a baffle connecting rod 1905 is mounted on the bottom of the slide plate 1902, a baffle plate 1906 is mounted on the baffle connecting rod 1905, the baffle plate 1906 is located directly below the discharge port 13 of the mixing kettle 12, a U-shaped connecting frame 1907 is mounted above the slide plate 1902, a scraper 1908 is mounted on the U-shaped connecting frame 1907, and the outer wall of the scraper 1908 It contacts the inner wall of the mixing kettle 12. When the mixing is completed, the material is discharged downward from the discharge port 13. The baffle plate 1906 is used to generate an impact force, so that the baffle plate 1906 drives the slide plate 1902 to move downward through the baffle connecting rod 1905. At the same time, the U-shaped connecting frame 1907 drives the scraper 1908 to move downward along the inner wall of the mixing kettle 12, and the material stuck on the inner wall of the mixing kettle 12 is scraped downward and discharged. The residue on the inner wall of the mixing kettle after discharge can be scraped and discharged, which not only avoids the waste of material, but also cleans the inside of the mixing kettle. The upper surface of the scraper 1908 is conical, which ensures that no raw materials are accumulated on the scraper 1908 during feeding.

[0026] The cleaning assembly 19 also includes an outer gear 1909, a rotating ring 1910, an arc-shaped connecting rod 1911, a moving stopper 1912, a fixing column 1913, a second mounting plate 1914, a transmission gear 1915 and a driving motor 1916; An annular mounting groove is provided at the inner diameter of the scraper 1908, and the cross-section of the annular mounting groove is a C-shaped opening, an external gear 1909 is fixedly installed in the annular mounting groove, a swivel 1910 is rotatably installed in the external gear 1909, a plurality of fixed columns 1913 are fixedly installed in the annular mounting groove, a plurality of movable baffles 1912 are rotatably installed on the plurality of fixed columns 1913, the plurality of movable baffles 1912 are connected to the swivel 1910 through an arc-shaped connecting rod 1911, the two ends of the arc-shaped connecting rod 1911 are hinged to the movable baffle 1912 and the swivel 1910 respectively, a second mounting plate 1914 is installed on the swivel 1910, a driving motor 1916 is installed on the second mounting plate 1914, a transmission gear 1915 is installed on the output shaft of the driving motor 1916, and the transmission gear 1915 is meshed with the external gear 1909.

[0027] The drive motor 1916 is electrically connected to the electric telescopic rod 6. When the electric telescopic rod 6 controls the agitator 11 to extend into the mixing kettle 12, the drive motor 1916 controls the multiple movable baffles 1912 to retract. When the electric telescopic rod 6 is extended, the drive motor 1916 controls the multiple movable baffles 1912 to form a shutter. The outer wall of the scraper 1908 contacts the inner wall of the mixing kettle 12. In the initial state, the electric telescopic rod 6 is in a retracted state, the agitator 11 extends into the mixing kettle 12, the movable baffles 1912 retract, and the bottom of the scraper 1908 is open. When the stirring is finished, the electric telescopic rod 6 is in a retracted state. The electric telescopic rod 6 extends, driving the agitator 11 to move upward. After the extension is completed, the electric telescopic rod 6 controls the driving motor 1916 to rotate forward, driving the gear 1915 to move clockwise along the outer gear 1909, and at the same time driving the transmission swivel 1910 to rotate synchronously. When rotating, the swivel 1910 can drive the movable baffle 1912 to rotate toward the center of the circle through the arc-shaped connecting rod 1911, thereby closing the opening of the scraper 1908, so as to facilitate the scraping of the material stuck to the inner wall of the mixing kettle 12 when the scraper 1908 moves downward, and exert a downward squeezing force on the material to accelerate the discharge of the material.

[0028] A connecting column 20 is installed below the discharge baffle 14, and an arc scraper 21 is installed on the connecting column 20. The curvature of the arc scraper 21 is the same as that of the baffle 1906. In the initial state, the lower surface of the arc scraper 21 is in contact with the upper surface of the baffle 1906. When the discharge baffle 14 moves, the arc scraper 21 is driven to move synchronously through the connecting column 20, so that the material remaining on the baffle 1906 during the discharge process can be cleaned.

[0029] Working principle of the present invention: When it is necessary to mix the materials, start the feed pump 2, and discharge the raw materials into the mixing kettle 12 through the feed pipe 7 and the discharge pipe 8. The raw liquid can flow into the mixing kettle 12 through the liquid feeding component 3. At the same time, start the first motor 10, and the first motor 10 drives the agitator 11 to rotate to mix the materials in the mixing kettle 12. After the mixing is completed, start the second motor 16 to drive the discharge screw 17 to rotate. At this time, the discharge slider 18 will move, and drive the discharge baffle 14 to move at the discharge port 13 through the connecting rod 15, so that the material flows out from the discharge port 13, thereby realizing the control of the discharge amount.

[0030] When the raw material is discharged downward from the discharge pipe 8, the impact force is generated on the spoon-shaped baffle 302, so that the spoon-shaped baffle 302 rotates with the rotating shaft 301. The rotating shaft 301 can drive the reciprocating screw 307 to rotate through the first pulley 303, the belt 309 and the second pulley 308, thereby causing the reciprocating slider 310 to reciprocate along the reciprocating screw 307. During the movement, the reciprocating slider 310 can drive the piston plate 312 to move synchronously through the hollow connecting rod 311, so as to realize the reciprocating movement of the piston plate 312 in the working box 305. When the reciprocating slider 310 drives the piston plate 312 to move toward the side of the first mounting plate 306, the excess part of the reciprocating screw 307 can extend into the hollow connecting rod 3 11, when the piston plate 312 moves to the side away from the reciprocating screw 307, the raw liquid in the first working chamber 313 is squeezed and discharged from the first liquid outlet pipe 317, and the second working chamber 314 sucks the raw liquid through the second liquid inlet pipe 316. When the piston plate 312 moves to the side close to the reciprocating screw 307, the raw liquid in the second working chamber 314 is squeezed and discharged from the second liquid outlet pipe 318, and the first working chamber 313 sucks the raw liquid through the first liquid inlet pipe. The discharged raw liquid flows to the mixing kettle 12 through the manifold 319, so that the raw liquid can enter synchronously and continuously with the raw material, avoiding the poor wetting effect and long uniform mixing time caused by the batch entry of the raw material and the raw liquid.

[0031] When the mixing is completed, the material is discharged downward from the discharge port 13, and the baffle plate 1906 is used to generate an impact force, so that the baffle plate 1906 drives the slide plate 1902 to move downward through the baffle connecting rod 1905. At the same time, the U-shaped connecting frame 1907 drives the scraper 1908 to move downward along the inner wall of the mixing kettle 12, and the material adhering to the inner wall of the mixing kettle 12 is scraped downward and discharged. The residue on the inner wall of the mixing kettle after discharge can be scraped and discharged, which not only avoids the waste of material, but also cleans the inside of the mixing kettle. The upper surface of the scraper 1908 is conical, which ensures that no raw materials are accumulated on the scraper 1908 during feeding.

[0032] In the initial state, the electric telescopic rod 6 is in a retracted state, the agitator 11 is extended into the mixing kettle 12, the movable baffle 1912 is retracted, and the bottom of the scraper 1908 is open. When the stirring is completed, the electric telescopic rod 6 is extended to drive the agitator 11 to move upward. After the extension is completed, the electric telescopic rod 6 controls the drive motor 1916 to rotate forward, driving the gear 1915 to move clockwise along the outer gear 1909, and at the same time drives the transmission swivel 1910 to rotate synchronously. When rotating, the swivel 1910 can drive the movable baffle 1912 to rotate toward the center of the circle through the arc-shaped connecting rod 1911, thereby closing the opening of the scraper 1908, so as to facilitate the scraping of the material stuck to the inner wall of the mixing kettle 12 when the scraper 1908 moves downward, and exert a downward squeezing force on the material to accelerate the discharge of the material.
