In this way, the flowing mixed material at the edge of the inner wall of the mixing tank 101 can be fully mixed, which can greatly improve the mixing efficiency and mixing effect of the materials in the mixing tank 101.

[0035] In this embodiment of the present invention, a reinforcing plate 305 is fixedly provided on the side of the hollow mixing barrel 301, and one side of the reinforcing plate 305 is fixedly installed on the side of the mixing tank 101. A guide channel 306 extending obliquely downward is fixedly provided on the side of the hollow mixing barrel 301. The second reflux port 303 is connected to the inner cavity of the guide channel 306. The guide channel 306 is plugged into the corresponding fourth reflux port 105, and the lower end of the guide channel 306 extends to a position close to the axis of the mixing tank 101. Through this structural design, during the upward movement of the first plugging disk 304, the flowing mixed material in the hollow mixing barrel 301 can be pushed upward by the upwardly moving first plugging disk 304, so that the upstream The flowing mixture flows into the guide channel 306 along the second reflux port 303 and the fourth reflux port 105, and then flows downward from each guide channel 306 back to the center of the mixing tank 101.

[0036] In this embodiment of the present invention, a hollow auxiliary cylinder 307 connected to the hollow mixing cylinder 301 is fixedly provided at the bottom thereof, and the inner diameter of the hollow auxiliary cylinder 307 is the same as the inner diameter of the hollow mixing cylinder 301. The second flow-pushing disk 501 is slidably arranged inside the hollow auxiliary cylinder 307. A vertical limiting rod 308 is fixedly arranged at the bottom of the hollow auxiliary cylinder 307. The top of the vertical limiting rod 308 is fixedly arranged on the top of the hollow mixing cylinder 301. The first flow-pushing disk 304 and the second flow-pushing disk 501 are both slidably sleeved on the vertical limiting rod 308. A mixing power rod 309 is rotatably arranged inside the hollow mixing cylinder 301. A mixing gear 310 is fixedly installed on the upper end of the mixing power rod 309. 09 The lower end portion passes through the hollow auxiliary cylinder 307, and a reciprocating spiral groove is opened on the side surface of the mixing power rod 309. The limiting portion fixed on the inner wall of the first plug flow disk 304 slides and fits inside the corresponding reciprocating spiral groove. When the mixing power rod 309 is controlled to rotate, the first plug flow disk 304 can be driven to slide up and down along the inside of the hollow mixing cylinder 301 through the cooperation of the reciprocating spiral groove and the limiting portion. In the initial state, the first plug flow disk 304 is close to the bottom of the first reflux port 302. When the mixing power rod 309 is controlled to rotate so that the first plug flow disk 304 moves upward until the mixing power rod 309 stops rotating, the first plug flow disk 304 is close to the bottom of the second reflux port 303 at this time.

[0037] In this embodiment of the present invention, the guide bearing assembly 4 includes a guide bearing frame 401, one side of the guide bearing frame 401 is fixedly arranged on the inner wall of the annular base 102, and the other side of the guide bearing frame 401 is fixedly arranged on the outer wall of the fixed frame 103. A vertical guide rod 402 and a transmission sleeve 403 are respectively arranged on the inner side of the guide bearing frame 401, and the vertical guide rod 402 is fixedly connected to the guide bearing frame 401, and the transmission sleeve 403 is rotatably connected to the guide bearing frame 401. A reciprocating spiral groove (similar to a reciprocating screw rod structure) is provided on the side, and a linkage groove is provided on the inner wall of the transmission sleeve 403. The mixing power rod 309 is plugged into the transmission sleeve 403, and the linkage convex strips fixed on the side of the mixing power rod 309 are matched with the corresponding linkage groove gap; when the mixing power rod 309 is controlled to rotate to drive the first flow-pushing plate 304 to move upward, the transmission sleeve 403 that rotates synchronously with the mixing power rod 309 drives the entire reflux support assembly 5 to move downward, and the mixing power rod 309 is rotated synchronously with the mixing power rod 309. As the first plug flow plate 304 moves upward, the second plug flow plate 501 moves downward along the hollow auxiliary cylinder 307. When the first plug flow plate 304 moves upward to be close to the bottom of the second reflux port 303, the second plug flow plate 501 just fits the bottom of the hollow auxiliary cylinder 307. When the mixing power rod 309 continues to rotate, the first plug flow plate 304 can be driven to move downward. In this process, the transmission sleeve 403 that rotates synchronously with the mixing power rod 309 drives the entire reflux support assembly 5 to move upward. In this process, the flowing mixed material in the hollow mixing cylinder 301 is pushed out and refluxed into the mixing tank 101 through the joint action of the first plug flow disk 304 and the second plug flow disk 501. When the mixing power rod 309 stops rotating again, the first plug flow disk 304 returns to the initial position (i.e., the top of the first plug flow disk 304 is close to the bottom of the first reflux port 302), and the second plug flow disk 501 also moves up and returns to the initial position (i.e., the second plug flow disk 501 is attached to the bottom of the first plug flow disk 304).

[0038] In this embodiment of the present invention, the reflux support assembly 5 also includes a support frame 502 sleeved on the transmission sleeve 403, a lifting control ring 503 slidably matched on the transmission sleeve 403 is fixedly provided at the bottom of the support frame 502, a limit portion fixed on the inner wall of the lifting control ring 503 is slidably matched inside the corresponding reciprocating spiral groove, an extension seat 504 slidably sleeved on the vertical guide rod 402 is fixedly provided on the circumferential side of the lifting control ring 503, a support sleeve 505 slidably sleeved on the mixing power rod 309 is fixedly provided on the top of the support frame 502, the support sleeve 505 is slidably matched with the hollow auxiliary cylinder 307, and the second plug flow plate 501 is fixedly installed on the top of the support sleeve 505; when the mixing power rod 309 is controlled to rotate so that the first plug flow plate 304 moves upward along the hollow mixing cylinder 301, the hollow mixing cylinder 301 can be moved upward by the first plug flow plate 304 The flowing mixed material in the barrel 301 is pushed upward, so that the flowing mixed material in the upstream flows into the guide channel 306 along the second reflux port 303 and the fourth reflux port 105, and then flows downward from each guide channel 306 back to the center position of the mixing tank 101. During the upward movement of the first plug flow disk 304, the flowing mixed material in the mixing tank 101 flows into the hollow mixing barrel 301 again. When the mixing power rod 309 is controlled to continue to rotate so that the first plug flow disk 304 moves downward along the hollow mixing barrel 301, the flowing mixed material in the hollow mixing barrel 301 can be pushed again by the downwardly moved first plug flow disk 304, so that the flowing mixed material in the hollow mixing barrel 301 flows back into the mixing tank 101 along the first reflux port 302 and the third reflux port 104 again, thereby achieving sufficient mixing between the flowing mixed materials at the edge and the center of the mixing tank 101.

[0040] In this embodiment of the present invention, a material storage box 606 is fixedly installed on the top of the support platform 603, and a material guide protective cover 607 connected to the material storage box 606 is fixedly installed on the support platform 603. A discharge port 608 is opened inside the material guide protective cover 607, and an inclined guide plate 609 extending to the discharge port 608 is fixedly set inside the material storage box 606. A discharge port 610 matched with the inclined guide plate 609 is opened on one side of the material storage box 606. In the process of controlling the rotation of the mixing power shaft 602, the powder material in the material storage box 606 slides down along the inclined guide plate 609, passes through the discharge port 610 and enters the material guide protective cover 607, and gradually falls along the discharge port 608 into the mixing tank 101 to achieve mixing and stirring; a plurality of arc-shaped mixing parts 611 are fixedly installed on the side surface of the mixing power shaft 602, and a limited position slide is opened at the bottom of the guide channel 306. A radial mixing plate 311 is slidably arranged inside the slideway, and an elastic element 312 is fixedly installed on one side of the radial mixing plate 311, and one end of the elastic element 312 is fixedly arranged on the inner wall of the mixing tank 101. The arc-shaped mixing portion 611 is used to push the radial mixing plate 311 to move radially. When the arc-shaped mixing portion 611 is driven by the mixing power shaft 602 to rotate to achieve mixing and stirring, the rotating arc-shaped mixing portion 611 squeezes and pushes the radial mixing plate 311 to move and compresses the elastic element 312. When the arc-shaped mixing portion 611 crosses the corresponding radial mixing plate 311, the strong restoring force of the elastic element 312 can be used to make the radial mixing plate 311 move in the opposite direction and reset. In this way, the radial mixed flow stirring of the flowing mixture at the edge of the mixing tank 101 can be achieved through the synchronous radial movement of each radial mixing plate 311, which can greatly improve the mixing effect of the material in the mixing tank 101.
