The utility model is a mixing device for the production of engineering plastics, wherein a discharge motor drives the closed ring plate to flip, and the weighed raw materials are discharged, which can realize quantitative discharge and improve the convenience of discharge. The driving motor drives the rotating rod to rotate through the flange, and at the same time drives the linkage sleeve to rotate through the card strip and the card slot, drives the stirring rod to rotate, effectively stirs the raw materials, and improves the mixing efficiency.

The up and down sliding of the slider 503 changes the height of the centrifugal fairing 507 and the bottom stirring blade 508, so that the stirring of the engineering plastic is more sufficient and complete.

[0023] Furthermore, the working step 1 and the storage tank 2 are fixedly connected, the storage tank 2 and the tank cover 3 are rotatably connected, the inner diameter of the storage tank 2 is tightly fitted with the outer diameter of the tank cover 3, and the storage tank 2 and the discharge port 4 are fixedly connected. The working step 1 provides a higher working height for industrial personnel, ensuring real-time manual operation and close visual monitoring of the mixing process. The arrangement of the storage tank 2 and the tank cover 3 can ensure that the mixing environment is completely closed, avoiding waste caused by spillage of engineering plastics during the mixing process.

[0024] Furthermore, the working step 1 and the support hanger 501 are welded, the support hanger 501 and the slide bar 502 are connected by a slot, two groups of slide bars 502 are provided, and the slide bar 502 and the slider 503 are slidably connected. The slider 503 can move up and down, and the slider 503 slides vertically on the slide bar 502, which can change the up and down movement of other mixing components of the mixing mechanism 5 and increase the degree of stirring of the engineering plastic.

[0025] Furthermore, the slider 503 is connected to the stirring motor 504 by bolts, and the stirring motor 504 is slidably connected to the sealing ring 505. The inner diameter of the tank cover 3 matches the outer diameter of the sealing ring 505. In the initial stage, the engineering plastic can be continuously loaded into the hopper 506 through the central opening of the tank cover 3. After the engineering plastic is loaded, the sealing ring 505 can be slid to the central opening of the tank cover 3. The sealing ring 505 can ensure that the mixing environment is completely closed, avoiding waste caused by spillage of engineering plastic during the mixing process.

[0026] Furthermore, the stirring motor 504 and the hopper 506 are fixedly connected. The stirring motor 504 passes through the hopper 506 and is fixedly connected to the centrifugal fairing 507. The diameter of the hopper 506 is larger than the centrifugal fairing 507. The top of the hopper 506 fits tightly with the bottom of the closed tank cover 3. The engineering plastic falls from the central opening of the tank cover 3 into the hopper 506, and then falls from the central opening at the bottom of the hopper 506 to the centrifugal fairing 507. The centrifugal fairing 507 is driven by the stirring motor 504 to rotate horizontally at high speed, and the engineering plastic is centrifugally thrown out at high speed from the horizontal slot of the centrifugal fairing 507, thereby achieving preliminary and sufficient mixing of different engineering plastics.

[0027] Furthermore, the stirring motor 504 and the stirring blade 508 are welded, the slider 503 and the lifting gear 509 are rotationally connected, the lifting gear 509 and the lifting motor 510 are fixedly connected, the lifting gear 509 and the rack 511 are meshed, and the lifting gear 509 and the rack 511 fit tightly together. The rotation of the stirring motor 504 drives the stirring blade 508 at the bottom end to rotate at high speed, stirring the engineering plastic in the storage tank 2 for the second time. The rotation of the lifting motor 510 drives the lifting gear 509 to rotate, and the rotating lifting gear 509 moves on the rack 511, driving the slider 503 to move up and down at the slide bar 502. The up and down sliding of the slider 503 changes the height of the centrifugal fairing 507 and the bottom stirring blade 508, so that the stirring of the engineering plastic is more sufficient and complete.

[0028] Working principle: First, the industrial personnel enter the working step 1, manually open the tank cover 3 to check whether there is any residual material or residue in the storage tank 2, start the stirring motor 504 to drive the other parts of the mixing mechanism 5 at the bottom to rotate, and pour different engineering plastics from the central opening of the tank cover 3. For continuous filling of engineering plastics, the inclined slope in the engineering plastic hopper 506 rolls down from the bottom opening to the centrifugal fairing 507. The centrifugal fairing 507 is driven by the stirring motor 504 to rotate horizontally at high speed, and the engineering plastic is centrifugally thrown out at high speed from the horizontal slot of the centrifugal fairing 507 to achieve preliminary and sufficient mixing of different engineering plastics. The engineering plastic thrown out by centrifugation falls and splashes into the storage tank 2 at the bottom. The rotation of the stirring motor 504 drives the stirring blade 508 at the end of the bottom to rotate at high speed, The engineering plastic is stirred for the second time. After the engineering plastic is filled, the sealing ring 505 on the stirring motor 504 can be slid downward, and the sealing ring 505 is tightly covered with the tank cover 3 to ensure that the mixing environment is fully closed. Then, the lifting motor 510 is started at the same time, and the lifting motor 510 rotates to drive the lifting gear 509 to rotate. The rotating lifting gear 509 moves on the rack 511, driving the slider 503 to move up and down at the slide bar 502. The up and down sliding of the slider 503 changes the height of the centrifugal fairing 507 and the bottom stirring blade 508. The high-speed rotating stirring blade 508 moves up and down at the same time, making the stirring of the engineering plastic more sufficient and complete. The mixed engineering plastic can be discharged from the discharge port 4 at the bottom of the storage tank 2, thus completing the use process of a mixing device for engineering plastic production.
