[0026] Specifically, a mixing tank 2 is installed above the base 1, a top plate 21 is installed on the top of the mixing tank 2, a partition plate 3 is installed above the mixing tank 2, and multiple fixing columns 31 are installed on the bottom surface of the partition plate 3. The other end of the fixing column 31 is fixed to the outer side of the top surface of the mixing tank 2. Different plastic masterbatches are premixed through the mixing tank 2. The partition plate 3 and the mixing tank 2 are connected by the fixing columns 31. An auger shaft 53 is installed inside the mixing tank 2. The auger shaft 53 is coaxially arranged with the mixing tank 2. The top end of the auger shaft 53 passes through the top plate 21 and the partition plate 3. The top surface of the auger shaft 53 is flush with the top surface of the partition plate 3. An auger plate 54 is installed on the outer side of the auger shaft 53. The rotation of the auger shaft 53 drives the rotation of the auger plate 54, which in turn drives the plastic masterbatches inside the mixing tank 2 to move. During the movement of the masterbatches, they are mixed evenly.

[0027] A connecting seat 52 is coaxially arranged at the top end of the auger shaft 53. A drive shaft 51 is coaxially arranged on the top surface of the connecting seat 52. A rotary motor 5 is coaxially arranged at the top end of the drive shaft 51. The connecting seat 52 is frustoconical. The bottom end of the connecting seat 52 is in contact with the top surface of the auger shaft 53, and the top end of the connecting seat 52 is in contact with the drive shaft 51. The size of the auger shaft 53 is larger than the size of the drive shaft 51.

[0028] Specifically, the drive shaft 51 is driven to rotate by the rotary motor 5, which in turn drives the connecting seat 52 to rotate, and then drives the auger shaft 53 to rotate, so that the auger plate 54 rotates inside the mixing tank 2. The drive shaft 51 and the auger shaft 53 are connected by the connecting seat 52, so that the drive shaft 51 can drive the auger shaft 53 to rotate more evenly.

[0029] A second bearing 55 is provided at the connection between the auger shaft 53 and the top plate 21, and a first bearing 32 is provided at the connection between the auger shaft 53 and the partition plate 3.

[0030] Specifically, the auger shaft 53 can rotate independently of the mixing tank 2 via the second bearing 55, and the auger shaft 53 can rotate independently of the partition plate 3 via the first bearing 32.

[0031] A feed pipe 43 is provided on the top surface of the top plate 21. The bottom surface of the feed pipe 43 is flush with the bottom end of the top plate 21.

The size of the feeding port 4 is larger than the size of the first guide pipe 41, thereby reducing the difficulty of adding. A buffer pipe 42 is connected between the first guide pipe 41 and the feed pipe 43 to prevent the masterbatch from entering the mixing tank 2 too quickly, thereby improving the mixing effect of the auger plate 54. By setting multiple feeding ports 4, various different masterbatches can be simultaneously added into the mixing tank 2, further improving the mixing effect of the auger plate 54.

[0033] A discharge port 23 is provided at the center of the bottom surface of the mixing tank 2, and the discharge port 23 penetrates the bottom surface of the mixing tank 2. A chute 22 is provided inside the bottom surface of the mixing tank 2, and the center of the chute 22 coincides with the center of the discharge port 23. A pair of opening and closing plates 24 are symmetrically arranged inside the chute 22. The pair of opening and closing plates 24 are circular in shape, and the center of the circle formed by the pair of opening and closing plates 24 coincides with the center of the discharge port 23. The total diameter of the pair of opening and closing plates 24 is larger than the diameter of the discharge port 23.

[0034] Specifically, the mixing tank 2 is connected to the outside through the discharge port 23, and the mixed masterbatch in the mixing tank 2 is discharged. The opening and closing of the discharge port 23 is achieved by the movement of the opening and closing plate 24 inside the chute 22.

[0035] A connecting plate 14 is provided on one side of the bottom surface of the opening and closing plate 24. A telescopic rod 13 is provided at the center of the two connecting plates 14 facing each other. A telescopic seat 12 is coaxially provided at the other end of the telescopic rod 13.

[0036] Specifically, the telescopic seat 12 is driven by the drive motor 11 to move the telescopic rod 13, which in turn drives the connecting plate 14 to move synchronously. The opening and closing plate 24 is moved by the connecting plate 14 to realize the opening and closing of the discharge port 23. After the two opening and closing plates 24 are put together, the end faces of the two connecting plates 14 are also put together.

[0037] A feeding port 16 is provided on the base 1, which passes through the base 1. The center of the feeding port 16 coincides with that of the discharge port 23.

[0038] Specifically, the support rod 15 and the drive motor 11 jointly provide support for the mixing tank 2, and the masterbatch in the mixing tank 2 enters the next process after the discharge port 23 is opened through the feed port 16.

[0039] During use, various masterbatches are added into the mixing tank 2 through multiple feeding ports 4. The rotary motor 5 drives the auger shaft 53 to rotate inside the mixing tank 2, which in turn drives the auger plate 54 to rotate, causing the masterbatches inside the mixing tank 2 to move up and down repeatedly, so as to achieve premixing of various different masterbatches. After a certain period of premixing, the rotary motor 5 stops working, causing the masterbatches in the mixing tank 2 to fall back to the bottom of the mixing tank 2. The drive motor 11 is controlled to drive the connecting plate 14 to move, which in turn moves the opening and closing plate 24, causing the discharge port 23 to open and discharge the masterbatches inside the mixing tank 2, which then enter the next process through the feeding port 16.
