[0041] In actual operation, when this device is used, polyethylene and additives are added to the heated mixing cylinder 4, and the heating mixing cylinder 4 is heated. The second motor 522 drives the first screw 523 to rotate, causing the first screw 523 to drive the lifting frame 524 to move downwards.

[0042] After the mixing is completed, the first screw 523 is driven to rotate by the second motor 522, which opens the sealing cover 529. Then, the heating mixing cylinder 4 is rotated to the right on the support base 3 by the hydraulic rod 68 in conjunction with the first hinge seat 66 and the second hinge seat 67. At the same time, the third motor 64 drives the second screw 65 to rotate, which drives the sliding seat 63 to slide upward on the mounting frame 62, so that the heating mixing cylinder 4 rotates to discharge material. At the same time, the first mixing roller 513 and the second mixing roller 515 rotate to discharge the polyethylene in the heating mixing cylinder 4, which is then discharged through the discharge hopper 7.
