[0025] By setting up the stirring structure 5, the motor 51 drives the transmission shaft 53 to rotate, and then drives the bracket 54 to rotate. The bracket 54 drives the spiral roller 59 to rotate, and the spiral roller 59 is inserted into the discharge pipe 510, thereby realizing stable and uniform feeding of the plastic additive. The stirring rod 56 rotates inside the storage box 2, which can fully disperse and mix different regulators, thereby improving the use quality of the plastic additive.

[0027] By providing the stirring rod 56 , the motor 51 drives the transmission shaft 53 to rotate, thereby driving the bracket 54 to rotate, and the bracket 54 drives the stirring rod 56 to rotate. The stirring rod 56 rotates to mix different additives evenly.

[0028] like Figure 3 As shown, a gear ring 57 is fixedly connected to the edge of the top of the inner cavity of the storage box 2, and the inner wall of the gear ring 57 is meshed with the outer walls of the four planetary gears 55.

[0029] By setting the gear ring 57 and the arc rod 58, the planetary gear 55 rotates around the inner wall of the storage box 2 under the action of the bracket 54, and rotates on its own under the action of the gear ring 57, thereby driving the stirring rod 56 to rotate, thereby further improving the stirring quality. The rotation of the arc rod 58 can draw the material at the bottom of the storage box 2 to the discharge pipe 510, thereby reducing problems such as material accumulation at the bottom of the storage box 2.

[0033] By setting the dredging rod 65, the motor 51 drives the transmission shaft 53 to rotate, thereby driving the first bevel gear 61 to rotate, thereby driving the two second bevel gears 62 to rotate, and then driving the two eccentric wheels 63 to rotate.

In this process, the bracket 54 drives the stirring rod 56 to rotate, and the stirring rod 56 rotates to mix different additives evenly. At the same time, the planetary gear 55 rotates around the inner wall of the storage box 2 under the action of the bracket 54, and rotates under the action of the gear ring 57, thereby driving the stirring rod 56 to rotate, thereby further improving the stirring quality. When the spiral roller 59 rotates to discharge the material, the bracket 54 drives the arc The rod 58 rotates, and the arc rod 58 rotates to gather the material at the bottom of the storage box 2 toward the discharge pipe 510, thereby reducing problems such as additive residue. When the first feeding pipe 3 and the second feeding pipe 4 are loading, the motor 51 drives the transmission shaft 53 to rotate, thereby driving the first bevel gear 61 to rotate, thereby driving the two second bevel gears 62 to rotate, and then driving the two eccentric wheels 63 to rotate. The two eccentric wheels 63 rotate to squeeze the dredging rod 65 to rotate upward, thereby dredging the plastic additives. While the dredging rod 65 rotates upward, the rectangular plate 66 rotates downward, thereby squeezing the round rod 69 to slide downward, thereby compressing the elastic telescopic rod 67. When the eccentric wheel 63 rotates downward, the elastic telescopic rod 67 pushes the round rod 69, thereby pushing the rectangular rod to slide upward, causing the dredging rod 65 to rotate downward.
