Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1-2 , in the embodiment proposed in this application: A mixing device for plastic particle processing, including a cylinder body 1, a support frame 11 is fixedly arranged on the side wall of the cylinder body 1, a first discharge port 12 is opened at the bottom of the cylinder body 1, a plurality of feed ports 13 are evenly opened at the top of the cylinder body 1, a material receiving hopper 2 is arranged inside the cylinder body 1, a second discharge port 21 is arranged below the material receiving hopper 2, a first support 3 is transversely arranged inside the cylinder body 1 corresponding to the second discharge port 21, the first support 3 is fixed on the inner side wall of the cylinder body 1, and the outer side wall of the second discharge port 21 is rotatably inserted on the first support 3. A driving structure 4 for driving its rotation is arranged outside the cylinder body 1 corresponding to the material receiving hopper 2, and a stirring structure 5 is arranged below the first support 3. The bottom of the stirring structure 5 can be rotatably inserted into the first discharge port 12;

[0020] By driving the rotation of the material receiving hopper through the driving structure 4, preliminary mixing of various plastic particles can be carried out during feeding, and then full stirring and mixing are carried out through the stirring structure 5, improving the mixing effect and ensuring the quality and color of the produced plastic products.

[0021] In another embodiment, please refer to Figure 1-2 , the driving structure 4 includes a driving motor 41, the driving motor 41 is fixedly arranged on the outer right side wall of the cylinder body 1, a gear 42 is fixedly arranged at the driving end of the driving motor 41, an opening 14 is opened on the right side wall of the cylinder body 1 corresponding to the gear 42, teeth 43 are arranged on the outer side wall of the material receiving hopper 2 corresponding to the opening, and the teeth 43 extend out of the opening 14 and mesh with the gear 42;

[0022] By starting the rotation of the drive motor 41, the gear 42 at the drive end is driven to rotate, thereby driving the receiving hopper 2 provided with teeth 43 to rotate on the first bracket 3. Since the position of the feed port 13 remains unchanged during feeding, various plastic particles falling from the feed port 13 can be evenly distributed in the receiving hopper 2 during the rotation of the receiving hopper 2, achieving a preliminary mixing effect.

[0023] In another embodiment, please refer to Figure 1-2 , the stirring structure 5 includes a hydraulic cylinder 51 with a piston rod vertically downward. A fixing block 52 is provided at the lower side of the first bracket 3 corresponding to the hydraulic cylinder 51. At the edge of the upper side of the fixing block 52, it is fixedly connected to the bottom of the first bracket 3 through a connecting rod 53. The hydraulic cylinder 51 is fixedly connected to the bottom of the fixing block 52. A stirring assembly 6 is fixedly provided at the bottom of the piston rod of the hydraulic cylinder 51. A conical block 54 is provided on the upper side of the fixing block 52 corresponding to the second discharge port 21, facilitating the smooth fall of plastic particles into the bottom of the cylinder 1.

[0024] In this embodiment, the stirring assembly 6 includes a rotating motor 61 with a drive end at the bottom. The rotating motor 61 is fixedly provided at the bottom of the piston rod of the hydraulic cylinder 51. A stirring rod 62 is vertically fixed at the drive end of the bottom of the rotating motor 61.

[0025] By starting the rotating motor 61, the stirring blades 63 are driven to fully stir and mix the plastic particles at the bottom of the cylinder 1, and the stirring blades 63 are adapted to the shape of the inner bottom of the cylinder 1, facilitating the full stirring of the plastic particles by the stirring blades 63. After mixing is completed, the hydraulic cylinder 51 can be controlled to contract, thereby pulling up the entire stirring assembly 6, so that the insertion block 64 at the bottom of the stirring rod 62 is disengaged from the first discharge port 12, enabling the mixed plastic particles to be discharged from the first discharge port 12. After discharging is completed, the hydraulic cylinder 51 can be controlled to extend until the insertion block 64 is inserted into the first discharge port 12, facilitating the next mixing operation.
