[0028] A connecting frame 3 is mounted on the upper surface of the mixing cylinder 1. A drive motor 4 is mounted on the inner wall of the connecting frame 3. The output end of the drive motor 4 is connected to a drive shaft 8 via a coupling. A stirring assembly 9 is mounted on the outer surface of the drive shaft 8. A spiral conveying roller 13 is fixedly connected to the bottom end of the drive shaft 8. The stirring assembly 9 includes a transmission plate 901 mounted on the drive shaft 8. Multiple connecting plates 902 are connected to the outer surface of the transmission plate 901. Multiple stirring blades 904 and multiple stirring rods 903 are connected to the outer surface of each connecting plate 902. The drive motor 4 drives the stirring assembly 9. When the drive shaft 8 rotates, the stirring assembly 9 connected to the drive shaft 8 operates accordingly. Multiple connecting plates 902 on the transmission plate 901 connect the stirring blades 904 and the stirring rod 903. The stirring blades 904 can agitate the plastic granules, masterbatches, and additives over a large range, while the stirring rod 903 penetrates deep into the material to further break up material clumps, creating a strong mixing effect within the mixing cylinder 1. Furthermore, driven by the spiral conveyor roller 13, the material at the bottom can be guided to form a spiral upward or downward flow pattern, achieving efficient color mixing.

[0029] Multiple square rods 11 are connected to the outer surface of the transmission plate 901. Each square rod 11 is connected to a scraper 12. The square rods 11 and scraper 12 can move closely against the inner wall of the mixing cylinder 1 as the mixing assembly 9 rotates. The scraper 12 can scrape off the masterbatch and additives attached to the cylinder wall in time, preventing them from accumulating and clumping on the cylinder wall. For the already clumped parts, the scraper 12 can also scrape them off, so that they can re-participate in the mixing, avoiding the impact of material clumping on the color mixing effect. The bottom surface of the mixing cylinder 1 is connected to the discharge cylinder 5. The outer surface of the discharge cylinder 5 is provided with a valve 6. The design of the discharge cylinder 5 and the valve 6 facilitates the rapid discharge of the mixed plastic particles after the mixing is completed.

[0030] A support frame 7 is connected to the outer surface of the mixing cylinder 1. The support frame 7 provides stable support for the entire mixing device, preventing it from shaking or shifting during operation. A guide rail 14 is connected to the inner wall of the mixing cylinder 1. A sliding support rod 10 is slidably connected inside the guide rail 14. The upper surface of the sliding support rod 10 is connected to the bottom end of the spiral conveying roller 13. A secondary mixing component 15 is installed on the bottom surface of the sliding support rod 10. The cooperation between the guide rail 14 and the sliding support rod 10 provides stable support for the spiral conveying roller 13, ensuring that it runs smoothly when conveying materials without shaking or shifting, thus ensuring the stability of material conveying and mixing effect.

[0031] The auxiliary stirring part 15 includes a plurality of bottom rotating rods 151 fixedly connected with the sliding support rod 10, a plurality of main stirring blades 152 fixedly connected with the outer surface of each bottom rotating rod 151, a plurality of connecting rods 153, a plurality of auxiliary stirring blades 155 fixedly connected with the outer surface of each connecting rod 153, and a scraper 154 fixedly connected with the outer surface of each connecting rod 153 and in contact with the inner wall of the feeding cylinder 5. As the plastic particles continuously enter the mixing cylinder 1, the plastic particles at the bottom gradually increase, and the continuous stirring action of the auxiliary stirring part 15 can prevent the material from being excessively accumulated at the bottom. The rotation of the sliding support rod 10 along with the driving shaft 8 and the guide rail 14 can continuously turn the main stirring blades 152 and the auxiliary stirring blades 155 to turn the material at the bottom, so that the plastic particles at the bottom participate in mixing again, avoiding long-term accumulation of the material at the bottom. This not only improves the mixing effect, but also prevents the material from being preferentially discharged near the valve 6 due to accumulation, ensuring that the mixed material can be uniformly discharged and improving the mixing quality. At the same time, preventing material accumulation also helps to reduce the risk of equipment blockage caused by material accumulation, ensuring stable operation of the equipment. The bottom rotating rod 151 drives the main stirring blades 152 to rotate to turn and stir the material in the central area at the bottom, and the connecting rod 153 and the auxiliary stirring blades 155 stir the material near the inner wall of the feeding cylinder 5. After the plastic particles sink to the bottom of the mixing cylinder 1 due to gravity, the auxiliary stirring part 15 can effectively stir these materials, making up for the defect of insufficient stirring when discharging only through the discharge port 206. The sliding support rod 10 is slidably connected with the guide rail 14, and the auxiliary stirring part 15 is installed on the sliding support rod 10. This structure design makes the auxiliary stirring part 15 more stable during operation. When the screw conveying roller 13 rotates to convey the material, the auxiliary stirring part 15 can work stably and synchronously, providing continuous auxiliary power and stirring action for material conveying. Stable operation of the auxiliary stirring part 15 helps to maintain the continuity and stability of the mixed material.

[0032] The working principle of the utility model is:

[0033] In use, the material to be mixed is added into the mixing cylinder 1 from the feeding assembly 2. The driving motor 4 is started to drive the driving shaft 8 and the stirring assembly 9 to rotate, and the screw conveying roller 13 is also rotated. The rotation of the screw conveying roller 13 can convey the material at the bottom upward to guide the material to form a spiral upward or downward flow pattern to avoid material accumulation. At the same time, the transmission plate 901 in the stirring assembly 9 rotates to drive the connecting plate 902 to rotate, and the connecting plate 902 drives the stirring rod 903 and the stirring paddle 904 to rotate. The stirring paddle 904 is used to stir and mix the plastic particles with high density, and the stirring rod 903 is used to disperse the plastic particles with low density. Through the synergistic effect of multi-shaft stirring, the plastic particles are quickly and uniformly mixed.
