[0033] Working principle or structural principle: The device is installed using a layered platform support. The upper layer is used for feeding, and the lower layer is used for receiving materials. During operation, EPS waste and auxiliary materials are respectively fed into the crushing box 2 and the auxiliary material feeding bin 11. Inside the crushing box 2, the crushing drive motor 3 drives the two sets of crushing rollers 4 to rotate synchronously in opposite directions through the crushing drive belt 8. During the process, the blades on the upper part of the crushing rollers 4 push the EPS waste towards the center. At the center, the blades and the dividing disc 5 form a shearing crushing and dividing structure. The crushing of the EPS waste is completed by the shearing of the blades. The crushed EPS waste enters the inner cavity of the crushing box 2, while a certain amount of auxiliary material is guided into the auxiliary material feeding bin 11. The crushing chamber 2 is driven by the conveying drive belt 9 to make the conveying screw 6 rotate at a constant speed at the lower part of the crushing chamber 2. The rotating conveying screw 6 conveys the material in the crushing chamber 2 in a directional manner. During the process, the EPS residue and auxiliary materials are evenly mixed by the agitation of the spherical protrusion 10 on the upper part of the conveying screw 6. Then, the material enters the rotating drum seat 14 through the material port at the lower part of the crushing chamber 2. The rotating drum seat 14 rotates at a constant speed on the upper part of the granulation drum seat 13 under the drive of the granulation drive motor 12. During the process, the two sets of granulation pressure rollers 15 are rotated and pressed by the rotating drum seat 14 on the upper part of the granulation disc seat 16. The granulation of the material is completed by the roller extrusion. After that, the granulated material is discharged and collected through the discharge trough seat 18 to complete the granulation recycling work.

[0034] In summary, this granulation and recycling device adopts a vertical layout, integrating the crushing and granulation mechanisms into one unit. Through top-feeding, it can automatically complete the crushing, feeding, mixing, and granulation of EPS waste materials, eliminating the need for manual feeding. This reduces labor costs and effectively improves equipment processing efficiency. It employs a counter-rotating guide roller crushing structure, utilizing paired crushing rollers 4 within the crushing chamber 2, along with the central dividing disc 5, to form a shearing crushing structure. This allows for stable crushing of EPS waste materials. Furthermore, a conveying screw 6 with spherical protrusions 10 is installed at the bottom of the crushing chamber 2, ensuring stable mixing and conveying of the crushed EPS waste materials. This guarantees a stable entry of materials into the granulation mechanism, resulting in uniform and stable feeding, significantly improving the device's operational stability and granulation uniformity.
