Description

Technical Field

[0002] As a new type of environmentally friendly material, fully degradable starch waste film can be degraded in the natural environment, reducing the burden of plastic waste on the environment. It is widely used in packaging, agriculture and other fields. However, due to some technical difficulties in the production process of fully degradable starch materials, especially in the recycling and reprocessing of waste films, traditional granulation methods, such as thermoplastic plastic granulation, can easily lead to material performance degradation and processing difficulties when processing fully degradable starch materials.

[0003] Prior art CN118664782A discloses a device and method for granulating edge material of a plastic film extrusion production line. The technical proposal discloses, "The present invention discloses a device and method for granulating edge material of a plastic film extrusion production line, belonging to the field of granulation equipment. A device for granulating edge material of a plastic film extrusion production line comprises a frame and a granulation barrel installed inside the frame, wherein the end of the granulation barrel is provided with a discharge port, and the top of the granulation barrel is fixedly connected to a feed hopper. The device also comprises: a screw rod, which rotates inside the granulation barrel through a bearing to extrude and granulate the edge material; a servo motor, which is fixed to the bottom of the frame and is used to drive the end of the screw rod; the present invention can cool the inside of the screw rod, thereby cooling the heated plastic in the granulation barrel, and can distinguish between qualified and unqualified plastic particles, thereby preventing unqualified plastic particles from affecting subsequent processing. At the same time, the plastic particles can be better cooled by air during transportation to prevent the impact of excessive accumulation of plastic particles."

[0004] Although the prior art has disclosed a device and method for granulating edge material of a plastic film extrusion production line, there are still some shortcomings. Specifically, in actual use, the granulation equipment does not perform corresponding crushing and cleaning processes before melting the waste film, resulting in impurities and larger particles that may be contained in the waste film affecting the granulation effect and product quality. In addition, the cooling efficiency of the granulation equipment is low during the cooling process, making it difficult to ensure uniform cooling of the particles. Summary of the Invention
