Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle recycling, in particular to a plastic particle recycling and manufacturing device. Background Technique

[0002] Existing plastic runway particles are suitable for track and field runways, with good flatness, compressive strength, hardness, elasticity and stable physical properties. During installation, it is necessary to keep the same batch of particles in similar sizes, which is beneficial to the performance of athletes' speed and skills. When recycling, plastic particles of different sizes are directly collected, and the recycling device cannot effectively screen them. Therefore, when the plastic particles are reused, due to different sizes, there will be errors in the flatness of the runway surface, which will affect the performance of athletes. There is room for improvement. Among them, a recycling device for plastic runway particles with the application number "CN202320557065.0", this recycling device for plastic runway particles, by setting a screening mechanism, conveys the plastic particles in the recycling box to the screening net through the feeding plate, so that the screening net screens the plastic particles to obtain plastic particles of the same size, thereby effectively improving the quality of runway laying when the plastic particles are reused. However, there is still room for improvement in the use of this recycling device: plastic particles will be worn and aged during long-term use. When they cannot meet the continued use requirements, resource utilization is achieved through recycling and remanufacturing. This recycling device cannot crush plastic particles of different sizes, so separate crushing and processing are required during remanufacturing, which affects the processing efficiency.
