[0002] The recycling of waste plastics can not only greatly save resources, but also reduce environmental pollution and improve the quality of the ecological environment. It is an important measure for resource development. When recycling waste plastics, plastic granulators will be used to recycle The plastic raw material is heated and melted into a molten state, and then the molten plastic is extruded into plastic strips and then granulated to obtain plastic granules, so as to facilitate the secondary processing of plastics into industrial products, but the existing recycled plastics Pelletizers often have disadvantages, such as huge size, high power consumption, low energy utilization efficiency, low production efficiency, easy blockage of molten plastic flow, frequent replacement and maintenance of metal filters for filtering impurities, and slow cooling speed of strip plastic Moreover, it is easy to deform, and the plastic particles after cutting are inconsistent in size, low in quality and affect subsequent sales. Therefore, it is necessary for the present invention to provide a plastic granulation equipment, which sequentially heats and melts plastic fragments, filters impurities, and melts them in a molten state. Conveying, water-cooled strip forming, granule cutting and plastic granules, during the impurity filtration process, the impurities can be transported away by the auger after being blocked by the filter screen, so that the filter screen can avoid frequent replacement and maintenance; during the conveying process, the heating element can The plastic is always kept in a molten state and transported to the particle forming device to reduce the probability of clogging; during the water-cooled strip forming process, the cooling water is flowing water and the cooling water is turned over in a vortex manner. The cooling molding effect is better; in the particle cutting process, except for the first test run, the size of the plastic particles obtained in the subsequent normal operation process of the present invention is consistent, without screening, the quality is better, and it is more convenient for subsequent sales. More plastic particles are obtained, and the efficiency is better
