A plastic film recycling apparatus

The application discloses the field of waste plastic recycling, and discloses a plastic film recycling device which is used for cleaning and recycling of the broken plastic film and comprises a cleaning pool, the end of the cleaning pool is provided with a conveying belt arranged obliquely, water filtering holes are formed in the conveying belt, and extrusion components are arranged on the conveying belt; the broken pieces are extruded by the extrusion components, so that the speed of water drainage of the broken pieces is accelerated, and the subsequent recycling process is ensured to be carried out smoothly. The traditional conveying belt only relies on gravity to drain water, and the water in the wet plastic pieces and between the layers of the wet plastic pieces cannot be effectively drained, so that a large amount of water is taken out. In the running cycle of the conveying belt, intermittent extrusion actions are introduced, the squeezing process destroys the "wet cake" structure of the wet material caused by the surface tension of the water film, so that the water is more easily released, the initial moisture content of the material is greatly reduced, the load of the subsequent centrifugal dewatering or hot air drying equipment is effectively reduced, and the energy consumption and operation cost are significantly saved.
