[0002] Waste plastics is a popular term, which does not refer to waste, old and useless plastic products. For the vast majority of plastic products, especially a large number of disposable ones, the performance of the plastic material itself does not change significantly after use. Therefore, it is entirely possible to recycle and reprocess them into plastic products for reuse by appropriate methods. In all fields of our daily life and agricultural production, plastic products are everywhere. When the lifespan or purpose of these products is reached, they will be discarded and become waste plastics.

[0003] Due to the need for storage and recycling of waste plastics, there are the following treatment methods for waste plastic recycling at present: The first method usually uses a crusher to crush waste plastics, then cleans them through a cleaning device, and then dries them through a drying device, and directly transports them to a hot-melt device for hot-melt granulation; The second method is that some waste plastics are collected, crushed into pieces or fragments by a crusher, then bagged and stacked centrally, and then transported to a plastic processing factory for processing by a transport vehicle, or directly transported to a transport vehicle after the waste plastics are crushed, so that the transport vehicle transports the crushed waste plastics to a plastic processing factory for processing to produce other products.

[0004] Therefore, when some waste plastics are crushed at present, after the crushing device crushes the waste plastics into pieces or fragments and bags them or directly transports them, the garbage stack is relatively loose and not compact.
