Description

Technical Field

[0001] The utility model relates to the technical field of paper medium recycling equipment, in particular to a large-scale paper shredding and baling integrated machine based on PLC control. Background Art

[0002] At present, the recycling of waste paper has become an important issue in social development. However, most of the existing shredder products have the following problems: most of the existing shredders adopt a one-time shredding method. After the paper medium is shredded, the shredded paper becomes strips or granular shreds, and the size is too large. If it is used for the destruction of important documents, there is a risk of restoration. If you want to improve the shredding effect on this basis, you need to optimize the tool processing technology, which is costly and leads to expensive products. There is no sorting device. If there are metal impurities in the paper medium, it will damage the tool, affect the shredding efficiency, and reduce the shredding quality. The shredded waste paper is fluffy and large in size, which is not convenient for storage and recycling. In summary, the existing shredders cannot meet the actual needs well. Utility Model Content

The needle detector, the crushing device and the baler are connected by a conveyor belt. The needle detector detects and sorts materials. The crushing device crushes paper media into shredded paper scraps. The baler collects, compresses and packs the shredded paper scraps. The PLC control cabinet controls the pause and operation of the conveyor belt, thereby realizing the automatic sorting, crushing and packaging of paper media.
