Background

Plastic films are films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, and are used for packaging and as a film coating layer. However, since the plastic film is not easily degraded, if the plastic film is directly discarded, the plastic film can damage the environment and even form white pollution, the beauty of the environment is greatly influenced, and the visual stimulation is brought to people. Therefore, after use, the plastic film is usually shredded by a shredding device and recycled. The core component of the equipment for shredding is a rotatable cutter shaft, and the movable cutter on the cutter shaft is matched with the fixed cutter in the cavity of the shredding equipment to shred the plastic film.

However, the cutter shafts with different structures are different in applicable object size, for example, a shredder cutter shaft can only shred a large plastic film into small films with relatively small size, and the size of the obtained small films cannot meet the recycling requirement; the crusher knife shaft can crush small-sized materials into chips, but cannot be applied to large plastic films. Therefore, at present, when plastic films are recycled, a shredder and a crusher are generally integrated into a unit, a shredder cutter shaft firstly shreds large films into small films, and then a crusher cutter shaft shreds the small films into chips meeting the recycling requirement.

However, the use of a shredder in combination with a crusher has a number of drawbacks, firstly, the two machines occupy a large area; secondly, the cost of using two machines simultaneously is high; and finally, the two machines are matched, so that seamless connection cannot be realized, and the working efficiency is lower.
