The waste polystyrene foam is also called foam plastic, consists of Polystyrene (PS), a flame retardant and a foaming agent, and is widely used as a packaging material, a daily product, an industrial material and the like due to the properties of light weight, moisture resistance, heat insulation and the like. However, the waste plastic products, especially the polystyrene foam, are flooded to cause disasters, and the pollution to our environment is amazing. The polystyrene foam used as a packaging material and for fast food has huge annual output, but is difficult to crack and degrade at normal temperature after being discarded and not used. If the common garbage disposal mode is deep buried, the soil structure can be damaged, and the yield of grain crops is reduced. If the waste is simply incinerated, the waste will pollute air and atmosphere environment seriously. The waste polystyrene foam plastics are recycled, modified and utilized, so that waste materials can be changed into valuable materials, and the waste polystyrene foam plastics are applied to other fields, and can play a greater role while the pollution degree is reduced. In the recycling process flow of the plastic foam, the centralized transportation is an important link, namely, a waste product purchaser packs and transports the recycled plastic foam to a subsequent processing place in a centralized manner, most of transportation tools are trucks, and the plastic foam is of a structure with innumerable microporous gases inside, so that the plastic foam is light in weight, but large in volume, and in the transportation process, the conditions of superwidth and superheight often occur, so that the related legal regulations are violated, and the great potential safety hazard of roads is also caused.

Specifically, when the device works, firstly, plastic foam is placed into the feeding hopper 4, under the action of the electric heating wire in the feeding hopper 4, the plastic foam is firstly cut into thin strips, then the plastic foam enters the shell 3, the plastic foam is cut into fine particles under the action of the crushing roller 6 in the shell 3, then the crushed plastic foam is blown into the containing bag 10 through the air blowing component 2, and finally the bag opening of the containing bag 10 is sealed. In the device, as a further improvement of the scheme, the electric heating wires 5 are arranged in a vertically spaced and staggered manner. Although the mesh structure can also achieve the purpose of cutting the plastic foam into thin strips, the device has the advantages that firstly, the resistance for pushing the plastic foam to move when the plastic foam is cut is reduced, and secondly, compared with the mesh structure, the electric heating wires 5 arranged at intervals up and down are more convenient to clean.

The bag mouth fixing part is used for fixing the bag mouth of the storage bag 10, and prevents the storage bag 10 from falling off from the shell 3, specifically, when the storage bag is used, the position of the elastic sleeve 15 is firstly adjusted, so that the snap plate 14 can be turned outwards, the bag mouth of the storage bag 10 is sleeved outside the side wall of the discharge port of the shell 3, the position of the elastic sleeve 15 is moved to move the elastic sleeve towards the sharp teeth of the snap plate 14, the sharp teeth of the snap plate 14 are clamped into the storage groove 16 through the elastic restoring force of the elastic sleeve 15, meanwhile, part of the surface wall of the storage bag 10 is clamped into the storage groove 16 through the sharp teeth of the snap plate 14, and the purpose of fixing the storage bag 10 is realized.
