Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling, and in particular to a device for recycling and processing waste materials from laying plastic runways. Background Art

[0002] The plastic track is also called the all-weather track for athletics. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, pigment, additive, filler and other materials. The plastic track has the characteristics of good flatness, not easy to deform, appropriate hardness and elasticity, and stable physical properties. It is conducive to the athletes' speed and technology, effectively improving sports performance, and effectively reducing the risk of athletes falling. The plastic track is composed of polyurethane rubber and other materials. It has certain elasticity and color, certain UV resistance and aging resistance, and is internationally recognized as the best all-weather outdoor sports field floor material. After the plastic track is completed, a large amount of residual material will remain on the construction site. If the residual material is directly discarded, a large amount of raw materials will be wasted, thereby increasing the cost of plastic track construction. Therefore, the residual material needs to be recycled. The existing equipment can collect the residual materials used in the construction of the plastic track to avoid the waste of residual materials. However, most of the plastic tracks in the prior art are difficult to achieve continuous crushing and screening during the decomposition and crushing process, and the existing crushers and cutters are prone to material jamming during continuous cutting. The present invention uses horizontal cutters and linear motion cutters for cutting, which reduces the problem of material jamming and can achieve recycling and classification at the tail end.

Similarly, if the size of the waste can fall into the middle discharge port, the waste will fall into the middle discharge port. If the size of the waste is larger than the width of the middle discharge port, it will be transported to the large discharge port by the conveyor belt. If the size of the waste is still larger than the width of the large discharge port, it will be discharged from the front of the crushing box and put back into the feed hopper for processing.
