[0002] Plastic is a material with plastic behavior. The so-called plasticity means that it deforms when subjected to external force, and can maintain the state when the force is removed. The elastic modulus of plastic is between rubber and fiber, and it can deform to a certain extent when subjected to force. Soft plastic is close to rubber, and hard plastic is close to fiber. In a narrow sense, plastic refers to a material that has resin (or direct polymerization of monomers during processing) as the main component, and additives such as plasticizers, fillers, lubricants, colorants, etc. as auxiliary components, and can flow and form during processing. Plastic is a synthetic polymer compound that can change its shape freely. Plastic is a material made by synthesizing or condensing monomer raw materials.
[0003] In the production and processing of plastic pipe fittings, a large amount of scraps are generated that can be reprocessed and reused, and the recycled plastic pipe fittings such as tees, crosses and connectors have certain economic value. Since plastic pipe fittings are different from traditional plastic parts, and have a hard texture and a certain toughness, they need to be crushed and recycled by a recycling device. The existing recycling device crushes them in a cutting manner, and cannot crush large plastic pipe fittings. The efficiency and quality are inconsistent, which increases the difficulty of subsequent smelting. Therefore, an efficient crushing device for recycling plastic pipe fittings is provided.
