Technical Field

[0001] The invention belongs to the technical field of floor manufacturing, and in particular relates to a PE scrap material crushing and recovery device. Background Art

[0002] PE material, also known as polyethylene material, is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, and can withstand corrosion from most acids and alkalis, so it is widely used in various fields.

[0003] In the process of floor manufacturing, a lot of PE scraps will be generated. In order to avoid material waste, they need to be recycled and reused. When recycling waste PE materials, a crusher is needed to crush the waste materials. However, the current crushing device directly introduces the waste into the crusher for crushing and then collects it for secondary utilization. However, a large amount of metal debris, such as steel wire, screws, etc., is easily mixed in the PE waste. The metal debris in the waste will not only damage the production equipment, but also pose a hidden danger to subsequent products, making it inconvenient to carry out the recycling process. In addition, the crusher will also generate a lot of dust and noise pollution during processing, making the production environment too noisy, which is not conducive to the health of workers.

[0004] Therefore, the above problems are issues that should be considered and solved in the process of recycling PE scraps in floor production. Summary of the invention

[0005] In view of the above problems, in order to solve the above technical problems, the present invention discloses a PE scrap crushing and recovery device, and the specific technical solution is as follows: The present invention provides a PE scrap crushing and recovery device, comprising a feeding device, a crusher and a material receiver connected in sequence, the feeding device comprising a first conveyor belt, the outer surface of the first conveyor belt is equidistantly provided with a plurality of baffles, an electromagnet is installed above the first conveyor belt through a bracket, the discharge end of the first conveyor belt is connected to the feed port of the crusher, a primary crushing roller and a secondary crushing roller are arranged inside the crusher, the discharge port of the crusher and the material receiver are connected through a second conveyor belt, a receiving hopper is arranged at the bottom end of the second conveyor belt corresponding to the discharge port of the crusher, a dust suction device is arranged on the top of the crusher, and a shock absorbing device is arranged at the bottom of the crusher.
