Description

Technical Field

[0001] The invention relates to the technical field of foam waste recycling, in particular to a foam waste recycling and processing device. Background Art

[0002] Foam is a material made of foamed plastic particles, referred to as foam. Foam is divided into PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, CR, EVA, bridged PE, SBR, EPDM, etc. Foam has a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixation, easy to use, easy to bend, ultra-thin volume, and reliable performance. Foam is a high-quality material with shock absorption and sound absorption effects. Its application range is very wide, including furniture, building materials, shoe materials, sports equipment, automotive supplies and other industries. All of them operate and use foam products. Due to the wide range of foam applications, whether it is the residual materials generated in the manufacturing process of finished products or the waste generated after the use of finished products, the amount is quite large. When processing some special-shaped foams, it is necessary to cut the regular-shaped foam into special shapes. The cut waste is often recycled and broken into granules, and then melted, heated and extruded again to achieve the reuse of foam waste.

[0003] The existing device cannot compress and squeeze the foam waste, and thicker foam waste cannot smoothly enter between the crushing rollers, which easily affects the crushing efficiency. At the same time, it is also unable to extrude foam waste of different thicknesses, and the adaptability of the device is poor. Summary of the invention
