Currently, existing waste recycling and reuse equipment has many shortcomings. Most devices can only perform simple collection, lacking effective pretreatment of the waste and failing to accurately separate waste of different particle sizes and properties, resulting in inconsistent raw material quality during subsequent reuse. Furthermore, in terms of waste cleaning, traditional devices struggle to adapt to screens of varying thicknesses and inclination angles, leading to poor cleaning results, screen clogging, and reduced waste recycling efficiency. Simultaneously, existing equipment has a low level of automation, requiring frequent manual operation, increasing labor costs and intensity, and failing to meet the high-efficiency and environmentally friendly production needs of modern feed additive manufacturers. Therefore, improvements to existing technologies are necessary. Utility Model Content

An electric push rod drives the cleaning roller in reciprocating motion, and an electromagnet attracts ferromagnetic impurities and carries them to collection box c. An adaptive mechanism uses spring tension to keep the cleaning roller in constant contact with the screen. When encountering an obstacle, the piston rod and the internal threaded cylinder rotate relative to each other, compressing the spring for adaptive buffering.
