Description

Technical Field

[0001] This invention belongs to the field of slitting technology for slitting equipment, specifically relating to an automatic trimming and dust removal system based on a slitting machine unit. Background Technology

[0002] With the rapid development of industries such as new energy and semiconductors, the demand for slitting and edge-removing equipment is increasing. An automatic edge-removing and dust-removing system is a device that automates the edge-removing process, offering advantages such as high precision, high efficiency, and high automation. In slitting mills, the surface and edge quality of the strip determines its application. Surface quality can be achieved through a cold-rolled, post-bending straightening machine, while edge quality directly affects its use and value. Traditional processes use edge trimming to remove defects such as edge openings and flared edges. However, this method is inefficient and wasteful, with a single mill wasting tens to hundreds of tons of strip annually. Therefore, how to quickly and accurately process edges has become a major challenge in the slitting and cutting field. Existing processing methods involve edge trimming, resulting in low yield, significant waste, and the need for a dedicated edge-trimming mill, leading to high investment costs and a long payback period. Therefore, an automatic edge-removing and dust-removing system is urgently needed to solve these problems. Summary of the Invention
