Some existing automatic splicing equipment is not accurate in yarn leading, and cannot quickly and accurately guide the two ends of the broken yarn to the appropriate position, resulting in low splicing success rate and affecting the overall production progress. Therefore, we provide a broken yarn automatic splicing equipment to solve the above problems. Utility model content
