Technical Field

The invention relates to the field of cigarette manufacturing, in particular to a double-length filter defect detection system for a cigarette making machine.

Background

The defect filter detection mode adopted by the current cigarette making machine has large limitation, for example, the ZJ17 type cigarette making machine can only detect whether a 50mm double-length filter passes through a converging drum and then eliminates the filter. However, when defective filters exceeding 50mm ± 0.5mm pass through the converging drum, the rejection cannot be measured and controlled, and thus such defective filters having a fine deviation are very likely to flow into the market, causing a serious product quality risk.
