The utility model discloses on-line detection equipment for a hook joint of a
metal monofilament, which comprises a rack, and a driven wheel pair, a
visual identification device, a
cutting mechanism, a driving motor and a driving wheel pair which are sequentially arranged along the advancing direction of the
metal monofilament, and the driven wheel pair comprises an upper driven wheel and a lower driven wheel; the upper driven wheel and the lower driven wheel are installed on the
machine frame through an upper driven wheel shaft and a lower driven wheel shaft respectively, a vertical sliding way is arranged on the
machine frame, and the upper driven wheel shaft is installed on the sliding way in a sliding mode. The
visual identification device comprises a camera; the
cutting mechanism is provided with a cutter; the driving wheel pair comprises an upper driving wheel and a lower driving wheel, the upper driving wheel is connected with a driving motor, the lower driving wheel is installed on the
machine frame through a lower driving wheel shaft, and a channel exists between the upper driving wheel and the lower driving wheel. According to the utility model, whether a hook joint exists in the
metal monofilament in the rewinding process can be detected on line, and the hook joint can be quickly
cut off on line when the metal monofilament is detected to meet the hook joint, so that the production safety is improved.
