The invention relates to an online detection
system for adhesion of straws to packing boxes, which is disposed on a milk packaging line comprising a transmission chain. The detection
system comprises guide rails arranged on two sides of the chain, an electric eye and a proximity switch are arranged on two opposite sides of the guide rails, the proximity switch is connected with a detection plate, an
electromagnetic valve, an air
pipe and an electric bag blowing
nozzle are arranged on the same side of the proximity switch, the air
pipe and the electric bag blowing
nozzle are connected with the
electromagnetic valve, and the electric eye, the proximity switch and the
electromagnetic valve are controlled by the
control unit. The electric eye is used for detecting milk bags, and when a
straw on the packaging box is abnormal, the lower end of the
straw cannot contact with the detection plate to lead the detection plate to deflect, the proximity switch connected with the detection plate is normally opened, the
control unit controls the electromagnetic valve to get
powder for starting pneumatic equipment, and the electric bag blowing
nozzle blows down the milk bag. By means of the online detection
system, the problem that manual detection and unqualified
product selection are low in efficiency is solved, and production normality is guaranteed.
