The pneumatic fingers are driven by the cylinder to move downward, and the two clamping fingers of the pneumatic fingers are in an open state and drive the first clamping plate and the second clamping plate to move downward. The pneumatic fingers are started to clamp the upper end of the packaging bag body, so that the pressure block moves into the movable groove, the spring contracts, and the press switch is not triggered. The sealing mechanism works normally. When there is no packaging bag at the feeding position, the clamping fingers will cause the pressure block to be inserted into the through hole and press the press switch. The press switch is triggered and the sealing mechanism does not work. Through this arrangement, direct contact between the two sealing strips can be avoided, thereby extending the service life of the sealing strips.
