Clamping and conveying mechanism of packaging bag

The utility model aims to provide the clamping and conveying mechanism for the packaging bag, which is consistent in the outlet direction of the packaging bag and simple in structure, two groups of clamping and conveying belts are arranged on a rack at equal height, and a swing arm connected with the clamping and conveying belts is in running fit with the rack through a rotating shaft; power drives the rotating shaft to rotate to drive the two sets of clamping and conveying belts to synchronously swing to the clamping and conveying positions close to each other or the bag feeding positions away from each other, when the clamping and conveying positions are in clamping and conveying positions, the belt faces of the two sets of clamping and conveying belts are parallel to each other and areboth located in the vertical plane, and the adjacent belt faces at the positions form a belt-shaped restraining area. And the length direction of the strip-shaped constraint area is consistent with the bag feeding direction o
