Automatic bag feeding machine for valve bags

The utility model relates to an automatic bag feeding machine for a valve bag, and aims to solve the technical problems that when the existing equipment is used for automatically feeding the valve bag, the valve bag needs to be lifted by using a moving assembly and then is horizontally moved to be connected with a canning head in an inserting manner, so that the structural complexity of the equipment is increased, and the bag feeding efficiency of the valve bag is influenced. Comprising a mounting plate and further comprises a bag storage box, the bag storage box is fixedly connected with the bottom of the outer side wall of the mounting plate, and a canning head is inserted into the outer side wall of the mounting plate; through combination of the clamping rod, the clamping plate, the third hydraulic cylinder and the adsorption plate, the adsorption plate moves upwards again under the action of the third hydraulic cylinder to open the port of the valve bag, so that the port of the valve bag can be accurately
