Packaging bag sealing equipment

The utility model belongs to the technical field of packaging bag sealing equipment, and particularly relates to packaging bag sealing equipment which comprises a main body, a guide plate used for guiding a bag opening is arranged on the outer side of the lower end of a fixing frame, and a clamping plate used for limiting the bag opening is arranged on the other side of the lower end of the fixing frame. After a bag opening is guided through a guide plate to be shrunk towards the inner side, an electric telescopic rod is driven to drive a top plate to clamp and flatten the bag opening, a clamping plate is further used for limiting the bag opening so that the bag opening can enter sealing equipment for sealing treatment, wrinkles generated after the bag opening is sealed can be effectively avoided, and the attractiveness and the working efficiency are improved; a baffle is arranged at the upper end of a main body, the lower end of a limiting frame is placed in a clamping groove after the distance is adjusted t
