The invention discloses an empty bag removing device at a conveying section of a wet tissue packaging machine. The empty bag removing device comprises a base, wherein a back plate is arranged on the back side face of the base; a controller is mounted in a cavity in the base; two symmetrical stand columns are mounted on the upper surface of the base; rotary shafts are rotatably connected with top ends of the stand columns and are connected with a power mechanism; rollers are connected with the outer sides of the rotary shafts in a sleeving manner; and a conveyor belt is arranged between the rollers. The empty bag removing device adopts the X-ray detecting manner, can conveniently and efficiently detect whether an empty bag exists in a product, is extremely high in precision rate, unlikely to cause an error, and improves the empty bag detection and removal efficiency; in addition, the controller is adopted to control an electric telescopic rod and then drive a push plate to push an empty bag product out of the conveyor belt and enable the empty bag product to fall down in a collecting box, so that the empty bag is conveniently collected; and moreover, sponge at the bottom end of the push plate can protect the conveyor belt to reduce abrasion.
