Then, the swing driving motor 14 drives the swing link frame 12 and the ultrasonic welding base 8 at the front end (the cover of the paper box to be welded has been taken out), and swings downward to the welding cover position (as shown in fig. 17). When the welding pressing guide post 16 swings downwards to a proper position, the pressing cylinder telescopic rod 20 of the pressing driving cylinder 18 pushes the pressing telescopic plate 17, and then the ultrasonic welding base 8 at the front end is driven to move towards the rear side along the welding pressing guide post 16 and in the welding pressing guide sleeve 15 of the swinging connecting frame 12; meanwhile, the welding sliding table cylinder 7 drives the ultrasonic welding head 5 on the welding head sliding seat 6 to move in front of each other, so that the paper box cover 25 to be welded is welded on the packaging paper box 10 by the press welding of the ultrasonic welding head 5 and the ultrasonic welding base 8 (as shown in fig. 17).

In the process of ultrasonic welding the carton cover by the ultrasonic welding joint 5 and the ultrasonic welding base 8, the telescopic end of the cover blocking and cover placing cylinder 49 of the cover blocking and cover placing mechanism 48 is extended, so that the telescopic connecting block 50 drives the cover blocking upper rod 51 and the cover placing lower rod 53 to be linked, and further the carton cover 25 to be welded at the lowest end of the cover conveying guide rail 3 falls onto the cover pushing mechanism 4 below from the cover placing lower rod 53 which is displaced, and the carton cover 25 to be welded falls onto the cover pushing claw 57 at the position of the lower end cover pushing outlet 60 through the cover falling sliding groove 59 of the U-shaped guide groove 54 to prepare for the next cover taking action. At the same time, the upper blocking lever 51 linked with the lower lid-placing lever 53 temporarily blocks the upper lid 25 to be welded to ensure that only one lid passes through each operation (as shown in fig. 13). Subsequently, the telescopic end of the cap-placing cylinder 49 is retracted to the initial cap-placing position. The ultrasonic welding head 5 and the ultrasonic welding base 8 after welding are reversely moved and separated, then the swing driving motor 14 drives the swing connecting frame 12 and the ultrasonic welding base 8 at the front end (the previously taken cover of the paper box to be welded is welded on the packaging paper box), the cover is swung upwards to the cover taking position again, and the paper box conveying mechanism 9 drives the packaging paper box 10 to move forwards by one station so as to carry out the next operation cycle of swinging up to take the cover and swinging down to weld the cover.
