[0024] Working principle: When in use, the staff places the inner liner to be welded between the two clamping blocks and starts the two electric push rods 16. The electric push rods 16 push the two clamping blocks to clamp and fix the inner liner. At this time, the staff clamps the film to be welded in the mounting slot 7 of the tray 8. The diameter of the film matches the diameter of the mounting slot 7, so that it can fit tightly with the mounting slot 7 to prevent the film from displacement. At this time, the staff starts the hydraulic rod 3, and the hydraulic rod 3 pushes the mounting plate 4 to rise vertically, thereby driving the film and the bottom of the inner liner to dock and fit through the tray 8 to avoid tilting between the weld between the film and the inner liner and the welding gun.
