The second clamping component is connected to the second traction component, and the second traction component is mounted on the rear frame. The cutter component is mounted below the rear frame behind the second clamping component. During operation, the double-layer film roll is first placed on the conveyor rollers. The conveyor mechanism sends the film to the guide mechanism, where it is guided by the guide rollers to pass between the heating element and the pad of the sealing mechanism. The sealing mechanism heat-seals the first section of film. Then, the first section of film passes through the fixed-length guide rollers to the first clamping assembly, which clamps the heat-sealed section. At this point, the sealing mechanism operates again to heat-seal the second section of film. After heat sealing, the first traction assembly pulls the first clamping assembly, moving the first section of film backward a fixed distance along the intermediate frame. Then, the first clamping assembly returns to its initial position and clamps the heat-sealed section of the second section of film. At this point, the sealing mechanism operates once more to heat-seal the third section of film. After heat sealing, the first clamping component pulls the second segment of film backward along the middle frame by a fixed distance. At the same time, the second clamping component of the traction component clamps the heat-sealed part of the first segment of film, and the second traction component pulls the second clamping component to pull the first segment of film backward along the rear frame by a fixed distance. Then, the cutting component cuts the first segment of film. In this way, a film bag with a sealed rear end and an open front end is produced.
