Then, the packaging bag is conveyed forward. During the conveying process, the rotatable pressure roller 4 is attached to the packaging bag, which plays a role in stabilizing and positioning the packaging bag, and ensures that the packaging bag maintains the correct position and posture during the conveying process. When the packaging bag is conveyed to the appropriate position, the driving device is started to drive the wheel shaft 5 to move downward in the frame 1. The punching needle roller 6 on the wheel shaft 5 descends together with the wheel shaft 5, cooperates with the pressure roller 4, and punches the packaging bag. The needles on the punching needle roller 6 penetrate the packaging bag under the action of pressure to form the required holes. After the punching is completed, the driving device drives the wheel shaft 5 to move upward, so that the punching needle roller 6 leaves the packaging bag and returns to the initial position, ready for the next punching operation.
