This patented technology involves installing a U-shaped frame at the desired position on the bag-making machine, adjusting the position of the lifting lugs along a threaded rod, thereby changing the position of the hot-cutting blade. This alters the relative position between the hot-cutting blade and the plastic bag. Once the relative position of the hot-cutting blade and the plastic bag meets the requirements, two nuts on the threaded rod restrict the relative position of the lifting lugs and the threaded rod, thus adjusting the position of the hot-cutting blade. This ensures that different parts of the hot-cutting blade contact the plastic bag, which is beneficial for... The hot-cutting blade is worn evenly, improving its utilization rate. The power cord passes through the heat insulation cylinder, and the horizontal part of the L-shaped plate on the heat insulation cylinder is aligned with the convex strip. The connecting screw passes through the small hole and is screwed into the screw hole, completing the connection and fixation between the L-shaped plate and the hot-cutting blade.
