U), this patented technology can adjust the height of the welding head through the use of a lifting mechanism to ensure stability during use, and it has a simple structure, is easy to use, and improves efficiency during use. The buffer head moves in the docking seat, and the buffer mechanism inside the mounting groove cooperates to ensure that the movable plate is buffered when it descends, reducing the impact force when the welding head descends. However, the buffer mechanism of this design includes two damping rods and two buffer springs, one end of each of the damping rods is fixedly connected to the mounting groove, and the other end of each of the damping rods is fixedly connected to each docking seat. Each of the buffer springs is sleeved on each damping rod, one end of each of the buffer springs is fixedly connected to the mounting groove, and the other end of each of the buffer springs is fixedly connected to each docking seat. The structure of this design achieves a buffering effect through the linkage of the buffer spring and the damping rod. The spring has a certain service life cycle. Long-term use of the spring is prone to elastic deformation and loses its original function, resulting in poor buffering effect, thereby causing the welding head to over-weld the packaging bag, resulting in damage.
