This utility model relates to the technical field of packaging machines, specifically a zipper opening mechanism for a
laundry detergent
packaging machine. It includes a zipper guide
assembly, an air-blowing opening
assembly, and a bag-supporting
assembly. The bag-supporting assembly is rotatably connected to the top of the zipper guide assembly. The air-blowing opening assembly is located on one side of the zipper guide assembly and includes an opening column, an opening swing arm, an opening suction tube, and an air blowing
pipe. The opening column is hollow. The opening swing arm and the air blowing
pipe are both fixed to the opening column. One end of the opening suction tube is movably connected to the opening swing arm, and the other end is equipped with a vacuum suction cup. The air blowing
pipe is bent and extends above the vacuum suction cup. This utility model, through the coordinated work of the zipper guide assembly and the air-blowing opening assembly, enables the mechanism to open zipper bags efficiently and accurately. Simultaneously, the bag-supporting assembly keeps the bag opening stable, thus improving the production efficiency of the
packaging machine.
