Technical Field

[0001] The invention relates to the technical field of packaging bag clamping, in particular to a packaging bag clamping mechanism of a weighing exchange mechanism of a full-automatic packaging machine. Background Art

[0002] In actual production and preparation, especially the order volume of flexible packaging for pesticides and food packaging has increased dramatically, and the packaging requirements have become more stringent and the packaging varieties have become more complex. In particular, due to the export requirements of the pesticide industry and the domestic restrictions on the production of highly polluting emulsions, powders have become more and more popular. However, due to the factors such as the increasingly fine powders, lighter specific gravity, large changes in density due to environmental influences, and large packaging doses, packaging is difficult. At present, this large-dose powder packaging is mainly done by manual packaging and semi-automatic machine packaging. For manual packaging, the main features are high packaging strength, low output, poor quality, and considerable harm to the human body.

[0003] When automatic packaging is performed, especially when filling is completed, weighing is required, and the packaging bags are fully transferred to the weighing equipment. The existing technical solutions cannot effectively transfer and avoid spilling, so improvements are needed. Summary of the invention
